Answer:
B. 1/2
Step-by-step explanation:
This problem involves the use of the Pythagorean theorem. In the unit circle, the hypotenuse of any right triangle formed is 1 while the coordinates of the point are then the two legs that make up the triangle.
a = 1 (given)
b = √3/2 (given)
a² = b² + c² (Pythagorean Theorem)
1² = (√3/2)² + c² (Substitute information)
Now, we need to solve for c
1 = (3/4) + c² (square the hypotenuse and one of the legs)
1 - (3/4) = (3/4) + c² - (3/4) (subtract 3/4 on both sides)
1/4 = c² (combine like terms)
√(1/4) = √(c²) (square root both sides)
√1 / √4 = c (square root both sides)
1/2 = c (final answer)
Therefore the other leg of the right triangle is 1/2, this also means that the other coordinate, or x, is 1/2, so the answer is B. 1/2.
Step-1 : Multiply the coefficient of the first term by the constant 12×( -35) = -420
Step-2 : Find two factors of -420 whose sum equals the coefficient of the middle term, which is -1 .
-420 + 1 = -419
-210 + 2 = -208
-140 + 3 = -137
-105 + 4 = -101
-84 + 5 = -79
-70 + 6 = -64
-60 + 7 = -53
-42 + 10 = -32
-35 + 12 = -23
. -30 + 14 = -16
-28 + 15 = -13
-21 + 20 = -1
That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -21 and 20
12x2 - 21x + 20x - 35
Step-4 : Add up the first 2 terms, pulling out like factors :
3x × (4x-7). Add up the last 2 terms, pulling out common factors :
5 × (4x-7)
Step-5 : Add up the four terms of step 4 :
(3x+5) × (4x-7).
Which is the desired factorization
Final result : (4x - 7) × (3x + 5)
SO YOUR ANSWER IS D.(4x - 7) • (3x + 5)

<span>When 2 people work the formula is:
Person1 * Person2 / (Person1 + Person2)
</span>
<span>rob becomes Person1 and Kayla becomes Person 2
9 * K / (9 + K) = 4.74 Hours
9*K = 4.74*9 + K*4.74
9*K = 42.66 + K*4.74
4.26 *K = 42.66
K = 10.014084507 hours (Kayla)
TESTING the answer
(9 * 10.014084507) / (9 + 10.014084507) = 4.74
90.126760563 / (19.014084507) = 4.74
4.74 = 4.74

We are given: Barrel quantity averages = 50 pounds.
Crate quantity = 120 pounds.
Number of barrels is taken by variable x and
Number of crates is taken by variable y.
The elevator load should be greater than of total load.
Therefore,
50 * number of barrels + 120 * number of crates > Total load.
50*x +120*y > Total load.
50x +120y > total load.
