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.

Rina wants to ride the bumper cars 1 time and the Ferris wheel 5 times. It costs 1 ticket to ride the bumper cars and 1 ticket t
Lana71 [14]

Answer:

Rina will need 6 tickets.

Explanation:

Rina needs only 1 ticket to ride the ferris wheel once, and 1 ticket to ride the bumper cars once. If she wants to ride the ferris wheel 5 times, then she'll need 5 tickets since 1 x 5 = 5. If she wants to ride the bumper cars only once, she'll only need 1 ticket since 1 x 1 = 1.

Add the answers together, and you get 6 tickets since 5 + 1 = 6.

Hope this helps! :)

Circle an expression and the variable you would substitute if for in each system y=2x <br>x+3y=14 ​
Len [333]

X=2

Y=4

Multiply top so y values cancel out, so multiple top by -3. Y values cancel out. You combine top and bottom equations, x=2. Plug 2 in first equation for x. Y=4
