Answer:
y=4x-9
Step-by-step explanation:
-9=y intercept
up 4 over 1
4/1=4
slope =4
Answer:
r=-2, y=-3
Step-by-step explanation:
<span>What is the surface area of the figure?
0.5x0.5=0.25
0.4x0.5=0.2 that for two so do that again 0.2+0.2=0.4
0.25+0.4= 0.65
A
I hope this helps</span>
For question number 1:The plot H = H(t) is the parabola and it reaches its maximum in the moment when exactly at midpoint between the roots t = 0 and t = 23. At that moment t = 23/2 or 11.5 seconds.
For question number 2:To find the maximal height, just simply substitute t = 11.5 into the quadratic equation. The answer would be 22.9.
For question number 3:H(t) = 0, or, which is the same as -16t^2 + 368t = 0.Factor the left side to get -16*t*(t - 23) = 0.t = 0, relates to the very start of the process, when the ash started its way up.The other root is t = 23 seconds, and it is precisely the time moment when the bit of ash will go back to the ground.
