Answer:
The fabric needed for each pyramid cell of the kite will have an area of 173 cm².
Step-by-step explanation:
Area of a face of the triangular pyramids = (1/2)(b)(h)
where
b = base of a triangle of the triangular pyramid = 20 cm
h = height of each triangle of the triangular pyramids = 17.3 cm
Area = (1/2)(20)(17.3) = 173 cm²
Just like the image presented with the question, each face of the pyramid that has a cell of fabric has only one, So, the fabric needed for each pyramid cell of the kite will have an area of 173 cm².

The gradient is 3/4
Now we need to work out the gradient of the 2nd line. Remember that when 2 lines are perpendicular the product of their gradients is -1. Let's call the gradient of the second line m.
<span><span>3/4m = -1</span><span>m = -4/3</span></span>
In the question we are told that the line passes through the point (0, 2). This means that the line crosses the y axis at +2.
So the equation of the line that is perpendicular to 4y - 3x = 8 is y = - 4/3x + 2
Finding the gradient of a line between two points
To find the gradient of a line we need to know how many it goes up, for every one across.
Example
Find the gradient of the line joining (1,3) to (4,9).
As we go from (1,3) to (4,9) the y value increases by 6, and the x value increases by 3. So the line goes 6 up for 3 across. So this line has a gradient of 6/3 = 2.
Use this technique to answer the following question:
<span>QuestionLine A goes through the points (4, 9) and (1, 3). Find the perpendicular line through the point (2, 0).</span>
Answer:
C, HL
Step-by-step explanation:
Since the triangles share a side, they have a congruent leg. Looking at the tick marks, the triangles also have congruent hypotenuses. So, they are congruent by the Hypotenuse Leg theorem.
N^(7-3) = n^4
When dividing indices, you subtract the indices. If we multiply, you add them.
