Answer:
x = 2Step-by-step explanation:
Given parallelogram ABCD with diagonals AC and BD intersect at point E, then;
AE = CE and BE = DE
Given;
AE =2x, BE = y +10, CE =x+2 and DE = 4y - 8.
Recall that AE = CE
2x = x+2
2x - x = 2
x = 2
Hence the value of x is 2

Answer:
[tex]\mathbf{v}(\pi/4)=-3\mathbf{i}+3\mathbf{j}+3 \mathbf{k}[/tex]
Step-by-step explanation:
Instantaneous Velocity
Given r(t) as the vector function of the position for time t, the instantaneous velocity is computed as:
[tex]\mathbf{v}=\frac{d\mathbf{r}}{dt}=\mathbf{r}'(t)[/tex]
We are given:
[tex]\mathbf{r}=\sin^2(3t)\mathbf{i}+3t\mathbf{j}-\cos^2(3t)\mathbf{k}[/tex]
Thus:
[tex]\mathbf{v}(t)=\mathbf{r}'(t)=[\sin^2(3t)\mathbf{i}+3t\mathbf{j}-\cos^2(3t)\mathbf{k}]'[/tex]
Computing the derivative:
[tex]\mathbf{v}(t)=2\sin(3t)\cos(3t)(3)\mathbf{i}+3\mathbf{j}+2\cos(3t)\sin(3t)(3)\mathbf{k}[/tex]
[tex]\mathbf{v}(t)=6\sin(3t)\cos(3t)\mathbf{i}+3\mathbf{j}+6\cos(3t)\sin(3t)\mathbf{k}[/tex]
Evaluating for t=π/4:
[tex]\mathbf{v}(\pi/4)=6\sin(3\pi/4)\cos(3\pi/4)\mathbf{i}+3\mathbf{j}+6\cos(3\pi/4)\sin(3\pi/4) \mathbf{k}[/tex]
[tex]\mathbf{v}(\pi/4)=6(\sqrt{2}/2)(-\sqrt{2}/2)\mathbf{i}+3\mathbf{j}+6(-\sqrt{2}/2))(\sqrt{2}/2)) \mathbf{k}[/tex]
[tex]\mathbf{v}(\pi/4)=-3\mathbf{i}+3\mathbf{j}-3 \mathbf{k}[/tex]

In a survey, 15 high school students said they could drive and 15 said they could not. Out of 60 college students surveyed, 30 said they could drive. Micah concluded that if someone is in college, that means the person is more likely to drive. Is Micah’s conclusion correct? Explain
Answer:
No. 30/60 and 15/30 is not overwhelming.
Step-by-step explanation:
Half of the students said they could drive. This is not more likely it's just half and half.
Answer:
No, Micah is not correct. Since there are equal numbers of people in each group who drive and who do not drive, the relative frequency for each is 50%. Because the relative frequencies are the same, there is no association between the variables.

Find the slope using (-19,12) and (-9,1)
Answer:
Slope = -13/10
Step-by-step explanation:
In order to find a slope of an equation, you must use the equation for a slope:
Slope = (y2 - y1) / (x2 - x1)
Use the provided coordinates in order to plug in the x and y values:
(-19, 12)
(-9, 1)
y2 = 12
y1 = 1
x2 = -19
x1 = -9
( 12 - 1) / (-19 - -9) = (13) / (-19 + 9) = 13 / -10 = -13/10

Recall some properites of exponentiation:
[tex]a^b\times a^c=a^{b+c}[/tex]
[tex]\left(a^b\right)^c=a^{b\times c}[/tex]
So for
(-2 x ² y ⁻¹) ⁻² (5 x ³ y) ²
first distribute the outermost exponents across each product:
((-2)⁻² (x ²)⁻² (y ⁻¹)⁻²) (5² (x ³)² y ²)
Simplify the powers using the multiplication property (the second one listed above) of exponents:
((-2)⁻² x ⁻⁴ y ²) (5² x ⁶ y ²)
Combine powers of the same terms using the addition property (the first one):
(-2)⁻² 5² x ⁻⁴⁺⁶ y ²⁺²
(-2)⁻² 5² x ² y ⁴
Finally, simplify the coefficient:
(-2)⁻² = 1 / (-2)² = 1/4
5² = 25
So you end up with
25/4 x ² y ⁴

Given f(x)=
7(3 – x), what is the value of f(-2)
Answer:
35
Step-by-step explanation:
Substitute (-2) in place of x
f(x) = 7(3-(-2)) = 7(3+2) = 7 (5) = 7 * 5 =35
What is a system of equations for the following situation? A group of 12 people went to see a movie. The cost to go to the movie is $10 for an adult and $6 for a child. The total cost for the group was $100.
Answer:
the second option
Step-by-step explanation:
since 12 people went in total, adults plus children would equal this value.
Together, they all paid 100 dollars. Therefore, since adults are 10 dollars and children are 6, multiplying these charges by the amount that showed up will give you 100 dollars.

y = 6x -24
y = -2x
Answer: x = 3, y = -6
Step-by-step explanation:
Substitute the y into the equation to get -2x=6x-24
8x=24 so x = 3. Then plug x=3 into the second equation to get y = -6

In 2004 the gross world product, W, (total output in goods and services) was 54.7 trillion dollars and growing at a continuous rate of 3.8% per year.
Required:
a. Write a formula for W, the GWP (in trillions of dollars), as a function of years, t, since 2004.
b. Estimate the value of t when the GWP is predicted to reach 85 trillion dollars
Answer:
W = 54.7*e^0.038t
11.6 years
Step-by-step explanation:
Given that :
Initial value = 54.7 trillion dollars
Continuous Growth rate (r) = 3.8% = 0.038
Using the exponential growth model formula :
W = P0*e^kt
Where ;
y = final amount ; P0 = initial value ; t = time ; k = growth rate constant
W = 54.7*e^0.038t
Value of t when W = 85 trillion
W = 85
85 = 54.7*e^0.038t
85 / 54.7 = e^0.038t
1.5539305 = e^0.038t
Take In of both sides
0.4407875 = 0.038t
Divide both sides by 0.038
t = 11.599672
t = 11.6 years
