Answer:
240
Step-by-step explanation:
The average rate of a function f(x) is interval [a,b] is given by :-
R = (f(b) - f(a)) / (b-a)
Now, the given function : F(x) = 4(5)^x
Interval : [1,3]
Now, the average rate of change over the interval [1, 3] is given by :-
R = F(3) - F(1) / (3 - 1)
= 4(5)^3 - 4(5)^1 / 2
= 4(5^3 - 5) / 2
= (4(125 - 5) / 2) = 240

Answer:
3m² + 7m - 6
Step-by-step explanation:
2m (3/2m + 1) + 3(5/3m - 2)
(3m² + 2m) + (5m - 6)
3m² + 2m + 5m - 6
3m² + 7m - 6
Answer:
1/5
Step-by-step explanation:
For Monday
The fraction of homework Chain completed =
40% of her homework
= 40% = 40/100
= 2/5
For Tuesday
The amount of home work left =
= 1 - 2/5
3/5
The fraction of homework Chain completed on Tuesday = 2/3
= 2/3 Of 3/5
= 2/3 × 3/5
= 2/5
Let the total complete homework be represented by 1
Hence:
The Fractional part of her homework left for her to complete after Tuesday =
1 - (2/5 + 2/5)
Lowest common denominator is 5
= 1 - (2 + 2/5)
= 1 - (4 /5)
= 1/5
Answer:
-1.5
Step-by-step explanation:
4x² + 4x - 3 = 0
(2x + 3)(2x - 1) = 0
2x + 3 = 0 or 2x - 1 = 0
x = -3/2 or x = 1/2
Answer: -1.5
