Answer:

E = 30.37 J

Step-by-step explanation:

Given that,

The spring constant of the spring, k = 300 N/m

The spring is stretched by 0.45 m, x = 0.45 m

We need to find the elastic energy stored in the spring. The formula for the elastic energy is given by :

E=\dfrac{1}{2}kx^2\\\\=\dfrac{1}{2}\times 300\times (0.45)^2\\\\=30.37\ J

So, the required elastic energy is equal to 30.37 J.

Write an equation for a function that has vertical asymptotes at x=3 & x=-10
stepan [7]

Answer:

\frac{5}{ {x}^{2}   + 7x - 30}

Step-by-step explanation:

We can write a rational function.

We need to make sure our denominator both have zeroes at 3 and 10.

Set an equation equal to zero to find the function

0 - x = 3

0 - x =  - 10

0 - ( - 3) =  = 3

0 - 10 = 10

So we would represent that's as

x - 3

and

x + 10

Multiply the two binomial together.

(x - 3)(x + 10) =  {x}^{2}  + 7x  - 30

Let our numbetator be any interger.

Use any equation as long as the quadratic is the denominator and the interger is the numerator.

\frac{5}{ {x}^{2} + 7x - 30 }

Divide and write in simplest form 4/7 divided by 1 1/7
IrinaVladis [17]

First, change the mixed fraction into improper fraction

1 1/7 = 7/7 + 1/7 = 8/7

(4/7)/(8/7)

To solve, flip the second fraction, and change the division into multiplication

(4/7)/(8/7) = (4/7) x (7/8)

Multiply, and simplify

(4/7) x (7/8) = 28/56, or 1/2

1/2 is your answer

hope this helps
