## 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

## Use a calculator to find the approximate value of sin-1 (0.549)

Answered by answersmine AT 22/10/2019 – 03:33 AM This is the concept of algebra, we are required to approximate the arcsin of the value given using a calculator;sin theta=[opposite]/[hypotenuse]arcsin is the inverse of sin, thus;arcsin(0.549)=33.2984the answer is 33.3984°

## 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 …
