Y=x² – 8x + 16

so right now i'm trying to figure out the inverse relation

The inverse relation is:

Step-by-step explanation:

We need to solve for x.

Useful formula: (x-y)^2=x^2-2xy+y^2.

Now, take the square root of both sides:

Add 4 on both sides:

Interchange x and y:

The inverse relation is:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
