Answer: D
Step-by-step explanation:
Isosceles Triangle has 3 sides, that has 2 sides of equal length.
Equilateral Triangle has 3 sides, that has 3 sides all of equal length.
If you have heard of the Hypotenuse, it has 3 sides of all different lengths maybe that's what this? But, the answer would indeed be D. Form Neither an equilateral nor an isosceles triangle.
Happy Mathing!!
Given:
The matrix statements in the options.
To find:
The answer choice that show the commutative property does not hold for matrix multiplication.
Solution:
We known that matrix multiplication is not commutative. if A and B are two non-zero matrices, then

Let us assume,

According to the above property of the matrix, we get

Therefore, the correct option is B.

Answer:
, the third one
Step-by-step explanation:
Explaining the sine function:
The sine function is defined by:

In which A is the amplitude,
is the period,
is the horizontal shift and V is the vertical shift.
So, in your problem:
The amplitude is 4, so A = 4.
The period is
, so
.
There is no horizontal shift, so
.
The vertical shift is −3, so V = -3.
The sine function that represents these following conditions is
, the third one
