What is the perimeter of a pentagon with side length 35cm?

Using an exponential function, it is found that the expression that can be used to calculate the total percent increase in their annual salary from the first year to the last year is given by:

[tex]P = 100\% \times [(1 .03)^t - 1][/tex]

An increasing exponential function is modeled by:

[tex]A(t) = A(0)(1 + r)^t[/tex]

In which:

As a percentage, the increase is modeled by:

[tex]P = 100\% \times [(1 + r)^t - 1][/tex]

In this problem, the growth rate is of r = 0.03, hence:

[tex]P = 100\% \times [(1 + 0.03)^t - 1][/tex]

[tex]P = 100\% \times [(1 .03)^t - 1][/tex]

slope = 4

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

The constant of proportionality is 6

Step-by-step explanation:

Recall the equation for direct variation is [tex]y=kx[/tex] where [tex]y[/tex] varies directly with [tex]x[/tex] and [tex]k[/tex] is the constant of proportionality. If we take any listed coordinate point, we can determine the value of [tex]k[/tex]. I will use (20,120) as an example:

[tex]y=kx\\\\120=k(20)\\\\6=k[/tex]

Therefore, the constant of proportionality is 6

Answer:

Approximately 8.234 inches.

Step-by-step explanation:

The area for a sphere is 4πr²

=> r² = 213 : 4 : π = approx. 16.95
=> r = sqrt (16.95) = approx. 4.117

=> d = 4.117 x 2 = approx. 8.234 inches

The time that Rudy finished the race was 11:10: 10 am.

The time that Teresa's group finished the race was 10:50:08 am.

The formula that can be used to determine the time is Time = distance / average speed

Teresa's group = 26.6 / 16 = 1.6625 = 1 hour 40 minutes 10 seconds = 11:10: 10 am

Rudy's group = 16.6 / 12.5 = 1.328 = 1 hour 20 minutes 8 seconds = 10:50:08 am

The null hypothesis and the research hypothesis respectively refers to;

A: Population; Sample

Null hypothesis is defined as a working hypothesis making a claim about the population parameter in question. This means it deals with an overall Population.

Whereas, the alternative hypothesis also called the research hypothesis is one that seeks to disapprove or validate the null hypothesis and as such it is based on the results taken from a sample of a given population from which the null hypothesis is based.

Answer:

x=14

Step-by-step explanation:

This shape is a pentagon, as it has 5 sides. The formula to find the sum of the interior angles of a polygon is:

(n-2)*180

In this case n represents the number of sides. We can plug 5 into the equation to get...

(5-2)*180=3*180=540

Since all sides are equal, all angles are equal too therefore one angle is equivalent to...

540/5=108

This means...

9x-18=108

Add 18 to both sides

9x-18+18=108+18

9x=126

Divide both sides by 9

x=14

Answer:

x = 14

Step-by-step explanation:

This is a pentagon and there are five sides in a pentagon. All of the sides degrees added together makes 540.

Since the angles are the same and the average angle of every pentagon is 108, then 9x - 18 = 108.

108 + 18 = 126

9x = 126

9x/9 = 126/9

x = 14

Answer:

  90.7

Step-by-step explanation:

The relevant trig relation is ...

  Sin = Opposite/Hypotenuse

  sin(S) = RT/ST

  ST = RT/sin(S) = 63/sin(44°) ≈ 90.7

The length of ST is about 90.7 units.

Answer:

80

Step-by-step explanation:

I took the test

The measure of the fifth angle will be 80°. Then the correct option is B.

The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.

Let 'n' be the number of sides of the polygon. Then the sum of the interior angles of the polygon is given as,

Sum of angles = (n - 2) × 180°

The sum of the interior angle of the pentagon is given as,

Sum of angles = (5 - 2) × 180°

Sum of angles = 3 × 180°

Sum of angles = 540°

And the diagram is given below. The equation is given as,

x + 90° + 90° + 140° + 140° = 540°

x + 460° = 540°

x = 540° - 460°

x = 80°

The measure of the fifth angle will be 80°. Then the correct option is B.
