Answer:

ax2 + bx + c = 0.

Step-by-step explanation:

The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero.

Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

ANSWER

The explicit formula is :

$a_n = 8+ 3(n - 1)$

EXPLANATION

The given sequence is

8,11,14,17,20,23,26,...

The first term is

$a_1=8$

The common difference is

d=11-8

d=3

The explicit formula is given by:

$a_n = a_1 + d(n - 1)$

We substitute the values to get,

$a_n = 8+ 3(n - 1)$

Alex $8000 in a savings account that earns 3.25 % annually. How much will he earn in interest in 6 months?

kotegsom [21]

<h3>Answer: $130</h3>

=======================================================

Explanation:

I'm assuming the bank is using simple interest (instead of compound interest).

If so, then,

i = P*r*t

i = 8000*0.0325*0.5

i = 130

The amount of interest is $130

In the formula above, I used

P = 8000 = amount deposited
r = 0.0325 = annual interest rate in decimal form
t = 6/12 = 0.5 years, which means you don't use t = 6. We don't use t = 6 because the interest rate is on an annual basis, and not a 6-month basis.
