B. use a formula
C. make a table, chart or list
D. make a model or diagram

Answers

Answer 1

Answer:

The correct option is;

B. Use a formula

Step-by-step explanation:

Given that Jim and Lillian have the dimensions of the wall they want to paint, therefore, in order to know how much paint they need to buy, they should proceed as follows;

1) Determine the quantity of paint required to paint a unit area of the wall, and record the quantity UA

2) Calculate the area, A, of the wall they want to paint, which is 15 ft. × 9 ft. = 135 ft.²

3) The amount of paint needed, AmP is therefore given by the following formula

AmP = A × AU = 135 × AU

Darryl Dixon shoots an arrow at a zombie. The path of the arrow can be modeled with the equation y=-x^2 42x-80, where x is time in seconds and y is the height in feet. How long does it take for the arrow to reach its maximum?

Answers

We need to find time taken to reach arrow to its maximum.

The path of the arrow can be modeled with the equation [tex]y=-x^2+ 42x-80[/tex] .

Differentiating the given equation w.r.t x and equate it to zero.

[tex]\dfrac{dy}{dx}=-2x + 42 \\\\42 - 2x = 0\\\\x = 21\ seconds[/tex]

Putting value of x = 21 sec in given equation, we get :

[tex]y=-x^2+ 42x-80\\\\y = -(21)^2 + (42\times 21) - 80\\\\y = 361 \ feet[/tex]

Therefore, time taken to reach maximum height is 21 seconds.

Factor the following expression: x^2+3x

Answers

Step-by-step explanation:

Hey there!

Given;

[tex] = {x}^{2} + 3x[/tex]

~ Take "X" common.

=[tex]x(x + 3)[/tex]

Therefore, "x" and "x+3" are the factors if the expression.
