Answer:
The surface area of the pyramid is 208 units²
Step-by-step explanation:
Luckily, since this is a square pyramid, we only need to find two numbers. These two numbers are the area of the base and the area of one triangular side. After we find them, we need to add them all together.
First, the base:
Since it's a square, we can just do 8 · 8 and get 64. Now we have one of the two needed numbers.
Second, one of the triangles:
To start, we multiply the base (8) by the height (9) giving us 72. After we divide that by 2, we have the area of the triangle, which is 36. Now we have the second number down. Now we can...
Finally, add them all together:
Now that we have the area of the base (64) and one of our triangles (36), we need to add them together. We add the base once and the triangle four times (because there are four triangles) to get the total surface area. Our expression looks like this:
64 + 36 + 36 + 36 + 36
After doing some simplifying, we get our final number, 208.
The surface area of the pyramid is 208 units²

Answer:
You can identify the parent function by making the equation into its simplest form.
Step-by-step explanation:
Remove all transformations from the equation (such as plus/minus signs, constants, and extra terms in the equation).
ex. y= -3x^2+15
The parent function would be y=x^2 after removing everything.
Hope this helps! :)
The definition of density is given by:
D = m / V
Where,
m: mass
V: volume
The volume of the rectangular prism is given by:
V = (0.3) * (2.1) * (0.1)
V = 0.063 mi ^ 3
Substituting the values:
D = 0.07 / 0.063
D = 1.111111111 Kg / mi ^ 3
Round to the nearest tenth:
D = 1.1 Kg / mi ^ 3
Answer:
the density of the board is:
D = 1.1 Kg / mi ^ 3
Answer:
Nominal interest rate is = 9% converible quaterly
we need to find monthy effective interest rate
0.09
i = 0.00744 or 0.75% approximately
i can also be taken as = 0.09/12
now PV of annuity will be the market price i.e x
6 60 *2 ---------------------a
Multiply equation by \frac{1}{1+i} both sides
6 60 2 PV ---------------b
Subtract equation b from a
60 2 PV (1 1+i (1+2)1 (1+2)2 (1+2)3 (1+2)60 (1+961
60 2 PV( 1 +i
on putting i = 0.00744
PV = 2733.88 approximately
X = 2733.88
