Period =
The ferris wheel will complete one round in 40 seconds.
Step-by-step explanation:
We are given the function representing the height of the wheel by,
where t = time in minutes.
Now, we know that if a function f(x) has period P, then a×f(bx+c)+d will have the period .
Since, the function has period , thus the function h will have period i.e. .
Therefore, the period of this function is .
Now, since the period is minutes i.e 40 seconds.
Hence, we get that the ferris wheel will complete one round in 40 seconds.
Answer:
20(pi)
Step-by-step explanation:
• equation for the circumference of a circle= 2(pi)r
• You are given the diameter ( 20ft) but you need the radius (r) for the equation.
• divide 20 by 2 to get the radius since it is half of the diameter.
• 20/2=10 so c= 2(pi)(10)
• 2(10)=20
• plug in pi and your final answer is 20(pi)
Answer: B
Step-by-step explanation:
You can see that if you were going to cut the graph down the middle, if would be symmetrical.
answer 5/6 decimal form is 0.83
Answer:
y=5/3x-3
Step-by-step explanation:
first, let's put 3x+5y=15 into y=mx+b form
move 3x to the other side
5y=-3x+15
divide by 5
y=-3/5x+3
now, perendicular lines have slopes that are negative and reciprocal.
With our new equation we can automatically find the slope, which would be 5/3.
now, we need to find b
plug the points (3,2) into y=5/3x+b
2=5/3(3)+b
2=5+b
-3=b
so that means that our equation will now be
y=5/3x-3.
Hope this helps!
