Answer:

x+2=\pm2

Step-by-step explanation:

He started with (x+2)^2-9=-5.

He add 9 to both sides and the resulting equation was

(x+2)^2=4

Next, he took the square root of each side.

The resulting equation of this step is:

(x+2)=\pm \sqrt{4}

x+2=\pm2

The required equation is:

x+2=\pm2

Answer:

21.8 m/s

Step-by-step explanation:

Given that Tom drops a object from a height of <em>h </em>meters and it hits the ground with a veloc8of <em>v </em><em>m/</em><em>s </em>and it is given by function ;

\longrightarrow v =\sqrt{19.6h}

We need to find out the velocity upon reaching the ground when it is dropped from a height of 24.3 m . On plugging in 24.3 in place of h we have ,

\longrightarrow v =\sqrt{19.6\times 24.3 }\ m/s\\\\\longrightarrow v =\sqrt{ 476.28} m/s \\\\\longrightarrow v = 21.823 \ m/s \\\\\longrightarrow \underline{\underline{ v = 21.8 \ m/s }}

And we are done !

Answer:

21.1%

Step-by-step explanation:

(25 - 24.3) / 1.2 = 0.5833 z score = 78.9%

You need the percent that spend more than 25 hrs per week, so 100 - 78.9 = 21.1%

A website uses the formula above to calculate a seller’s rating, R, based on the number of favorable reviews, F, and unfavorable
slava [35]
The correct formula is

RN/(1-R) = F.

To solve for F, we start by multiplying by (N+F) to remove it from the denominator:
R(N+F) = F

Distributing, we have:
RN + RF = F

Subtracting RF to collect all of the F's on one side,
RN = F - RF

Factoring out F on the right hand side,
RN = F(1 - R)

Dividing both sides by (1-R), 
RN/(1-R) = F
