Answer:
compare with the equation of the circle (x-a)^2 + (y -b )^2 = r^2
(a,b) are the centers of the circle
therefore, the centers are (5,4)
Step-by-step explanation:
D
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
with centre = (5, 4) → D
you will only move 15 units up
since the y is the only one that has a value, then you will have to focus more on the direction where the y will go. and since the y's value is positive then you will have to go upwards.
4^3 · 4-^6
= 4^(3 + (-6))
= 4^-3
Answer
A) 4^-3
B
16 + 16 + 16 = 16 x 3
16 x 3 = 48
16 + 16 = 32
32 + 16 = 48
y = 45 when x = 3
