Answer:
2a^3 -3a^2 -45a +50
Step-by-step explanation:
The expansion of the product of polynomials is an application of the distributive property. Usually, it needs to be applied several times.
(2a^2+7a-10)(a-5)
= 2a^2(a -5) +7a(a -5) -10(a -5)
= 2a^3 -10a^2 +7a^2 -35a -10a +50
= 2a^3 -3a^2 -45a +50

the ratio of shaded is 8:12 simplified to 3:4
the ration of shaded but with a cross is 7: 12. simplified it least value.
the ration of shaded with a cross and just shaded is 8:12 to 7:12, subtract those and you get 1:12
sooo you're answer is 8:12 - 1:12 to see the shaded with cross

A garden store bought a fountain at a cost of $995.66 and marked it up 100%. Later on, the store marked it down 25%. What was the discount price?
Answer:
248.91500
Step-by-step explanation:
Answer: $1493.49
Step-by-step explanation:
Mark-up formulas:
price=cost+mark-up
mark-up=mark-up percentage×cost
Discount formulas:
discount price=original price–discount
discount=discount percentage×original price
solve
First find the original price. Write 100% as the decimal 1.00 before using it in the equation.
price
= cost+mark-up
= 995.66+1.00×995.66
= 995.66+995.66
= 1,991.32
The original price was $1,991.32.
Now find the discount price. Write 25% as the decimal 0.25 before using it in the equation.
discount price
= original price–discount
= 1,991.32–0.25×1,991.32
= 1,991.32–497.83
= 1,493.49
The discount price was $1,493.49.

Answer:
0 < f(x) ≤ 3/4, or (0, 3/4]
Step-by-step explanation:
x² - x + 1 = x² - x + 1/4 + 3/4 = (x - 1/2)² + 3/4
It is always positive and has a minimum value of 3/4 at x = 1/2
So f(x) is always positive (not equal zero) and has a maximum value of 3/4
Then the range is 0 < f(x) ≤ 3/4, or (0, 3/4]

The volume of the prism that is completely filled with 72 cubes that have edge lengths of 1/2 in. is 9 in³.
What is a prism?A prism is a 3-dimensional shape, with two identical shapes facing each other.
To calculate the volume of the prism, we use the formula below.
Formula:
The volume of the prism (V) = 72×volume of one cubeV = 72L³............. Equation 1Where:
V = Volume of the prismL = Length of the cubeFrom the question,
Given:
L = 1/2 inSubstitute these values into equation 1
V = 72(1/2)³V = 72(1/8)V = 9 in³Hence, the volume of the prism is 9 in³.

You subtract 2x from both sides to get -2x+y=6
:)
Answer:
-2x+y = 6
Step-by-step explanation:
Standard form is ax + by = c.
So we need to move the x term to the left side.
y = 2x + 6
Subtract 2x from each side
-2x + y = 6

The graph shows the vertical displacement y, in centimeters, that a weight bouncing from a spring would achieve if there were no friction, for a given number of seconds, x.
From its resting position, how long does it take the weight to bounce one direction, then the other, and then return to its resting position?
-3s
-6s
-16s or
-32s
It would take 6 seconds for the weight to bounce one direction, then the other, and then return to its resting position
What is a periodic function?
A periodic function is a function that repeats itself at regular intervals. The period of this function is the time taken to complete one oscillation while the amplitude is the distance from the origin to peak.
From the diagram:
Time taken for the weight to bounce one direction, then the other, and then return to its resting position = 7.5s - 1.5 s = 6 s
It would take 6 seconds for the weight to bounce one direction, then the other, and then return to its resting position

There are t boys in class. There are 7 fewer girls in class. How many students are in class in terms of t?
Answer:
[tex]2t-7[/tex]
Step-by-step explanation:
Let "t" represent the boys in the class then the amount of girls will be:
[tex]t-7[/tex]
Total Students = Number of Boys + Number of Girls
Total Students = [tex]t+t-7[/tex]
Total Students = [tex]2t-7[/tex]
Let's use a few example numbers to see if this equation is true...
[tex]t=10[/tex]
[tex]t-7=10-7=3[/tex]
[tex]10+3=13[/tex]
This means that [tex]2t-7[/tex] must also be equivalent to 13...
[tex]2(10)-7=20-7=13\rightarrow $ Correct![/tex]
Another example...
[tex]t=15[/tex]
[tex]t-7=15-7=8[/tex]
[tex]15+8=23[/tex]
This means that [tex]2t-7[/tex] must also be equivalent to 23...
[tex]2(15)-7=30-7=23\rightarrow$ Correct![/tex]
Both examples have been proven to be true therefore there are...

Write an equation that states (x, y) is the same distance from (4, 1) as it is from the x-axis.
The equation that gives all the points (x, y) that are at the same distance from (4, 1) as from the x-axis is:
y = (1/2)*(x - 4)^2 + 1/2.
How we can find the point (x, y)?
First, remember that for a point (x, y), the distance to the x-axis is equal to y.
And we also know that the distance between two points (x₁, y₁) and (x₂, y₂) is:
[tex]d = \sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}[/tex]
The distance between (x, y) and (4, 1) is:
[tex]d = \sqrt{(x - 4)^2 + (y - 1)^2}[/tex]
And this must be equal to y, so we can write:
[tex]y = \sqrt{(x - 4)^2 + (y - 1)^2}[/tex]
This is the equation we need to solve.
We will get:
[tex]y^2 = (x - 4)^2 + (y - 1)^2\\\\y^2 = (x - 4)^2 + y^2 - 2y + 1\\\\0 = (x - 4)^2 - 2y + 1\\\\2y = (x - 4)^2 + 1\\\\y = (1/2)*(x - 4)^2 + 1/2[/tex]
This equation gives all the points (x, y) that are at the same distance of (4, 1) as from the x-axis.
