Answer:
- x² - 8x + 12
- x³ + 2x² - 15x - 36
- x³ -2x² - 15x
Step-by-step explanation:
#1) Find the polynomial with roots at 2 and 6
-
(x -2)(x - 6) = x² - 8x + 12
#2) Find the polynomial with a double root at -3 and another root at 4
-
(x+3)(x+3)(x-4) = (x²+6x+9)(x-4) = x³ + 2x² - 15x - 36
#3) Find the polynomial with roots 0, -3 and 5
- (x -0)(x+3)(x-5) = x(x²-2x - 15) = x³ -2x² - 15x
Answer:
52 hours
Step-by-step explanation:
Given that it takes 15 orders every 5 hours.
With that we can find that it takes 3 orders every hour. Using that we can find that in 52 they would have shipped 156 orders

Answer:
The percentage of the guests at this hotel called for room service yesterday is 40%
Step-by-step explanation:
We are given
total number of guests called for room services =170
total number of guests did not called for room services =255
now, we can find total number of guests
Total number of guests =(total number of guests called for room services)+(total number of guests did not called for room services)
so,
total number of guests is
=170+255
=425
now, we can find percentage
percentage of the guests at this hotel called for room service yesterday is
%
So,
The percentage of the guests at this hotel called for room service yesterday is 40%
Answer: 0.4x + 0.1
Step-by-step explanation: Distribution.
0.5(x+0.1)-0.1(x-0.5)
0.5 times x = 0.5x
0.5 times 0.1 = 0.05
First step: 0.5x + 0.05
Distribute next part
-0.1 times x= -0.1x
-0.1 times -0.5 = 0.05
-0.1x + 0.05
Put together: 0.5x + 0.05 -0.1x + 0.05
Combine like terms:
0.5x -0.1x = 0.4x
0.05 + 0.05 = .1
Answer: 0.4x + 0.1
