Answer:

4th option

Step-by-step explanation:

L = larger softball and S = smaller softball ,then

L + S = 80 → (1) ← equation based on number of softballs ordered

2.75L + 3.25S = 245 → (2) ← equation based on cost

subtract S from both sides in (1)

L = 80 - S → (3)

substitute L = 80 - S into (2)

2.75(80 - S) + 3.25S = 245 ← distribute parenthesis and simplify left side

220 - 2.75S + 3.25S = 245

220 + 0.5S = 245 ( subtract 220 from both sides )

0.5S = 25 ( divide both sides by 0.5 )

S = 50

substitute S = 50 into (3)

L = 80 - 50 = 30

50 small softballs and 30 large softballs were ordered

A soccer ball is kicked from the top of a 64 ft building into the air at an initial speed of 48 ft/sec. Its flight as a function
FinnZ [79.3K]

Answer:

t = 4 seconds

Step-by-step explanation:

The height of a soccer ball as a function of time is given by :

h(t)=-16t^2+48t+64

We need to find the time when the ball hit the ground i.e. h = 0

Put h = 0 in above equation. So,

-16t^2+48t+64=0\\\\16(-t^2+3t+4)=0\\\\-t^2+3t+4=0

It is a quadratic equation such that,

t = -1 s and t = 4 s

Neglecting -1 s, the ball will hit the ground after 4 seconds.

F(t)=-16t^2+144t. After how many seconds does the toy rocket hit the ground?
Margarita [4]
9 seconds
F(t)=0
0= -16t^2+144t
Than solve for “t”
t=0 or t=9
And 0 seconds doesn’t make sense so it is 9 seconds
