Answer:

x = 58

Step-by-step explanation:

Given an angle outside a circle formed by a tangent and a secant then

angle = [tex]\frac{1}{2}[/tex] difference of the measures of the intercepted arcs, that is

51 = [tex]\frac{1}{2}[/tex] (160 - x) ← multiply both sides by 2

160 - x = 102 ( subtract 160 from both sides )

- x = - 58 ( multiply both sides by - 1 )

x = 58

Answer:

ANSWER[tex]q(x) = 7x + 4[/tex]

EXPLANATION

We want to find the quotient when [tex]7{x}^{2}-3x-9[/tex] is divided by x-1

We can quickly perform a synthetic division.

We write out the coefficients of the polynomial

[tex]7{x}^{2}-3x-9[/tex]

   7     -3     -9

1|         7      4

  7      4       -5

To obtain the top row.When we equate the divisor to zero, we get;[tex]x - 1 = 0[/tex][tex]\implies\:x=1[/tex]

This gives the 1 in the far left.The first two numbers in the last row are the coefficients of the quotient. The last number in the last row is the remainder.Therefore the quotient is [tex]7x + 4[/tex] and the remainder is -5

Remember this polynomial can be written as:

Dividend= Divisor * Quotient     + Remainder

[tex]7x^2-3x-9=(x-1)(7x+4)-5[/tex]

Therefore Quotient=7x+4

Answer:

Part 1) Option A. f of x equals one half times x plus 16

Part 2) Option  A. x = 5

Part 3) Option C. x − 4y = −9

Part 4) Option A. The number of rides is the independent variable, and the total cost is the dependent variable.

Step-by-step explanation:

Part 1)

Let

x -----> the number of months

y ----> vertical jump in inches

step 1

Find the slope

we have the points

(0,16) and (2,17)

[tex]m=(17-16)/(2-0)=\frac{1}{2}[/tex]

The equation of the line in slope intercept form is

[tex]y=mx+b[/tex]

we have

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

[tex]b=16[/tex] -----> the point (0,16) is the y-intercept

substitute

[tex]y=\frac{1}{2}x+16[/tex]

convert to function notation

f(x)=y

[tex]f(x)=\frac{1}{2}x+16[/tex]

Part 2) What is the equation of a line that contains the points (5, 0) and (5, −2)?

step 1

Find the slope

we have the points

(5, 0) and (5, −2)

[tex]m=(-2-0)/(5-5)=\frac{-2}{0}[/tex]

the slope is undefined

This is a vertical line (parallel to the y-axis)

therefore

The equation is

x=5

Part 3) Choose the equation that represents a line that passes through points (−1, 2) and (3, 1)

step 1

Find the slope

we have the points

(−1, 2) and (3, 1)

[tex]m=(1-2)/(3+1)=-\frac{1}{4}[/tex]  

step 2

Find the equation of the line into point slope form

[tex]y-y1=m(x-x1)[/tex]

we have

[tex]m=-\frac{1}{4}[/tex]

[tex]point\ (3, 1)[/tex]

substitute

[tex]y-1=-\frac{1}{4}(x-5)[/tex]

Convert to standard form

Multiply by 4 both sides to remove the fraction

[tex]4y-4=-(x-5)[/tex]

[tex]4y-4=-x+5[/tex]

[tex]x-4y=-4-5[/tex]

[tex]x-4y=-9[/tex]

Part 4) Jewels has $6.75 to ride the ferry around Connecticut. It will cost her $0.45 every time she rides. Identify the dependent variable and independent variable in this scenario

we know that

The independent variable is the variable whose change isn’t affected by any other variable (An example the age and time)

The dependent variable it’s what changes as a result of the changes to the independent variable (An example of a dependent variable is how tall you are at different ages. The dependent variable (height) depends on the independent variable (age))

Let

x ----> the number of rides

y ----> the total cost in dollars

In this problem

The independent variable or input is the number of rides

The dependent variable or output is the total cost

The correct linear function for Maryann's vertical jump is f(x) = ½x + 16. The equation of the line containing points (5, 0) and (5, −2) is x = 5. For the line through points (−1, 2) and (3, 1), the correct equation is 4x − y = −6, and in Jewels' scenario, the number of ferry rides is the independent variable, and the total cost is the dependent variable.

Answer:

$12,993.71

Step-by-step explanation:

The formula we want for this is exponential decay which is

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

where A(t) is the value of the car after the depreciation, a is the initial value of the car, r is the interest rate at which it depreciates in decimal form, and t is the time in years.  We have everything we need to fill in to solve for A(t):

[tex]A(t)=66,000(1-.15)^{10}[/tex]

We will do some simplifying first:

[tex]A(t)=66,000(.85)^{10}[/tex]

First raise .85 to the 10th power to get

A(t) = 66,000(.1968744043)

and then multiply to get

A(t) = $12,993.71

Answer:

  {52}

Step-by-step explanation:

The calculator function appears to be ...

  f(x) = {3x -1, x odd; x/2 +1, x not divisible by 4; x/4, x divisible by 4}

The inverse of the first function is ...

  x = 3y -1

  (x+1)/3 = y . . . . (y must be odd)

For x = 13, this is 14/3, which is not an integer.

__

The inverse of the second function is ...

  x = y/2+1

  2(x-1) = y . . . . (y must not be divisible by 4)

For x = 13, this is 2·12 = 24, which is divisible by 4, so 24 is not the input value.

__

The inverse of the third function is ...

  x = y/4

  4x = y . . . . (y must be, and is, divisible by 4)

For x = 13, this is 4·13 = 52.

The only possible input value for an output of 13 is 52.

Answer:

  24.5 cubic inches

Step-by-step explanation:

The formula for the volume of a cylinder is ...

  V = πr²h

A can with a diameter of 2.5 inches has a radius of 1.25 inches. Filling in the given values, the volume is ...

  V = π(1.25²)(5) = 7.8125π ≈ 24.54 . . . . cubic inches

The approximate volume is 24.5 cubic inches.

The volume of a cylinder is 24.54 inches³

The volume of a cylinder is equal to the product of the area of the circular base and the height of the cylinder. The volume of a cylinder is measured in cubic units.

We know that the volume of cylinder is

V = πr²h

Given that:

diameter = 2.5 inches

radius = 1.25 inches.

Height= 5 inches

V = π(1.25²)(5)

= 7.8125π

≈ 24.54 inches³

Hence, the volume of cylinder is 24.54 inches³

Answer:

  3022.08 . . . dollars per square meter

Step-by-step explanation:

The slope is multiplied by the factor that changes units:

  (280.76 dollars/ft²)×(1 ft²)/(.092303 m²) ≈ 3022.08 dollars/m²

To make predictions for house prices in square meters, you would have to multiply the given slope of 280.76 by the conversion factor of 1/0.092903, which will give an estimated slope of approximately 3017.9

The problem here is related to the conversion of units from square feet to square meters. Your friend gives you a simple regression fit for predicting house prices from square feet with an estimated intercept of -44850 and the estimated slope is 280.76.

Given that there are 0.092903 square meters in 1 square foot, a square foot equals to 1/0.092903 square meters. When you are making a prediction based on square meters rather than square feet, you need to consider this factor. This means the new slope would be calculated by multiplying the old slope with this conversion factor as:

Slope for prediction in square meters = Old slope * (1/0.092903) = 280.76 / 0.092903 = 3017.9 approximately.

We use absolute values to indicate this

|x − 37,500| ≤ 4,500

Answer:

|x − 37,500| ≤ 4,500

Step-by-step explanation:

Let x represents the new salary paid (In dollars ),

∵ The actual salary = $ 37,500

∵ Maximum difference in salaries = $ 4500

Case 1 : If x > 0

⇒ x - 37500 ≤ 4500 -----(1)

Case 2 : If x < 0

⇒ 37500 - x ≤ 4500

⇒ -(x-37500) ≤ 4500 -----(2)

By combining inequalities (1) and (2),

| x - 37500 | ≤ 4500  ( ∵ |a| < b ⇒ -a < b or a < b )

Answer:

[tex]y=-\frac{1}{7}x+\frac{37}{7}[/tex]

Step-by-step explanation:

Your equation is in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.  Your line has a slope of 7.  In order to find the line perpendicular to this line, we have to take the opposite reciprocal of the slope.  The perpendicular slope to m = 7 is m = -1/7.  Now we go through x = -5 and y = 6 to find the new equation.

6 = -1/7(-5) + b gives us

6 = 5/7 + b and

b = 37/7

Therefore, the equation of the line perpendicular to your original line is

[tex]y = -\frac{1}{7}x + \frac{37}{7}[/tex]

What is leap year?

A Leap Year has 366 days (the extra day is the 29th of February).

How to know if it is a Leap Year:

Leap Years are any year that can be exactly divided by 4 (such as 2016, 2020, 2024, etc)

How many galllons will a person drink in a leap year?

We have given,

Average person drinks 16 ounces of milk in 1 day.

We have to find milk consume by average person in 366 days in gallons.

We know, 1 ounce (oz)=0.01 gallons

So, 16 ounce = 16×0.01 gallons

Step-by-step explanation:

Answer:

h = 9 and k = -8

Step-by-step explanation:

Final answer:

By setting up an equation where the total costs for both electricians are equal and solving for h, we find that the number of hours for which the costs are the same is 4 hours.

Explanation:

To determine the number of hours, h, for which the cost would be the same for hiring both electricians, we set up an equation where both cost expressions are equal. The equation, which expresses the total cost for each electrician's services, is:

First electrician: Cost = $60 + $55h

Second electrician: Cost = $20 + $65h

We now equate the two expressions and solve for h:

$60 + $55h = $20 + $65h

$55h - $65h = $20 - $60

-$10h = -$40

Divide each side by -10: h = 4

Thus, the number of hours for which the costs are the same is 4 hours.

Final answer:

The number of hours for which both electricians would charge the same is 4 hours. We find this by setting up an equation based on their fees and hourly rates, solving this equation yields the result of 4 hours.

Explanation:

To determine the number of hours, h, for which the cost would be the same for hiring both electricians, we can set up an equation based on their charges. The first electrician charges a service call fee of $60 and $55 per hour. Therefore, the cost for the first electrician, C1, can be expressed as:

C1 = 60 + 55h

The second electrician charges a service call fee of $20 plus $65 per hour, which means the cost for the second electrician, C2, is:

C2 = 20 + 65h

To find when the costs are the same (C1 = C2), we set the two expressions equal to each other:

60 + 55h = 20 + 65h

Now we solve for h:

60 + 55h = 20 + 65h

55h - 65h = 20 - 60

-10h = -40

h = 4

The costs are the same when the electricians work for 4 hours.
