Answer:

Form: 2^7, 2^7 = 128

Step-by-step explanation:

You cannot multiply exponent, you must add the exponents.

4 + 3 = 7.

Keep the base the same.

Then find what 2^7 is.

Multiply:

2 x 2 x 2 x 2 x 2 x 2 x 2.

2 x 2 =

4 x 2 =

8 x 2 =

16 x 2 =

32 x 2 =

64 x 2 =

128.

A gas pump fills 2^-2 gallon of gasoline per second. how many gallons does the pump fill in one minute?

astraxan [27]

Answer:

The gas pump filling the gallons in 1 minute will be: 15

Step-by-step explanation:

Given that a gas pump fills 2^-2 gallon of gasoline per second.

As there are 60 seconds in 1 minute.

Thus,

Gas pump filling the gallons in 1 minute will be:

$60\:\times 2^{-2}$

$=60\times \frac{1}{2^2}$ ∵ $a^{-b}=\frac{1}{a^b}$

$\mathrm{Multiply\:fractions}:\quad \:a\times \frac{b}{c}=\frac{a\:\times \:b}{c}$

$=\frac{1\times \:60}{2^2}$

$=\frac{60}{2^2}$

$=\frac{2^2\times \:3\times \:5}{2^2}$

$=3\times \:5$

$=15$ gallons in one minute

Therefore, the gas pump filling the gallons in 1 minute will be: 15

What’s the correct answer for this?

First, you'd work out the centre value

It would be the opposite value to what is in the brackets

Thus, the centre value is (2, -4)

Plot this value on a graph

In order to find the radius, you must square root the 25

Thus, the radius would be 5

Plot some points with a radius of 5 from the centre and then draw the circle

Find the distance from point a (7/8, -1/8) to point b (-1/8, 7/8)

VashaNatasha [74]

Answer:

sqrt(2) ≈1.414213562

Step-by-step explanation:

Distance is found by the formula

d =sqrt ( (x2-x1)^2 + (y2-y1)^2)

= sqrt( (-1/8 - 7/8)^2 + (7/8 --1/8)^2)

sqrt( (-8/8)^2 + (7/8 +1/8)^2)

sqrt( (-1)^2 + (1)^2)

sqrt ( 1 +1)

sqrt(2)
