What constant term should be used to complete the square? x 2 - 5x + _____ = 7
amm1812
The quadratic equation in its generic form is:
 ax2 + bx + c
 To complete squares we must add the following term:
 (b / 2) ^ 2
 The equation is:
 ax2 + bx + c + (b / 2) ^ 2
 We have the following equation:
 x ^ 2 - 5x + k = 7
 By completing squares we have:
 x ^ 2 - 5x + (-5/2) ^ 2 = 7 + (-5/2) ^ 2
 Rewriting:
 x ^ 2 - 5x + 6.25 = 7 + 6.25
 Answer:
 
A constant term should be used to complete the square is:
 
6.25

A sphere has a diameter of 12.5 inches. What is the surface area of the sphere? 50π in² 156.25π in² 625π in² 2604.17π in²
Advocard [28]
Hello!

To find the surface area of a sphere you use the equation

A = 4 \pi  r^{2}

A is surface area
r is radius which is half the diameter

Put in the values you know

A = 4 \pi 6.25^{2}

Square the number

A = 4 \pi 39.0625

Multiply the 4 and the 39.0625

A = 156.25 \pi

The answer is B) 156.25 \pi  in^{2}

Hope this helps!
