How do you do this question?
Answer:
(8√2) / 15
Step-by-step explanation:
A curve bounded by the y-axis is represented by in terms of dy;
[tex]\int \:x\:dt[/tex]
When the curve crosses the y-axis, x will be 0. In this case x is the function of t, so we have to solve for x(t) = 0;
0 = t^2 + 2t --- (1)
Solution(s) => t = 0, t = 2
dy = (1/2 * 1/√t)dt --- (2)
Our solutions (0, 2) are our limits. The area of the curve is in the form [tex]A\:=\:\int _b^a\:f\left(t\right)g'\left(t\right)dt[/tex] , so now let's introduce the limits of integration, x(t) and dy/dt. Remember, dy/dt = (1/2 * 1/√t) (second equation). 1/2 * 1/√t can be rewritten as 1/2 * t^(-1/2)....
[tex]A\:=\:\int _2^0\:\left(t^2-2t\right)\left(\frac{1}{2}t^{-\frac{1}{2}}\right)dt\\\\= \int _2^0\:\left(\frac{1}{2}t^{\frac{3}{2}}-t^{\frac{1}{2}}\right)dt\\\\= \left[\frac{t^{\frac{5}{2}}}{5}-\frac{2t^{\frac{3}{2}}}{3}\right]_2^0\\\\= 0\:-\:\left(\frac{4\sqrt{2}}{5}-\frac{4\sqrt{2}}{3}\right)\\\\= \frac{8\sqrt{2}}{15}[/tex]
Your solution is 8√2 / 15
-3x + 8 = 17 and 1 + 4x = -15
Answer:
1) x= -3
2) x=-4
Step-by-step explanation:
The first equation is :
-3x+8=17
solving for x
-3x=17-8 ------------by collecting like terms
-3x=9
Divide both sides by -3
-3x/-3=9/-3
x= -3
In the second equation
1+4x= -15
solving for x
4x=-15-1
4x = -16
x=-16/4
x= -4
Write the slope-intercept form of the equation of the line
2x + 3y = 18
Answer:
y=-2/3x+18
Step-by-step explanation:
Slope intercept form equals y=mx+b
Step 1 move 2x to the other side. 3y=-2x+18
Step 2 divide by 3. y=-2/3x+18
Solve for t.
-t = 9(t-10)
pls help
Step-by-step explanation:
-t = 9(t-10)
-t = 9t - 90
90 = 9t + t
90 = 10t
90 ÷ 10 = t
9 = t

Answer:
Dustin Earns $14,000 in a year but in the question, we are given the salary of a month
Monthly salary of dustin:
14000 / 12 = $1,166 (approx)
Hence,
The actual monthly salary of Dustin is $1166, excluding the commissions
For a specific month, the salary of Dustin including the commissions is $2,400
Money earned in commissions:
Salary earned - Actual monthly salary
2400 - 1166 = $1,234
We are given the sales of Dustin for that specific month = $ 18,000
Hence, Dustin Earned a commission of $1,234 for sales of $18,000
Commission rate of Dustin:
Commission Earned * 100 / Sales made
1234 * 100 / 18000
6.856 %
Therefore, the commission rate of Dustin is 6.856%

Answer:
y-intercept: (0, 5); slope: 1/4
Step-by-step explanation:
The slope (m) is found from ...
m = (y2 -y1)/(x2 -x1)
Using the first two points in the table, this is ...
m = (8 -6)/(12 -4) = 2/8 = 1/4 . . . . . eliminates choices A and C
__
Then, the point-slope form of the equation of the line can be written as ...
y -y1 = m(x -x1)
y -6 = (1/4)(x -4) . . . fill in known values
y = 1/4x -1 +6 . . . . . add 6
y = 1/4x +5
Then the value of y when x=0 is ...
y = 0 +5 = 5
So, the y-intercept is (0, 5) and the slope is 1/4, matching the last choice.

Some the equation 4y-6x=12 for y.
Answer:
y = 3 + 1.5x
Step-by-step explanation:
4y = 12 + 6x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Divide each side by '4'.
y = 3 + 1.5x
Simplifying
y = 3 + 1.5x
Answer:
y = 3/2x + 3
Step-by-step explanation:
Given :
4y - 6x = 12To Do :-
To solve out for y .Solution :-
The given equation is ,
⇒ 4y - 6x = 12
⇒ 4y = 6x + 12
⇒ y = ( 6x + 12 )/4
⇒ y = 3/2x + 3

4p + 2р - Зр
Oi mans needs help
Answer:
3p
Step-by-step explanation:
4p + 2р - Зр
Combine like terms
6p -3p
3p
Think of 4p as having 4 pizzas
Adding on 2 more pizzas gets you 4p+2p = 6p
So we have 6 pizzas now.
Then we subtract off 3 pizzas
6p-3p = 3p
Leaving us with 3 left when everything is said and done
So,
4p + 2p - 3p = 6p-3p = 3p

making x dozen cookies. How much does it cost Mr. Thompson to make 25
dozen cookies? {Write an equation.} *and also ( solve and equation).
Answer:
Step-by-step explanation:
3x - 4y = 13 (1)
2x + y = 5 (2)
——————
3x - 4y = 13
4(2x + y = 5) (2) times 4
——————-
3x - 4y = 13
8x + 4y = 20
——————-
11x = 33
x = 33/11
x = 3
Plug x = 3 in (2):
2(3) + y = 5
6 + y = 5
y = 5-6
y = -1
Thus, x = 3 and y = -1
Robert earned $10, which was 4 less than twice what Eric earned , How much money did Eric earn?
Answer:
Eric's earning is $7
Step-by-step explanation:
Given
Represent Robert's earnings with R and Eric's with E.
[tex]R = 10\\R = 2E - 4[/tex]
Required
What is the value of E?
Substitute 10 for R in the second equation.
[tex]10 = 2E - 4[/tex]
Solve for 2E
[tex]2E = 10 + 4[/tex]
[tex]2E = 14[/tex]

Answer:
The binomial probability distribution is shown below.
Step-by-step explanation:
The probability mass function of X is:
[tex]P(X=x)={n\choose x}p^{x}(1-p)^{n-x};x=0,1,2,3..[/tex]
It is provided that n = 6 and p = 0.25.
Construct a binomial probability distribution with the given parameters as follows:
X P (X = x)
0 [tex]P(X=0)={6\choose 0}(0.25)^{0}(1-0.25)^{6-0}= 0.1780[/tex]
1 [tex]P(X=1)={6\choose 1}(0.25)^{1}(1-0.25)^{6-1}= 0.3560[/tex]
2 [tex]P(X=2)={6\choose 2}(0.25)^{2}(1-0.25)^{6-2}= 0.2966[/tex]
3 [tex]P(X=3)={6\choose 3}(0.25)^{3}(1-0.25)^{6-3}= 0.1318[/tex]
4 [tex]P(X=4)={6\choose 4}(0.25)^{4}(1-0.25)^{6-4}= 0.0330[/tex]
5 [tex]P(X=5)={6\choose 5}(0.25)^{5}(1-0.25)^{6-5}= 0.0044[/tex]
6 [tex]P(X=6)={6\choose 6}(0.25)^{6}(1-0.25)^{6-6}= 0.0002[/tex]
Compute the mean and standard deviation as follows:
[tex]\mu=np=6\times0.25=1.50\\\\\sigma=\sqrt{np(1-p)}=\sqrt{6\times 0.25\times (1-0.25)}=1.0607[/tex]
Binomial probability distribution was constructed, and the mean and standard deviation comes to be 1.5 and 1.061 respectively.
As we know that binomial probability distribution is given by
[tex]P(x) = ^nC_xp^x(1-p)^{n-x}[/tex]
What is binomial distribution?The binomial distribution is a probability distribution that depicts the likelihood that a value will take one of two independent values under a given set of parameters.
Given n=6 & p=0.25
[tex]P(0) = ^6C_0(0.25)^0(1-0.25)^{6-0}[/tex] = 0.1780
[tex]P(1) = ^6C_1(0.25)^1(1-0.25)^{6-1}[/tex]=0.3560
[tex]P(2) = ^6C_2(0.25)^2(1-0.25)^{6-2}[/tex] = 0.2966
[tex]P(0) = ^6C_3(0.25)^3(1-0.25)^{6-3}[/tex] =0.1318
[tex]P(0) = ^6C_4(0.25)^4(1-0.25)^{6-4}[/tex]=0.0330
[tex]P(5) = ^6C_5(0.25)^5(1-0.25)^{6-5}[/tex]=0.0044
[tex]P(6) = ^6C_6(0.25)^6(1-0.25)^{6-6}[/tex]= 0.0002
Mean = np
Mean = 6*0.25
Mean = 1.5
Standard deviation σ = [tex]\sqrt{np(1-p)}[/tex]
σ = [tex]\sqrt{6*0.25(1-0.25)}[/tex]
σ = 1.061
Hence, binomial probability distribution was constructed, and the mean and standard deviation comes to be 1.5 and 1.061 respectively.

How do you simplify the expression (s+t)3
Answer:
3s + 3t
Step-by-step explanation:
To simplify this expression, all you need to do is distribute the 3, which means you basically multiply whatever is in the parentheses by 3:
(s + t) * 3 =
3s + 3t
And that is the simplified form for this expression.

Find the equation of the line with slope 2/5 and y-intercept (0,−2).
Answer:
[tex]\boxed {\tt y=\frac{2}{5}x-2}[/tex]
Step-by-step explanation:
If the slope and y-intercept is known, the equation of a line can be written using slope-intercept form.
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept.
We know that the slope is 2/5.
The y-intercept is (0,-2). For this form, we only need the y-coordinate, which is -2 in this case. Therefore, we can say the y-intercept is -2.
[tex]m=2/5 \\b= -2 \\[/tex]
Substitute the values into the formula.
[tex]y=2/5x+ (-2)[/tex]
[tex]y=2/5x-2[/tex]
The equation of the line is y=2/5x-2
