I am Lyosha [343]3 years ago
8 0

Answer:

x ≈ - 1.56

x ≈ 2.56

Step-by-step explanation:

x^2 - x = 4

x^2 - x + 1/4 = 17/4

( x - 1/2 )^2 = 17/4

x - 1/2 =Sqrt[17]/2 or x - 1/2 = - (Sqrt[17]/2)

x = 1/2 + Sqrt[17]/2 or x = 1/2 - (Sqrt[17]/2)

The formula - b +- srt(b^2 - 4ac) / 2a could also be used

Let p represent any number in the interval (- 18,22). Rewrite the possible values for p in inequality notation.
Nataliya [291]

Answer:

-18 < p < 22

Step-by-step explanation:

We are given the following information in the question.

The open interval: (- 18,22).

Let p belong to the given interval then p represents all the values belonging to the given interval.

Open Interval: An open interval is a interval that does not include the end points.

Thus, we can write:

-18 < p < 22

is the required inequality form required.

That is p can take values greater than -18 and smaller than 22.

This figure shows circle O with inscribed ∠XYZ. m∠XYZ=76∘ What is the measure of XYZ?
Cloud [144]

Answer:

152

Step-by-step explanation:

Since the measure of angle XYZ is 76 degrees, we know that the measure of XYZ would be twice the amount of the angle measurement due to the square root theorem.  In this case 76 times 2 or 76 plus 76 equals 152 degrees.  152 degrees is your final answer.
