Acceleration = change in velocity/ time
Change in velocity= 4– 8 = — 4
A = -4/2
Acceleration is —2m/s^2
Or just -2
General equation for a circle
(x - a)² + (y - b)² = r²
with (a,b) represents the center, (x,y) represents one of the points lie on the circle, and r represents the radius
Determine r² by substituting the points into the general equation
(x - a)² + (y - b)² = r²
(5 - (-1))² + (-4 - 2)² = r²
(5 + 1)² + (-6)² = r²
6² + 36 = r²
36 + 36 = r²
72 = r²
Determine the equation of the circle
(x - a)² + (y - b)² = r²
(x - (-1))² + (y - 2)² = 72
(x + 1)² + (y - 2)² = 72 (This is the equation of the circle)
Answer:
Step-by-step explanation:
Hyp = √(3² + √34²) = √43
cosR = adj/hyp = 3/√43
45.90*0.05=2.295. The answer is $2.30 when you round it off.
Well first, you gotta change all of them into pennies so it would be easier. 342 pennies = 342 pennies, 62 nickels = 310 pennies, and 12 dimes = 120 pennies. Then you add them up: 342 + 310 + 120 = 772. You move the decimal two places to the left. 772 = 7.72. The answer will be 7 dollars, 72 cents remain.
