Resolve the integral from 0 to 6 of xe^x with respect to x.
Answer:
[tex]\int\limits^6_0 {xe^{x} } \, dx = 4e^5 +1[/tex]
Step-by-step explanation:
Step(i):-
Given
[tex]I = \int\limits^6_0 {xe^{x} } \, dx[/tex]
By using UV formula
[tex]\int\limits {UV} \, dx = U\int\limits {v} \, dx - ( \int\limits {(U^{l} } \int\limits {v} \, dx \, )dx[/tex]
Now , we take
U = x and V = e ˣ
U¹ = 1 and [tex]\int\limits {e^{x} } \, dx = e^{x}[/tex]
Step(ii):-
[tex]\int\limits {xe^x} \, dx = x\int\limits {e^x} \, dx - ( \int\limits {(1) } \int\limits {e^x} \, dx \, )dx[/tex]
= x e ˣ - [tex]\int\limits {e^x} \, dx[/tex]
= x e ˣ - e ˣ + C
[tex]\int\limits^6_0 {xe^{x} } \, dx =( e^ x ( x -1) )_{0} ^{6}[/tex]
= e⁵ (5-1) - (e⁰ (0-1)
= 4 e⁵ + 1
Final answer:-
[tex]\int\limits^6_0 {xe^{x} } \, dx = 4e^5 +1[/tex]

2) The notebook shows the money Leo earned and spent on his first day selling strawberries at the Farmers' Market. A positive number represents money earned. A negative number represents money spent. Leo wants to find his profit for the first day. What is Leo's profit for the first day?
Answer: The answer is five
Step-by-step explanation:
Leo's profit for the first day is $5.
Given that,
The money earned is $8.And, the money spent is -$3.Based on the above information, the calculation is as follows:
= $8 - $3
= $5
Therefore we can conclude that Leo's profit for the first day is $5.

The sum of two numbers is 79,and their difference is 33
Answer: infinite answers, jk there is like a lot tho
Step-by-step explanation: The sum of x and y is 79. In other words, x plus y equals 79 and can be written as equation A:
x + y = 79
The difference between x and y is 23. In other words, x minus y equals 23 and can be written as equation B:
x - y = 23
Now solve equation B for x to get the revised equation B:
x - y = 23
x = 23 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 79
23 + y + y = 79
23 + 2y = 79
2y = 56
y = 28
Now we know y is 28. Which means that we can substitute y for 28 in equation A and solve for x:
x + y = 79
x + 28 = 79
X = 51
Summary: The sum of the two numbers is 79 and their difference is 23. What are the two numbers? Answer: 51 and 28 as proven here:
Sum: 51 + 28 = 79
Difference: 51 - 28 = 23

Evaluate the expression for m=4 n=5 p=-2
m^-n
Answer: 1/1024
Step-by-step explanation:
m^-n=4^(-5)
=1/(4^5)
=1/1024
Answer:
Equation :---
[tex] {m}^{ - n} [/tex]
where m=4, n=5 and p=-2
[tex] {4}^{ - 5} = \frac{1}{ {4}^{5} } = \frac{1}{1024} \\ [/tex]
1/1024 is the right answer.The perimeter of a square is 80 - 64y units.Which expression can be used to show the side length of one side of the square.
A. 16(5-4y).Each side measures 5-4y units
B. 16y(5-4y) Each side measures 5-4 y units
C. 4(20-16y)Each side measures 20-16y units
D 4y(20-16)Each side measures 20-16 units
Answer A. 16(5-4y).Each side measures 5-4y units
Step-by-step explanation:
Answer:
Option C is correct
4(20-16y) each side measures 20-16y units
Step-by-step explanation:
The distributive property says that:
The perimeter(P) of a square is given by:
.....[1]
As per the statement:
The perimeter of a square is 80-64y units
we can write this as:
Apply the distributive property we have;
⇒P = 4(20-16y)
On comparing with [1] we have;
Each Side length = 20-16y units
Therefore, an expression can be used to show the side length of one side of the square is, 4(20-16y) each side measures 20-16y units

A basket contains 20 green apples and
30 red apples. If a piece of fruit is
selected at random from the basket, what
is the probability that it will not be a red
apple?
A:2/5 B:3/5 C:2/3
Answer: 40% , A:2/5
Step-by-step explanation:
// mean comment btw
-There is 50 apples //you know for 20+30
The probability of getting a red apple is 30/50 or 60/100
Next you can either do 100-60 to find out the percentage on not getting a red apple is or find the probability of getting a green apple which is 20/50 or 40/100
Now simplify 20/50 is equivalent to 2/5 thus the answer is A
Joe's age Is x years. Match the descriptions of the ages of Angela, Bruce, Callie, and Deshawn with the expressions in terms of Joe's age, x. +4 41+2 +3 40-3 Bruce's age is 4 years more than half Joe's age. Callie's age is 3 years less than 4 times Joe's age. Angela's age is 4 years more than twice Joe's age. Deshawn's age is 3 years more than half Joe's age.
Answer: I am pretty sure its what I said
Bruce: x/2 + 4
Angela: 4x + 2
Callie: 4x - 3
Deshawn: x/2 + 3

Answer:
[tex]\huge\boxed{y=-2x+5}[/tex]
Step-by-step explanation:
In order to solve for the equation of the line, we need to note a couple of things.
A) If a line is parallel to another, they will both have the same slope B) We can substitute x and y values into the equation to find unknown values.Since the line is parallel to the equation [tex]y = -2x[/tex], we know that the slope is -2.
Equations will be in the form [tex]y = mx+b[/tex], m being the slope, and b being the y-intercept. Since we know the slope, we can substitute it into the equation.
[tex]y = -2x+b[/tex]
Additionally, we know one of the points it passes through. Therefore, we can also substitute this into the equation and find the value of b (y-intercept).
[tex]-3 = -2 \cdot 4 + b[/tex]
Solve for b:
[tex]-3 = -8 + b[/tex] [tex]b = -3+8[/tex] [tex]b = 5[/tex]Now we know the slope and the y-intercept, which is all we need to create our equation.
[tex]y = -2x+5[/tex]
Hope this helped!

Answer:
16. y=-5x-20; 17. y=6x+18, or factored y=6(x+3)
Step-by-step explanation:
Your slope is -5
y=-5x+b, solve for b by pluging the point (-3,-5) in for x and y
-5=-5(-3)+b, solve for b
-20=b, now rewrite the equation
y=-5x-20
Your slope is 6
y=-5x+b, solve for b by pluging the point (-3,-0) in for x and y
0=6(-3)+b, solve for b
18=b, now rewrite the equation
y=6x+18, or factored y=6(x+3)
8x-2y=1

Say you a have a bag of 20 marbles and 7 of those marbles are blue. Find the probability that if you draw one marble, it is NOT blue.
Question 3 options:
0.05
0.35
0.65
0.14
Step-by-step explanation:
7 out of 20 marbles are blue
1-7/20= 13 out of 20 marbles not blue
13/20=0.65
Answer:
C) 0.65 (65%)
Step-by-step explanation:
Divide: 13 ÷ 20
This is the chance that drawing one marble, the color will not be blue.
