Answer:

a. number of periods over which interest is calculated on the loan

Step-by-step explanation:

A formula should always be accompanied by an explanation of what it calculates and the meaning of each of its variables. This formula calculates P, the periodic payment on a loan of n periods at interest rate i (compounded) per period. The principal amount of the loan is PV.

___

The same formula can also be used to calculate an annuity from which payment P is received at the end of each of n periods. The amount invested is PV and the interest rate per period (compounded per period) is i.

What are the zeros of this polynomial and state their multiplicity at each <br> y=(x-5)(x+2)^2

N76 [4]

Answer:

Step-by-step explanation:

The zeros of a polynomial are the x-intercepts of the function. To find them, we factor the polynomial and set each factor equal to 0.

This polynomial is already factored so set each to 0 and solve for x.

$x-5=0\\x=5\\(x+2)^{2}=0 \\(x+2)=0\\x=-2$

This means x=-2, 5. Each zero or root has a multiplicity - the number of times the factor occurs. This is also known as the exponent of the factor expression.

(x+5) occurs once since it has exponent 1.

$(x+2)^{2}$ occurs twoce since it has exponent 2.

x=5 mult. 1, x=-2 mult. 2

What is the inverse of function f f(x)=√x +7

taurus [48]

Answer: f⁻¹(x)=(x-7)²

Step-by-step explanation:

To find the inverse function, we want to switch the y with the x and vice versa. Then we solve for y.

$y=\sqrt{x} +7$ [switch y with x and x with y]

$x=\sqrt{y} +7$ [subtract both sides by 7]

$x-7=\sqrt{y}$ [square both sides]

$y=(x-7)^2$

Now, we know that f⁻¹(x)=(x-7)².

20 pts and brainiest if correct

amid [387]

We have 1 square with side length 8 inches, and 4 triangles with a base length of 8 inches and a height of 15.

Surface area = (8 × 8) + 4(0.5 × 8 × 15)

The first part of this equation is the area of the square

The second part is the area of a triangle, multiplied by 4 (because there are 4 triangles)

= 64 + 4(60)

= 64 + 240

= 304 in²

The total surface area is 304 square inches.

Let me know if you need any clarifications, thanks!

(9⋅10

cestrela7 [59]

Answer:

A. -18·10^6

Step-by-step explanation:

The rules of exponents apply to powers of 10 used in scientific notation. The associative and commutative properties of multiplication also apply.

<h3>Application</h3>

(a^b)(a^c) = a^(b+c)

The numerical product is ...

$(9\cdot10^9)\cdot(-2\cdot10^{-3})=(9)(-2)(10^{9-3})=\boxed{-18\cdot10^6}$

<em>Additional comment</em>

Expressed in scientific notation, the result would be ...

$-1.8\cdot10^7$

Your calculator can perform this multiplication for you.
