Answer:

$f(9) =-80$

Step-by-step explanation:

Given

The attached functions

Required

Find f(9)

We have:

$f(x) =-x^2 - 2x + 19$

So:

$f(9) =-9^2 - 2*9 + 19$

$f(9) =-81 - 18 + 19$

$f(9) =-80$

Use the perimeter to find the length of segment AD. This is the distance from A to D. Explain how you found your answer. Please

jekas [21]

Answer:

AD = 5 units

Step-by-step explanation:

Given:

Perimeter = 18 units

BC = 4 units

CD = 3 units

Required:

Length of segment AD

Solution:

Perimeter = AB + BC + CD + AD

We can easily find AB,

AB = 6 units (distance from A to B)

Plug in the values

18 = 6 + 4 + 3 + AD

18 = 13 + AD

Subtract 13 from each side

18 - 13 = 13 + AD - 13

5 = AD

AD = 5 units
