Answer:
f(x) = x² - 2x - 15
Step-by-step explanation:
∵ The function intersect x-axis at -3 and 5
∴ f(x) = 0 at x = -3 , 5
∵ The form of the quadratic equation is ⇒ ax² + -b/a x + c/a = 0
ax² - b/a x + c/a = 0
Where the sum of its roots is b/a and their multiplication is c/a
∵ a = 1
∵ -3 , 5 are the roots of the quadratic equation
∴ b = -3 + 5 = 2
∴ c = -3 × 5 = -15
∴ f(x) = x² - 2x - 15
Answer:
8008
Step-by-step explanation:
This is the selection of 6 elements out of 16 elements. Applying the combination formula, the total number of selections is nCr with n =16 and r =6.
16C6 = 8008
A) Ms.Wright receive $12 as interest at the end of 1/2 year.
B) Ms.Wright receive $24 as interest at the end of 1 year.
Step-by-step explanation:
The sum deposited in the bank = Principle = $800
The rate of simple interest = 3%
The time = 6 months = (6/12) years = 0.5 years

So, here simple interest = $12.
So Ms.Wright receive $12 as interest at the end of 1/2 year.
B) Now here Time = 1 year
so, Simple interest = 
So Ms.Wright receive $24 as interest at the end of 1 year.
