To complete the square, you add $\frac{b}{2}^2$ to both sides

so $\frac{4}{2}^2$

$2^2$

$x^2 - 4x + 4=7 + 4$

Angle 3 is a supplement of angle 4. If the m of angle 3 is 100 degrees, what is the m of angle 4?

Triss [41]

Answer: 80

Step-by-step explanation: Supplements mean they add up to 180. is m of 3 is 100, then m of 4 must be 80 to add up to 180. Hope this helps!

Mike scored a 125 at a semi-final dividing competition season. He scored 95 at this final season. What is the percentage decreas

IrinaK [193]

Answer:

There was a 24% decrease

Step-by-step explanation:

Percentage decrease = (final season's score - semi-final score) / semi final score x 100

$\frac{95-125}{125}$ ×100

$\frac{-30}{125}$ × 100 = -24%

marin [14]

Answer: hi your question is incomplete below is the complete question

Use the Divergence Theorem to calculate the surface integral S F dS   with F x y z = , , and S is a sphere centered at the origin with a radius of 2. Confirm your answer by computing the surface integral

answer : surface integral = 384/5 π

Step-by-step explanation:

Representing the vector field as

F ( x, y , z ) = ( a^3 + y^3 ) + ( y^3 + z^3 ) + ( Z^3 + x^3 ) k

assuming the sphere ( s) with radius = 2 be centered at Origin of the vector field.

Hence the divergence will be represented as :
