Answer:

y = 8.9

Step-by-step explanation:

8^2 + y^2 = 12^2

64 + y^2 = 144

subtract 64 from both sides

y^2 = 80

square root both sides

y = square root 80

y = 8.9

Write the equation of the linear function for which f(0)=3 and f^-1(0)=-2
Semmy [17]
We know that if f(a)=b then f^{-1}(b)=a
and
if f^{-1}(a)=b then f(b)=a
so


since f^{-1}(0)=-2 therefor, f(-2)=0

we have 2 points, (-2,0) and (0,3)

we can use slope intercept form
y=mx+b
m=slope
b=y intercept

we have when x=0, y=3, that is the y intercept
y=mx+3

substitute the other point
(-2,0)
x=-2, y=0
0=-2m+3
-3=-2m
divide both sides by -2
\frac{3}{2}=m


the equation is
y=\frac{3}{2}x+3
or
3x-2y=-6 in standard form

aniked [119]

Answer:

Suppose that in the inventory problem, the storage cost depends on the maximum inventory size, rather than the average. This would be more realistic if, for example, the company had to build a warehouse large enough to hold the maxi- mum inventory, and the cost of storage was the same no matter how full or empty the warehouse was. Show that in this case the number of units that should be ordered or manufactured to minimize the total cost is q= âfM/k

I need help on this!!
olga nikolaevna [1]

Answer:

Commutative

Step-by-step explanation:

Given

3 + b + 2 = 3 + 2 + b

Required

What law is applied

The applied law is commutative law of addition.

This law states that:

a + b = b + a

So:

3 + b + 2 = 3 + (b + 2)

When the positions of 2 and b are interchanged, we have:

3 + b + 2 = 3 + (2 + b)

Remove bracket

3 + b + 2 = 3 + 2 + b
