The trend line passes through (10, 9) and (35, 0) will be 9x + 25y = 315.

Suppose the given points are (x₁, y₁) and (x₂, y₂), then the equation of the straight line joining both two points is given by

[tex]\rm (y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)[/tex]

The scatter plot with the trend line below shows the data comparing wind speed and wind chill. Wind Chill (˚F) Wind Speed (mph). The trend line passes through (10, 9) and (35, 0).

Write an equation for the trend line.

(x₁, y₁) → (10, 9)

(x₂, y₂) → (35, 0)

Then we have

        y - 9 = -9/25(x - 10)

25y - 225 = -9x + 90

 9x + 25y = 315

f(x) is faster

Step-by-step explanation:

In case it is x^2 then f(x) will be faster.

If you draw these two function in the graph. You can see that

Or you can add any value randomly and see that

Ex:

when x = 5

f(x) = 25, g(x) = 10

when x = 20

f(x) = 400, g(x) = 40

when x is 4 times larger. g(x) is 4 times larger while f(x) is 16 times larger

Answer:

1479 people

Step-by-step explanation:

If the amount employed is 8381, that means 8381 is 85% of the population. 8381/85 = 98.6

Every 1% of the population is 98.6, so we can just do 15 x 98.6 to get 1479

Answer:

9,860

Step-by-step explanation:

100% - 15% = 85 % = 85/100

85/100 * 8381/x

85x = 838,100

838,100/85 = 9,860

Step-by-step explanation:

the general vertex form is

y = a(x - h)² + k

with (h, k) being the vertex of the curve.

after doing all the multiplications we get

y = a(x² - 2hx + h²) + k = ax² - 2ahx + ah² + k

now we have

y = x² + 24x + 124

and we can compare

ax² = x²

a = 1

-2ahx = -2hx = 24x

-2h = 24

h = 24/-2 = -12

ah² + k = 124

(-12)² + k = 124

144 + k = 124

k = -20

so, the vertex form is

y = (x + 12)² - 20

Answer:

x ≈ 10.7

Step-by-step explanation:

Is given in the picture that x is the radius of the circle.

The radius of a circle and the tangent line to the circle form a right angle, therefore our triangle is a right triangle.

We can  apply the Pythagorean Theorem to find one equation that will have one unknown x.

         (x+12)² = x² +20² , use that (a+b)² = a²+b²+2ab

x²+12²+2·x·12 = x² +20², subtract x² from both sides of the equation

     12² + 24x  = 20², subtract 12² from both sides of the equation

              24x = 20²-12², raise to power and combine like terms

              24x = 256, divide by 24  both sides of the equation

                  x = 10.6666666..., round to the nearest tenth

                 x ≈ 10.7

I assume you mean the equation

[tex]i^{2x+3} = i[/tex]

Since i = √(-1), we have i⁴ = 1 and so i⁵ = i. Then 2x + 3 must be some multiple of 5.

Now just check for which of the given choices that this holds:

x = 16   ⇒   2x + 3 = 35   (yes)

x = 11   ⇒   2x + 3 = 25   (yes)

x = 10   ⇒   2x + 3 = 23   (no)

x = 14   ⇒   2x + 3 = 31   (no)

Answer: [tex]x < 4[/tex]

Step-by-step explanation:

Our inequality is [tex]3x-3 < 9[/tex]

We will add 3 to both sides. (addition property of equality)

Simplify [tex]9 + 3 9+3 9+3 ~to ~12[/tex].

Then divide both sides by 3. (division property of equality)

[tex]3x[/tex]÷[tex]3 < 12[/tex]÷[tex]3[/tex]

Answer:

c) Five out of 8 equal parts of a whole

Step-by-step explanation:

The statement "Five out of 8 equal parts of a whole" means the fraction of 5/8. Hence, option (c) is the correct answer.

Answer:

"Five out of eight equal parts of a whole"

Step-by-step explanation:

In a fraction, the numerator (top part) is saying "this number out of the number below it."

The denominator (lower part) is the number below it that we are taking the proportion out of.

A denominator is ALWAYS equal parts, so if we match up the phrase: "5 out of eight equal parts of a whole"

The graph of a function is shown in the picture and the amplitude will be 6

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have a trigonometric function:

[tex]\rm y = -6\cos\left(5x\right)-3[/tex]

As we know, the range for the cosx is [-1, 1]

The maximum value of function y = -6cos(5x)—3 is 3 and minimum value is -9.

The amplitude = 6

Thus, the graph of a function is shown in the picture and the amplitude will be 6

Answer:

15 feet

Step-by-step explanation:

From the question above,we are asked to find the volume of a cabinet with the following dimensions:

Height is five feet

Width is eighteen inches

And a depth of two feet.

Here it is quite obvious that we ate dealing with a cuboidal object since its dimensions differ from one another.

So volume of a cuboid as we all know is :

Length multiplied by width and then height

We should head straight away to the calculations, but we need to remember that the width is in inches and needs to be converted to feet

1 inch = 1/12 feet

18 inches = 18× 1/12

= 1.5 feet

L×W×H

= 1.5×5×2

= 15 feet

Based on the above information, it can be inferred that Sarah saves $6,900 per year.

Taking into account that her new employer is going to give her a free health service and that before she paid $575 for the health service monthly, to calculate her savings per year we must multiply the value of the health service by the number of months of one year (12).

Based on the above, it can be inferred that Sarah is saving $6,900 per year on health care.
