Answer:
Step-by-step explanation:
V^-1(h)is find inverse function=h / 12π
V=12πh=420π
h=420π/12π=35 feet
Answer:
40
Step-by-step explanation:
The median is the middle line of the box, which is the value 40. The lower quartile would be 35 and the upper quartile being 50.
The equation of a line in point-slope form is expressed as:
y = mx + b
- m is the slope of the line
Given the inequality -2y > 7x + 4, this can also be expressed as:
-2y > 7x + 4
y < -7/2x -4/2
y< -7/2x - 2
This shows that the line will be a dashed line and cuts the y-axis at y= -2

Answer:
a. the investment earns 4%
b. yes
Step-by-step explanation:
The "rule of 72" says that an investment earning compound interest at x% will double in value after 72/x years. That is, ...
f(x) = 72/x
__
<h3>a.</h3>
We interpret f(4) to mean Becky's friend is interested in the doubling time for an investment that earns 4% interest.
__
<h3>b.</h3>
Using the above formula, ...
f(4) = 72/4 = 18
The friend's math is correct.
