Step-by-step explanation:
step 1
Answer:
By an online search, i found that the options are:
Option A. A(10)
Option B. A(11)-A(9)
Option C. A(10)/10
Option D. A’(10)
Let´s start by defining the concept of a derivative.
When we have a function f(x), the derivative, f´(x), is a measure of the rate of change of f(x) with respect to the variable x.
Then if A(t) represents the area covered by the oil, A´(t) is the rate of change of this area as a function of t.
Particularly, A´(10), will be the rate of change at t = 10.
Then the correct option is: Option D. A´(10)
It would be the 2.16 meters one. Because adding a 0 would be 2.160
1. b. Commutative Property of Addition
Reason: There is no multiplication used
2. a. 60
Reason: 36 + 24 = 60
3. b. 3d + 9
Reason: Simplification and combining like terms :)
4. b. 4,-1
Reason: Coefficients are the numbers in front of variables
5. b. 36m + 9
Reason: Just use distributive property (multiply 9 into both terms inside parenthesis)
6. b. 95.488
Reason: b = 165.288 - 39.7 - 30.1
7. The question is cut off, unanswerable
8. c. 5a, -3a
Reason: Like terms are things you can combine. So technically the answers could be b. and c. but just go with c. because they have variables.
9. b. 16
Reason: just add 4 to both sides to get the "a" by itself
Best of luck to you!
Answer:
We are given
We are also given and , which allows us to rewrite the equation as
(I substituted every "b" with "a" and every "c" with "9").
The solutions to this quadratic equation are -25 and 7. We discard -25 because a side with negative length would make no sense.
