G(x) = -2x^3 – 15x^2 + 36x

shusha [124]

Consider the function $G(x) = -2x^3 - 15x^2 + 36x.$ First, factor it:

$G(x) = -2x^3 - 15x^2 + 36x=-x(2x^2+15x-36)=\\ \\=-x\cdot 2\cdot \left(x-\dfrac{-15-\sqrt{513}}{4}\right)\cdot \left(x-\dfrac{-15+\sqrt{513}}{4}\right).$

The x-intercepts are at points $\left(\dfrac{-15-\sqrt{513} }{4},0\right),\ (0,0),\ \left(\dfrac{-15+\sqrt{513} }{4},0\right).$

1. From the attached graph you can see that

function is positive for $x\in \left(-\infrty, \dfrac{-15-\sqrt{513} }{4}\right)\cup \left(0,\dfrac{-15+\sqrt{513} }{4}\right);$
function is negative for $x\in \left(\dfrac{-15-\sqrt{513} }{4},0\right)\cup \left(\dfrac{-15+\sqrt{513} }{4},\infty\right).$

2. Since

$G(-x) = -2(-x)^3 - 15(-x)^2 + 36(-x)=2x^3-15x^2-36x\neq G(x)\ \text{and }\neq -G(x)$ the function is neither even nor odd.

3. The domain is $x\in (-\infty,\infty),$ the range is $y\in (-\infty,\infty).$

The earth has a diameter of 7917.5 mi. What is the arc length of half the earth?

Serhud [2]

Answer:

Arc length is 12436.8m

Step-by-step explanation:

arc length = $\frac{M degree}{360degree}$ * πD

where M is the angle measure of the arc

and D is the diameter

considering the earth as a circle and half the earth as a semi circle the angle measure of the arc will be = 180 degrees

$\frac{180}{360}$ * π * 7917.5 = 12436.8m

Help me please i jave 10 min left HELP

yaroslaw [1]

Answer:

Option (A).

Step-by-step explanation:

$8\frac{4}{5}$ is a mixed fraction and can be written as,

$8\frac{4}{5}=8+\frac{4}{5}$ [Combination of a whole number and a fraction]

When we multiply this mixed fraction by 7,

$7\times 8\frac{4}{5}=7\times (8+\frac{4}{5})$

$=(7\times 8)+(7\times \frac{4}{5})$ [Distributive property → a(b + c) = a×b + a×c]

$=56+\frac{28}{5}$

$=56+5\frac{3}{5}$

$=56+5+\frac{3}{5}$

$=61+\frac{3}{5}$

$=61\frac{3}{5}$

Therefore, $7\times 8\frac{4}{5}=61\frac{3}{5}$ will be the answer.

Option (A) will be the correct option.
