Answer: C
Step-by-step explanation: 1/3 probability
Answer:
Yes, 1:3.
Step-by-step explanation:
Each of the numbers on figure 2 are 3 times the number on figure 1.
(4xy-2y^2)+2y
4-2=2....x will remain y^1-y^2=y^-1
2xy^-1+2y
answer=2x+2y
Answer:
y = -12
Step-by-step explanation:
You first calculate the x coordinate using the equation x = 
, which in this case is 
.
Then plug that x value into the equation to get the y coordinate:
4(-1)²+8(-1)-8 = -12
Answer:
<u>Option A. about 1 seconds</u>
Step-by-step explanation:
Let the initial speed u and the final speed v
Time t , distance s and acceleration of gravity g
The equation of motion are:
v = u + gt ⇒(1)
s = ut + 0.5 gt² ⇒(2)
v² = u² + 2gs ⇒(3)
Marques drops a plate from a height of 5 feet.
So, u = 0 , s = 5 ft , g = 9.8 m/sec²
Substitute at (2)
s = ut + 0.5 gt²
5 = 0 * t + 0.5 * 10 * t²
∴ t² = 5/(0.5*9.8) = 1.02
∴ t = √1.02 = 1.01 seconds ≈ 1 seconds (to the nearest integer)
<u>The answer is option A. about 1 seconds</u>
