Answer:
Choice D, 20 inches.
Step-by-step explanation:
The Pythaogorean theorem tells us that the hypotenuse of a triangle, c, can be found by taking: c = . In this case, a = 3 and b = 4. So:
c =
c =
c =
c =
c = 5
The sides of a rhombus are all equal. Given that one side is equal to 5, we can simply multiply 5 by 4 to get 20. The perimeter is 20 inches.

Answer:
- 320 m after 8 seconds
- 5.6 seconds, 10.4 seconds to height of 290 m
Step-by-step explanation:
To find the height at 8 seconds, evaluate the formula for t=8.
S(t) = -5t^2 +80t
S(8) = -5(8^2) +80(8) = -320 +640 = 320
The height of the rocket is 320 meters 8 seconds after takeoff.
__
To find the time to 290 meters height, solve ...
S(t) = 290
290 = -5t^2 +80t
-58 = t^2 -16t . . . . . . . divide by -5
6 = t^2 -16t +64 . . . . . complete the square by adding 64
±√6 = t -8 . . . . . . . . . take the square root
t = 8 ±√6 ≈ {5.551, 10.449}
The rocket is at 290 meters height after 5.6 seconds and again after 10.4 seconds.
Answer:
1
Step-by-step explanation:
The function f(x)=x+6*2 can be rewritten as f(x)=x+12
The average rate of change on the function f on [a,b] interval is the ratio of the changes :
We determine our substitute our interval values in the function:
Hence, the average rate of change is 1
Answer:
False
Step-by-step explanation:
2*2 =4, so if this were true 4*2 would equal 6. Since it doesn't, the answer is false.
I hope this helps :)
