Answer:

Step-by-step explanation:

Fill in each function's argument and do the arithmetic.

$h(g(f(\sqrt{10})))=h(g(2(\sqrt{10})^2-7))=h(g(2\cdot 10-7))=h(g(13))\\\\=h(\dfrac{4-13}{9})=h(\dfrac{-9}{9})=h(-1)\\\\=\sqrt{-(-1)+3}=\sqrt{4}=\boxed{2}$

Answer:

"2.660503478" would be the right answers to the key statement.

Step-by-step explanation:

Drawing 5 balls out of 69 can be done in ( $\frac{69}{5}$ )

= $\frac{69\times 68\times 67\times 66\times 65}{5!}$

Drawing 1 ball out of 26 red balls can be done in ( $\frac{26}{1}$ )

= $26$

Then the chance of drawing 5 out of 69 balls including 1 out of 26 red balls and then both matching the jackpot

= $\frac{1}{11238513\times 26}$

= $\frac{1}{292201338}$

Since the sum of the jackpot is $193-106 and then one ticket costs $2, the estimated value of buying one ticket again for jackpot is $2.

= $\frac{1}{292201338}\times 193\times 10^6+\frac{292201338-1}{292201338}\times 2$

= $2.660503478$

If f(a) = 2a ^ 3 + 3a ^ 2 + 5 , find f(- 2)

UkoKoshka [18]

<h2>Answer: 1</h2>

Step-by-step explanation:

Just plug in -2 anywhere you see an <u>a</u>

$f(a)=2a^3+3a^2+5\\f(-2)=2(-2)^3+3(-2)^2+5\\f(-2)=2(-8)+12+5\\f(-2)=-16+12+5\\f(-2)=1$
