Answer:
The value of f(-2) is 1/2 or it can be written as 0.5.
Step-by-step explanation:
The given function is
We have to find the value of f(-2).
Substitute x=-2 in the given function to find the value of f(-2).
Therefore the value of f(-2) is 1/2 or it can be written as 0.5.
Answer:
If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is is dA/dt = 15 - 0.005A
Option C) dA/dt = 15 - 0.005A is the correction Answer
Step-by-step explanation:
Given the data in the question;
If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is?
dA/dt = rate in - rate out
first we determine the rate in and rate out;
rate in = 3pound/gallon × 5gallons/min = 15 pound/min
rate out = A pounds/1000gallons × 5gallons/min = 5Ag/1000pounds/min
= 0.005A pounds/min
so we substitute
dA/dt = rate in - rate out
dA/dt = 15 - 0.005A
Therefore, If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is is dA/dt = 15 - 0.005A
Option C) dA/dt = 15 - 0.005A is the correction Answer

Yes u have to and as long are you do than you would be right
60 miles in total.
to find percentages, you divide the part by the whole, so 33/60 = .55, which you then move the decimal over two places and read as a percentage
