Answer:

Step-by-step explanation:

Write 34 in tens and units.

34 = 30 + 4

9(30 + 4)

9 * 30 = 270

9* 4 = 36

270 + 36 = 306

After awhile if your practice enough, you can do them in your head.

Find the domain of f/g

san4es73 [151]

Answer:

C. All real numbers except 3/4

Step-by-step explanation:

We are given

$f(x)=3x^2+x^4+2$

$g(x)=4x-3$

Firstly, we will find f/g

$\frac{f}{g}=\frac{3x^2+x^4+2}{4x-3}$

Domain:

We know that domain is all possible values of x for which any function is defined

so, we know that denominator of any function can not be zero

so, firstly we set denominator =0

and then we can solve for x

$4x-3=0$

Add both sides by 3

$4x-3+3=0+3$

$4x=3$

$x=\frac{3}{4}$

so, this function is defined for all values of x except at

$x=\frac{3}{4}$

Domain will be

All real numbers except 3/4

A lottery game has balls numbered 1 through 21. What is the probability of selecting an even numbered ball or an 8? Round to nea

Viktor [21]

Answer: 0.476

Step-by-step explanation:

Let A = Event of choosing an even number ball.

B = Event of choosing an 8 .

Given, A lottery game has balls numbered 1 through 21.

Sample space: S= {1,2,3,4,5,6,7,8,...., 21}

n(S) = 21

Then, A= {2,4,6,8, 10,...(20)}

i.e. n(A)= 10

B= {8}

n(B) = 1

A∪B = {2,4,6,8, 10,...(20)} = A

n(A∪B)=10

Now, the probability of selecting an even numbered ball or an 8 is

$P(A\cup B)=\dfrac{n(A\cup B)}{n(S)}$

$=\dfrac{10}{21}\approx0.476$

Hence, the required probability =0.476
