Combine like terms, isolate the variable, and make the slope of the variable 1 to find all the answers.
Answer:
f(x) = 0.25(5.25)ˣ
Step-by-step explanation:
In order to show exponential growth, the numbers must be positive and the base of the exponent must be larger than 1.
Think of it as a percentage. The base of the exponent will be the percentage of the original amount taken each time; if it is less than 1.00 then it would shrink. Larger than 1.00 will grow. The only one with positive numbers and a growth factor of greater than 1 is f(x) = 0.25(5.25)ˣ.
Answer:
A basic formula, solving for x, guides us in the setting up of an equation: D/H x Q = x, or Desired dose (amount) = ordered Dose amount/amount on Hand x Quantity
Step-by-step explanation:
Medications are available in multiple concentrations, therefore orders written in "mL" rather than "mg" are not acceptable and require further clarification.
...
Example 2.
Step 1. Calculate the dose in mg: 18 kg × 100 mg/kg/day = 1800 mg/day
Step 2. Divide the dose by the frequency: 1800 mg/day ÷ 1 (daily) = 1800 mg/dose
Answer:
x + y = 104
0.05x + 0.25y = 22
x = 20 niquels and y = 84 quarters
Step-by-step explanation:
Each niquel is $0.05, and each quarter is $0.25
So if we have x niquels and y quarters, we can set this system of equations:
x + y = 104 (eq1)
0.05x + 0.25y = 22 (eq2)
If we multiply the second equation by 4, and then subtract it from the first equation, we have:
(eq2)*4: 0.2x + y = 88
(eq1) - 4*(eq2): 0.8x = 16
x = 20
Now finding y with the first equation:
20 + y = 104
y = 84
