<u>Given</u>:
Given that the radius of the circle is √98 units.
The circle is centered at the point (5.9, 6.7)
We need to determine the equation of the circle.
<u>Equation of the circle:</u>
The general form of the equation of the circle is given by
where (h,k) is the center and r is the radius of the circle.
Substituting the center point (h,k) = (5.9, 6.7) and r = √98, we get;
Simplifying, we get;
Thus, the equation of the circle is
Answer:
Step-by-step explanation:
Given:
The equation is given as:
Rearrange the above equation in standard quadratic equation of the form
Adding on both sides, we get
Here,
Now, we solve this using quadratic formula,
Answer:
a) Destiny can run 1 mile is 6 minutes.
b) Destiny can walk back 1 mile is 16 minutes.
Step-by-step explanation:
The running rate of Destiny is
So, she runs 1 mile in
= 6 minutes
Hence, Destiny can run 1 mile is 6 minutes.
The walking rate of Destiny is
So, she walks 1 mile in
= 16 minutes
Hence, Destiny can walk back 1 mile is 16 minutes.
