For what value of k are there two complex solutions to the given quadratic equation (k+1)x²+4kx+2=0.

nlexa [21]

Answer: $k\in \left ( \frac{-1}{2},1\right )$

Step-by-step explanation:

Given

$\left ( k+1\right )x^2+4kx+2=0$

For complex roots Discriminant should be zero

D<0

$D=\sqrt{b^2-4ac}$

here

$D=\sqrt{\left ( 4k\right )^2-4\left ( k+1\right )\left ( 2\right )}$

$D=\sqrt{16k^2-8k-8}$

so $16k^2-8k-8$

$2k^2-k-1$

$\left ( 2k+1\right )\left ( k-1\right )$

so $k\in \left ( \frac{-1}{2},1\right )$

A building company used 24 workers to prepare a building site. The site measured 30 acres and the work was completed in 10 days.

maks197457 [2]

Answer:

30 workers are required.

Step-by-step explanation:

If the site measured 30 acres and was completed in 10 days, then it can be said that on average $\frac{30}{10} = 3\frac{acres}{day}$ were made.

Then, 24 workers completed 3 acres / day.

Then, $\frac{24.workers}{\frac{3acres}{day}} = \frac{8..Workers * days}{acre}$

8 workers can complete 1 acre per day

Now to know how many workers are needed to complete 45 acres in 12 days, we multiply:

$8\frac{Workers * days}{acre}*\frac{45}{12} \frac{acres}{days} = 30.workers$ .

Finally, 30 workers are required.

To solve this problem it was assumed that everyone worked at the same pace, which may not be true, the fact that some work at a slower or faster pace than another could alter the result, causing them to finish less or more acres by day.
