hope it helps :) give brainlist
Answer:
<u>-4</u>
Step-by-step explanation:
Average rate of change (Table 1) :
- A(x) = h(4) - h(1) / 4 - 1
- A(x) = 9 - 3 / 4 - 1
- A(x) = 6/3 = 2
Average rate of change (Table 2) :
- A(x) = j(4) - j(1) / 4 - 1
- A(x) = 0 - 6 / 4 - 1
- A(x) = -6/3 = -2
Difference : -2 - 2 = <u>-4</u>
Answer:
B: 2 and 3
Step-by-step explanation:
Area of rectangle = Length*width
A = 28 so 28 = 4 * height
height = 28/4 = 7
Round pan volume is:
3.14•r^2•h
D=7 so r=3.5 in
3.14• (3.5^2)•2 = 76.97 in^3
Rec. pan vol. is :
9•6•2= 108 in^3
Rec. Pan is larger because 108 in^3 is > 76.97 in^3 :) .
The icing that will be needed to frost the round cake pan is:
We need to find the surface area:
S.A= 3.14r^2 + 2 • 3.14•r • h .... 3.14 is the value of PI
So, S.A= 3.14• 3.5^2 + 6.28• 3.5• 2= 82.47 in^2 the icing that'll be needed to frost the round cake pan.
Icing that will be needed for the rec. cake pan is:
2•9•2=36 in^2
6•9•2= 108in^2
6•2= 12 in^2
S.A= 156 in^2 the icing needed to frost the rec. cake pan .... the S.A of all sides except the bottom one :).
Good luck ;-)
