Subract 67 from 60 = 7
60 - 53 = 7
add 7 to 67 & the then to the answer you get after that & the next 3 numbers are
1. 74
2.81
3.88
No it’s not a function because it doesn’t pass the vertical line test. if you do the test, you’ll find that the line intersects with the graph more than once
Answer:
Step-by-step explanation:
Represent the volume of the box with V and the dimensions with l, b and h.
The volume (V) is:
Make h the subject of the formula
The surface area (S) of the aquarium is:
Where lb represents the area of the base (i.e. slate):
The cost (C) of the surface area is:
Substitute for h in the above equation
Differentiate with respect to l and with respect to b
To solve for b and l, we equate both equations and set l to b (to minimize the cost)
By comparison:
becomes
Cross Multiply
Solve for l
Recall that:
Also recall that:
Apply law of indices
The dimension that minimizes the cost of material of the aquarium is:
Answer:
Step-by-step explanation:
Let's rewrite all the fraction to ratios
4:6, 10:12, 2:5, 4:7
Now, using the direct proportion, if one increase/decrease, the other increase/decrease by the same amount
4:6 = (4x2) : (6x)2 = 8:12
10:12 =( 10:2) : (12:2) = 5:6
2:5 = (2x3) : (5x3) = 6:15
4:7 = (4x2) : (7x2)= 8:14
Answer: six times a number, x
