Answer:

Step-by-step explanation:

Alright. Looking at the graph, angle CGE is equal to angle FGD.

FGD = 90-73

FGD = 17

Therefore, as angle CGE is equal to angle FGD, angle CGE is equal to 17.

Answer: 17 degrees.

By applying angle relationships and recognizing the equality of angles, we determined that angle CGE measures 17 degrees, as it is equal to angle FGD in the context of the graph.

In geometry, analyzing angles within shapes and figures is fundamental. Here, we have a graph depicting intersecting lines and angles. Let's break down the steps and reasoning for finding the measurement of angle CGE:

1. Angle CGE and Angle FGD:

First, we observe the graph and notice that angle CGE is mentioned to be equal to angle FGD. This equivalence allows us to focus on finding the measurement of angle FGD, which, in turn, will be the measurement of angle CGE.

2. Calculation of Angle FGD:

We know that angle FGD is related to a right angle, as indicated by the angle symbol "90" next to it. To calculate the measurement of angle FGD, we use the fact that the sum of angles around a point is 360 degrees, and the angle opposite to a right angle is complementary, totaling 90 degrees.

So, we calculate angle FGD as follows:

Angle FGD = 90 degrees (right angle) - 73 degrees (given angle)

Angle FGD = 17 degrees

3. Angle CGE:

Since angle CGE is stated to be equal to angle FGD, we determine that angle CGE is also 17 degrees.

Answer:

Option A.

Step-by-step explanation:

Priscilla graphed function g(x), a transformation of the quadratic parent function f (x) = [tex]\frac{1}{2}[/tex] f ( x+2 ) - 1

(1) She graphed the vertical compression correctly

(2) Priscilla graphed the vertical shift of (-1) means 1 unit downwards on y-axis correctly.

Substitute g(x) for x in f(x) and evaluate:

  f(g(x)) = f(x^(1/3) -1)

  = ((x^(1/3) -1) +1)^3 -5

  = (x^(1/3))^3 -5

  = x^(3/3) -5

  f(g(x)) = x -5

If the functions were inverses, the value of f(g(x)) would be x. It is not, so the functions are not inverses.

Answer:

c. 68, 112

Step-by-step explanation:

The angle is our unknown, so we will call it x.  If the angle is x, then its supplement is 180 - x (supplementary angles add up to equal 180).  The word "is" means "equals", so putting the equation together looks like this:

180 - x = 2x - 24.  Add x to both sides and at the same time add 24 to both sides (combining like terms, in other words):

204 = 3x so

x = 68

x is the angle measure, so the angle is 68 and its supplement is 180 - 68 = 112

The angle will be 68 and its supplement will be 112.

It is given that supplement of an angle is 24 less than twice the measure of the angle.

We have to find out the measure of the angle and its supplement.

What are the supplementary angles ?

The supplementary angles are the angles whose sum is equal to 180° i.e., sum of angles 150° and 30° equal to 180°.

The angle is unknown. Let's assume angle be x.  

We know that , supplementary angles add up to equal 180.

If the angle is x, then its supplement will be :

180 - x ----------- Equation 1

Also ;

angle's supplement is equal to ;

2 × x - 24 ----------- Equation 2

Keeping both the equations equal ;

180 - x = 2x - 24.  

180 + 24 = 3x

204 = 3x

x = 68

Supplement will be ;  180-x = 180 - 68 = 112

Thus , x is the angle measure, so the angle is 68 and its supplement is 112.

Answer:  (f·g)(x) = -5x³ - 31x² + 62x + 18

               (f·g)(-1) = -70

(fog)(x) = 25x² - 130x + 155

(fog)(-1) = 310

Step-by-step explanation:

f(x) = x² + 8x + 2          g(x) = -5x + 9

(f·g)(x) = (x² + 8x + 2)(-5x + 9)

          = -5x³ + 9x²

                    - 40x² + 72x

                               - 10x + 18

          = -5x³ - 31x² + 62x + 18

(f·g)(-1)= -5(-1)³ - 31(-1)² + 62(-1) + 18

         =  -5(-1)  - 31(1)    - 62      + 18

         =    5     -   31      - 62      + 18

                                +   2

           = 25x² - 130x + 155

(fog)(-1) = 25(-1)² - 130(-1) + 155

            = 310

It wasn't clear if you wanted multiplication or composition so I solved both.

The composition (f⋅g)(x) is 50, and the product of functions (f.g)(-1) is -20.

To find the composition of the functions f(x) and g(x), denoted as (f⋅g)(x), we first need to determine g(x). Given g(x) = -5 + 9, we simply add these numbers together to get g(x) = 4. With g(x) found, we can now substitute g(x) into f(x) to find the composition. To do this, wherever there is an x in f(x), we replace it with 4.

So, (f⋅g)(x) = f(g(x)) = f(4) = 4^2 + 8(4) + 2 = 16 + 32 + 2 = 50.

Next, to find (f.g)(-1), which represents the product of the two functions evaluated at x = -1, we evaluate both f(-1) and g(-1). We already know that g(x) is constant at 4, so g(-1) = 4. Now we find f(-1):

f(-1) = (-1)^2 + 8(-1) + 2 = 1 - 8 + 2 = -5.

Thus, the product at x = -1 is:

(f.g)(-1) = f(-1) ⋅ g(-1) = (-5) ⋅ 4 = -20.

Answer:

$42,890

Step-by-step explanation:

The standard form for an exponential equation is

[tex]y=a(b)^x[/tex]

where a is the initial amount value and b is the growth rate or decay rate and t is the time in years.  Since we are dealing with money amounts AND this is a decay problem, we can rewrite accordingly:

[tex]A(t)=a(1-r)^t[/tex]

where A(t) is the amount after the depreciation occurs, r is the interest rate in decimal form, and t is the time in years.  We know the initial amount (70,000) and the interest rate (.04), but we need to figure out what t is.  If the car was bought in 2006 and we want its value in 2018, a total o 12 years has gone by.  Therefore, our equation becomes:

[tex]A(t)=70,000(1-.04)^{12}[/tex] or, after some simplification:

[tex]A(t)=70,000(.96)^{12}[/tex]

First rais .96 to the 12th power to get

A(t) = 70,000(.6127097573)

and then multiply.

Answer:

4280 passes were sold

Step-by-step explanation:

The unknown we are looking for the number of passes that were sold.  We don't know how MANY were sold, but we do know that the cost of ONE is 12.50.  We represent the number of passes at that price per pass as

12.50x

We also know that money earned from the sale of this unknown number of passes came to 53,500.  Our equation then becomes

12.50x = 53,500

Solving for x, we divide both sides by 12.50 to get that

x = 4280

Final answer:

To find the number of annual visitor passes sold at Woodland Mound Park, divide the total sales ($53,500) by the price per pass ($12.50), resulting in 4,280 passes sold.

Explanation:

The question asks how many annual visitor passes were sold at Woodland Mound Park last year if each pass costs $12.50 and the total amount raised from pass sales was $53,500. To find the number of passes sold, you'll need to divide the total sales by the price per pass. Here is the step-by-step calculation:

[tex]y=10(2)^x[/tex]

Step-by-step explanation:

This is an exponential function.  Peter is not simply adding $10 a week to his savings, he's doubling each value each week.  The first case of adding $10 a week is linear.  

The standard form of an exponential equation is

[tex]y=a(b)^x[/tex]

where a is the initial amount and b is the growth or decay factor.  We know a = 10 because we are told he started with $10.  After the first week he would have $20 then because $10 doubled is $20.  That coordinate is (1, 20).  We will use that in place of x and y and solve for b:

[tex]20=10(b)^1[/tex]

b to the first is just b, so what we have essentially is 10b = 20, so b = 2.  The equation then is:

[tex]y=10(2)^x[/tex]

Step-by-step explanation:

Quadrant 2 means cosine is negative.

So [tex] \sin(\theta)=\frac{2}{3} =\frac{\text{ opp }}{\text{ hyp }} [/tex]

So the adjacent side is [tex] \sqrt{3^2-2^2}=\sqrt{9-4}=\sqrt{5} [/tex]

So [tex] \cos(\theta)=-\frac{\sqrt{5}}{3} [/tex]

Now to find [tex] \tan(2 \theta) [/tex]

[tex] \tan(2 \theta) =\frac{2\tan(\theta)}{1-\tan^2(\theta)}[/tex]

We will need [tex] \tan(\theta) [/tex] before proceeding.

[tex] \tan(\theta) =\frac{\sin(\theta)}{\cos(\theta)}=\frac{\frac{2}{3}}{\frac{-\sqrt{5}}{3}}=\frac{-2}{\sqrt{5} } [/tex]

Now plug it in and the rest is algebra.

[tex] \tan(2 \theta) =\frac{2\tan(\theta)}{1-\tan^2(\theta)} =\frac{2 (\frac{-2}{\sqrt{5}}}{1-\frac{4}{5}} [/tex]

Now the algebra, the simplifying.... We need to get rid of the compound fraction.  We will multiply top and bottom by [tex] 5 \sqrt{5} [/tex]

This will give us

[tex] \frac{-20}{\sqrt{5}} [/tex]

Multiply top and bottom by [tex] \sqrt{5} [/tex]

Final answer:

To find tan2θ when sinθ = 2/3 and θ is in Quadrant II, we use the Pythagorean identity to find cosθ and the double angle identity for tangent. After calculation, tan2θ = -4√5.

Explanation:

If sinθ = 2/3 and θ is located in Quadrant II, we first have to find cosθ and then use the double angle identity for tangent to find tan2θ. Since sinθ is positive in Quadrant II and cosθ must be negative (as the x-values are negative in Quadrant II), we can use the Pythagorean identity sin2θ + cos2θ = 1 to find cosθ. Thus, cosθ = -√(1 - sin2θ) = -√(1 - (2/3)2) = -√(1 - 4/9) = -√(5/9) = -√5/3.

The double angle identity for tangent is tan2θ = 2tanθ / (1 - tan2θ). But first, we find tanθ = sinθ/cosθ = (2/3) / (-√5/3) = -2/√5. Then, tan2θ = 2(-2/√5) / (1 - (-2/√5)2) = -4/√5 / (1 - 4/5) = -4/√5 / (1/5) = -20/√5. Simplifying further, we multiply by √5/√5 to rationalize the denominator, which gives us tan2θ = -20√5/5 = -4√5.

A reflection is a transformation where the mirror image of a figure is shown directly opposite its line of reflection.
