What is the value of 8P4?
Answers
P(n,r) ; nPr = n!/(n-r)!
8P4 = 8!/(8-4)! = 40,320 / 4! = 40,320 / 24 = 1,680
The value of 8P4 is 1,680

sin(x) = opposite side / hypotenuse
If the opposite side measures 2 ---- [this is the y-component, except for the sign]
hypotenuse measures 5, and the adyacent side is √(5^2 - 2^2) = √(25 - 4) = √21 ---- [this is the x-component, except for the sign].
To assign the sign, we know that the quadrant between pi radians and 3Pi/2 radians is the third quadrant, where both the x-component and the y-component are negative.
Then the point is (-√21,-2). This is option A.
Answer:
(-√21,-2). option A.

Answer:
y = -x - 1
Step-by-step explanation:
Slope - Intercept form is y = mx + b
m = slope
b = y-intercept
We already have the slope of -1. Substitute it into the equation.
y = -x + b
To find b, substitute the given point (2, -3) into the equation.
-3 = -2 + b
b = -1
Substitute the value of b into the equation and you are left with:
y = -x - 1
Answer:
y = -1x - 3
Step-by-step explanation:
y = mx + b
m = slope = -1
b = y-intercept = -3
Plug in
y = -1x - 3

What is a fraction?
A fraction represents a part of a number or any number of equal parts. There is a fraction, containing numerator(upper value) and denominator(lower value).
Therefore, first convert the denominator (bottom n umber) to the same number.
1/2 and 2/3 then the numbers are 2 and 3
the least common multiple is 6
To convert is multiply each by bottom number of the other over the other;
1/2 +2/3
1/2 x 3/3 + 2/3 x 2/2
3/6 + 4/6
(7)/6
7/6
Hence, the simplification of the fraction would be; 7/6.
