If you would like to find the value of a in the polynomial, you can do this using the following steps:
(y - 4)(y^2 + 4y + 16) = y^3 + 4y^2 + 16y - 4y^2 - 16y - 64 = y^3 + 4y^2 + ay - 4y^2 - ay - 64
a = 16
The correct result would be 16.
We know angle P is 90 degrees because of Thales Theorem, and angle N is 60 degrees. Because the angles in a triangle have to add up to 180 degrees, angle PMN has to be 30 degrees.
Angle QMO is half of angle PMN, so it's 15 degrees. Angle MQO is equal to angle QMO because the radii make Triangle OQM isosceles, so angle MQO is 15 degrees.
Answer:
Step-by-step explanation:
The formula of a surface area of a sphere:
R - radius
We have
Substitute and solve for R:
<em>divide both sides by π</em>
<em>divide both sides by 4</em>
The formula of a volume of a sphere:
Substitute:
Make them the same demonatator so 7/8 times 2/8 which equals 14 over 8 for a mixed number of 1 6/8
