Answer:
From Plato
30e-0.12t less than or equal to M
40e-0.18t less than or equal to M
Step-by-step explanation:
It is given that compound A decays at a rate of 12% per week, and compound B decays at a rate of 18% per week. Since the rates represent decay, the r-value is negative. A decay rate of 12% is represented by an r-value of -0.12, and a decay rate of 18% is represented by an r-value of -0.18.
The initial amount of compound A is 30 grams and the initial amount of compound B is 40 grams. Substitute the initial amounts of each compound and their respective decay rates into the system of inequalities.
The following system of inequalities can be used to determine when the remaining mass of the two compounds, M, will be the same, after t weeks.
If you wanted a numerator of 48, the answer would be 48/104. But if you wanted an answer with 48 as the DENOMINATOR, the answer would be 18/48. Idk when you say "a fraction", but you're looking for a fraction with 48 as BOTH the numerator AND the denominator? That will be equal to 1, so idk if this is the answer you're looking for, but this is how I understood it STILL HOPE IT HELPS THO!
Answer:
459
Step-by-step explanation:
If we break up the figure inot two parts, a rectangle and triangle, we can solve for the area. The area of the rectangle is 396 because the formula for a rectangle is LxW. The area for a triangle is 1/2BxH. So the area of the triangle would be 63. Add these up together and we get 459 centimeters squared.
5.5 quarts
(Divide the volume value by 2)
Answer:
Last one: 3x²
Step-by-step explanation:
Quadratics are functions with the power of 2 as the highest.
Option 1 is a Reciprocal function
Option 2 is a linear function
Option 3 is a exponential function
Option 4 is a quadratic function
