Answer:
She needs 301.8 in² of tissue paper.
Step-by-step explanation:
In order to calculate the amount of tissue paper she needs to make 21 hats, we need to find the area of each hat and multiply it by the total number of hats she wants to make.
Since the Vietnamese conical hats are hollow and don't have a base, we need to find the area of the it's lateral walls, this is given by the following expression:
lateral area = pi*r*l
r = d/2 = 16/2 = 8 in
We were given the height, but we need the slant height, therefore:
l = sqrt(r² + h²) = sqrt(8² + 9²) = sqrt(64 + 81) = sqrt(145) = 12.041 in
Then the lateral area is:
lateral area = pi*8*12.0141 = 301.8 in²
She needs 301.8 in² of tissue paper.
Answer:
Not sure what the question is but if you're looking for who runs the most in a second I can give you that
Emily: 11 feet per second
Will: 9.66 feet per second
Stephanie: 13.27 feet per second
Liz: 8.98 feet per second
Based off this info, Stephanie runs the fastest per second
Remark
What this is telling you to do is put 3x + 3 in the question wherever there was an x to start with.
Solution
f(x) = -3x + 4
f(3x + 3) = - 3(3x + 3) + 4
f(3x + 3) = -3*3x + (-3)*(3) + 4
f(3x + 3) = - 9x - 9 + 4
f(3x + 3) = -9x - 5 <<<<< Answer
Considering the graph of the cube root parent function, it is found that the correct statement is given by:
D. It is always increasing.
<h3>When a function is increasing?</h3>
A function is increasing when the vertical axis of the graph gets higher as we move the horizontal axis from left to right.
In this problem, the above statement is true for the entire function, hence option D is correct.
