Answer:
Make the 8 worth 10 times as much.
Step-by-step explanation:
The correct answer is B) m=-8
First, add 9 on both sides of the equation. You should end up with 4m=-32.
Next, divide both sides of the equation by 4. You should end up with m=-8. (A negative divided by a positive equals a negative)
Hope this helps! Have a great day ;)
Answer:
- 3.68 feet using given equation (wrong)
- 12.5 feet using correct equation
Step-by-step explanation:
You can use the given (incorrect) equation and fill in the value of t to find h:
h = 12.5 +9sin(750(3.5)) = 3.68 . . . . feet
__
Or, you can use the correct equation, or just your knowledge of revolutions:
h = 12.5 +9sin(750(2π·3.5)) = 12.5 . . . . feet
in 3.5 minutes at 750 revolutions per minute, the propeller makes 2625 <em>full revolutions</em>, so is back where it started — at 12.5 feet above the ground.
The new polynomial identity is 2(x² + 2xy + y²)
Given,
The polynomial identities
Column A Column B
(x − y) (x2 + 2xy + y2)
(x + y) (x2 − 2xy + y2)
(y + x) (ax + b)
(y − x) (cy + d)
We have to square an identity from column A and add it with any one identity from column B.
So,
Lets take (x + y)
(x + y)² = x² + 2xy + y²
We can add this identity with x² + 2xy + y² in column B.
That is,
x² + 2xy + y² + x² + 2xy + y²
= 2x² + 4xy +2 y²
= 2(x² + 2xy + y²)
That is,
The new polynomial identity is 2(x² + 2xy + y²)
