Y=-9x+10 is the equation solved for y.
Answer:
Option C. 0≤x≤25
Step-by-step explanation:
we know that
The function f(x) of the graph is a vertical parabola open down
If the function is at least 300
then
The solution is the shaded area above the solid line f(x)=300
In the graph plot f(x)=300 and find the value of x
The values of x are
see the attached figure
therefore
The interval is ------> [0,25]
All real numbers greater than or equal to zero and less than or equal to 25
A. total power usage PS4 in a week = 8.8 watts x 21 hrs/day x 7 days/week
= (1293.6 watt.hr/week) / (1 kW/1000w)
= 1.29 KW hr/ week
b. carbon emission = 2.1lb/KW
= 1.29 KW x 2.1lb/KW
= 2.71 lb
Just work backwards.
342.5/ 34.25 = 10
So we first need to find a number of cups leaking in a week. Which is simple just multiply 1.5 by 7
1.5 x 7 = 10.5.
Now we convert by knowing how many cups are in a gallon. Since there are 16 cups in a gallon we divide 16 by our total.
16/10.5 = about 1.5
So the amount of gallons leaked per week is 1.5
