Describe why it might not be a good idea to use a key where each symbol stands for 1 in a picture graph

1 answer:

4 0

In a picture graph, if there is no key specified, then it is already assumed that the viewer knows that each symbol would stand for 1. If each symbol stands for more than one, then a key is required, but if each symbol stands for one, you can assume that the viewer knows.

A volcano in the approximate shape of a cone has a diameter of 16 km and a height of 1.95 km. Which estimate best approximates t

masha68 [24]

To find the approximate volume of the volcano, you will use the formula for finding the volume of a cone.

V = 1/3 x pi x r^2 x h
1/3 x 3.14 x 8^2 x 1.95
V = 130.624

The approximate volume of the volcano is 131 cubic kilometers.

Which systems of equations has a solution of approximately -2,7 , -1,2

Yakvenalex [24]

The point of intersection you are concerned with is the left-most of those of the graphed lines. Thus you want the two equatons that both have x-intercepts that are negative. Since the x-coefficient is positive in every case, this will mean the right-side constants of these equations both need to be negative. The appropriate choice is ...
A. 4x - 5y = -5 and 3x + 10y = -20
