What is the lateral area of the pyramid?
Aleks04 [339]

We have two triangles with base 9ft and height 12.3ft and two triangles with base 11ft and height 11.9ft.

The formula of an area of a triangle:

A_\triangle=\dfrac{1}{2}bh

Triangle #1:

b = 9ft and h = 12.3ft. Substitute:

A_1=\dfrac{1}{2}(9)(12.3)=55.35ft^2

Triangle #2:

b = 11ft and h = 11.9ft. Substitute:

A_2=\dfrac{1}{2}(11)(11.9)=65.45ft^2

The Lateral Area:

L.A.=2A_1+2_A2\\\\L.A.=2(55.35)+2(65.45)=241.6\ ft^2

<h3>Answer: B. 241.6 ft².</h3>

(co<br> Write a cosine function that has an amplitude of 2, a midline of 5 and a period of 8.
tatyana61 [14]

Answer:

<em>y=2 cos (π/4x-π/4)</em>

Step-by-step explanation:

<em>Given</em>

<em>A cosine function has an amplitude of 2, a midline of 5 and a period of 8.</em>

<em>To find: </em>

<em>A cosine function.</em>

<em>Explanation:</em>

<em>Let the function be,</em>

<em></em>y=Acos(ws+p)

<em>Since amplitude is 2.</em>

<em>Then,</em>

<em></em>A=2

<em>Also, since the period is 8.</em>

<em>Then,</em>

<em></em>w=\frac{2\pi }{8}

w=\frac{\pi }{4}

<em>And, since midline is 5.</em>

<em>Hence, the cosine function is,</em>

<em>y=2 cos (</em>\frac{\pi }{4}<em>x-</em>\frac{\pi }{4}

<em></em>
