Answer: 7i
explanation: √-1 is i because a negative square root is imaginary. you can take out the negative from the inside of the square root and replace it with i on the outside. that leaves you with √49, which is 7, and that gives you 7i
3/4z - 1/4z + 3 = 2/4z + 5
3/4z - 1/4z - 2/4z = 5 - 3
2/4z - 2/4z = 2
0 ≠ 2

Answer:
17.0°
Step-by-step explanation:
We want to solve
![\tan(x) = \frac{3}{10}](https://tex.z-dn.net/?f=%20%5Ctan%28x%29%20%20%3D%20%20%5Cfrac%7B3%7D%7B10%7D%20)
We take inverse tangent of both sides using a scientific calculator to get:
![x = { \tan}^{ - 1} ( \frac{3}{10} )](https://tex.z-dn.net/?f=x%20%3D%20%20%7B%20%5Ctan%7D%5E%7B%20-%201%7D%20%28%20%5Cfrac%7B3%7D%7B10%7D%20%29)
![x = 16.6992](https://tex.z-dn.net/?f=x%20%3D%2016.6992)
We round to the nearest tenth to get;
![x = 17.0 \degree](https://tex.z-dn.net/?f=x%20%3D%2017.0%20%5Cdegree)
Therefore the value of x is 17.0°
Example :
u have an endpoint at (6,5)......ad the midpoint is (4,2)....find the other endpoint.
midpoint formula : (x1 + x2) / 2, (y1 + y2) / 2
one endpoint (6,5)....x1 = 6 and y1 = 5
other endpoint (x,y)...x2 = x and y2 = y
sub into the formula
m = (6 + x) / 2, (5 + y) / 2
okay, so the midpoint is (4,2)....so ur x value will equal 4
(6 + x) / 2 = 4...multiply both sides by 2
6 + x = 4 * 2
6 + x = 8
x = 8 - 6
x = 2 <==
midpoint is (4,2)....so the y value will equal 2
(5 + y) / 2 = 2 ...multiply both sides by 2
5 + y = 2 * 2
5 + y = 4
y = 4 - 5
y = -1 <==
so ur other endpoints are (2,-1)
I think it’s 2,000 but again I could be wrong I need like the options
