Answer:  log function

The rule is log(x^y) = y*log(x)

The exponent y is pulled down and placed as a coefficient, so to speak.

The total simple interest on $1600 invested for five years is $224. What is the percentage rate per annum?
mash [69]

Answer:

The percentage rate per annum is 2.8%

Step-by-step explanation:

We need to multiply the principal by the time, then divide the interest by the product of P×T, so:

1,600 × 5 = 8,000

224 ÷ 8,000 = 0.028

Then we convert our final product to a percentage.

0.028 to a percent is 2.8%

Simplify the expression below.
Ostrovityanka [42]

Answer: OPTION C.

Step-by-step explanation:

Given the following expression:

4x(3x- 7) - 19x^2

You can simplify this expression applying these steps:

First step: You must apply Distributive property:

=12x^2-28x-19x^2

Second step: You need to add the like terms.

Then, you get:

=-7x^2-28x

You can observe that this simplified expression matches with the expression provided in Option C.

Write a polynomial in standard form that meets the following conditions. Assume a=1 and your function is f(x), The zeros are 5 a
jeka57 [31]

Polynomials are equations that uses variables and several terms

The polynomial in standard form is f(x) = x^2 - x -20

<h3>How to determine the polynomial</h3>

The polynomial has 2 zeros.

So, the form of the polynomial is:

f(x) = a(x - x1)(x - x2)

The zeros of the polynomial are 5 and -4.

So, the equation becomes

f(x) = a(x - 5)(x + 4)

The value of a = 1.

So, we have;

f(x) = 1(x - 5)(x + 4)

This gives

f(x) = (x - 5)(x + 4)

Expand

f(x) = x^2 - x -20

Hence, the polynomial in standard form is f(x) = x^2 - x -20
