The weight, w, of a spring in pounds is given by 0.9 times the square root of the energy, E, stored by the spring in joules. If the energy stored by the spring is 12 joules, what is the approximate weight of the spring in pounds?

Answered by answersmine AT 22/10/2019 – 02:34 AM The is the concept of algebra, the weight of the spring can be modeled by the equation;w=0.9sqrt Ewhere;=energy in joules;thus the weight of the spring when the energy is 12 j will be:w=0.9sqrt12w=3.18 g

Look at the graph of this system of equations: y = – x2 + 1 and y = x2. At which approximate points are the two equations equal? A) (-0.7, 0.5) B) (0.5, 0.7) C) (0.7, 0.5) D) (-0.5, 0.7) Note: There can be more than answer. Help me and I will give you brainliest. Thank you. In this picture, there’s the graph.

Y=-x^2+1 and y=x^2 When the two curves intersect their coordinates will be equal, so we can say y=y whenever a solution exists, so: x^2=-x^2+1  add x^2 to both sides 2x^2=1  divide both sides by 2 x^2=1/2  take the square root of both sides x=±√(1/2), so there are two solutions, we …

In 1987 the first substance to act as a superconductor at a temperature above that of liquid nitrogen (77 k) was discovered. the approximate formula of this substance is yba2cu3o7. calculate the percent composition by mass of this material.

  The molar mass of the elements are: Yttrium (Y) = 88.91 g / mol Barium (Ba) = 137.33 g / mol Copper (Cu) = 63.55 g / mol Oxygen (O) = 16 g / mol   Calculating for the molar mass of YBa2Cu3O7: YBa2Cu3O7 = 88.91 + 2(137.33) + …

A circle fits in a square with sides of 12 inches. What is the approximate area of the shaded region between the square and the circle? (Use 3.14 for pi and round to the nearest whole number.)

You need to determine the number of ways in which 30 competitors from 50 can qualify. First, you have to realize that the order is irrelevant, that is: it is the same competitor_1, competitor _2, competitor _3 than competitor_3, competitor_2, competitor_1, or any combination of those three competitors. So, the …
