Answer:
t = 2secs
Step-by-step explanation:
Given the height above the surface expressed as h = -16t^2 + 64 t + 80.
The velocity of the rocket at its maximum height is zero. Hence;
v(t) = dy/dt = 0
dy/dt = -32t + 64
0 = -32t + 64
32t = 64
t = 64/32
t = 2secs
Hence the rocket will hit the lake after 2 secs
Answer:
for the first 2 neither one is a polygon because a polygon has straight sides and is closed connections were the first shape has an open connection and the second shape has a curved line. for question i believe is 48 and question 4 is 145.
explanation.
for the last 2 problems their total equal 360 so you just add up all the side then subtract the number you got by 360 and that's your answer. ex.) 120 +130+ 62=312. 360-312=48
Answer:
90%
Step-by-step explanation:
Is means equals and of means multiply
135 = P * 150
Divide each side by 150
135/150 = 150P/150
.9 =P
Change this to percent form by multiplying by 100%
.9*100%
90%
Answer:
Step-by-step explanation:
Find the slope of the line AB.
<u>The slope:</u>
- m = (11 - 9)/(11 - 7) = 2/4 = 1/2
Since the altitude is perpendicular to AB, it has a slope of -2.
The line with the slope of -2 and passes through point C(6, 16).
<u>Use point-slope equation to find the line:</u>
- y - 16 = -2(x - 6)
- y - 16 = -2x + 12
- y + 2x = 16 + 12
- 2x + y = 28
A = 2, B = 1, C = 28
