Answer:
X
Step-by-step explanation:
To be a function, the line has to pass the vertical line test. This means that when a vertical line is passed through every x value, it will only cross the graphed line once.
To help: draw vertical lines through each graph.
In graph W: the line would pass through the top and bottom of the circle - not a function
In graph X: the line passes once through every area - a function
In graph Y: the line passes through the top curve as well as the bottom curve - not a function
In graph Z: the line passes through the curves multiple times - not a function
Answer:
1) Plane shape
2) Solid shape
3)
4) Perimeter
5) Aerial view
6) Shadow
7) Mensuration
8) Water
Step-by-step explanation:
X + 3x = 12
(Or 4x=12)
the first x is the number of girls then the second x is the girls times 3, which is how many boys there are.
Answer:
6.3feet
Step-by-step explanation:
Given data
Radius= 4feet
The expression for the circumference of a circle is
C= 2πr
Substitute
C=2*3.142*4
C=25.136 feet
Also, a 90° arc is 1/4 of the circumference of a circle
Hence the length of the 90° arc is
=25.136/4
=6.284 feet
=6.3feet
