eeeeeAnswer:
Step-by-step explanation:
Solve your equation step-by-step.
2700=2200(1+r)^5
Flip the equation.
2200(r+1)^5 = 2700
Divide both sides by 2200.
2200(r+1)^5 / 2200 = 2700 / 2200
(r+1)^5=27/22
Solve Exponent.
(r+1)^5=27/22
((r+1)5) ^1/5 = (27/22)^1/5 (Raise both sides to power)
r+1=1.041809
r+1−1=1.041809−1(Subtract 1 from both sides)
r = 0.041809
Check answers. (Plug them in to make sure they work.)
r = 0.041809 (Works in original equation)
Answer:
4
Step-by-step explanation:
because you do 2-1 and then 3 * 3 the equation would look like this
1 + (3*3) /
1+9/ 3
1 + 3

Answer:
Therefore, equation of the line that passes through (2,2) and is parellel to the line 
is 
Step-by-step explanation:
Given:
a line
To Find:
Equation of line passing through ( 2, 2) and is parellel to the line y=7x
Solution:
...........Given
Comparing with,
Where m =slope
We get
We know that parallel lines have Equal slopes.
Therefore the slope of the required line passing through (2 , 2) will also have the slope = m = 7.
Now the equation of line in slope point form given by
Substituting the points and so we will get the required equation of the line,
Therefore, equation of the line that passes through (2,2) and is parellel to the line is
(3m+5n)(9m²-15mn+25n²)
1) Let's factorize 27m³ +125n³.
27m³ +125n³ <em>Let's use x³ +y³ product to factorize that</em>
<em />
x³ +y³ = (x +y)(x²-xy +y²)
2) So let's rewrite it, since 3³ = 27 and 5³ = 125
27m³ +125n³ =
Plug x =3m and y = 5n into those factors (x +y)(x²-xy +y²)
27m³ +125n³= (3m + 5n)(3²m² -5n*3m +5²n²)
27m³ +125n³= (3m+5n)(9m² - 15mn +25n²)
3) So the answer is
(3m+5n)(9m²-15mn+25n²)
