K is constant. if you increase g(x) by x. f(x) also increases by x
Answer:
True
Step-by-step explanation:
So we know that:

And we are asked to verify whether f(2)=0 is true or false.
To determine the answer, substitute 2 for n in the function and solve. So:

Square and multiply:

Subtract:

So, the statement is indeed true.
And we're done!
Answer:
The parts it includes is everything from elementary equation solving to the study of abstractions such as groups, rings, and fields. The more basic parts of algebra are called elementary algebra; the more abstract parts are called abstract algebra or modern algebra. Examples of ways that we use algebra are finding the distance, perimeter of an area, volume, determining the cost of something, renting something, time relationships, pricing options for something you want to buy, and more.
Step-by-step explanation:
Answer:
50 Degrees
Step-by-step explanation:
Since they already have 40 degrees for you, and a little square means a right angle (90 Degrees), then 40 + 90 is 130. The interior angles of a triangle always add up to 180, so 180 - 130 is 50. The answer is therefore 50 degrees.
Answer:
Light is moving at the speed = 77.78 km/min
Step-by-step explanation:
Given:
Distance between island and point P = 5 km
Moving along the the shoreline when it is 1 km from P.
So, x = 1
From the above statement light makes seven revolutions per minute.
Therefore,
Solution:
From the given figure.

Substitute x = 1
-------------------(1)
Now, first we differentiate both side with respect to t.

Using chain rule.



Substitute
from equation 1.


Substitute 

Applying cross multiplication rule.


Therefore, light is moving along the shore at the speed of 77.78 km/min
