1 answer:
Montano1993 [528]3 years ago
5 0

a) 0, 4, 8, 12, 16

explanation- simply add 4 to the previous number. 0+4= 4, 4+4= 8, 8+4= 12, etc etc.

b) 0, 8, 16, 24, 32

explanation- the same as letter a.

c) if you multiply the top number (the x value) by two, then you will get the bottom number (the y value)

explanation- 0+0= 0, 4+4= 8, 8+8= 16, 12+12= 24, and 16+16= 32

d) (0,0), (4,8), (8,16), (12,24), and (16,32)

explanation- the first number comes from the set in letter a (the x value) and the second number comes from the set in letter b (the y value).

e) -

explanation- find a spare piece of graph paper and put the points down. for example, (4,8) would be four places to the right on the horizontal line (the x-axis), and then down 8 places, still staying in the four postion. so four over, eight down. the vertical line is called the y-axis.

Hope this will help somewhat :)

Answer:  

 

1.     What is the period and the amplitude of the sine function representing the position of the band members as they begin to play?

Answer:  Amplitude is 80 ft, period is 60 ft.

 

2.     Edna is sitting in the stands and is facing Darla. Edna observes that sine curve begins by increasing at the far left of the field. What is the equation of the sine function representing the position of band members as they begin to play?

Answer:  y = 80cos(x*π/30)+80

 

3.     As the band begins to play, band members move away from the edges, and the curve reverses so that the function begins at the far left by decreasing. Darla does not move. The sine curve is now half as tall as it was originally. What is the equation of the sine curve representing the position of the band members after these changes?

Answer: y = 40cos(x*π/30)+80

 

4.     Next, the entire band moves closer to the edge of the football field so that the sine curve is in the lower half of the football field from Edna’s vantage point. What is the equation of the sine curve representing the position of the band members after these changes?

Answer:  y = 40cos(x*π/30)+40

Armando and Bianca are 290 feet apart when they start walking toward one another. Bianca walks twice as fast as
aivan3 [116]

9514 1404 393

Answer:

  d = 290 -3x

Step-by-step explanation:

For each x feet that Armondo travels toward Bianca, Bianca travels 2x feet toward Armondo. The net effect is that the distance between them decreases by x+2x = 3x feet. The distance starts at 290 feet when x=0, so the distance can be described by ...

  d = 290 -3x

Does this graph show a function explain how you know
galina1969 [7]
No, the graph fails the vertical line test. In a function, each x value only has one y value. The y value can have more than one x value in a function

Javier drove 45 miles. This represent 60% of his entire trip. What is the total number of miles in Javier’s trip
Andrews [41]
60% of trip = 45 miles

let total trip distance = l

60% is given by multiplying by 0.6

So;

0.6l = 45 \\ \\ l = \frac{45}{0.6} \\ \\ \boxed{l = 75}

Your answer is 75 miles

Let A = R−{0}, the set of all nonzero real numbers, and consider the following relations on A × A. Decide in each case whether R
andre [41]

Answer:

Step-by-step explanation:

Let A = R−{0}, the set of all nonzero real numbers, and consider the following relations on A × A.

Given that (a,b) R (c,d) if ad=bc

Or (a,b) R (c,d) if determinant

\left[\begin{array}{ccc}a&b\\c&d\end{array}\right] =0

a) Reflexive:

We have (a,b) R (a,b) because ab-ab =0 Hence reflexive

b) Symmetric

(a,b) R (c,d) gives ad-bc =0

Or da-cb =0 or cb-da =0 Hence (c,d) R(a,b). Hence symmetric
