What is the answer for -8i-7i?
Numbers of the form a + ib (where i = -11/2; a and b are real numbers) are called complex numbers.
For any two complex numbers (a+ib) and (c+id):
Addition:
(a+ib) + (c+id) = (a+c) + i(b+d)
So, -8i-7i = (-8-7)i = -15i
A sine wave is the graph of y = sin(x). It demonstrates to cyclic nature of the sine function.

Why Is their always an integer between two integers?
There is no reason to give, because that's not a true statement.
Examples:
There is no integer between 4 and 5, or between 27 and 28, or between 792 and 793.
Why a 5 poloynominals wont fit in a 4 by 4 square?
Polynomials have infinite ranges and so none of them will fit in any square - no matter ow large the square is.
What is the importance of trigonometry in your daily life?
Trigonometry is important in daily life for many reasons. People use patterns and symmetry in relating to objects around them. For example. trigonometry is used in decorating a home.
yes most of the star sines are very accurate and the can determine what may or may not happen in latter or present life. some things may not go to you liking but you will get past them latter in life with time
Base = 12 inches
Area = (b x h)/2
24 = (b x 4)/2
48 = b x 4
12 = b
How can you determine the expire date of products?
While there is date on many products this is seldom a expiry date (the implication is that after the days the food or medication has gone bad) There is however a date to signify a "use before date" or "sell before date" to ensure freshness and customer satisfaction.
The bearing to that person or object is the heading it traveled on. Draw a right triangle by drawing an x-y coordinate plane to match East (x) and North (y) with the origin matching the point of departure. Now draw a perpendicular line from the new position to the x-axis and the hypotenuse to represent the distance traveled (r). The heading is actually the angle from north to the hypotenuse, so the angle at the origin INSIDE the triangle is its complement (angle A).
Use the sin and cos to find the x (east distance) and the y (north distance)
Sin A = y/r so, y = r (sin A) similarly x = r (cos A)
What is the height of the tree to the nearest tenth of a foot?
There is insufficient information in the question to answer it. Please restate the question.
In maths what does to find a product mean?
To find a product means when you multiply numbers together, the answer is your product.
For example, the product of 6 and 3 is 18, because 6 x 3 = 18.
What are the applications of integration in real life?
The integration of application is used in real life when applied to the psychology of group dynamics and the effects of bullying to weaker members of a group.
How are a triangular prism and triangular pyramid volume formulas alike and different?
The answer will depend on what aspect the formula is for: the surface area or the volume being the most obvious options.
How is trigonometry use in the field of navigation?
Spherical trigonometry is used to locate places on the earth's surface. All maps are based on trigonometry.
Global Positioning Systems (GPS) depends on three or more satellites picking up radio signals from your device. Trigonometry is then used to triangulate your position - that is, determine where you are in relation to each of the satellites. This gives your current location, from which you can navigate to your destination.
What is sin cos tan csc sec cot of 135 degrees?
All those can be calculated quickly with your calculator. Just be sure it is in "degrees" mode (not in radians). Also, use the following identities:
csc(x) = 1 / sin(x)
sec(x) = 1 / cos(x)
cot(x) = 1 / tan(x) or the equivalent cos(x) / sin(x)
