Answer:
C.
Step-by-step explanation:
5 is not less than 2
5 is not greater than 9 or 42
With this function you are given 2 x's and all we have to do is plug those X's into the function so
f(-1)=4*7^-1
7^-1 is 1/7
times 4 = 4/7
f(2)=4*7^2
7^2=49 *4 = 196
Answer:
78.95cm^2
Step-by-step explanation:
The equation for a cylinder is rπ^2 · h
2π²·4≈78.95
The new matrix that is formed by the 3A + B is given below. Then the value of x is 102.
<h3>What is the matrix?</h3>
A matrix is a specific arrangement of items, particularly numbers. A matrix is a row-and-column mathematical structure. The 
element in a matrix, such as M, refers to the i-th row and j-th column element.
The matrices are given below.
Then the new matrix is given as 3A + B. Then we have
