Answer:
i think its B
Step-by-step explanation:
a minimum requires the vertex to like be below the rest of the graph if that makes sense
a maximum means the graph doesnt exceed a point
hope this is right and helps :)
The <em>correct answer</em> is:
To draw arcs of a given size.
Explanation:
A compass is a tool used to draw a circle. Since an arc is a part of a circle, the most direct use of a compass would be to draw arcs of a given size.
To find the surface area of a prism, we must find the area of each side and add them up.
Let's first find the area of the triangular base.
The area of a triangle is

Where b is the base length and h is the height.
The base length of the triangle is 10.5. The height is 10.

The triangular base has an area of 52.5 cm².
The triangular top must also have the same area. Thus, it also has an area of 52.5 cm².
Now we to find the length of the 3 rectangles on the side of the prism.
The formula for the area of a rectangle is

where

is the width and

is the length.
All rectangles have a width of 8. They all have different lengths. If we find the area of all the rectangles, we have the following:



Now, add up ALL the areas we found. We'll have our surface area once we do this.

The surface area is 385 cm². Hope this helps! :)
Answer:
x = -76 , y = 57
Step-by-step explanation:
5x - 6y = -38
3x + 4y = 0
------------------
use 4 to multiply equation 1
5x(4) - 6y(4) = - 38(4)
20x -24y = -152
----------------------
use 6 to multiply equation 2
3x(6) + 4y(6) = 0(6)
18x + 24y = 0
------------------------
20x - 24y = -152
18x + 24y = 0
----------------------
2x = -152
----------------
divide 2 by both sides
x = -76
--------------------
to find y, slot in the of x to either equation 1 or 2
--------------------------------
equation 2
3x + 4y = 0
3(-76) + 4y = 0
------------------------
-228 + 4y = 0
4y = 228 - 0
4y = 228
---------------------
divide both sides by 4
----------------------------------
y = 57
