Answer:
Step-by-step explanation:
We do not add the triangles in because they are the bases and the bases do not get added in the lateral surface areas.
From left to right
Rectangle 1
A = lw = 9.9 *20 =198
Rectangle 2
A = lw = 6.8 *20 =136
Rectangle 3
A = lw = 9.9 *20 =198
Add them together
198+136+198
532
LSA = 532 yds ^2
First we move sin4x to right side
sin(2x) = sin(4x)
now we simplify 4x
<span>sin(2x) = sin(2*2x)
</span>using double angle formula
<span>sin(2x) = 2sin(2x)cos(2x)
</span>subtracting sin2x on both sides
<span>2sin(2x)cos(2x) - sin(2x) = 0
</span>taking sin2x common
<span>sin(2x) * (2cos(2x) - 1) = 0
</span>now using product rule
so
<span>sin(2x) = 0
or
2cos(2x) - 1 = 0
</span><span>cos(2x) = 1/2</span><span>
hence </span>
<span>x = 0 + nπ/2, π/6 + nπ, 5π/6 + nπ </span>
x = 0, π/6, π/2, 5π/6, π, 7π/6, 3π/2, 11π/6, 2π
Answer:
Ella should not have included 5 in absolute value portion of the equation
Step-by-step explanation:
Because -1 is a negative number in order to find the true distance between A and B you have to make it positive.
But, because Ella included 5 in the absolute value portion of the equation it messed up the answer.
1.176x10^8 is that answer you will go to the end of the 5 and count all the way up to between the 11 and then you will put the decimal between the 11 and keep putting the numbers till you get to a 0 then you times it by 10 to the 8th power and how you get the 8 is how many numbers you count over when you are putting the decimal between the 2 numbers on the end
Hi! I believe it’s D but not 100% sure- HOPE IT HELPS
