Find the length and width of a rectangle whose perimeter is

Hoochie [10]

Answer:

11 and 7

Step-by-step explanation:

Perimeter is all of the sides added together

11+11+7+7=36

Area of a rectangle is length x width

7*11=77

The answers are 7 and 11 for the length and width

Whether which one is the width and which is the length depends on which side is the longest.

Suppose f (x) = x^2. Find the graph of f(x+2)

$\bf ~~~~~~~~~~~~\textit{function transformations}

~~~~y={{ A}}({{ B}}x+{{ C}})+{{ D}}

f(x)={{ A}}\sqrt{{{ B}}x+{{ C}}}+{{ D}}

f(x)={{ A}}(\mathbb{R})^{{{ B}}x+{{ C}}}+{{ D}}

f(x)={{ A}} sin\left({{ B }}x+{{ C}} \right)+{{ D}}

\\\\
\bullet \textit{ flips it sideways if }{{ B}}\textit{ is negative}\\
~~~~~~\textit{reflection over the y-axis}$

$\bf \bullet \textit{ horizontal shift by }\frac{{{ C}}}{{{ B}}}\\
~~~~~~if\ \frac{{{ C}}}{{{ B}}}\textit{ is negative, to the right}\\\\
\left. \qquad \right. if\ \frac{{{ C}}}{{{ B}}}\textit{ is positive, to the left}\\\\

~~~~~~if\ {{ D}}\textit{ is negative, downwards}\\\\

\bullet \textit{ period of }\frac{2\pi }{{{ B}}}$

with that template in mind,

$\bf f(x)=x^2\qquad \quad f(x+2)=(x+2)^2\implies f(x+2)=\stackrel{A}{1}(\stackrel{B}{1}x\stackrel{C}{+2})^2\stackrel{D}{+0}$

C = 2 B = 1 C/B = 2/1 or +2, horizontal left shift of 2 units

f(x) shifted left by 2 units is f(x+2).

Find the missing value.

Fudgin [204]

Answer:

$3125

Step-by-step explanation:

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

A = 250(1 + 0.25)ⁿ

A = (312.5)ⁿ

n = 10

A = $3125

A = I
