Mathematics
1 answer:
Jobisdone [24]3 years ago
3 0
A unit rate can be represented as"The number of x's per 1." They are often given in scenarios of several days, and you need to calculate what happened in 1 day.

For example:
John sells 60 watermelons in 30 day. What is the unit rate of his sells?

If he sells 60 in 30 days, that means he sells 2 watermelons per day. Therefore, the unit rate is 2.

The Choi family wants to save money to travel the world. They purchase an annuity with a monthly payment of $65 that earns 4.5%
Lesechka [4]

Answer:

You can get an idea of how much guaranteed lifetime income a given amount of savings will buy by going to this annuity payment calculator. Today, for example, $100,000 would get a 65-year-old man about $525 a month in lifetime income, while that amount would generate roughly $490 a month for a 65-year-old woman.

Determine the graph of the polar equation r=4/(1-1/2cosx(theta))
crimeas [40]

Answer:

  see below

Step-by-step explanation:

We assume you want the graph of ...

  r=\dfrac{4}{1-\frac{1}{2}\cos{(\theta)}}

A graphing calculator or spreadsheet is useful for this.

__

You know cos(θ) = cos(-θ), so the graph is symmetrical about the x-axis. You can evaluate the function at a few points to find the general outline.

  r at 0° = 8

  r at 30° ≈ 7.05

  r at 45° ≈ 6.19

  r at 60° ≈ 5.33

  r at 90° = 4

  r at 120° = 3.2

  r at 135° ≈ 2.96

  r at 150° ≈ 2.79

  r at 180° ≈ 2.67
