To which set(s) of numbers does the number sqrt -16 belong? Select all that apply.

Mice21 [21]

<span>The square root of -16 is an imaginary number and a complex number. Sqrt(-16)=4i. We use the i to indicate that the number is imaginary since there is no number that can be multiplied by itself to get a negative number (a negative times a negative is a positive, and a positive times a positive is also a positive). So the use of i tells you immediately that it's an imaginary number. You can tell the number is complex because it has both a real and an imaginary part and could be written in the form a+bi, where a is a real number and bi is an imaginary number. In this specific case, the real part (a) is 0 and the imaginary part (bi) is 4i.</span>

What is the solution to the equation? <br><br> √2x+10 -6=2

klio [65]

$\sqrt{2x+10} -6=2
$
$\sqrt{2x+10} =8$ we switched side of -6 and added it to 2
2x + 10 = 64 now we squared both sides to get rid of square root
2x = 54 we switched side of +10 and subtracted it from 64
x = 27 we divided both sides with 2

answer is x = 27

What is the rate of change of the function shown on the graph? Round to the nearest tenth.

faltersainse [42]

<u>Answer</u>:

The required is the multiplicative rate of change.

The correct answer is the second option<u> 2.5</u>

<u>Step-by-step explanation:</u>

The given function has the form of the exponential function

The general equation of the exponential function $y=c * r^x$

Wher c is constant and r is the multiplicative rate of change.

Using the given points to get the values of c and r

By using the point (0,2) ⇒∴ $2=c * r^0$ ⇒ c = 2

By using the point (1,5) ⇒∴ $5=2 * r^1$ ⇒ r = 5/2 = 2.5

Check the answer using the other points

If x = 2 ⇒⇒⇒ $y=2 * 2.5^2 = 12.5$

If x = -1 ⇒⇒⇒ y=2 * 2.5^(-1) = 0.8

<u>So, the multiplicative rate of change = 2.5</u>
