find x

Answers

Answer:

Step-by-step explanation:

the measure of a secant- tangent angle is half the difference of the intercepted arcs, then

[tex]\frac{1}{2}[/tex] (154 - (12x + 2) ) = 6x + 4 ( multiply both sides by 2 to clear the fraction )

154 - 12x - 2 = 12x + 8 , that is

152 - 12x = 12x + 8 ( subtract 12x from both sides )

152 - 24x = 8 ( subtract 152 from both sides )

- 24x = - 144 ( divide both sides by - 24 )

x = 6

What is a graph?

A graph is a way to represent a lot of data in such a visual format that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.

here, we have,

A.) A symmetric graph is a graph in which the left half of the graph looks like the mirror image of the right half of the graph. Since the graph has no symmetry it is not a symmetric graph.

B.) Skewness is a distortion or asymmetry in a set of data that deviates from the symmetrical bell curve, or normal distribution. The curve is said to be skewed if it is displaced to the left or right. As we can see that the shape of the graph is the left tilted bell shape.

C.) A constant graph is a graph in which the value of each bar lies on the same horizontal value. Since the shape of the graph is not a horizontal line, it is not a constant shape graph.

D.) When a graph has Peak and Valleys in a graph, the values of the graph are different from each other, therefore, forming peaks and valleys in a graph, which looks like a spline. Since the value of the graph is decreasing towards the right side of the graph. Therefore, the graph of the shape is not of a peak and valley.

Thus, the shape of this graph is best described as skewed.

Mr. Ingle purchased a Prius for $42,500. If the car depreciates at a rate of 10%, what is
the value of the car after 7 years?

Answers

Based on the cost of Mr. Ingle's car and the depreciation rate, the value after 7 years will be $20,327.62.

What would be the value after 7 years?

This can be found by the formula:

= Cost of car x ( 1 - depreciation rate) ^ number of years given

Solving gives:

= 42,500 x (1 - 10%)⁷

= 42,500 x 0.4782969

= $20,327.62

8. Jenny is getting dressed for school,
• She has 2 pairs of black pants, 1 pair of brown pants, and 2 pairs of blue pants in her
closet
. She also has 2 pink T-shirts and blue T-shirts in her closet.
• Without looking, Jonny pulls out one pair of pants and one T-shirt from her closet.
What is the probability that Jenny pulls out a pair of black pants and a blue T-shirt?

Answers

Answer:

[tex]\huge\boxed{\bf\: Probability = \frac{4}{9}}[/tex]

Step-by-step explanation:

According to the given information,

Pairs of black pants = 2Pair of brown pants = 1Pairs of blue pants = 2

Then, total pairs of pants = 2 + 1 + 2 = 5

Similarly,

Pink T-shirts = 2Blue T-shirts = 2

Then, total number of T-shirts = 4

This gives us the total nunber of clothing articles with Jenny, i.e.,

Total pairs of pants + Total number of T-shirts

= 5 + 4

= 9

Now, the probability of pulling out a pair of black pants & a blue T-shirt will be:

Total pairs of black pants + Total nunber of blue T-shirts/Total clothing articles

= 2 + 2 / 9

= 4/9

What are all the real zeros of y=(x-20)^2 +5

Please show step by step I'm so lost!!

Answers

Answer:

No real zeros for the function.

Explanation:

zero of a function f, if f(r) = 0

solve:

[tex]\sf y=(x-20)^2 +5[/tex]

so when f(y) = 0

[tex]\hookrightarrow \sf (x-20)^2 +5 = 0[/tex]

[tex]\hookrightarrow \sf (x-20)^2 = -5[/tex]

[tex]\hookrightarrow \sf (x-20) = \sqrt{-5}[/tex]

[tex]\hookrightarrow \sf x = \pm \sqrt{-5} +20[/tex]

[tex]\hookrightarrow \sf x = \sqrt{-5} +20, \ \sf x = -\sqrt{-5} +20[/tex]

check:

[tex]\hookrightarrow f \sf (\sqrt{-5} +20) = Not \ applicable[/tex], [tex]f \sf (-\sqrt{-5} +20) = Not \ applicable[/tex]

Answer:

No real zeros.

Step-by-step explanation:

Given... y = [tex](x-20)^{2} +5[/tex]

Since above equation has no real real value, there are no zeros.

A proportion is a fraction of a total amount.

For the four samples, the proportions are: {0.3, 0.15, 0.26, 0.29}.

Hence, the mean proportion is given by:

M = (0.3 + 0.15 + 0.26 + 0.29)/4 = 0.25

Juan is clearing land in the shape of a circle to plant a new tree. The diameter of the space he needs to clear is 52 inches. By midday, he has cleared a sector of the land cut off by a central angle of 140 . What is the arc length and the area of land he has cleared by midday?

Answers

The central angle of 140 degrees illustrates the degree measure of the arc

The arc length cleared is 63.54 inches and the area of the land cleared is 826.00 square inches

How to determine the arc length

The given parameters are:

Central angle = 140 degrees

Diameter = 52 inches

The length of the arc is then calculated s:

[tex]L = \frac{\theta}{360} * \pi d[/tex]

Substitute known values in the equation

[tex]L = \frac{140}{360} * 3.142 * 52[/tex]

Evaluate the products

[tex]L = \frac{22873.76}{360}[/tex]

Evaluate the quotient

[tex]L = 63.54[/tex]

Hence, the arc length cleared is 63.54 inches

How to determine the area of the land cleared

The area is calculated s:

[tex]A = \frac{\theta}{360} * \pi (d/2)^2[/tex]

Substitute known values in the equation

[tex]A = \frac{140}{360} * 3.142 * (52/2)^2[/tex]

Evaluate the products

[tex]A = \frac{297358.88}{360}[/tex]

Evaluate the quotient

[tex]A = 826.00[/tex]

Hence, the area of the land cleared is 826.00 square inches

Answer:

Step-by-step explanation:

The yards of silk bought is 1.49 yards and the yard of cotton bought is 2.76 yards.

The two equations are known as simultaneous equation. They would be solved using elimination method.

x + y = 4.25 equation 1

16.90x + 4y = 36.25 equation 2

where:

x = yards of silk bought

y = yards of cotton bought

In order to determine the value of x, multiply equation 1 by 4.

4x + 4y = 17 equation 3

Subtract equation 3 from 2

19.25 = 12.90x

Divide both sides of the equation by 12.90

x = 1.49 yards

In order to determine the value of y, substitute for x in equation 1

1.49 + y = 4.25

y = 4.25 - 1.49

y = 2.76 yards
