The equation of line AB is (y-3)= 5(x-4). What is the slope of a line perpendicular to line AB?

1 answer:

4 0

*Hint: When the slope of a line is perpendicular, it would have the negative reciprocal.

First, let's simplify this equation into y = mx + b format.

y - 3 = 5(x - 4)
y - 3 = 5x - 20
y = 5x - 17

Since 5 is the slope of this equation, the negative reciprocal would be -1/5.

Answer: -1/5

Work out the volume of the prism (answer in 1 decimal place)

Artyom0805 [142]

Answer:

Volume of the Prism = $204 cm^3$

Step-by-step explanation:

Volume of the right triangular prism= $\frac{1}{2}*Length*Width*Height$

Length=8.5 cm

Width= 6 cm

Height= 8 cm

Putting the values in the formula:

Volume of the prism :

$\frac{1}{2}*8.5*6*8\\\\=\frac{1}{2}*8.5*48\\\\ =\frac{1}{2} *408\\\\=204cm^3$

The volume of the Prism is $204 cm^3$
