I dont know if the "2" at the beginning is involved and is getting multiplied (ex. 2x3/7)
but if it is,i would sat 27/28 is the answer
Answer:
$7
Step-by-step explanation:
just did 21 divided by three since it says she has saved one third of the $21.
If the 2 lines are parallel, their slopes are the same.
The slope of both is
3+3
m = ---------- = 3
2 - 0
If the new line <span>passes through the point (−1, −1), then the equation in point slope form is:
y+1 = 3(x+1).</span>
720 divided by 8 and then look up the answer to that as a fraction on Google
Given that height, h(t) of a tennis ball is modeled by the equation h(t)=<span>-16t^2 + 45t + 7, the time taken for the ball to reach maximum height will found as follows:
at maximum height:
h'(t)=0
but from the equation:
h'(t)=-32t+45=0
solving for t we get
t=45/32
t=1.40625~1.4 seconds
Thus the time taken to reach maximum height is 1.4 seconds
