Why does a horizontal line have a slope of zero, but a vertical line have an undefined slope?
shusha [124]
Refer to the diagram shown below.
Define two positions on each line as A (x₁, y₁) and B(x₂, y₂).
Then the slope is
m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Horizontal line:
Define A (0, 1) and B (1,1).
The slope is
m= \frac{1-1}{1-0}=0

Vertical line:
Define A( (1,0) and B(1,1).
The slope is
m= \frac{1-0}{1-1}= \frac{1}{0}  (undefined)

A manufacturing plant earned \$80$80dollar sign, 80 per man-hour of labor when it opened. Each year, the plant earns an addition
vagabundo [1.1K]

Answer:

A(t)=80(1.05)^t

Step-by-step explanation:

The manufacturing plant earned $80 per man-hour of labor when it opened

The plant earns an additional 5% for every additional man-hour t.

This can be modeled using the function:

A(t)=P(1+r)^t

where Initial Amount Earned, P=80

Rate of Increase, r=5%=0.05

Therefore, the function that models the amount earned at any time t is:

A(t)=80(1+0.05)^t\\A(t)=80(1.05)^t
