Given: f(x) = −2(x − 4)2 + 2 ; g(x) = 5x2 − 10x + 7 ; no h(x)
Axis of symmetry identification:f(x) = 4 with the formula x=h g(x) = 1 with the formula y=ax^2+bx+c h(x) = -2 with he formula well idk what formula, but the X in the given graph is the axis of symmetry. Think bout it, AXIS of symmetry, the X.
The volume of the gallon is 6000 gallon
the rate of water flow per min is f(t)=300t^2
a] amount of water that flowed in the first 7 minutes=7/60 hours will be:
f(7)=300(7/60)^2
solving the above we get
f(7)=7/12 gallons
b] The time taken for the tank to be empty will be as follows:
amount of water that will flow out for the tank to be empty will be 6000 gallons
thus,
6000=300t^2
this can be simplified to
20=t^2
t^2-20=0
solving this we get:
t=-2√5 or 2√5
the time taken for the tank to be empty will be t=2√5 hours=5.4721 hours
Answer:
B
Step-by-step explanation:
Graph it on desmos and look at where y=4. x value falls in between 1 and 2 (around 1.6)
The left 8 represents 8000 units.
The right 8 represents 8 units.
Their placement in the number is used to signify the multiplier for the number of units they represent. That is why the number system is called a "place value number system." Each time the digit is moved left one place, its value increases by a factor of 10.
Answer:
A and C
Step-by-step explanation:
The volume of a cylinder is the area of a circle times the height.
h
A = Plugging things in we'd have 
12. Which is pi x 64 x 12. Which is pi x 768. Which is 768 pi.
Basically use the same method for the other two questions
