find the solutions for this polynomial equation 3(x − 2)(x2 − 9)(x + 7) = 0
Answer: If the x2-9 is x^2-9, then this is the answer. If not and it's supposed to be 2x then the answer is x=2 or x=−7 or x=9/2
Step-by-step explanation:
3(x−2)(x2−9)(x+7)=0
3x4+15x3−69x2−135x+378=0
Step 1: Factor left side of equation.
3(x−2)(x+3)(x−3)(x+7)=0
Step 2: Set factors equal to 0.
x−2=0 or x+3=0 or x−3=0 or x+7=0
x=2 or x=−3 or x=3 or x=−7

What are the coordinates of the point on the directed line segment from (3, -3) to
(7,5) that partitions the segment into a ratio of 5 to 3?
Answer:
(5.5, 2)Step-by-step explanation:
Points given:
(3, -3) and (7,5)Partition ratio:
5 to 3Formula for the point:
x = x1 + a/(a+b)×(x2 - x1) y = y1 + a/(a +b)×(y2 - y1)So the points are:
x = 3 + 5/(5+3)×(7-3) = 3 + 5/8×4 = 5.5y = -3 + 5/8×(5 - (-3)) = -3 + 5/8×8= 2Answer:

Perform the indicated operation. 13 – (-4) 1 -1 17 -17
Answer:
sorry about being late! 17, C
Step-by-step explanation:
It's 13+4 since there are two negatives.
Two negatives cancel out to a postive in math, so it becomes 13 + 4.
13+ 4
= 17

Find the fraction and the ratio of No. Of prime numbers to the numbers up to 50
Answer:
3/ 10
Step-by-step explanation:
Count of numbers up to 50 = 50
Prime numbers up to 50 :
{2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47}
Count of prime numbers up to 50 = 15
Hence, ratio of prime numbers to all numbers ;
15 : 50

Find the maximum value of
P = x + 6y
subject to the following constraints:
(2x + 4y < 10
X + 9y < 12
x > 0
y0
P = [?]
Answer:
(3, 1)
Step-by-step explanation:
Given the following constraints:
2x + 4y ≤ 10
x + 9y ≤ 12
x ≥ 0
y ≥ 0
We have to first graph the above constraints and secondly, we find the boundary points for the feasible region. This is done by plotting the graphs of 2x + 4y ≤ 10 and x + 9y ≤ 12.
From the graph, the following points satisfy the constraints:
(0,0) , (3,1) , (0,4/3) , (5,0)
Given that:
P = x + 6y
For (0, 0): P = x + 6y = 0 + 6(0) = 0
For (3, 1): P = x + 6y = 3 + 6(1) = 9
For (0, 4/3) P = x + 6y = 0 + 6(4/3) = 8
For (5, 0) P = x + 6y = 5 + 6(0) = 5

What is the number of cycles of y=1/8cos(5θ+π/6)+3 between 0 and 2π?
You are correct. The answer is B) 5.
This is because the period here is T = 2pi/5
Multiplying 5 with this period leads to 5*(2pi/5) = 2pi; showing that 5 full cycles occupy a total horizontal width of 2pi units (more specifically stretching from 0 to 2pi).
