Answer:
a)The number of aces in the poker hand is greater
b)It is about
as accurate.
Answer:
The format of the equation of a line is y=mx+c so in order to know whether which line is perpendicular to line y=5x-9, gradient of y=5x-9,which is 5,has to multiply by another gradient to get -1.[in short m1×m2=-1]
So the equation perpendicular to line y=5x-9 has a gradient of -1÷5=-1/5
Answer:
D. 1.06(3.19x + 1.20y + 1.20z)
Step-by-step explanation:
Since marker packs are 3.19 each, the cost of the marker packs she buys can be represented by 3.19x.
All spiral notebooks are 1.20 each, so the cost of the wide ruled notebooks can be represented by 1.20y.
The cost of the college ruled notebooks can be represented by 1.20z.
In the expression, all of these terms have to be added together and multiplied by 1.06 to calculate the sales tax.
So, the expression will be 1.06(3.19x + 1.20y + 1.20z)
D is the correct answer
Sure I will give two examples
Application of tangents
1. If we are traveling in a car around a corner and we drive over something slippery on the round ( like water , ice or oil ) , our car starts to skid
It continue in a direction tangent to the curve
Application of tangents
2. Have you ever sat on a merry- go around
If yes , then you would understand
From your experience when I tell you that the force your experience is towards the centre of merry- go around but your velocity ( the tendency of motion) is in the way toward which your body pointing
Another way saying the same thing would be to let you know that your velocity at any point is tangent while force .
At any point is normal to the circle along which you are moving
Can you draw connection between both the ways of saying the same thing?
Have this two example help you
Good luck :D
