Answer:
ldk Sry
Step-by-step explanation:
Answer: The answer is x=2/3
Step-by-step explanation: This is the linear equation to solve it we have to take 6x to the other the sign will change to be negative then divide both sides by 3
3x=6x-2
3x-6x=-2
3x=-2
x=2/3
The answer is A decrease of 13 degrees
Answer:
10:30am
Step-by-step explanation:
total lesson time is 1 hr and 15 min (10 to 11:15).
lesson time is 1 hr total and the break mid way is :15 long.
the lesson before the break is from 10-10:30 (:30 length)
break is at 10:30 (:15 long concluding at 10:45).
lesson resumes at 10:45 when break is over
the lesson runs another :30 until 11:15 (10:45-11:15)
halfway thru the lesson is 10:30am for the break to start
The generic equation of a third degree polynomial is given by:
y = ax ^ 3 + bx ^ 2 + cx + d
We must make a system of equations to find the values of a, b, c, d.
We have then:
For (1, 3):
3 = a (1) ^ 3 + b (1) ^ 2 + c (1) + d
3 = a + b + c + d
For (2, -2):
-2 = a (2) ^ 3 + b (2) ^ 2 + c (2) + d
-2 = 8a + 4b + 2c + d
For (3, -5):
-5 = a (3) ^ 3 + b (3) ^ 2 + c (3) + d
-5 = 27a + 9b + 3c + d
For (4.0):
0 = a (4) ^ 3 + b (4) ^ 2 + c (4) + d
0 = 64a + 16b + 4c + d
We obtain the following system of equations:
3 = a + b + c + d
-2 = 8a + 4b + 2c + d
-5 = 27a + 9b + 3c + d
0 = 64a + 16b + 4c + d
Whose solution is:
a = 1
b = -5
c = 3
d = 4
The polynomial will then be:
y = x ^ 3 - 5x ^ 2 + 3x + 4
Answer:
y = x ^ 3 - 5x ^ 2 + 3x + 4
