Any more help feel free to ask
sinx-✓(1-3sin2x)=0
-✓(1-3sin2x)=-sinx
apply squared both sides
(-✓(1-3sin2x)^2=(-sinx)^2
1-3sin2x=sin2x
collect like terms
-3sin2x-sin2x+1=0
-4sin2x+1=0
-4sin2x=-1
devide both sides by -4
sin2x=-1/-4
sin2x=0.25
sinx*sinx =0.25
[sinx]^2 = 0.25
apply square root both sides
<h2>✓(sinx)2 = ✓0.25</h2>
<h2>sinx=0.5</h2><h2> </h2><h2>x=sin^-(0.5)</h2>
<h2>x=30°</h2>
<h3>check quadrant where sin is positive, sin is +ve in second quandrant</h3>
180-x= Theta(X)
180-30=X
X=150°
therefore, all angles for sinx -✓(1-3sin2x)=0 are (X= 30° and 150°)
The generic equation of the line is:
y-yo = m (x-xo)
Where, the slope is:
m = (y2-y1) / (x2-x1)
m = (1-4) / (2 - (- 1))
m = (1-4) / (2 - (- 1))
m = (- 3) / (3)
m = -1
We choose an ordered pair:
(xo, yo) = (- 1, 4)
Substituting values:
y-4 = -1 (x + 1)
Rewriting:
y = - x - 1 +4
y = -x + 3
Answer:
The equation of the line, in slope-intercept form, that contains the points (-1, 4) And (2,1) is:
y = -x + 3
Answer:
Percentage = 6.8% or 7%
Explanation
cold = 25/100
Large = 27/100
large multiplied by cold = (25/100 x 27/100) / 25 x 27 = 0.0675 x 100
= 6.75%
Percentage = 7 %
or 6.8 % to 1dp
The length would be w+4 since it is 4 inches more than the width, which is w.
