Factor using the difference of squares.
a^2-b^2 = (a+b)(a-b)
100n^2-1
(10n+1)(10n-1)
Final answer: (10n+1)(10n-1)
Answer:
a.
b.
Step-by-step explanation:
a. The equation of a polynomial can be written using its graph by finding the x-intercepts.
The graph has x-intercepts -4, 0, and 3. The x-intercepts are the solutions from the factors of the equation. -4 resulted from x+4. 0 resulted from x except at 0 it doesn't cross through. It touches meaning it has an even exponent likely . And 3 resulted from x-3. Putting these factors together is the equation in factored form.
b. If the function is shifted 2 units to the left then the x-intercepts become -6, -2, and 1. So the factors are .
Answer:
Area of a circle = 3.14 X radius X radius
= 3.14 X 4.5 X 4.5 = 63.585 m2

Start by drawing a right triangle with legs matching the given point.
Horizontal leg = -8, Vertical leg = 3
The hypotenuse should be identical to a line going from given point to origin.
Next, use pythagorean theorem to find length of hypotenuse.
= sqrt((-8)^2 + 3^2) = sqrt(64+9) = sqrt(73)
Finally use trig ratios for cos, csc, and tan. (csc = 1/sin)
SOH --> sin = opp/hyp = 3/sqrt(73)
csc = 1/sin = sqrt(73)/3
CAH---> cos = adj/hyp = -8/sqrt(73) = (-8*sqrt(73))/73
TOA ---> tan = opp/adj = -3/8
