What is the value of 2.5 - 14.3 (-18.2)?

Mathematics
1 answer:
julia-pushkina [17]3 years ago
6 0

Answer:

262.76

Step-by-step explanation:

We must follow our order of operations here, which tell us to multiply before we subtract.

-14.3 • (-18.2) = 260.26

Then we can look at what's left:

2.5 + 260.26

Work that out to get your answer, 262.76

1a) f(x) = I x+2 I. This is a piece-wise graph ( V form)
      x = 0 →f(x) =2 (intercept y-axis)
      x = -2→f(x) = 0 (intercept x-axis)
      x = -3→f(x) = 1 (don't forget this is in absolute numbers)
      x = -4→f(x) = 2 (don't forget this is in absolute numbers)
Now you can graph the V graph

1b) Translation: x to shift (-3) units and y remains the same, then
      f(x-3) = I x - 3 + 2 I = I x-1 I
     the V graph will shift one unit to the right, keeping the same y. Proof:
     f(x) = I x-1 I . Intercept x-axis when I x-1 I = 0, so x= 1

<h3>Answer:   200.96 ft^2  (choice C)</h3>

=======================================================

Work Shown:

A = pi*r^2

A = 3.14*8^2

A = 200.96

Note that the radius r = 8 is half of the diameter d = 16. I'm using the approximation pi = 3.14, which means the area is approximate. To get a more accurate answer, use more decimal digits of pi. The units of the area are in square feet, which can be written as "sq ft" or as "ft^2".
