Answer:
See attachment.
Step-by-step explanation:
The main part of the function is an absolute value function and so it forms a V with the center of the V at (0,0). The sides of the V go up and over 1 unit at a time. However, since 2 is added to the it outside of the absolute value, the center of the V moves from (0,0) to (0,2). The sides stay the same. The division by 2 changes the sides. The sides move from up and over 1 unit to up 1 unit and over two units. It spreads or widens the graph. Lastly, the interval selects a specific part of the graph only from 0 to 6 on the x-axis. This takes just one side of the V and looks like a line segment. See attachment.
We can either convert to standard form first or convert to a common multiplier, kinda like a common denominator. The latter makes more sense if they wanted the result in scientific notation, but let's do it that way anyway.
a)
4.5 × 10⁴ + 3.8 × 10³ = 45 × 10³ + 3.8 × 10³ = 48.8× 10³ = 48,800
Answer: 48,800
b)
4.5 × 10⁴ - 3.8 × 10³ = 45 × 10³ - 3.8 × 10³ = 41.2× 10³ = 41,200
Answer: 41,200
c)
7.2 × 10⁻³ + 6.3 × 10⁻² = 7.2 × 10⁻³ + 63 × 10⁻³ = 70.2 × 10⁻³
= 7.02 × 10⁻² = 0.0702
Answer: 0.0702
<span>The inside diameter of the pipe is calculated by subtracting twice of the wall thickness from the given outside diameter.
In mathematical symbols that would be:
ID = OD - 2T
Substituting the known values,
ID = (5 7/32 inches) - (2)(5/32 inches) = 4.9 inches
Therefore, the answer is 4.9 inches</span>
-3 + [(36/9) - 3] × (-2)
First solve Parenthesis:
* -3 + [4-3] × (-2)
** -3 + (1) x (-2)
Second solve multiplication:
*** -3 + (-2)
Third step, solve addition/substraction:
**** -3-2= -5
So your answer si -5
