If two planes intersect, they intersect in a line. Two planes that do notintersect are called parallel. Given a plane and a line, there are three possibilities. The line and the plane intersect in a single point.

Two planes may intersect, be parallel, or coincide .

If two planes intersect, then the set of common points is a line that lies in both planes. Two parallel planes can not intersect.

The intersection of two planes that do not coincide (if it exists) is always a line.

If an intersection of the planes does not exist, the planes are said to be parallel.

What is the factor of 25a2+b2?

Neko [114]

Answer:

(5a+b)⋅(5a−b)

Step-by-step explanation:

Changes made to your input should not affect the solution:

(1): "b2" was replaced by "b^2". 1 more similar replacement(s).

STEP

Equation at the end of step 1

52a2 - b2

STEP

Trying to factor as a Difference of Squares

2.1 Factoring: 25a2-b2

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 25 is the square of 5

Check : a2 is the square of a1

Check : b2 is the square of b1

Factorization is : (5a + b) • (5a - b)

AC is tangent to circle O at A. The Diagram is not to scale.

statuscvo [17]

Answer:

B. 64°

Step-by-step explanation:

Given:

mBY = 52°

Inscribed angle measure is half the intercepted arc:

m∠BAY = 1/2(52°) = 26°

The angle between the diameter and tangent is right angle:

m∠BAC = 90°

According to angle addition postulate:

m∠YAC = m∠BAC - m∠BAY
m∠YAC = 90° - 26° = 64°

Correct choice is B

Can someone help me?

Natasha2012 [34]

Answer:

The symbols that we will use are:

a > b (a is larger than b)

a < b (a is smaller than b)

a ≥ b (a is larger than or equal to b)

a ≤ b (a is smaller than or equal to b).

1) if x represents the inches of snow, we have:

"More than 4 inches" means that x must be strictly larger than 4 inches, this can be written as:

x > 4 inches.

2) "less than 25 inches" means that x must be strictly smaller than 25 inches, this can be written as:

x < 25 inches.

3) If T represents the temperature

"No more than 8°F" means that the temperature can be smaller than 8°F, or equal to 8°F, then we can write this situation with:

T ≤ 8°F

4) "At least 7°F" means that the temperature can be 7°F or more than that, then we can write this situation as:

T ≥ 7°F

How do i do diss plss

ira [324]

Answer

Assuming you want an explanation and now numbers VVV

Step-by-step explanation:

The first column says those are the measurements for four people, since two is half of four you can divide all those measurements in half to fill out the "2 people" collum. To fill out the rest of the columns justs take the amount you just multiply. For example you'd need 1 tbsp of butter for two people, to find how much you need for six you multiply that by 3.

If you have any questions please ask, i hope this helps!
