Answer:
The answer is C.
Step-by-step explanation:
Given formula h(t)=−16t2+v0t+h0 , where v0 is the initial velocity and h0 is the initial height.
In this case, the initial postion is a platform 30ft above ground so h0=+30
The initial velocity is 38 ft/s straight up into the air so v0=+38
h(t)=-16t2+38t+30
When the object hits the ground, h=0.
h=-16t2+38t+30=0
Simplifying 8t2-19t-15=0
(8t+5)(t-3)=0
t=-5/8 or 3
As time cannot be -ve, t=3s. The answer is C.
4 1/7 = (4*100) +(1/7 of 100)= (400+ 14.28)= 414.28
The answer is 414.28
Answer:
400mL/3l
Is the correct answer
Step-by-step explanation:
A) 1.1/1=11/10
B)10.1/1=101/10
C).1/1=1/10
D).01/1=1/100
you put the number you have to multiply the decimal with to get a whole n.o as the decimal
