From the equilateral triangle, The bearing of L from N is 120°.

All interior angles are equal to 60°. We are given the bearing of M from L as 103°. To find the bearing of L from N, we first need to find the bearing of N from L.

The interior angle at L is 60°, and since the bearing of M from L is 103°, the bearing of N from L is 103° + 60° = 163°.

Now, we need to find the bearing of L from N. Since the angle at N is also 60°, and we know that bearings are measured clockwise, the bearing of L from N will be 180° - 60° = 120°.

So, the bearing of L from N is 120°.

The given statement "the understanding of percent requires no new skills or concepts beyond those used in mastering fractions, decimals, ratios, and proportions." is generally true.

Understanding percentages involves converting a proportion or ratio to a fraction with a denominator of 100. For example, 75% is equivalent to 75/100 or 3/4. Converting between percentages, fractions, and decimals requires a solid understanding of the relationships between these different forms of numbers, which are based on the same underlying concepts of part-whole relationships.

To convert a percentage to a decimal, you can divide by 100 or move the decimal point two places to the left. To convert a decimal to a percentage, you can multiply by 100 or move the decimal point two places to the right. To convert a fraction to a percentage, you can first convert it to a decimal and then multiply by 100.

Understanding percentages is also important for many real-world applications, such as calculating discounts, interest rates, and taxes. It is therefore important to have a strong foundation in fractions, decimals, ratios, and proportions in order to fully grasp the concept of percentages.

It takes the unpowered raft 192 hours to travel the same distance between Pier A and Pier B.

Let's assume the distance between Pier A and Pier B is D.

When the motorboat is going downstream, it benefits from the current, so its effective speed is increased.

Let's say the speed of the motorboat in still water is S.

The speed of the current is C.

Therefore, the motorboat's speed downstream is S + C.

When the motorboat is going upstream, it has to overcome the current, so its effective speed is decreased.

The speed of the motorboat upstream is S - C.

We are given that the motorboat takes 32 hours to go downstream and 48 hours to return upstream.

Downstream speed: S + C

Downstream time: 32 hours

Distance = Speed × Time

D = (S + C) × 32

Upstream speed: S - C

Upstream time: 48 hours

D = (S - C) × 48

Since the distance (D) is the same in both cases, we can equate the two equations:

(S + C) × 32 = (S - C) × 48

32S + 32C = 48S - 48C

16S = 80C

S = 5C

We know that the raft is unpowered, so its speed is equal to the speed of the current (C).

Therefore, the speed of the unpowered raft is C.

Time = Distance / Speed

Time = D / C

Since D = (S + C) × 32

we can substitute the value of S:

Time = [(5C) + C] × 32 / C

Time = 6C × 32 / C

Time = 192

The closest answer is (d) 3185. To determine the magnitude of the moment about the y-axis, we need to first calculate the moment vector by taking the cross product of the position vector and the force vector:

r x F = <4, -6, 4> x <300, 200, ?> = <(-6*?), (-4*?), (-1800-1200)> =

Since we only care about the magnitude of the moment, we can use the formula:

|τ| = |r x F| = √( ?^2 + ?^2 + (-3000)^2 )

We can solve for the missing components by using the fact that the cross product is orthogonal to both r and F, so the dot product between them must be zero:

4*? + (-6)*? + 4*(300) = 0

Simplifying this equation gives:

4*? - 6*? + 1200 = 0

-2*? = -1200

? = 600

Substituting this value into the previous formula gives:

|τ| = √( (-6*600)^2 + (-4*600)^2 + (-3000)^2 ) = √(2160000 + 1440000 + 9000000) = √12600000 = 3549.83

Q2. The value of lim f(x) as x approaches infinity does not exist.

Q1. To find the value of lim f(x) as x approaches 17, we substitute 17 for x in the expression f(x) = x(2-x)/(sqr(11x)+1). This gives us:

lim f(x) = lim [x(2-x)/(sqr(11x)+1)] as x approaches 17

= 17(2-17)/(sqr(11*17)+1)

= -15/2(187)+1

Q2. To find the value of lim f(x) as x approaches infinity, we can use L'Hopital's rule. Taking the derivative of the numerator and denominator with respect to x, we get:

lim f(x) = lim [(2-x)/(2sqr(11x)+x)] as x approaches infinity

= lim [-(1)/(22sqr(11x)+1)] as x approaches infinity (by applying L'Hopital's rule again)

As x approaches infinity, the denominator approaches infinity, so the limit of the expression is 0. Therefore, the limit of f(x) as x approaches infinity does not exist.

a. 68 ÷ 17 = 4

c. 357 ÷ 17 = 21

The numbers that are divisible by 17 are 68 (a) and 357 (c).

To check whether a number is divisible by 17 or not, we can use the following rule:

Take the last digit of the number and multiply it by 5. Subtract the product from the remaining digits. If the result is divisible by 17, then the original number is also divisible by 17.

Let's apply this rule to the given numbers:

a. 68: The last digit is 8. 5 x 8 = 40. Subtracting 40 from 6 gives us -34. -34 is divisible by 17, so 68 is also divisible by 17.

b. 84: The last digit is 4. 5 x 4 = 20. Subtracting 20 from 8 gives us -12. -12 is not divisible by 17, so 84 is not divisible by 17.

c. 357: The last digit is 7. 5 x 7 = 35. Subtracting 35 from 35 gives us 0. 0 is divisible by 17, so 357 is also divisible by 17.

d. 1001: The last digit is 1. 5 x 1 = 5. Subtracting 5 from 100 gives us 95. 95 is not divisible by 17, so 1001 is not divisible by 17.

Therefore, the numbers that are divisible by 17 are 68 (a) and 357 (c), and the numbers that are not divisible by 17 are 84 (b) and 1001 (d).

Q = [1/√6 1/√2 1/√3; 1/√6 0 -2/√15; 2/√6 -1/√2 1/√15]

and

A = [1 4; 1 0; 0 1]

We can compute [tex]Q^T[/tex] as:

[tex]Q^T[/tex] = [1/√6 1/√6 2/√6; 1/√2 0 -1/√2; 1/√3 -2/√15 1/√15]

Multiplying [tex]Q^T[/tex] and A, we get:

[tex]Q^T A[/tex] = [1/√6 1/√6 2/√6; 1/√2 0 -1/√2; 1/√3 -2/√15 1/√15] [1 4; 1 0; 0 1] = [√6 5/√6; 0 2/√15; 0 0]

Therefore, R = [tex]Q^T A[/tex] = [√6 5/√6; 0 2/√15; 0 0].

So we have A = QR, where Q is the given matrix and R is the upper triangular matrix we just computed.
