Answer: 5 units
Step-by-step explanation:
The area of a parallelogram is . SInce we know the area and the height, we can directly plug the values into this equation and solve for the base.
20=b(4) [divide both sides by 4]
b=5 units
Y-axis, because what i’ve been taught with coordinates, is you crawl before you walk which means is first it’s x-axis then y-axis. so (0,4) would be on the y-axis. :)
Answer:
Step-by-step explanation:
y = a|x-h| + k
(h,k) is the vertex
There's no standard formula for absolute values. I just made it up as an example, pretty much.
Since a is negative, the function opens downward.
h = -2, k = 0, so the vertex is at (-2,0)
Answer:
- <u>The rate of return is 8.15%</u>
- <u>This is a good investment</u>
<u></u>
Explanation:
For the first question, you need to find the rate that makes the present value of a stream of ten constant annual payments of $15,000 equal to the $100,000 investment.
The formula that returns the present value of a constant payment is called the annuity formula and is:
In your problem you know:
- Present value: $100,000
- payment: $15,000
- r: ?
- t: 10
You cannot solve for r directly. You must guess a value and calculate the right side of the equation until to you find the rate that makes it equal to 100,000.
Try 5%:
Then, the rate of return is greater than 5%. After several trials you will find that the rate of return is 8.15%.
Since this rate is higher than 8%, which is what the company requires, this is a good investment.
