Answer:
43
Step-by-step explanation:
Estimate the area under the curve f(x) = 16 - x^2 from x = 0 to x = 3 by using three inscribed (under the curve) rectangles
First we find out the width of the rectangle
Δx=b−a/n, a= 0 and b= 3, n= 3
so Δx= 1
Divide the interval [0,3] into 3 sub intervals of width=1
[0,1] [1,2] [2,3]
Now we plug in end point and evaluate the function
We take left endpoints

f(0) = 16 - 0^2=16
f(1) = 16 - 1^2= 15
f(2) = 16 - 2^2= 12
Now sum = Δx(f(0) + f(1)+f(2))
= 1 (16+15+12)= 43
Answer: 18
Step-by-step explanation:
The question is asked to know 30% of 60, we get
60 x 30% = 60 x 0.3 = 18
1) √72z² = 6z √2 B.
2 * 6 * 6 = 72
2) C. √6
3 * 3 √6 - 4 * 2 √6 = 9√6 - 8√6 = √6

Answer:
1/1560
Step-by-step explanation:
The chance of you winning is 1/40, since there are 40 students and you are one of those students. Since, you cannot win again once you win once, you are eliminated. This leaves us with 39 people left. The chances of your friend being chosen out of the 39 people left is 1/39. Now you must multiply 1/40 and 1/39. After multiplying, you get 1/1560.
