Factorise completely 2y^2-4y

Serga [27]

To factor an expression, first you have to find the GCF or Greatest Common Factor of all of the pieces of the expression.

The GCF of 2y^2 and -4y is 2y

So, to factor this expression, we need to divide all of the pieces of the expression by the GCF.

2y(y-2)

2y^2 - 4y in completely factored form is 2y(y-2)

Leonard owns a business earning $37,800 in profits. These profits are appreciating at about 2.3% each year. What are Leonard's p

satela [25.4K]

Answer:

B. $45341.60

Step-by-step explanation:

Given:

Initial profit = $37800
Rate of appreciation = 2.3% per year

The equation for this:

$P(t) = 37800*(1 + 0.023)^t = 37800*1.023^t$

Find the value of P(8):

$P(8) = 37800*1.023^8 = 45341.60$

Correct choice is B

A sphere has a volume of Vequals=3600 in cubedin3. Find its surface area.

Mice21 [21]

$\bf \textit{volume of a sphere}\\\\
V=\cfrac{4}{3}\pi r^3\qquad 
\begin{cases}
r=radius\\
------\\
V=3600
\end{cases}\implies 3600=\cfrac{4}{3}\pi r^3
\\\\\\
3600=\cfrac{4\pi r^3}{3}\implies \sqrt[3]{\cfrac{3\cdot 3600}{4\pi }}=\boxed{r}\\\\
-----------------------------\\\\
\textit{surface area of a sphere}\\\\
S=4\pi r^2\implies S=4\pi \left(\boxed{\sqrt[3]{\cfrac{3\cdot 3600}{4\pi }}} \right)^2$

simplify away
