Answer:
2 hours
Step-by-step explanation:
6 divided by 3 is 2
Im pretty sure this is correct :)
Answer:
a.
Period = π
Amplitude = 4
b.
Maximum at: x = 0, π and 2π
Minimum at: x = π/2 and 3π/2
Zeros at: x = π/4, 3π/4, 5π/4 and 7π/4
Step-by-step explanation:
Part a:
Amplitude represents the half of the distance between the maximum point and the minimum point of the function. So the easy way to find the amplitude is: Find the difference between maximum and minimum value of the function and divide the difference by 2.
So, amplitude will be:
Therefore, the amplitude of the function is 4.
Period is the time in which the function completes its one cycle. From the graph we can see that cosine started at 0 and completed its cycle at π. After π the same value starts to repeat. So the period of the given cosine function is π.
Part b:
From the graph we can see that the maximum values occur at the following points: x = 0, π and 2π
The scale on x-axis between 0 and π is divided into 4 squares, so each square represents π/4
Therefore, the minimum value occurs at x = π/2 and 3π/2
Zeros occur where the graph crosses the x-axis. So the zeros occur at the following points: π/4, 3π/4, 5π/4 and 7π/4
Answer: 1 / 5 of the total distance.
Step-by-step explanation:
They traveled 7/10 of the distance on Saturday. This means that on Saturday, the fraction left was:
= 1 - 7/10
= 3/10 of the distance
On Sunday, they traveled 2/3 of this remaining distance. The fraction of the distance traveled is therefore:
= 2/3 * 3/10
= 6 / 30
= 1 / 5 of the total distance.
2/3 of 480 is 480 divided by 3 and that number times 2, which is 320. The man or woman probably used $60 of this to buy the tea set, which leaves them with $260.
Answer:
Step-by-step explanation:
here you go mate
step 1
x-6 = 5(x + 2) equation/Question
step 2
x-6 = 5(x + 2) simplify
x+(-)6=5x+10
x-6=5x+10
step 3
x-6=5x+10 subtract 5x
-4x-6=10
step 4
-4x-6=10 add 6
-4x=16
step 5
answer
x=-4
