Answer:
Blue fabric (triangles) = 27 m²
Green fabric (square) = 9 m²
Step-by-step explanation:
✔️Blue fabric (triangles) = 4(area of triangular face)
= 4(½*b*h)
b = 3 m
h = 4.5 m
= 4(½*3*4.5)
= 27 m²
✔️Green fabric (square) = area of the square base
= s²
s = 3
Area = 3²
= 9 m²
Answer:
- time = 1second
- maximum height = 16m
Step-by-step explanation:
Given the height of a pumpkin t seconds after it is launched from a catapult modelled by the equation
f(t)=-16t²+32t... (1)
The pumpkin reaches its maximum height when the velocity is zero.
Velocity = {d(f(x)}/dt = -32t+32
Since v = 0m/s (at maximum height)
-32t+32 = 0
-32t = -32
t = -32/-32
t = 1sec
The pumpkin reaches its maximum height after 1second.
Maximum height of the pumpkin is gotten by substituting t = 1sec into equation (1)
f(1) = -16(1)²+32(1)
f(1) = -16+32
f(1) = 16m
The maximum height of the pumpkin is 16m
Answer:
The estimated area is 
Step-by-step explanation:
we know that
To estimate the area that Ivan will paint , calculate the area of one wall and then multiply by 3
step 1
Convert the dimensions to an improper fractions
step 2
Find the area of one wall
step 3
Multiply the area of one wall by 3
step 4
Convert to mixed number
There are no like terms in 9u^2v because it is all one term and none of the variables are like one another.
