Answer:
Step-by-step explanation:
The antiderivative of the function is the same as the integral. To find the integral or antiderivative, reverse the process of differentiation method. Currently the function has degree 1. Through integration we increase the degree of each term by 1 and divide by the degree.
Thus 35 - 9x becomes . We add a constant C for any possible constant that was eliminated during differentiation.
Answer:
Surface area of pyramid with base equilateral triangle is square inches
Step-by-step explanation:
Recall the following result:
The total surface area(S) of a regular pyramid is given by,
...... (1)
Here, p represents the perimeter of the base , the slant height and B the base area of the pyramid.
From the given information:
Side of equilateral triangle = 20 inches
Slant height of the pyramid() = 13 inches.
First find the perimeter and Area of the base pyramid.
Perimeter of equilateral triangle(p) =
=
Area of equilateral triangle(B) =
= square inches.
Substitute the above values in equation (1) as shown below:
square inches
Hence, the surface area of pyramid with base equilateral triangle is square inches.
