Answer:
x²-3x=-10
Step-by-step explanation:
x²-3x+0=10
x²-3x=-10
The distance from the center to where the foci is located is 8 units
<h3>How to determine the distance</h3>
The formula associated with the focus of an ellipse is given as;
c² = a² − b²
where;
- c is the distance from the focus to center
- a is the distance from the center to a vertex , major axis is 10 units
- b is the distance from the center to a co-vertex, minor axis is 6 units
Let's use the Pythagorean theorem
Hypotenuse square = opposite square + adjacent square
Substitute the values into the formula
c² = 10² - 6²
Find the square
c² = 100 - 36
c² = 64
Find the square root
c = √64
c = 8
Thus, the distance from the center to where the foci is located is 8 units

Answer:
the number of miles travelled in four hours in the case when she travelled same miles number each hour is 240 miles
Step-by-step explanation:
The computation of the number of miles travelled in four hours in the case when she travelled same miles number each hour is shown below:
= Number of miles × given number of hours
= 60 miles × 4 hours
= 240 mile
Hence, the number of miles travelled in four hours in the case when she travelled same miles number each hour is 240 miles
