Looking at the figure, the rectangle has the vertexes (2,1), (3,-3), (-5,-5) and (-6,-1). The parallelogram has the vertexes (2,7), (3,3), (3,-3), and (2,1).

The area of a parallelogram is base times height. We have 2 vertical lines at x=2 and x=3, so the height is 1. And the length of the line from (3,3) to (3,-3) is 6, so the base is 6. Therefore the area of the parallelogram is 1*6 = 6.

The rectangle is a tad trickier since it's not aligned with either the x or y axis. But we can use the Pythagorean theorem to get the lengths.

L = sqrt((2 - -6)^2 + (1 - -1)^2)

L = sqrt(8^2 + 2^2)

L = sqrt(64 + 4)

L = sqrt(68) = 2*sqrt(17)

W = sqrt((2-3)^2 + (1- -3)^2)

W = sqrt((-1)^2 + 4^2)

W = sqrt(1 + 16)

W = sqrt(17)

And the area is length * width, so:

2*sqrt(17)*sqrt(17) = 2 * 17 = 34

And the total area is the sum of the areas, so

34 + 6 = 40

So the area of the figure is 40 square units.

Write a rule for a geometric sequence that has -6 as its first term and a common ratio of 2. What is the tenth term of this sequ

slega [8]

The general form of the geometric sequence is $a_{n} = a_{1} (r) ^{n-1}$ , where a sub n is the number term you're looking for (we're looking for the tenth term). a sub 1 is the first term in the sequence (ours is -6), r is the common ratio, and n-1 is the numbered term you're looking for minus 1. Our formula then looks like this: $a_{10} =-6(2) ^{10-1}$ . Simplify it to $a_{10} =-6(2)^9$ . Take 2 to the 9th power then multiply it by -6 to get -3072. C is your answer.

1 When the product of 4 and a number x is added to 12, the result is 16. What is the difference between x and 8?

Aleks [24]

Answer:

x = 1

Step-by-step explanation:

12 + 4 x = 16

Subtract 12 from both sides.

4x = 4

Divide 4 on both sides.

x = 1
