Question
Which of the following is the domain of the function G(F(x))? F(x) = x + 4, G(y) = G(F(x)) = A. All numbers less than or equal to 4 B. All numbers less than or equal to -4 C. All numbers greater than or equal to -4 D. All numbers greater than or equal to 4
Solution 1
Answer: option C. all numbers greater than or equal to -4.

Justification:

1) G(F(x)) means apply first the rule F(x) and then apply the rule G(y) to the outcome of (Fx).

2) Mathematically that is:

G(F(x) = G (x + 4) =

3)Â  The the domain is all the numbers for which the expression inside the root are not negative, i.e x + 4 â‰¥ 0

â‡’ x â‰¥ - 4

That is the option C. all number greater than or equal to - 4.

Question
Josiah has 3 packs of toy animals. Each pack has the same number of animals. Josiah gives 6 animals to his sister stephanie. Then josiah has 9 animals left.how many animals were in each pack?
Solution 1
Let the number of animals in each pack be x.
Total number of animals will be 3x
after Josiah gave 6 animals to his sister the remaining animals were:
3x-6=9
thus sloving for x we have:
3x-6=9
3x-6+6=9+6
3x=15
divide both sides by 3
(3x)/3=15/3
x=5
There were 5 animals in each pack
Question
If 12 1/2% of a sum of money is $40 what is the total sum of money? Solution 1 The total sum of money will be$320.

Let the total sum of money be represented by x.

Based on the information given, the equation to solve the question will be:

12 1/2% Ã— x = 40

0.125x = 40

Divide by 0.125

x = 40/0.125.

x = 320

Therefore, the total sum of money will be $320. Read related link on: brainly.com/question/2805223 Solution 2 12 1/2% = 12.5% 12.5% =$40

1% = 40 Ã· 12.5 = $3.20 100% =$3.20 x 100 = $320 Answer:$320

Question
A ball is launched into the sky at 272 feet per second from the roof of a skyscraper 1,344 feet tall. The equation for the ballâ€™s height h at time t seconds is h = -16t2 + 272t + 1344. When will the ball strike the ground?
Solution 1

Time taken to reach the ball to the ground is 21 seconds. Â  Â  Â  Â  Â  Â  Â  Â  Â

Step-by-step explanation:

Given : A ball is launched into the sky at 272 feet per second from the roof of a skyscraper 1,344 feet tall. The equation for the ballâ€™s height h at time t seconds is .

To find : When will the ball strike the ground?

Solution :

The equation for the ball's height 'h' at time 't' is given by,

When the ball strike the ground the height of the ball became zero.

Substitute h=0 in the given equation,

Taking 16 common,

or

Solve by middle term split,

Reject t=-4 as time can never be negative.

Therefore, Time taken to reach the ball to the ground is 21 seconds.

Question
American cheese 0.45 to 4.26 what is the percent increase
Solution 1
For this case we have the following rule of three:
Â 0.45 ------> 100%
Â 4.26 ------> x
Â Clearing x we have:
Â x = (4.26 / 0.45) * (100)
Â x = 946.6666667%
Â Thus, the percentage of growth is:
Â 946.6666667 - 100 = 846.6666667
Â Rounding:
Â 846.7%
Â
the percent increase is:
Â
846.7%
Question
The average score on a standardized test is 750 points with a standard deviation of 50 points. What is the probability that a student scored more than 850 on the standardized test ?
Solution 1
The probability that student scored more than 850 we shall proceed as follows:
z=(x-Î¼)/Ïƒ
where:
x=850
Î¼=750
Ïƒ=50
thus
z=(850-750)/50
z=2
thus
P(x>850)=1-P(x<850)=1-P(z<2)=1-0.9772=0.0228
