Write the midpoint of the segment as an order pair.

Svetllana [295]

Answer:

1. (3, 5)

2. (1/2, 4)

Step-by-step explanation:

To find the coordinates of the midpoint of a segment, find the average of the x-coordinates of the endpoints and the average of the y-coordinates of the endpoints.

1. (1, 2) and (5, 8)

x-coordinate of midpoint = (1 + 5)/2 = 6/2 = 3

y-coordinate of midpoint = (2 + 8)/2 = 10/2 = 5

Midpoint: (3, 5)

2. (0, 1) and (1, 7)

x-coordinate of midpoint = (0 + 1)/2 = 1/2

y-coordinate of midpoint = (1 + 7)/2 = 8/2 = 4

Midpoint: (1/2, 4)

How do i solve for x? *you have to show work*

eduard

1) Factor the equation first:

$2e^{2x} + 4xe^{2x} = 0$
$e^{2x}(2 + 4x) = 0$

So either $e^{2x} = 0$ or $2 + 4x = 0$ . But $e^{2x} = 0$ can never equal 0! So, we only need to solve for the second equation:

$2 + 4x = 0$
$\bf x = {-\frac{1}{2}}$

2) First, single out the term with the exponent:

$2 + 3(4^{2x - 1}) = 43$
$3(4^{2x - 1}) = 41$
$4^{2x - 1} = \frac{41}{3}$

Now, taking the log base 4 of each side gives us

$2x - 1 = \log_4 \frac{41}{3}$

and we can now solve for x:

$2x - 1 = \log_4 \frac{41}{3}$
$2x = 1 + \log_4 \frac{41}{3}$
$2x = \log_4 4 + \log_4 \frac{41}{3}$
$2x = \log_4 \frac{164}{3}$
$x = \frac{1}{2} \log_4 \frac{164}{3}$
$x = \log_4 \sqrt \frac{164}{3}$
$\bf x = \log_4 2 \sqrt \frac{41}{3}$

What is 4x squared times 4x squared? Is it 16x to the fourth power?

Luda [366]

4x² * 4x² = We can change the order of the factors
4 * 4 * x² * x² = 16 * x²⁺² = 16*x⁴ = 16x⁴
