Answer:
Yeah rectangle should be the answer
Answer:
2
Step-by-step explanation:
f(x) = 2x - 3 is a linear function
The rate of change of a linear function is the measure of the slope.
The equation is in slope- intercept form, that is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x - 3 has slope m = 2
Thus rate of change = 2

Answer:
16.07 milligrams
Step-by-step explanation:
From the question,
Using the formula of radioactive decay,
R/R' = 2ᵃ/ᵇ..................... Equation 1
Where R = Original mass of the polonium-210, R' = Final mass of polonium-210 after decaying, a = Total disintegration time, b = half life of polonium-210.
Make R' the subject of the equation
R' = R/(2ᵃ/ᵇ)................ Equation 2
Given: R = 100 milligrams, a = 1 years = 365 days, b = 138.39 days
Substitute these values into equation 2
R' = 100/(2³⁶⁵⁰⁰/¹³⁸³⁹)
R' = 100/(6.222)
R' = 16.07 milligrams of plonium-210
