There is NO elementary function that gives the antiderivative of e^(-x^2)
This expression in fact is called the Gaussian integral, since it gives the Gaussian bell curve.
Its integration is done by numerical methods, it is widely used in Statistics, and there are tables to calculate definite integrals associated with probability distributions.

Answer:
[tex]Area = 6.5 * 10^3cm^2[/tex] or [tex]Area = 6.5E3\ cm^2[/tex]
Step-by-step explanation:
Given
[tex]Width = 1.5 * 10^2cm[/tex]
[tex]Length = 4.3 * 10^1cm[/tex]
Required
Determine the Area
The base area is calculated as:
[tex]Area = Length * Width[/tex]
[tex]Area = 1.5 * 10^2cm * 4.3 * 10^1 cm[/tex]
Reorder the expression
[tex]Area = 1.5 * 4.3 * 10^1 cm* 10^2cm[/tex]
[tex]Area = 6.45 * 10^1 cm* 10^2cm[/tex]
Apply law of indices
[tex]Area = 6.45 * 10^{1+2}cm^2[/tex]
[tex]Area = 6.45 * 10^3cm^2[/tex]
Approximate
[tex]Area = 6.5 * 10^3cm^2[/tex]
or
[tex]Area = 6.5E3\ cm^2[/tex]

Today the price of a Jeep is $25,000. In 1970, the price was $5,000. What's the price relative?
Answers
Answer:
$500
Step-by-step explanation:
Today the price of a Jeep is $25,000.
In 1970, the price was $5,000.
We need to find the relative price. It can be calculated as follows :
[tex]P=\dfrac{25000}{5000}\times 100\\\\P=\$500[/tex]
So, the relative price is $500.

You are going to an amusement park over Spring Break. The cost of admission to enter the park is $30 and the rides are an additional $6 each. If your parents give you $100 to spend at the amusement park, what is the maximum number of rides you can go on? Write an inequality to show the maximum number of rides you can go on.
Answers
Answer:
30+6x ≤ 100 (inequality)
The maximum amount of rides is 11 rides
Step-by-step explanation:
So first the admission fee is 30
Each ride is 6
So since you can go on any amount of rides, its unknown so (x)
You only have a 100 dollars and you can’t go over but you can go lower
so 30+6x≤100
If you solve it
x≤11
So 11 rides

{1, 3, 5}
{2, 4}
Answers
Answer:
A∩B={7,9}
Option A is correct option.
Step-by-step explanation:
We are given:
A = {3, 5, 7, 9} and B = {1, 2, 4, 6, 7, 9}
and we need to find A intersects with B i.e. A∩B
We find A intersects with B, we will consider only those terms that are common in both A and B
So,
A∩B= {3, 5, 7, 9} ∩ {1, 2, 4, 6, 7, 9}
As 7 and 9 are only common in both A an B
A∩B={7,9}
So, we get: A∩B={7,9}
Option A is correct option.

For what value of the number k is the following function differentiable at x=2
f(x) = {2x + 1 if x<2
k x=2
3x-1 x>2}
Answers
Answer:
For f(x) to be differentiable at 2, k = 5.
Step-by-step explanation:
For f(x) to be differentiable at x = 2, f(x) has to be continuous at 2.
For f(x) to be continuous at 2, the limit of f(2 – h) = f(2) = f(2 + h) as h tends to 0.
Now,
f(2 – h) = 2(2 – h) + 1 = 4 – 2h + 1 = 5 – 2h.
As h tends to 0, lim (5 – 2h) = 5
Also
f(2 + h) = 3(2 + h) – 1 = 6 + 3h – 1 = 5 + 3h
As h tends to 0, lim (5 + 3h) = 5.
So, for f(2) to be continuous k = 5

Q2:The price of a pair of shoes increases from $68 to $81. What is the percent increase to the nearest percent?
The percent increase is ? %.
Answers
Answer:
Step-by-step explanation:
23 x .565 = 12.995
12.995 rounded is 13.
So if the answer is .565, and you need to round to the nearest percent, it would be 57%.
Answer:
Step-by-step explanation:
1) Decreased students = 23 -13 = 10
Decreased percentage = [tex]\frac{10}{23}*100[/tex]
[tex]= \frac{1000}{23}\\\\= 43.47[/tex]
= 43%
2) Increased amount = 81 - 68 = $ 13
Increased percentage = [tex]\frac{13}{68}*100[/tex]
[tex]= \frac{1300}{68}\\\\= 19.11[/tex]
= 19%

Answer:
B. 25√3
Step-by-step explanation:
Use trigonometric ratio formula to find the length and width of the rectangle
Thus:
✔️Length of diagonal:
Reference angle = 30°
Hypotenuse = 10
Let length of rectangle = x = adjacent side
Therefore:
Cos 30° = x/10
10*cos 30 = x
10*√3/2 = x (cos 30 = √3/2)
5√3 = x
x = length of rectangle = 5√3
✔️Width of diagonal:
Reference angle = 30°
Hypotenuse = 10
Let width of rectangle = y = opposite side
Therefore:
Sin 30° = y/10
10*sin 30 = y
10*½ = y (sin 30 = 1/2)
5 = y
y = width of rectangle = 5
✔️Area of rectangle = length * width = 5√3 * 5 = 25√3
