Answer:
Step-by-step explanation:
<u>Given trinomial</u>
Let's try to factor 4t² - 9t + 2
<u>First find it's zeros:</u>
- t = (9 ± √9² - 4*4*2)/(2*4)
- t = (9 ± √81 - 32)/8
- t = (9 ± 7)/8
- t = 2 and t = 1/4
<u>So yes, it is factorable:</u>
- 4t² - 9t + 2 = 4(t - 2)(t - 1/4)
- or
- 4t² - 9t + 2 = (t - 2)(4t - 1)
<u>The given trinomial factored:</u>
Answer:
1/10
Step-by-step explanation:
In the third quadrant, the tangent is positive.
tan(θ) = tan(arcsin(0.7660)) ≈ 1.1916
Answer:
Great job!
Step-by-step explanation:
A right triangle contains a right angle, so it must have two sides that are perpendicular. If the slopes of two sides can be shown to be negative reciprocals of each other, then it can be concluded that a right angle is formed. If a triangle contains a right angle, then it is a right triangle.
