Hey there! :)

You have to find the area of all of them and add it together.

Formulas:

Area of a square: l · w
Area of a triangle: (b · h) ÷ 2

Square - 

l = 2
w = 2

2 × 2 = 4

Triangle - 

b = 2
h = 4

(4 · 2) ÷ 2
   8   ÷   2 = 4

There are 4 triangles

4 × 4 = 16

16 + 4 = 20

The surface area ⇒ 20 cm²

SA of a pyramid: 1/2ph + B
p = perimeter of base
h = slant height
B = area of base

Perimeter of base:
The pyramid has a square base, so take a side of the base and multiply it by 4 sides to find the perimeter of the base.
(2)(4) = 8 cm

Slant height: 
The diagram shows that the slant height of the pyramid is 4 cm.

Area of base:
Since the pyramid has a square base, square one side of the base to find the area of the pyramid.
2cm² = 4 cm²

Now plug in the perimeter, slant height, and area of the base into the formula for SA of a pyramid.

1/2(8)(4) + 4 
16 + 4 = 20 cm²

The surface area of the pyramid is 20 cm².

Given the function g(x) = 4(3)x, Section A is from x = 1 to x = 2 and Section B is from x = 3 to x = 4.
LenaWriter [7]
Easy peasy


the average rate of change in section A is the slope from (1,g(1)) to (2,g(2))
the average rate of chagne in section B is the slope from (3,g(3)) to (4,g(4))



A.

section A
g(1)=4(3)^1=12
g(2)=4(3)^2=4(9)=36
slope=(36-12)/(2-1)=24/1=24

section B
g(3)=4(3)^3=4(27)=108
g(4)=4(3)^4=4(81)=324
slope=(324-108)/(4-3)=216/1=216



section A has an average rate of change of 24
section B has an average rate of change of 216

Find the value of x and the value of y.
kodGreya [7K]

Answer:

6√3 = x           y =12

Step-by-step explanation:

Since the two sides of the triangles have equal angles then two sides have equal length

the sum of interior angles of triangles is 180° then the last angle is 60°

then the triangles have perfect sides of 12

y = 12

to calculate x

sin Ф = opposite/hypothenus

sin 60° = x/12

sin 60° = √3/2

( √3/2 )  x 12  = x

6√3 = x
