We can take out x as a factor
What is 7-1=?
6 !
So then that means
So your final answer is
Answer:
5
Step-by-step explanation:
The leading coefficient belongs to the term with the largest exponent
Given
5
- 7x³ + 2x + 1 ← in standard form
The leading term is 5 ← with leading coefficient 5
3 + 5(9+2n)
Distribute the 5 to the items in the parentheses
3 + 5(9+2n)
3 + 45 + 10n
Combine like terms
48 + 10n
Answer:
The value of the sample mean resonance frequency is 112Hz
Step-by-step explanation:
A confidence interval has two bounds, a lower bound and an upper bound.
A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.
In this problem, we have that:
Lower bound: 111.6
Upper bound: 112.4
Sample mean: (111.6 + 112.4)/2 = 112Hz
The value of the sample mean resonance frequency is 112Hz
Solution = m(x)=-(x-7)^2+49
