Answer:
- c0 = 8
- c1 = 24
- c2 = 30
- c3 = 42
Step-by-step explanation:
It is convenient to notice that the pattern of coefficients that need to be multiplied and summed is a pattern of Xs.
For the constant, c0, only the constants need to be multiplied.
c0 = 4·2 = 8
__
For the x-term coefficient, the constant of one series needs to be multiplied by the x-term of the other, and the two products added.
c1 = 4·5 +2·2
c1 = 24
If you draw real or imagined lines between the coefficients being multiplied, you see that they form an X.
__
For the x²-term coefficient, the above X gets wider, and a vertical | is added. That is constant multiplies x² term and x-term multiplies x-term. The sum has three terms:
c2 = 4·3 +2·4 +2·5
c2 = 30
__
For the x³ term, there are now two Xs, one wide and one narrower. Constant terms multiply x³ terms and x-terms multiply x² terms.
c3 = 4·3 +2·2 +2·3 +5·4
c3 = 42
_____
This sort of pattern of Xs can be used wherever polynomials (or multidigit numbers) are multiplied. It can help you ensure that all of the products that need to be included in a sum are accounted for.
Answer:
x = 2.4
Step-by-step explanation:
For this equation, you need to use trigonometry. we only need to use one of the two angles given and for this example i'm going to use the 60° angle. as we know the adjacent side and want to know the opposite side, we need to use the trig ratio tan
in this case, we will replace the adjacent side with
the square root of 2.
= 
as the side we know is on the bottom of the ratio, we need to multiply it by the ratio (tan) then the angle (in case you don't know, * means multiply)
round to 1 decimal place
x = 2.4
Hope this was helpful :-)
I'm sorry if this was confusing, trigonometry is very hard to explain.
There are two measures 5 cm then the triangle will be isosceles or 16 is far beyond 5 + 5 = 10 so we cannot build any triangle so te answer is <span>B none
