Answer:

Step-by-step explanation:

f(x)= -3(x+1)^2 +2

> -3, Has to negative because its facing down

>(x+1) means it goes to the left 1 unit

> +2 at the end means it goes up by 2 units

Answer:

Step-by-step explanation:

Vertex: (-1,2)

a(x - -1)² + 2

a(x + 1)² + 2

Since it's a concave down, a < 0

-3(x + 1)² + 2

Solve for DG. Show all work

Arlecino [84]

32/40 = 24/dg

32dg = 40 x 24

32dg = 960

dg = 960/32

dg = 30

Answer: DG = 30

a ball is dropped from the height of 64 feet. its height can be modeled by the function h(t)=-16t^2+64, where t is the time in s

puteri [66]

Answer:

It takes 1.323 seconds for the ball to fall by 36 feet

Step-by-step explanation:

The height of the ball dropped from a height of 64 ft is modeled by the equation:

h(t) = -16t² + 64 where t is the time in seconds.

To find the time it takes to fall 36 ft, we substitute h(t) too be 36 ft and then solve the resulting quadratic function.

Substituting h(t) to be 36 ft:

36 = -16t² + 64

multiply through by -1

-36 = 16t² - 64

add 36 to both sides

16t² -64 + 36 = -36 + 36

16t² - 28 = 0

add 28 to both sides

16t² - 28 + 28 = 0 +28

16t² = 28

Divide both sides by 28

16t²/16 = 28/16

t² = 1.75

Find squre root of both sides

√t² = √1.75

t = 1.323 seconds

It takes 1.323 seconds for the ball to fall by 36 feet

There are 5280 feet in a mile what factors of a mile is represented by 480 feet

jek_recluse [69]

Remark

I take this to mean "What fraction of a mile." Factors and fractions are two different things. If I have made the wrong assumption, please leave a note.

1 mile = 5280 feet

x mile = 480 feet

Discussion

The easiest way to get the fractional amount is to find the Highest Common Factor and cancel it out. What is left will be your answer.

480:2* 2*2*2 *2 * 3 *5

5280:2*2*2*2*2*3*5*11

The bold primes make up the LCM

Answer

$\frac{1}{11}$ is what is left over.

So 480 is 1/11 of 5280 <<< Answer
