Step-by-step explanation:
Without solving the equation, determine the nature of the roots of x2 - 2 x - 8 = 0.
The equation x² - 2x - 8 = 0 has two real and distinct roots.
Explanation:A quadratic equation is an equation of the form ax² + bx + c = 0. In this equation, the coefficient of the x² term is 1, so a = 1, b = -2, and c = -8. We can determine the nature of the roots without solving the equation by looking at the discriminant, which is the term inside the square root of the quadratic formula. The discriminant is given by b² - 4ac. If the discriminant is positive, the equation has two real and distinct roots. If the discriminant is zero, the equation has two real and identical roots. If the discriminant is negative, the equation has two complex roots.
In this case, we have b = -2 and a = 1, so the discriminant is (-2)² - 4(1)(-8) = 4 + 32 = 36. Since the discriminant is positive, the equation has two real and distinct roots.
Prove the Converse of the Pythagorean Theorem using similar triangles. The Converse of the Pythagorean Theorem states that when the sum of the squares of the lengths of the legs of the triangle equals the squared length of the hypotenuse, the triangle is a right triangle. Be sure to create and name the appropriate geometric figures.
Answer:
To prove the Converse of Pythagorean Theorem:
Step-by-step explanation:
1. Draw a right triangle (Triangle ABC)
2. Draw an altitude from and A to the hypotenuse creating 2 new triangles
3. The part that intersects the hypotenuse will be point D, this makes a right angle
Triangle DBA and triangle ABC both have right angles and share angle B, this means that triangle ABC and triangle DBA are congruent by the AA postulate. Since triangle DAC and triangle ABC both have right angles(angle D and angle A) and they share angle C, triangle DAC and ABC are congruent by the AA postulate as well.
The ratios can be set up as:
AC/BC = DC/AC & AB/BC = DB/BA
Once cross multiplied, the result should be:
(AC)² = (BC)(DC) & (AB)² = (BC)(DB)
Now add both sides together to get:
(AC)² + (AB)² = BC(DC) + (BC)(DB)
To make things easier, factor out the like terms:
(AC)² + (AB)² = BC(DC + DB)
When looking at the triangle(must draw to see), it shows that (DC + DB) is actually side BC. This leaves:
(AC)² + (AB)² = BC(BC) → (AC)² + (AB)² = (BC)²
The Pythagorean theorem says that a² + b² = c². Knowing this, on the original triangle, side AB = a, side AC = b, and side BC = c. Knowing this:
(AC)² + (AB)² = (BC)² → a² + b² = c²
This proves the Converse of the Pythagorean Theorem.

The diagram shows triangle MNP. Which term describes point Q?
Answer:
(B) Incenter
Step-by-step explanation:
From the given figure, it can be seen that PMN is a triangle where MQ is the angle bisector of ∠NMP, PQ is the angle bisector of∠NPM and NQ is the angle bisector of ∠MNP.
Also, It is equally distant from the three line segments forming the sides of the triangle. Thus, By the definition of incenter, Q can be named as the incedntre of the given triangle PMN.
Since, the centroid, circumcenter and orthocenter does not satisfy the conditions given in the figure, thus Q can not be considered as centroid, circumcenter and orthocenter.
Hence, option B is correct.
Answer:
the answer is incenter

You want to embroider a square design. You have an embroidery hoop with a 6 inch diameter. Find the largest value of x so that the entire square will fit in the hoop. Round to the nearest tenth
The largest size of the square that can be embroidered within the 6 inch hoop is 4.2 inches per side (rounded to the nearest tenth). This is found using geometry principles involving squares and circles.
Explanation:This question is asking for the side length of a square that will fit within a circle, or in this case, an embroidery hoop, with a certain diameter. This is a concept from geometry that involves the relationship between squares and circles. Essentially, the diameter of the circle becomes the diagonal of the square.
To calculate the side length (x) of the square, we'll use the formula for the diagonal (d) of a square divided by the square root of 2 (d = √2 * x). Since the diameter of the hoop is 6 inches, rearranging the equation gives us x = d / √2 which results in x = 6 / √2 = 4.2 inches (rounded to the nearest tenth)

So the question says...
Suppose you have ∠SMB and m ∠SMB =125.35 °.
Part A: Determine the angle measure that is complement to ∠SMB, if possible. If ∠SMB does not have a complementary angle, then explain why it does not.
Part B: Determine the angle measure of the supplement of ∠SMB.
Part C: Determine the angle measure of the angle complement to ∠SMB’s supplement.
I’m stuck on this question so if anyone can help me with it that would be greatly appreciated. Thanks!
Part A: ∠SMB does not have a complementary angle
Part B: The angle measure of the supplement of ∠SMB is 54.65°
Part C: The angle measure of the angle complement to ∠SMB's supplement is 35.35°
The given angle is ∠SMB and m ∠SMB =125.35 °
For Part AComplementary angles are angles that sum up to 90°.
To determine the angle measure that is complement to ∠SMB, we will find the angles that adds up to ∠SMB to give 90°. Since ∠SMB is already greater than 90°, therefore, ∠SMB does not have a complementary angle.
For Part B.Supplementary angles are angles that sum up to 180°.
To determine the angle measure of the supplement of ∠SMB, we will find the angle that adds up to ∠SMB to give 180°. Let the measure of the angle be x, that is
x + 125.35° = 180°
∴ x = 180° - 125.35°
x = 54.65°
∴ The angle measure of the supplement of ∠SMB is 54.65°
For Part C
To determine the angle measure of the angle complement to ∠SMB's supplement, we will determine the measure of the angle that adds up to ∠SMB's supplement to give 90°. Let the angle be y
Then,
y + 54.65° = 90°
(NOTE: ∠SMB's supplement is 54.65°)
∴ y = 90° - 54.65°
y = 35.35°
∴ The angle measure of the angle complement to ∠SMB's supplement is 35.35°
Hence,
Part A: ∠SMB does not have a complementary angle
Part B: The angle measure of the supplement of ∠SMB is 54.65°
Part C: The angle measure of the angle complement to ∠SMB's supplement is 35.35°
