A cart with an unknown mass is at rest on one side of a track. A student must find the mass of the cart by using newton’s second

law. The student attaches a force probe to the cart and pulls it while keeping the force constant. A motion detector rests on the opposite end of the track to record the acceleration of the cart as it is pulled. The student uses the measured force and acceleration values and determines that the cart’s mass is 0. 4kg. When placed on a balance, the cart’s mass is found to be 0. 5kg. Which of the following could explain the difference in mass?.

Lesson 6 homework practice use the pythagorean theorem answer key
labwork [276]

Pythagorean theorem should be used to determine the length of any of the three sides of a right-angled triangle.

<h3>What is Pythagorean Theorem?</h3>

Pythagorean theorem can be defined as a fundamental mathematical equation in Euclidean geometry and it can be used to determine the length of any of the three (3) sides of a right-angled triangle.

Mathematically, Pythagorean's Theorem is given by this formula:

c² = a² + b²

<u>Where:</u>

  • c is the hypotenuse.
  • a is the adjacent side.
  • b is the opposite side.

<u>For example:</u>

c² = 3² + 4²

c² = 9 + 16

c² = 25

c = √25

c = 5 units.

Which scale factors produce a contraction under a dilation of the original image? select each correct answer. −2 −12 ​12​ ​​2.
vitfil [10]

Answer:

-2 and -12

Explanation:

A dilation is a transformation of a geometric image that is known to change its size not it shape.

The size of the figure basically depends on the scale factor (k).

When k >1 then there would be expansion.

When k <1 then there would be contraction.

When k=1 then no change in size

I.e for conraction the scale factor (k) must be negative

from the given options, the scale factor produce a contraction under a dilation of the original image would be -2 and -12

<h3 /><h3>Hence the correct answers are:-2 and -12 </h3>

Answer:

0.295

Explanation:

Given that:

Total number of modems = 19

Number of defective modem = 3

Non-defective modems = 19 - 3 = 16

Probability of that all selected modems are not defective :

Required outcome / Total possible outcomes

[(16C6) * (3C0)] ÷ 19C6

(8008 * 1) ÷ 27132

8008 / 27132

= 0.2951

Hence,

Probability of accepting the shipment is 0.295
