<em><u>The equation to the rate of increase of the radius in terms of the radius is:</u></em>
<em><u>Solution:</u></em>
<em><u>The rate of increase (R) of the radius (r) in meters per second is inversely proportional to the radius</u></em>
Therefore,
<em><u>The radius is increasing at 1400 meters per second when the radius is 10 meters</u></em>
r = 10 m
R = 1400 meter per second
<em><u>Substitute in eqn 1</u></em>
<em><u>Substitute k = 14000 in eqn 1</u></em>
Thus the equation is found
Answer:
10 / 26
Step-by-step explanation:
cos <Z = adjacent / hypotenuse
= YZ / XZ
= 10 / 26
Answer:
132 feet
Step-by-step explanation:
we know that
The scale is equal to 
That means ---> 1 inch in the model represent 12 feet in the actual
To find the actual dimensions of the airplane, divide the dimensions of the model by the scale
so
Answer:
If the slopes are different, there is one solution.
If the slopes the same but the y intercepts different, there is no solution.
If the slopes and y intercepts are the same, there are infinitely many solutions.
2x + y = 4
2y = 6 - 2x
Solve for y on both
y = 4 - 2x
y = 3 - x
They are both different, so there is one solution
Step-by-step explanation:
5km = 5000 meters
450m+800m= 1250m
5000m-1250m= 3,750m
3 3/4 km
