The expression cosine of pi over 2 times cosine of pi over 3 plus sine of pi over 2 times sine of pi over 3 can be rewritten as

9966 [12]

Solution:

Given;

$\cos\frac{\pi}{2}\cos\frac{\pi}{3}+\sin\frac{\pi}{2}\sin\frac{\pi}{3}$

Using the identities;

Thus;

$\begin{gathered} \cos\frac{\pi}{2}\cos\frac{\pi}{3}+\sin\frac{\pi}{2}\sin\frac{\pi}{3}=\cos(\frac{\pi}{2}-\frac{\pi}{3}) \\ \\ \cos\frac{\pi}{2}\cos\frac{\pi}{3}+\sin\frac{\pi}{2}\sin\frac{\pi}{3}=\cos(\frac{\pi}{6}) \end{gathered}$

A leak in a water tank causes the water level to decrease by 3.6×10−23.6×10−2 millimeters each second. About how many millimeter

Zolol [24]

Answer: $6.48 \times 10^2$

Step-by-step explanation:

Since, According to the question,

The leak in a water tank causes the water level to decrease by $3.6\times 10^{-2}$ millimeter

That is , in 1 second it decreases $3.6\times 10^{-2}$ mm

⇒ In $1.8\times 10^4$ seconds it will decrease $3.6\times 10^{-2}\times 1.8\times 10^4$ mm

⇒ In $1.8\times 10^4$ seconds it will decrease $6.48\times 10^{2}$ mm

Mr. Johnson has his newspaper delivered every day. He determines the probability the newspaper is on his front porch is 0.64. Th

n200080 [17]

Answer:

Step-by-step explanation:

Probability of getting the newspaper on his front porch = P(A) = 0.64

Probability of finding the newspaper on his lawn = P(B) =? (We don't know, this is what we have to find.)

Total probability = 1

Formula, P(A) + P(B) = 1

Let's put all values in this formula,

0.64 + P(B) = 1

P(B) = 1 - 0.64

P(B) = 0.36

Thus, the probablity that Mr. Johnson finds his newspaper on his lawn is 0.36 or 36%.
