A rectangle has an area of 226.1 square miles and a base of 13.3 miles. What is the height?
miskamm [114]

Answer:

The width (in our case it is the height) of the rectangle equals 17 miles

Step-by-step explanation:

In order to solve this, we need to know the following...

Area of a rectangle = Length x Width

(in our case based on what you said length is the base and width is the height)

Now we just change the formula to our needs and get that...

Width = Area of the rectangle / Length

And so we get...

Width = Area of the rectangle / Length

Width = 226.1 / 13.3

Width = 17 miles

For the function f(x) and g(x) given in the graph. Find f(g(2))
Katen [24]

Answer:

f(g(2)) = 4

Step-by-step explanation:

find g(2) then substitute the value obtained into f(x)

locate x = 2 on the x- axis, go vertically up to meet g(x) at (2, 5 )

locate x = 5 on the x- axis, go vertically up to meet f(x) at (5, 4 )

then f(g(2)) = 4

If f ( x ) f ( x ) is a linear function, f ( − 5 ) = 0 f ( - 5 ) = 0 , and f ( 2 ) = 4 f ( 2 ) = 4 , find an equation for f ( x
Effectus [21]

Answer:

f(x) = 4/7x + 20/7

Step-by-step explanation:

If we were to graph this function, we would see that the two points would be, (-5, 0), and (2, 4). First, we have to find the slope, which is equal to:

<u>(first y-coordinate - the second y coordinate)</u>

(first x-coordinate - second x coordinate)

= <u>(0 - 4)</u>

   (-5 - 2)

= -4/-7 = 4/7. now, we multiple -5 by 4/7 and get -20/7. we have to add 20/7.

Thus, the answer is f(x) = 4/7x + 20/7
