Answer:
Sally's method
Step-by-step explanation:
Something squared is a number times itself. The square root is the reverse. Michael's method is wronh because he is dividing by 2 (multiplying by½), which is not how you find the square root.
Answer:
180 deg clockwise
Step-by-step explanation:
clockwise is down to the right, up to the left (like a real clock)
the rotation is 180 deg because the shape is now facing the exact opposite way it was at the beginning ( 180 deg is half a circle, so if you face one way and turn yourself half a rotation from your starting position, you have turned 180 degrees)
Hope this helps :)
1) Nashville = center = (-58, 55) => Xc = - 58miles, Yc = 55miles
2) radius = 8 miles
3) General equation of a circle: (x - Xc)^2 + (y - Yc)^2 = radius^2
4) equation of the circle that represents radar coveraga:
(x - (-58) )^2 + (y - 55)^2 = 80^2
=> (x + 58)^2 + (y - 55)^2 = 6400
Answer: (x + 58)^2 + (y - 55)^2 = 6400
3xy multiplied by the cube root of y^2
10! = 10 * 9 * 8* 7 *6 *5 *4 *3 *2 *1 = 3628800
5! = 5*4*3*2*1 = 120
2! = 2*1 = 2
5! x 2! = 120 * 2 = 240
10! / 5!2! = 362880 / 240 = 15,120
