Answer:
Correct answer is: A = 8 m π
Step-by-step explanation:
In fact, it is necessary to calculate the surface of the circular ring representing the circular window frame:
It's formula:
A = (R² - r²) π where R = m + 2 and r = m - 2
A = ((m + 2)² - (m - 2)²) π = (m + 2 + m - 2) (m + 2 - m +2) π = 2m · 4 π
A = 8 m π

Answer:
Jacket A costs 43$
Jacket B costs 55$
Step-by-step explanation:
According to the Question,
- Given, Two jackets have a combined cost of $98. Jacket 'A' costs $12 less than jacket 'B'. Thus, if the jacket B Cost 'X' So, Jacket A costs 'X-12'.
Therefore, Jacket A + Jacket B = 98
X-12+X = 98
2X = 110
X = $55 ( Cost of jacket B) & Cost of Jacket A is 55-12 = 43$ .

Answer:
no solution
Step-by-step explanation:
These lines have the same slope and different y-intercepts, so graph as parallel lines. As such, they will have no point of intersection, so there is NO SOLUTION to this system of inconsistent equations.
Answer:
Y = √(R² - X²)
Step-by-step explanation:
∵ The two forces acting at right angles to each other
∴ The resultant force R = √(X² + Y²)
∴ R² = X² + Y²
∴ Y² = R² - X²
∴ Y = √(R² - X²)
Sin A = 9/41 because opposite to angle A is 9 and the hypotenuse is 41. sine is opposite over hypotenuse.
