$1.\\g(x)=x+10\to g(0)=0+10=10\\\\f(x)=3x\to f(g(0))=f(10)=3\cdot10=30$

$2.\\g(x)=x+12\\f(x)=4-2x\to f(g(x))=4-2(x+12)=4-2x-24=-2x-20$

$3.\\y=9x+15\ \ \ |-15\\9x=y-15\ \ \ |:9\\\\x=\dfrac{y-15}{9}$
Answer: $y=\dfrac{x-15}{9}=\dfrac{1}{9}x-\dfrac{5}{3}$

Answer:

Y Intercept: 0, 2.5

X Intercept: 3.5, 0

Explanation:

An Intercept is where a line crosses an axis. A Y Intercept is for the Y axis and the X intercept is for the X axis.

Also when writing coordinates, the x coordinate comes before the y one.

Hope this helps :)

Find the complete factored form of the polynomial -44a^3 + 20a^6

irakobra [83]

Answer:

$4a^3(5a^3-11)$

Step-by-step explanation:

→Take out the GCF (Greatest Common Factor). The GCF is $4a^3$ because both $-44a^3$ and $20a^6$ can be divided by it, like so:

$-44a^3+20a^6$

$4a^3(5a^3-11)$

The surface are of the right cone is 176 sq.units. Option A) is the correct answer.

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

<u>step 1</u> :

Radius of the cone, <em>r = 4</em>

Height or length of the cone,<em> h = 10</em>

<u>step 2</u> :

Total surface area of right cone = πrh + πr^2

= (π $\times$ 4 $\times$ 10) + ( π $\times$ 4^2)

= 40π + 16π

= 56 π = 56 $\times$ 3.14

= 176 sq.units
