Answer:

Step-by-step explanation:

Well a relation is a set of points and a function is a relation where every x value corresponds to only 1 y value.

So lets see which x values in these relations have only 1 y value.

A. Well a isn’t a function because the number 3 which is a x value had two y values which are -1 and 4.

B. This relation is a function because there are no similar x values.

C. This is not a function because the x value 4 has two y values which are 4 and -3.

D. This is not a function because the number 1 has 2 and 3 as y values.

Gina invests $1,677 in an account paying 8.61% simple interest annually. How much interest has Gina gained after six years? a. $

enot [183]

Answer:

Option (c) is correct.

The interest gained by Gini in 6 years is $ 866.34

Step-by-step explanation:

Given: Gina invests $1,677 in an account paying 8.61% simple interest annually for 6 years.

We have to calculate the interest gained by Gina in 6 years.

Using formula for simple interest

$S.I.=\frac{P\times I\times T}{100}$

Where,

S.I = simple interest

P is principal

R is interest rate

T is time

Given : P = $ 1677

R = 8.61%

T = 6 years

Substitute, we get,

$S.I.=\frac{1677\times 8.61\times 6}{100}$

Simplify, we get,

S.I. = $ 866.3382

Rounding off to nearest hundred we get, Interest is $866.34

Thus, the interest gained by Gini in 6 years is $ 866.34
