Solve 5x-3is less than 3x plus 1 when x is an integer?
5x-3 < 3x+1 5x-3x < 1+3 2x < 4 Divide both sides of the inequality by 2 to find the value of x: x < 2 So x is an integer whose value is less than 2 such as 1, 0, -1, -2, -3, .........
Trigonometry is engineering math, but If you are going to study something in physics, or science, (basically this is "applied science"), you will need lots of calculus.
calculus appears a lot in "Stargate".
What is the value of moment of inertia of ellipse about its centroidal axis?
If an ellipse has a radius A long the x-axis and B along the y-axis (A > B) then the moment of inertia about the x-axis is 0.25*pi*ab^3

Why misd architecture has never been used?
MISD didn't exist when Flynn was categorizing the machines. It might have been added for symmetry in his chart. Its applications are very limited and expensive and currently there seems to be no commercial implementation. But it is a research interest topic. One example is systolic array with matrix multiplication like computation. With rows of data processing units (cells) sharing the information with their neighbors immediately after processing.
in second and fourth... for angles 135 and 315 degrees
What is the importance of trigonometry in seafaring?
For navigational purposes and knowing how to work out 3 figure bearings from North in a clockwise direction
Which is the formula for days of supply calculation?
Days of Supply = Total Inventory / Average daily consumption (forecasted for example).
Can be calculated as a gross value using inventory values or for an individual part using volume.
Why do plants need fertilizer?
As we need water and food to do our daily tasks similarly plants also need different chemicals to complete their life cycle. Nitrogen, potassium and phosphorus are the most important chemicals. These chemicals are absorbed by the plants through the soil or water. As we know, a lot of crops are being harvested in only one patch of land. So gradually the amount of essential plant nutrients in the soil decreases and soil can't provide the desired quantity of essential plant nutrients to the plants and consequently, the growth of plants is effected. So these plant nutrients are provided to the soil in the form of fertilizer. Actually, fertilizer contain necessary amount of essential chemicals according to the need of soil. In short fertilizer are used for the better growth of plants.
Where does the word etymology come from?
From greek "etymon" - true sense, + "logos" - word
in effect, "the true sense of words"
How many degrees are in the angles of a trapezoid?
They can vary in size. In its most general form, a trapezoid (or trapezium, outside of North America) is a four-sided figure with exactly one pair of parallel sides. The two parallel sides do not have to be the same length; therefore a trapezoid will have either:
- Two acute angles (less than 90º) and two obtuse angles (greater than 90º) OR
- Two right angles, one acute angle, and one obtuse angle.
Case (2) is a special type of Case (1).
Regardless of its configuration, the interior angles of a trapezoid always add up to 360 degrees
Can you draw an equilateral triangle using a straightedge and compass?
Yes, it is quite simple.
Draw a straight line segment, AB. Put the compass point at A and open it so that the pencil point is at B. Then draw an arc. Next, without changing the compass setting move it to B and draw another arc to cut the previous arc at C. [Actually there will be two points, one on either side of AB.] Using the straight edge, join AC and BC. Then ABC is an equilateral triangle.
What are the basic trigonometry functions?
The 3 most common trigonometry functions are as follows:
- Sine (opposite/ hypotenuse)
- Cosine (adjacent/hypotenuse)
- Tangent (opposite/adjacent)
An easier way to remember these is SOH-CAH-TOA which, when pronounced out-loud, sounds kind of like "soak a toe".
WHAT instrument is used to find angle of elevation?
A protractor is commonly used on two-dimensional renderings.
What are some examples of how circles are used in architecture?
notre dame in paris - the arches are based on intersecting circles
How do you graph seven vertices with two bridges?
Assuming that each bridge can connect at most two vertices, you will need at least 4 bridges to connect seven vertices. Conversely, two bridges will connect at most four vertices.
If 1 is a radian measure, using a calculator, sin(1)=0.84147
How do you find the angle of an triangle?
you know a triangle always measure 180 degrees
the two angles you are given add them together
then subtract 180-_____the blank is for the sum of the two addends
How do you get a period of 3 in a cosine function?
The argument of the cosine function must be (2pi/3)*x radians
How do you simplify trigonometric identities?
Work out what relationships you have, and how they can be converted to others. Then use those relationships and substitute them for other simpler ones. Often these will allow you to simplify a furtehr step. Keep going until it can't get any simpler.
Beyond that, it takes practise to notice the patterns and straight-up memory to know what turns into what.
