= -(9)
= <em><u>-9 (Ans)</u></em>
Answer:
a looks congruent to 95° so it's maybe around 95°
Step-by-step explanation:
i'm not sure sorry, but i think it's close to 95°
The equation of the vertical line is 
Explanation:
It is given that the vertical line passes through the points 
For vertical line, the slope is undefined.
Hence, 
Let us substitute the coordinate
in the equation
, we have,

Simplifying, we have,


where
and 
Substituting the values of a, b and c in the equation
, we have,

Thus, the equation of the vertical line is 
Answer:
y = -3x + 9
Step-by-step explanation:
y = mx + b where m is the slope and b is the y intercept
The hypotenuse is on the same line as BC but twice as long. So extend that line up and it will cross the y axis at (0,9). 9 will be your y intercept.
To find the slope start at C and count up 9 and to the left 3 to get to B.
So the slope is rise/run or 9/(-3) = -3.
Final equation would be y = -3x + 9
Volume of men's basketball
V = 4/3 pi r^2
V = 523.6
Volume of women's basketball
V = 4/3 pi r^2
V = 381.7
Difference = 523.6 - 381.6
= 141.9 in^3
