Billy left home at 9 a.M. And rode his bicycle to the park at an average speed of 10 miles per hour here I got the park at 9:30
tamaranim1 [39]

Answer:

Park is <u>5 miles</u> from Billy's home.

Step-by-step explanation:

Given:

Billy left home at 9 a.m. And rode his bicycle to the park at an average speed of 10 miles per hour here and got the park at 9:30 a.m.

Now, to find the distance from park to Billy,s home.

Time it took Billy to rode his bicycle from park to home is from 9.30 a.m to 9.30 p.m.

So, the time = (9.30 - 9.00) = 30 minutes

=\frac{30}{60}  =0.5\ hour.

Speed = 10 miles per hour.

Now, to get the distance from park to Billy's home we put formula:

Distance=Speed\times Time.

Distance=10\times 0.5

Distance=5\ miles.

Therefore, park is 5 miles from Billy's home.

THE NUBER OF PEOPLE CONTACTED
Elis [28]

Answer:

option c, x = 3

Step-by-step explanation:

Given:

  • f(x) = 27
  • f(x) = 3^{x}

Since both equal f(x) they must be equivalent as well,

3^{x} = 27\\

Apply exponent rule, 3 x 3 x 3 = 27

hence x = 3

Given f(x) = x² - 10x + 22, what is the range of f?
adoni [48]

Answer:

[-3, ∞)

Step-by-step explanation:

There are many ways to find the range but I will use the method I find the easiest.

First, find the derivative of the function.

f(x) = x² - 10x + 22

f'(x) = 2x - 10

Once you find the derivative, set the derivative equal to 0.

2x - 10 = 0

Solve for x.

2x = 10

x = 5

Great, you have the x value but we need the y value. To find it, plug the x value of 5 back into the original equation.

f(x) = x² - 10x + 22

f(5) = 5² - 10(5) + 22

      = 25 - 50 +22

      = -3

Since the function is that of a parabola, the value of x is the vertex and the y values continue going up to ∞.

This means the range is : [-3, ∞)

Another easy way is just graphing the function and then looking at the range. (I attached a graph of the function below).

Hope this helped!
