The age of Sydney is 25 years old

<u>Solution:</u>

Given that Devaughn is 7 years older than Sydney

The sum of their ages is 57

Let the age of Sydney be "x"

Then according to given information,

Age of Devaughn = x + 7

Now, Sum of Sydney age and Devaughn age = 57

Substituting the values we get,

x + x + 7 = 57

2x + 7 = 57

2x = 57 - 7

2x = 50

x = 25

"x" represents age of Sydney. Hence Sydney's age is 25 years old

25.
25 + 32 = 57

Paul deposited $95,000 in a savings account that pays 4% interest compounded daily. What is his balance at the end of six months

Arada [10]

Answer:

$\$96,919.02$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=6/12=0.5\ years\\ P=\$95,000\\ r=4\%=4/100=0.04\\n=365$

substitute in the formula above

$A=95,000(1+\frac{0.04}{365})^{365*0.5}$

$A=95,000(1+\frac{0.04}{365})^{182.5}=\$96,919.02$

You invest $3000 in an account that pays simple interest of 7% for 30 years. how much will you have at the end of 30 years?

nekit [7.7K]

$9,300
First, multiply your beginning amount by the percent of interest: 3,000x0.07 = 210
Then, multiply your interest times the number of years:
210x30 = 6,300
Add you interest to your initial amount:
3,000 + 6,300 = 9,300

(b)The graph of y = g(x) is shown. Draw the graph of g(2x). Will award 100 Brainly points

ivanzaharov [21]

Using the stated transformation, the graph of g(2x) is given at the end of the answer.

<h3>Horizontal stretch and compression</h3>

An horizontal stretch or an horizontal compression happens when a constant is multiplied at the domain of the function, as follows:

g(x) = f(ax).

The definition of stretch or compression depends on the value of the constant a, as follows:

If a > 1, it is a compression by a factor of 1/a.

If a < 1, it is a stretch by a factor of 1/a.

In this problem, the rule is:

f(x) = g(2x).

Meaning that f(x) is an horizontal compression by a factor of 1/2 of g(x), and then the vertices are given as follows:

(0,0).

(1,-4).

(2,-2).

That is, in each vertex, the x-coordinate was divided by 2, and thus the graph with these vertices is given at the end of the answer.
