Here's a really cool website that let's you input 3D points!

From the attached picture you can see that the point has moved back 5 units, to the left 5 units, and up 5 units.

Answer:

Option B is right

Step-by-step explanation:

In 3 dimension we have 8 octants, with x,y, z axes mutually perpendicular.

Given coordinate is (-5,-5,5)

Since x is negative we find move 5 units back first,

y is also negative hence move 5 units left

Z is positive this implies 5 units up

In two dimension we do as follows:

Locate x on the x-axis.

From that point, moving parallel to the y-axis, move y units. This is your point.

IN three dimension we extend as follows:

Locate x on the x-axis.

From that point, moving parallel to the y-axis, move y units.

From that point, moving parallel to the z-axis, move z units. This is your point

Let f (x) = 2x - 1, g(x) = 3x, and h(x) = x2 + 1. Compute the following: h (h(x)) and. g (h (x))

ki77a [65]

H(h(x)) means to use the entire function h(x) as the x value in the function h(x)..

h(h(x)) = (x²+1)² + 1
= (x²+1)(x²+1) + 1
= (x^4 + x² + x² + 1) + 1
= x^4 + 2x² + 2

g(h(x)) means to use the entire function h(x) as the x value in the function g(x)..

g(h(x)) = 3(x² + 1)
= 3x² + 3
g(h(x))

Which of the following inequalities matches the graph? (1 point)

Aleksandr [31]

Answer: 2x + y < 7

Step-by-step explanation:

In the graph we can see that:

The line is a dashed line, and the shaded area is below the dashed line, then we will have something like:

y < a*x + b

We also can see that the slope of the line is negative, and that the y-intercept is +7

Then the inequality will be something like:

y < a*x + 7

Now we can see that the line passes through the points (0, 7) and (3, 1)

Then the slope will be:

a = (1 - 7)/(3 - 0) = -6/3 = -2

that is negative, as we already said.

Then we have:

y < -2*x + 7

we can rewrite this as:

2x + y < 7

This is the first solution shown.

In 2015 Michael purchased a stock for $45.80 a share. During the year he received $1.71 per share in cash dividends. At the end

timama [110]

Michael's initial investment is $45.80, the cost of the share.
Michael Receives $1.71 in dividends.
He receives $47.50 for the stock when he sells it.
His profit on the sale of the stock is $47.50 - 45.80 = $1.70.
His total return on the stock is his total earnings, the dividends plus his profits on the sale of the stock, divided on what he paid initially, $45.80:
(1.71 + 1.70) ÷ 45.80 = .0744 = 7.45%
7.45% return on investment in less than a year, not bad!
Closest answer is 7.7%, not sure why it isn't exactly 7.45 or 7.5%.

Answer is B) 7.7%
