Answer:
3.14
Step-by-step explanation:
The formula for the area of a circle is ...
A = πr²
The constant of proportionality is the constant in this equation: π. To two decimal places, the value of π is 3.14.
The constant of proportionality is about 3.14.
Answer:
y = 4x - 11 .
Step-by-step explanation:
The line y = 4x - 9 has a slope of 4 so our line will also contain 4x.
Using the point-slope form of the equation of a line:
y - y1 = m(x - x1) , we have m = 4 and (x1, y1) = (2, -3):
y - -3 = 4(x - 2)
y + 3 = 4x - 8
y = 4x - 11 (answer).
How many piles the plates are stacked in I think
Answer:c=5h+20
Step-by-step explanation:The question says it is $20 plus 5$ per hour, $5 per hour would be equal to 5h, and 20 would be the y intercept in this equation, and using slope intercept form, youd get 20, by itself, after 5h. So the equation would be c=5h+20
