Step-by-step explanation:
The \(3\times 3\) matrix will be "\(\left[\begin{array}{ccc}0.3&0&-1.8\\0&1.3&3.9\\0&0&1\end{array}\right]\)".
According to the question,
The \(3\times 3\) with homogenous coordinates is:
\(\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right]\)
Translation from (0, 0) to (a, b) will be:
\(T = \left[\begin{array}{ccc}1&0&a\\0&1&b\\0&0&1\end{array}\right]\)
Here,
a = -6b = 4Translation by (-5,4)
\(T = \left[\begin{array}{ccc}1&0&-6\\0&1&3\\0&0&1\end{array}\right]\)
Now,
Let's find the scaling matrix 5.Scale the x-coordinated by "0.3" and y-coordinates by "1.3".i.e.,
\(S = \left[\begin{array}{ccc}0.3&0&0\\0&1.3&0\\0&0&1\end{array}\right]\)
then,
The \(3\times 3\) matrix will be:
→ \(A = ST\)
\(= \left[\begin{array}{ccc}0.3&0&0\\0&1.3&0\\0&0&1\end{array}\right] \ \left[\begin{array}{ccc}1&0&-6\\0&1&3\\0&0&1\end{array}\right]\)
\(= \left[\begin{array}{ccc}0.3&0&-0.3\times 6\\0&1.3&1.3\times 3\\0&0&1\times 1\end{array}\right]\)
\(= \left[\begin{array}{ccc}0.3&0&-1.8\\0&1.3&3.9\\0&0&1\end{array}\right]\)

one card is drawn from a pack of 52cards each of the 52 cards being equally likely to be drawn. what is the probability that the card drawn is a king?
The probability of drawing a king from a standard deck of 52 cards is 1/13.
In a standard deck of 52 playing cards, there are four kings: the king of hearts, the king of diamonds, the king of clubs, and the king of spades.
To find the probability of drawing a king, we need to determine the ratio of favorable outcomes (drawing a king) to the total number of possible outcomes (drawing any card from the deck).
The total number of possible outcomes is 52 because there are 52 cards in the deck.
The favorable outcomes, in this case, are the four kings.
Therefore, the probability of drawing a king is given by:
Probability = (Number of favorable outcomes) / (Number of possible outcomes)
= 4 / 52
= 1 / 13
Thus, the probability of drawing a king from a standard deck of 52 cards is 1/13.
This means that out of every 13 cards drawn, on average, one of them will be a king.
It is important to note that the probability of drawing a king remains the same regardless of any previous cards that have been drawn or any other factors.
Each draw is independent, and the probability of drawing a king is constant.

3. Two equations to solve for m are given as follows:
n² + m² = l².m = square root (l² - n²).4. The length of the hypotenuse of the triangle is given as follows: 7.9 inches.
5. The lengths are given as follows:
BD = 4.3 cm.BC = 11.5 cm.What are the trigonometric ratios?The three trigonometric ratios are given as follows:
Sine of angle = length of opposite side divided by the length of the hypotenuse.Cosine of angle = length of adjacent side divided by the length of the hypotenuse.Tangent of angle = length of opposite side divided by the length of the opposite side.In the second problem, we have that the side x is opposite to the angle of 52º, while the hypotenuse is of 13, hence the equation to solve for x is given as follows:
sin(52º) = x/13.
In item 3, the Pythagorean Theorem is used to solve for m, as follows:
n² + m² = l².
m² = l² - n²
m = square root (l² - n²).
In item 4, we have that the angle opposite to the leg of length 7 inches is of 62º, hence the hypotenuse is given as follows:
sin(62º) = 7/h
h = 7/sin(62º)
h = 7.9 inches.
The length BD in item 5 is obtained as follows:
cos(30º) = BD/5
BD = 5 x cos (30º)
BD = 4.3 cm.
Then the length BC is calculated as follows:
sin(22º) = 4.3/BC
BC = 4.3/sin(22º)
BC = 11.5 cm.

y = x2+6x+8 and y = (x+2)(x+4) both define the same quadratic function. Without graphing, identify the x- and y-intercepts of the graph.
Put each of the intercepts in the form of an ordered pair ( . ) ( . ).
You should have three ordered pairs in your answer. Two x-intercepts and one y-intercept.
Answer:
x-int:(-2,0)(-4,0) . y-int:(0,8)
Step-by-step explanation:
y = x2+6x+8 and y = (x+2)(x+4)
x-int:
x+2=0
x= -2
(-2,0)
x-int:
x+4=0
x=-4
(-4,0)
y-int: plug 0 for x
y=(0+2)(0+4)
y=8
(0,8)
The intercepts of a graph are the points where the graph crosses the x or y axes.
The x-intercepts are: (-2,0) and (-4,0)The y intercept is (0,8)Given that:
\(y = x^2 + 6x + 8\)
\(y = (x + 2)(x + 4)\)
The x-intercepts
This is when \(y = 0\)
So, we have:
\(y = (x + 2)(x + 4)\)
\((x + 2)(x + 4) = 0\)
Split
\((x + 2) = 0\) or \((x + 4) = 0\)
Solve for x
\(x = -2\) or \(x = -4\)
Hence, the x-intercepts are: (-2,0) and (-4,0)
The y-intercepts
This is when \(x = 0\)
So, we have:
\(y = x^2 + 6x + 8\)
Substitute 0 for x
\(y = 0^2 + 6 \times 0 + 8\)
\(y = 8\)
Hence, the y intercept is (0,8)

Ben wants to buy a new collar for each of his 5 dogs. The collars come in a choice of 9 different colors. Step 1 of 2 : How many selections of collars for the 5 dogs are possible if repetitions of colors are allowed
Answer:
59049 ways
Step-by-step explanation:
Given
\(Colors = 9\)
\(Dogs = 5\)
Required
Determine number of selection (repetition is allowed)
The number of collars is not given.
So, we'll assume that there are enough collars to go round.
If no repetition is allowed, each of the 5 dogs have 9 colours to select from.
i.e.
\(Dog\ 1 = 9\)
\(Dog\ 2 = 9\)
\(Dog\ 3 = 9\)
\(Dog\ 4 = 9\)
\(Dog\ 5 = 9\)
So, the number of selection is:
\(Selection = 9 * 9 * 9 * 9 * 9\)

∫ (log(1 + x ^ 2))/((x + 1) ^ 2) dx
The final result of the integral is:
∫ (log(1 + x²) / (x + 1)²) dx = log(x + 1) - 2 (log(x + 1) / x) - 2Li(x) + C,
where Li(x) is the logarithmic integral function and C is the constant of integration.
We have,
To solve the integral ∫ (log(1 + x²) / (x + 1)²) dx, we can use the method of substitution.
Let's substitute u = x + 1, which implies du = dx. Making this substitution, the integral becomes:
∫ (log(1 + (u-1)²) / u²) du.
Expanding the numerator, we have:
∫ (log(1 + u² - 2u + 1) / u²) du
= ∫ (log(u² - 2u + 2) / u²) du.
Now, let's split the logarithm using the properties of logarithms:
∫ (log(u² - 2u + 2) - log(u²)) / u² du
= ∫ (log(u² - 2u + 2) / u²) du - ∫ (log(u²) / u²) du.
We can simplify the second integral:
∫ (log(u²) / u²) du = ∫ (2 log(u) / u²) du.
Using the power rule for integration, we can integrate both terms:
∫ (log(u² - 2u + 2) / u²) du = log(u² - 2u + 2) / u - 2 ∫ (log(u) / u³) du.
Now, let's focus on the second integral:
∫ (log(u) / u³) du.
This integral does not have a simple closed-form solution in terms of elementary functions.
It can be expressed in terms of a special function called the logarithmic integral, denoted as Li(x).
Therefore,
The final result of the integral is:
∫ (log(1 + x²) / (x + 1)²) dx = log(x + 1) - 2 (log(x + 1) / x) - 2Li(x) + C,
where Li(x) is the logarithmic integral function and C is the constant of integration.

What is the Surface Area of a Trapezium Prism?Surface area of trapezium prism = (b1+b2)h + PH.
Given the following:
Surface area of trapezium prism = 1508 sq. ftb1 = 35 ftb2 = 11 fth = 14 ftP = 50 ftH = ? (height of the prism)Substitute the values into (b1+b2)h + PH:
1508 = (35 + 11)14 + (50)H
1508 = 644 + 50H
1508 - 644 = 50H
864 = 50H
H = 17.3 ft
