Answer:
Step-by-step explanation:
The formula for the surface area of a cylinder is:
And we want to solve for the height h.
First, subtract 
from both sides. This yields:
Now, divide both sides by 
. This yields:
And we're done!
Answer:
4
Step-by-step explanation:
Given
x² - 4x + 10 = 0
subtract 10 from both sides
x² - 4x = - 10
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 2)x + 4 = - 10 + 4
(x - 2)² = - 6
To complete the square add 4
Answer:
Option D: 
is the correct answer.
Step-by-step explanation:
Given that:
3/4 inches on map are equal to 
miles
We will find the unit rate in term of inches.
Total distance covered by Bonnie according to map;
Total distance = 
Total distance = 
Actual distance = 
Actual distance = 
Hence,
Option D: is the correct answer.
Given h is the height, H is the hypotenuse and A is the base angle,
then Sin(A) = h/H
so h = HSin(A)
Answer: $3 per pound
Step-by-step explanation:
Since Carson buys 4 pounds of peaches for $12, you can find the value of one pound by dividing 4 by 4. You must also divide the 12 by 4. In conclusion, you pay $3 per pound.
