Percent increase = (new number - original number) / original number...* 100
= (42 - 20) / 20....* 100
= 22/20 * 100
= 1.1 * 100
= 110 % increase
Answer:
Rate of Change/Slope = -20
Equation: y= -20x +100
Step-by-step explanation:
A. We know the rate of change is also known as the slope. If we used the slope formula to find the slope we can find the Rate of Change.
B. Since we know the slope and 1 point on the graph we can substitute them in for 'b'
(0,100)
(100)=-20(0) + b
b = 100
Since we know the slope and the b value we can write the equation:\
y = -20x +100
Area of a rectangle: Length x Width
Areas of the rectangular container : 20cm x 16cm , which is 320cm^2
If the rock caused the container to rise 1.5cm, then the volume of the rock will be 1.5cm x the area of the container:
320cm^2 x 1.5cm = 480cm^3
Answer: 480cm^3
Answer:
Option 2
Step-by-step explanation:
There is an amplitude of 1/2, a period of pi, and a non-zero y-intercept.
