1/(cot^2 (x)) - 1/(cos^2 (x))

Answer:

y = -1/2x + 5

Step-by-step explanation:

x + 2y = 10

Step 1: subtract x from both sides.

you will get:    2y = -x + 10

Step 2: get the y by itself, you can do this by dividing 2 by both sides.

=  2y = -x + 10

     y = -1/2x +10/2

Then, 10/2 simplifies to 5.

So, your answer is: y = -1/2x + 5

Step-by-step explanation:

Length and width of rectangular rose garden is 15 and 5 feet

Given that;

Perimeter of rectangular rose garden = 40 feet

Length of the garden = 5 more  than twice the width

Find:

Dimensions of the rose garden

Computation:

Assume;

Width of garden = a

So,

Length of the garden = 2a + 5

Perimeter of rectangle = 2[l + b]

40 = 2[2a + 5 + a]

40 = 2[3a + 5]

40 = 6a + 10

6a = 40 - 10

6a = 30

a = 5

Width of garden = 5 feet

Length of the garden = 2a + 5

Length of the garden = 2(5) + 5

Length of the garden = 15 feet

The number of sides of the regular polygon is 26

The formula for calculating the exterior angle of a regular polygon is expressed as:

Exterior angle of a polygon = 360 ÷ number of sides.

Given the following:

Exterior angle of a regular polygon = 13.8 degrees

Required

Number of sides

Substitute the given parameters into the formula as shown:

Exterior angle of a polygon = 360/13.8

Exterior angle of a polygon = 26.08

This means that the number of sides of the regular polygon is 26

Graph

Answer: 20

Step-by-step explanation:

Jacob's grandma peeled 4 times as many potatoes as he did, so if she peeled  16, you would divide 16 by 4 and conclude that Jacob peeled 4 potatoes. Then, you would add the 4 potatoes that he peeled to her 16. Hope this helps!

Jacob and his grandmother both peeled 20 potatoes.

A ratio is a numerical comparison of two numbers. A ratio represents the proportion of one object to another.

Given, Jacob's grandmother peeled four times as many potatoes as he did, therefore if she peeled 16, divide 16 by four to get that Jacob peeled four potatoes. Then you'd add the four peeled potatoes to her 16.

potato peeled by Jacob's grandmother = 16

potato peeled by Jacob = 4

Total potatoes peeled = 16 + 4 = 20

Therefore both Jacob and his grandmother peeled the sum of 20 potatoes together.

Step-by-step explanation:

Answer:

[tex]m = \frac{y_ 2 - y_ 1}{x_ 2 - x_ 1} = \frac{2 - 3}{6 - 8} \\ m = \frac{ - 1}{ - 2} \\ \therefore \: m = \frac{1}{2} [/tex]

-3x + 2b > 8

---Subtract 2b from both sides

-3x > -2b + 8

---Divide both sides by -3. Remember that when multiplying or dividing by a negative in inequalities, we flip the inequality sign.

x < (-2b + 8) / -3

(Option 1)
