Answer:

Coordinate plain

Step-by-step explanation:

airplane... i think you know what that is, and quadrant is the squares sectored off by a coordinate plane.

Answer:

No real zeros for the function.

Explanation:

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.

But complex zeros are:

         [tex](x-20)^{2} +5=0[/tex]

          [tex](x-20)^{2} =-5[/tex]

A graph is a way to represent a lot of data in a visual format. The shape of this graph is best described as skewed.

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.

Answer:

Answer:

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

Step-by-step explanation:

According to the given information,

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

Similarly,

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

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

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

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

The given table is an example of constant exponential decay.

It is given that

X          Y

-4          16

-1           2

2          0.25

4          0.0625

5          0.03125

An exponential function is a relation of the form y = a^x, with the independent variable x ranging over the entire real number line as the exponent of a positive number a.

The y-value at -4 is 16 while the y-value at -1 is 2, a decrement of 1/8 times for an increment in x-value by 3

Again, the y-value at 2 is 0.25 while the y-value at 5 is 0.03125, a decrement of 1/8 times for an increment in x-value by 3.

In both cases, the rate of decrement is constant.

So we can say that this is an example of constant exponential decay.

We can also see this behavior from the attached graph.

Therefore, the given table is an example of constant exponential decay.

Given that Alyssa thinks that her school is more fashion-conscious and that students spent more than $195.00.

She collected data from 20 people in her high school and found that the average price spent on a prom dress was $208.00.

Since she wants to check whether the sample mean [tex]\mu[/tex] is the same as the population mean  [tex]\mu[/tex] = 195

[tex]H_{0} =\mu=195\\H_{a} =\mu > 195[/tex]

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

The solutions of the given equations are given by equating the

variables to gives;

First part;

The given functions are;

y = -3·x² + 24·x + 3, and y = -4·x² + 25·x + 15

When the balloons collided, we have;

The height are equal, which gives;

y = y

-3·x² + 24·x + 3 = -4·x² + 25·x + 15

-3·x² + 24·x + 3 - (-4·x² + 25·x + 15) = x² - x - 12 = 0

Which gives;

x² - x - 12 = (x - 4) × (x + 3) = 0

x = 4, and x = -3

The time at which the balloon collide at the highest point is therefore;

Second part;

The given system of equations are;

x - y = 6

y = x² - 6

y = x - 6

Which gives;

x - 6 = x² - 6

x = x²

Which gives;

x = 0 or x = 1

Similarly, we have;

x = y + 6

Which gives;

y = (y + 6)² - 6

y² + 11·y + 30 = 0

(y + 5)·(y + 6) = 0

Which gives;

y = -5, or y = -6

When y = -5, we have; x = -5 + 6 = 1

The solution are therefore;

Third part;

The equations are; y = x + 7 and y = x² - 3·x + 7

At the solution, the u-values are equal, which gives;

y = y

x + 7 = x² - 3·x + 7

x² - 3·x + 7 - (x + 7) = 0

x² - 4·x = 0

x·(x - 4) = 0

x = 4, or x = 0

When x = 4, y = 4 + 7 = 11

When x = 0, y = 0 + 7 = 7

The solutions are located at points;

Fourth part;

Given that the point of intersection of the line and the quadratic function

is the point (2, 0), we have;

On the linear function, when y = 0, x = 2

The possible linear function functions is therefore;

x + y = 2

From the quadratic function that accompanies the above linear function, we have;

y = x² + 3·x + 2

When x = 0, y = 0² + 3×0 + 2 = 2

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 )
