Explanation:
1) f(x) is not a function because there is an ambiguity for x = 4.
x = 4 belongs to both intervals - 2 ≤ x ≤ 4 and x ≥ 4
Then you find two different possible images for x: 0 and -(2)^2 = - 4.
That makes that f(x) be not a function.
2) similar thing happens with g(x)
as per the given relation the value of g(x) for x = 2 is 4 and 4+1 = 5. Which makes that g(x) be not a function.
3) j(x) is not a function because the image of x = -4 is -3(-4) = 12 and 3.
4) h(x) is a function, because there is not any ambiguity in its definition, for every x in its domain there is only one image h(x).

Bill takes a loan of 9,000.00 at a 8% simple interrst rate for 6 years a.how much interest will he pay after 2 years? b. how much interest will he pay in total for the loan
help plz
Answers
Bill will pay an interest of $1440 after 2 years and a total interest of $4320 over 6 years.
Explanation:The subject of your question is related to simple interest calculation. The formula to calculate the simple interest is I = P * R * T, where I is the interest, P is the principal amount (initial loan), R is the annual interest rate in decimal form and T is time in years.
So when you ask 'how much interest will Bill pay after 2 years?', you plug in your values as follows: I = $9000 * 0.08 * 2 which calculates to $1440.
For the total interest Bill will pay over the 6 years, we substitute the values into the formula again but this time T = 6. So, I = $9000 * 0.08 * 6 which calculates to $4320.

Bill will pay $1,440.00 in interest after 2 years and a total of $4,320.00 in interest for the entire loan period of 6 years.
Simple interest can be calculated using the formula Interest = Principal × Rate × Time (I = PRT).
Part A: Interest After 2 YearsThe principal amount is $9,000.00, the interest rate is 8%, and the time is 2 years.
Interest = 9,000 × 0.08 × 2 = 1,440Bill will pay interest of $1,440.00 after two years.
Part B: Total Interest for the LoanAgain, using the same formula but for 6 years:
Interest = 9,000 × 0.08 × 6 = 4,320Bill will pay a total of $4,320.00 in interest over the entire loan period.

If 10*10 is 100 and 100*100 is 10000 what is 10000*10000???? ; )
Answers
You just have to count the zeros..
10*10 (2 zero) = 100
100*100 (4 zero) =10 000
10 000*10 000 (10 zero) = 10 000 000 000
10000 * 10000 is equivalent to 10,000,000
10² is 10 × 10, which equals 100.
10⁴ is 100 × 100, which equals 10,000.
Following this pattern,
we see that large numbers can be simplified using exponents:
The number 10,000 can be written as 10⁴ because:
10 × 10 × 10 × 10 = 10,000
Now, to calculate 10,000 × 10,000:
10,000 is 10⁴, so this is:
(10⁴) × (10⁴) = 10⁸.
So, 10000 * 10000 = 10⁸ = 100,000,000.
So, 10000*10000 is 100,000,000.

When Julia dumped out the big jar of dimes and nickles she found 287 coins. If there was $20.50 in the jar, how many of each kind of coin was there??
Don't answer this unless you actually are answering the question!!! If you have any questions, or it doesn't make sense, please say something in the "Ask for Details" section.
Thanxs again!!!
Answers
0.05N + 0.10D = 20.50
While N = The amount of nickels, and D = The amount of dimes.
Since N = 164, and D = 123. It would add up to 287 coins. 164 + 123 = 287.
Now that you have the number for those two variables, solve the equation for when N = 164, and D = 123.
0.05N + 0.10D = 20.50
0.05(164) + 0.10(123) = 20.50
8.2 + 12.3 = 20.50
20.50 = 20.50
So, there is 164 nickels, and 123 dimes for your answer.
I hope this helps!
~ Notorious Sovereign
Answer:First, you want to solve for the equation for this problem, would be:
0.05N + 0.10D = 20.50
While N = The amount of nickels, and D = The amount of dimes.
Since N = 164, and D = 123. It would add up to 287 coins. 164 + 123 = 287.
Now that you have the number for those two variables, solve the equation for when N = 164, and D = 123.
0.05N + 0.10D = 20.50
0.05(164) + 0.10(123) = 20.50
8.2 + 12.3 = 20.50
20.50 = 20.50
So, there is 164 nickels, and 123 dimes for your answer.

Someone please explain how the GCF of x^4 and x^3 equals x^3. This has me stumped.
Answers
GCF is the greatest common factor. its the value of the factors that are common to both the numbers being compared. In other words the product of the factors that are common to both numbers or the greatest factor common to both numbers.
factors of x⁴ = x * x * x * x = (x * x * x) * x
factors of x³ = x * x * x = (x * x * x)
factors common to both are (x * x * x) Therefore GCF is x³

A water tank has the shape of an inverted right circular cone of altitude 12 ft and base radius 6 ft. if water is being pumped into the tank at a rate of 10 gal/min, approximate the rate at which the water level is rising when it is 3 ft deep
Answers
.. π(1.5 ft)^2 = 2.25π ft^2
The rate of rise is then
.. (10 gal/min)*(77/576 ft^3/gal)/(2.25π ft^2) ≈ 0.18911 ft/min
_____
The rate of change of depth is equal to the rate of change of volume divided by the surface area. Here's how you can get there from derivatives.
V = (1/3)Bh
V' = (1/3)(B'h +Bh')
Here we have B = π(h/2)^2 = (π/4)h^2, so B' = (π/2)h*h'
V' = (1/3)((π/2)*h^2*h' +(π/4)h^2*h')
V' = (π/4)h^2*h'
V' = B*h'
