If both the zeroes of a polynomial x2+4x+2p are real and equal then find the value of p.

Mathematics

Answer:

p = 2

Step-by-step explanation:

If both zeroes at equal, they must be the negative half of the second term. As this term is 4, -\frac{4}{2} =-2. This means that each of the zeroes must be -2. This means that the polynomial must be  (x+2)^2

This simplifies to x^2+4x+4

From the intial problem, we can set up an equation and solve for p. 2p=4\\\\p=2

Alexus [3.1K]

Answer: Approximately 8.49 feet

==================================================

Explanation:

Draw a right triangle. The reference angle is between the ground and the kite string (aka hypotenuse). The hypotenuse is 12 and the side opposite the reference angle is x.

Refer to the diagram below.

We'll use the sine rule to find x

sin(angle) = opposite/hypotenuse

sin(45) = x/12

12*sin(45) = x

x = 12*sin(45)

x = 8.48528137423857

x = 8.49

This value is approximate.

Make sure your calculator is in degree mode.

I rounded to 2 decimal places, but feel free to round however you need if your teacher instructs otherwise.

I NEED HELP ASAP PLEASE, A woodworker makes wooden checkerboards. Her profit is a function of the price
chubhunter [2.5K]

Answer:

Option (C)

Step-by-step explanation:

The given graph represents the relation between her profit and the price charged.

x-intercepts from the graph are at,

x = 20 and x = 65, which show the selling prices.

x-intercepts means y = 0

And y = 0 represents no profit no loss.

When we summarize these data,

zeros : x = 20 and x = 65

These are the selling prices that will give her neither profit nor loss.

Therefore, Option (C) will be the answer.
