300% in decimal form is 3
Answer:
First you need to state the equation that represents the function.
Investment is $200 and interest rate is 5%, y is the amount of money after x periods.
Note that after 1 period the amount of money is 200 plus 5% interest, which is 200 + 5%(200) = 200 (1 +5%) = 200 (1 + 0.05) = 200 (1.05)
After 2 periods the amount is 200(1.05)*(1.05) = 200 (1.05)^2
After 3 periods the amount is 200 (1.05)^3
And now you can deduce that after x periods y = 200 (1.05)^x
You can then analyze the function to predict the shape and critical points of the graph.
The answers are based in the initial value and the increasing factor.
The initial value is when x = 0, which yields to y = 200 (1.05)^0 = 200*1 = 200
And the increasing factor is 1.05 because any value is the previos one times 1.05.
Step-by-step explanation:
Answer:
9x^2 - 6x + 1.
Step-by-step explanation:
(6x^2-x+8) - (5x-3x^2+7) Distribute the negative over second brackets:
= 6x^2 - x + 8 - 5x + 3x^2 - 7
= 9x^2 - 6x + 1.
For this case we need the following skills:
Adding fractions // Subtracting fractions: necessary because operations with fractions need algebraic sum to clear unknowns.
Multiply fractions / Dividing fractions: Sometimes when doing common factor, you need to multiply and divide fractions.
Simplifying fractions: To rewrite the results, it is necessary to simplify fractions
Answer:
All mentioned skills are required.
