Step-by-step explanation:
what ? you cannot do even simplest subtractions ?
what is it you don't understand here ?
how such a function works ?
you take every value for x (the input variable or argument), put it in place of the "x" (this is nothing else than a placeholder for the actual values) and then perform the mathematical operations. y is then the result of that.
x = 0
y = 0 - 7 = -7
the ordered pair of (x, y) is (0, -7)
x = 1
y = 1 - 7 = -6
(1, -6)
x = -3
y = -3 - 7 = -10
(-3, -10)
x = -5
y = -5 - 7 = -12
(-5, -12)
Answer:
7(x+5)-(2xy^2)
that's how you would write the equation
Answer:
The maximum volume of cone is 138.25 m³
m
m
Step-by-step explanation:
A right circular cone whose hypotenuse is m
It is revolved about one leg to generate a right circular cone.
Let radius be r m and height be h m
For right angle triangle,
Volume of generated cone
Differentiate w.r.t h
For maximum/minimum
<em>Using double derivative test </em>
At
so get maximum volume.
Dimension of cone:
m
m
The maximum volume of cone is 138.25 m³
Answer:
d=8
Step-by-step explanation:
Okay we've got 68/17 and d/2
68/17 = 4 meaning d/2 is also 4. Since 4 × 2 is 8, we know the answer is 8.
