A.find the price elasticity of demand at the equilibrium points? quantity demand=72-8p and quantity supply=-24 +24p. B.substitutes the equation.
Answer:
p = 3
Step-by-step explanation:
The price elasticity of demand at the equilibrium points occurs when quantity demand equals quantity supply.
So,
72-8p= -24 +24p
Taking like terms together,
72+24 = 24p+8p
96 = 32p
p = 3
Hence, the price elasticity of demand is at p = 3.

What are the zeros of f(x) = x^2 - x- 12? Please explain if you can.
Answer:
4 and -3
Step-by-step explanation:
So our function is f(x) = x² - x -12
We need to find factors such that 0 = x² - x -12
So, it looks something like this 0 = (x - a)(x - b)
We know that the first term is x², which can only be obtained if we multiply x by another x.
Now, we need to find the other terms a and b. We know that a × b = -12
The correct answer would be that a = 4 and b = -3
0 = (x - 4)(x + 3)
We know this because, if we multiply this out, we get x² + 3x -4x -12, which can be simplified to x² -x -12.
Our zeroes are the values of x that this equation 0 = (x - 4)(x + 3) is true. What values of x will make this zero?

Boys = 84 * 2 = 168
Total = 252
Answer:
Step-by-step explanation:
no of girls in grade 3 = 84
by the question no of boys are twice the number of girls so
no of boys = 2 * 84 = 168
Total no of pupil in grade 3

the rate you found in (a)?
Answer:
21.25 days
Step-by-step explanation:
We first need to find the rate that he read the book for the first 5 days:
180 (pages)/5 (days)= 36
So he reads 36 pages a day. Now we need to find how many days it will take him to read the whole book, while reading 36 pages a day.
765 (total pages)/36 (pages he reads in a day) = 21.25

George wants to borrow $30,000 to purchase a car. After looking at a monthly budget he realizes that all he can afford to pay per month is $350. The dealership is offering a 4.77% loan. When George hears how much interest he will pay over the life of the loan, he decides to cut back on his entertainment expenses and pay $400 per month. How much in interest will George save by paying an extra $50 per month? Hint: Round any loan length calculations to the nearest quarter of a year.
Answer:
$8,670
Step-by-step explanation:
George will save $1,431 in interest by paying an extra $50 per month.
What exactly is a monthly payment?A monthly payment is a payment made every month to pay off loans or advances. It's similar to EMI.
First, you need to calculate the length of the loan in years.
Since George can afford to pay $350 per month, and he wants to borrow $30,000, the length of the loan in months is 30,000 / 350 = 85.71428571 months.
To convert this to years, you can divide the number of months by 12: 85.71428571 months / 12 months/year = 7.142857143 years.
You should round this to the nearest quarter of a year, which is 7.25 years.
Next, you need to calculate the total amount of interest that George will pay over the course of the loan. To do this, you can use the formula:
interest = principal x rate x time
In this formula, "principal" is the amount of money that George is borrowing, "rate" is the interest rate of the loan, and "time" is the length of the loan in years. Plugging in the values that you know, you get:
interest = 30000 x 0.0477 x 7.25 = 10,374.75
Now that you know how much interest George will pay if he pays $350 per month, you can use the same formula to calculate how much interest he will pay if he pays $400 per month. You will get a slightly different loan length because the $400 payment will allow him to pay off the loan faster.
The new loan length will be 30,000 / 400 = 75 months.
Converting this to years gives 75 months / 12 months/year = 6.25 years. Rounding this to the nearest quarter of a year gives 6.25 years.
Using the formula again, you get:
interest = 30000 x 0.0477 x 6.25 = 8,943.75
To find out how much George will save by paying $50 more per month, you can subtract the amount of interest he will pay with the higher monthly payment from the amount of interest he will pay with the lower monthly payment:
10,374.75 - 8,943.75 = 1,431
This means that he will save $1,431 in interest by paying an extra $50 per month.

2. A conical tank has height 3 m and radius 2 m at the top. Water level is rising at a rate of 2.1 m/min when it is 1.8 m from the bottom of the tank. At what rate is water flowing in? (Round your answer to three decimal places.)
Answer:
Step-by-step explanation:
S=4πr²
ds/dt=4π×2r×dr/dt=8πr dr/dt
dr/dt=60 cm/min
ds/dt=8π×60r=480πr
r=16,t=0
