No because if it did it would not be a function at all
So the question wants you to add all the coins together then subtract 15% SO
16+28+32+4=80
so 15% of 10=10%+5%
5%=1/2 of 10% so
10% of 80=8
5% of 80=10%/2=8/2=4
8+4=12
he sold 12 coins
Answer:
Length and Width = 10ft
Height = 5ft
Surface Area = 300 square feet
Step-by-step explanation:
Given
-- Volume
Let:
Volume (V) is calculated as:
Substitute 500 for V
Make H the subject
The tank has no top. So, the surface area (S) is:
Substitute 500/LW for H
Differentiate with respect to L and to W
and
Equate both to get the critical value
and
and
and
and
Make L the subject in
Substitute for L in
Cross Multiply
Divide both sides by 1000
Take cube roots of both sides
Substitute 10 for W in
Recall that:
So, the dimensions are:
and
The surface area is:
Answer:
n = -6
Step-by-step explanation:
4 + = 2
= -2
n = -6
Answer:
I'm not sure if you have the question quite right. Whenever you multiply x and y by something, it is a dilation. So 3 of those are dilations. If you add or subtract something from x, it is a translation.
Hope that helps.
