Answer:

4th option

Step-by-step explanation:

first two options is where the line starts from 2 if x is 0

here the line starts from -2

both two options are correct as line starts from -2

in the third option, y crosses at 4. which is not here in the graph

as a result we are left with only 4th option.

If you spend $50,000 on new furniture and it is depreciating about 20% per year, how much will it be worth by its third year?

Julli [10]

Answer:

$25,600

Step-by-step explanation:

Given: P = $50,000, r = 20% & t = 3 years

Formula for depreciation is given as:

$A(t) = P\bigg(1-\frac{r}{100}\bigg)^t$

Plugging the values of P, r and t in the above formula, we find:

$A(3) = 50,000\bigg(1-\frac{20}{100}\bigg)^3$

$\implies A(3) = 50,000\bigg(1-\frac{1}{5}\bigg)^3$

$\implies A(3) = 50,000\bigg(\frac{4}{5}\bigg)^3$

$\implies A(3) = 50,000\times\frac{64}{125}$

$\implies A(3) =\$ 25,600$

So, after third year it will be worth by $25,600.

How is an inversely proportional relationship different from a directly proportional relationship?

Semenov [28]

Directly proportional: as one amount increases,
another amount increases at the same rate.

Inversely Proportional: when one value decreases at the same rate that the other increases.

Find the surface area of the solid. Round to two decimal places

Ne4ueva [31]

Check the picture below.

so, to get the area of the triangles, we can simply run a perpendicular line from the top to the base, and end up with a right-triangle with a base of 22 and a hypotenuse of 34, let's find the altitude.

$\bf \textit{using the pythagorean theorem}
\\\\
c^2=a^2+b^2\implies \sqrt{c^2-a^2}=b
\qquad 
\begin{cases}
c=hypotenuse\\
a=adjacent\\
b=opposite\\
\end{cases}
\\\\\\
\sqrt{34^2-22^2}=b\implies \sqrt{672}=b$

so then the surface area of the triangular prism is,

$\bf \stackrel{\textit{left and right}}{2(34\cdot 76)}~~+~~\stackrel{\textit{bottom}}{(44\cdot 76)}~~+~~\stackrel{\textit{front and back}}{2\left[\cfrac{1}{2}(44)(\sqrt{672}) \right]}
\\\\\\
8512~~+~~(44)(\sqrt{672})\qquad \approx\qquad 9652.61036291978$

What are the slope and y-intercept for the graph of y – 7x = 10?

alex41 [277]

Answer:A. slope: 7, y-intercept: 10

Step-by-step explanation:
