The equation that best models this situation would be: y=40+30x
Step #1: Find the slope.
Slope is "rise over run" and see the attached graph to see
the rise = 1
the run = 4
and this gives a slope of 1/4.
Step 2: Find the y-intercept.
The y-intercept is where this graph hits the vertical axis. That happens at a height of 20, so your y-intercept is (0,20) and your b-value for the slope-intercept form is 20.
Step 3: Put it all together:
y = mx + b becomes
Answer: A
Step-by-step explanation:
The total area would have to be 1, so (1/2)(5)(height)=1
2.5height = 1
height = 1/2.5 = 2/10 = 1/5
Answer:
289
Step-by-step explanation:
Base of the square pyramid is square
Formula: Length × Width
17 × 17 = 289
