Answer:
It will take 2.6 s for the ball to hit the ground.
Step-by-step explanation:
This is a standard physics problem
The equation that defines the movement of Ryans baseball is given by the initial velocity, and the acceleration
Distance = Do + Vo*t + 0.5*a*t^2
Where
Do is the initial distance.
(Do = 2m over the ground)
Vo is the initial velocity = 12m/s
a is the acceleration that is exerted on the body (in this case a = g = -9.8 m/s^2 )
t is the time
We substitute in the equation, and solve for t (time)
(0)= 2+ (12)*t + 0.5*(-9.8)*t^2
We get that
t = 2.606 s = 2.6 s
Answer:
C
Step-by-step explanation:
the cosine of an angle = 
, hence
cos 30° = 
→ C
Answer:
slope=1/2
the given point=(0, 13/2)
Step-by-step explanation:
change the equation to the y=mx+b format
y-8=1/2(x-3)
y=1/2x-3/2+8
y=1/2x+13/2
m=slope
1/2=slope
given point(y-intercept)= the constant
given point=13/2
Answer:
The base of the logarithm becomes the base of the exponent. The value that the logarithm is set equal to becomes the the power of exponent. The value you are taking the logarithm of is what you set your exponent equal to.
log

becomes
x=4 (32)
Step-by-step explanation:
Answer: 11/12
Step-by-step explanation:
First find the LCM of 4 and 3(12). Then make the denominator of both fractions 12(3/12 and 8/12). Then add the fractions to get that they ate 11/2 of the lasagna.
