ExtremeBDS [4]

Answer:

The second one: r x-axis. R 90(x,y)

Step-by-step explanation:

You can see that from ABC to A'B'C', it's rotated a positive 90 degrees. then, from A'B'C' to A"B"C", reflected across x-axis. and when writing the transformation, it goes by last to first. that's why the R 90 comes first.

please help!!! the study conducted was 6 days long: there was 72mm of plant food and it decreased an equal amount each day.
Anuta_ua [19.1K]

Answer:

f(x) = 72 - 12x

Step-by-step explanation:

No. of days of study = 6

Amount of food to use for the 6 days = 72 mm

Given that equal amount of food was used each day, amount used per day = \frac{72}{6} = 12 mm

This would enable us derive a function for the amount of food remaining f(x), which can be expressed as a function of the number of days that have passed, (x).

Thus, we would have:

f(x) = 72 - 12x

Let's check if this equation expresses the relation of the function well.

At the end of day 1, if we used, 12mm, we would have 72 - 12 = 60mm of food remaining.

If we replace x in the equation we derived, we would get the same 60mm as the amount of food remaining.

If you try 2, 3, 4, 5 days, you'd get same thing.

At the end of the study, after the 6th day, the food would remain nothing.

Replace 6 for x in the relation function derived, you'd get a value of 0.

Problem:
BARSIC [14]

Answer:

(c) Equation  which can be used to find r, the cost in dollars to park s nights is  r = 24.99 s

Step-by-step explanation:

Here, the parking cost of 1 night at the airport  = $24.99

Now, here the total number of nights the car is parked at airport = s

R = The total cost of parking s nights

Now, The cost for parking s nights  = s x ( Cost of parking 1 night)

= s x ($24.99) = 24.99 s

Also the cost for parking s nights    = r

⇒  r = 24.99 s

Hence, equation  which can be used to find r, the cost in dollars to park s nights is  r = 24.99 s
