Answer:
Circumference of a circle= 
Step-by-step explanation:
The circumference of any circle is the total length of its boundary which can be calculated by the formula:
Circumference of a circle=
Where 'r' is the radius of the circle
For, the given circle the circumference can be find in terms of 
by putting some value of radius in the formula, which gives the circumference in terms of .
Answer:
9000 ft
Step-by-step explanation:
Given: A airplane is ascending at a constant rate of 15 feet per second,
What we need to know: The change in altitude during 10 minutes of flight,
60 seconds = 1 minute
60 × 10
= 600 seconds
600 × 15
= 9000 ft
Therefore there was a 9000 ft change in altitude during the 10 minutes of the flight.
Rationalizing is just simpllifying, so the simplified value has the same value as the original expression.
Answer:
(4, 9) does not satisfy the equation
Step-by-step explanation:
Given the linear equation, y = x - 5, and the point, (4, 9):
We can determine whether (4, 9) is a solution to y = x - 5 by substituting their values into the equation.
x = 4, and y = 9:
y = x - 5
9 = 4 - 5
9 = -1 (False statement)
As demonstrated in our calculations, it turns out that (4, 9) does not satisfy the equation. Therefore, (4, 9) is <u><em>not</em></u> a solution to y = x - 5.
