Answer:
12 years
Step-by-step explanation:
Given that Mr. Hon purchases a new car every 4 years. Ms. Jasper purchases a new car every 6 years.
Assuming that they purchase new cars together after n years.
So, n must a multiple of 4 as well as multiple 6, i.e the number n is the lowest multiple (LCM) of 4 and 6.
As LCM od 4 and 6 is 12, so n=12.
Hence, after 12 years they will purchase news cars together.
Answer:
<h2>84feet</h2>
Step-by-step explanation:
Given the height of the ball modelled by the equation h(t)=16t²+84 after t secs. At the maximum height, the velocity of the ball is zero.
Velocity V is the change of rate of displacement.
V = dh/dt = 32t
0 = 32t
t = 0secs
at t = 0;
h(0) = 16(0)²+84
h(0) = 84feet
This shows that the maximum height of the ball is 84feet
so to find the slope we do y2- y1/ x2-x1
plug in the coordinates: (-6,4) (0,3)
3-4/ 0--6
3-4/0+6
= -1/6
Then using the formula of slop intercept form: y=mx+b........ use one of the coordinates to plug in
4= -1/6x+b...... multiply -6/1 on both sides of equation ( you do this so -1/6 and -6/1 can cancel out)
-24=b........ Use b to plug in y=mx+b---------> y= -1/6x-24
