Q9: Identify the graph of the equation and write an equation of the translated or rotated graph in general form. (Picture Provid
MArishka [77]

Answer:

D. Circle; (x²) + (y²)-4=0

Step-by-step explanation

Simplify the equation by dividing both sides by 2

2x² + 2y² =8

x² + y² =4

this gives a circle form where we can apply (x-h) ² +(y-k)² =r² to find center and radius of the circle.

Thus r=2, h=0, k=0

Center of circle is at (h, k), (0,0)

Radius of circle is 2

Which expression is equivalent to (x^6×x^10/×^-3)^2 and why?
mixer [17]

Answer:

The solution for the given expression is x^{38} , i.e option C

Step-by-step explanation:

Given expression as :

(\dfrac{x^{6}\times x^{10}}{x^{-3}})^{2}

Now, From the common radix method

<u>∵ In multiplication of radix , if the radix is same , then power is added</u>

I.e x^{6}\times x^{10 = x^{6+10}

Or , x^{6}\times x^{10 = x^{16}

Now, The expression can be written as

(\frac{x^{16}}{x^{-3}})^{2}

<u>And In Division of radix , if the radix is same , then power is subtracted</u>

So, \frac{x^{16}}{x^{-3}}

Or, x^{16 - (-)3}

Or,  x^{16 + 3}

or, x^{19}

∴ The expression is now

(x^{19})²

Now, again this is written as

x^{19} × x^{19}

I.e here again the radix is same and in multiple for, so, power is added

∴ x^{19} × x^{19}  = x^{19+19}

I.e x^{19} × x^{19} =  x^{38}

Hence The solution for the given expression is x^{38} , i.e option C  . Answer

emmainna [20.7K]

Answer:

f(-3)=g(-3)

Step-by-step explanation:

The graph shows two linear functions that intersect at (-3,-4).

The blue line is f(x).

At the point of intersection:

f(-3)=-4....eqn1

The blue line is g(x).

At the point of intersection

g(-3)=-4....eqn2

Equating both equations we get:

f(-3)=g(-3)

The statement that is true regarding the two functions is that:

f(-3)=g(-3)

How many and what type of solution(s) does the equation have?
zzz [600]

Answer:

2 irrational solutions.

Step-by-step explanation:

6p^2 = 8p + 3

0 = -6p^2 + 8p + 3

The roots are:

p = (2/3) - (8.5)^(1/2)/3, and

p = (2/3) + (8.5)^(1/2)/3

These are irrational numbers.

There are 2 irrational solutions.

Find the measure of an angle whose complement is five times its measure.
ch4aika [34]

Answer:

The measure of the unknown angle is 15°.

Step-by-step explanation:

Represent this angle by A.  Then the complement of A is 90° - A.

"Angle whose complement is five times its measure" would be expressed as

90° - A = 5A

Solve this for A by adding A to both sides:

90° = 6A.  Then A = 90°/6, or 15°
