As an estimation we are told 5 miles is 8km convert 112km to miles

Answer:

-x² - 3

Step-by-step explanation:

If a function is concave down, that means the x value is negative.

Hence we know that it should be -x²

The graph is translated 3 units down

Hence:

-x² - 3

Answer:

mΔ1 = 42°

mΔ2 = 42°

Step-by-step explanation:

Δ1 + 138° = 180°

Δ1 = 180° - 138°

Δ1 = 42°

Δ2 + 138° = 180°

Δ2 = 180° - 138°

Δ2 = 42°

Answer:

y = - 3x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

3x + y = 3 ( subtract 3x from both sides )

y = - 3x + 3 ← in slope- intercept form

Answer:

y=-3x+3

Step-by-step explanation:

3x+y=3

y=3-3x

y=-3x+3

Answer:

The highest rate of birds is during the years 4 to 3

(remember that the lowest digit of number of negative is the highest and the highest is the lowest)

Step-by-step explanation:

Rate of Changes:

1 to 2: 5080.86 - 5238/ 2 - 1

=  -157.14/1

= (convert to decimal) -157.1

2 to 3: 4928.43 - 5080.86/ 3 - 2

= -152.43/ 1

= -152.43

3 to 4: 4780.58 - 4928.43/ 4 - 3

= -147.85/ 1

= -147.85

Answer:

40.5 square feet

Step-by-step explanation:

The formula for finding the area of a rhombus is (diagonal 1 x diagonal 2)/2. Since you're given the side of the rhombus, you can use the 45:45:90 degree triangle rule where the measure of the sides is 1:1:[tex]\sqrt{2}[/tex] to find the diagonals  (both equal 9 feet).

9x9/2 = 81/2 = 40.5 [tex]ft^{2}[/tex]

Answer:

There is no graph but the graph that would have a straight line

Answer:

Whichever line is straight and does not have x repeat itself is considered linear.

Step-by-step explanation:

A linear function can be shown by using the equation y=mx+b, in which m is the slope and b is the y-intercept. A linear function must be able to follow this formula in order to be considered linear. An exponential equation, quadratic equation, or other equation will not work.

Chances are, if the line is straight and the points plotted can be connected within a straight line and not overlap, they are a linear function.

[A function being an equation in which x does not repeat itself, therefore a vertical line up and down is not considered a linear function, however, a horizontal line is.]

Answer:

1105.84 in³

Step-by-step explanation:

The volume of the wheel can be obtained using the formular for the volume of a cylinder :

V = πr²h ;

Height, h = 5.5 in

Radius, r = 8 in

V = π * 8² * 5.5

V = π * 64 * 5.5

V = π * 352

Volume of wheel = 1105.8406 in³

Answer:

67.50

Step-by-step explanation:

If he makes 4.5 percent on each tab, 149.99x .045 is 6.75 per tablet. 6.75 times 10 is 67.50

Answer: $67.50

Steps:

149.99 * .045 = 6.75

6.75 * 10 = 67.50

Answer:

No

Step-by-step explanation:

10 kilograms = 22 pounds

23 kilograms = ? pounds

so for this you would need to cross multiply:

(22 * 23) = 506

(10 * x ) = 10x

--> 506 = 10x

Next step is to isolate the varible (x), to do that you need to divide by 10.

x = 506/10 = 50.6

50.6lbs is more than 50lbs so no it can't get checked out

No, Brianna is not correct.

The distance around the pool is 131.4 ft

The perimeter of a semicircle is the sum of half of the circumference of the circle and its diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius, and, 2r=d is diameter.

P=(πr + 2r)

here, we have,

1) Semi circle with a diameter equal to the side opposite it, 20 ft.

Find the length of half the circle:

Circumference of semi-circle = (1/2)(πd)

Where:

π = 3.14

d = 20 ft.

Circumference of semi-circle = (1/2)(3.14)(20 ft) = 31.4 ft.

2) Vertical lengths from the endpoint of semi-circle to the endpoints of horizontal lengths, 40 ft each ⇒ 2 × 40 ft. = 80 ft.

3.) Horizontal length at 20 ft.

Add the semi-circle, vertical, and horizontal lengths:

Distance around the pool = 31.4 ft + 80 ft. + 20 ft.

Distance around the pool = 131.4 ft.
