Example 3.7.4: The sum of two positive numbers is 16. What is the smallest possible value of the sum of their squares

Answers

Answer:

The smallest possible value of the sum of their squares is 128.

Step-by-step explanation:

Let the first number = x

let the the second number = y

x +  y = 16

y = 16 -x

minimum value, f = x² + y²

f(x) = x² + (16-x)²

f(x) = x² + 256 - 32x + x²

f(x) = 2x² - 32x + 256

f(x)' = 4x - 32

4x - 32 = 0

4x = 32

x = 32 / 4

x = 8

The absolute minimum value of x = 8

y = 16 - x

y = 8

The smallest possible value of the sum of their squares is given by x² + y²;

=  (8)² + (8)²

= 128

Therefore, the smallest possible value of the sum of their squares is 128.

Answers

Answer:

C.3(x + 2) can be rewritten as 3x + 6

Step-by-step explanation:

Given 3(x+2)

Evaluating the expression by opening the parenthesis;

3(x+2) = 3(x) + 3(2) Distributive law

3(x+2) =3x + 6

Hence 3(x+2) is equivalent to 3x+6

Hence the correct answer is C.3(x + 2) can be rewritten as 3x + 6

Now, to find 'x' you will apply the Null Factor Law. This means you will now let 'x' = 0, and simply move the -2 over to the other side to find your answer. Note: since we are using a perfect square, x will only have one value since there is only one answer (x-2) in the brackets, meaning in this case we can ignore the exponent (as the answers will be the same). If there was more than one answer in the bracket (e.g. (x-4) and (x-6)), then we would apply Null Factor Law to both brackets and solve for x.

Which brand should the store eliminate?
O A. Brand B
O B. Brand D
O C. Brand C
O D. Brand A

Answers

Answer: They should eliminate Brand C

Step-by-step explanation:

You need to divide the total returns by the total sold to which Brand has the greatest percentage returned.

The brand that the store should eliminate out of the 4 given brands using the data in the table is; Brand C

How to Solve Percentage Problems?

To find the brand that the store should eliminate we need to find the percentage of sold items that were returned and pick the highest percentage as the brand the store should eliminate.

Brand A percentage = [tex]\frac{33}{685}[/tex] × 100 = 4.81%

Brand B percentage = [tex]\frac{15}{492}[/tex] × 100= 3.04%

Brand C percentage = [tex]\frac{29}{361}[/tex] × 100 = 8.03 %

Brand D percentage = [tex]\frac{31}{766}[/tex] × 100 = 4.04%

Brand C has the highest percentage and as such it is the brand that should be eliminated.

Answer:

List all of the solutions.

50 k m =

9 m i n u t e s =

14 k m =

Step-by-step explanation:

Answer:

y = -4x + 50

Step-by-step explanation:

To write the function we'll use y = mx + b, where y is the distance the boat is away from shore, m is how many km/minute the boat moves at, x is how many minutes it's been, and b is how many km away from shore the boat was at the start. We already know the value of b is 50, so we can put that into the equation:

y = mx + 50

To find how many km the boat moves per minute, let's use the given amount of minutes and km (9, 14) and put them into the equation:

14 = m(9) + 50

Now let's solve for m:

14 = 9m + 50

Subtract 50 from both sides to isolate the 9m:

14 - 50 = 9m + 50 - 50

- 36 = 9m

divide both sides by 9 to isolate the m:

-36/9 = 9m/9

-4 = m

The boat moves at -4 km/minute, which is the same thing as saying that  after 1 minute passes, the boat gets 4km closer to the shore. Now we can input this value into the equation and we have our answer:

y = -4x + 50
