Answer:
41. <u>(2) x² - 3x - 4 =0</u>
Step-by-step explanation:
<u>Question 41</u>
<u>Standard form of polynomial</u>
- x² - (sum of roots) + product of roots = 0
- <u>(2) x² - 3x - 4 =0</u>
If you have to find x-intercept, then you have to equate y to 0. Thus,
when y=0, x+2·0=5 and x=5.
Point (5,0) is x-intercept.
Answer: (5,0)
Answer: a. 90°
Step-by-step explanation:
We know that the in a circle, the measure of an inscribed angle is half the measure of the central angle with the same intercepted arc.
In the problem∠XYZ is the inscribed angle
∠XYZ=
⇒ ∠XYZ=
Since XZ is a diameter of the circle which is a line segment, thus ∠XZ=180°
∴ ∠XYZ=
∴ ∠XYZ=
Therefore, a. 90° is the measure of ∠XYZ.
