<em>If wrapping paper costs $0.03 a yard and Anne bought 46.1 yards, how much did Anne spend on wrapping paper. Round your answer to the nearest cent.</em>

<em />

We know that wrapping paper costs $0.03 a yard and that Anne bought 46.1 yards. We want to find out how much Anne spent on wrapping paper so we need to multiply the number of yards, 46.1 by the price per yard which is $0.03.

Now, we begin multiplying as if we were multiplying 461 x 3 to get 1,383. Next, since our original numbers have 3 digits to the right of the decimal point, our answer will have 3 digits to the right of the decimal point. So we have 1.383.

Finally, rounding our answer to the nearest cent, we have $1.38. So Anne spent approximately $1.38 on wrapping paper.

3x^2+kx=-3 What is the value of K will result in exactly one solution to the equation?
Scorpion4ik [409]

Answer:

For k = 6 or k = -6, the equation will have exactly one solution.

Step-by-step explanation:

Given a second order polynomial expressed by the following equation:

ax^{2} + bx + c, a\neq0.

This polynomial has roots x_{1}, x_{2} such that ax^{2} + bx + c = (x - x_{1})*(x - x_{2}), given by the following formulas:

x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}

x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}

\bigtriangleup = b^{2} - 4ac

If \bigtriangleup = 0, the equation has only one solution.

In this problem, we have that:

3x^{2} + kx + 3 = 0

So

a = 3, b = k, c = 3

\bigtriangleup = b^{2} - 4ac

\bigtriangleup = k^{2} - 4*3*3

\bigtriangleup = k^{2} - 36

We will only have one solution if \bigtriangleup = 0. So

\bigtriangleup = 0

k^{2} - 36 = 0

k^{2} = 36

k = \pm \sqrt{36}

k = \pm 6

For k = 6 or k = -6, the equation will have exactly one solution.
