Answer:

The average speed for the whole rally is <u>45 miles per hour</u>.

Step-by-step explanation:

Given:

You have traveled 30 miles east and then 30 miles north. To get back to the start, I travel 30 miles west in 1 hour and then 30 miles south in a half hour.

Now, to find the average speed for the whole rally.

So, for getting the speed of 30 miles west in 1 hour.

By putting formula:

Speed = \frac{distance}{time}

Speed = \frac{30}{1}

Speed = 30\ miles\ per\ hour

Now, to get the speed of 30 miles south in half hour same way as above:

Speed=\frac{30}{0.5}

Speed = 60\ miles\ per\ hour

Then, to get the average speed.

We calculate the average of both the speed:

Average=\frac{30+60}{2}

Average=\frac{90}{2}

Average=45 miles\ per\ hour.

Therefore, the average speed for the whole rally is 45 miles per hour.

Charlotte measures the distance from the center of a circular garden to its edge and finds it is 43 meters. How long is the path
yanalaym [24]

Answer: 270.29 meters

Step-by-step explanation:

This is a circle which means that the distance that Charlotte measured from the center of a circular garden to its edge is the radius.

The length of the path which goes around the garden would therefore be the circumference.

Circumference = π * diameter

Diameter = radius * 2

= 43 * 2

= 86 meters

Circumference = 22/7 * 86

= 270.29 meters

Consider the graph of the function f(x)=2x.
77julia77 [94]

Given:

The parent function is:

f(x)=2^x

The other function is:

g(x)=2f(x)

To find:

The statement that describes a key feature of function g.

Solution:

We have,

f(x)=2^x

g(x)=2f(x)

Using these two functions, we get

g(x)=2(2)^x

Putting x=0, we get

g(x)=2(2)^{(0)}

g(x)=2(1)

g(x)=2

The y-intercept of the function g at (0,2). So, option A is correct and option B is incorrect.

We know that g(x)\to 0 as x\to -\infty and it will never intersect the line y=0. It means the horizontal asymptote of the function g is

Therefore, the correct option is A.
