Answer 1

Answer:

Answer:

Step-by-step explanation:

We can use the "vertical line test" to determine whether a given graph represents a function or not.

If your vertical line intersects the graph in more than one place, the graph does NOT represent a function. Thus, D does not represent a function, as a line drawn vertically thru this graph intersects the graph multiple times.

Graph A: Note that if you draw a vertical line thru x = -2, your line will intersect the BLACK dot (-1 3/4, 0) and the EMPTY circle (-1 3/4, 3 1/4). This is OK; this graph represents a function.

How do you get 34 from P = 5s - (100 + 2s) when P = 0 is s ≈ 33.333.

Answers

P = 5s - (100 + 2s) Carefully remove the brackets. Watch the signs.
P = 5s - 100 - 2s
P = 3s - 100

0 = 3s - 100 Add 100 to both sides.
100 = 3s Divide by 3
100/3 = s

s = 33.33333 It is just a rounding factor. It depends on what you are really finding. So whatever answers you're given (if any), choose the one closest to 33.33333 which is likely what you got when you did it.

P = 5s - (100 + 2s)
when P = 0

0 = 5s - (100 + 2s)
0 = 5s - 100 - 2s
0 = 3s - 100
100 = 3s
s = 100/3
s = 33.3333....

You can't get 34. Whoever told you that is a liar.

Mark has some nickels, dimes, and quarters in his pocket. He has three times as many quarters as nickels. He has five more dimes than nickels. The total amount he has in his pocket is $5. How many of each coin does he have

Answers

15 quarters
10 dimes
5 nickels

five more dimes than nickels means we know there is at least 5 dimes, or 50 cents
if we subtract this from $5, we have $4.50.
With those 5 dimes gone, the number of dimes equals the number of nickels. If there are 3 times as many quarters as nickels, there are also 3 times as many quarters as dimes. So for every 3 quarters (0.75), there is one dime (0.10) and one nickel (0.05).
0.75 + 0.10 + 0.05 = 0.90
you find the number of remaining coins by dividing the total minus the 5 dimes (4.50) by 0.90.
4.50 ÷ 0.90 = 5
this is how many times 3 quarters, one dime, and one nickel go into 4.50
so, the answer to how many of each coin is:
3 quarters × 5 = 15 quarters
one dime × 5 = 5 plus the original 5 we took out = 10 dimes
one nickel × 5 = 5 nickels

to check answer:
5.00 = 15(0.25) + 10(0.10) + 5(0.05)
5.00 = 3.75 + 1.00 + 0.25
5.00 = 5.00 ✔

A bird leaves its nest and travels 14 miles per hour downwind for x hours. On the return trip, the bird travels 4 miles per hour slower and has 6 miles left after x hours.a. What is the distance of the entire trip?

miles

b. How long does the entire trip take? (In Hours Minutes and Seconds

Answers

1.5hr the distance of the entire trip
The time for the entire trip is 3.375 hours.
The total distance of the trip is 60 miles.

The total distance of the trip

The given parameters include;

The speed of the bird in the forward trip = 20 m/h
Time of motion = x
The speed of the bird in the backward trip in x hours = (20 - 4)m/h = 16 mi/h.
Distance remaining to complete the backward trip = 6 miles.

The time to complete each trip is calculated as;

distance = $speed $*$ time$

forward distance = backward distance

$&20 x=16 x+6 \n$

$&20 x-16 x=6 \n$

$&4 x=6 \n$

$&x=(6)/(4) \n$

$&x=1.5 h r$

The total time of the motion for the entire trip exists calculated as follows;

Time = time for forward + time for backward

$\text { time } &=1.5 \mathrm{hr} r_{\text {forward }}+1.5 \mathrm{hr} \text { backward }+\frac{6 \mathrm{mi}}{16 \mathrm{mi} / \mathrm{hr}} \text { backward } \n$
