How many solutions does the equation (2 sin x + 1)(sin x – 1) = 0 have over the interval 0 ≤ x < 2π?
a. 1
b. 2
c. 3
d. 4

Answer:

1080 degrees

Step-by-step explanation:

The sum of the interior angles of any polygon is:

Sum = (n - 2) * 180

Where n represents the number of vertices of the polygon

This polygon has 8 vertices so:

(8-2) * 180 = 6*180 = 1080 degrees

Step-by-step explanation:

The only way I know is to divide the centimeters by 30.48

Answer:

1

Step-by-step explanation:

The vertex is at (0,0)

and the directrix is y = -1

so the distance is 1

Answer:

x+ y = -7, or

y = -x-7 …(1)

xy = -60, or

y = -60/x …(2)

Equate (1) and (2)

-x-7 = -60/x, or

x+7 = 60/x, or

x^2+7x-60=0

(x+12)(x-5) = 0

x = -12 or +5 and y = +5 or -12, respectively.

Answer:

0

Step-by-step explanation:

All the numbers equal each other out.

for example:

-6+6=0

so if you have -6+-5+-4+-3+-2+-1+0+1+2+3+4+5+6, all of the numbers equal each other out.

THE ANSWER TO YOUR QUESTION IS B or 28/35 and 10/35

Step-by-step explanation:

we are going to focus on the 2/7 and the 10/35.

2 goes into 10 5 times. so 5 times 7 is 35. So that is true, the rule is what you do to the top you do to the bottom.

so basiclly 5 times 2 is 10 and 5 times 7 (from 2/7) is 35. so we then get 10/35.

now we will move onto the 25/35 and 4/5.

again 5 goes into 35 7 times. so 5 times 7 is 35. so we figured out how many times 5 goes into the denominator.

Now we have to figure out how many times 4 goes into 28. We got the four from the 4/5. so 28 divided by 4 is 7!!!

let me know if you dont get it im am always bord and eager to help others!!

Answer:

Trees contribute to their environment by providing oxygen, improving air quality, climate amelioration, conserving water, preserving soil, and supporting wildlife. During the process of photosynthesis, trees take in carbon dioxide and produce the oxygen we breathe.

Trees give off oxygen that we need to breathe. Trees reduce the amount of stormwater runoff, which reduces erosion and pollution in our waterways and may reduce the effects of flooding. Many species of wildlife depend on trees for their habitat. Trees provide food, protection, and homes for many birds and mammals.

They give us clean water to drink, air to breathe, shade, and food to humans, animals, and plants. They provide habitats for numerous species of fauna and flora, firewood for cooking and heat, materials for buildings and places of spiritual, cultural, and recreational importance.

Answer:

y=-2/3-2

Step-by-step explanation:

Answer:

y = 4/3x - 10

Step-by-step explanation:

Slope: 4/3

y-intercept: -2 - (4/3)(6) = -2 - 8 = -10

The equation of the line that passes through the given point will be equal to y = (4/3)x - 4.

It is possible to determine a line's direction and steepness by looking at its slope. Finding the slope between lines inside a coordinate plane can aid in anticipating if the lines are perpendicular, parallel, or none at all without physically using a compass.

As per the given data in the question,

The given point is (6, -2)

Slope, m = 4/3

Use the equation of the point-slope form,

(y - y₁) = m (x - x₁)

y + 2 = 4/3(x - 6)

Also, it can be written as,

3y + 6 = 4x - 6

3y = 4x - 12

y = (4/3)x - 4

Answer:

Mia and her family went to dinner, and the bill, including tax, came to $54.65. Mia suggested giving the server a gratuity of about 20 percent of the bill.

If they give a gratuity of 20 percent, what would be the tip rounded to the nearest dollar?

✔ $11

If they give a gratuity of 20 percent, rounded to the nearest dollar, what is the total cost of the dinner, including the tip?

✔ $65.65

Step-by-step explanation:

The amount of tip was $11 and the total cost of dinner including tip was $66.

Given that, at the dinner Mia and her family get the bill including tax, of $54.65.

Mia wants to give the server a gratuity of about 20 percent of the bill.

We need to find the amount of tip given and total cost of dinner including the tip.

a) To calculate the tip, we need to find 20 percent of the bill amount, which is $54.65.

20 percent of $54.65 = 0.20 × $54.65

= $10.93.

Rounding this amount to the nearest dollar, the tip would be $11.

b) To find the total cost of the dinner, including the tip, we need to add the tip amount to the bill.

Bill amount: $54.65

Tip amount: $11

Total cost of dinner = $54.65 + $11 = $65.65.

Rounding this total cost to the nearest dollar, the total cost of the dinner, including the tip, would be $66.

Hence the total cost of the dinner, including the $11 tip, was $66.

Answer:

Step by step explanation:

A line is intersecting Point (0,2) and (1,2)

(x1,y1) = (0,2)

(x2,y2) = (1,2)

(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)

(y - 2)/(2 - 2) = (x - 0)/(1 - 0)

(y - 2)/0 = x/1

Answer: y = (1/2)x + 1/2

Step-by-step explanation:

The standard form of an equation for a straight line is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).

We can calculate the slope from any two points.  I'll pick (-3,-1) and (3,2).

Slope is Rise/Run, where Rise is the change in y and Run is the change in x. From the two given points, starting at (-3,-1) and going to (3,3):  

Rise = (2 - (-1)) = +3

Run = (3-(-3)) = 6

Slope is Rise/Run, or 3/6 = 1/2

 The equation becomes y = (1/2)x + b We can find b by entering a point and solving for b. I'll use (-1,0):

y = (1/2)x + b

0 = (1/2)(-1) + b

b = 1/2

The equatuion is y = (1/2)x + 1/2
