Answer:
25x^2 - 110x + 121.
Step-by-step explanation:
(5x − 11)^2
= (5x - 11)(5x - 11)
= 5x(5x - 11) - 11(5x - 11)
= 25x^2 - 55x - 55x + 121
= 25x^2 - 110x + 121.
Answer:
Step-by-step explanation:
Diameter:
from this information we can find the radius of the golf ball:
A golf ball is shaped like a sphere, and the formula for finding the volume of a sphere is:
where r is the radius and is a constant:
we substitute the values of pi and the radius to find the volume:
the closest to the volume of a golf ball:
Answer:
Step-by-step explanation:
Using the diagram, we can see that the angle is a right angle.
With this information, we can set up an equation:
Please note that right angles are always equivalent to 90 degrees.
Add like terms:
Subtract 82 from both sides:
Divide both sides by 8
500•1.1= 550, 320•1.1= 352, 80•1.15= 92, 75•1.25= 93.75
