Step-by-step explanation:

Step-by-step explanation:

For example, if you have:

[tex]\left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right][/tex]

Then, your answer would be:

[tex]\left[\begin{array}{ccc}2&4&6\\8&10&12\\14&16&18\end{array}\right][/tex]

Because each term is the double of the original matrix.

[tex]aM=a\left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right] = \left[\begin{array}{ccc}1a&2a&3a\\4a&5a&6a\\7a&8a&9a\end{array}\right][/tex]

In fewer words, the scalar will multiply each element of the matrix.

Answer:

The 13.2 meters from that point on the ocean floor to the wreck.

Step-by-step explanation:

As given

A ship's sonar finds that the angle of depression to a ship wrack on the bottom of the ocean is 12.5°.

If a point on the ocean floor is 60 meters.

Now by using the trigonometric identity.

[tex]tan\theta = \frac{Perpendicular}{Base}[/tex]

As shown in the figure given below.

Perpendicular = CB

Base = AC = 60 meters

[tex]\theta = 12.5^{\circ}[/tex]

Put in the identity

[tex]tan\ 12.5^{\circ} = \frac{CB}{AC}[/tex]

[tex]tan\ 12.5^{\circ} = \frac{CB}{60}[/tex]

[tex]tan\ 12.5^{\circ} = 0.22[/tex]

[tex]tan\ 12.5^{\circ} = 0.22[/tex]

[tex]0.22= \frac{CB}{60}[/tex]

CB = 60 × 0.22

CB = 13.2 meters

Therefore the 13.2 meters from that point on the ocean floor to the wreck.

The distance from the point on the ocean floor directly below the ship to the shipwreck is approximately 13.3 meters.

We will use the tangent function, which relates the angle of depression to the opposite side (the distance from the point directly below the ship to the shipwreck) and the adjacent side (the depth of the ocean at the point directly below the ship).

Given:

The angle of depression [tex]\theta[/tex] is [tex]12.5^o.[/tex]

The depth of the ocean at the point directly below the ship, h, is 60 meters.

We want to find the distance from the point directly below the ship to the shipwreck, which we will call [tex]d.[/tex]

Using the tangent function :  

[tex]\[ \tan(\theta)[/tex] = [tex][\frac{\text{opposite}}{\text{adjacent}}][/tex]

[tex]\[ \tan(12.5^o) = \frac{d}{60} \][/tex]

To find d, we rearrange the equation:  [tex]\[ d = 60 \times \tan(12.5^o) \][/tex]

Now we calculate the tangent of 12.5 and multiply it by 60:[tex]\[ d = 60 \times \tan(12.5^o) \][/tex]

[tex]\[ d \approx 60 \times 0.22169\][/tex]

[tex]\[ d \approx 13.3014 \][/tex]

Therefore, the distance from the point on the ocean floor directly below the ship to the shipwreck is approximately 13.3 meters.

Answer:

g(x) = (x-3) ^2 -3

Step-by-step explanation:

f(x) = x^2

To shift down 3 units, subtract 3  ( When we move up, we add)

h(x) = x^2 -3

To shift to the right 3 units, replace x with (x-3).  I know it seems backwards, but right is minus and left is plus.

g(x) = (x-3) ^2 -3

Step-by-step explanation:

Final answer:

After applying a 40% discount to the original $62 price of the shoes and adding an 8% sales tax, the total cost of the pair of shoes is $40.18.

Explanation:

The question involves calculating the total price of a pair of shoes after a discount and adding sales tax. To find the discounted price, we take 40% off the original price of $62. To calculate 40% of $62, we multiply 62 by 0.40 (which is 40% as a decimal), giving us $24.80. We subtract this discount from the original price: $62 - $24.80 = $37.20, which is the discounted price of the shoes.

Next, calculate the sales tax on the discounted price by converting the sales tax rate from a percent to a decimal. The sales tax rate is 8%, which as a decimal is 0.08. Multiply the discounted price by the sales tax rate: $37.20 x 0.08 = $2.976, which we round to $2.98.

Finally, add the sales tax to the discounted price to find the total cost: $37.20 + $2.98 = $40.18. Therefore, the total price of the shoes, including tax, is $40.18.

Answer:

[tex]x \leq 1[/tex]

Step-by-step explanation:

Multiplying 8 by x can be written as 8x, and +6 on end:

8x + 6

Because it says 14 is no less than, the equal to or more than sign needs to be used:

[tex]8x + 6 \leq 14[/tex]

The -6 can be moved over to the other side making it a -6:

[tex]8x \leq 14 - 6[/tex]

[tex]8x \leq 8[/tex]

Simplify by dividing both sides by 8:

[tex]x \leq 1[/tex]

Which is the inequality!

Answer:

The given statement can be written as [tex]14\geq 8x+6[/tex] or [tex]x\leq 1[/tex].

Step-by-step explanation:

It is required to write the sentence as an inequality.

The given sentence is "14 is no less than 8 times a number x plus 6".

The given statement can be written as " 14 can be equal or more than 8 times a number x plus 6"

Now, in the inequality form, the statement will be,

[tex]14\geq 8x+6[/tex]

Solve the above inequality as,

[tex]14\geq 8x+6\\8\geq 8x\\1\geq x\\x\leq 1[/tex]

Therefore, the given statement can be written as [tex]14\geq 8x+6[/tex] or [tex]x\leq 1[/tex].

By simplifying and rearranging the given system of equations, we find that the ordered pair (s, t) that satisfies the system is (2, 1 + 2/3).

The system of equations given in the question is:
s/2 - 3t = -1
3t - 2s = 3.

We can begin solving this system by first multiplying the first equation by 2 to eliminate the fraction, giving us:
s - 6t = -2.

Next, we rearrange the second equation to be in terms of 's':
2s = 3t + 3.

We then substitute this into the first equation and solve for 't':
(3t + 3) - 6t = -2,
simplifying to:
-3t + 3 = -2,
leading us to t = 1 + 2/3.

Substituting 't' into the second equation to find 's', we get:
2s = 3(1 + 2/3) + 3, which simplifies to s = 2. Therefore the ordered pair (s,t) that satisfies the system of equations is (2, 1 + 2/3).

Answer:

Can not be determined.

Step-by-step explanation:

We can easily notice that the limit is x tends to infinity, whereas x is not present in the given function, we are given (1 + 1/n). So we can not evaluate the given limit for x as parameter, we must have some function of x to solve this problem.

Hence, option C is correct i.e. the limit can not be determined.

Answer:

cannot be determined

Step-by-step explanation:

If we have, [tex]\lim_{n \to \infty} {1+\frac{1}{n}}[/tex]

We plug in infinity for n directly

1/∞ =0

So when we plug in infinity for n  then 1/n becomes 0

[tex]\lim_{n \to \infty} {1+\frac{1}{n}}[/tex]

[tex] {1+\frac{1}{infinity}}[/tex]

1+ 0 = 1

In our problem , limit says x-> ∞

there is no x  term inside

[tex]\lim_{x \to \infty} {1+\frac{1}{n}}[/tex]

so we can clearly say limit cannot be determined

The quadratic function g(x) has equation [tex]g(x)=ax^2+bx+c.[/tex] Find values of a, b and c:

[tex]g(0)=2=a\cdot 0^2+b\cdot 0+c\Rightarrow c=2.[/tex]

[tex]g(2)=3=a\cdot 2^2+b\cdot 2++2\Rightarrow 4a+2b=1.[/tex]

From the last equation [tex]b=-4a[/tex] and [tex]4a-8a=1,\\ \\a=-\dfrac{1}{4},\\ \\b=1.[/tex]

The equation of the quadratic function g(x) is

[tex]g(x)=-\dfrac{1}{4}x^2+x+2.[/tex] This quadratic function determines the parabola with vertex at point (3,2). Thus,

1. The maximal value of f(x) is 4 at x=2.

2. The maximal value of g(x) is 3 at x=2.

Thus, the maximal value of f(x) is greater than the maximal value of g(x). So option B is correct.

Answer:

The answer is 25

Step-by-step explanation:

Therefore, there are 25 red flowers in Sakura’s garden1.

We know that for every 55 red flowers, there are 1010 yellow flowers.

The total number of flowers in the garden is 7575 (which includes both red and yellow flowers).

Let’s use the variable (x) to represent the number of red flowers in the garden. We can set up the following ratio:

[tex][ \frac{{\text{{Red flowers}}}}{{\text{{Total flowers}}}} = \frac{{55}}{{55 + 1010}} ][/tex]

Solving for (x):

[tex][ \frac{{\text{{Red flowers}}}}{{7575}} = \frac{{55}}{{55 + 1010}} ][/tex]

Cross-multiplying:

[tex][ 55 \cdot 7575 = 55x + 1010x ][/tex]

Simplifying:

[tex][ 7575 = 55x + 1010x ][/tex]

Combining like terms:

[tex][ 7575 = 1065x ][/tex]

Solving for (x):
