Answer:

y = 40 + 30x

Step-by-step explanation:

You dont know how many houses, so you put a variable for it. You have $40 in your wallet. Thats why y = 40 + 30x is your answer.

Can you help stuck on this question for a while ​
stepladder [879]

Answer:

Option B

Step-by-step explanation:

Length of the rectangular sand box is given by the function,

F(x) = 3x³ + 6x - 2

Width of the sand box is represented by the function,

W(x) = 2x² - 4

Area function for the sand box will be,

Area of a rectangle = Length × Width

F(x) × W(x) = (3x³ + 6x - 2)(2x² - 4)

                 = 2x²(3x³ + 6x - 2) - 4(3x³ + 6x - 2)

                 = 6x⁵+ 12x³ - 4x²- 12x³- 24x + 8

                 = 6x⁵- 4x²- 24x + 8

Therefore, Area function will be represented by a polynomial degree of 5.

Option B will be the answer.

What is the height of a triangle when the area is 36 cm and the base is 6 cm
pentagon [3]

Answer:

h = 12 cm

Step-by-step explanation:

Use the formula for area of a triangle A = (1/2)bh,   where b is the base, and h is the height.

Plug in the given information of A = 36, and b = 6, then solve for h

36 = (1/2)(6)h

  36 = 3h        (one half of 6 is 3     (1/2)(6) = 3     )

    12 = h        (divide both sides by 3 to isolate h)

If you run 3 meters per second to the left, where will you be 4 seconds after you pass zero?
LenaWriter [7]

Answer:

12 meters to the left, or -12

Step-by-step explanation:

3 meters per second for 4 seconds

Meaning it's 3 x 4

3 x 4 = 12, so therefore it's -12 meters or just 12 meters to the left.

A 40 of foxes in a wildlife preserve quadruples in size every 13 years. The function y=40•4^4, where x is the number of 13-year
SashulF [63]

Answer:

640 foxes

Step-by-step explanation:

The actual formula is y = 40 * 4^{x}

Now that we have the real formula we would need to find out how many 13 year periods exist in the 26 years that are being used in the question. We calculate this by simply dividing 26 by 13.

26 / 13 = 2 periods

Therefore, now that we know there are 2 periods of 13 years in the 26-year span, we plug this value into the formula and solve for y...

y = 40 * 4^{x}

y = 40 * 4^{2}

y = 40 * 16

y = 640

Finally, we can see that there should be 640 foxes after 26 years.
