If you double 16 you get the answer to 8*4 (Which is 32)

madreJ [45]3 years ago

Answer:

The answer is 2 and 8

Step-by-step explanation:

First let us find the value of 8*4

8*4 = 32

Second let us find two numbers that we can correctly multiply to give half of 32 I.e 16.. Say 8 and 2

Hence 8*2=16

So that when we double 16 we have 32

I.e

16*2=32

Find the inverse of the given function.
kodGreya [7K]

For this case we must find the inverse of the following function:

f (x) = - \frac {1} {2} \sqrt {x + 3}

We follow the steps below:

Replace f(x) with y:

y = -\frac {1} {2} \sqrt {x + 3}

We exchange the variables:

x = - \frac {1} {2} \sqrt {y + 3}

We solve for "y":

- \frac {1} {2} \sqrt {y + 3} = x

Multiply by -2 on both sides of the equation:

\sqrt {y + 3} = - 2x

We raise both sides of the equation to the square to eliminate the radical:

(\sqrt {y + 3}) ^ 2 = (- 2x) ^ 2\\y + 3 = 4x ^ 2

We subtract 3 from both sides of the equation:

y = 4x ^ 2-3

We change y by f ^ {- 1} (x):

f ^ {- 1} (x) = 4x ^ 2-3

Answer:f ^ {- 1} (x) = 4x ^ 2-3

(please!!!) What fraction is equivalent to 38%?
Aleks04 [339]

Answer: 19/50

Step-by-step explanation: To write a percent as a fraction in lowest terms, first remember that a percent is a ratio that compares a number to 100. In this case, 38% can be written as the ratio 38 to 100 or 38/100. Notice however that 38/100 is not in lowest terms so we need to divide the numerator and denominator by the greatest common factor of 38 and 100 which is 2.

38 ÷ 2 = 19

100 ÷ 2 = 50

<em>Therefore, 38% can be written as the fraction 19/50 which is in lowest terms.</em>
