Answer 1

SOH CAH TOA

Opposite is 7

Y is the hypotenuse - longest side

So, x is the adjacent

Find y first, we've got opposite & hypotenuse

=> SOH or Sin

Sin(30) = o/h

Sin(30) = 7/h

x h

h x sin(30) = 7

÷ Sin(30)

H = 14

Pythagoras' Theorem: a^2 + b^2 = c^2

(which I've already rearranged, to find value of x)

Square root of 14^2 - 7^2 = 7 root 3.

Thus, the missing lengths should be 14 and 7 root 3.

The answer is:

y = 14

x = 7 root 3

(root => a square root)

Hope this helps!

I don’t know how to do part a

Answers

(a) The claim is made for all positive integers n, so we start at n = 1. We have

[tex]\displaystyle \sin(x) \sum_{k=1}^1 \sin(2kx) = \sin(x) \sin(2x) = \sin(1x) \sin((1+1)x)[/tex]

so the claim is true for the base case.

Suppose the claim is true for n = m, so that

[tex]\displaystyle \sin(x) \sum_{k=1}^m \sin(2kx) = \sin(mx) \sin((m+1)x)[/tex]

We want to use this to establish the identity for n = m + 1. That is, we want to prove that

[tex]\displaystyle \sin(x) \sum_{k=1}^{m+1} \sin(2kx) = \sin((m+1)x) \sin((m+2)x)[/tex]

Working with the left side, we remove the last term from the sum and we have

[tex]\displaystyle \sin(x) \sum_{k=1}^{m+1} \sin(2kx) = \sin(x) \sum_{k=1}^m \sin(2kx) + \sin(x) \sin(2(m+1)x) \\\\\\ = \sin(mx) \sin((m+1)x) + \sin(x) \sin(2(m+1))x[/tex]

Recall the angle sum identities:

[tex]\sin(x + y) = \sin(x) \cos(y) + \cos(x) \sin(y)[/tex]

[tex]\sin(x - y) = \sin(x) \cos(y) - \cos(x) \sin(y)[/tex]

[tex]\cos(x + y) = \cos(x) \cos(y) - \sin(x) \sin(y)[/tex]

[tex]\cos(x - y) = \cos(x) \cos(y) + \sin(x) \sin(y)[/tex]

Then

[tex]\sin(2(m+1)x) = 2 \sin((m+1)x) \cos((m+1)x)[/tex]

so we can remove a factor of sin((m + 1) x) :

[tex]\displaystyle \sin(x) \sum_{k=1}^{m+1} \sin(2kx) = \sin((m+1)x) \bigg(\sin(mx) + 2 \sin(x) \cos((m+1)x)\bigg)[/tex]

and we also have

[tex]2 \sin(x) \cos((m+1)x) = \sin(x+(m+1)x) + \sin(x - (m+1)x) \\\\ = \sin((m+2)x) + \sin(-mx) \\\\ = \sin((m+2)x) - \sin(mx)[/tex]

Then the sin(mx) terms cancel, and we're left with what we wanted:

[tex]\displaystyle \sin(x) \sum_{k=1}^{m+1} \sin(2kx) = \sin((m+1)x) \sin((m+2)x)[/tex]

and the induction proof is complete.

(b) From the identities mentioned earlier, one has

[tex]\sin\left(x - \dfrac\pi4\right) = \sin(x) \cos\left(\dfrac\pi4\right) - \cos(x) \sin\left(\dfrac\pi4\right) \\\\ = \dfrac{\sin(x) - \cos(x)}{\sqrt2}[/tex]

Then

[tex]\sin^2\left(x - \dfrac\pi4\right) = \dfrac{(\sin(x) - \cos(x))^2}2 \\\\ = \dfrac{\sin^2(x) - 2 \sin(x) \cos(x) + \cos^2(x)}2 \\\\ = \dfrac{1 - \sin(2x)}2[/tex]


We can then rewrite the sum as

[tex]\displaystyle \sum_{k=1}^{369} \sin^2\left(\dfrac{k\pi}5 - \dfrac\pi4\right) = \frac12 \sum_{k=1}^{369} \left(1 - \sin\left(\frac{2k\pi}5\right)\right) \\\\ = \frac12 \sum_{k=1}^{369} 1 - \frac12 \sum_{k=1}^{369} \sin\left(\frac{2k\pi}5\right)[/tex]

Recall that

[tex]\displaystyle \sum_{k=1}^n 1 = 1 + 1 + \cdots + 1 = n[/tex]

For the sum involving sine, let x = π/5. Then using the result from part (a),

[tex]\displaystyle \sin\left(\frac\pi5\right) \sum_{k=1}^{369} \sin\left(\dfrac{2k\pi}5\right) = \sin\left(\dfrac{369\pi}5\right) \sin\left(\dfrac{370\pi}5\right)[/tex]

and this sum vanishes, since sin(370π/5) = sin(74π) = 0.

It follows that

[tex]\displaystyle \sum_{k=1}^{369} \sin^2\left(\dfrac{k\pi}5 - \dfrac\pi4\right) = \frac12 \sum_{k=1}^{369} 1 = \boxed{\frac{369}2}[/tex]

Part A: what tool can help Jada find possible dimensions for the base of the block? Explain.

     I am not sure what a "tool" is by their wording, but we can use the formula for volume to solve for the base.

-> B is the base, length times width, and H is the height

V = B * H

350 in³ = B * 5 in

70 in² = B

  Answer: The base will be 70 in²

Part B: Give one pair of possible whole-number dimensions for the base.

     Since we know the base will be 70 in², we can find a possible pair of whole-number dimensions for the base.

B = L * W

70 in² = L * W

     Now we just need to find pairs of whole numbers that multiply to 70:

70 / 2 = 35

  Answer: A possible pair of whole-number dimensions for the base is 2 and 35.

The admission fee at an amusement park is $5.50 for children and $15.00 for adults. On a certain day, 283 people entered the park, and the admission fees collected totaled $2,649.00. How many children and how many adults were admitted?

Answers

Answer:

Solving steps:

Explanation:

The first bit of information is about amount, and the second part is about cost. We will make an equation for each one. Just so you know, I'm going to abbreviate "children" to c and "adults" to a .

The first equation is about amount. So since the total amount of people that came was

283

, this is the equation:

c + a = 283

The second is about cost. Children cost

$5.50 and adults cost $15.00, so we can make this equation:

=> 5.50c + 15.00a = 2,649.00

Now rearrange the first equation so that we can solve for one of the variables:

c + a = 283 → c = 283 − a

Substitute it into the second equation:

5.5c +15a = 2,649

5.5(283 − a) + 15a = 2,649

1,556.5 − 5.5a + 15a = 2,649

1,556.5 + 9.5a = 2,649

9.5a = 1,092.5

a = 115

115 adults came.

Now substitute the value of into this equation and solve for c

.c = 283 - a

c = 283 - 115

c = 168

168 children came.

The square is 5*4=20. and the smaller triangles on the side are 1*5*1/2=2.5, and there are 2 traingles so 2.5*2= 5. So 5+20+12=37.

Part (a)

The domain is the set of allowed x inputs of a function.

The graph shows that x = 0 is not allowed because of the vertical asymptote located here. It seems like any other x value is fine though.

Domain: set of all real numbers but [tex]x \ne 0[/tex]

To write this in interval notation, we can say [tex](-\infty, 0) \cup (0, \infty)[/tex] which is the result of poking a hole at 0 on the real number line.

--------------

The range deals with the y values. The graph makes it seem like it stretches on forever in both up and down directions. If this is the case, then the range is the set of all real numbers.

Range: Set of all real numbers

In interval notation, we would say [tex](-\infty, \infty)[/tex] which is almost identical to the interval notation of the domain, except this time of course we aren't poking at hole at 0.

Part (b)

The x intercepts are x = -4 and x = 4

We can compact that to the notation [tex]x = \pm 4[/tex]

These are the locations where the blue hyperbolic curve crosses the x axis.

=======================================================

Part (c)

Answer: There aren't any horizontal asymptotes in this graph.

Reason: The presence of an oblique asymptote cancels out any potential for a horizontal asymptote.

=======================================================

Part (d)

The vertical asymptote is located at x = 0, so the equation of the vertical asymptote is naturally x = 0. Every point on the vertical dashed line has an x coordinate of zero. The y coordinate can be anything you want.

Answer: x = 0 is the vertical asymptote

=======================================================

Part (e)

The oblique or slant asymptote is the diagonal dashed line.

It goes through (0,0) and (2,6)

The equation of the line through those points is y = 3x

If you were to zoom out on the graph (if possible), then you should notice the branches of the hyperbola stretch forever upward but they slowly should approach the "fencing" that is y = 3x. The same goes for the vertical asymptote as well of course.

Answer:  Oblique asymptote is y = 3x
