D. because if you plug the X and Y coordinates into the equation. the equation will always be true
Answer:
(x + 2)
Step-by-step explanation:
x² - 8x - 20
consider the factors of the constant term (- 20) which sum to give the coefficient of the x- term (- 8)
the factors are - 10 and + 2 , since
- 10 × + 2 = - 20 and - 10 + 2 = - 8 , then
x² - 8x - 20 = (x - 10)(x + 2)
1.
-2(a + 6) = -2 · a - 2 · 6 = -2a - 12
2.
-22:
whole numbers
rational numbers
integers
3.
6 · (b - p) = 6(b - p)
4.
[5(14 - 2)²]/2 = (5 · 12²)/2 = (5 · 144)/2 = 720/2 = 360
5.
u + xy
u = 18; x = 10; y = 8, subtitute
18 + 10 · 8 = 18 + 80 = 98
6.
A = 479 ft²;
a - length of a side
A = a²
therefore
a² = 479 ⇒ a = √479 ⇒ a ≈ 21.886 ⇒ 22 (ft)
7.
(7 + 5) + 4 · 13 - 2 = 12 + 52 - 2 = 64 - 2 = 62
Trigonometric Identities.
To solve this problem, we need to keep in mind the following:
* The tangent function is negative in the quadrant II
* The cosine (and therefore the secant) function is negative in the quadrant II
* The tangent and the secant of any angle are related by the equation:
We are given:
And θ lies in the quadrant Ii.
Substituting in the identity:
Taking the square root and writing the negative sign for the secant:
Answer:
1/50 times 2/99 = 2/4950
divide numerator and denominator by 2 and the answer you should get is 1/2475 and in decimal form it equals 0.00040404040404040
