Answer:

Explanation is below.

Step-by-step explanation:

Commutative property:

The Commutative property states that order does not matter. Multiplication and addition are commutative.

For example 2+5=5+2 .

Associative property:

The associative property states that you can add or multiply regardless of how the numbers are grouped.

For example 2x(7x5)=(2x7)x5

Distributive property:

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

For example 2(x+y)=2x+2y

Zero property of addition:

Zero is the additive identity. Adding zero to a number will not change its value. a + 0 = a.

For example 2z + 0 = 2z

Identity property of multiplication:

Property is that multiplying any number by 1 allows the number to keep its identity.

For example 14 x 1 = 14

Additive inverse:

The additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite, sign change, and negation.

For example 13 + -13 = 0

What is the vertical distance from the origin to the point (8, 1)?
Cerrena [4.2K]

Answer:

The vertical distance is 1.

Explanation:

Coordinates are structured as ( x , y )

The "x" is horizontal and the "y" is vertical, when placed onto a graph.

In the question, 8 is "x" and 1 is "y". Meaning the vertical number is 1.

From the given sides of 16, 14, and 21, determine what type of triangle it will form (right, acute, obtuse, none).
Komok [63]

Answer:

It is an acute triangle.

Step-by-step explanation:

It would be much easier for you to see where I'm getting at if you draw a diagram.

Assume this triangle is labelled ABC where a = 14, b = 21, and c = 16.

cos A = (16^2 + 21^2 - 14^2)/(2(16)(21))

∠A = cos^-1(0.82291...)

∠A ≅ 34.6°

cos B = 16^2 + 14^2 - 21^2)/(2(16)(14))

∠B = cos^-1(0.024...)

∠B ≅ 56.8°

∠C = 180 - (∠A + ∠B)

∠C ≅ 56.8°

Since there is no right-angle nor is there an obtuse angle,

Therefore the triangle is an acute triangle.
