The correct answer is option D. The coordinates of the centre for the given equation of a circle is (5,4).
The complete question is as below:-
Which of the following points represents the centre of a circle whose
equation is (X - 5)2 + (y-4)2 = 25?
A. (-5,-4)
B. (5,-4)
C. (-5,4)
D. (5,4)
<h3>What is a circle?</h3>
The circle is defined as the locus of the point traces around a fixed point called the centre and is equidistant from the out trace.
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r the radius
(x - 5)² + (y - 4)² = 25 ← is in standard form
We can see that the centre of the circle is (5,4) by comparing the equation with the standard form.
Therefore the correct answer is option D. The coordinates of the centre for the given equation of a circle is (5,4).

Step-by-step explanation:
Answer:
34.22 liters
Step-by-step explanation:
Step one:
Given data
A car averages 28.5 miles per gallon of gasoline
How many liters of gasoline will be needed for a trip of 415 km
let us convert 415km to miles first
1 km is 0.621371 miles
415km is x miles
cross multiply we have
x= 415*0.621371
x=257.86 miles
Step two:
if 1 gallon of gasoline will cover 28.5 miles
the x gallons will cover 257.86 miles
cross multiply we have
28.5x= 257.86
divide both sides by 28.5
x= 257.86/28.5
x=9.04 gallons
Step three:
let us convert gallons to liters
1 gallon is 3.78541 liters
9.04 gallons will be x liters
cross multiply we have
x=9.04*3.78541
x= 34.22 liters
