Answer:
where −5 ≤ x ≤ 3
Step-by-step explanation:
The given function is
.
We want to select the option that describes all the solutions to the parabola.
The domain of the parabola is −5 ≤ x ≤ 3.
This means that any x=a on −5 ≤ x ≤ 3 that satisfies (a,f(a)), is a solution.
This can be rewritten as 
Therefore for x belonging to −5 ≤ x ≤ 3, all solutions are given by:
where −5 ≤ x ≤ 3.
Answer:
78
Correct term:60
Step-by-step explanation:
We are given that

The quotient of this expression is given by

We have to find the term in this expression which contains an error.

The quotient of this expression is given by


Using the formula

We can see that in the given expression there is 60 in place of 78.
The error in the expression of quotient is 78.
Correct term is 60.
Answer:
perimeter of a square= 4 times square root of area

Answer:10
Step-by-step explanation:
1) Find the mean of the following numbers: 5, 11, 8, 8, 7, 4, 10, 9, 7, 7, 6
SashulF [63]
Mean = 5+11+8+8+7+4+10+9+7+7+6 divided by the number of observations which is 10
Therefore, mean = 73/10
Mean = 7.3
