Answer:
a) -3
b) 5
c) 7
d) 4
Step-by-step explanation:
We have the function
a) We need to find the coefficient of .
This means that we need to find out what number is alongside the in this equation. From the function, we can find that it is -3
b) Now we need to find the degree of . Recall that the degree refers to the highest power of x that is present. As
is the largest power, our degree would be 5.
c) The constant term refers to the number within the function that does not have any x's with it. In this function, that number would be 7.
d) Now we need to find the number of terms. For this one, we just need to count how many terms are separated by + or - signs. There are 4 in this function.
Answer:
4.5 cm.
Step-by-step explanation:
We have been given that circle O has a circumference of approximately 28.3 cm.
We will use circumference formula to solve for the radius of our given circle.
Upon substituting the measure of circumference in above formula we will get,
Therefore, the radius of circle O is 4.5 cm.
