Answer:Plug the numbers into the exponential growth formula:

Now work backwards to get the answer:

1)Divide 120150 by 60100 to get 1.998668885

2) Find the 11th root of ANS:

3) Minus 1 from your answer to give 0.064976629

4)Multiply your answer by 100 to give you the rate of x%, which is 6.5 to 1d.p

x=6.5 (1 d.p.)

Btw, this answer also works if you plug it back into the equati

Which is the graph of f(x) = Square root of x?

natka813 [3]

Answer:

Third option given

Step-by-step explanation:

On a coordinate plane, a parabola opens to the right with a vertex at (0, 0).

use the following x values to plot the associated y values on the x-y plane:

If x = 0, then $y=\sqrt{0} =0$

If x = 1, then $y=\sqrt{1} =1$

If x = 4, then $y=\sqrt{4} =2$

If x = 9, then $y=\sqrt{9} =3$

Join the points and you will find a branch of a parabola opening to the right.

Solve equation, check for extraneous solutions

Start with

$1=\dfrac{1}{n^2}+\dfrac{n^2-4n-5}{3n^2}$

We observe that both fractions are not defined if $n=0$ . So, we will assume $n \neq 0$ .

We multiply both numerator and denominator of the first fraction by 3 and we sum the two fractions:

$1=\dfrac{3}{3n^2}+\dfrac{n^2-4n-5}{3n^2} = \dfrac{n^2-4n-2}{3n^2}$

We multiply both sides by $3n^2$ :

$n^2-4n-2=3n^2$

We move everything to one side and solve the quadratic equation:

$2n^2+4n+2=0 \iff 2(n^2+2n+1)=0 \iff 2(n+1)^2=0 \iff n+1=0 \iff n=-1$

We check the solution:

$1=\dfrac{1}{1}+\dfrac{1+4-5}{3} \iff 1 = 1+0$

which is true

Idk how to do this honestly

Anuta_ua [19.1K]

I get the answer being the same y= -1/2x +

Because b in intercept form is "0"

I used
m=y2-y1/x2-x1
M=-3-2/6-4
M=-5/10
M=-1/2

(-4,2)
Y=mx+b
2=-1/2 (-4)+b
B=2-(-1/2)(-4)
B=0

I did the same for second point
And got "0" for b

So my answer is get
Y=-1/2x

Unless someone else gets something else different.

I hope somewhat helps
