13/100, 40/100, 58/100, 6/10
Answer:
58/100
Step-by-step explanation:
The first step is to make the two fractions have a common denominator. 5/10=50/100. Now you can add the two fractions together. 50/100+8/100=58/100. Hope this helps!
Answer:
The area at time t is given by
Step-by-step explanation:
We know the radius of the oil spill as a function of time, and we know the area as a function of radius, and we want the area at time t. In other words we are looking for area as a function of time
We find by putting into as a substitute to r:
Which is our answer.
To find the composite function for the area of the oil spill over time, replace 'r' in A(r) = πr2 with the function r(t). The function becomes A(t) = π(0.5 + 2t)2.
In order to find the function that represents the area of the oil spill over time, we need to write a composite function. This means we plug the function r(t) into A(r). Since r(t) = 0.5 + 2t, you can replace every instance of 'r' in A(r) = πr2 with (0.5 + 2t) to get the area as a function of time 't'. So, the composite function becomes A(t) = π(0.5 + 2t)2. Now we have a composite function that represents the area of the oil spill, denoted by A(t), as a function of time. The function is: A(t) = π(0.5 + 2t)2.
