Answer:

13a + 2b

Step-by-step explanation:

Use distributive property,

3a + 2(b + 5a) = 3a + 2*b + 2*5a

= 3a + 2b + 10a

Now combine like terms

= 3a +10a + 2b

= 13a + 2b

A fair coin is tossed three times in succession. The set of equally likely outcomes is StartSet HHH comma HHT comma HTH comma TH

liq [111]

The probability of getting exactly zero tails is 1/8.

Step-by-step explanation:

When a fair coin is tossed three time, the set of equally likely outcomes is:

S= {HHH,HHT, HTH, THH, HTT, THT, TTH, TTT}

n(S)=8

Let A be the event that there are exactly zero tails which means there are all heads

Then

A= {HHH}

n(A)=1

$P(A)=\frac{n(A)}{n(S)}\\=\frac{1}{8}$

The probability of getting exactly zero tails is 1/8.

F(x) = square root 32x <br> g(x) = square root 2x

otez555 [7]

Given:

The two functions are:

$f(x)=\sqrt{32x}$

$g(x)=\sqrt{2x}$

To find:

The $(f\cdot g)(x)$ . Assume $x\geq 0$ .

Solution:

We have,

$f(x)=\sqrt{32x}$

$g(x)=\sqrt{2x}$

Now,

$(f\cdot g)(x)=f(x)\cdot g(x)$

$(f\cdot g)(x)=\sqrt{32x}\cdot \sqrt{2x}$

$(f\cdot g)(x)=\sqrt{32x\times 2x}$

$(f\cdot g)(x)=\sqrt{64x^2}$

$(f\cdot g)(x)=8x$

Therefore, the correct option is A.

harina [27]

Answer:

g(-5) = 15

Step-by-step explanation:

Put the value where the variable is and do the arithmetic.

g(-5) = -2(-5) +5 = 10 +5
