Answers
Answer:
Option B
Step-by-step explanation:
Looking at the options, option B is correct because when multiplying it by matrix A, it yields the matrix AB as follows;
First row of A multiplied by first column of matrix in option D;
(1 × -1) + (0 × 0) + (0 × 0) = -1 which corresponds to the first number on the first row of Matrix AB
Since majority of matrix AB are zero, I will just prove the ones that are not zero.
Thus;
Second row of matrix A is multiplied by second column of matrix in option D;
(0 × 0) + (-1 × -1) + (0 × 0) = 1 which is same as 2nd number on second row in matrix AB
Lastly, third row of matrix A is multiplied by third column of matrix in option D;
(0 × 0) + (0 × 0) + (1 × -1) = -1 which is same as third number in third row in matrix AB

B is the midpoint of AC. if AB = x+5 and BC = 2x-11, find the measure of AB
Answers
Answer:
2 is the answer
Step-by-step explanation:
Answer:
AB = 21
Step-by-step explanation:
Since B is the midpoint of AC , then
BC = AB
2x - 11 = x + 5 ( subtract x from both sides )
x - 11 = 5 ( add 11 to both sides )
x = 16
Then
AB = x + 5 = 16 + 5 = 21

What is an equation of the line that passes through the points (0, -3)(0,−3) and (-5, 3)(−5,3)?
Answers
Answer:
y = 6/5 x -3
Step-by-step explanation:
Standard equation of a line is expressed as;
y = mx+b
Slope m = y2-y1/x2-x1
Given the coordinates (0, -3)and (-5, 3)
Slope m = 3-(-3)/-5-0
Slope m = 6/5
Since the line cuts the y axis at y = -3, hence b = -3
GEt the required equation;
Recall that y = mx+b
y = 6/5 x + (-3)
y = 6/5 x -3
This gives the required equation

Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form. 20 10. 5
Answers
Given:
Consider the given terms of the sequence are:
20, 10, 5, ...
To find:
The type of sequence (arithmetic or geometric) and the common difference / ratio in simplest form.
Solution:
We have,
20, 10, 5, ...
Difference between consecutive terms are:
[tex]10-20=-10[/tex]
[tex]5-10=-5[/tex]
Since [tex]-10\neq -5[/tex], therefore the given sequence has no common difference, it means the given sequence is not arithmetic.
Ratio between consecutive terms are:
[tex]\dfrac{10}{20}=\dfrac{1}{2}[/tex]
[tex]\dfrac{5}{10}=\dfrac{1}{2}[/tex]
The given sequence has a common ratio [tex]\dfrac{1}{2}[/tex], it means the given sequence is a geometric sequence.
Therefore, the given sequence is a geometric sequence with common ratio [tex]\dfrac{1}{2}[/tex] it is also written as 0.5.

Place the indicated product in the proper location on the grid.
(2a^x+1/2b^x)^2
Answers
The expression [tex](2a^x + 1/2b^x)^2[/tex] will generally be located towards the upper right quadrant of the grid, with the term [tex]2a^x[/tex] positioned further to the right and the term [tex]1/2b^x[/tex] positioned further towards the top.
To determine the proper location of the expression [tex](2a^x+1/2b^x)^2[/tex] on the grid, let's analyze the components of the expression and their respective positions.
The given expression is [tex](2a^x + 1/2b^x)^2[/tex]. Breaking it down, we have two terms inside the parentheses: [tex]2a^x[/tex] and [tex]1/2b^x[/tex]. These terms consist of variables (a and b) raised to a power (x), along with coefficients (2 and 1/2) multiplying them.
On the grid, we can assign a specific axis for each variable: the horizontal axis for 'a' and the vertical axis for 'b'. The power 'x' indicates that the values will vary along these axes. Since we don't have specific values for 'a', 'b', or 'x', we cannot pinpoint exact locations on the grid.
However, we can make some general observations. The terms [tex]2a^x[/tex] and [tex]1/2b^x[/tex] will have different positions on the grid due to their coefficients. The term with the coefficient 2 will be relatively larger along the horizontal axis compared to the term with the coefficient 1/2, which will be relatively smaller along the vertical axis.
Hence, on the grid, we can expect the term [tex]2a^x[/tex] to be positioned towards the right side, while the term [tex]1/2b^x[/tex] will be positioned towards the top. The exponent '2' outside the parentheses indicates that the entire expression will be squared, so it will be further enlarged.

What is the m∠ADC ?
Enter your answer in the box

Answers
Answer:
Solution given:
m∠ADB=(4x−12)°
m∠CDB=(3x+6)°
m∠ADC =?
Since diagonal BD bisect the angle <ADC
so
m∠ADB= m∠ADC
(4x-12)°=(3x+6)°
4x-3x=6-12
x=12+6
x=18°
again.
<ADB=m∠ADB+ m∠ADC=4×18-12+3×18+6=120°
So
the m∠ADC =120°
