PLEASE HELP ASAAP 25 PTS + BRAINLIEST TO RIGHT/BEST ANSWER
Nutka1998 [239]

Let i = sqrt(-1) which is the conventional notation to set up an imaginary number

The idea is to break up the radicand, aka stuff under the square root, to simplify

sqrt(-8) = sqrt(-1*4*2)

sqrt(-8) = sqrt(-1)*sqrt(4)*sqrt(2)

sqrt(-8) = i*2*sqrt(2)

sqrt(-8) = 2i*sqrt(2)

<h3>Answer is choice A</h3>

Corresponding angles are congruent (same measure)

Corresponding sides are all in the same proportion

That means AB/ BC = CE/ED

Harco<br> Find the inverse function f-¹(x) for the given function f(x).<br> 5. f(x) = 4x-8
ipn [44]

The inverse function for the given function f(x) = 4x - 2 is x/4 + 2

or, f⁻¹(x) = x/4 + 2

Given function, f(x) = 4x-8

We have to find f⁻¹(x)

f(x) = 4x - 8

or, y = 4x - 8

Interchanging the x variable with y,

x = 4y - 8

Solving y,

x = 4(y - 2)

or, x/4 = y - 2

or, y = x/4 + 2

Now, replacing y with  f⁻¹(x), we get;

f⁻¹(x) = x/4 + 2

For verifying, you can use

(f · f⁻¹ )(x) = x

Therefore, the inverse function of f(x) is x/4 + 2.

Please help with question 6.
otez555 [7]
Being directly proportional means that both variables are increasing at the same rate, so both variables will be doubling. in that case:

a. y = x(^2)

if x is doubled

(2y) = (2x)^2

y is increasing by a factor of 2

b. y = x(^3)

if x is doubled

(2y) = (2x)^3

y again, increases by a factor of 2
