Answer:
76.8 inches
Step-by-step explanation:
we have :
1m= 39.37 inches
1.95m =?
we can write:
(1.95m*39.37 inches)/1m=
76.77 inches = 76.8 inches
so finally we have:
1.95m = 76.8 inches
Roots: - √5 , √5, and - 3
=> these are factors of the polynomial: (x + √5), (x - √5), and (x + 3).
Multiply those three factors:
(x + √5) (x - √5) ( x + 3) = [x^2 - 5] ( x + 3 ) = x^2 + 3x^2 - 5x - 15
Therefore the polynomial x^2 + 3x^2 - 5x - 15 is a polynomial with the given roots.
Answer: option B. x^3 + 3x^2 - 5x - 15
Answer:
<em>Last option </em>
Step-by-step explanation:
The general sine function has the following form
Where A is the amplitude: half the vertical distance between the highest peak and the lowest peak of the wave.
is the period: time it takes the wave to complete a cycle.
k is the vertical displacement.
phase shift
We know that:
amplitude: 1; period: 2; phase shift: 3; vertical shift: 4
Thus:
Then the function is:
The answer is last option
