Answer:

6

Step-by-step explanation:

The ratio of 3 to ? must be equivalent to the ratio of 4 to 8. Since 4 to 8 is a multiple of 2, 3 to ? must also be a multiple of 2. Here it is broken down:

4*2=8

3*2=6, therefore ?=6.

Write the sum using summation notation, assuming the suggested pattern continues. 5 - 15 + 45 - 135 + ...
nalin [4]

Answer:

<em>summation of five times negative three to the power of n from n equals zero to infinity</em>

Step-by-step explanation:

<u>Summation Notation </u>

It represents the sum of a finite or infinite number of terms. Let's analyze the terms of the given succession:

5-15+45-135+...

If we take 5 as a common factor, we have

5(1-3+9-27+...)

The parentheses contain the alternate sum/subtraction of powers of 3. The odd terms are positive, the even terms are negative, thus the exponent must be n starting from 0 or n-1 starting from 1

The summation is then represented by

\sum_{n=0}^{\infty}5(-3)^n

This corresponds with the option:

<u>summation of five times negative three to the power of n from n equals zero to infinity</u>

What are the coordinates of the vertex for f(x) = x2 + 4x + 10?
MAVERICK [17]
You have to complete the square to get it into vertex form.  Do this by setting the function equal to zero and at the same time moving the constant over to the other side of the equals sign so you have this: x^{2} +4x=-10.  Now we can complete the square on the polynomial by taking half the linear term, squaring it, and adding it to both sides.  Our linear term is 4. Half of 4 is 2, and 2 squared is 4, so we add 4 to both sides: ( x^{2} +4x+4)=-10+4 and simplify to get ( x^{2} +4x+4)=-6.  In this process we have created a perfect square binomial on the left, which happens to be (x+2) ^{2}=-6.  Now move the -6 back over by addition to get (x+2) ^{2} +6=y.  The vertex is found at (-2, 6), the third choice down.
