Trigonometric Identities

If the trigonometric function value of an angle is given, we can find the rest of the trigonometric values of the angle by using one or more of the fundamental identities.

To solve this problem, we need to use the following identities:

[tex]\displaystyle \cot^2\theta=\csc^2\theta-1[/tex]

[tex]\displaystyle \tan\theta=\frac{1}{\cot\theta}[/tex]

Since we are given:

[tex]\displaystyle \csc\theta=2\sqrt{3}[/tex]

And the angle is in the first quadrant, calculate the cotangent:

[tex]\displaystyle \cot^2\theta=(2\sqrt{3})^2-1[/tex]

[tex]\displaystyle \cot^2\theta=4*3-1=11[/tex]

[tex]\displaystyle \cot\theta=\sqrt{11}[/tex]

The tangent is:

[tex]\displaystyle \tan\theta=\frac{1}{\sqrt{11}}[/tex]

Rationalizing the denominator:

[tex]\displaystyle \tan\theta=\frac{1}{\sqrt{11}}*\frac{\sqrt{11}}{\sqrt{11}}[/tex]

[tex]\boxed{\displaystyle \tan\theta=\frac{\sqrt{11}}{11}}[/tex]

Answer:

the correct graph is b for this problem

Given:

The series is

[tex]2x+2x^2+2x^3+...+2x^n[/tex]

To find:

Whether the given series is arithmetic, geometric, both, or neither.

Solution:

We have,

[tex]2x+2x^2+2x^3+...+2x^n[/tex]

Difference between consecutive terms are:

[tex]d_1=a_2-a_1[/tex]

[tex]d_1=2x^2-2x[/tex]

[tex]d_1=2x(x-1)[/tex]

And,

[tex]d_2=a_3-a_2[/tex]

[tex]d_2=2x^3-2x^2[/tex]

[tex]d_2=2x^2(x-1)[/tex]

Here, [tex]d_1\neq d_2[/tex].

So, the given series is not an arithmetic series.

Ratio between consecutive terms are:

[tex]r_1=\dfrac{a_2}{a_1}[/tex]

[tex]r_1=\dfrac{2x^2}{2x}[/tex]

[tex]r_1=x[/tex]

And,

[tex]r_2=\dfrac{a_3}{a_2}[/tex]

[tex]r_2=\dfrac{2x^3}{2x^2}[/tex]

[tex]r_2=x[/tex]

Similarly upto last pair of consecutive terms.

[tex]r_{n-1}=\dfrac{a_n}{a_{n-1}}[/tex]

[tex]r_{n-1}=\dfrac{2x^n}{2x^{n-1}}[/tex]

[tex]r_{n-1}=x[/tex]

Since, [tex]r_1=r_2=...=r_{n-1}[/tex], so the given series have a common ratio.

Therefore, it is a geometric series.

Answer:

Option.B

There is a negative correlation in the data set

The correlation shown in the data is negative correlation.

Scatterplots are the plotting of set of points on a vertical axis and an horizontal axis. The shows the correlation extent between the numbers of the observed quantities.

Positive correlation is defined as the relationship where the value of y increases with the increase in the value of x.

Negative correlation is defined as the relationship where the value of y decreases with the decrease in the value of x.

Here the points are in such a way that the value of y decreases with increase in x.

So it is negative correlation.

Hence the correct answer is negative correlation.

Answer:

The required equation is:

0.23x = 52

Hence, option A is true.

Step-by-step explanation:

Given

Let 'x' be the initial depth

The snow is now 52 inches deep and it is a 77% decrease.

Let the initial 'x' depth be represented as 100%.

x → 100%

Given the current 52 inches is a 77% decrease. So, we need to decrease the 77/100 or 0.77 from the initial depth, so

[100% - 77%] of x = 52

[100/100 - 77/100] × x = 52

[1 - 0.77] × x = 52

0.23x = 52

Therefore, the required equation is:

0.23x = 52

Hence, option A is true.

-3/4

Step-by-step explanation:

Answer:

x= -3/4

Step by Step explanation:

Step 1: Simplify both sides of the equation.

−8(4x+6)=−24

(−8)(4x)+(−8)(6)=−24     (Distribute)

−32x+−48=−24

−32x−48=−24

Step 2: Add 48 to both sides.

−32x−48+48=−24+48

−32x=24

Step 3: Divide both sides by -32.

-32x/-32 =24/-32

Answer:

t = 33 seconds

It is the amount of time when the temperature of the body will rise from 100 to fatal 104 in the absence of sweat.

Step-by-step explanation:

weight of the farmer = 176 lb

Sweating = 1 litre per hour

60% of above sweating is evaporated by the latent heat from farmers body.

Temperature outside = 104

Temperature of the Farmer = 100

Time to rise the temperature 4 degrees = ?

We need to use the specific heat formula to calculate the time to rise the temperature of the body of farmer.

Before, that let's convert weight of the farmer in Kg

W = 176 lb

1 lb = 0.453592 kg

176 lb = 79.8 kg

w = mg

g = 10

mass = m = 79.8/10

mass = 7.98 kg

Q = mc∆T

c = specific heat of water =  4,186

∆T  = Temperature Change = 104-100

∆T  = 4

Q = 7.98 x 4186 x 4

Q = 133617

t = Q/P

Power of Sun's Heat = 3.846×1026

t = 33 seconds

It is the amount of time when the temperature of the body will rise from 100 to fatal 104 in the absence of sweat.

I am a little confused with the "all trees $42" answer but if that means she could buy that size for $42 then I believe that is the answer that should be chosen because for question B, 6 per ft. would likely be 48 because 6x8 = 48, and I don't believe half ft would be $3.

Answer:

4x3=3x4

Step-by-step explanation:

Answer:

a. The length of the box = (40 - 2·x) cm

The height of the box = x cm

The width of the box = (25 - 2·x) cm

b. The formula for the volume of the box as a function of x is 4·x³ - 130·x² + 1000·x

c. The value of x that would maximize the volume of the box is x = 5 cm

d. The largest volume of the box is 2250 cm³

Step-by-step explanation:

a. The given parameters are;

The length of the cardboard = 40 cm

The width of the cardboard = 25 cm

The length of the box = (40 - 2·x) cm

The height of the box = x cm

The width of the box = (25 - 2·x) cm

b. The formula for the volume of the box = The area of the base of the box × Height of the box

The area of the base of the box =  (40 - 2·x) × (25 - 2·x) = 1000 - 80·x - 50·x + 4·x²

∴ The area of the base of the box = 4·x² - 130·x + 1000

The height of the box = x

The volume of the box = (4·x² - 130·x + 1000) × x = 4·x³ - 130·x² + 1000·x

The volume of the box in terms of x, V = 4·x³ - 130·x² + 1000·x

c. At the extremum point, dV/dx = 12·x² - 260·x + 1000 = 0

x = (260 ± √((-260)² - 4 × 12 × 1000))/(2 × 12)

x = (260 ± 140)/(24)

x = 5 or x = 16.[tex]\bar 6[/tex]

At x = 5, the volume of the box is V = 4×5³ - 130×5² + 1000×5 = 2250

The volume of the box is V = 2250 cm³

At x = 16.67, the volume is 4×16.67³ - 130×16.67² + 1000×16.67 = -925.[tex]\overline {925}[/tex]cm³

Therefore, the value of x that would maximize the volume of the box is x = 5 cm

d. The largest volume of the box is 4×(5 cm)³ - 130×(5 cm)² + 1000×(5 cm) = 2250 cm³.

945945945 minutes

There are 945 minutes will he read in all during the two months.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Oliver read for 450 minutes this month.

And, His goal is to read for 10% more minutes next month.

Now,

Since, His goal is to read for 10% more minutes next month.

Hence, The extra minutes for next month = 10% of 450 minutes

                                                                 = 10/100 × 450

                                                                 = 45 minutes

Thus, The total minutes to read in all during the two months is,

⇒ 450 + (450 + 45) minutes

⇒ 450 + 495 minutes

⇒ 945 minutes
