Let length of rectangle=x and width be y
.`. area=x*y
now new length=x+12x/10=22x/10
width=y-y/5=4y/5
now .....
new area=new length-new width=22x/10*4y/5
new area=88xy/50

The area of the rectangle will decrease because lets say the length is 2 and the width is 1
originally the area of the rectangle is lxw which is 2x1 is 2. But if we increase the length by 120% which will be 2.4 and increase the width decreased by 20% which is 0.8 then if we multiply them using the formula its 1.92 which decreased

What is the compounded interest if $410 is invested for 10 years at 8% compounded continuously
tatiyna
\bf \textit{Continuous Compounding Amount}\\\\
A=Pe^{rt}\qquad \begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$410\\
r=rate\to 8\%\to \frac{8}{100}\to &0.08\\
t=years\to &10
\end{cases}

so, that gives you  the compounded amount, after 10 years, if you want to know how much interest was earned? well, just subtract the Principal from the Amount, or A - P  <--- that's how much interest was earned

A quadratic function passes through the points ( − 5 , − 8 ) and ( 8 , − 8 ) . Find the equation for the line (axis) of symmetry
ra1l [238]

Answer:

The equation for the axis of symmetry is x=1.5.

Step-by-step explanation:

It is given that a quadratic function passes through the points ( − 5 , − 8 ) and ( 8 , − 8 ) .

In the given points y-coordinates are same, i.e., -8. It means both the points lie on the horizontal line y=-8.

If a quadratic function passes through two points (a,c) and (b,c), then the equation for the axis of symmetry is

x=\frac{a+b}{2}

According to the given points a=-5, b=8 and c=-8. Put these value in the above formula.

x=\frac{-5+8}{2}

x=\frac{3}{2}

x=1.5

Therefore the equation for the axis of symmetry is x=1.5.
