Answer:
√128 units
Step-by-step explanation:
As we move to the right from (-4, -2) to (4, 6), x increases by 8 and y increases by 8 also. Using the distance formula, we get:
d = √(8² + 8²) = √(64 + 64) = √128 units (last answer)

Answer:
The function has a maximum of 2 at [tex]x=1[/tex]
Step-by-step explanation:
The graph is a vertical parabola. The minimum, or min is when the parabola opens up, the vertex is at the lowest point on the graph. The maximum, or maxis when the parabola opens down, the vertex is the highest point on the graph.
Since it asks for "[tex]x[/tex]", we can tell that it is 1. If you look at the x-axis in the graph at where the point lies, you will find that [tex]x=1[/tex]

Pulling out like terms
3.1 Pull out like factors :
8x2 - 8 = 8 • (x2 - 1)
Trying to factor as a Difference of Squares:
3.2 Factoring: x2 - 1
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 1 is the square of 1
Check : x2 is the square of x1

Theory - Roots of a product
4.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Equations which are never true:
4.2 Solve : 8 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
4.3 Solve : x+1 = 0
Subtract 1 from both sides of the equation :
x = -1
Solving a Single Variable Equation:
4.4 Solve : x-1 = 0
Add 1 to both sides of the equation :
x = 1

A firm’s production function is

where L denotes the size of the workforce. Find the value of MPL in the case when
(a) L = 1 (b) L = 10 (c) L = 100 (d) L = 1000
The value of MPL for the various cases are;
A) MPL = 49.98
B) MPL = 49.8
C) MPL = 48
D) MPL = 30
We are given;
Q = 50L - 0.01L²
Now MPL means marginal product of labor and it is defined as the derivative of Q with respect to L. Thus;
MPL = dQ/dL = 50 - 2(0.01L)
A) When L = 1;
MPL = 50 - 2(0.01 × 1)
MPL = 49.98
B) When L = 10;
MPL = 50 - 2(0.01 × 10)
MPL = 49.8
C) When L = 100
MPL = 50 - 2(0.01 × 100)
MPL = 48
D) When L = 1000
MPL = 50 - 2(0.01 × 1000)
MPL = 30

5. Victoria sells different sizes of homemade candles.
• Small candles cost the least and sell for $5 each.
• Extra-large candles cost the most and sell for $20 each,
Yesterday Victoria sold a total of 4 candles, including 1 small candle and 1 extra-large candle.
Which could be the total amount Victoria earned from selling candles yesterday?
A. $20
B. $25
C. $50
D. $85
Answer:
Hello! Your answer is C. $50!
Step-by-step explanation:
The problem says Victoria sold a TOTAL of 4 candles. 2 of them are given. If you add up a small and XL candle, its 25. So, you have to try to add 25 and a combinations of small and/or XL candles. When you add one small and one XL, you get 50. Since $50 is the only amount listed that is correct, it would be your answer. Hope this helps!
Answer:
i think 25 because
Step-by-step explanation: 4 x 5= 20 and 4 x 20= 80 so 80+ 20 = 100 then 100 divided by 4= 25

Jacob went bowling over the weekend. On Saturday, he bowled at Bowlero, where he
rented shoes for $3.25 and paid $3.75 for each game. On Sunday, he bowled at the
Cowtown Bowling Center, where he rented shoes for $2.50 and paid $4.00 per game. If
he spent the same amount each day, how many games did he bowl? (Let the number of
games played = x.)
Answer:
x= 3
Step-by-step explanation:
Blowlero's cost of shoes + the cost of one game = $7.00. If we add the cost of a game two more times, we get $14.50
At Cowtown Bowling Center, we can do the same thing. The cost of shoes + the cost of a game= $6.50. If we add the cost of a game two more times, we get $14.50.
For Jacob to have spent the same amount each day, he would have had to played three games at both places.

Step-by-step explanation:
The results of a national survey showed that on average, adults sleep 7.3 hours per night. Suppose that the standard deviation is 1.2 hours and that the number of hours of sleep follows a bell-shaped distribution. If needed, round your answers to two decimal digits. If your answer is negative use “minus sign”.
(a) Use the empirical rule to calculate the percentage of individuals who sleep between 4.9 and 9.7 hours per day.
Enter your answer as a percentage.
%
(b) What is the z-value for an adult who sleeps 8 hours per night?
(c) What is the z-value for an adult who sleeps 6 hours per night?
Using the Empirical Rule and z-scores, we have that:
a) 95% of individuals who sleep between 4.9 and 9.7 hours per day.
b) Z = 0.58.
c) Z = -1.08.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.In item 2, both 4.9 and 9.7 are 2.4 hours from the mean, that is, 2 standard deviations, hence 95% of individuals who sleep between 4.9 and 9.7 hours per day.
What is the z-score formula?The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
For this problem, the mean and the standard deviation are given as follows:
[tex]\mu = 7.3, \sigma = 1.2[/tex]
The z-score for an adult who sleeps 8 hours per night is:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (8 - 7.3)/1.2
Z = 0.58.
The z-score for an adult who sleeps 6 hours per night is:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (6 - 7.3)/1.2
Z = -1.08.
