Answer:
Therefore it will take s for the object to reach the ground.
Step-by-step explanation:
Given function is
H(t) = -64 t²+169.
where H is height in feet, and t is time in second.
When the object touches the ground, the height of the object will be zero.
i.e H(t) = 0.
Therefore
H(t) = 0
⇒ -64 t²+169=0
⇒ -64 t²= -169
[ square root both sides]
Time can not be negative.
Therefore
Therefore it will take s for the object to reach the ground.
Answer:
2055.15
Step-by-step explanation:
A(1+r)^n=4000
A is the money that she need to invest
r is rate
n is the time( depend on monthly or yearly rate)
A(1+4.25%)^16=4000
A=2055.15
10-4=6 im not s. sure rhia ia correct. What grade are you in?
-16 ( -2 +y) - 3y= -25
32 -16y -3y = -25
32 - 19y = -25
-32. -32
-19y =-57
y=3
