Answer: D. -37pi/9

Step-by-step explanation:

The rest of the answer choices have a reference angle of 2pi/9

The reference angle of π/9 is -37π/9 option (d) -37π/9 is correct.

It is defined as the angle formed between the terminal side and x-axis, known as the reference angle.

We have an angle of π/9

The angle -37π/9 is a reference angle of π/9 because:

=  (2π+2π)-37π/9  (one complete revolution is 2π)

= (18 + 18-37)π/9

= π/9

Thus, the reference angle of π/9 is -37π/9 option (d) -37π/9 is correct.

Answer:

B

Step-by-step explanation:

Use Desmos graphing calculator

Answer:

x = -2y^2

Explanation Part 1:

It's not vertical, and thus it's not a standard (y = ax^2 + b) parabola.

This must mean it's either x = 2y^2 or x = -2y^2

Explanation Part 2:

You can test values into either one to check if it works

Take (-2, 1) for example, doesn't have to be a precise coordinate pair:

First Equation

x = 2y^2

-2 = 2(1)^2

-2 = 2(1)

-2 = 2

DOESN'T WORK!

Second Equation

x = -2y^2

-2 = -2(-1)^2

-2 = -2(1)

-2 = -2

IT WORKS!

Answer:

12.1

Step-by-step explanation:

A^2+b^2=c^2

a^2+49=196

196-49=a^2

sqrt147=a

12.1=a

Answer:

x = 12.1 in.

Step-by-step explanation:

a² + b² = c²

7² + x² = 14²

49 + x² = 196

x² = 147

x = sqrt(147)

x = 12.1 in.

Answer:

Step-by-step explanation:

Try dividing the first equation by 3.  The result will be identical to the second equation.  Thus, we have two lines that coincide, and therefore there are an infinite number of solutions.

Answer:

-176

Step-by-step explanation:

Let x = -8

f(-8) = 11 (-8-24) / 2

         Simplify the parentheses

f(-8) = 11 ( -32)/2

        = 11 (-16)

        = 176

0.65 represent the percent of battery life remaining decreases by 65% each hour. Option D is correct.

A mathematical statement consisting of an equal symbol between two algebraic expressions with the same value is known as an equation.

The fact that the exponential growth function's equation is provided by;

y=a(1+r)ˣ

Given expression;

y = 100(0.65)ˣ

Y represents the percent of battery life

The number of hours x

The battery life percentage declines by 65 percent per hour, or 0.65.

Hence option D is correct.

Answer:

The value of the tangent is [tex]-\frac{4}{5}[/tex].

Step-by-step explanation:

Let be [tex]A(x,y) = (-10, 8)[/tex] on the terminal side of an angle in standard position and let be [tex]O(x,y)[/tex] the origin of the angle and the origin of the Cartesian plane. By definition of tangent, we make use of the following expression:

[tex]\tan \theta = \frac{y_{A}-y_{O}}{x_{A}-x_{O}}[/tex] (1)

Where:

[tex]x_{A}, x_{O}[/tex] - x-Coordinates of point A and point O.

[tex]y_{A}, y_{O}[/tex] - y-Coordinates of point A and point O.

If we know that [tex]x_{A} = -10, x_{O} = 0[/tex], [tex]y_{A} = 8[/tex] and [tex]y_{O} = 0[/tex], then the value of the tangent is:

[tex]\tan \theta = \frac{y_{A}-y_{O}}{x_{A}-x_{O}}[/tex]

[tex]\tan \theta = \frac{8-0}{-10-0}[/tex]

[tex]\tan \theta = -\frac{4}{5}[/tex]

Step-by-step explanation:

Answer:

5 years

Step-by-step explanation:

Given that

The current population is 45,000

The rate of interest in declining would be 4.5% per year

The expected population is 35,746

We need to find out the no of years

Since the rate of interest decrease by 4.5% per year so after decreasing it the percentage would be 0.955

Now

Year 1 = 45,000 × 0.955 = 42,975

Year 2 = 42,975 × 0.955 =  41,041.125

Year 3 = 41,041.125 × 0.955 = 39,194.27

Year 4 = 39,194.27 × 0.955 = 37,430.53

Year 5 = 37,430.53 × 0.955 = 35,746.16

Hence, the no of years would be 5

Answer:

25

Step-by-step explanation:

We already have our first value 36 and the second value 144. Let's assume the unknown value is Y which answer we will find out.

As we have all the required values we need, Now we can put them in a simple mathematical formula as below:

STEP 1 Y =  36/ 144

By multiplying both numerator and denominator by 100 we will get:

STEP 2 Y =  36/ 144  ×  100/ 100 =  25/ 100

STEP 3 Y = 25

Finally, we have found the value of Y which is 25 and that is our answer.

If you want to use a calculator to find 36 is what percent of 144, simply enter 36 ÷ 144 × 100 and you will get your answer which is 25
