Answer:

C = 79, B = 26 degrees

Step-by-step explanation:

tan C = 5.1323

To find C you  use your calculator . Press tan-1 ( or it might be arctan) then the value 5.1323 Then ENTER.

C =  79 degrees to nearest degree.

cos B = 0.8954

B = 26 degrees

Answer:

8 - 2π square units.

π/16 - 1/8 square units.

6π - 9√3 square units.

Step-by-step explanation:

The area of the square = 2√2 * 2√2

= 2*2*2

= 8.

The area of the circle = πr^2

= π * [ ( 2√2)/ 2) ]^2

=  π (√2)^2

=  2π.

Second Question:

The area of the circle = π(1/2)^2 = π/4.

Finding the area of the square:

1^2 = 2x^2

x^2 = 1/2

So the area of the square = 1/2

So the area of the red part = 1/4 ( π/4 - 1/2).

= π/16 - 1/8.

Third question

Area of the circle = 6^2 * π = 36π.

Now 60 degrees is 1/6 of 360 degrees so the are of the sector is 6π.

The area of the segment = 6π -  0.5 * 6^2 sin 60

= 6π - 18√3/2

= 6π - 9√3 square units.

What is the lateral surface area of the solid? Assume the top and bottom of
timama [110]

Check the picture below.

so the lateral area will be just the area of the sides, namely excluding the bases at top and bottom, thus

\stackrel{\textit{\LARGE Lateral Area}}{\stackrel{\textit{front and back}}{2(4)(5)}~~ + ~~\stackrel{\textit{left and right}}{2(4)(7)}}\implies 40~~ + ~~56\implies 96~cm^2

The point (1, –5) is reflected across the y-axis. A coordinate plane. What are its new coordinates?
luda_lava [24]
<h3>Answer:  Choice C.   (-1, -5)</h3>

Explanation:

The reflection rule we use is

(x,y) \to (-x, y)

when we want to reflect over the y axis. The x coordinate flips from positive to negative, or vice versa, while the y coordinate stays the same.

Therefore, (1, -5) \to (-1, -5)
