Answer:

  x = 5

Step-by-step explanation:

The table and a graph of f(x) and g(x) are shown in the attachment. The solution is x=5. The table shows you f(5) = g(5) = 2, as does the graph.

It is generally convenient to make use of a graphing calculator or spreadsheet when repeated evaluation of a function is required.

HELP I REALLY NEED SLMEONER TO DO THIS IS HAVE NO IDEA HOW, please do all and show work or as many questions as u can. WILL MARK

It looks like you are good up to problem 4 so I will start there. I believe this is practice worksheet featuring the pyth. theorem. The pyth. theorem is used to find the length of sides in a right triangle notable the hypotenuse (side opposite of 90 degree angle).

4. The monitor is a rectangle but that does not stop you from constructing a right triangle. The smaller lengths are 16 in and 12 in respectively. The hypotenuse of the triangle is the diagonal of the rectangle. To find the length use the pyth. theorem.

diagonal^2 = 16^2+12^2

diagonal = 20 in

7. You know the speeds of both trains and the time spend traveling. You know they are traveling at a 90 degree angle so you can use pyth. theorem. But wait... you need to find the distances traveled for both trains. You can find that though because speed x time = distance.

50mph x 3hrs = 150mi

40mph x 3hrs = 120mi

The distance between the trains after 3 hours is the hypotenuse which can be determined by pyth. theorem.

distance^2 = 150^2+120^2

distance = 192 mi approx.

8. First find length of one piece of wiring. Use pyth theorem. Actually 3,4,5 pyth. triplet in which 5 is the hypotenuse. So you have 5 ft for the length of one piece of wiring. How many pieces of wiring do you need? Well, each tree needs 3 pieces and there are 6 trees so you need 18 pieces.

18 x 5 = 90 ft of wiring

From the work I see, you have a great understanding of the pyth. theorem. Keep it up!

Answer:

It would take 24 hours for Max to steal all the gifts himself

Step-by-step explanation:

The together rate is the sum of each separate rate.

In this problem:

Together rate: 1/8

Grinch's rate: 1/12

Max: 1/x

So

\frac{1}{8} = \frac{1}{12} + \frac{1}{x}

\frac{1}{8} = \frac{x + 12}{12x}

12x = 8(x + 12)

12x = 8x + 96

4x = 96

x = \frac{96}{4}

x = 24

It would take 24 hours for Max to steal all the gifts himself

The function f(h)=8.5h+320 models the amount of money Amy has in her savings after each hour of work.
Ksenya-84 [330]

Answer:

a) h: Number of hours

b) Slope of function

c) y-intercept

Step-by-step explanation:

We are given the following in the question:

f(h)=8.5h+320

The above function tells us about amount of money Amy has in her savings after each hour of work.

a) value of "h"

The above function tells us about the money saved by Amy after each hour of work.

Thus, h here stands foe the number of hours.

b)  meaning of the coefficient h

Comparing the given function to a linear function:

f(h) = mh + c

Thus, coefficient of h is the slope of the function and tells the change in amount of money saved by Amy per unit hour or it tells the change in amount of money when there is a unit increase in hour.

c) meaning of constant

The constant is the y-intercept and tells the amount of money saved by Amy after she have worked for zero hours.
