Answer:
4
Explanation:
The amplitude of a sine function is the absolute value of the coefficient of sin(in other words, the absolute value of the number multiplying the sin)
In this case, that is |-4|=4
3 < k
Step-by-step explanation:
Simplify by undoing addition to both sides, then divide both sides by the coefficient of k.
Answer:
Step-by-step explanation:
The radius of the circle is 34cm
r=34cm
Circumference of the circle is the same as perimeter of the circle and it is described as
P=2πr
Therefore,
P=2×22/7×34
P=213.714cm
The circumference of the circle is 213.714cm
