Formula for pyramid:

$V=b^2\frac{h}3$

Where,

b = base - 3.5 m

h = height - 5 m

Thus,

$V=3.5^2\frac{5}{3}$

$20.41667m^3$ ≈ $20.42m^3$

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

Formula for pyramid:

$V=b^2\frac{h}3$

Where,

b = base - 3 m

h = height - 4.3 m

Thus,

$V = 3^2\frac{4.3}{3}$

$12.9m^3$

lara [203]

The linear equation represents y = mx + b describes several real world situations such as

Relation between printer and ink cartridges,

Relationship between number of songs and how much is left on the card.

Step-by-step explanation:

Linear equations y = mx + b.

m is your rate of change.

b is your constant. This is the initial value of y. The value of y when x is 0.

Finally, y is the thing that depends on x.

Oh right, examples:

I buy a printer for $100 and the ink cartridges cost $25 each. The relationship between ink cartridges and total cost.

total cost = 25(cartridges I buy) + 100 or y = 25x + 100

I get a $100 iTunes gift card for my birthday and then start buying $1 songs. The relationship between the number of songs I buy and how much is left on the card

amount left on card = -$1(songs bought) + 100 or y = -x +100
