Let f be a continuous function on the interval [a, b]. Determine if the following statement is true or false. The expression lim f(xi") ax may lead to different limits if we choose the x * to be the left endpoints instead of midpoints. ni=1 Choose the correct answer below. O A. The statement is true. Each sum will be smaller when picking a left endpoint, so the limit will be smaller. OB. The statement is false. Any sample point can be chosen within the interval without affecting the limit. O C. The statement is true. The value of the function at the left endpoint is not the same as the value at the midpoint of the interval D. The statement is false. The value of the function at the left endpoint is the same as the value at the midpoint of the interval. w Click to select your answer

Answers
Answer:
The correct answer is B.
Step-by-step explanation:
We have the expression:
[tex]\displaystyle \lim_{n\to\infty}\sum_{i=1}^{n}f(x_i\, ^\star)\Delta x[/tex]
In this case, B is the correct answer.
B states that any sample point can be chosen without affecting the limit.
This is a true statement. Regardless of which point we choose for our sample point, since n approaches infinity, we will have infinite partitions.
Hence, this will not affect the sum of our expression.
A and C are false because we have infinite partitions, so the statements cannot be true. D is not true simply because the left-hand values do not have to be the same as the midpoint-values depending on the behavior of the function for [a, b].

10 binder; 60% off; 6% tax
Answers
Answer:
I'm going to assume that the binder is $10, and that the tax is applied after the 60% off, in which case the answer is $4.24

10 * 10 = 100
6 * 10 = 60
10 - 6 = 4
6 / 25 = 0.24

(-1, 0), (0, -4), (1, -6) points are solutions of the given quadratic equation.
What is a quadratic equation?A quadratic equation is an equation where the variable has the highest power of 2.
Given equation is y = x² - 3x - 4
1. For (-4, 0), L.H.S = 0, R.HS = (- 4)² - 3(- 4) - 4 = 24.
Hence, (-4, 0) is not a solution of the given equation.
2. For (-1, 0), L.H.S = 0, R.HS = (- 1)² - 3(- 1) - 4 = 0.
Hence, (-1, 0) is a solution of the given equation.
3. For (0, -4), L.H.S = -4, R.HS = (0)² - 3( 0) - 4 = - 4
Hence, (0, -4) is a solution of the given equation.
4. For (1, -6), L.H.S = -6, R.HS = (1)² - 3(1) - 4 = -6.
Hence, (1, -6) is a solution of the given equation.
5. For (1, 0), L.H.S = 0, R.HS = (1)² - 3(1) - 4 = -6.
Hence, (1, 0) is not a solution of the given equation.
6. For (3, -7), L.H.S = -7, R.HS = (3)² - 3(3) - 4 = -4.
Hence, (3, -7) is not a solution of the given equation.

Annika's older cousin borrowed $800 to repair her car. she will pay off the loan after 2 years by paying back the principal plus 4.5% simple interest each year. How much will she spend in interest? How much will she pay back altogether?
Answers
Answer:
The equation below is provided:
$800 = principal amount borrowed/loaned
4.5% = interest per year
2 years = terms of payment
You need to know how much is the interest per year.
$800 * 4.5% = $36
Then, multiply the amount to the terms of payment to know the total amount of the interest to be paid.
$36 * 2 years = $72
The correct answer for the amount that Anika will spend for the interest is $72.

Find the y-intercept using the formula [ y = mx + b ].
y = 1/3x + b
-12 = 1/3(-24) + b
-12 = -8 + b
-4 = b
Use (18, 2) to see if the line passes through it
y = 1/3x - 4
2 = 1/3(18) - 4
2 = 6 - 4
2 = 2 TRUE
Thus, the line does pass through (18, 2).
Best of Luck!
the line does not pass trough the point (18, 2) that other line decreases and for it to passes through the point it would have to increases

Solve the inequality below.
-x + 5 < 7
Which of the following values of x DO NOT make the inequality true?
A. -1
B.- 3
C. 7
D. 5
Answers
Answer:
B: -3
Step-by-step explanation:
-(-3) + 5 < 7
3 + 5 <7
8 < 7 FALSE
Answer:
-3
Step-by-step explanation:
Solve for x in the inequality, to get x > -2 (see the image below if you want to know how to solve it). Then, we can substitute the numbers for x to see which ones DO NOT make the inequality true:
-1 > -2 This is true, because -1 is greater than -2
-3 > -2 This is false, because -3 is not greater than -2
7 > -2 This is true, because 7 is greater than -2
5 > -2 This is true, because 5 is greater than -2
So you can see that -3 is the number that DOES NOT make the inequality true. So therefore:
Answer: -3
Hope this helps! :)
