Answer:
2 or 12
Step-by-step explanation:
The answer that we will use this equation 1/t1 +1/t2=1/ttotal
where t1 is the time of smaller pipe while t2 is the of the larger pipe
Given t total =4 while t2 is equal to t2=t1-6
So know you can solve the problem by changing it into (2t1-6)/(t1*(t1-6))=1/4
8( t1-3)=(t1^2-6t1)
t1^2-14t1+24=0
t1=2 or 12
Answer:
Option D.
Step-by-step explanation:
It is given that triangle XYZ has vertices X(–1, –3), Y(0, 0), and Z(1, –3).
Malik rotated the triangle 90° clockwise about the origin. So, rule of rotation is
Now,
The image points are X’(–3, 1), Y’(0, 0), Z’(–3, –1).
Therefore, the correct option is D.
Pretty sure it’s d(all of the above)
Answer:
- 8 or A
Step-by-step explanation:
Problem 1
First of all, you could write f(x) in terms of its x intercepts.
x = - 2
x + 2 = 0
x= 1
x - 1 = 0
x = 4
x - 4 = 0
So f(x) = (x - 4)(x - 1)(x + 2)
The division to find the remainder can be done expanding this further and doing a synthetic division on it, but the easier way is just to put 2 in for x. That is because x - 2 is turned into 0 by making x = 2
f(2) = (2 - 4)(2 - 1)(2 + 2)
f(2) = (-2)(1)(4)
f(2) = - 8
=====================
The expanded form of this question is f(x) = x^3 - 3x^2 - 6x + 8
You could do this with synthetic division. It will give you the same answer.
2 || 1 -3 -6 8
2 -2 -16
=========================
1 -1 -8 -8
The remainder is -8
Answer: A
which gives you exactly the same answer. (x - 2) into x^3 - x^2 - 16x + 16 will leave a remainder of - 12
