Alyssa is jogging near Central Park. She runs along 65th Street for about 0.19 miles, turns right and runs along Central Park West for about 0.28 miles. She then turns right again and runs along Broadway until she reaches her starting point. How long is her total run to the nearest hundredth of a mile?

I never came across a question like this one. Time to reason my way to the answer.

We know that f(x) = y.

In the point given, y = 8.

So, f(x) - 2 = y - 2 = 8 - 2 = 6.

The corresponding point should be (-5, 6).

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]

Answer:

vertex is (4,-4) and another point is (6,0) or you could use (2,0) or many other options :)

Step-by-step explanation:

The cool thing about this question your quadratic is in factored form so your x-intercepts are easy to figure out, they are 2 and 6.

So you can plot (6,0) and (2,0).

The vertex will lie half between x=2 and x=6... so it lays at (6+2)/2=4

We just have to find the y-coordinate for when x=4.

Plug in 4 gives you (4-2)(4-6)=(2)(-2)=-4.

So the vertex is at (4,-4).

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:

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.

We know that tangent of circle is a straight line that touches the circle exactly at one point. This point is known as point of tangency.

Upon looking at our given diagram, we can see that line segment RX touches circle A exactly at one point that is X. Line segment SX touches circle A exactly at one point that is X, therefore, line segment RS is tangent to our given circle.

Similarly, line segments SQ and TQ touch circle A exactly at one point that is Q, therefore, line segment ST is tangent to our given circle.

We can see that line segments RP and TP touch circle A exactly at one point that is P, therefore, line segment ST is tangent to our given circle.

AP is radius of circle, therefore, AP is not a tangent for our given circle.

If we draw a line joining points XT, it will intersect circle at two points, therefore, XT is not a tangent for our given circle.

I(- 5, 10) → I'(10, - 5)

J(28, - 14) → J'(- 14, 28)

B represents the image coordinates of H, I, J

For the given figure with vertices H(17,34), I(-5,10), and J(28,-14) across the line y=x, the reflection will appear at H(34,17), I(10,-5), J(28,-14). This is because at y=x the reflection will have the coordinates with interchanged values.

Across y=x, the reflection will have interchanged coordinates.

that is (x, y) → (y, x)

For the given vertices across the line y=x,

H(17,34) → H'(34,17)

I(-5,10) → I'(10,-5)

J(28,-14) → J'(-14,28)

So, option (2) is correct that is H(34,17), I(10,-5), J(-14,28) which undergoes reflection across y=x.

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.

as much as means less than or equal to

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 )

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.
