Answer:
the polynomial cannot be factored
Step-by-step explanation:
The ratios of coefficients are 4:3 in the first and second pairs of terms, but the similarity ends there. The second pair of terms has no common factor but 2, and factoring that out leaves nothing in common with the rest of the expression:
= 3x^2(4x -3) +2(4x -3by)
If by=1, this would factor nicely as (3x^2 +2)(4x -3), but that is not the case. The "by" term effectively makes the expression unfactorable.
The expression cannot be factored.
Answer:
the altitude of the helicopter is 3925ft
Step-by-step explanation:
we know the angle that is formed between the floor and the distance from the platform to the helicopter (73°)
and we know the distance of the platform (1200 feet)
at the angle we will call it α
and at the distance of 1200 feet we will call it adjacent
we want to know the height that in this case would be the opposite leg to the angle we have
we see that it has (angle, adjacent, opposite)
well to start we have to know the relationship between angles, legas and the hypotenuse
a: adjacent
o: opposite
h: hypotenuse
sin α = o/h
cos α= a/h
tan α = o/a
it's the tangent
tan α = o/a
we replace the values and solve
tan α = o/a
tan 73 = o/1200
3.2708 * 1200 = o
o = 3925
This means that the altitude of the helicopter is 3925ft
Answer:
Hours of television because it is the explanatory variable.
Step-by-step explanation:
For me, I am assuming the more time spent watching television would cause lower reading scores. I imagine this would be a bar graph, the vertical y-axis would be labeled the reading scores and the horizontal x-axis would be the amount of hours spent watching television. This is because when you graph, you move right then up to get to the unit, meaning the hours of television affect the reading scores. hope this helpss
