Answer:
Rounded to the nearest tenth: 
in
Rounded to the nearest hundredth: 
in
Step-by-step explanation:
We have a right triangle with a given angle of 35°. We also have the opposite side of that angle, 
, and its hypotenuse 10 in. To find , we are using the trig function that relates the opposite side with the hypotenuse; in other words, the sine trig function.
Rounded to the nearest tenth: in
Rounded to the nearest hundredth: in
Y=4x-3=1
Y=-2x+9=11 that’s the answer
The option that's true about the plane illustrated is E. None of these.
<h3>How to illustrate the plane?</h3>
From the information given, it should be noted that DBC isn't an isosceles triangle.
Also, from the figure, one can see that DAB isn't similar to DAC.
Likewise, BD and DC aren't perpendicular.
In conclusion, the correct option is E.

Answer:
length = 200 m
width = 400 m
Step-by-step explanation:
Let the length of the plaing area is L and the width of the playing area is W.
Length of fencing around three sides = 2 L + W = 800
W = 800 - 2L ..... (1)
Let A is the area of playing area
A = L x W
A = L (800 - 2L)
A = 800 L - 2L²
Differentiate with respect to L.
dA/dL = 800 - 4 L
It is equal to zero for maxima and minima
800 - 4 L = 0
L = 200 m
W = 800 - 2 x 200 = 400 m
So, the area is maximum if the length is 200 m and the width is 400 m.
4=2c-12-4
4=2c-16
20=2c
10=c
