Answer:
392m^2
Step-by-step explanation:
as the length = diameter of the circular park
then
Area = length * width = 56 * 7 = 392m^2
Answer:
Range
Step-by-step explanation:
The range of a graph tells you <u>all of the possible y-values</u> for it.
There is also the domain, which tells you all of the possible x-values.
For example, if you have this relation, that only has these points:
(1, 2) (2, 4) (3, 6)
Then the range is {2, 4, 6}. This means the "y" can ONLY be the numbers stated here.
The domain would be {1, 2, 3}.
Answer:
x = -2
Step-by-step explanation:
The tangent line has length "x + 8"
The secant line has length "x + 6 + 5", where
5 is the inner part
x + 6 is the outer part
Now,
the secant-tangent theorem tells us that square of the tangent line is equal to the outer segment of secant line multiplied by length of whole secant line.
So, we can say:

We can solve for x shown below:

The value of x is -2
Answer:
The ship will be
far from its port 3.5 hours from now
Step-by-step explanation:
Hi
The function is
relates the number of kilometers y the ship will be from its port x hours from now, it has a form
.
As the function is clearly defined, we only have to evaluate it for
, so
is the distance between the cruise ship and its port after 3.5 hours.
V (velocity) = distance / time
So distance = velocity x time = 20 x 10 = 200 ft.
