Answer:

2 seconds

Step-by-step explanation:

Given

h = - 32t² + 64t

When the frisbee lands the height h = 0, that is

- 32t² + 64t = 0 ( multiply through by - 1 )

32t² - 64t = 0 ← factor out 32t from each term

32t(t - 2) = 0

Equate each factor to zero and solve for t

32t = 0 ⇒ t = 0

t - 2 = 0 ⇒ t = 2

t = 0 represents when the frisbee was thrown

and t = 2 when it lands

Hence it takes 2 seconds for the frisbee to land.

Solve for system of equations<br> −3y−4x=−11<br> 3y−5x=−61<br> ​
Firlakuza [10]
X= 8
Y= -7

If you use elimination:

–3y–4x=–11
3y–5x=–61

Add the two equations and get

–9x=–72

Divide by –9 on both sides

X=8

Substitute 8 in for x

–3y–4(8)=–11

Simplify

–3y–32=–11

Add 32 on both sides

–3y=21

Divide by –3 on both sides

Y=–7
