Step-by-step explanation:

For a quadratic equation to have no real roots, the discriminant b² - 4ac must be negative.

For px² + 8x + 2 = 0,

We have a = p, b = 8 and c = 2.

=> (8)² - 4(p)(2) < 0

=> 64 - 8p < 0

=> 8p > 64

=> p > 8

Hence the range for p is p > 8.

Answer:

Eric, 9.8 meters.

Step-by-step explanation:

Use the distance formula with the given coordinate and each of the other coordinate.

$\sqrt{(10-3)^{2}+(8-2)^{2} }$ Brooke

$\sqrt{(-6-3)^{2}+(6-2)^{2} }$ Eric

$\sqrt{(8-3)^{2}+(-6-2)^{2} }$ Cam

You'll see that Eric kicked the furthest distance with a distance of 9.8 meters.

Brooke kicked 9.2 meters and Cam kicked 9.4 meters. What does the distance formula really mean? When you solve for the distance between two points, you're really just creating a triangle between those two points, and you're actually looking for the hypotenuse. The slope that intersects your two points is the hypotenuse of the triangle you created.

The measure of angle sqr is 65 the measure of angle pqs is x what is the vaule of x

Damm [24]

Answer:

Step-by-step explanation:

The value of a right angle is 90° and <SQR is a fraction of <PQR.

Hence, <PQS, which is the other fraction of <PQR, equals 90-50 and 90-50 is 40.

Or we can do it like this;

⇒ 180-90-50

⇒ 90 - 50

⇒ 40

Thus, Answer is 40.
