Hi there.

The answer is g(0) = 3.

Explanation:

Given three functions with specified domains. The first and three functions both do not have x = 0 as a part of the domain. We can clear both functions.

Our main function then is currently —

$g(x) = 3$

You might be wondering how are we gonna find the x-value if there is no x-term?

That is to do nothing. If there is no x-term to substitute then we answer only the constant.

$g(0) = 3$

In February, Alec had 1,586 visitors to his website. In March, he had 1,352 visitors to his website. What is the percentage decr

Deffense [45]

Answer:

The percentage decrease of the number of visitors to Alec's website from February to March is 14.8 %

Step-by-step explanation:

Explanation:

Percent decrease is a measure of percent change, which is the extent to which something loses value.

Step 1:

Find out the difference (decrease) between the number of visitors in march and February

Decrease =number of visitors in Fe bury- Number of vsitors in march

Decrease= 1,586- 1,352

Decrease =234

Step 2:

Divide the decrease by the original number of visitors and multiply the answer by 100.

Percent decrease= $\frac{Decrease }{ Original Number }\times100$

Percent decrease= $\frac{236}{1586}\times100$

Percent decrease= $0.148\times100$

Percent decrease =14.88

Shawna invests $5,048 in a savings account with a fixed annual interest rate of 4% compounded 12 times per year. How long will i

Elena-2011 [213]

Answer:

5 years

Step-by-step explanation:

In the question we are given;

Amount invested or principal amount as $5048
Rate of interest as 4% compounded 12 times per year
Amount accrued as $6,163.59

We are required to determine the time taken for the money invested to accrue to the given amount;

Using compound interest formula;

$A=P(1+\frac{r}{100})^n$

where n is the interest period and r is the rate of interest, in this case, 4/12%(0.33%)

Therefore;

$6,163.59=5,048(1+\frac{0.333}{100})^n$

$1.221=(1+\frac{0.333}{100})^n$

$1.221=(1.0033)^n$

introducing logarithms on both sides;

$log1.221=log(1.0033)^n\\n=\frac{log1.221}{log1.0033} \\n=60.61$

But, 1 year = 12 interest periods

Therefore;

Number of years = 60.61 ÷ 12

= 5.0508

= 5 years

Therefore, it will take 5 years for the invested amount to accrue to $6163.59

Divide line segments

ser-zykov [4K]

tis noteworthy that the segment contains endpoints of A and C and the point B is in between A and C cutting the segment in a 1:2 ratio,

$\bf \textit{internal division of a line segment using ratios} \\\\\\ A(-9,-7)\qquad C(x,y)\qquad \qquad \stackrel{\textit{ratio from A to C}}{1:2} \\\\\\ \cfrac{A\underline{B}}{\underline{B} C} = \cfrac{1}{2}\implies \cfrac{A}{C}=\cfrac{1}{2}\implies 2A=1C\implies 2(-9,-7)=1(x,y)\\\\[-0.35em] ~\dotfill\\\\ B=\left(\frac{\textit{sum of "x" values}}{\textit{sum of ratios}}\quad ,\quad \frac{\textit{sum of "y" values}}{\textit{sum of ratios}}\right)\\\\[-0.35em] ~\dotfill$

$\bf B=\left(\cfrac{(2\cdot -9)+(1\cdot x)}{1+2}\quad ,\quad \cfrac{(2\cdot -7)+(1\cdot y)}{1+2}\right)~~=~~(-4,-6) \\\\[-0.35em] ~\dotfill\\\\ \cfrac{(2\cdot -9)+(1\cdot x)}{1+2}=-4\implies \cfrac{-18+x}{3}=-4 \\\\\\ -18+x=-12\implies \boxed{x=6} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{(2\cdot -7)+(1\cdot y)}{1+2}=-6\implies \cfrac{-14+y}{3}=-6 \\\\\\ -14+y=-18\implies \boxed{y=-4}$
