KengaRu [80]3 years ago
3 0

Answer:

\frac{1}{25}

Step-by-step explanation:

Using the rule of exponents

a^{-m} = \frac{1}{a^{m} }, hence

f(- 2) = 5^{-2} = \frac{1}{5^{2} } = \frac{1}{25}

How do you use proportions to solve percent problems​
exis [7]

Answer:

Step-by-step explanation:

EXAMPLE #1:

What number is 75% of 4?   (or   Find 75% of 4.)

The PERCENT always goes over 100.

   (It's a part of the whole 100%.)

4 appears with the word of:

   It's the WHOLE and goes on the bottom.

A proportion showing one fraction  with PART as the numerator and 4 as the denominator equal to another fraction with 75 as the numerator and 100 as the denominator.

We're trying to find the missing PART (on the top).

In a proportion the cross-products are equal:   So 4 times 75 is equal to 100 times the PART.

The missing PART equals 4 times 75 divided by 100.

(Multiply the two opposite corners with numbers; then divide by the other number.)

4 times 75 = 100 times the part

300 = 100 times the part

300/100 = 100/100 times the part

3 =   the part

A proportion showing the denominator,  4, times the diagonally opposite 75; divided by  100.

Write the equation of a line, in SLOPE INTERCEPT FORM, that is perpendicular to the given equation and passes through the given
adoni [48]

Step-by-step explanation:

slope interception formula is

y-y1=m(x-x1)

where m is m=y-y1/x-x1 in this case m=-2 because the line we are trying to find is parallel to the given one y=-2x-6 where slope k=-2

so the final equation would be

y-1=-2(x-(-4))

y-1=-2x-2*4

y=-2x-8+1=-2x-7

Iteru [2.4K]

Answer:

36 ft

Step-by-step explanation:

<u>Given </u><u>:</u><u> </u>

  • 12 yards.

We need to convert it into feets. We know that ,

\implies 1 yard = 3 feet

\implies 12 yards = 12 * 3 ft

\implies 12 yards = 36 ft .

<u>Hence </u><u>the</u><u> </u><u>required</u><u> answer</u><u> is</u><u> </u><u>36</u><u> </u><u>feets </u><u>.</u>
