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
God with you!!!
The answer would probably 22.7. 18 is a perfect square, -10/5 is -2 and -13.4 is a regular decimal
Answer: -3 and 2.
Step-by-step explanation:
I've attached the answer
Answer:
z= 20.78
x=16.97
y=12.00
Step-by-step explanation:
To find z , we need cosine function
To find x and y , we need to find the height of the left triangle , i.e.
24 sin 30 = 12
then cos 45 = 12 /x
x= 12/ cos 45 = 16.97
sin 45 = y/x = y/ 16.97
y= 16.97 sin 45 = 12
.
hope it help
If you would like to know what is f(2), you can calculate this using the following steps:
f(0) = 2
f(n+1) = - 2 * f(n) + 3
f(1) = - 2 * f(0) + 3 = - 2 * 2 + 3 = - 4 + 3 = - 1
f(2) = - 2 * f(1) + 3 = - 2 * (-1) + 3 = 2 + 3 = 5
The correct result would be f(2) = <span>5.</span>
