Answer: D

Step-by-step explanation:

The answer is (i) and (ii). In the first graph, as x approaches very large values such as infinity, the y-value will also approach infinity. In the second graph, as x approaches infinity, the y-value again approaches infinity.

On the contrary, the third graph approaches large negative values as x increases. It approaches negative infinity.

What is the lateral surface area of the square pyramid below?

Studentka2010 [4]

Answer:

$=4(\dfrac{1}{2}\times Base \times Height )\\\\=4(\dfrac{1}{2} \times 3 \times 8 )\\\\=4(\dfrac{1}{2} \times 24 )\\\\=4 \times 12\\\\=48\,\,inch^2$

Therefore, Lateral surface area of the pyramid= $48\,\,inch^2$

Step-by-step explanation:

The lateral surface area of the pyramid is the area of the all of its four triangular faces, excluding base :

Area of a triangle is:

$=\dfrac{1}{2} \times Base \times Height\\$

Base= 3 inches

Height=8 inches

Lateral surface area of the pyramid:

$=4(\dfrac{1}{2}\times Base \times Height )\\\\=4(\dfrac{1}{2} \times 3 \times 8 )\\\\=4(\dfrac{1}{2} \times 24 )\\\\=4 \times 12\\\\=48\,\,inch^2$

Therefore, Lateral surface area of the pyramid= $48\,\,inch^2$

<h3>Answer: Choice A. </h3><h3>interior = 140, exterior = 40</h3>

===================================================

Explanation:

For me, I find it easier to find the exterior angle first. For any convex polygon, the sum of the exterior angles is 360 degrees. When we talk about regular polygons with n sides, each exterior angle is 360/n degrees. In this case, we have a nonagon with 9 sides. So n = 9 is plugged into 360/n to get 360/9 = 40 as the exterior angle measure

exterior angle = 40

We could stop here since we can see the answer must be choice A. But let's keep going. To get the interior angle, we subtract the result we got from 180

interior angle = 180-(exterior angle) = 180-40 = 140

This is because any adjacent pair of interior and exterior angles must form a straight angle of 180 degrees.

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

side note: you could use the formula $i = \frac{180(n-2)}{n}$ to find the measure of the interior angle.
