Answer:
At x= 4 the given expression is undefined.
Step-by-step explanation:
In a given function , if the denominator becomes zero then the function is undefined.
Here, denominator is x-4 so at x = 4 it will become zero. So we can say that at x=4 , the function is undefined
1 hour = 60 minutes.
60 minutes / 20 minutes = 3.
55 people x 3 = 165 people per hour. (Rate per hour)
165 people x 3 hours = 495 people. (Total people in 3 hours)
X = -20p + 500
20p = 500 - x
p = (500 - x)/20
R = xp = x(500 - x)/20 = (500x - x^2)/20
Answer:
Triangle Q R P is shown. The length of Q R is 5 and the length of R P is 6. Angle Q R P is 40 degrees.
Step-by-step explanation:
The trigonometric formula refers the two sides length of the triangle and it also consists of included angle to find out the area
A =
ab sin C
QPR contains two sides and the included angle
XYZ has one side and the two angles
DEF has only three sides
And, the ABC contains two sides but does not have the included angle
Based on the explanation above, the correct option is B
Answer:
Step-by-step explanation:
If x - 1 is a factor of the cubic, then 1 should result in 0 when you put it in the cubic for x. Does it?
f(1) = 2(1)^3 - 15(1)^2 + 22(1) + 15
f(1) = 2 - 15 + 22 + 15
f(1)= 24.
No the result is not zero. So x - 1 is not a factor.
However there must be something that makes this cubic go to zero. The easiest way to find it is to graph it.
The numbers that do make this zero are -0.5, 3, 5
Which mean that the factors are (2x+1)(x-3)(x - 5)
