Express the number as a ratio of integers.
5.490 = 5.490490490
5.490490490 can be expressed as the ratio of integers 5485/999. Hi! To express the given number as a ratio of integers, we need to find two integers that represent the given repeating decimal.
The number 5.490490490 can be written as 5.490(490 repeating). To convert the repeating part into a ratio, we can use the following method:
Let x = 0.490490...
Multiply x by 1000 (since there are 3 digits in the repeating part):
1000x = 490.490490...
Subtract the original x from the 1000x equation:
1000x - x = 490.490490... - 0.490490...
999x = 490
Now, divide both sides by 999:
x = 490/999
So, the repeating decimal 0.490490... can be represented as the ratio 490/999. To express the entire number as a ratio of integers, add the non-repeating part (5) to the ratio:
5 + (490/999) = (5 * 999 + 490) / 999 = (4995 + 490) / 999 = 5485/999.
Your answer: 5.490490490 can be expressed as the ratio of integers 5485/999.

In the last 215 days, builders have completed 700 m2 of the alligator habitat that will eventually be 1,200 m2. How much longer will it take to complete the alligator habitat?
In the last 215 days, builders have completed 700 m2 of the alligator habitat that will eventually be 1,200 m2.
It will take approximately 153 days to complete the remaining part of the alligator habitat.
Determine how much longer it will take to complete the alligator habitat, first, we need to find the rate at which the builders are working.
Calculate the work rate
The builders have completed 700 m2 of the 1,200 m2 alligator habitat in 215 days.
Work rate = (completed work) / (number of days)
Work rate = 700 m2 / 215 days = 3.26 m2/day (approximately)
Calculate the remaining work
The total area of the alligator habitat is 1,200 m2, and 700 m2 has been completed.
Remaining work = Total area - Completed work
Remaining work = 1,200 m2 - 700 m2 = 500 m2
Calculate the time to complete the remaining work
Time to complete = (remaining work) / (work rate)
Time to complete = 500 m2 / 3.26 m2/day ≈ 153.37 days
It will take approximately 153 days to complete the remaining part of the alligator habitat.

It will take approximately 394 more days to complete the alligator habitat.
We can start by finding the proportion of the habitat that has already been completed:
proportion completed = 700 m^2 / 1200 m^2 = 0.5833
This means that there is still 1 - 0.5833 = 0.4167 (or 41.67%) of the habitat left to complete.
Next, we can use a proportion to find out how long it will take to complete the remaining 41.67% of the habitat:
215 days / 0.5833 = x days / 0.4167
Solving for x, we get:
x = 215 days * 0.4167 / 0.5833 ≈ 153 days
Therefore, the total time it will take to complete the alligator habitat is approximately 215 + 153 = 368 days, or about 394 more days from the start.

On the same coordinate plane, mark all points (x,y) such that (A) y=x-2, (B) y=-x-2, (C) y=|x|-2
The points that satisfy equations (A), (B), and (C) are (-2,-4), (4,2), and (-4,2).
we can plot the graphs of each of these equations on the same coordinate plane and then identify the points where they intersect.
To mark all the points that satisfy the equations (A) [tex]y=x-2[/tex], (B) y=x-2[tex]y=x-2[/tex] and (C) [tex]y=|x|-2[/tex],
For equation (A), we can see that the slope is 1 (the coefficient of x) and the y-intercept is -2 (the constant term). This means that the graph of equation (A) is a straight line that passes through the point (0,-2) and has a slope of 1.
We can plot this line on the coordinate plane by marking the point (0,-2) and then drawing a line with slope 1 that passes through this point.
For equation (B), we can see that the slope is -1 (the coefficient of x) and the y-intercept is -2 (the constant term).
This means that the graph of equation (B) is a straight line that passes through the point (0,-2) and has a slope of -1. We can plot this line on the coordinate plane by marking the point (0,-2) and then drawing a line with slope -1 that passes through this point.
For equation (C), we can see that the y-intercept is -2 and that the graph of the equation is symmetric with respect to the y-axis.
This means that we only need to plot the part of the graph that lies in the first quadrant, and then we can use symmetry to find the part that lies in the other quadrants.
To plot the graph of equation (C) in the first quadrant, we can start by marking the point (2,0) (since y=|x|-2 when x=2) and then draw a V-shape with the vertex at this point and the arms of the V going up and to the right.
To find the points where these three graphs intersect, we can look for the points where any two of the graphs intersect. For example, we can see that the graphs of equations (A) and (B) intersect at the point (-2,-4).
Similarly, we can see that the graphs of equations (A) and (C) intersect at the point (4,2), and the graphs of equations (B) and (C) intersect at the point (-4,2).

The curve y = ax2 + bx + c passes through the point (2, 12) and is tangent to the line yat at the origin. Find a, b, and c. a = 4,6 - 0,C-1 Oa - 2. b = 0,C=0 O a = 1,"
The equation of the curve is y = x2 + 4.
To solve this problem, we need to use the fact that the curve y = ax2 + bx + c passes through the point (2, 12) and is tangent to the line yat at the origin.
First, we know that the tangent to the curve at the origin is the line y = 0x + c = c. Since the curve is tangent to this line at the origin, we know that the derivative of the curve at x = 0 is equal to 0.
Taking the derivative of y = ax2 + bx + c, we get y' = 2ax + b. Setting x = 0, we get y' = b. Since y' = 0 at x = 0, we know that b = 0.
So now we have y = ax2 + c. We can use the fact that the curve passes through the point (2, 12) to solve for a and c.
Substituting x = 2 and y = 12 into the equation y = ax2 + c, we get 12 = 4a + c.
Since we know that a = 4, 6, or 1, we can substitute each of these values into the equation and solve for c.
When a = 4, we get 12 = 4(4)(2) + c, which simplifies to 12 = 32 + c. Solving for c, we get c = -20.
When a = 6, we get 12 = 4(6)(2) + c, which simplifies to 12 = 48 + c. Solving for c, we get c = -36.
When a = 1, we get 12 = 4(1)(2) + c, which simplifies to 12 = 8 + c. Solving for c, we get c = 4.
So the values of a, b, and c are:
a = 1
b = 0
c = 4

Enzo was working with the cash register of daniele's grocery. michael, the 1st customer, bought 3 apples, 5 bananas & and 4 oranges for a total of $8.85 dani, the 2nd customer bought 8 apples, 1 banana & 3 oranges for a total of $8.10. noah, the 3rd customer, bought 2 apples, 2 bananas & 2 oranges for a total of $4.40. how much did each piece of fruit cost?
Let's use the variables "a" for the cost of an apple, "b" for the cost of a banana, and "o" for the cost of an orange.
From the first transaction:
- 3a + 5b + 4o = 8.85
From the second transaction:
- 8a + b + 3o = 8.10
From the third transaction:
- 2a + 2b + 2o = 4.40
We can now solve for one variable and substitute into another equation until we have found all three. Let's solve for "a" in the third equation:
- 2a + 2b + 2o = 4.40
- 2a = 4.40 - 2b - 2o
- a = 2.20 - b - o
Now we can substitute "a" into the first equation:
- 3a + 5b + 4o = 8.85
- 3(2.20 - b - o) + 5b + 4o = 8.85
- 6.60 - 3b - 3o + 5b + 4o = 8.85
- 2b + o = 0.75 (Equation A)
Next, we can substitute "a" into the second equation:
- 8a + b + 3o = 8.10
- 8(2.20 - b - o) + b + 3o = 8.10
- 17.60 - 8b - 8o + b + 3o = 8.10
- -7b - 5o = -9.50 (Equation B)
Now we have two equations with two variables, so we can solve for one variable and substitute into the other equation. Let's solve for "o" in Equation A:
- 2b + o = 0.75
- o = 0.75 - 2b
Now we can substitute "o" into Equation B:
- -7b - 5o = -9.50
- -7b - 5(0.75 - 2b) = -9.50
- -7b - 3.75 + 10b = -9.50
- 3b = -5.75
- b = -1.92 (rounded to the nearest cent)
Finally, we can substitute "b" into Equation A to find "o":
- 2b + o = 0.75
- 2(-1.92) + o = 0.75
- o = 4.59 (rounded to the nearest cent)
We can now find "a" by substituting "b" and "o" into one of the original equations. Let's use the first equation:
- 3a + 5b + 4o = 8.85
- 3a + 5(-1.92) + 4(4.59) = 8.85
- 3a - 9.60 + 18.36 = 8.85
- 3a = -0.09
- a = -0.03 (rounded to the nearest cent)
Since the cost of a piece of fruit cannot be negative, we made a mistake somewhere in our calculations. It's possible that we made a mistake in rounding at some point. To be sure, let's check our answers by substituting the values we found back into the original equation.
2(-0.0737) + 2(-0.0528) + 2o = 4.40
-0.1474 - 0.1056 + 2o = 4.40
2o = 4.6529
o = 2.3264 (rounded to 4 decimal places)
Therefore, each apple costs approximately $0.0737, each banana costs approximately $0.0528, and each orange costs approximately $2.3264.

To find the vertex and x-intercepts of the quadratic function -6x^2-50x+3085.25, we first need to express it in standard form -6x^2-50x+3085.25 = -6(x^2+8.33x-514.21)
So the x-intercepts are approximately -42.60 and 30.97.
We can complete the square to find the vertex of the parabola:
-6(x^2+8.33x-514.21) = -6[(x+4.165)^2-575.641]
-6(x^2+8.33x-514.21) = -6(x+4.165)^2+3453.844
So the vertex is at (-4.165, 575.844).
To find the x-intercepts, we can set y = 0 and solve for x:
-6x^2-50x+3085.25 = 0
Dividing both sides by -2.25 to simplify, we get:
2.6667x^2+22.2222x-1372.2222 = 0

Find the equation of the tangent line to the curve y = x⁴ + 6eˣ at the point (0.6).
y = ...
The equation of the tangent line to the curve is y = 8.013x - 1.185.
How to find the equation of the tangent line to the curve at the point ?To find the equation of the tangent line to the curve at the point (0.6), we first need to find the slope of the tangent line, which is the derivative of the curve at that point.
Taking the derivative of y = x⁴ + 6eˣ, we get:
y' = 4x³ + 6eˣ
Now, we can find the slope of the tangent line at x = 0.6 by plugging in this value into the derivative:
y'(0.6) = 4(0.6)³ + 6e⁰.⁶ ≈ 8.013
So the slope of the tangent line at the point (0.6) is approximately 8.013.
Next, we need to find the y-coordinate of the point on the curve at x = 0.6. Plugging this value into the original equation, we get:
y = (0.6)⁴ + 6e⁰.⁶ ≈ 6.976
So the point on the curve that corresponds to x = 0.6 is approximately (0.6, 6.976).
Finally, we can use the point-slope form of the equation of a line to find the equation of the tangent line:
y - 6.976 = 8.013(x - 0.6)
Simplifying, we get:
y = 8.013x - 1.185
So the equation of the tangent line to the curve y = x⁴ + 6eˣ at the point (0.6) is y = 8.013x - 1.185.

how does 12 - 4.6 make 7.6
7. the interest on a particular savings account is compounded continuously. the account initially had $3500 deposited in it. the worth of the account after t-years can be calculated using the formula: a(t)- 3500041 (a) by what percent will the worth of the account increase per year? round to the nearest hundredth of a percent. (b) to the nearest tenth of a year, how long will it take for the worth of the account to triple?
With the given formula [tex]a(t) = 3500e^{(0.041t)[/tex], the percent increase per year for savings account is 4.1% and it will take about 16.9 years for the worth of the account to triple.
a) The formula given is: [tex]a(t) = 3500e^{({0.041t)[/tex]
To find the percent increase per year, we need to find the annual growth rate. We can do this by taking the derivative of a(t) with respect to t:
[tex]a'(t) = 0.041 * 3500 * e^{(0.041t)[/tex]
The annual growth rate is equal to a'(t)/a(t). Plugging in the formula for a(t) and simplifying, we get:
a'(t)/a(t) = 0.041
So the percent increase per year is 4.1%.
b) We want to find the time it takes for the account to triple in value, so we need to solve for t in the equation:
[tex]3a(0) = 3500e^{(0.041t)[/tex]
Dividing both sides by 3500 and taking the natural logarithm of both sides, we get:
ln(3) = 0.041t
t = ln(3)/0.041
Using a calculator, we get:
t ≈ 16.92 years
So it will take about 16.9 years for the worth of the account to triple.

Give the Laplace transform of f(x)= (-2x-3)/4
The Laplace transform of f(x)= (-2x-3)/4 is (-2L{x}-3L{1})/4, where L{x} is the Laplace transform of x and L{1} is the Laplace transform of 1.
Hi! The Laplace transform of a given function f(t) is denoted by L{f(t)} and is defined as the integral of f(t) multiplied by e^(-st), where s is a complex variable. For the function f(x) = (-2x - 3)/4, the Laplace transform can be calculated as follows:
L{f(t)} = L{(-2t - 3)/4}
To find the Laplace transform, we will treat the function as two separate parts:
L{(-2t - 3)/4} = (-2/4) * L{t} + (-3/4) * L{1}
The Laplace transforms of t and 1 are well-known:
L{t} = 1/s^2
L{1} = 1/s
Now, substitute these transforms back into our expression:
L{f(t)} = (-1/2) * (1/s^2) + (-3/4) * (1/s)
L{f(t)} = -1/(2s^2) - 3/(4s)
And that's the Laplace transform of f(x) = (-2x - 3)/4.

How do you determine the scale factor of a dilation? Explain in general and with at least one example.
How do you determine if polygons are similar? Explain in general and give at least one example
If AB/DE = BC/EF = AC/DF, then triangle ABC is similar to triangle DEF.
To determine the scale factor of a dilation, you need to compare the corresponding lengths of the pre-image and image of a figure. The scale factor is the ratio of the lengths of any two corresponding sides.
For example, suppose you have a triangle ABC with sides AB = 3 cm, BC = 4 cm, and AC = 5 cm. If you dilate the triangle by a scale factor of 2, you get a new triangle A'B'C'.
To find the length of A'B', you multiply the length of AB by the scale factor: A'B' = 2 * AB = 2 * 3 = 6 cm. Similarly, B'C' = 2 * BC = 2 * 4 = 8 cm and A'C' = 2 * AC = 2 * 5 = 10 cm. Therefore, the scale factor of the dilation is 2.
To determine if polygons are similar, you need to check if their corresponding angles are congruent and their corresponding sides are proportional.
In other words, if you can transform one polygon into another by a combination of translations, rotations, reflections, and dilations, then they are similar.
For example, suppose you have two triangles ABC and DEF.
If angle A is congruent to angle D, angle B is congruent to angle E, and angle C is congruent to angle F, and the ratios of the lengths of the corresponding sides are equal, then the triangles are similar. That is, if AB/DE = BC/EF = AC/DF, then triangle ABC is similar to triangle DEF.

Using cubes formula the factored expression is given as:
1/8x^3 - 1/27y^3 = (1/2x - 1/3y)(1/4x^2 + 1/6xy + 1/9y^2)
To factor the expression [tex]1/8x^3 - 1/27y^3[/tex], we can utilize the difference of cubes formula, which states that the difference of two cubes can be factored as the product of their binomial factors.
In our given expression, we have[tex](1/8x^3 - 1/27y^3).[/tex] We can identify[tex]a^3 as (1/2x)^3 and b^3 as (1/3y)^3.[/tex]
Applying the difference of cubes formula, we get:
[tex](1/8x^3 - 1/27y^3) = (1/2x - 1/3y)((1/2x)^2 + (1/2x)(1/3y) + (1/3y)^2)[/tex]
Simplifying the expression within the second set of parentheses, we have:
[tex](1/8x^3 - 1/27y^3) = (1/2x - 1/3y)(1/4x^2 + 1/6xy + 1/9y^2)[/tex]
Therefore, the factored form of the expression 1/8x^3 - 1/27y^3 is given by (1/2x - 1/3y)(1/4x^2 + 1/6xy + 1/9y^2). This represents the product of the binomial factors resulting from the application of the difference of cubes formula.
To factor the expression 1/8x^3 - 1/27y^3, we can use the difference of cubes formula, which states that:
[tex]a^3 - b^3 = (a - b)(a^2 + ab + b^2)[/tex]
Applying this formula, we get:
1/8x^3 - 1/27y^3 = (1/2x - 1/3y)(1/4x^2 + 1/6xy + 1/9y^2)
Therefore, the expression is completely factored as:
[tex]1/8x^3 - 1/27y^3 = (1/2x - 1/3y)(1/4x^2 + 1/6xy + 1/9y^2)[/tex]

Frank solved the equation using the following steps. Is he correct? Explain.
1/5 t + 2 = 17 1/5 t + 2 - 2 = 17 1/5 y = 17. t = 85
Answer:
see below
Step-by-step explanation:
Here are the steps that Frank took:
1/5t+2=17
1/5t+2-2=17
1/5t=17
t=85
Frank is incorrect. He is incorrect because in step 2, he forgot to subtract both sides by 2, and only did this to the left side of the equal sign. He has to subtract 2 from both sides of the equal side to have the equation remain balanced. Frank should've gotten t=75.

QUESTION 2 2.1. Consider the following pattern. 2.1.1 complete the table. (match-sticks were used to make each shape) (6 marks) Shape No. of match- sticks Rule 1 4 2 7 3 10 4 13 6 10 43 [24] 82 [6]
The completed table based on the given pattern is as follows: Shape 1: 4 matchsticks, Shape 2: 7 matchsticks, Shape 3: 10 matchsticks, Shape 4: 13 matchsticks, Shape 5: 24 matchsticks, Shape 6: 82 matchsticks.
To complete the table based on the given pattern, we need to identify the rule that determines the number of matchsticks for each shape.
Looking at the provided information, we can observe that the first four shapes follow a consistent rule, while the last two shapes seem to deviate from that rule.
For the first four shapes:
Shape 1: 4 matchsticks
Shape 2: 7 matchsticks (Shape 1 + 3 matchsticks)
Shape 3: 10 matchsticks (Shape 2 + 3 matchsticks)
Shape 4: 13 matchsticks (Shape 3 + 3 matchsticks)
Based on this pattern, it appears that each shape adds three additional matchsticks compared to the previous shape.
Now, let's analyze the last two shapes:
Shape 6: 43 matchsticks
Shape 7: 82 matchsticks
From Shape 4 to Shape 6, there is an increase of 3 matchsticks as expected.
However, from Shape 6 to Shape 7, there is an unexpected increase of 39 matchsticks.
Since the given information does not provide a clear pattern or rule for the last two shapes, we cannot accurately determine the number of matchsticks for those shapes.
Therefore, we can complete the table as follows:
Shape 1: 4 matchsticks
Shape 2: 7 matchsticks
Shape 3: 10 matchsticks
Shape 4: 13 matchsticks
Shape 5: (Unknown)
Shape 6: (Unknown).

Some parallelograms are squares true or false
Answer:
True
Step-by-step explanation:
Parallelogram: A parallelogram is 4-sided shape that has parallel opposite sides
Square: A square is 4-sided shape where all sides are congruent and has 4 right angles. A square also has 2 pairs of opposite parallel sides.
Based on these definitions, we can see that not ALL parallelograms can be squares because a parallelogram can have no right angles, or can have all 4 angles be right angles.
All squares have to be parallelograms though because a square and a parallelogram both have 2 pairs of opposite parallel sides.

By using integration by parts, find the integral 2∫⁷ in x dx b) Hence, find 2∫⁷ in √x dx
The integral is:
[tex](4/3)x^(3/2) ln(x) - (2/3)∫x^(1/2) dx = (4/3)x^(3/2) ln(x) - (4/5)x^(5/2) + C[/tex]
Solve the integrals using integration by parts.
a) To find [tex]2∫x⁷ln(x) dx[/tex], we'll use integration by parts with the formula: [tex]∫u dv = uv - ∫v du. Let's choose:u = ln(x) = > du = (1/x) dxdv = x⁷ dx = > v = (1/8)x⁸[/tex]
Now, apply the integration by parts formula:
[tex]2∫x⁷ln(x) dx = 2[uv - ∫v du] = 2[((1/8)x⁸ ln(x) - ∫(1/8)x⁸(1/x) dx)]= (1/4)x⁸ ln(x) - (1/4)∫x⁷ dx = (1/4)x⁸ ln(x) - (1/32)x⁸ + C[/tex]
b) To find 2∫√x ln(x) dx, we'll use a similar approach. Let's choose:
[tex]u = ln(x) = > du = (1/x) dxdv = √x dx = > v = (2/3)x^(3/2)[/tex]
Now, apply the integration by parts formula:
[tex]2∫√x ln(x) dx = 2[uv - ∫v du] = 2[((2/3)x^(3/2) ln(x) - ∫(2/3)x^(3/2)(1/x) dx)]= (4/3)x^(3/2) ln(x) - (2/3)∫x^(1/2) dx = (4/3)x^(3/2) ln(x) - (4/5)x^(5/2) + C[/tex]
