Mrs. Andretti is having new drapes made for her living
room. The cost of the fabric is $15 per yard. The fee to
make and hang the drapes is $250. She uses the expression
15x + 250 to calculate the total cost of the drapes. Mrs.
Andretti states that x represents the total cost of the fabric.
Is she correct?
• Yes, x represents the total cost of the fabric.
O No, x represents the total cost of the drapes.
• No, x represents the total yards of fabric used.
O No, x represents the total amount of fabric she
already has.
Fabric cost ($15 per yard) and curtain making and hanging ($250). x represents the total cost of the fabric and Mrs. Andretti can use the formula 15x to calculate the fabric cost and add the $250 fixed charge to get the total cost of the curtain.
Why do we determine costs?Cost computation helps in deciding on pricing, manufacturing output, and sales. It also helps in figuring out the costs of the products and services the company sells.
X does not represent the cost of fabric. X represents the number of yards of fabric used.
15x + 250
Could be read as ($15 × # of yards) + $250
She must therefore pay $15 per yard of cloth in addition to the $250 base cost of having them produced and hung.
She may indicate the price of fabric with an additional variable.
Example: Y
Y= 15x
Cost of fabric is equal to $15 per yard × # of yards.

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.
let f(x)=x+2 and g(x)=2x2 + 1
look at picture
The values of x such that f(x) = x + 2 and g(x) = 2^x + 1 if f(x = g(x) are x =0 and x = 1
Calculating the values of xGiven that
f(x) = x + 2
g(x) = 2^x + 1
To find x when f(x) = g(x), we need to set the two expressions equal to each other and solve for x:
f(x) = g(x)
x + 2 = 2^x + 1
Subtracting 1 from both sides:
x + 1 = 2^x
We can solve for x by using trial and error or by using numerical methods.
One solution to this equation is x = 1.
To see why, we can plug x = 1 into both sides of the equation:
x + 1 = 2^x
1 + 1 = 2^1
2 = 2
Another solution is x = 0
0 + 1 = 2^0
0 + 1 = 1
1 = 1
Hence, the solutions are x = 0 and x = 1

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.

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.

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.

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.

In the given questions,
1.Factoring 2x² + 9x + 18:
First, we need to find two numbers that multiply to 2×18=36 and add up to 9.The numbers are 6 and 6, since 6×6=36 and 6+6=12, but we need to adjust them to fit the middle term, which is positive.Therefore, we use 6 and 3: 6×3=18 and 6+3=9.We can write the expression as: 2x²+ 6x + 3x + 18.Now we can factor by grouping: (2x+6)(x+3).The answer is (a) (2x+6)(x+3).2.Factoring x² - 20x + 36:
First, we need to find two numbers that multiply to 36 and add up to -20.The numbers are -2 and -18, since -2×(-18)=36 and -2+(-18)=-20.We can write the expression as: x² - 2x - 18x + 36.Now we can factor by grouping: (x-2)(x-18).The answer is (d) (x-2)(x-18).3.Factoring 2x² - 5x - 3:
We can start by multiplying the first and last coefficients: 2×(-3)=-6.We need to find two numbers that multiply to -6 and add up to -5.The numbers are -6 and 1, since -6×1=-6 and -6+1=-5.We can write the expression as: 2x² - 6x + x - 3.Now we can factor by grouping: (2x-3)(x+1).The answer is (a) (2x-3)(x+1).4.Finding the greatest common factor of 8x² + 18x + 4:
We can start by factoring out any common factors of the coefficients, which is 2.Then we need to find the greatest common factor of the terms with x.The terms are 8x^2 and 18x, and the greatest common factor is 2x.The constant term, 4, is a factor of 2, so we can factor out another 2.The greatest common factor is 2(2x² + 9x + 2).The answer is (d) 4x.5.Factoring 8x² + 18x + 4:

The value of x in the figure such that Ray YU is an angle bisector is 18 degrees
How to determine the value of x in the figureGiven
The figure
Such that Ray YU is an angle bisector
An angle bisector is a line or a ray that divides an angle into two equal parts or halves.
In other words, an angle bisector divides an angle into two smaller angles with equal measures.
The point where the angle bisector intersects the opposite side is the angle bisector point
This means that
2x = 36
So, we have
x = 18
Hence, the value of x in the figure is 18

For problems 6 and 7 set up a proportion and solve.
pleaseeeee helpppp i’ll give brainlist
Using proportions we can find,
6. The weight of the adult bear = 750 pounds.
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°

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 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.
