Answer:
117
Step-by-step explanation:
90×.30 or 30%=27
27+90=117
Answer:
a. Triangular prism , b. 157.5cm squared , c. 369cm ,d. 405 cm cubic
Step-by-step explanation:
b. I assume lateral meabs the area which is visible ( exclude dotted lines)
c. sum of areas of all 5 shapes used to make the triangular prism ( L×W ) + l×w +l×w + 1/2×bh +1/2×bh
d. volume = AREA OF CROSS SECTION(which is a triangle) ×LENGHTH or Height(6cm)
Answer:
Step-by-step explanation:
This is most easily solved with calculus, believe it or not. It is way more direct and to the point, with a whole lot less math!
The position function is given. The velocity function is the first derivative of the position, so if we find the velocity function and set it equal to 0, we can solve for the amount of time it takes for the rocket to reach its max height. Remember from physics that at the top of a parabolic path, the velocity is 0.
If:
, then the velocity function, the first derivative is:
v(t) = -32t + 112 and solve for t:
-112 = -32t so
t = 3.5 seconds. Now we know how long it takes to get to the max height, we just need to find out what the max height is.
Go back to the position function and sub in 3.5 for t to tell us that position of the rocket at 3.5 seconds, which translates to the max height:
and
s(3.5) = 206 feet. I imagine that your answer, if you had to choose one from the list, would be 200 feet, rounded a lot.
Answer:
The constant is 3
Step-by-step explanation:
To the answer, you divide y/x.
15/5 = 3
9/3 = 3
6/2 = 3
1.5/ 0.5 = 3
