<B ~ <C isosceles Triangle Theorem
The length of the side AB and AC will be congruent with each other. Then the triangle ΔABC will be an isosceles triangle.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
The two triangular legs and their opposing angles are congruent in an isosceles triangle.
In triangle ΔABC, then the length of the side AB and AC will be congruent to each other.
AB = AC
Then the triangle ΔABC will be an isosceles triangle.

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 12 N acts on a certain object, the acceleration
of the object is 6 m/s?. If the acceleration of the object becomes 4 m/s, what is the force?
Answers
Answer:
8N
Explanation:
Since Force is proportional to acceleration,
F1/a1=F2/a2
Therefore;
12/6=F2/4
F2=(12*4)/6

2.Y=6
3.Y=3
4.Y=5
Explanation:
In The first one our x values are
-2 -1 0 1 2 3
And our y values are
-2 -1 0 1 2 3
3 6
This one is easy cause you can see that it’s counting by 1. For example it goes 3, 4, 5, 6, 7, 8.
THE SECOND ONE
the table is
-1 0 1 2 3 4
4 16
Our y values are 4 and 16
Subtract 16 - 4
divided by 2
12 divided by 2 is 6.
4 + 6 = 10
10 + 6 = 16
So it checks out.
To find the numbers after 4, just subtract 4 from 6 and then subtract 6 from the answer you get.
THE THRID ONE
The table is
0 1 2 3 4 5
-1 8 14
14 - 8 = 6
6 divided by 2 is 3
-1 + 3 = 2
2 + 3 = 5
5 + 3 = 8
8 + 3 = 11
11 + 3 = 14 ✔️
So this works
THE FOURTH ONE
the table is
6 7 8 9 10 11
32 47 57
47 - 57 = 10
10 divided by 2 is 5
So let’s try it
32 + 5 = 37
37 + 5 = 42
42 + 5 = 47
47 + 5 = 52
52 + 5 = 57 ✔️
So this works

Can someone explain how the following Matrix can be multiplied? I thought the column of the first matrix had to match the row of the second and the row of the first had to match the column of the second. I how the matrices listed below as (1x3) and (3x3) respectively. Yet my online Pre-cal course says it's possible. Please explain why this is so.
Answers
You are correct in thinking that the columns of the first matrix must match with the rows of the second matrix.
So for example, we can multiply a 1 x 5 matrix with a 5 x 7 matrix. The two matching '5's are directly what make multiplication possible in this case. For your problem, the first two '3's match and multiplication is possible.
The rows of the first matrix don't need to match with the columns of the second matrix.

I hope this helps.
Answers
B=y
3=r the plaint 4 and y equals 2 and z
The value of x is 5 and the value of y is -13 which satisfies the equation. The correct option is C.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
The given equation is,
( x + yi ) + ( 4 + 9i ) = 9 - 4i
The points are x= 5 and y = -13,
( x + yi ) + ( 4 + 9i ) = 9 - 4i
( 5 -13i ) + ( 4 + 9i ) = 9 - 4i
5 + 4 -13i+9i = 9-4i
9-4i = 9 - 4i
Therefore, the value of x is 5 and the value of y is -13 which satisfies the equation. The correct option is C.

The correct statements are,
m∠R > 90°
m∠S + m∠T < 90°
m∠R > m∠T
m∠R > m∠S
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Here, RST is a triangle,
Therefore,
m∠R + m∠S + m∠T = 180°
⇒ m∠S+m∠T = 180° - m∠R
Since, m∠R > m∠S + m∠T
⇒ - m∠R < - (m∠S + m∠T) (by multiplying-1 on both sides)
⇒ 180°- m∠R < 180° - (m∠S + m∠T) (by adding 180° on both sides)
⇒ m∠S+m∠T < 180° - (m∠S + m∠T)
⇒ m∠S+m∠T+ m∠S+m∠T < 180° ( by adding m∠S + m∠T on both sides)
⇒ 2(m∠S+m∠T) < 180°
⇒ m∠S+m∠T < 90°
⇒ m∠R > 90° ( because m∠R+m∠S+m∠T = 180° )
Again, m∠R > m∠S + m∠T
⇒ m∠R > m∠S and m∠R > m∠T
Thus, Option first second fourth and fifth are correct.
Since, m∠S = m∠T is only possible when m∠R=90° (but it is not given)
That is why m∠S = m∠T is not correct.
And, there are not enough information to prove m∠S > m∠T
That is why m∠S > m∠T is also incorrect.
