The Riemann sum, the limit as the maximum of delta x sub i goes to infinity of the summation from i equals 1 to n of f of the quantity x star sub i times delta x sub i , is equivalent to the limit as n goes to infinity of the summation from i equals 1 to n of f of the quantity a plus i times delta x, times delta x with delta x equals the quotient of the quantity b minus a and n. Write the integral that produces the same value as the limit as n goes to infinity of the summation from i equals 1 to n of the product of the quantity 2 plus 3 times i over n and 3 over n.

Answer:

yes , keiko is correct.

sin^(-1)x = -sin^1

Answer:

Keiko is wrong

Step-by-step explanation:

Keiko is incorrect

When n is positive, 1^n will always be 1

but........ (-1)^n will not always be -1

This is because there are parenthesis around -1

So n is even, then it will be 1 not -1

For example, n = 4

You will do -1 * -1 * -1 * -1 which is 1 not -1

but if n = 3

You will do -1 * -1 * -1 which is -1

Therefore, the second statement is incorrect resulting in Keiko being wrong

Answers

Answer:

ur answer should be C. But I'm not really sure..

The table in which y is a linear function of x is; Choice C

Linear functions

According to the question;

We are required to identify in what table y is a linear function of x.

The slope of a linear function is always constant.

Hence, By observing the table in Choice C;

Slope = (8-6)/(0-(-1)) = (10-8)/(1-0) = 2.

Hence, since slope of the function is constant, the required table is: Choice C.

Without calculating, predict whether the area of the rectangle will be greater or less than 25 square meters if the length is 5.25 meters.

Answers

Answer:

depends on the other side, so... maybe

Step-by-step explanation:

If you have a rectangle and you know one side is 5.25, then if the perpendicular side looks about the same length or longer, then the area of the rectangle is at least 25.

Imagine you have a rectangle with a known base of 5.25, then if the rectangle is at least as tall as it is wide, then the area is over 25.  If the rectangle is very close to a square then the area should be near 25, and if the rectangle is visually shorter than it is wide then the area is less than 25

(x-11)(x+4)=0

x= 11 or x= -4

Answer:

x = 11 or x = -4

Step-by-step explanation:

x^2 - 7x - 44 = 0

-11 + 4 = -7, -11 × 4 = -44

(x -11)(x + 4) = 0 or (x + 4)(x - 11) = 0 Both are same way: O
