Mathematics
1 answer:
OverLord2011 [107]2 years ago
3 0

Answer:

18

Step-by-step explanation:

1. Create the ratio 12:9

The first number in the ratio is where the length of the shadow will go. The second number is where the length of the building will go.

2. Subtract 21 by 12 to find out how much we have to add to 9. (21-12=9)

3. Add 9 to 9. (18)

We now have 21:18.

Shawna and her best friend Keisha go shopping. The function p(t) = 3x +2x-4x2+ 21 represents how much money each girl spent base
NNADVOKAT [17]

Answer:

\$30

Step-by-step explanation:

we have

p(t)=3x+2x-4x^{2}+21

<em>Find the amount of money that each girl spent</em>

For t= 2 hours

p(2)=3(2)+2(2)-4(2)^{2}+21

p(2)=10-16+21

p(2)=\$15

<em>Find the amount of money that they spend together</em>

Multiply by 2 the amount of money that each girl spent

(2)\$15=\$30

Find the x-intercepts of f(x) = x2 + 7x + 10.
Andrej [43]

Answer:

x = - 5, x = - 2

Step-by-step explanation:

Given

f(x) = x² + 7x + 10

To find the x- intercepts let f(x) = 0, that is

x² + 7x + 10 = 0 ← in standard form

(x + 2)(x + 5) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x + 5 = 0 ⇒ x = - 5

The x- intercepts are (- 5, 0) and (- 2, 0 )
