Answer:

The value of f(3) is -2.

Step-by-step explanation:

This is a recursive function. So

[tex]f(1) = 2[/tex]

Now, we find f(2) in function of f(1). So

[tex]f(1+1) = f(1)^2 - 3[/tex]

[tex]f(2) = f(1)^2 - 3 = 2^2 - 3 = 1[/tex]

Now, with f(2), we can find the value of f(3).

[tex]f(2+1) = f(2)^2 - 3[/tex]

[tex]f(3) = f(2)^2 - 3 = 1^2 - 3 = -2[/tex]

The value of f(3) is -2.

Answer:

The width of the TV screen is 56 inches.

Step-by-step explanation:

We can find the width of the TV screen by using Pitagoras:  

[tex] D^{2} = H^{2} + W^{2} [/tex]

Where:

D: is the diagonal = 65 in

H: is the height = 33 in

W: is the width =?

Then, the width is:

[tex] W = \sqrt{D^{2} - H^{2}} = \sqrt{(65 in)^{2} - (33 in)^{2}} = 56 in [/tex]

Therefore, the width of the TV screen is 56 inches.

The slope of the given linear equation is 3.75.

Given that, the graph given shows a linear representation of a jogger’s heartbeat in beats per minute, as his speed is increased (in feet per second).

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.

From the given graph we have the coordinates (6, 80) and (10, 95).

The slope of an equation = (y2-y1)/(x2-x1)

=(95-80)/(10-6)

=15/4

=3.75

Therefore, the slope of the given linear equation is 3.75.

Answer:

[tex]L =52[/tex] --- Lower Limit

[tex]U =82[/tex] --- Upper Limit

Step-by-step explanation:

Given

[tex]N = 10[/tex]

[tex]Data: 74, 73, 77, 77, 71, 68, 65, 77, 67, 66[/tex]

Required

Determine the lower and upper limits of box and whisker display

First, arrange the data in ascending order

The sorted data is:

[tex]Data: 65, 66, 67, 68, 71, 73, 74, 77, 77, 77[/tex]

The lower limit (L) is calculated using:

[tex]L = Q_1 - 1.5 * (Q_3-Q_1)[/tex]

The upper limit (U) is calculated using:

[tex]U =Q_3 + 1.5 * (Q_3-Q_1)[/tex]

Q1 is calculated using:

[tex]Q_1 = \frac{1}{4}(N+1)[/tex]

[tex]Q_1 = \frac{1}{4}(10+1) = 2.75 = 3rd\ data[/tex]

[tex]Q_1 = 67[/tex]

Q3 is calculated using:

[tex]Q_3 = \frac{3}{4}(N+1)[/tex]

[tex]Q_3 = \frac{3}{4}(10+1) = 8.25= 8th\ data[/tex]

[tex]Q_3 = 77[/tex]

So:

[tex]L = Q_1 - 1.5 * (Q_3-Q_1)[/tex]

[tex]L =67 - 1.5*(77-67)[/tex]

[tex]L =67 - 1.5*10[/tex]

[tex]L =67 - 15[/tex]

[tex]L =52[/tex]

[tex]U =Q_3 + 1.5 * (Q_3-Q_1)[/tex]

[tex]U =67 + 1.5*(77-67)[/tex]

[tex]U =67 + 1.5*10[/tex]

[tex]U =67 + 15[/tex]

[tex]U =82[/tex]

Answer:

y-intercept=5

x-intercept=-2

Step-by-step explanation:

To find the y intercept, plug in 0 for x. So you get 10(0)-4y=-20. Simplify, and clear out the negatives on both sides because they cancel each other out. 4y=20 would be your final equation. y=5.

To find the x intercept, you plug in 0 for y this time. The equation is 10x-4(0)=-20. Simplify to get, 10x=-20. You cannot remove the negative because there isn't a negative sign on the 10x. -20/10 is -2.

l = 15.9

P = 2(8.2) + 2(8.2) = 32.8

Surface Area:

SA = B + L

B = (8.2)(8.2) = 67.24

Answer:

a square and rectangle have the same perimeter. the length of the rectangle is 4 cm less than twice the side of the square, and the width of the rectangle is 6 cm less than the side of the square.

Step-by-step explanation:

jayfeather friend me

The required side length of the square is 5 cm.

A rectangle is a part of a quadrilateral, whose sides are parallel to each other and equal.

Given that,

Length of rectangle = 7 cm,

Width of rectangle = 3 cm.

The perimeter of rectangle = 2(length + width)

                                             = 2(7 + 3)

                                             = 2 x 10

                                             = 20

Also, given that the perimeter of the rectangle is equal to the perimeter of a square,

Let side of square is a then perimeter = 4a

⇒ 4a = 20

⇒ a = 5

The side length of the square is 5 cm.

You will need approximately 1.33 gallons of paint to cover the four walls with one coat, not including the windows and the door.

Given that,

Room dimensions:

Length: 16 feet

Width: 10 feet

Height: 8 feet

Features on the walls:

Two windows:

Width: 2 feet

Height: 5 feet

One door:

Width: 4 feet

Height: 7 feet

Paint coverage:

1 gallon of paint covers 350 square feet

Calculate the area of the walls first:

Subtract the area of the windows and door area from the total wall area.

The total wall area is the sum of the areas of all four walls.

The area of each wall is calculated by multiplying the height of the room by its length.

So, the area of each wall = 8 feet (height) x16 feet (length)

The area of each wall = 128 square feet.

Calculate the area of the windows and the door.

The area of each window is calculated by multiplying its width by its height.

So, the area of each window = 2 feet (width) x  5 feet (height)

The area of each window = 10 square feet.

The area of the door is calculated by multiplying its width by its height. So,

The area of the door = 4 feet (width) x 7 feet (height)

The area of the door  = 28 square feet.

Now, subtract the total area of the windows and the door from the total wall area.

Total wall area = 4 walls x 128 square feet

Total wall area  = 512 square feet

The total area of the windows = 2 windows x 10 square feet

The total area of the windows = 20 square feet

The total area of the door = 1 door x 28 square feet

The total area of the door = 28 square feet

Area to be painted = Total wall area - Total area of the windows - Total area of the door

Area to be painted = 512 square feet - 20 square feet - 28 square feet

Area to be painted = 464 square feet.

Now, we can determine the number of gallons of paint needed.

Since 1 gallon of paint covers 350 square feet,

Divide the area to be painted by 350.

The number of gallons of paint needed = Area to be painted / Coverage per gallon

The number of gallons of paint needed = 464 square feet / 350 square feet/gallon

The number of gallons of paint needed ≈ 1.33 gallons.

Hence, you will need approximately 1.33 gallons of paint to cover the four walls with one coat, not including the windows and the door.

Step-by-step explanation:

Rearranging the slope-intercept for equation, we can find the intercept:

  y = mx +b

  y -mx = b . . . . . subtract mx

We know the slope of the parallel line is the same as that of the given line (m=4), so we only need to find 'b'.

  b = 9 -4(4) = -7

The desired equation is ...

Answer:

x ≥ 7

Step-by-step explanation:

First, put the same terms on the same side. So subtract 5 from both sides. You will get:

-3x ≤ -21

Divide both sides by -3 to get x alone. When dividing, the inequality sign will change to the opposite. So it will go from a (less than or equal to) sign to a (greater than or equal to) sign.

You will get:

x ≥ 7

Therefore, x will be a number that is greater than or equal to 7.

Answer:

a. 54.05 Mpbs.

b. 2.745... standard deviations.

c. The z-score is 2.745....

d. The carrier's highest data speed is significantly high.

Step-by-step explanation:

a. The difference between the highest measured data speed and the mean is 72.6 - 18.55 =  54.05 Mbps.

b. The amount of standard deviations of 54.05 Mbps is equal to this value divided by the standard deviations, so we yield [tex]\frac{54.05}{19.69} = 2.745...[/tex] standard deviations.

c. The z-score is equal to the difference between the mean and a data point in standard deviations, so the z-score is 2.745....

d. 2.745... is not between -2 and 2, so the carrier's highest data speed is not insignificant - so it's significantly high.
