Formula of the sum of the 1st nth term in a Geometric Progression:
Sum = a₁(1-rⁿ)/(1-r), where a₁ = 1st term, r = common ratio and n= rank nth of term (r≠1)
Sum = (-11)[1-(-5⁸)] /[(1-(-5)]
Sum = (-11)(1- 390625)/(6)
SUM = 716,144
Answer:
a = - 4, b = 5
Step-by-step explanation:
Expand the left side, then compare the coefficients of like terms.
- 3(2x² + ax + b)
= - 6x² - 3ax - 3b, compare to - 6x² + 12x - 15
Compare coefficients of x- terms
- 3a = 12 ( divide both sides by - 3 )
a = - 4
Compare constant terms
- 3b = - 15 ( divide both sides by - 3 )
b = 5
Answer:
35/8
Step-by-step explanation:
4×8= 32 plus the 3/8 equals 35/8

I'm assuming you are referring to the radius of a square
The first thing we have to do is divide by pi, because it's the last thing you do when calculating the area.
2289.06/3.14
729
Now, we have to take the square root of this number because the radius in the area formula is squared.
729^1/2
27
So, the radius is 27.
I think it is A but I'm not really sure
