Answer:
The data we have is:
The acceleration is 3.2 m/s^2 for 14 seconds
Initial velocity = 5.1 m/s
initial position = 0m
Then:
A(t) = 3.2m/s^2
To have the velocity, we integrate over time, and the constant of integration will be equal to the initial velocity.
V(t) = (3.2m/s^2)*t + 5.1 m/s
To have the position equation, we integrate again over time, and now the constant of integration will be the initial position (that is zero)
P(t) = (1/2)*(3.2 m/s^2)*t^2 + 5.1m/s*t
Now, the final position refers to the position when the car stops accelerating, this is at t = 14s.
P(14s) = (1/2)*(3.2 m/s^2)*(14s)^2 + 5.1m/s*14s = 385m
So the final position is 385 meters ahead the initial position.
Tan(A) = opposite / adjacent
if we call opposite "a" and adjacent "b"
tan(A) = a/b
then...
tan(B) = b/a
because it's on the other angle so "b" is now opposite angle B and "a" is adjacent.
So really you just need to take the reciprocal of the given values.
6. tan(A) = 1.25
reciprocal is flipping the value and using it to divide by 1.
you can keep as decimal , 1/1.25 = 0.8
or change to fraction
1.25 = 5/4
tan(B) = 4/5 or 0.8
7. tan(B) = 0.5
1/0.5 = 2
tan(A) = 2
8. tan(B) = 1
tan(A) = 1
Answer: False
Step-by-step explanation:
False, the value of cosine at pi and 2pi is equal to -1 and 1 respectively. You can test this by using the pi circle or a calculator. Let pi = 180 degrees. Cosine is always defined and alternates between 1 and -1.
Answer:
5.34
Step-by-step explanation:
X + 12.66 = 18
-12.66 -12.66
X = 5.34
I think it's 34.5 (I need more letters so I'm typing this)
