Katarina [22]3 years ago
3 0

The equation to find the area of a trapezoid is, A=(base1+base2)xHeight/2

1) (5+23)x12/2= 168

2) (1.1+3.4)x2/2= 4.5

3)(17.75+10.25)x8/2= 112

Find the values of x and y
Mkey [24]

Answer:

x = 78º

y = 35º

Step-by-step explanation:

These are isosceles triangles

two angles are congruent

-----------------------------

x + 51 + 51 = 180

x = 180 - 102

x = 78º

y + y + 110 = 180

2y = 70

y = 35º

Find an equation for the plane y=4x in cylindrical coordinates. (Type theta for θ in your answer.)
Paha777 [63]

Answer:

<h2><em>sinθ - 4cosθ = 0</em></h2>

Step-by-step explanation:

Given the equation of a plane in rectangular coordinates to be y = 4x.

The cylindrical coordinates of the axis is as given below;

x = rcosθ

y = rsinθ

z = z

Since there is no z coordinate in the equation of the plane given, we will only substitute x = rcosθ and y = rsinθ into the equation y = 4x and simply the result as shown;

y = 4x

rsinθ = 4( rcosθ)

rsinθ = 4rcosθ

sinθ = 4cosθ

sinθ - 4cosθ = 0

<em>Hence the equation for the plane in cylindrical coordinate is expressed as sinθ - 4cosθ = 0</em>

A cube-shaped item needs to be painted. The item’s edge length is 2 centimeters. What is the total surface area that will be pai
marysya [2.9K]
For this case, what we must do is find the surface area of the cube.
 By definition, the surface area of a cube is given by:
 A = 6L ^ 2&#10;
 Where,
 L: length of the sides of the cube.
 Substituting values we have:
 A = 6 (2) ^ 2&#10;&#10;A = 6 (4)&#10;&#10;A = 24 cm ^ 2
 Answer:
 
The total surface area that will be painted is:
 
24 cm²
