Answer:
One possible solution is 5 + i√3.
(there are 2 solutions 5 + i√3 and 5 - i√3).
Step-by-step explanation:
(x - 5)^2 + 5 = 2
(x - 5)^2 = -3
Take square roots of both sides:
x - 5 = √-3
x - 5 = i√3
x = 5 ± i√3.
The solutions are both complex numbers.
Answer:
D. Infinite solutions
Step-by-step explanation:
Any solution where a number equals itself represents infinite amount of solutions.
1. (-5,-11)
2. C, reflected across x-axis then translated.
3. A’(-1,7), B’(-4,6), C’(-2,2)
4. C’(3,-4)
5. B, rotates 90 counter clockwise and then translate
(if any of these are wrong i’m sorry! :<)
Answer:
The area of the park is calculated through the equation,
A = 0.5ab(cos C)
Substituting the given above,
A = 0.5(533 ft)(525 ft)(cos 53°)
A = 84201.44 ft²
2. We find the radius of the second figure by the equation,
r = C / 2π
Substituting,
r = (30 in) / (2π) = 4.77 in
The radius of the first one is 9 inches. Getting the difference of these two figures will give us an answer of 4.225 inches.

Diameter of the basketball rim = 18 inches
Circumference of the basketball = 30 inches
You would have to fin the area so= pi*r^2
Basketball rim = 3.14 * (18/2)^2 = 3.14 * 9^2 = 3.14 * 81 = 254.34 in^2
The find the Circumference so= 2*pi*r
30 = 2*3.14*r
r = 30 / (2*3.14) = 30 / 6.28 = 4.78 inches
basketball = 3.14 * (4.78)^2 = 3.14 * 22.85 = 71.75 in^2
254.34 - 71.75 = 182.59 in^
The longer leg is the leg adjacent to the larger angle
so 60
length of longer leg = 4 sin60 = 2sqrt(3)
