Answer:
Will’s Wrapping Company needs 7,720 mm2 of paper to wrap the chocolate bar.
Step-by-step explanation:
we know that
The amount of paper needed to make the wrapper is equal to the surface area of the chocolate bar
The surface area of a rectangular prism (chocolate bar) is equal to
where
B is the area of the base
P is the perimeter of the base
H is the height of he prism
In this problem we have
<em>Find the area of the base</em>
<em>Find the perimeter of the base</em>
<em>Find the surface area</em>
Answer:
7m+3
Step-by-step explanation:
distribute the - to 7m+1
14m+4-7m-1
now add like terms
7m +3
Answer:
f(y) = y(y - 4).
Step-by-step explanation:
The function has two x-intercepts of the function are (0,0) and (4,0).
X-intercept means that the y-value will be zero.
Therefore, the function f(y) has two roots, one at y = 0 and another at y = 4.
Hence, the function x = f(y) has two factors (y - 0) and (y - 4)
So, the function is f(y) = (y - 0)(y - 4) = y(y - 4). (Answer)
Inverse variation is of the form y=k/x (direct variation is of the form y=kx)
We are given that x=2 when y=1 so using the inverse form y=k/x we can solve for the constant of variation...
1=k/2
k=2
so the equation is:
y=2/x now they want us to find y when x=-1 so
y=2/-1
y=-2
