Rashid [163]

Step-by-step explanation:

1) Your problem → (4x^2 - 17x^3 + 9) - (x^2 + 9x + 23x^2 + 11)

(-17x^3+4x^2+9)-(x^2+23x^2+9x+11)

=-17x^3+4x^2+9-x^2-23x^2-9x-11

=-17x^3+4x^2-x^2-23x^2-9x+9-11

=-17x^3-20x^2-9x-2

2) Your problem → 0 - 19.73 - 25x^2 - 12x - 3

=0-19.73-25x2-12x-3

=-25x^2-12x-22.73

3) - 10.x^3 – 162x^2 – 24x - 4

4) Your problem → 17x^3 - 20x^2 - 9x^2

=17x^3-20x^2-9x^2

=17x^3-29x^2

5) -16x^3 – 243x^2 – 12x – 3

What is the greatest possible error if irina measured the length of her window as 3.35 feet? 0.5 0.05 0.005 0.0005
AlladinOne [14]

3.35 feet have a maximum inaccuracy of 0.005 feet.

The correct option is C.

<h3>What is error analysis?</h3>

When students consistently commit mistakes, an approach known as error analysis is frequently employed to determine the root of the problem. Reviewing student work is the first step in the process, after which misunderstood patterns are sought out. Mathematics mistakes can be conceptual, procedural, or factual, and they can happen for a variety of reasons.

<h3>Given:</h3>

The window is 3.35 feet long.

Find the biggest error you can

<h3>According to the given data:</h3>

Half of the measuring unit is considered to be the maximum amount of measurement error.

3.35 feet are calculated to the nearest centimeter, or 0.01 feet

Consequently, the largest conceivable error is equal to half of the measurement unit.

= .01/2

= .005

Therefore, the maximum inaccuracy for 3.35 feet is 0.005 feet.

in 2005, the total waste generated in a certain country was 3.474x10^9 pounds. also in 2005, the countrys population was 1.23x10
Serggg [28]

Answer:

2824

Step-by-step explanation:

Take the number of pounds and divide by the number of people:

3.474×10⁹ / 1.23×10⁶

Divide the coefficients and subtract the exponents:

(3.474 / 1.23) × 10⁹⁻⁶

2.824×10³

So the country produced about 2,824 pounds of garbage per person in 2005.
