Answer:
h(x) = x/2 + 5
Step-by-step explanation:
f(x) = 2x - 10
Step 1. Replace f(x) with y.
y = 2x - 10
Step 2. Switch variables x and y.
x = 2y - 10
Step 3. Solve for y.
2y - 10 = x
2y = x + 10
y = x/2 + 5
Step 4. Replace y with h(x)
h(x) = x/2 + 5
Area of circle = πd²/4, where d = diameter
= π*6*6/4 = 9π ≈ 9 *3.1416 ≈ 28.2744 cm²
Area ≈ 28.27 cm²
Hope this explains it.
Answer:
- The first factor is itself the sum of two terms
- The solution is the product of two factors
Step-by-step explanation:
The math symbols of the expression include parentheses, a plus sign, and a multiplication symbol. The order of operations tells you to do the "plus" operation inside parentheses first. The numbers involved in a "plus" operation, or sum, are called "terms." The result is their sum.
Then the second operation in the order of operations is to do the multiplication of the sum on the left of the multiplication symbol by the number to the right of the multiplication symbol. The numbers involved in multiplication are called "factors". The result of multiplication is called a "product."
Matching up this vocabulary with what you see, you realize ...
- the first factor is the sum of two terms
- the end result of evaluating the expression is the product of two factors
If you take 46.59 and subtract 43.8 you get 2.79. Therefore 2.79 is your answer.
