Use f(x) = 1/2 x and f -1(x) = 2x to solve the problems. f(2) = 1 f−1(1) = 2 f−1(f(2)) = 2 f−1(−2) = f(−4) = f(f−1(−2)) =

vampirchik [111]

Answer:

In this problem, we are given the following functions:

$f(x)=\frac{1}{2}x$

and its inverse function:

$f^{-1}(x)=2x$

First of all, we want to calculate $f(2)$ . This can be obtained by substituting

x = 2

into f(x). Doing so, we find:

$f(2)=\frac{1}{2}\cdot 2 = 1$

Then we want to calculate $f^{-1}(1)$ . We can do it by substituting

x = 1

into $f^{-1}(x)$ . Doing so,

$f^{-1}(1)=2\cdot 1 = 2$

Then we want to calculate $f^{-1}(f(2))$ , which can be found by calculating f(2) and then using it as input for $f^{-1}(x).$ We know that

f(2) = 1

Therefore,

$f^{-1}(f(2))=f^{-1}(1)=2$

Then we want to calculate $f^{-1}(-2)$ , which can be calculated by plugging

x = -2

into $f^{-1}(x)$ . Doing so,

$f^{-1}(-2)=2\cdot (-2)=-4$

Then we want to calculate $f(-4)$ ; by substituting

x = 4

into f(x), we find

$f(-4)=\frac{1}{2}\cdot (-4)=-2$

Finally, we want to find $f(f^{-1}(-2))$

We know already that

$f^{-1}(-2)=-4$

So we have:

$f(f^{-1}(-2))=f(-4)=-2$

If 7.5% of pizza orders in gotham are for hawaiian pizzas, and you know that there are 100 pizza restaurants in gotham, what can

LUCKY_DIMON [66]

Answer: There are approximately 8 restaurants that have hawaiian pizzas on their menus.

Step-by-step explanation:

Total number of pizzas restaurants in Gotham = 100

Percent of pizza orders in Gotham are for hawaiian pizzas = 7.5

Number of Gotham restaurants that have hawaiian pizzas on their menus is given by

$7.5\%\text{ of} 100\\\\=\frac{7.5}{100}\times 100\\\\=7.5$

So, there are approximately 8 restaurants in Gotham that have hawaiian pizzas on their menus.

eduard

Answer:

The banner is 10 2/3 ft long

Step-by-step explanation:

1 1/3 = 4/3 times the width of the banner:

4/3 * 8 feet wide = 4/3 * 8 = 32/3 = 10 2/3 feet long

The banner is 10 2/3 feet long. :)

Which value would be a solution for x in the inequality 47-4x<7

cluponka [151]

Answer:

x > 10

Step-by-step explanation:

47-4x<7

Subtract 47 from each side

47-47-4x<7-47

-4x < -40

Divide by -4. When dividing by a negative, flip the inequality.

-4x/-4 > -40/-4

x > 10

Is that not right? or am I just wrong cause it says that it is not right please help

RideAnS [48]

Answer:

98 cm²

Step-by-step explanation:

The area of a circle is:

$A=\pi r^2$

A semicircle is half a circle therefore the area of a semicircle would be:

$A=\frac{1}{2}\pi r^2$

We can plug in the given values into the equation:

$A=\frac{1}{2}*3.142*(7.9)^2\\A=\frac{1}{2}*3.142*62.41\\A=\frac{1}{2}*196.09222 \\A=98.04611$

We need to round to TWO sigfigs meaning...

$A=98 \ cm^2$

Sigfig rules:

Nonzero numbers are significant

Trailing zeros are significant (only if there is a decimal point)

Any sandwiched zero is signification (Ex: 405 --> 3 sigfigs)
