Answer:
i think the answer is either c or d, but since the 7 is negative, i'd try c first.
Step-by-step explanation:
tell me if this is wrong.
Answer:
13.6 ft
Step-by-step explanation:
The geometric sequence of arc lengths can be described by ...
f(n) = a·b^n
We have (n, f(n)) = (3, 20) and (7, 12). Using these values, we can find the common ratio (b):
20 = a·b^3
12 = a·b^7
Then ...
12/20 = (a·b^7)/(a·b^3) = b^4 = 3/5
We want the 6th term, which we can get from the 7th term by multiplying by b^-1.
b^(-1) = (b^4)^(-1/4) = (3/5)^(-1/4) = √(√(5/3)) ≈ 1.13622
Then the 6th swing had an arc length of ...
f(6) = f(7)·b^-1
f(6) = (12 ft)(1.13622) ≈ 13.63 ft ≈ 13.6 ft
Answer:
93.75 feet and 187.5 feet
Step-by-step explanation:
Let the width of the rectangular area be x feet and the length be y feet. A farmer with 750 feet of fencing wants to enclose a rectangular area and then divide it into three pens with fencing parallel to one side of the rectangle. So, there will be 4 widths and 2 lengths, thus
Find the area:
Find the derivative:
Equate it to 0:
Answer:
f(0) = -3
x increases by 1 f(x) increase by 2
f(x) = 2x -3
Step-by-step explanation:
Looking at the graph
f(0) means when x =0 the value of y = ?
when x = 0 y = -3
f(1) means when x = 1 y = ?
When x = 1 y = -1
y increased from -3 to -1 so it increased by 2
f(x) = ax+b where a is the increase and b is the value at x =0
f(x) = 2x -3
