Maria is making blueberry muffins using a blueberry cake recipe. To make the muffins, she has to divide the cake recipe in half.

I think she would have to divide 2/3 by 1/2. So you would do 2/3 x 2/1 and since 2/1 is equal to 2 the answer would be B Hope this helped - Ashlynn

I believe this is right:
Least: 8 (length) x 1 (width) = 8
Greatest: 5 (length) x 4 (width) = 20
Difference: 20 - 8 = 12

Write the condition that Ix + my + n = 0 may be a tangent to the circle x²+y² + 2gx + 2fy +C =0

uranmaximum [27]

Answer:

$r= \frac{ |c - lg - fm| }{ \sqrt{ {l}^{2} + {m}^{2} } }$

Step-by-step explanation:

The given circle has equation

${x}^{2} + {y}^{2} + 2gx + 2fy + c = 0$

This circle has centre (-g,-f).

For the line

$lx + my + n = 0$

to be a tangent to this circle, the perpendicular distance from the center to this line must be equal to the radius of the circle.

This is given by:

$d = \frac{ |ax + by + c| }{ \sqrt{ {a}^{2} + {b}^{2} } }$

We substitute the center and radius to get:

$r=\frac{ |l \times - g + m \times - f+ c| }{ \sqrt{ {l}^{2} + {m}^{2} } }$

We simplify to get;

$r= \frac{ |c - lg - fm| }{ \sqrt{ {l}^{2} + {m}^{2} } }$

Help Fast Please!!!!!!!!! How can you tell if three positive numbers form a Pythagorean triple?

Fiesta28 [93]

Answer/Step-by-step explanation:

Square all three numbers. If the largest number squared is equal to the sum of the squares of the other two, then the numbers form a Pythagorean triple.

or

Since a Pythagorean triple is three positive integers a, b, and c such that (a^2)+(b^2)=(c^2), first take the sum of the squares of the two legs and make an estimate. For example, 3, 4, and 5 is a Pythagorean triple since 9+16=25

either one works
