Answer:

1075 square feet.

Step-by-step explanation:

multiply 25 by 35 to get the big rectangle area, that's 875.

next the smaller rectangle area, 8 times 25. that's 200.

add em together and boom, 1075.

Find sin(x/2), cos(x/2), and tan(x/2) from the given information.
Nimfa-mama [501]

The values of sin (x/2) = 4/√17,   cos (x/2) = 1/√17 and  tan (x/2) = 4.

<h3>What is Trigonometry?</h3>

Trigonometric ratios are the ratios of the length of sides of a triangle. These ratios in trigonometry relate the ratio of sides of a right triangle to the respective angle.

Here, cos x = -15/17  (given)

we know, cos x = 2cos²x/2 - 1

                cos²(x/2) = (cos x + 1)/2

                  cos²(x/2) = (-15/17 + 1)/2

                 cos²(x/2) = 1/17

                 cos (x/2) = 1/√17

then, sin (x/2) = √(1- cos²(x/2))  

          sin (x/2) = √(1 - 1/17)

          sin (x/2) = √16/17

          sin (x/2) = 4/√17

and tan (x/2) = sin (x/2) / cos (x/2)  

       tan (x/2) = \frac{4/\sqrt{17} }{1/\sqrt{17} }

       tan (x/2) = 4

Thus, the values of sin (x/2) = 4/√17,   cos (x/2) = 1/√17 and  tan (x/2) = 4.

What is an equation of the line that passes through the points (6,−4) and (−6,2)? Put your answer in fully reduced form
katovenus [111]
Y=mx+b
m=slope
b=yintercept
slope=(y1-y2)/(x1-x2)
(x,y)
x1=6
y1=-4
x2=-6
y2=2

(-4-2)/(6-(-6))=-6/12=-1/2
y=-1/2x+b
subsitute one point
(6,-4)
x=6
y=-4
-4=1/2(6)+b
-4=3+b
subtract 3
-7=b
y=-1/2x-7 is answer

I need help pleaseee asap
Tasya [4]

Step-by-step explanation:

there is no big "trick" involved.

you just need to do the multiplication and then move the terms into the right spot, so that the x-, y- and constant terms are in the same place as the generic Ax + By = C

y + 5 = 4(x + 1)

y + 5 = 4x + 4

-4x + y = -1

or (after multiplying both sides by -1)

4x - y = 1

yes, B = 1 (or -1), so you could write 1y (or -1y) instead of only y (or -y).

but nobody does that.
