Answer:
20300m^2
Step-by-step explanation:
first try to imagine the shape bisected into a rectangle and a triangle
to find the missing part of the triangle or the bottom side you need to subtract 70m from 140 m
140m-70m=70m this will be the base of your triangle
now you need the side
230m-60m=170
triangle formula base x height/ 2
70m x 170m=a
11900m=a
now the rectangle
base x height=a
60m x140m=a
8400m=a
finally add the two quantities together
8400m+11900m=a
20300m^2=a
Slope (m) = (y2-y1)/(x2-x1) = (0-(-2))/(2-(-2)) = 2/4 = 1/2
Final answer:
M = 1/2
Answer:
Step-by-step explanation :
Step-by-step answer:
A vertical line test checks for single or multiple intersections with a given relations If there is a maximum of one intersection with the relation at ANY point in the domain of the relation, we can conclude that the relation is a function. If there are multiple intersections of a VERTICAL line with the function, it is not a function.
Here, we see that vertical line test on the relation shown does not produce more than one intersection at any point in the domain of the relation, hence we conclude that the graph shows a function.
An inverse of a function is a reflection of the function about the y=x line. The result is the same as the interchange of the x and y-axes.
Hence a horizontal line test on the inverse of a function gives the same results as a vertical line test of the function itself, and the conclusion is identical to the test given above in paragraph two.
Answer:
The height of the water is 
Step-by-step explanation:
step 1
Find the volume of the tank
The volume of the inverted right circular cone is equal to
we have
substitute
step 2
Find the 25% of the tank’s capacity
step 3
Find the height, of the water in the tank
Let
h ----> the height of the water
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional
substitute
where
r is the radius of the smaller cone of the figure
h is the height of the smaller cone of the figure
R is the radius of the circular base of tank
H is the height of the tank
we have
-----> volume of the smaller cone
substitute
Simplify
