2 to the power of 3 is

2 x 2 x 2 = 8

10 to the power of 2 is

10 x 10 = 100

then add 4

104

8/104

I believe this is how you do it :) hope this helps

What is the equation of the line that is parallel to the given line and passes through the point (–2, 2)?

uysha [10]

Answer:

y = 1/5 x + 12/5

Step-by-step explanation:

We are looking for the equation of a line.

We satart with the slope-intercept form of the equation of a line.

y = mx + b

We need to find m, the slope, and b, the y-intercept.

The given line is y = 1/5 x - 3.

Its slope is 1/5.

Parallel lines have equal slopes, so the slope we need is also 1/5.

Now we have for our line

y = 1/5 x + b

Now we find b.

We are given a point on the line, (-2, 2). Using the slope we already know, plug in (-2, 2) in the equation and solve for b.

2 = 1/5 * (-2) + b

10 = -2 + 5b

12 = 5b

b = 12/5

Now that we know the y-intercept, we can write the equation of the line.

y = 1/5 x + 12/5

Round your percent to two decimal places as needed

Mrrafil [7]

Step-by-step explanation:

The ratio is 459/484.

The percent is:

459/484 × 100%

= 94.83%

The percent left is:

100% − 94.83%

= 5.17%

For the following function

andrey2020 [161]

Answer:

(a) f(4) = 11

(b) f(-1) = 211

(d) f(2/m) = (151m² -110m +20)/m²

(e) x = 5 or x = 6

Step-by-step explanation:

A graphing calculator can help with function evaluation. Sometimes numerical evaluation is easier if the function is written in Horner Form:

f(x) = (5x -55)x +151

(a) f(4) = (5·4 -55)4 +151 = -35·4 +151 = -140 +151 = 11

(b) f(-1) = (5(-1)-55)(-1) +151 = 60 +151 = 211

(c) Replace x with a:

f(a) = 5a² -55a +151

(d) Replace x with 2/m; simplify.

f(2/m) = 5(2/m)² -55(2/m) +151 = 20/m² -110m +151

Factoring out 1/m², we have ...

f(2/m) = (151m² -110m +20)/m²

(e) Solving for x when f(x) = 1, we have ...

5x² -55x +151 = 1

5x² -55x +150 = 0 . . . . subtract 1

x² -11x +30 = 0 . . . . . . . divide by 5

(x -5)(x -6) = 0 . . . . . . . . factor

Values of x that make the factors (and their product) zero are ...

x = 5, x = 6 . . . . values of x such that f(x) = 1
