Not a function fails the vertical line test

Step-by-step explanation:

This is not a function. The value of x = -1 goes to two different values of y

This would fail the vertical line test

Find the value of annuity if the periodic deposit is $250 at 5% compounded quarterly for 10 years

mylen [45]

Answer:

The value of annuity is $P_v = \$ 7929.9$

Step-by-step explanation:

From the question we are told that

The periodic payment is $P = \$ 250$

The interest rate is $r = 5\% = 0.05$

Frequency at which it occurs in a year is n = 4 (quarterly )

The number of years is $t = 10 \ years$

The value of the annuity is mathematically represented as

$P_v = P * [1 - (1 + \frac{r}{n} )^{-t * n} ] * [\frac{(1 + \frac{r}{n} )}{ \frac{r}{n} } ]$ (reference EDUCBA website)

substituting values

$P_v = 250 * [1 - (1 + \frac{0.05}{4} )^{-10 * 4} ] * [\frac{(1 + \frac{0.05}{4} )}{ \frac{0.08}{4} } ]$

$P_v = 250 * [1 - (1.0125 )^{-40} ] * [\frac{(1.0125 )}{0.0125} ]$

$P_v = 250 * [0.3916 ] * [\frac{(1.0125)}{0.0125} ]$

$P_v = \$ 7929.9$

A girl can run 6 2/3 metres in one second. How long will it take her to run 100 metres?

Crank

Answer:

15 seconds

Step-by-step explanation:

How did i get this answer? It is apparent that the girl is capable of running 6 2/3 metres per one second and she must run 100 metres.

First, let's convert 2/3 into a decimal so that it is easier to calculate later. 2/3=0.667 (you can also just do 2 divide by 3 and will end up with the same number)

Now our numbers are 6.667 and 100. Let's divide 100 by 6.667 which estimates to 15

To make the expression 4x-2 + (2x + 4) equivalent to 2(6x + 7), what must be the value in the box?

podryga [215]

$4x - 2 + (2x + 4) = 2(6x + 7) \\$

$4x - 2 + 2x + 4 = 12x + 14$

Simplification

$6x + 2 = 12x + 14$

Subtract sides 2

$6x + 2 - 2 = 12x + 14 - 2$

Simplification

$6x = 12x + 12$

Subtract sides -12x

$6x - 12x = 12x - 12x + 12$

Simplification

$- 6x = 12$

Divided sides by -6

$\frac{ - 6}{ - 6}x = \frac{12}{ - 6} \\$

$x = - 2$

It is must be in the box buddy.

And we're done...♥️♥️♥️♥️♥️
