Answer:

a) 4³ = 4×4×4 = 64

so answer is 4³

b) (3²)⁶ = 3²×⁶

= 3¹²

so answer is 3¹²

c) 125 = 5³

(5⁴)⁷ = 5²⁸

= 5³ × 5²⁸

= 5³¹

Answer:

a, 4 the power of 3

b,3 the power of 12

c, 5 the power of 31

Step-by-step explanation:

a. prime factorization of 64 is 4^3

b. 2.6=12 so  it became 3^12

c. prime factorization of 125 is 5^3 then 7.4 =28

so 5^3 . 5^28 = 5^31

Answer:  6(6m - 1)

Step-by-step explanation:

6 - 4(3 - 6m) + 12m

= 6 -12 + 24m + 12m

= 36m - 6

= 6(6m - 1)

Answer:56

Step-by-step explanation:

The measure for m (AB) is 128 degree.

An "arc" in mathematics is a straight line that connects two endpoints. An arc is typically one of a circle's parts. In essence, it is a portion of a circle's circumference.

A curve contains an arc. A circle is the most common example of an arc, yet it can also be a section of other curved shapes like an ellipse.

We have,

The top of the easel forms a 30° angle and m (BC) = 22°.

As per the question,

AD = ED  and m<O = 30

So, m <OAE = m <OEA

                    = 1/2 (180 - m<D)

                    = 75

and, m <BEC = 1/2 (m BC)

                      = 1/2(22)

                      = 11

Then, m<BEA = m <OEA - m <BEC

                       = 75 - 11 = 64

Also, m (AB) = 2 x 64 = 128

Answer:

125.7 square inches long

Answer:

i don't know

Step-by-step explanation:

Answer:

Total height lowered = 75m

No of times balloon lowered = 5

Height lowered in each lowering = Total height lowered / No of times balloon lowered

                                                      = 75 / 5

                                                     = 15 m

The number indicated that each time balloon is lowered by 15 m

Answer:

875 Watts

Step-by-step explanation:

Given that :

P α s²

P = ks²

Where k is the proportionality constant

When ; p = 1260 ; s = 30

1260 = k * 30²

1260 = 900k

k = 1260 / 900

k = 1.4

Value of p ; when s = 25

P = 1.4 * s²

P = 1.4 * 25²

P = 1.4 * 625

P = 875 watt

Answer:

rate: 24:2

unit rate: 12:1

Step-by-step explanation:

Given function:

What is the rate?:

24 inches would be the first digit and 2 feet would be the second one..

the rate would be 24:2..

What is the unit rate?:

unit rates would be the lowest form which means that you have to find a equivalent factor to find the unit rate..

24*2=12, 2*2=1

this also means 12:1

Therefore, the rate of 24 inches and 2 feet is 24:2 and the unit rate would be 12:1.

Step-by-step explanation:

step 1: Evaluate the expressions

6*10^7 = 60,000,000
