Answer:

Step-by-step explanation:

1. slope=-3/2-3 is at the top,2 is at the bottom

y intercept=4-The y intercepts or goes past at 4,

equation=y=-3/2+4-We put it all together and we get y=-3/2+4!

2. slope=-3/2-It starts at 3 again,and ends at two again.

y intercept=0-The y touches the line at 0,or the middle

equation=y=-3/2-y equals the slope and we subtract y.

The diagram below shows scalene triangle JKL. Triangle J K L. Side L K extends to point H to form exterior angle J K H. Which is

DiKsa [7]

Answer:

Step-by-step explanation:

Measure of angle J K H + measure of angle J K L = 180 degrees

True.

Measure of angle J K L + measure of angle J L K + measure of angle K J L = 180 degrees

True. The sum of all interior angles = 180

Measure of angle J K H = measure of angle J L K =

Find and sketch the domain of the function. f(x,y)=√(4-x^2-y^2) +√(1-x^2)<br>

elena55 [62]

Answer:

Hello

Step-by-step explanation:

The domain is limited with 2 lines parallel: -1 ≤ x ≤ 1

and the disk ? (inside of a circle) of center (0,0) and radius 2

$dom\ f(x,y)=\{(x,y) \in \mathbb{R} ^2 | \ -1\leq x \leq -1\ and \ ( -\sqrt{4-x^2} \leq \ y \leq \sqrt{4-x^2}\ ) \ \}\\$

Plz help with this math. Can't find the area of the triangular faces.

Zina [86]

First of all, you have to find the area of both triangles:
$\frac{bh}{2}$
$\frac{4*4}{2}$
Or just 16 because there are 2 of the same triangles.

Now you have to find the area of the 3 rectangles.

The two that are in the front are 4*3 (l*h) or 12*2 (because there are 2 congruent rectangles. The area of those rectangles is 24 square mm.

Now you find the area of the back rectangle:
5.7*3 = 17.1

Finally, you add all the found numbers to figure out the surface area.
17.1 + 16 + 24 = 57.1 square millimeters.

Hope this helped,

Esther has a farm.

Gnesinka [82]

Here, we are required bro determine how many worker Esther needs to employ to pick the same 600kg of onions in 3 hours as compared to 4 hours from last year.

This year, she needs to employ 32 workers to pick a total of 600kg of onions in 3 hours.

According to the data given, the total quantity of onions to be picked still remains 600 kg as from last year, only that she needs it done in 3 hours now.

Therefore,

Since 24 workers finished the work in 4 hours,
This means that 96 workers are needed to finish the work in 1 hour( from 24×4 = 96).

Therefore, since the work needs to be done in 3 hours this year, This means that it can be shared between X no. of workers.

Where X = 96/3= 32

Therefore, this year she needs to employ 32 workers to pick a total of 600kg of onions in 3 hours.
