Answer: The expression which must fill in each blank space to complete step 3 is; Choice B; Cos(A)Cos(B).
Which expression must fill in each blank space?
From the task content; It follows that the mathematical evaluation is in a bid to derive the Trigonometric identity for Tan (A-B).
From observation, it follows that the required expression is; cos(A)sin(B). This is because upon division of each term by the expression, the result is as in Step 4.
Given the expression
-2 + 6.45z - 6 + (-3.25z)
First, classify like terms, constant with constant, coefficient-variable with coefficient-variable
-2 + 6.45z - 6 + (-3.25z)
= 6.45z + (-3.25z) - 2 - 6
Second, combining like terms
= 6.45z + (-3.25z) - 2 - 6
= 6.45z - 3.25z - 8
= 3.20z - 8
The simplest form is 3.20 - 8

Answer:
<em>Answer: B San Francisco</em>
Step-by-step explanation:
It can be read that Geneva is 12°C colder than Nikki's hometown. It can be seen in the table that Geneva is at -3°C.
This means that Nikki's hometown is 12°C hotter than Geneva, thus:
Temperature of Nikki's hometown = -3°C + 12°C = 9°C.
The only city with a temperature of 9°C is San Francisco.
Answer: B San Francisco
