Step-by-step explanation:
When you multiply exponents of the same base (variable), add the exponents.
1. The exponents are 12 - 4 + 6 = 14 or c^14
When you divide exponents of the same base, subtract them.
2. 8 - 2 = 6 or c^6
When you raise a power to a power, you multiply the exponents.
3. 4 * 5 = 20 or c^20
When a number is raised to a negative exponent it can be re written like this x^-n = 1/x^n.
4. x^-2 * y / x^4 * y^-1; using the above information, rewrite everything to have positive exponents. If the negative exponent is in the denominator, then it becomes x^n/1
y * y / x^2 * x^4 ; then just add your exponents to simplify
y^2 / x^6
As we said before, a power raised to a power is exponent x exponent.
5. (a^2 * b) ^-1 / (a^-3 * b^2)^-1 ; as before a power raised to a power, multiply the powers.
a^-2 * b-1 / a^3 * b^-2 rewrite this as before, inverting negative exponents. a^3 / a^2 * b^1 * b^2 = a^3 / a^2 * b^3
Simolifynthe new expression to reduce the a variable by subtracting the bottom a^2 from the top a^3 and are left with
a / b^3
Work number 6 like 5, no negative exponents, so there won't be any inversions. Just multiply the outside power times every exponent, then do the division by subtracting exponents of like bases.
When figuring out the problems with constants, treat them like the variables. In number 7 the 5a^2 when raised to the 2nd power would be 5^2*(a^2)^2 = 25 a^4

Answers
Answer:
Step-by-step explanation:
First you have to calculate CB in order to use sin law to calculate ∠A
CB=[tex]\sqrt{18.4^{2} -13.2^{2} }[/tex]
CB=12.8(correct to nearest tenth)
After that, use sin law to calculate ∠A,
[tex]\frac{18.4}{sin90} =\frac{12.8}{sinA}[/tex] or [tex]\frac{sin90}{18.4} =\frac{sinA}{12.8}[/tex]
sinA=0.695...
A=44.079...
=44.1(corrext to the nearest tenth)
Is that clear enough for you?

Let’s use a random equation
(3x-7)(6x+2)
the F stands for “first”... the 3x is first in its parenthesis. The 6x is the first in its parenthesis. So multiply those. You get 18x^2
The O stand for “outer” the 3x and 2 are the outer. They equal 6x.
the I stand for “inner”. -7 and 6x are the inner parts of the equation. They equal -42x
The L stand for last. The last are -7 and 2. They equal-14.
Put it all together
18x^2+6x-42x-14
18x^2-36x-14

The populations and land areas of four cities in Texas are shown. Which statements are true? Check all that apply. The population density for City B can be found using the ratio 48,592 : 26. The population density for City D can be found using the ratio 258 : 196,429. City A has the greatest population density of the four cities. The population density of City B is greater than that of City C. City D has the lowest population density of the four cities.
Answers
Answer:
The population density for city b would be 48,592 ÷ 26
The population density for city b is more than the city c
And, the city d contains the lowest population density
Step-by-step explanation:
The computation is given below:
As we know that
Population density = Population ÷ Area
So
For city A = 2,195,914 ÷ 1,553 = 1413.98
For city B = 48,592 ÷ 26 = 1868.15
For city C = 1,257,676 ÷ 999 = 1258.93.
For city D = 196,429 ÷ 258 = 761.35.
The following are the true statements:
The population density for city b would be 48,592 ÷ 26
The population density for city b is more than the city c
And, the city d contains the lowest population density

Answer: 3/2 cm per second
========================================================
Explanation:
We could compute the slope of this line to get the answer, or we could simply compute y/x. This shortcut only works because the line goes through the origin. If the line didn't go through the origin, then we would have to use the slope formula.
The unit rate is y/x = 9/6 = 3/2 cm per second. I used the point (9,6) to compute the unit rate.
We can think of the fraction 3/2 as 1.5, so the unit rate is equivalent to 1.5 cm/sec.
