6a-11=13
add 11 to both sides cross out -11 with +11
13+11 =24
6a=24
divide 6 on both sides
a= 4
it is 20 the answer isnt included.
What is your question ? for help !
Answer:
2.65secs
Step-by-step explanation:
Give:
The function h(t)=−16t(t−7) models
the object will hit the ground at h= 0
h(t)=−16t(t−7)
0= -16t(t−7)
0= -16t^2 + 112
16t^2 = 112
t^2 = 7
t= √7
t=2.65secs
Hence, the object object hit the ground at 2.65secs
