Answer:

D. [tex]\frac{12x+20}{5y^3}[/tex]

Step-by-step explanation:

When multiplying 2 fractions, you multiply the numerators and denominators, so we have:

[tex](\frac{3x+5}{y^6})(\frac{4y^3}{5}) = \frac{(3x+5)\cdot 4y^3}{y^6\cdot 5} = \frac{(3x+5)\cdot 4}{y^3 \cdot 5} = \frac{12x + 20}{5y^3}[/tex]

Answer:

4th option

Step-by-step explanation:

[tex]\frac{3x+5}{y^6}[/tex] × [tex]\frac{4y^3}{5}[/tex] ( cancel y³ and [tex]y^{6}[/tex] on numerator/denominator by y³ )

= [tex]\frac{3x+5}{y^3}[/tex] × [tex]\frac{4}{5}[/tex]

= [tex]\frac{4(3x + 5)}{5y^3}[/tex]

= [tex]\frac{12x+20}{5y^3}[/tex]

Answer:

y=-4/3x-4

Step-by-step explanation:

The equation of the line that is perpendicular to the line which has a slope of 3 / 4 and passes through the point ( 0, - 4 ) is equals to [tex]y= \frac{-4}{3} x-4[/tex]

" Equation of line is defined as the equation which represents the set of points using slope."

Formula used

[tex]y=mx+c[/tex]

m = slope of the line

c = y-intercept

Product of the Slopes of perpendicular lines  = -1

According to the question,

Slope of the given line = [tex]\frac{3}{4}[/tex]

Using condition for slope of perpendicular lines we have,

Slope of the line perpendicular to the given line 'm' = [tex]\frac{-4}{3}[/tex]

From given point (0, -4)

Y- intercept 'c' = -4

Substitute the value in the formula to get equation of required line,

Answer:

[tex]\frac{x}{2} *\sqrt{x^{2} +4}[/tex] +[tex]\frac{1}{2}[/tex]*LN(|[tex]\frac{x+\sqrt{x^{2} +4} }{2}[/tex]|) +C

Step-by-step explanation:

we will have to do a trig sub for this

use x=a*tanθ for sqrt(x^2 +a^2) where a=2

x=2tanθ, dx= 2 sec^2 (θ) dθ

this turns [tex]\int\limits {\sqrt{x^{2}+4 } } \, dx[/tex] into integral(sqrt( [2tanθ]^2 +4) * 2sec^2 (θ) )dθ

the sqrt( [2tanθ]^2 +4) will condense into 2sec^2 (θ) after converting tan^2(θ) into sec^2(θ) -1

then it simplifies into integral(4*sec^3 (θ)) dθ

you will need to do integration by parts to work out the integral of sec^3(θ) but it will turn into (1/2)sec(θ)tan(θ) + (1/2) LN(|sec(θ)+tan(θ)|) +C

then you will need to rework your functions of θ back into functions of x

tanθ will resolve back into [tex]\frac{x}{2}[/tex] (see substitutions) while secθ will resolve into [tex]\frac{\sqrt{x^{2} +4} }{2}[/tex]

sec(θ)=[tex]\frac{\sqrt{x^{2} +4} }{2}[/tex]  is from its ratio identity of hyp/adj where the hyp. is [tex]\sqrt{x^{2} +4}[/tex]  and adj is 2 (see tan(θ) ratio)

after resolving back into functions of x, substitute ratios for trig functions:

= [tex]\frac{x}{2} *\sqrt{x^{2} +4}[/tex] + [tex]\frac{1}{2}[/tex]*LN(|[tex]\frac{x+\sqrt{x^{2} +4} }{2}[/tex]|) +C

Deducing from the considered box plot, the number of crates that weigh more than 99.5 pounds is 330 approx.

A box plot has 5 data description.

When we get data which can be compared relatively with each other, for finding quartiles, we arrange them in ascending or descending order.

Quartiles are then selected as 3 points such that they create four groups in the data, each groups approximately possessing 25% of the data.

Left to right is said in assumption that data was arranged increasingly from left to right

We're specified here that:

Total 440 crates is being shipped by company.

The box plot is defined by the points 84, 99.5, 113, 143, 170

The point 99.5 is the first quartile.

There are 75% observations on its right, so 75% of 440 is the number of crates which weigh greater than 99.5 pounds.

We get this value as:

[tex]\dfrac{440}{100} \times 75=330[/tex]

Thus, deducing from the considered box plot, the number of crates that weigh more than 99.5 pounds is 330 approx.

Answer:

$8.95

Step-by-step explanation:

If Ari spent $35.80 for 4 posters and each of the poster price was the same therefore if we want the price for one poster we have to divide $35.80 by four to see the cost for one poster which will be $8.95. If you want to know if the price of each poster was the same you can just multiply $8.95 by 4 and you'll actually see that you got back the same money that Ari used to spend for the four posters .

Answer:

-24/16, -√2, 21/51, 0.42

Step-by-step explanation:

Look at the signs of the numbers. Negative numbers will be on the left, while positive numbers will be on the right. That means -√2 and -24/16 will be on the left, while 0.42 and 21/51 will be on the right.

Part 1:

We can change the negative numbers to decimals to compare them.

-√2 ≈ -1.41

-24/16 = -1.5

-1.5 is smaller, which means the first number in the sequence will be -24/16 and then -√2.

Part 2:

We can also change the positive numbers to decimals to compare them.

0.42 = 0.42

21/51 ≈ 0.41

21/51 is a bit smaller, so the third number in the sequence will be 21/51 and then 0.42.

Answer:

Step-by-step explanation:

Could you show two points need to be calculated? A and D are the same in this case

The probability that at least one of the sides of the triangle is also a side of the octagon is 5/7

A regular octagon has 8 sides, and a triangle has 3 sides

Assume that there is a point on the triangle.

Then we select (3 - 1) points from the (8 - 1) sides.

8 - 1 = 7

3 - 1 = 2

So, the total number of selection is:

Selection = 7C2

Evaluate the combination expression

Selection = 21

Adjacent triangles have 5 lines (one line in common).

So, we have:'

n = 5 - 1

n = 4

The number of ways this points can be selected is:

Selection = 4C2

Evaluate

Selection = 6

The probability that the triangle and the octagon do noth have the same side is:

P= 6/21

The probability that at least one of the sides of the triangle is also a side of the octagon is calculated using the following complement rule

P = 1 - 6/21

Evaluate the difference

P = (21 -6)/21

P = 15/21

Reduce fraction

P = 5/7

Hence, the probability that at least one of the sides of the triangle is also a side of the octagon is 5/7

Answer:

  add the areas of the parts

Step-by-step explanation:

The area of an unusual shape is often easily found by decomposing it into shapes that you have formulas for. Divide the shape into parts, and add the areas of those parts.

__

Alternatively, some shapes are conveniently described by "missing" parts, For example, your "plus shaped" figure may be described as an overall rectangle with rectangles removed from the corners. Then the area of the shape is found by subtracting the missing area from that of the overall rectangle.

__

As a rule, you want the parts to be non-overlapping. That way, you can add the areas of the parts without counting any area twice (or more times). If you have overlapping parts, you need to subtract the area(s) that may be counted multiple times.

__

Sometimes you can take advantage of symmetry, so that you only need to compute part of the total area, then multiply by a factor that takes the symmetry into account.

__

In the attached figure, the dimensions of rectangle A are 6 m wide by 7 m high. The dimensions of rectangle B must be found by adding the width dimensions shown across the top of the figure: 5 m +6 m +6 m = 16 m. It is marked as 4 m high. Then the total area is ...

  area of A + area of B

  = (6 m)(7 m) +(16 m)(4 m)

  = 42 m² +64 m² = 106 m²

This can also be found as the area of the 16 m by 11 m enclosing rectangle, less the two 5 m by 7 m corner cut-outs.

  (16 m)(11 m) -2(5 m)(7 m) = 176 m² -2(35 m²) = 106 m²

Answer:

a. All of the whole - 10/10

b. A tenthof the whole - 1/10

Step-by-step explanation:

Step-by-step explanation:

a. since the entire whole represents a 100% , the number of whole that makes up for 100% is the 10 of the ten parts divided by 10 which is equal to 10.

b. since a whole equals 100% , if divided by 10 the entire 100% becomes 10% each for 10 parts. hence a single part equivalent to 1/10 is 10%
