(I'm learning this right now!)
y = 3x - 3
If a line is perpendicular to another line, they have negative reciprocal slopes.
So you would use the slope -1/3.
Use y - y₁ = m(x - x₁) to get an equation in slope intercept form.
Plug the numbers in.
y - 1 = -1/3(x - 3)
y - 1 = -1/3x + 1
y = -1/3x + 2
An equation of a line perpendicular to line CD is y = -1/3x + 2.
Answer:128cm^3
Step-by-step explanation:
Base area=48cm^2
Height=8cm
Volume=1/3 x base area x height
Volume=1/3 x 48 x 8
Volume=(1x48x8)/3
Volume=384/3
Volume =128cm^3
Answer:
7.834 × 10^-8
Step-by-step explanation:
= 7.834 × 10^-8
(scientific notation)
= 7.834e-8
(scientific e notation)
= 78.34 × 10^-9
(engineering notation)
(billionth; prefix nano- (n))
= 0.00000007834
(real number)
^ means the number after is exponent.
The multiplicative inverse of 1 is in fact 1/1 which is equal to 1. So 1 is actually its own multiplicative inverse.
