A car traveled at a constant speed. The graph shows how far the car traveled, in miles, during a given amount of time, in hours.

snow_tiger [21]

Answer:

Step-by-step explanation:

A car traveled at a constant speed as shown in the graph.

Distance traveled is on the y-axis and duration of travel on the x-axis.

Point A(3.5, 210) shows,

Distance traveled = 210 miles

Time to travel = 3.5 hours

So the point (3.5, 210) shows the distance traveled by the car in 3.5 hours is 210 miles.

Slope of the line = speed of the car = $\frac{\text{Distance traveled}}{\text{Time}}$

= $\frac{210}{3.5}$

= 60 mph

Now we will find the speed of the car at another point B(1, 60).

If the speed of car is same as the point B as of point A, point B will lie on the graph.

Speed of the car at B(1, 60) = $\frac{\text{Distance traveled}}{\text{Time}}$

= $\frac{60}{1}$

= 60 mph

Hence, we can say that point B(1, 60) lies on the graph.

Answer:

1 / q^3 = 1 / q^n

n = - 3

Step-by-step explanation:

1/r^-4 = r^4

p^3 * q^2 * p^4 * q^n * r^3 * r^4 = p^7 q ^5 r^7

(p^3 * p^4 *q^2 * r^3 * r^4 ) / ( p^7 * q^5 * r^7) = 1/q^n

(p^7 * q^2 * r^7) / (p^7 * q^5 * r^7) = 1/q^n

q^2 / q^5 = 1/q^n

1 / q^3 = 1 / q^n

The first and last terms of a 52-term arithmetic series are listed in the table. What is the sum of the series?

inna [77]

sum = x(n+1)/2

where x is the number of the term ( in this case 52)

n is the last number in the series( which is not given in the problem)

Andrea is painting a ceramic plate with a diameter of 12 inches. She wants to paint a thin blue line around the edge of the plat

mihalych1998 [28]

Answer:

37.7 inches

Step-by-step explanation:

She wants to paint the line along the circumference of the plate.

The plate is circular; the circumference of a circle is given as:

C = πD

where D = diameter

The diameter of the plate is 12 inches, therefore:

C = π * 12 = 37.7 inches

The line will be 37.7 inches long.
