Zero product states : if a * b = 0, then a = 0 and/or b = 0
(x - 3)(x + 6) = 0
x - 3 = 0
x = 3
x + 6 = 0
x = -6
so x = 3 and x = -6
Answer:
Step-by-step explanation:
From the coordinate geometry, equation of line that passes through two coordinates will be
y-y1 ={(y2-y1)/x2-x1)}(x-x2) where x1=3,y1= -2, x2 =6, y2 = 3. therefore substitute for the values
y-(-2) ={ 3-(-2)/6-3} x (x-6)
y+2 = 3+2/3 x (x-6)
y+2 =5/3(x-6) multiply both side by 3,
3(y+2) = 5(x-6)
3y+6 =5x-30
3y = 5x -30 -6
3y = 5x - 36. Therefore the equation of the line is
3y = 5x - 36.
Y = 68°
Corresponding angles between parallel lines are equal
x and y form a linear pair.
x + y = 180°
68 + x= 180
x= 112°
Its like a polynomial.
cosx=x
so it'll be like
2x^2+3x-2=0
<span>(2x−1)(x+2)

which makes your life easy because you do not have to solve cos(x)=−2 because it cannot be, so only solve cos(x)=1/2
The question is an illustration of probability, and the value of P(B|C) is P(B|C) = 9/24 =0.38
<h3>How to determine the probability P(B|C)?</h3>
The table is given as:
C D Total
A 15 21 36
B 9 25 34
Total 24 46 70
The probability (BIC) is calculated using:
P(B|C) = n(B and C)/n(C)
From the table, we have:
n(B and C) = 9
n(C) = 24
So, the equation becomes
P(B|C) = 9/24
Evaluate
P(B|C) = 0.38
Hence, the value of P(B|C) is P(B|C) = 9/24 =0.38
