A swimming pool is a rectangular prism. The pool is 36 feet long and 20 feet wide. What is the total amount of water, in cubic f
Sliva [168]

Answer:

2880\ ft^{3}

Step-by-step explanation:

The computation of the total amount of water needed could be determined by using the volume formula which is shown below:

Volume = L \times W \times D

where

L = length,

W = width,

and D = depth.

Now putting the values to the above formula

Volume = (36\ ft) \times (20\ ft) \times (4\ ft) \\\\= 2880\ ft^{3}                            

Therefore, the  total amount of water needed is 2880\ ft^{3}

We simply applied the above formula

Let f(x) = 5x ^ 2 - x + 1 and g(x) = - 3x . Evaluate the composition (fg)(1)
nlexa [21]
F(x) = 5(-3x) ^2 - (-3x) + 1
f(x) = -8x ^2 + 3x + 1

I have no idea how to do this, so if someone could at least do one of these I’ll be grateful <3
jenyasd209 [6]

Answer:

Answers are below!

Step-by-step explanation:

(2 + g) (8)

= (2 + g) (8)

Add a 8 after the 2, and flip.

= (2)(8) + (g)(8)

= 16 + 8g

= 8g + 16

= (4) (8 + -5g)

Add another 4, then flip.

= (4) (8) + (4) (-5g)

= 32 − 20g

= - 20g + 32

−7 (5-n)

= (−7) (5 + -n)

Add another 7, then flip.

= (−7) (5) + (-7) (-n)

= −35 + 7n

= 7n - 35

Use the distributive property.

a (b + c) = ab + ac

a = 8

b = 2m

c = 1

= 8 × 2m + 8 × 1

Simplify, you get 16m + 8.

Use the distributive property.

a (b + c) = ab + ac

a = 6x

b = y

c = z

= 6xy - 6xz is the answer.

\mathrm{Apply\:the\:distributive\:law}:\quad \\\:a\left(b+c\right)=ab+ac

a=-3,\:b=2b,\:c=2a

=-3\cdot \:2b+\left(-3\right)\cdot \:2a

Apply minus plus rules.

=-3\cdot \:2b+\left(-3\right)\cdot \:2a

Multiply the numbers.

3 x 2 = 6

We know that the form of line passing through point (x₀ , y₀) and having slope m is : y - y₀ = m(x - x₀)

Here the line passes through the point (-2 ,9)

x₀ = -2 and y₀ = 9 and Given : Slope(m) = -14

Equation of the line :

⇒ y - 9 = -14(x + 2)
