Answer:
the answer depends on which type of interest we use:
- simple interest rate = 24%
- compound interest rate = 26.82%
Step-by-step explanation:
the interest rate paid for holding the cards one month 1/50 or 2%.
to convert 2% monthly interest rate to a simple annual rate:
monthly rate x 12 months = 2% x 12 = 24%
now to convert 2% monthly interest rate to an annual rate (using compound interest):
- = (1 + r)ⁿ - 1
- = (1 + 0.02)¹² - 1 = 1.2682 - 1 = 0.2682 or 26.82%
in compound interest, earned interest earns even more interest by itself besides the interest earned by the principal.
To find the gradient of a line you use this equation: Rise / Run
I am assuming this is a graph where both the x and y-axis increase in value by one.
So first of all, you should draw out this graph.
Second, draw a point at each of the given coordinates.
Now, join these points by drawing a right angle triangle. Put simply, draw a line from the point (4, -7) down until it is on the same level as the point (2, -3), then draw a line across.
Finally, measure the length of both these sides and use them in the equation above.
Let's assume the rise (vertical line) and the run (horizontal line) are 5 and 8 respectively. We can do 5/8 to get a gradient which is 0.625.
Answer:
w= -27
Step-by-step explanation:
w/3 = -9
w = 3 * -9 = -27
The unit price is $1.23 (I think!!)
We are given y = kxz
We also know 32 = k×6×8, so k = 32/48 = 2/3.
We are then asked to solve:
