Calculate 8 ∙ 10-4 divided by 2 ∙ 102. (box after the "10" in answer is for the exponent.). ∙ 10
Korolek [52]

Given problem: \frac{8*10^{-4}}{2*10^2}.

Solution: We can see that first we have 8 and 2 numbers in front of 10's powers.

So, we need to simplify 8 over 2 first.

If we divide 8 by 2, we get 4.

Now, let us work on 10's and their powers.

10^{-4} is being divided by 10^{2}.

We can apply quotient rule of exponents remaining part.

According to quotient rule of exponents, \frac{a^m}{a^n}=a^{m-n}

If we apply same rule, we need to subtract exponents of 10's.

\frac{10^{-4}}{10^2}=10^{-4-(-2)}

If we simplify exponent part -4-(-2), it will give us -4+2 =-2.

So, 10^{-4-(-2)}=10^{-2}

And final answer would be 4 \times 10^{-2}.

Find angles A, B, C, D, & E.
matrenka [14]

Answer:

Step-by-step explanation:

B = 35      {Alternate interior angles}

C = 75      {Corresponding angles}

D + 75 =  180 {Linear pair}

     D = 180 - 75

     D = 105

A = C   {Corresponding angles}

A = 75

E = A   {Alternate interior angles}

E = 75

Y = mx + b is the slope-intercept form of the equation of a line,
where m = slope, and b = y-intercept.

In problems 1 and 3, your equations are written in the y= mx + b form, so you can read the slope and y-intercept directly.

1.
m = -5/2
b = -5

3.
m = -1
b = 3

5.
For problem 5, you need to solve for y to put the equation
in y = mx + b form. Then you can read m and b just like we did
for problems 1 and 3.

4x + 16y = 8

16y = -4x + 8

y = -4/16 x - 8/16

y = -1/4 x - 1/2

m = -1/4

b = -1/2

Answer:

Domain

Step-by-step explanation:

There isn't really a detailed explanation I could personally give you. In Algebra we learned that your domain were your x values (input), and your y values were your range (output).
