Answer:[tex]\frac{-5}{4}, \frac{3}{4}[/tex]

Step-by-step explanation:

Given

[tex]\theta[/tex] is in the third quadrant and

[tex]\Rightarrow \cos \theta=\frac{-3}{5}[/tex]

tan and cot is positive in the third quadrant and the rest are negative

using identity

[tex]\sin^2 \theta+\cos^2 \theta=1\\\Rightarrow \sin \theta=-\sqrt{1-\cos^2 \theta}\\\Rightarrow \sin \theta =-\sqrt{1-(-\frac{3}{5}^2)}\\\Rightarrow \sin \theta =-\frac{4}{5}\\\Rightarrow\text{cosec} \theta=-\frac{5}{4}\\\Rightarrow \cot \theta=\frac{\cos \theta}{\sin \theta}=\frac{\frac{-3}{5}}{\frac{-4}{5}}=\frac{3}{4}[/tex]

Hey store buys a jacket for $20 then sells it to customers for 80% more than what is the selling price of the jacket

Answers

Given:

Cost of a jacket = $20

Then sells it to customers for 80% more than.

To find:

The selling price of the jacket

Solution:

We have,

Cost of a jacket = $20

Selling price = cost + 80% of cost

                     = [tex]20+\dfrac{80}{100}\times 20[/tex]

                     = [tex]20+\dfrac{8}{1}\times 2[/tex]

                     = [tex]20+16[/tex]

                     = [tex]36[/tex]

Therefore, the selling price of the jacket is $20.

The simplification of expression [tex]\frac{x^{6}y^{4} }{xy^{2} }[/tex]  is  [tex]x^{5}y^{2}[/tex].

SimplificationWhat is simplification?

Finding a solution to a complicated calculation that may involve square roots, cube roots, plus and minus integers, division, multiplication, and other mathematical operations is typically referred to as simplification.

What is exponent?

The number of times a number has been multiplied by itself is referred to as an exponent.

Rule of exponents:

Rule of the product of powers: When multiplying like bases, add the powers together.

Rule of the quotient of powers: When splitting like bases, take the powers out.

Solution for the expression:

The expression is given as

[tex]\frac{x^{6}y^{4} }{xy^{2} }[/tex]

Applying multiplication and product rule, one power of x will be reduced and 2 power of y will be reduced.

Thus, the the simplified equation will become [tex]x^{5}y^{2}[/tex].

A rectangular garden has an area of 60 squared feet. The garden is 4 feet longer than it is wide. Which equation can be used to determine the length and width of the garden?

Answers

Answer: See explanation

Step-by-step explanation:

Let the width be x

Then, the length will be x+4

Area = Length × Width

Therefore,

x × (x+4) = 60

x² + 4x = 60

x² + 4x - 60 = 0

x² + 10x - 6x - 60 = 0

x(x + 10) - 6(x + 10) = 0

(x - 6)(x + 10) = 0

x - 6 = 0

x = 6

The width is 6feet

Length = 6+4 = 10 feet

A right triangle has a leg that measures 15 ft and the hypotenuse measures 24 ft. What would the
length of the missing leg be to the nearest whole number?

Answers

Answer:

x=19

Step-by-step explanation:

First, you place the numbers in place of the variables in their relative positions using the pythagorean theorem:

[tex]15^{2} +x^{2}=24^{2}[/tex]

Then you square the numbers that you currently have:

[tex]225+x^{2}=576[/tex]

Then subtract 225 from both sides to isolate the x:

[tex]x^{2} =576-225[/tex]

This gives you the equation:

[tex]x^{2} =351[/tex]

Then take the square root of both sides which gives you:

[tex]x=18.7349939952[/tex]

Then round to the nearest whole number which gives you x=19
