What is the inverse of the function f(x) = 2x - 10?

Answer:

A. 190 inches

Step-by-step explanation:

Plug in the numbers to the surface area formula  to get 190, i messed up last time

Answer:

55.9 mph

Step-by-step explanation:

190/3.4 = 55.88 mph rounded to one dp = 55.9 mph

A car travels a distance of [tex]190[/tex] miles in a time of [tex]3.4[/tex] hours, then  its average speed will be  [tex]56[/tex] miles per hour.

Average speed is speed is the total distance traveled by the car in a particular time of interval.

Average speed [tex]=\frac{Total \ Distance}{Total \ Time}[/tex]

We have,

Distance [tex]=190[/tex] miles

Time[tex]= 3.4[/tex] hours

So, Using the above given formula,

Average speed [tex]=\frac{Total \ Distance}{Total \ Time}[/tex]

                          [tex]=\frac{190}{3.4}[/tex]

                         [tex]=56[/tex] miles per hour

So, the average speed of car is [tex]56[/tex] miles per hour which is find out using the above given formula.

Hence, we can say that if a car travels a distance of [tex]190[/tex] miles in a time of [tex]3.4[/tex] hours, then  its average speed will be  [tex]56[/tex] miles per hour.

Answer:

7.9 m

Step-by-step explanation:

Use the Pythagorean theorem: a²+b²=c²

This formula can be used to solve a side of any right (90°) triangle.

c² is the length of the hypotenuse (the diagonal side of the triangle, opposite to the 90° angle)

So, c = 32m.

Sides a and b are the legs of the triangle, but we only know one side. Plug numbers into the formula:

31² + b² = 32²

961 + b² = 1024 Subtract 961 from both sides to get b² by itself.

b² = 63

√b² = √63  Square root both sides to get b by itself.

b = 7.93725

Answer is 7.9 meters, rounded to tenths place

28/8=3.5

therefore 6*3.5 = x

Answer:

The answer is 21

Step-by-step explanation:

If you do 28/8 you get 3.5. So he used 3 1/2 blueberries. Then you have to times 6 by 3.5 to get 21. Put it back into ratio form and you get 28:21

Answer:

.4321

Step-by-step explanation:

move the decimal to the left four times

We want to write four thousand three hundred twenty-one ten thousandths as a decimal​.

The number is:

4321.010

To do it, we need to understand what each place value represents, where the place values are the place of each digit in reference to the decimal point.

And for the right we have:

Of course, it continues in both ways, but this is enough to write our number.

We have:

"four thousand..."

Then the fourth digit at the left is a 4.

"... three hundred..."

The third digit is a 3.

"...twenty-one..."

The second digit is a 2, and the first is a 1.

For the right side, we do not have tenths, so the first digit at the right is a zero.

And "...ten thousandths"

We have a "10" in the second and third digits at the right of the decimal point.

Then our number is:

4321.010

Answer:

15,600,000

Step-by-step explanation:

We start with our initial population of 600,000. Then multiply that with the rate of 4% (0.04 in decimal, or 1.04 so that the 0.04 is automatically added to the 600,000.)

Step-by-step explanation:

Given

f(x) = 6x - 5

f^-1(x) = ?

Let

y = f(x)

y = 6x - 5

Interchanging the roles of x and y we get

x = 6y - 5

6y = x + 5

y = ( x + 5 ) / 6

So therefore f^- 1(x) = (x + 5) / 6

Answer:

Tallest = Morgan

Shortest = Suzanna

Step-by-step explanation:

Assuming Latisha = 1

0.8 is less than 1, meaning it's 80% the height of Latisha, so this means Suzanna is shorter than Latisha.

1.09 is more than 1, Morgan is taller than Latisha.

Morgan is tallest and Suzanna is shortest, Latisha in the middle.
