Answer:

Step-by-step explanation:

A. -4

B. 4

C. no values

Step-by-step explanation:

When x increases by 2, m(x) increases by 1.  So m(x) is linear.  Pick two points to find the slope:

(3 − 2) / (10 − 8) = ½

Use point-slope form to write the equation:

m(x) − 2 = ½ (x − 8)

m(x) − 2 = ½ x − 4

m(x) = ½ x − 2

Part A

h(4) − m(16) = ½ (4 − 2)² − (½ (16) − 2)

h(4) − m(16) = 2 − 6

h(4) − m(16) = -4

Part B

h(0) − m(0) = ½ (0 − 2)² − (½ (0) − 2)

h(0) − m(0) = 2 − (-2)

h(0) − m(0) = 4

Part C

m(x) − h(x)

(½ x − 2) − ½ (x − 2)²

½ x − 2 − ½ (x² − 4x + 4)

½ x − 2 − ½ x² + 2x − 2

-½ x² + 2½ x − 4

Complete the square.

-½ (x² − 5x) − 4

-½ (x² − 5x + 25/4) − 4 + ½ (25/4)

-½ (x − 5/2)² − 7/8

This is always negative, so m(x) is always less than h(x).

Which is the more reasonable measurement of the distance between the tracks on a railroad: 1.435 ⋅ 10−3 mm or 1.435 ⋅ 103 mm? Ju
SVEN [57.7K]
The best answer is 1.435 ·103 because while they both are really small for a rail road track that one is bigger. the final answer for that is 147.805mm.

Which is greater, 0.28 or 0.205? Explain how you know.
LuckyWell [14K]

Answer:

Step-by-step explanation:

0.28 is roughly the same as 0.280, which has 3 significant digits (same as 0.205 has 3 significant digits).  It's easier when we compare numbers having the same number of decimal places.

Comparing 0.280 to 0.205, we see that the hundredths place of 0.280 (which is 8) is greater than the hundredths place of 0.205 (which is 0).  Thus 0.28 is greateer than 0.205.

What two numbers add to 10 and multiply to -192? How do you find it?
Levart [38]
There is a way to do this algebraically using equations, but it is really messy so I am going to go over the way to do it. The way you do this is by finding whole numbers that multiply to make -192. Start with 1 and 192, 2 and 96, 3 and 64, etc and make the smaller number negative. 
The reason why you make the smaller number negative is because we are looking for what numbers add together to make a positive number (10). If the bigger number was negative, then we would get a negative sum. 
From what i could find, there aren't any whole numbers that satisfy this, and i doubt that the question would want you to find decimals for this. 

The way to find this with equations (in short) is to have to variables, x and y, and make two equations. in this case x+y=10 and xy=-192. Solve one equation for a variable and then use substitution to plug that variable into the other equation. if you do this you get really long decimals.

how many liters is 70% alcohol solution must be added to 50 L of 40% alcohol solution to produce a 50% alcohol solution
Anettt [7]

Answer:

50%

Step-by-step explanation:

This question is solved by C1V1 + C2V2 ÷ V1 + V2 = final concentration

Let x = volume of 70% solution

 

let's express the concentrations as decimals, so 70% = 0.7, 50% = 0.5, and 40% = 0.4

 

then 0.7X + 50L.4 ÷ X + 50L = 0.5

 

this equation becomes 0.5(X + 50) = 0.7X + 20

which yields 0.5X + 25 = 0.7X +20

combining, we get 5 = 0.2X, and 25 = X

 

when we mix the two volumes, we get 50L x 40% + 25L x 70%,

which yields 20L of 100% alcohol, and 17.5L of 100% alcohol, for a total of 37.5L of alcohol in 75L of solution

 

which is a final concentration of 50%
