Answer:
9 hours and 30 mins
Step-by-step explanation:
This is the right answer
Sin2x=2sinxcosx, cos2x=1-2sin^2x
sin(2x)+cos(3x)=2sinxcosx+cos(x+2x)
cos(x+2x)=cosx(1-2sin^2(x))-sinx2sinxcosx
sin(2x)+cos(3x)=2sinxcosx(1-sinx)+cosx(1-2sin^2(x))
Answer:
1:4, 2:8 and 6:24
Step-by-step explanation:
Okay so you didn't give me the list of ratios so in this question I'm assuming we can make our own equivalent ratios.
First things first we could simply simplify the ratio.
3:12
3/3=1
12/3=4
1:4
Since they're asking for three I'm going to now just multiply so we can create the equivalent ratio.
1:4
1x2=2
4x2=8
2:8
1:4
1x6=6
4x6=24
6:24
These ratios are random but equivalent to 3:12 since you didn't give me the list.
(Hopefully this helped)
Answer:
the diagonal is about 6.4 units
Step-by-step explanation:
i used pythagorean theorem to solve for the diagonal
a^2 + b^2 = c^2
5^2+ 4^2 = c^2
25+16=c^2
41= c^2
square root of 41 = c
6.4=c
c is the diagonal length
