Rearrange this to solve for x first:

$x=12tan(46)$ then plug it into your calculator to get

x = 12.4

Make sure your calculator is in degree mode and not radian mode!

Step-by-step explanation:

Use the power of a power property.

$(2^{-7}*5^{5} )^{2}$

Multiply all the exponents in the parenthesis by 2.

$(2^{-7}*5^{5} )^{2}=(2^{-14}*5^{10} )$

The answer is B. $2^{-14}*5^{10}$ .

Given f(x) = 4x + 2, find f-1(3).

Alexxandr [17]

Answer:

1/4

Step-by-step explanation:

The inverse function tells you the input value that corresponds to the given output value of the function.

<h3>Application</h3>

You want f^-1(3), which is the value of x such that f(x) = 3.

f(x) = 3 = 4x +2

1 = 4x . . . . . . subtract 2

1/4 = x . . . . . divide by 4

The inverse function of 3 is 1/4:

$\boxed{f^{-1}(3)=\dfrac{1}{4}}$

Wendy borrowed a 370-page book from the library. She has already read 20 pages. The book is due back to the library in 7 days. W

Leviafan [203]

Answer:

n ≥ 50

Step-by-step explanation:

Total pages = 370

Read pages = 20

Number of days remaining = 7

Reading rate per day = n

7n + 20 ≥ 370

7n ≥ 370 - 20

7n ≥ 350

n ≥ 350/7

n ≥ 50 pages per day for the remaining 7 days
