Answer:
the length of FC = b = 12 cm
Step-by-step explanation:
The volume of prism is given along with height and height of triangular base. WE need to find the length of base.
V= B*h
where B= area of base = 1/2 * b *h
V= ( 1/2 *b * h) * h
900= 1/2 * b * 10 * 15
900 * 2 = b* 150
1800 = b* 150
=> b= 1800/150
b= 12 cm
So the length of FC = b = 12 cm

When the X value is zero, the Y value is negative two.
Answer:
x=291/76
Step-by-step explanation:
Convert:
1/2x(6x+ 1/2)=-0.8x+16-1.2
Remove parenthesis and move terms:
3x+1/4=-0.8x+14.8
Collect the like terms and convert:
3x+0.8x=14.8-1/4
Subtract the fractions:
3.8x=74/5-1/4
Divide both sides by 3.8:
3.8x=291/20
x=291/76
