what is expression ?An expression in mathematics is a collection of numbers, variables, and mathematical (such as addition, reduction, multiplication, division, exponentiation, etc.) that express a quantity or value. Expressions might be as basic as "3 + 4" or as complicated as "(3x2 - 2) / (x + 1)". They may also contain functions like "sin(x)" or "log(y)". Expressions can also be evaluated by substituting values for the variables and performing the mathematical operations in the order specified. If x = 2, for example, the formula "3x + 5" equals 3(2) + 5 = 11. Expressions are commonly used in mathematics to describe real-world situations, construct equations, and simplify complicated mathematical topics.
Let B represent the birth weight of a male black bear and A represent the mature weight. The ratio of B to A is supplied to us as 3:1000. As a result, we may write:
B/A = 3/1000
The average birth weight (B) is also reported as 12 ounces. We may use these data to get the average adult weight (A):
[tex]B/A = 3/1000\\12/A = 3/1000\\A = 12/(3/1000)\\A = 4000[/tex]
A male black bear's typical mature weight is 4000 ounces.
To convert ounces to pounds, divide by 16 (since one pound contains 16 ounces):
[tex]4000/16 = 250[/tex]
As a result, an adult black bear weighs 250 pounds.

Thus, the area of the pentagon formed by the given coordinates is:
A = 28.5 sq. units.
Explain about the pentagon?A pentagon is just a five-sided polygon in geometry having five straight sides and five inner angles totaling 540 degrees. A pentagon is a five-sided, flat (two-dimensional), plane geometric form.
The coordinates of polygon are:
A(1,3), B(2,8), C(8, 8), D(10,3), and E(5,-2).
Plot the points on the graph as shown.
The area of a pentagon calculation is used to determine the area of a pentagon with apothem, a, but one side length, s:
A = 1/2 * a * (5s)
a = apothem, of perpendicular distance from the centre.
s = length of side.
From graph:
s = 6 units.
a is calculated using the tan function.
each interior angle of pentagon = 54 degrees.
So,
tan (54/2) = a/ (s/2)
tan (36) = a/3
a = 3*tan (36)
a = 1.90 units
A = 1/2 * 1.90 * (5*6)
A = 28.5 sq. units.
Thus, the area of the pentagon formed by the given coordinates is:
A = 28.5 sq. units.

A sphere has a surface area of 60 square feet. Which choice is the best approximation of its radius? Use 3.14 to approximate pi.\
Answer:
Step-by-step explanation:
The surface area of a sphere is given by the formula:
S = 4πr^2
where S is the surface area and r is the radius of the sphere.
We are given that the surface area of the sphere is 60 square feet. Using the formula above, we can solve for the radius:
60 = 4πr^2
Dividing both sides by 4π, we get:
15/π = r^2
Taking the square root of both sides, we get:
r = sqrt(15/π)
Using 3.14 as an approximation for π, we can evaluate this expression:
r ≈ sqrt(15/3.14)
r ≈ 2.20
Therefore, the best approximation for the radius of the sphere is 2.20 feet.
Answer:
Radius is 2.18

The following ordered pairs are found on the graph of the same line.
(-3,9), (-1,4), (1, -1)
Which one of the following points would NOT be found on the line?
A.(-7,19)
B.(7,-16)
C.(-8,20.5)
D.(8,-18.5)
the point that would not be found on the line is option A, (-7,19).
How to calculate the line?
We can use the equation of the line that passes through these three points to determine which of the given points would not be on the line.
First, we can find the slope of the line using the first two points:
slope = (y₂ - y₁)/(x₂- x₁) = (4 - 9)/(-1 - (-3)) = 5/2
Now, we can use the point-slope form of the equation of a line with the slope we just found and the first point (-3,9):
y - y₁= m(x - x₁)
y - 9 = (5/2)(x + 3)
Simplifying this equation gives us:
y = (5/2)x + (27/2)
We can check that the third point (1,-1) also lies on this line by plugging in the values of x and y into the equation above.
Now, we can check which of the given points would not be on this line by plugging in the values of x and y into the equation above.
A. (-7,19): y = (5/2)(-7) + (27/2) = 5.5, which does not equal 19, so this point is not on the line.
B. (7,-16): y = (5/2)(7) + (27/2) = 22.5, which does not equal -16, so this point is not on the line.
C. (-8,20.5): y = (5/2)(-8) + (27/2) = 4.5, which does not equal 20.5, so this point is not on the line.
D. (8,-18.5): y = (5/2)(8) + (27/2) = 25.5, which does not equal -18.5, so this point is not on the line.
Therefore, the point that would not be found on the line is option A, (-7,19).

a package contains 6 blue, 4 red, and 5 yellow gumballs. You randomly choose a gumball from the bag, and you do not replace it. Then you randomly choose another gumball. What is the propobility of both gumballs not being red?
The probability of both gumballs not being red is 11/21.
What is the probability?
The probability of the first gumball not being red is:
P(first gumball not red) = P(blue) + P(yellow)
= (6/15) + (5/15)
= 11/15
After removing the first gumball, there are 14 gumballs left in the bag. The probability of the second gumball not being red depends on what color the first gumball was.
Case 1: The first gumball was blue
If the first gumball was blue, there are 5 blue, 4 red, and 5 yellow gumballs left in the bag. The probability of the second gumball not being red is:
P(second gumball not red | first gumball was blue) = P(blue or yellow)
= P(blue) + P(yellow)
= (5/14) + (5/14)
= 5/7
Case 2: The first gumball was yellow
If the first gumball was yellow, there are 6 blue, 4 red, and 4 yellow gumballs left in the bag. The probability of the second gumball not being red is:
P(second gumball not red | first gumball was yellow) = P(blue or yellow)
= P(blue) + P(yellow)
= (6/14) + (4/14)
= 5/7
The probability of both gumballs not being red is the product of the probabilities of each event:
P(both gumballs not red) = P(first gumball not red) * P(second gumball not red | first gumball not red)
P(both gumballs not red) = (11/15) * (5/7)
P(both gumballs not red) = 55/105
P(both gumballs not red) = 11/21
Therefore, the probability of both gumballs not being red is 11/21.

Statement B is true: The population will increase by 9%.
What are function's different types?Various Functions:
A single function (Injective function) Many – one function. From onto function (Surjective Function) Function is into. polynomial operation.
P(t)=18,751(1.09)t is the population function, where t is the time in years.
The function's growth factor or multiplier, which is bigger than 1, is represented by the expression (1.09t). In other words, the population is growing over time.
Finding the difference between the final and starting values, dividing by the initial value, and then multiplying by 100% will give us the percentage growth in the population.
Let's contrast the population at t=0 and t=1 to see how they differ:
P(0) = 18,751(1.09)^0 = 18,751
P(1) = 18,751(1.09)^1 = 20,436.59
In the last year, the population has grown from 18,751 to 20,436.59.
The population has grown by the following amount:
[(20,436.59 - 18,751)/18,751] × 100% ≈ 9.0%

Multiply, Final answer needs to be in Standard Form.
−5m (−2m + m^2 − 4m^3 + 9)
Answer:
Using the distributive property, we can multiply -5m by each term inside the parentheses:
-5m(-2m + m^2 - 4m^3 + 9) = (-5m)(-2m) + (-5m)(m^2) + (-5m)(-4m^3) + (-5m)(9)
Simplifying each term:
= 10m^2 - 5m^3 + 20m^4 - 45m
The terms are arranged in descending powers of m, so this is already in standard form. Therefore, the final answer is:
20m^4 - 5m^3 + 10m^2 - 45m.
Find the area of a square that has a side length of 2x + 4. Write your answer in standard
form without any spaces and use ^ to indicate an exponent, if necessary.
As given:
The side of the Square= (2x+
As we know:
The area of a square = Side × side
Putting the values of side in above formula we get:
Area = (2x+4) ×(2x+4)
on solving we get:
Area= 2x×2x + 2x×4 +4×2x + 4×4
Area= 4x^2 + 8x + 8x + 16
Area= 4x^2 + 16x + 16
Hence,The Area of the Square is (4x^2+ 16x +16)
The perimeter of the base of a square pyramid is 48 inches. The height of the pyramid is 8 inches. What is the surface area of the pyramid? Responses
Answer:
To find the surface area of a square pyramid, you need to find the area of the base and the area of the four triangular faces, and then add them together.
First, let's find the length of one side of the base of the pyramid:
Perimeter of the square base = 4 x side length
48 inches = 4 x side length
Side length = 12 inches
Now we can find the area of the base:
Area of the base = side length squared
Area of the base = 12 inches x 12 inches
Area of the base = 144 square inches
Next, we need to find the area of each triangular face. To do this, we need to find the length of the slant height of the pyramid. We can use the Pythagorean theorem to do this:
Slant height squared = height squared + (1/2 base length) squared
Slant height squared = 8 inches squared + (6 inches) squared
Slant height squared = 64 inches squared + 36 inches squared
Slant height = square root of (64 + 36) inches
Slant height = 10 inches
Now we can find the area of each triangular face:
Area of a triangular face = (1/2 base length) x slant height
Area of a triangular face = (1/2 x 12 inches) x 10 inches
Area of a triangular face = 60 square inches
Finally, we can add the area of the base and the area of the four triangular faces together to find the total surface area of the pyramid:
Total surface area = Area of the base + (4 x Area of a triangular face)
Total surface area = 144 square inches + (4 x 60 square inches)
Total surface area = 384 square inches
Therefore, the surface area of the pyramid is 384 square inches.
Factor by substitution: (3y−2)2−(3y−2)−2.

b) after 6 months, balance, = $520.40
c) After 9 months , balance = $531.07
d) After 1 year, balance = $542.50
3)
the interest earned in year 1 is $80,

the interest earned in year 2 is $86.40,
the total balance at the end of year 2 is $1166.40, and t
he interest earned in year 3 is $93.31, and
the total balance at the end of year 3 is $1259.71.
4)

A check register balance is the amount of money in a bank account, as recorded by the account holder in their check register, after accounting for deposits, withdrawals, and fees.
1)
The check register balance is not correct. To find the correct balance, we need to adjust the statement ending balance for the outstanding deposits, subtract the outstanding check and service charge, and add any other transactions that may have been missed.
Adjusted balance for outstanding deposits: $41.27 + $27.70 + $12.30 + $102.43 = $183.70
Adjusted balance for outstanding deposits minus the outstanding check: $183.70 - $10.98 = $172.72
Adjusted balance for outstanding deposits minus the outstanding check minus the service charge: $172.72 - $5.82 = $166.90
Therefore, the correct check register balance is $166.90.
2)
To find the balance of the savings account after various time periods, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A = the balance after time t
P = the principal (initial deposit)
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the time period (in years)
For this problem, we have:
P = $500
r = 0.04
n = 4 (compounded quarterly)
t = 0.25 (3 months), 0.5 (6 months), 0.75 (9 months), 1 (1 year)
After 3 months:
A = $500(1 + 0.04/4)^(4*0.25) = $510.08
After 6 months:
A = $500(1 + 0.04/4)^(4*0.5) = $520.40
After 9 months:
A = $500(1 + 0.04/4)^(4*0.75) = $531.07
After 1 year:
A = $500(1 + 0.04/4)^(4*1) = $542.50
Therefore, the balance of the savings account after 3 months is $510.08, after 6 months is $520.40, after 9 months is $531.07, and after 1 year is $542.50.
3)
To find the interest earned and total balance at the end of each year, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A = the balance after time t
P = the principal (initial deposit)
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the time period (in years)
For this problem, we have:
P = $1000
r = 0.08
n = 1 (compounded annually)
t = 1 (year)
After year 1:
Interest earned = $1000 x 0.08 = $80
Total balance = $1000 + $80 = $1080
After year 2:
Interest earned = $1080 x 0.08 = $86.40
Total balance = $1080 + $86.40 = $1166.40
After year 3:
Interest earned = $1166.40 x 0.08 = $93.31
Total balance = $1166.40 + $93.31 = $1259.71
Therefore, the interest earned in year 1 is $80, the total balance at the end of year 1 is $1080, the interest earned in year 2 is $86.40, the total balance at the end of year 2 is $1166.40, and the interest earned in year 3 is $93.31, and the total balance at the end of year 3 is $1259.71.
4)
We can use the formula for compound interest to calculate the interest earned and total balance at the end of each year for each savings account:
$100 at 7% for 4 years:
P = $100, r = 0.07, n = 1 (compounded annually), t = 4
Interest earned = $100 x 0.07 x 4 = $28
Total balance = $100 + $28 = $128 after 4 years
$500 at 8% for 3 years:
P = $500, r = 0.08, n = 1 (compounded annually), t = 3
Interest earned = $500 x 0.08 x 3 = $120
Total balance = $500 + $120 = $620 after 3 years
$300 at 6% for 5 years:
P = $300, r = 0.06, n = 1 (compounded annually), t = 5
Interest earned = $300 x 0.06 x 5 = $90
Total balance = $300 + $90 = $390 after 5 years
Therefore, the interest earned by the $100 savings account is $28, and the total balance at the end of 4 years is $128.
The interest earned by the $500 savings account is $120, and the total balance at the end of 3 years is $620.
The interest earned by the $300 savings account is $90, and the total balance at the end of 5 years is $390.

7. The measure of each angles are: 10°, 75° and 95°
Define proportions?In general, the term "proportion" refers to a part, share, or amount that is compared to a whole.
According to the definition of proportion, two ratios are in proportion when they are equal. Two ratios or fractions are equal when an equation or a declaration to that effect is utilized.
Here in the question,
The weight is in the ratio = 3:1000
The average birth weight = 12 ounces = 3/4 pounds.
Now the weigh of adult bear = 1000 × 3/4 = 750 pounds.
In the second part the angles are in the ratio, 2:15:19.
So, 2x+ 15x + 19x = 180
x = 180/36
x = 5
Hence, the measure of each angles are: 10°, 75° and 95°

The solutions to the quadratic equations are as follows
4a. The rocket was launched from an initial height of 10 meters.
b. The maximum height of the rocket was 55 meters.
c. The rocket reaches its maximum height at 3 seconds
d. the rocket is in the air for t = 6.316 seconds
5. when the horizontal distance is 1 foot, the height of the balloon is 8.875 feet
b. when the horizontal distance is 33 feet, the height of the balloon is 0.875 feet.
How do we solve the quadratic equation?The function is a quadratic equation, and here is how we solve each problem;
a. The initial height of the rocket is the value of h when t=0. So we substitute t=0 into the equation to find:
h = -5(0)² + 30(0) + 10 = 10 meters
b. & c. The maximum height of a projectile launched upward occurs at the vertex of the parabola represented by the quadratic function. For a quadratic function in the form y = ax² + bx + c, the time at which the maximum (or minimum) occurs is -b/2a. In this case, a = -5 and b = 30. So:
t = -b/2a = -30 / (2×-5) = 3 seconds
So, the rocket reaches its maximum height at t=3 seconds. We can find this maximum height by substituting t=3 into the equation:
h = -5(3)² + 30(3) + 10 = -5×9 + 90 + 10 = 45 meters
The rocket is in the air from the time it was launched until it hits the ground. The time when it hits the ground is when h = 0. So we can set the equation to 0 and solve for t:
0 = -5t² + 30t + 10
This is a quadratic equation and can be solved using the quadratic formula: t = [-b ± √(b² - 4ac)] / (2a)
Let's calculate the roots:
t = [-30 ± √((30)² - 4×-5×10)] / (2×-5)
= [-30 ± √(900 + 200)] / -10
= [-30 ± √(1100)] / -10
= 6.316 or -0.32
5. a. To find the height of the balloon when d=1, we substitute d=1 into the equation:
h = -1/8(1)²+ 4(1) + 5 = -1/8 + 4 + 5 = 8.875 feet
b. To determine whether the balloon hits your enemy, we need to see if the balloon's height (h) is above ground level (h > 0) when d=33. So, we substitute d=33 into the equation:
h = -1/8(33)² + 4(33) + 5
h = -1/8×1089 + 132 + 5
h = -136.125 + 132 + 5
h = 0.875 feet
when the horizontal distance is 33 feet, the height of the balloon is 0.875 feet. This means the balloon is above ground level and therefore would indeed hit your nemesis standing 33 feet away.

Complete the square to write an equation in general form of 4x2 – 9y2 + 24x + 18y – 9 = 0 in the standard form shown below, and then identify the key features of the graph.
h = center: (, )
k =
a = slope of asymptote:
b =
The equation is now in the standard shape of a hyperbola, as per the provided assertion. [(x - h)² / a²] - [(y - k)² / b²] = 1
What, in plain words, is a hyperbola?A curve formed by the junction of a double right-angled cone and a plane that slices one half of the cone. a plane curve produced by a point so mobile that the difference between its distance from two fixed locations is a constant.
To complete the square for the given equation, we will group the x and y terms and complete the square separately for each.
4x² + 24x - 9y² + 18y - 9 = 0
4(x² + 6x) - 9(y² - 2y) = 9
4(x² + 6x + 9 - 9) - 9(y² - 2y + 1 - 1) = 9
4(x + 3)² - 9(y - 1)² = 36
Dividing by 36, we get:
(x + 3)² / 9 - (y - 1)² / 4 = 1
So, the equation is now in the standard form of a hyperbola:
[(x - h)² / a²] - [(y - k)² / b²] = 1
where h and k are the coordinates of the center, a is the distance from the center to the vertices along the x-axis, b is the distance from the center to the vertices along the y-axis, and the slope of the asymptotes is b/a.
Comparing with the standard form, we can see that:
h = -3, k = 1, a = 3, b = 2, and the slope of the asymptotes is b/a = 2/3.
The center is (-3, 1). The hyperbola opens horizontally, and its vertices are located at (-3 + a, 1) and (-3 - a, 1). So, the vertices are (-6, 1) and (0, 1).
The asymptotes are two straight lines passing through the center with a slope of ±(b/a) = ±2/3. So, the equations of the asymptotes are y - 1 = (2/3)(x + 3) and y - 1 = -(2/3)(x + 3), which simplify to y = (2/3)x + 5/3 and y = -(2/3)x + 1/3.
The distance between the center and the foci is c = sqrt(a² + b²) = √(13). The foci are located at (-3 + c, 1) and (-3 - c, 1). So, the foci are approximately (-0.16, 1) and (-5.84, 1).
The graph of the hyperbola looks like two mirrored U-shaped curves, with the vertices being the endpoints of the transverse axis.
The asymptotes intersect at the center and divide the hyperbola into four parts, called branches. The foci are located on the transverse axis, inside the branches.
