I used the given information and set up my compostie function to be A(r(T) = 3.14(5T)^2 I then used the function to plug in 10,24,48 into the function. I had to convert 10 days into hours because the function was orginally in hours. For (i) 10 hours I set up the equation to be 25(10)^2(3.14) I solved it and got an answer of 7853.982 and rounded the answer up to 8,000 square miles. For(ii) 24 hours I set up the same equation but placed 24 in where 10 was in (i) and got 45238.934 as my answer and I rounded it up to 45,000 square miles. For (iii) 48 hours I repeated the work in (i) and (ii) and just placed 48 the same spot 24 and 10 was in. I solved and got 180953.737 and then rounded it up to 181,000 square miles. For (iv) 10 days, first
2. The thing that ended up taking away that .5 point on my post test is that I made a mistake on my wording for the average rate of change explanation. I need to review my notes a lot about how the proper structure of the average rate of change sentence is supposed to be.
Author's Note: The Choreo awards was amazing because I got meet the actual characters in my book for the first time. It was odd because the people I idolized for so long, suddenly became more human. If you'd like to know all of the juicy details on my night, feel free to PM me :) Also because of this wonderful occasion I didn't have time to write for 2 days, but don't fear, I will try to get back into my writing routine for you guys. This chapter is longer than usual to make up for lost time.
To find the area the students had to use the formula a=r2. Then the students multiply 3.14 by the radius 40 feet squared,which additionally gives 5024 ft for the full circles.After that,the students get 5024, it will be divided by 2 which will then provide the answer 2512ft for the half circles. Then 2512ft will be divided by 2 again giving the answer 1256ft for the quarter circles.The cost of each sprinkler is $11,the football field needs 50 sprinklers,The cost of 50 sprinklers would be $550. The total amount of piping needed to reach all of the sprinklers 1960 ft. The amount of pipes that are needed will cost
16. Given the cost formula, Y = $9,000 + $2.50X, total cost for an activity level of 3,000 units would be:
Assume that Japan and Korea can switch between producing cars and producing airplanes at a constant rate. Table 3 Hours Needed to Make 1 Car Airplane 30 150 50 150 Quantity Produced in 2400 Hours Cars Airplanes 80 16 48 16
C = 200 + .5 YD, where YD = Y – T and T = 200.
3. An airplane accelerates down a runway at 3.20 m/s2 for 32.8 s until is finally lifts off the ground. Determine the distance traveled before takeoff.
2.i) P = 8 - .08Q. To solve for Q, first do a little algebra, such that .08Q + 4 = 8 or 4 / 0.08 = 50 pies.
c) N = D = 10, 000 = 3.95 orders / year Q 2, 529.8 Tb = T = N 250 3.59 = 63.3 days
= 0.5 * 20 / 415 *( 1- sqrt ( 1- 4.5 * 300 * 10^6 / 300 * 607^2*20)
d. If one gallon of paint will cover 57,600 square inches, how many gallons would be needed to give two coats of paint to 25,000 boards? Round your answer to the nearest gallon.
Q.1 Compute the following quantities for the current production process as well as for Mike’s and Ike’s plans, assuming the plans are implemented as described in the case. (50 points)
A west-bound ship was sighted 1 mile south of a lighthouse. After 15 minutes its bearing was 670 3’ W. How fast was the ship sailing? (Draw the figure).
AP 1.1 To solve this problem we use a product of ratios to change units from dollars/year to dollars/millisecond. We begin by expressing $10 billion in scientific notation: $100 billion = $100 × 109 Now we determine the number of milliseconds in one year, again using a product of ratios: 1 year 1 hour 1 min 1 sec 1 year 1 day · · · = · 31.5576 × 109 ms 365.25 days 24 hours 60 mins 60 secs 1000 ms Now we can convert from dollars/year to dollars/millisecond, again with a product of ratios: 1 year 100 $100 × 109 · = = $3.17/ms 1 year 31.5576 × 109 ms 31.5576 AP 1.2 First, we recognize that 1 ns = 10−9 s. The question then asks how far a signal will travel in 10−9 s if it is traveling at 80% of the
