To find out the cyclist's average speed you simply have to divide 50.0km by 2.5 to find the answer. Therefore the cyclist's average speed is 20.0 km an hour.

Answer is 20.0 km per hour.

<em>Explanation;</em>

S = d/t

Where, S is the speed, d is the distance and t is the time taken.

Here,

d = 50.0 km

t = 2.5 hours

By applying the formula,

S = 50.0 km / 2.5 hours

= 20.0 km per hour

Hence, the average speed of the cyclist is 20.0 km per hour.

Which equation represents the line that is perpendicular to y = 1/4 and passes through (-6,-9)

cluponka [151]

Answer:

Step-by-step explanation:

y = $\frac{1}{4}$ is the equation of a horizontal line parallel to the x- axis.

A line perpendicular to it will be a vertical line parallel to the y- axis with equation

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (- 6, - 9 ) with equation

x = - 6 → B

Since 1972 the US. inflation rate has averaged 4.8 % per year . Use the approximate doubling time formula to estimate the doubli

Artemon [7]

Answer:

14 3/4 years

Step-by-step explanation:

Let's assume compound inflation. The appropriate formula for that is:

A = P(1 + r)^t.

If we represent current prices by P, then double that would be 2P:

2P = P(1 + 0.048)^t Find t, the time required for prices to double.

Then:

2 = 1.048^t

Taking the natural log of both sides, we get:

ln 2 = t·ln 1.048, so that:

t = (ln 2) / (ln 1.048) = 14.78

At 4.8 inflation, with annual compounding, prices will double in approx. 14 3/4 years.
