<h3>
Answer: Choice 2) sin(B) = cos(90-B)</h3>
Explanation:
The rule is that
sin(A) = cos(B)
if and only if A+B = 90.
Solving for A gets A = 90-B
So we end up with
sin(90-B) = cos(B)
which is the same as
cos(B) = sin(90-B)
Let the ratio be 4x,3xand x
Then
According to question 4x+3x+x=64
Or,8x=64
Or,x=8.
Substitute the value of x
4x=32
3x=24
X=8
Both the heads and tails will have a probability of 0.5 with a fair coin. ... TO find probability that foe the 7th toss head appears exactly 4 times.
Answer:
time = distance / speed
time = (5 1/5) / (8 2/3)
time = (26/5) / (26/3)
= 26/5 * 3/26
= 3/5 of an hr <===
Step-by-step explanation:
Answer:
3600 N forward
Step-by-step explanation:
Use Newton's second law.
F = ma
F = 1200 kg × 3.0 m/s²
F = 3600 N
