Step-by-step explanation:
Given function:
Table and graph are attached
Zeros are included in the graph
<u>Zero's are obtained:</u>
x = 0 ⇒ y = 8
y = 0 ⇒ Solving quadratic equation
- -2x² + 5x + 8 = 0
- x = (-5 ± √(25 + 2*4*8))/-4
- x = 3.608
- x = -1.108
So zeros are (0, 8), (3.608, 0) and (-1.108, 0)
Answer:
Step 3: Add those deviations together.
Step-by-step explanation:
Answer:
1400
Step-by-step explanation:
2/5×1000=400
1000+400=1400
First, you are going to want to get the terms to the same power of 10 in scientific notation. Realize that 
. Essentially, we have converted the 
to a term with 
. Now, we can subtract the values in each term that are not 10 as shown below:
Remember that we have to turn it back to scientific notation once we are done!
Our answer is the second choice, 
. (This is the closest answer to 
.)
Answer:
A = 1, B = 1
Step-by-step explanation:
From the question
(2x+1)/(x²+x) = A/x + B/(x+1)
(2x+1)/(x²+x) = [A(x+1)+(Bx)]/(x²+x)
Equation the numerator
2x+1 ≡ A(x+1) +Bx
2x+1 ≡ Ax+A+Bx
From the above,
A = 1.
And,
2x = Ax+Bx................ Equation 1
A+B = 2
Substitute the value of A into Equation 1
1+B = 2
B = 2-1
B = 1
