I just need help with #1

Given that,

θ € 4th quadrant

3π/2 < θ < 2π

sin θ = - 1/2

sin²θ + cos²θ = 1

[ -1/2] ² + cos²θ = 1

1/4 + cos²θ = 1

cos²θ = 1 - 1/4

cos²θ = 4 - 1 / 4

cos²θ = 3/4

As,

θ € 4th quadrant = cos θ > 0

cosθ = √3/2

tan θ = 1/2 ÷ √3/2

tan θ = - 1/√3

cosec θ = 1/sin θ = -2

sec θ = 1/cos θ = 2√3

Answer:

3(5-2x) = 2(4x=3)

= 15-6x = 8x=6

= 15-6x = 8x-6

= 15-6 = 8x+6x

= 9 = 14x

therefore, x=9/14

Answer:

A quadrilateral's interior angles have a sum of 360°.

Given that we have 85°, 100°, and 90°(the right angle), and an unknown angle.

We can add these angles plus the unknown angle to equal a total of 360°.

85 + 100 + 90 + x(our unknown missing angle) = 360

simplify

275 + x = 360

Isolate x by subtract 275 from both sides;

-275       -275

x = 85, ∠1 = 85°

We can also double check:-

85 + 100 + 90 + 85 = 360

360 = 360 which is correct.

Answer:

Your answer is 4 Years!

Answer: 4 Years

Step-by-step explanation: Just to confirm the other person it is 4 years!

1)

First 2 triangles can be proven similar but are not necessarily congruent since you can't from them using the side-angle-side or angle-side-angle or triple side rule.

2)

ONM = QNP since they are vertically opposite angles.

MON = NPQ given equal on the figure

ON=NP given

The two triangles are proven congruent using the angle-side-angle property.

3)

Last 2 pairs cannot be proven congruent as there is not enough info.

Answer:

k=0 or 4

Step-by-step explanation:

[tex]y=x^2+(k+4)x+3k+4\\=x^2+(k+4)x+(\frac{x+4}{2})^2 +3k+4-(\frac{x+4}{2})^2\\=(x+\frac{x+4}{2})^2+3k+4-(\frac{x+4}{2})^2\\[/tex]

so the vertex is at

[tex](-\frac{k + 4}{2}, 3k+4-(\frac{x+4}{2})^2)[/tex]

The vertex lies in the x-axis, so

[tex]3k+4-(\frac{k+4}{2})^2 = 0\\4(3k+4)-(k+4)^2=0\\12k+16-k^2-8k-16=0\\-k^2+4k=0\\-k(k-4)=0\\k-0, 4[/tex]

Domain is the x-intercept(first number) for example if I were told to find the domain in (1,3)(4,7)(8,9) the domain would be 1,4, and 8 because they're the x-factors and then plotting a point, the x-factors come first.

Range is the y-factors(second number) and given an example above, the ranges would be 3,7, and 9 because when plotting, they are the second number.

You can tell if it is a function or not if the X-factors repeat. For example, the first one is NOT a function because the 2 repeats for the x-factor. Number 2 IS a function because the x-factor doesn't repeat.

Sorry if this doesn't make sense, that's the best way I can explain!

Answer:

9

Step-by-step explanation:

Should be correct.

Answer:

x=7

Step-by-step explanation:

Since the angles are the same, the sides have to be the same length

x=7

Answer: x = 7

We see that the angles in the triangle are the same length. So, they have the same value as each other.

x = 7

Using the normal probability distribution and the central limit theorem, it is found that there is a 0.0207 = 2.07% probability that the sample proportion of baseball players will be greater than 63%.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, we have that:

The mean and the standard error are given by:

[tex]\mu = p = 0.59[/tex]

[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.59(0.41)}{632}} = 0.0196[/tex]

The probability that the sample proportion of baseball players will be greater than 63% is one subtracted by the p-value of Z when X = 0.63, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.63 - 0.59}{0.0196}[/tex]

[tex]Z = 2.04[/tex]

[tex]Z = 2.04[/tex] has a p-value of 0.9793.

1 - 0.9793 = 0.0207.

0.0207 = 2.07% probability that the sample proportion of baseball players will be greater than 63%.

Now we need to subtract the commission that Cynthia is paying her broker. $88 per $1000 means Cynthia owes her broker 17*88=$1496. Now we subtract that from 17342 to get $15,846.

[tex]\sqrt{(7 /3)}[/tex]

Find the value of 7 divided by 3. It is 2, remainder 3 because...

3 goes into 7, 2 times.

Now, square root the value of the division. In short words, find factors.

1/3 is a reduction of 2/3, that means it could be put as 2/3 if you substitute for this situation.

The opposite of the number, -7, is its reciprocal, which is: 7.

The opposite of a number is its reciprocal or the value on the number line that would occupy the same distance from zero in the opposite direction.

For example, opposite of b is -b.

The reciprocal of -7 is 7. Therefore, the opposite of the number, -7 is: 7.

Answer:

  $381,000 loss

Step-by-step explanation:

Profit is the difference between revenue and cost. Cost is the sum of fixed cost and variable cost. Revenue is the product of selling price and quantity sold.

__

If we assume the company only manufactures as many sneakers as it sells, then the profit can be found from ...

  R(x) = 75x . . . . . revenue from selling x sneakers

  C(x) = 1,500,000 +0.40x . . . . . . cost to manufacture x sneakers

  P(x) = R(x) -C(x) . . . . . profit from making and selling x sneakers

  P(x) = 75x -(1,500,000 +0.40x)

  P(x) = 74.60x -1,500,000 . . . . . profit from x sneakers

  P(15000) = 74.60·15,000 -1,500,000 = 1,119,000 -1,500,000

  P(15000) = -381,000

The total loss from making and selling 15,000 sneakers is $381,000.
