Answer:
second option
Step-by-step explanation:
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 is the radius
Here (h, k) = (4, 5) and r = 2 , thus
(x - 4)² + (y - 5)² = 2², that is
(x - 4)² + (y - 5)² = 4 ← equation of circle
Subtracting a value from the exponent shifts the graph to the right.
So if you subtract 3, the graph would shift 3 units to the right.
Answer:
A = s²
Step-by-step explanation:
A = s² where s represents the side lengths
Since the side lengths of a square are always the same, you can use the formula A = s² for a square instead of using A=l(w)
256. Since each side is congruent, the length equals 8. 8 times 8 equals 64. Divide it by 2 to find the area of the triangle. 64 divided by 2 equals 32. Since there are 8 congruent triangles, 32 x 8 equals 256.
Answer: ($3.055, $3.205)
Step-by-step explanation:
Given : Significance level :
