Answer:
one student = 0.25
3.75 ÷ 0.25 = 15
15 students were tested by the teacher.
Step-by-step explanation:
Answer:
w = -7, -6
Step-by-step explanation:
Solve the equation by factoring:
(w+7)(w+6) = 0
Set each parenthesis equal to zero, and solve for w:
w = -7, -6
Hope this helps!

You just need to substitute x with 1/2
Your answer will then be 3(1/2) which is 3/2 or 1.5
Answer:
The fifth degree Taylor polynomial of g(x) is increasing around x=-1
Step-by-step explanation:
Yes, you can do the derivative of the fifth degree Taylor polynomial, but notice that its derivative evaluated at x =-1 will give zero for all its terms except for the one of first order, so the calculation becomes simple:

and when you do its derivative:
1) the constant term renders zero,
2) the following term (term of order 1, the linear term) renders:
since the derivative of (x+1) is one,
3) all other terms will keep at least one factor (x+1) in their derivative, and this evaluated at x = -1 will render zero
Therefore, the only term that would give you something different from zero once evaluated at x = -1 is the derivative of that linear term. and that only non-zero term is:
as per the information given. Therefore, the function has derivative larger than zero, then it is increasing in the vicinity of x = -1
4t ^ 2 - 16 ÷8 ÷ t - 2 ÷6
=(4t ^ 2)-(16 ÷8 ÷ t)-(2 ÷6)
=(4t ^ 2)-(2/t)-1/3
=4t ^ 2-2/t-1/3
