Answer:

b) dilation

Step-by-step explanation:

Translation:

Figure has the same size, just in different positions.

Dilation:

FIgure has different size.

In this question:

We have function $f(x) = x$ .

And also, we have function $g(x) = \frac{x}{4}$ , that is, the figure f changes in size, is divided by 4. So it is a dilation.

The area of a parallelogram is 91.2cm2, base is l2cm. Find its height.

bulgar [2K]

Answer:

7.6 cm

Step-by-step explanation:

The formula to find the area of the parallelogram is :

Area = Base × Height

<em>They have already given,</em>

Area = 91.2 cm²

Base = 12 cm

Height =?

To find the height, let the height be h.

<u>Let us solve it now.</u>

Area = Base × Height

91.2 cm² = 12 cm × h

Divide both sides by 12.

7.6 cm = h

Therefore, the height is 7.6 cm.

If $3000 is deposited in an account that pays 5% interest, what is the difference in the amount after 4 years between the amount

Triss [41]

$\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$3000\\
r=rate\to 5\%\to \frac{5}{100}\to &0.05\\
t=years\to &4
\end{cases}
\\\\\\
A=3000(1+0.05\cdot 4)\implies \boxed{A=3600}\\\\
-------------------------------\\\\$

$\bf \qquad \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to &\$3000\\
r=rate\to 5\%\to \frac{5}{100}\to &0.05\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{annually, thus once}
\end{array}\to &1\\
t=years\to &4
\end{cases}$

$\bf A=3000\left(1+\frac{0.05}{1}\right)^{1\cdot 4}\implies A=3000(1.05)^4\implies \boxed{A=3646.51875}\\\\
-------------------------------\\\\
\stackrel{\textit{compounded interest}}{3646.51875}~~-~~\stackrel{\textit{simple interest}}{3600}$
