Answer:
8sin(x)cos³(x)
Step-by-step explanation:
sin(4x) +2 sin(2x) = 2sin(2x)*cos(2x) + 2sin(2x) = 2sin(2x)(cos2x + 1)=
= 2sin(2x)(cos²x - sin²x + cos²x + sin²x)=²2sin(2x)*(2cos²x)=
= 4*2sin(x)*cos(x)*cos²(x)= 8sin(x)cos³(x)
Answer:
y = 90°
Step-by-step explanation:
The left side base angle of the triangle and the angle of 110° form a straight angle and are supplementary, thus
base angle = 180° - 110° = 70°
The right base angle is also 70° , thus the triangle is isosceles
The line segment from the vertex is a perpendicular bisector, hence
y = 90°
Answer:
6.25 minutes
Step-by-step explanation:
First, let's simplify it down. We want to find out how many shirts she can fold in 1 minute, then multiply that by 50.
20 shirts in 2.5 minutes
20 shirts = 2.5 minutes
An equals sign is like a see-saw. If you do something to one side, you have to do it to the other side. To get 20 shirts to 1 one shirt, divide by 20. You have to do that to the other side to make it equal.
(20 divided by 20) = (2.5 divided by 20)
1 shirt = 0.125 minutes.
That's how long it takes to fold 1 shirt. To find the time for 50 shirts, multiply that by 50.
0.125 x 50 = 6.25
It will take Carrie 6.25 minutes to fold 50 shirts. Hope this helped =)
