Answer: A. x + (4x - 85) = 90

In this case, the two angles are complementary. This means they add up to 90°. Therefore, the equation is x + (4x - 85) = 90.

Graph the function<br> Need help ASAP plz
sattari [20]

Given:

The equation of a function is

y=(x-4)^2+1

To find:

The graph of the given function.

Solution:

The vertex form of a parabola is

y=(x-h)^2+k        ...(i)

Where, (h,k) is vertex of the parabola.

We have,

y=(x-4)^2+1         ...(ii)

From (i) and (ii), we get

h=4, k=1

The vertex of the parabola is (4,1).

Now, the table of values is

x             y

2            5

3            2

4             1

5            2

6            5

Plot these points on a coordinate plane and connect them by a free hand curve.

The graph of given function is shown below.

What are the real or imaginary solutions of the polynomial equation x*4-25=0​
Paul [167]

Hello from MrBillDoesMath!

Answer:

Solutions: x = +\- 5i or x = +\- sqrt(5)


Discussion:

Factor x^4 - 25:

x^4 - 25     = (x^2+5) (x^2-5)                              =>  factor x^2 - 5

x^4 - 25 =   (x^2+5)(x + sqrt(5)) (x - sqrt(5))       => factor x^2 + 5

x^4 = 25  = (x +5i)(x-5i) (x + sqrt(5)) (x - sqrt(5))  

Hence the solutions are

x = +\- 5i and x = +\- sqrt(5)



Thank you,


MrB
