Answer:
Compound interest is the best.
Step-by-step explanation:
Simple interest is that which is not added to the initial capital once the term of the investment or credit has expired.
Compound interest is that which is added to the initial capital at the end of the investment or credit.
Simple interest:
I= C x i x t
15,000 * 0.05 * 5 = $ 750
Compound interest:
Cf= Ci (1+i)ᵗ
Cf = 15,000 * (1.039)^5 = $ 18,162.22
So, if Cf - Ci = I -> 3,162.22 is the compound interest.
Given a quadratic function
y = 4x² - 19x - 5
or i will write it as
4x² - 19x - 5 = y
Zero of the function is when y have the value of zero.
So the quadratic equation will be
4x² - 19x - 5 = y
4x² - 19x - 5 = 0
Now make the equation to intercept form by factorization
4x² - 19x - 5 = 0
(4x + 1)(x - 5) = 0 (this is intercept form)
Solution 1
4x + 1 = 0
4x = -1
x = -1/4
Solution 2
x - 5 = 0
x = 5
SUMMARY
-1/4 and 5 are zero function of f(x) = 4x² - 19x - 5
x = 3g + 2
- 2 - 2
x - 2 = 3g
÷ 3 ÷ 3
x - 2 ÷ 3 = g
Answer:
16
Step-by-step explanation:
x = number of footballs he can order
22*x + 13 (shipping fee) = 277
22x = 264 Subtract 13 from both sides
x = 16 Divide both sides by 22
Our solution is 16 footballs
