<h2>Solving Piecewise Functions</h2><h3>Answer:</h3>

$f(1) = -6$

<h3>Step-by-step explanation:</h3>

Given:

$f(x) = \begin{cases} -(x +5)^2 &\text{for} &x \leqslant -3 \\ -2x -4 &\text{for} &-3 < x \leqslant 1 \\ 5 &\text{for} &x > 1 \end{cases}$

$f(1) = -2x -4 \space , \space x = 1 \\ f(1) = -2(1) -4 \\ f(1) = -2 -4 \\ f(1) = -6$

300-7 [4 (3+5)]+3 to the 3rd power

Allisa [31]

The expression to solve is the
300-7 [4 (3+5)] + 3 to the 3rd power
3 to the third power means 3³, so
300-7 [4(3+5)]+3³
= 300 - 7 [4(8)] + 27
= 300 - 7[32] + 27
= 300 - 224 + 27
= 76 + 27
= 103
so, by solving this we get 103

If your starting salary is $40,000 and you receive a 4.2% raise every year, how much TOTAL money will you make in 15 years?

Oliga [24]

The first year, the amount is 40,000

the second year is 40000 + 4.2% of 40000, or 0.042 * 4000, so 40000+(0.042*4000)
common factoring that we get 40000(1 + 0.042), or just 40000(1.042)

in short, the starting amount is 40000, and to get the next term's value you'd use the "common ratio" of 1.042, namely the multiplier of 1.042.

for the third year it'll be 40000(1.042) + (0.042 *40000(1.042) ), again, common factoring that

40000(1.042)(1 + 0.042) or 40000(1.042)(1.042) or 40000(1.042)²

therefore,

$\bf \qquad \qquad \textit{sum of a finite geometric sequence}\\\\
S_n=\sum\limits_{i=1}^{n}\ a_1\cdot r^{i-1}\implies S_n=a_1\left( \cfrac{1-r^n}{1-r} \right)\quad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
r=\textit{common ratio}\\
----------\\
a_1=40000\\
r=1.042\\
n=15
\end{cases}
\\\\\\
S_{15}=40000\left( \cfrac{1-1.042^{15}}{1-1.042} \right)\implies S_{15}\approx 40000\left( \cfrac{-0.8536}{-0.042} \right)
\\\\\\
S_{15}\approx 812951.42$

Gina ate 3/4 of an apple pie. greg ate 1/8 of the same pie. how much of the Apple pie was left?

miskamm [114]

There would be 1/8 of the pie left,
you have to add 3/4 and 1/8 to find the total eaten and then subtract it by 8/8 (the total) which would give you your answer.

Hope it helps
