Tgα = tan(α) = sqrt(2)/1 = opposite/ adjacent
opposite = sqrt(2)
adjacent = 1
hypotenuse = sqrt(opposite^2 + adjacent^2)
= sqrt(sqrt(2)^2 + 1^2) = sqrt(3)
sin(α) = opposite/hypotenuse
= sqrt(2)/sqrt(3)
cos(α) = adjacent/hypotenuse
= 1/sqrt(3)
now we can calculate the value of
5sin²α+3cos²α / 3sin²α-5cos²α
... do the math
So you want to find the price for 1 apple you find that by dividing so 23.60/5=4.72
and 32.76/7=<span>4.68
so, the 7 bag for 32.76 is the better deal</span>
So, in order, you have to multiply first. 3x3=9, now you have to do 2+2=4. Since there is a "plus" in between "2+2" and "3x3" you have to add, 9+4=13.
(56*a*b)/b= 56a
Remember that multiplying by b and then diving by b cancels out, leaving only 56a left
Final answer: 56a
4 + (3x) = y (or total amount)
start with 0, then work your way up:
(0, 4)
(1, 7)
(2, 10)
(3, 13)
(4, 16)
etc
hope this helps
& may Joan of Arc bring you good tidings XD
