Answer:

[tex]33[/tex]

Step-by-step explanation:

Define functions:

[tex]r(x) = 2x+1\\s(x) = -x^2[/tex]

Substitute [tex]s(x)[/tex] into [tex]r(x)[/tex]:

[tex]2(-x^2) + 1[/tex]

Solve for value:

[tex]= 2((-4)^2)+1\\= 2(16) + 1\\= 32 + 1\\= 33[/tex]

** assuming that the function of [tex]s(x)[/tex] the x value is squared with the negative sign.

The slope of the function y = 2 + 34x is 34 and the y-intercept of the function y = 2 + 34x is 2.

First, let us understand the slope intercept form;

The slope intercept form is simply a way of writing a line's equation so that the slope (steepness) and y-intercept (where the line crosses the vertical y-axis) are obvious.

We know that the slope intercept form of a line is y = mx + c where m is the slope of the line and b is the y-intercept of the line.

We are given:

y = 2 + 34x

y = 34x + 2

Compare with y = mx + c, we will get;

m = 34

b = 2

So, the slope is 34 and the y-intercept is 2.

Thus, the slope of the function y = 2 + 34x is 34 and the y-intercept of the function y = 2 + 34x is 2.

We have,

Money Spent (x)      $0  $20  $40  $60

We can have the following points from the table.

(0, 4), (20, 12), (40, 20), and (60, 28).

Now,

Choose two points:

(0, 4) and (20, 12)

m = (12 - 4) / (20 - 0)

m = 8 / 20

m = 2/5

Now,

(0, 4) = (x, y)

y = mx + c

4 = c

c = 4

Step-by-step explanation:

Given points on the scatter plot:

Plot the given points and draw a line of best fit (see attachment).

As the y-values decrease as the x-values increase, the slope of the line of best fit is negative.

From inspection of the plotted line of best fit, we can see that the y-intercept is approximately 5.7.

Therefore, the equation that is appropriate for the line of best fit is:

Answer:

P = $11233.08

Step-by-step explanation:

Another word for deposit is the principal and the compounded monthly indicates we're working with compound interest.

The formula for compound interest is:

[tex]A(t)=P(1+\frac{r}{n} )^{rt}[/tex], where P is the principal ("deposit"), r is the rate, n is the number of compounding periods, and t is the time.

Before solving, we will need to convert the percentage to a decimal (9.3% to 0.093) and remember that n = 12, since there are 12 months in a year.

Thus, we will need to solve for P to find Brad's deposit:

[tex]14832=P(\frac{0.093}{12})(^{12*3})\\14832=P(1.00775)^{36} \\14832=1.32038641P\\11233.07532=11233.08=P[/tex]

The function modelled for the given condition is [tex]y = -16x^{2} + 6x +22[/tex] and the time after which the skier is 5 feet above the water is 1.23 seconds.

A competitive water skier's heights y, x seconds after soaring off a ramp.

For x = 0, y = 22

for x = 0.25, y = 22.5

For x = 0.75, y = 17.5

For x = 1, y = 12

For x = 1.1, y = 9.24

The general equation of a quadratic equation is y = [tex]ax^{2} + bx +c[/tex]

Putting x = 0 and y = 22 in the equation, we get :

[tex]y = ax^{2} +bx +c[/tex]

c = 22

Now, putting x = 1 and y =12, we get,

12 = a*1 + b*1 + 22

a +b = 12 - 22 = -10 equation (1)

Putting x = 0.25, y = 22.5,

22.5 = a* [tex]22.5^{2}[/tex] +b*22.5 +22

506.25 a +22.5b = 0.5 equation(2)

Solving equation (1) and equation(2), we get :

a = -16 and b = 6 and c = 22

So, the quadratic equation becomes,

[tex]y = -16x^{2} + 6x +22[/tex]

Now, Time when the skier is 5 feet above the water,

[tex]x = \frac{3 +\sqrt{281} }{16} = 1.23 seconds[/tex]

Hence, the function modelled for the given condition is [tex]y = -16x^{2} + 6x +22[/tex] and the time after which the skier is 5 feet above the water is 1.23 seconds.

As Karen age is 52- year old and she is a female and her life insurance policy is for 20- years , then amount to be deducted from her life insurance paycheck is equal to $1317.

As given in the question,

Information given about Karen,

Age = 52- year old

Gender = female

Policy = 20 -year life insurance policy

Annual premium given per $1000 for coverage

Karen policy amount = $75,000

From the table it is given that,

Amount deducted per $1000 for 20year policy in the age limit of 48 -52

= $17.56

⇒ $1000 = $17.56

⇒ $75,000 = $( 17.56 × 75,000)/ 1000

                   = $1317.

By solving a linear equation we will see that there were 6 hours of labor.

We know that the total cost is composed by a fixed amount of $365 plus $89 per hour of labor, so if there are x hours of labor, the total cost will be:

c(x) =  $365 + x*$89

We know that the total cost is $899, then we can write the linear equation:

$899 = $365 + x*$89

$899 - $365 = x*$89

($899 - $365)/$89 = x = 6

For the given equation y  = 3x² -7x + 4 the vertex form is given by

( 7/6, -1/12).

As given in the question,

Equation is given by :

y  = 3x² -7x + 4

Standard form of the equation to get the vertex form is given by :

y = a ( x - h )² + k

Where ( h, k ) represents the vertex of the equation,

Now,

Simplify the given equation y  = 3x² -7x + 4 into standard form to get vertex form,

y  = 3x² -7x + 4

⇒ y = 3 [x² -2×(7/6)] + 4

⇒ y = 3 [ x² - 2×(7/6) + (49/36) - (49/36) ] + 4

⇒ y = 3 [ x² - 2×(7/6) + (49/36) ] - 3(49/36) + 4

⇒ y = 3 [x - (7/6)]² - (49/12) + 4

⇒ y = 3[x - (7/6)]² - (1/12)

Compare it with standard form ,

a = 3, h = (7/6) , k = -(1 /12)

Vertex form ( h, k) = ( 7/6 , -1/12 )

Therefore, for the given equation y  = 3x² -7x + 4 the vertex form is given by ( 7/6, -1/12).

What is Translation?

A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.

Given data ,

Let the 3 houses be A , B ,C

The coordinate of House A = A ( 1 , -1 )

​The coordinate of House B = B ( 1 , -2 )

The coordinate of House C = C ( 2 , -1 )

Now , the houses are relocated to new coordinates with

The new coordinate of House A = A' ( 3 , -4 )

The translation of Point A can be expressed in the form of x and y coordinate as there is a translation occurred with a scale factor

So ,

A ( x₁ , y₁ ) to A' ( x₂ , y₂ )

A ( 1 , -1 ) to  A' ( 3 , -4 )

x₂ = x₁ + 2

y₂ = y₁ - 3

From the figure , we can clearly see that the coordinates of the houses A , B and C are translated by a scale factor and the new coordinates are

x₂ = x₁ + 2

y₂ = y₁ - 3

Therefore ,

B ( x₁ , y₁ ) to B' ( x₂ , y₂ )

B' ( x₂ , y₂ ) = B' ( 3 , -5 )

C ( x₁ , y₁ ) to C' ( x₂ , y₂ )

C' ( x₂ , y₂ ) = C' ( 4 , -4 )

Hence , the new coordinates of House B and House C are B' ( 3 , -5 ) and C' ( 4 , -4 ) respectively

Answer:

x = 18. y = 54

Step-by-step explanation:

first we we figure out the degrees of the spot where N is.

(I know N references the line but ill be using it to call the spot)

72 + N = 90

subtract 72 from both sides

N = 18

So since opposite angles are the same

2x + N = 3x

2x + 18 = 3x

subtract 2x from both sides

18 = 1x

divide by 1 both sides

18 = x

______

now we add all the angles from the left sides to make 180

2x + N + 72 + y = 180

we know x is equal to 18 and N is also 18

2(18) + 18 + 72 + y = 180

simplify

36 + 18 + 72 + y = 180

add

126 + y = 180

subtract both sides by 126

y = 54
