Answer:

The second option is the answer.

Step-by-step explanation:

Do f(x) first, and then plug that into g(x).

$f(x)=\sqrt{x+3}$

$(g o f)(x) = \frac{\sqrt{x+3}^{2}+2 }{\sqrt{x+3}}=\frac{x+5}{\sqrt{x+3}}$

What is the answer of this equation [x+3]<4

mariarad [96]

Answer:

x<1 x>-7

Step-by-step explanation:

|x+3|<4

We know x+3<4 and x+3>−4

x+3<4 (Condition 1)

x+3−3<4−3 (Subtract 3 from both sides)

x<1

x+3>−4 (Condition 2)

x+3−3>−4−3 (Subtract 3 from both sides)

x>−7

Answer:

x<1 and x>−7

Tony is pouring milk for student lunches. She knows that 3 quarts of milk contain 12 cups. How many cups can she pour with 7 qua

Evgesh-ka [11]

Answer:

7 quarts = 28 cups

10 cups = 2.5 quarts

Step-by-step explanation:

In order to solve the two different questions in the problem, starting with a ratio of the number of quarts to the number of cups would be helpful:

$\frac{quarts}{cups}=\frac{3}{12}=\frac{1}{4}$

So, for every 1 quart of milk, she can pour 4 cups. Using this ratio, we can set up equivalent ratios, or proportions, to solve for the missing value. For the first question, we need to know that amount of cups in 7 quarts:

$\frac{1}{4}=\frac{7}{x}$

We can solve for 'x' by multiplying the numerator and denominator by the same factor, in this case '7'. So, 4 x 7 = 28 cups.

Next, we need to solve for the amount of quarts needed for 10 cups:

$\frac{1}{4}=\frac{x}{10}$

4 x 2.5 = 10, so we need to multiply the numerator by 2.5: 1 x 2.5 = 2.5 quarts.

An urn contains 8 green and 9 white balls. Six balls are randomly drawn from the urn in succession, with replacement. That is, a

gulaghasi [49]

Answer:

The probability is 0.022

Step-by-step explanation:

Firstly, we need to get the total number of balls in the urn

mathematically, we have this as ;

8 + 9 = 17

now, the probability of selecting a white ball will be the number of white balls divided by the total number of balls

Mathematically, we have this as 9/17

Now, since the event is carried out with replacement, the probability for the six times is the same

So, we have the probability as;

(9/17)^6 = 0.022
