Answer:
yes yes no no
Step-by-step explanation:
is that what u want
I know the equation is 1/cos
but is it negative sqrt(3)/2 or positive?
or is it negative 1/2 or positive?
This makes the reference angle π/6 or 30º which gives cos 30º=√3/2 or a sec value of 2/√3=2√3/3
sec(-5pi/6)=-2√3/3
Because they're consecutive, it means that the first one is x, the second one is x+1, the third one is x+2 (x+1+1), and the fourth one is x+3. Because we're given that the sum of all of them is 682, just add all of them together:
x+(x+1)+(x+2)+(x+3)=682
x+x+x+x+1+2+3=682
4x+6=682
4x+6-6=682-6
4x=676
x=676/4
x=169
Thus, the consecutive integers are: 169, 170, 171, 172
So add
1/5+3/8
convert bottom number to same number
5 times 8=40
bottom mub be 40
1/5 times 8/8=8/40
3/8 times 5/5=15/40
add
1/5+3/8=8/40+15/40=(8+15)/40=23/40
so completed 23/40 total
