Answer:
Answer - -5
Step-by-step explanation:
Hello,
y=sin²(cos(2x))
y'=2*sin(cos(2x))*cos(cos(2x))*(-sin(2x)*2)
= -4*sin(cos(2x))*cos(cos(2x))*sin(2x)
Answer:
The towel costs 110 rupees
Step-by-step explanation:
Let n be napkins, and t be towels. Then:
6n+t=200
and
n=t-95
So:
6(t-95)+t=200
7t-570=200
7t=770
t=110....................
The slope of the given line is -4/5. The line perpendicular to that line will have a slope that is the opposite reciprocal. In other words, the perpendicular slope will be 5/4. If it passes through (4, 12), we have an x and a y value to use in y=mx+b. y is 12, x is 4, and we have a slope of 5/4. Filling in accordingly:
and 12 = 5 + b. So b = 7. Rewriting with our new slope and b value,
. And there you go!
Answer:
7=x
Step-by-step explanation:
multiply 5 and 2x by 2, you'll then have (10+4x)=-4+6x. Then add 4 to both sides and you have (14+4x)=6x. Subtract 4x from both sides and that'll get you 14=2x and you divide 2 from each side to get x by itself so 7 is your answer.
