Answer:

200.96 square feet

Step-by-step explanation:

SA = 2pi(r²) + 2pi(r)h

r = 2

pi = 3.14

h = 14

SA = 2(3.14)2² + 2(3.14)(2)14

SA = 6.28(4) + 6.28(2)14

SA = 25.12 + 175.84

SA = 200.96

Find the interquartile range for a data set having the five-number summary: 3.5, 10.4, 16, 21.7, 27.7
vlabodo [156]

Answer: 17.75

Step-by-step explanation:

The interquartile range(IQR) is the 3rd quartile - the 1st quartile.

How to get quartiles:

First get the median:

3.5, 10.4, 16, 21.7, 27.7

10.4, 16, 21.7

16

Then find the median of the first half of data(3.5, 10.4)

(3.5+10.4)/2 = 6.95

Then find the median of the last half of data(21.7, 27.7)

(21.7+27.7)/2 = 24.7

Then to get the IQR subtract 6.95 from 24.7 to get 17.75

12. Find the area lying above the x - axis and below the parabolic curve y = 4x - x2.
Margarita [4]
First we find the zeroes so we don't take the integral of negative bits

4x-x²
x(4-x)
zeroes at x=0 and x=4
it opens down
so the part we are interested in is the bit between x=0 and x=4

\int\limits^4_0 {4x-x^2} \, dx =[2x^2- \frac{1}{3}x^3]^4_0=(32- \frac{64}{3})-(0)=  10.6666666666 or aout 10 and 2/3

Answer:

41

Step-by-step explanation:

The question is a little vague, but I’m assuming you meant to say x + y. If that’s the case just do 24 + 17, which is 41.

Can someone please answer number 5?
Free_Kalibri [48]

Answer:

x=13

Step-by-step explanation:

since they are vertical angles, they equal each other so set both angles to have them equal each other to find x

8x - 12 = 6x + 14

Add 12 on both sides

8x = 6x  + 26

Subtract tax from both sides

2x = 26

Divide by 2 for both sides

x = 13
