ABCD is a quadrilateral
calculate the value of x
Answer:
A. x = 18
B. Line AD and line BC are parallel.
Step-by-step explanation:
A. Determination of the value of x.
5x + 3x + 7x + 90 = 360 (sum of angles in quadrilateral.
15x + 90 = 360
Collect like terms
15x = 360 – 90
15x = 270
Divide both side by 15
x = 270/15
x = 18
B. Determination whether or not line AD will be parallel to line BC if drawn to scale.
We shall determine the various angle in the quadrilateral. This can be obtained as follow:
<A = 5x
x = 18
<A = 5(18)
<A = 90°
<B = 90°
<C = 7x
x = 18
<C = 7(18)
<C = 126°
<D = 3x
x = 18
<D = 3(18)
<D = 54°
Summary:
<A = 90°
<B = 90°
<C = 126°
<D = 54°
From the above illustration, we can see that <A and <B are equal (i.e 90°). Thus, line AB is a perpendicular bisector of line AD and line BC. This implies that the distance between line AD and BC are the same at every point. Therefore, line AD and line BC are parallel.

The length of a rectangle is represented by 3x + 4, and its width is represented by
2x + 6. The perimeter of the rectangle is 45 units. Find the value of x.
Answer:
5
Step-by-step explanation:
Length of rectangle = 3x + 4
Width of the rectangle = 2x + 6
Perimeter of rectangle = 2(l + b)
45 = 2(3x + 4 + 2x + 6)
45 = 2(5x + 10)
45 = 10x + 20
45 - 20 = 5x
25 = 5x
x = 25/5
x = 5

Answer:
<1 = 100
<2 = 80
Step-by-step explanation:
Angle 1 and angle 2 are supplementary
Supplementary angles add to 180 degrees
<1 + <2 = 180
The angles are in a ratio of 5 to 4
Multiply by x to get the measure of each angle
<1 = 5x <2 = 4x
5x+4x = 180
Combine like terms
9x = 180
Divide by 9
9x/9 =180/9
x =20
<1 = 5x = 5*20 = 100
<2 = 4x = 4*20 = 80
Answer:
m1 = 122
m2 = 58
m5 = 68
Step-by-step explanation:
m2 = 180 - 54 - 68 = 58
m1 = 180 - m2 = 180 - 58 = 122
m5 = 180 - 58 - 54 = 68

Compute the difference quotient, f(x+h)-f(x)/h , for the function f(x) = 3/2x. Show all algebraic work and steps, then circle/box your final answer.
Answer:
[tex]\frac{f(x + h) - f(x)}{h} = \frac{3}{2}[/tex]
Step-by-step explanation:
Given
[tex]f(x) = \frac{3}{2}x[/tex]
Required
Calculate [tex]\frac{f(x + h) - f(x)}{h}[/tex]
First, we calculate f(x + h)
[tex]f(x) = \frac{3}{2}x[/tex]
[tex]f(x + h) = \frac{3}{2}(x + h)[/tex]
[tex]f(x + h) = \frac{3}{2}x + \frac{3}{2}h\\[/tex]
The equation becomes:
[tex]\frac{f(x + h) - f(x)}{h}[/tex]
[tex]\frac{f(x + h) - f(x)}{h} = \frac{\frac{3}{2}x + \frac{3}{2}h - \frac{3}{2}x}{h}[/tex]
[tex]\frac{f(x + h) - f(x)}{h} = \frac{\frac{3}{2}x - \frac{3}{2}x+ \frac{3}{2}h}{h}[/tex]
[tex]\frac{f(x + h) - f(x)}{h} = \frac{\frac{3}{2}h}{h}[/tex]
[tex]\frac{f(x + h) - f(x)}{h} = \frac{3}{2}[/tex]

A population has a standard deviation of 7.89. What is the approximate standard error of the mean for a sample size of 300?
A. 17.32
B. 0.026
C. 2.20
D. 0.46
The approximate standard error of the mean for a sample size of 300 will be option D. 0.46.
What is the standard deviation?Standard deviation is defined as the amount of variation or the deviation of the numbers from each other.
Here the approximate standard error will be calculated by dividing the standard deviation from the square root of the sample size
Approximate standard error = 7.89/√300=0.455555=0.46
Hence the approximate standard error of the mean for a sample size of 300 will be option D. 0.46.

Jake sold 42 tickets while Jeanne sold 9 tickets. The questions is asking for the ratio in simplest form the number of tickets Jeanne sold to the number Jake sold. Since we know the amount they sold, let's put it into a ratio factor by Jeannes to Jakes.
9 : 42

When you are doing derivatives, you don't want to do it right away because there is still ( ) we need to remove that first get,
g(x)=3x^4-6x
Now we can do the derivatives!
g(x)=12*x^3 - 6
