Suppose cot(theta) = 5/12, where pi < theta < 3pi/2. What is sin(theta)?

A. -12/13
B. -5/13
C. 5/12
D. 12/13

Answers

Answer 1

Answer:

- 12 /13

Step-by-step explanation:

Given that:

Cot(θ) = 5 /12 ;

Recall ; cot θ = 1 / tan θ ; tan θ = sin θ / cos θ

Hence ;

tan θ = 1 / cot θ

tan θ = 1 ÷ (5 / 12)

tan θ = 1 * 12 /5 = 12/5

Tan θ = opposite / Adjacent = 12 /5

Sin θ = opposite / hypotenus

Hypotenus = √(opposite² + adjacent²)

Hypotenus = √12² + 5²

Hypotenus = √(144 + 25)

Hypotenus = √169

Hypotenus = 13

Hence,

Sin θ = opposite / hypotenus = 12 / 13

pi < theta < 3pi/2 lies in the 3rd quadrant ; SinΘ will be negative ;

Sin θ = - 12 /13

Samantha is making flower arrangements. She has 32 roses and 96 daisies. If she wants to make all the arrangements identical and have no flowers left over, how many daisies will be in each flower arrangement?

Answers

Answer:

3 daisies.

Step-by-step explanation:

Given that,

Samantha has 32 roses and 96 daisies.

She wants to make all the arrangements identical and have no flowers left over. We need to find the no of daisies in each flower arrangement.

For this, we need to first find the HCF of 32 and 96.

The factors of 32 are: 1, 2, 4, 8, 16, 32

The factors of 96 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96

HCF = 32

No of daisies = 96/32 = 3

Hence, there are 3 daisies in each flower arrangement.

What is a transversal?

We know when a transversal intersects two parallel lines at two distinct points,

Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.

We know vertically opposite angles are equal, and we also know that sum of all the interior angles of a triangle is equal to 180°.

∴ 47° + (2x + 13)° + (5y - 23)° = 180°.

47° + 13° - 23° + 2x + 5y = 180°.

2x + 5y = 143°...(i).

Now, We also know that when parallel lines are intersected by a transversal pair of alternate angles are equal and the sum of two adjacent angles is equal to 180°.

∴ 3x + (5y - 23)° = 180°.

3x + 5y = 157°...(ii)

Now subtracting eqn(i) from eqn(ii) we get x = 14°, and substituting the value of x in any of the equations we y = 23°.

− 3/4 is a rational number, but not an integer. Explain why below.

Answers

A rational number is any number that can be expressed as a fraction. An integer is a whole number. -3/4 is a fraction but not a whole number, so it is rational but not an integer.

− 3/4 is not an integer but a a rational number.

Why is this correct?

A rational number is simply a number that can be written as a fraction with both the numerator and denominator being integers (where the denominator's not zero). For instance lets consider 3/4 as an example. It can be expressed as the fraction 3/4, where 3 and 4 are both integers.

On the hand an integer is a number that is not, in the form of a fraction. In the case of 3/4 it cannot be classified as an integer since it represents a fraction, than a whole number.

Sasha sells T-shirts. Each day she earns a set amount, plus a commission.



Assume Sasha sells 24 T-Shirts in one day. How much would she earn that day?

Answers

Answer:

137$

Step-by-step explanation:

Let the slope of the equation be

[tex]m=\dfrac{\Delta y}{\Delta x}[/tex]

where y = Total pay

x = T-shirts sold

Take any two values of x and corresponding y value

[tex]m=\dfrac{71-68}{2-1}\\\Rightarrow m=3[/tex]

The equation will be

[tex]y=mx+b[/tex]

Finding b

[tex]68=3\times 1+b\\\Rightarrow b=68-3\\\Rightarrow b=65[/tex]

The equation is

[tex]y=3x+65[/tex]

Now sasha sells 24 shirts [tex]x=24[/tex]

[tex]y=3\times 24+65\\\Rightarrow y=137[/tex]

Sasha would earn 137$ on that day.

The 9th and the 12th term of an arithmetic progression are 50 and 65 respectively find the sum of the first 70 terms

Answers

Answer:

Sum of the first 70 terms is 12,775

Step-by-step explanation:

For the 9th term, the formula is;

a + 8d = 50

For the 12th

a + 11d = 65

Subtract this from the equation above;

3d = 15

d = 15/3 = 5

To get a, we have a + 8(5) = 50

a = 10

The 70th term

will be

a + 69d

= 10 + 69(5)

= 355

Sum of the first 70

= n/2(a + L)

= 70/2( 10 + 355)

= 35 * 365 = 12,775
