Answer:
1276.19553 
Step-by-step explanation:
First, find height using Pythagoras thorem.
a=
a=15.61
Then use the formula to find the surface area of a cone.
π•12.5•(12.5+
)=1276.19553 
Answer:
Step-by-step explanation:
5x^3+8x-8x^2-5x^2+8x^3+7x
14x^3-14x^2+15x
Answer:
(0.5, 5.5)
Step-by-step explanation:
So we know that one point is (-4, 6) and the other point is (3, 5). Also we know that Diagonals of a rhombus intersect at their midpoints.
For that reason, the point is:
x = (3 -4)/2=0.5
y=(5+6)/2 = 5.5
Then, the response is: (0.5, 5.5)
Answer: The answer is given below.
Step-by-step explanation: We are given an equality involving logarithm and we are to show the implication of L.H.S. to R.H.S.
We will be using the following two properties of logarithm:

The proof is as follows:

Hence proved.
