Multiplication of the given matrix is not possible by definition of matrix multiplication.
Since, To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
We have to given that;
Expression for multiply,
⇒ [4, 0, -1, 2, -3, -1] x [0, 1, -3, 1]
Since, We can see that;
First matrix have order 1 x 6
And, Second matrix have order 1 x 4
We know that;
Matrix multiplication is possible when number of column in first matrix is same as number of rows in second matrix.
Hence, By given matrices we get;
Number of column in first matrix (6) ≠ number of rows in second matrix (1)
So, Multiplication of the given matrix is not possible by definition of matrix multiplication.

The results after simplifying a linear equation are shown. Which result shows exactly one solution?
The only equation from the options given which shows exactly one solution is x = 2
Evaluating the options given :
x = x ; here, the variable on the right hand side is equal to that on the left hand side, this means there is no value for the variable x. x = 2 ; here, the value of varibale x is 2 ; with the equal to sign, it means 2 is the only value which makes x true, hence the only solution. 1 = 1 ; Here, there is no variable to which the value of 1 is attached, hence, no solution. 0 = 1 ; 0 is not equal to 1.Therefore, only the equation x =2 gives exactly one solution for the value of x

Mr. Hooper has a tree in his front yard that grows every year. If the tree was 3 feet tall when he planted it 6 years ago , what is the current height of the tree in terms of f?
A. 3f + 6 feet
B. 6f + 3 feet
C. 3f + 18 feet
D. 6f + 18 feet
The height of the tree after 6 years can be expressed as "3 feet + 6f feet."
The correct answer is A. 3f + 6 feet.
To determine the current height of the tree in terms of "f,"
let's analyze the given information.
We know that the tree was initially 3 feet tall when it was planted 6 years ago.
Since the tree grows every year, we can assume that its growth rate is consistent.
Let's denote the current height of the tree as "h" (in feet).
After 6 years, the tree has grown by a certain amount, which we'll represent as "6f" (6 years multiplied by the growth rate "f").
Therefore, the height of the tree after 6 years can be expressed as "3 feet + 6f feet."

A zip wire runs between two posts, 25m apart. The zip wire is at an angle of 10∘ to the horizontal. Calculate the length of the zip wire.
The length of the zip wire is approximately 25.42 meters.
To calculate the length of the zip wire, we can use trigonometry and the given information about the angle and the distance between the two posts.
Given:
Distance between the two posts: 25m
Angle of the zip wire to the horizontal: 10°
We can use the trigonometric function cosine (cos) to find the length of the zip wire. Cosine relates the adjacent side to the hypotenuse of a right triangle.
In this case, the adjacent side is the distance between the two posts (25m) and the hypotenuse is the length of the zip wire that we want to calculate.
Using the cosine function:
cos(angle) = adjacent/hypotenuse
cos(10°) = 25m/hypotenuse
To find the hypotenuse (length of the zip wire), we can rearrange the equation:
hypotenuse = 25m / cos(10°)
Using a calculator or trigonometric tables, we can find the value of cos(10°) to be approximately 0.9848.
Therefore, the length of the zip wire is:
hypotenuse = 25m / 0.9848 ≈ 25.42m

4) Solve ∆ABC, a = 2.5 cm, c = 3.6 cm, and ∠A = 43°. Begin by sketching and labelling
a diagram. Account for all possible solutions. Express each angle to the nearest
degree and each length to the nearest tenth of a unit.
The length of b and angle B and C are 2. 9cm, 44. 9 degrees and 79. 11 degrees respectively.
How to determine the parametersTo determine the angles and length of sides, we use the sine rule
The sine rule is thus:
\(\frac{sin A}{a} = \frac{sin B}{b} = \frac{sin C}{c}\)
Given;
a = 2. 5cmc = 3. 6cm∠A = 43°Let's find angle C
\(\frac{sin 43}{2. 5} = \frac{sinC}{3. 6}\)
cross multiply
0. 682 × 3. 6 = sin C × 2. 5
sin C = 2. 4552/ 2. 5
C = \(sin^-^1( 0. 98206)\)
C = 79. 11°
To find length of b
b = \(\sqrt{c^2 - a^2}\)
substitute the values
b = \(\sqrt{3. 6^2 - 2. 5^2}\)
b = \(\sqrt{12. 96 - 6. 25 }\)
b = \(\sqrt{6. 71}\)
Take square root
b = 2. 59 cm
To find angle B, we have
\(\frac{sin 43}{2. 5} = \frac{sin B}{2. 59}\)
cross multiply
0. 682 × 2. 59= sin B × 2. 5
sin B = 0. 7066
B = \(sin^-^1 ( 0. 7066)\)
B = 44. 9 °
Thus , the length of b and angle B and C are 2. 9cm, 44. 9 degrees and 79. 11 degrees respectively.

The height of the right circular cylinder shown below is 10 feet and its base has a radius of 4 feet.
The surface area of cylinder whose height is 10 feet and its base of radius is 4 feet is 112π \(ft^{2}\)
What is volume of cylinder ?
volume of cylinder is product of pi and square of radius and height of the cylinder.
Given,
height of cylinder = 10 feet
base of radius of cylinder = 4 feet.
Surface area of cylinder is
A=2πrh+2πr2
A = π (2rh+2r2)
A = π (2*4*10 + 2* 4*4)
A =π(80+32)
A = 112 π \(ft^{2}\) .
Hence, the surface area of cylinder whose height is 10 feet and its base of radius is 4 feet is 112π \(ft^{2}\).

tickets to a movie cost $10.50 for adults and $7.25 for students. you and a few friends purchased 8 tickets for $61.25. how many adult tickets and student tickets were purchased?
Answer:
1 adult ticket and 7 student tickets were purchased
Step-by-step explanation:
let a represent number of adult tickets purchased and s the number of student tickets purchased, then
a + s = 8 ( subtract s from both sides )
a = 8 - s → (1) ← based on total tickets purchased
10.5a + 7.25s = 61.25 → (2) ← based on cost of tickets
substitute a = 8 - s into (2)
10.5(8 - s) + 7.25s = 61.25
84 - 10.5s + 7.25s = 61.25
84 - 3.25s = 61.25 ( subtract 84 from both sides )
- 3.25s = - 22.75 ( divide both sides by - 3.25 )
s = 7
substitute s = 7 into (1)
a = 8 - 7 = 1
that is 1 adult ticket and 7 student tickets were purchased

What are the Medians?
The median number of hours slept by boys the previous night is 6.5 hours, while the median number of hours slept by girls the previous night is 7 hours.
The given line plots display the results of a survey of 10 boys and 10 girls regarding the number of hours they slept the previous night. To find the median, follow these steps:Put the observations in ascending order.Divide the data into two equal parts.
To locate the median of the data, find the value that is at the center of the data when ordered.To calculate the medians of the given line plots, we must first arrange the observations in ascending order and divide them into two equal parts.
We have 10 boys and 10 girls in total, so we will have 20 observations for each line plot: Boys’ line plot: 4, 5, 6, 6, 6, 7, 7, 8, 9, 10Girls’ line plot: 5, 5, 6, 7, 7, 7, 7, 8, 8, 10When arranged in ascending order,
the observations are as follows: Boys’ line plot: 4, 5, 6, 6, 6, 7, 7, 8, 9, 10Girls’ line plot: 5, 5, 6, 7, 7, 7, 7, 8, 8, 10 Now,
we must determine the medians for each data set. Since each data set has an even number of observations, the median is the average of the two middle values.
The medians for each data set are as follows: Boys’ line plot: (6 + 7) / 2 = 6.5Girls’ line plot: (7 + 7) / 2 = 7
