A quadratic graph. It makes an upside down U shape
<span>The word problem gives a rate of oil consumption at a rate of 25 gallons per 3 hours and 45 minutes. 3 hours and 45 minutes can be displayed as 3.75 hours. so you can say the generator consumes oil at a rate of 25 gallons per 3.75 hours. The following equation give you the oil consumption on a per hour basis; 25/3.75 and that gives you 6.67 gallons per hour. In 6 hours the generator will consume 40 gallons.</span>
Answer:
a) Y = -3x/5 + 15
b) Y = 3 - 0.6x
d) Volume = 15Pi
e) Volume of cone = 15pi
Step-by-step explanation:
The detailed steps and appropriate integration is as shown in the attached file.
The answer would be -2x + 8.
3 - x - (x - 5)
3 - x - x + 5
3 + (-x - x) + 5
3 - 2x + 5
(<u>-2x + 8).</u>
Let x dollars be your investment at 7%;
then the investment at 3% is the rest (1000-x) dollars.
The total interest equation is
0.07x + 0.03*(1000-x) = 0.061*1000.
Express x and calculate
x = %280.061%2A1000-0.03%2A1000%29%2F%280.07-0.03%29 = 775.
ANSWER. $700 is the 7% investment; the rest, (1000-775) = 225 dollars is the 3% investment.
