Answer:
t = 100 - 5n : rule for amount of money left.
You will have $45 left after using downtown parking 11 times.
Explanation:
The equation for an arithmetic sequence in this case is t = a + dn.
a is the initial value, d is the rate of change, and n is the independent variable.
t is the dependent variable.
In this context, a is the starting budget for parking, d is the amount parking costs each time, n is the number of times you use the parking and t is the amount of money left after each time you use the parking.
Substitute the known values from the problem into the equation.
t = a + dn
t = 100 + (-5)n <= the rate of change is -5 because it's decreasing
t = 100 - 5n
To find the amount of money left after 11 times using downtown parking, substitute n for 11.
t = 100 - 5n
t = 100 - 5(11)
t = 100 - 55
t = 45
You will have $45 left after 11 times parking downtown.
Answer: (A), (B), (C) and (E)
Explanation:
- Coral reefs are found in the oceans formed by the accumulation of the skeletal remains of the invertebrates. They are found under water.
- Cold seeps refers to those area where the gases such as methane, hydrogen sulfide comes out through the vent, under water.
- Hydrothermal vents are the places where the hot intruding magma reacts with the sea water producing a vent.
- Rocky intertidal zone refers to the zone between a high and a low tidal mark.
Thus under the ocean, the structures such as coral reefs, cold seeps and hydrothermal vents forms where the tide is not so high and not so low.
Kelp forest is the odd one, that refers to those brown colored seaweeds, having high nutrients in salt water.
Answer:
a volcanic mountain is formed by the oceanic plate going under the continental plate causing the formations of trenches and mountains, the friction caused by the oceanic plate sliding under the continental plate makes enough heat for it to become volcanic.
