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 for #1
Let the old price be
$
x
per liter. 10 liters would have cost a total of
$
10
x
.
The new price is
$
(
x
+
0.20
)
per liter. 10 liters would have cost
$
10
(
x
+
0.20
)
.
The total cost is
$
9.20
. So,
10
x
+
10
(
x

0.36
per liter.
Answer: You multiply 1.5 each time.
Step-by-step explanation:
72*1.5=108
108*1.5=162
162*1.5=243

Answer:
B
Step-by-step explanation:
SAS criterion for congruence proves that two triangles are congruent based on their corresponding parts. Since each of the statements before B states parts of these triangles are congruent. B then states that these two triangles are congruent.
