Answer:
The slope of -3.824 means that if we increase engine size by 1 unit, the mpg will decrease by 3.824 units
Explanation:
mpg=36.91−3.824•Engine size
Writing as y=mx+c then
mpg=−3.824•Engine size+36.91
Where mpy represent y, -3.824 represent m, engine size represent x and 36.91 represent c
Since from the equation y=mx+c m is the slope and c is the y-intercept, therefore,
The slope of -3.824 means that if we increase engine size by 1 unit, the mpg will decrease by 3.824 units
Explanation:
from math import pi//imports the pi constant
def surf_area_sphere(rad)://naming the function and designating input argument
return 4*pi*rad**2//value to be returned
print("Enter a number: ")
rad = float(input())//collects user input
print(surf_area_sphere(rad))//calls the function
Answer:
8.5 days
Explanation:
Given data :
Flow ( Q ) = 2.6 MGD = 11819.834 m^3/day
BOD = 131 mg/L
BOD loading rate = 35 Ibs/1000 ft^3 per day = 0.5606 kg/m^3/day
<u>Calculate the sludge age of the facility </u>
Given the BOD applied to the aeration tank = 11819.834 m^3/day * 131mg/l
= 1548.398 kg/day
first calculate the volume of the aeration tank
V = BOD applied / BOD loading rate
V = 1548.398 / 0.5606 = 2762.03 m^3
Hydraulic Detention time = V / Q
= 2762.03 / 11819.834 = 0.2336 day = 5.6 hour
next : determine the mass rate of the waste
= 44% * 0.5606 kg/m^3/day
= 0.2466 kg/m^2/day
finally determine the sludge age
= V * Xt / ∅w * R
= ( 2762.03 m^3 * 2100 * 10^-3 ) / ( 0.2466 * 2762.03 kg/day )
= 8.5 days
Answer:
• it charges banks more interest
• it sells more securities
• it decreases the money supply
In response to high inflation, the Fed charges banks more interests and pays the banks less interests. It also sells not securities.
