Answer:

The third term is 11.

The first negative term is the fifth term.

Step-by-step explanation:

If the nth term of the sequence is given by the expression 20-n^2, to find the third term, we just need to use the value of n = 3 in the expression:

20 - (3)^2 = 20 - 9 = 11.

To find which term is the first to have a negative value, we can solve the inequation 20 - n^2 < 0:

20 - n^2 < 0

n^2 > 20

n > 4.47

The first term to have a negative value is the fifth term:

20 - 5^2 = 20 - 25 = -5

Find the slope of the line (4,5),(-3,-1)
koban [17]

Step-by-step explanation:

{ \rm{slope =  \frac{y _{2} - y _{1} }{x _{2} - x _{1} } }} \\

• y2 → -1

• y1 → 5

• x1 → 4

• x2 → -3

{ \tt{slope =  \frac{ - 1 - 5}{ - 3 - 4} }} \\  \\ { \tt{slope =  \frac{ - 6}{ - 7} }} \\  \\ { \boxed{ \tt{ \: slope =  \frac{6}{7} }}}

Solve for L. m=LN+2/K
Iteru [2.4K]

Answer:

l = \frac{m  - \frac{2}{k} }{n}   \\  \\

Step-by-step explanation:

m = ln +  \frac{2}{k}  \\ m -  \frac{2}{k}  = ln \\  \frac{m -  \frac{2}{k} }{n}  =  \frac{ln}{n}  \\ l =  \frac{m  - \frac{2}{k} }{n}   \\

Sedaia [141]

Answer:

700

Step-by-step explanation:

Since t represents the amount of years after the opening and you want to know the amount of employees working there on opening day you can plug in 0 for t.

n=700(.2)^.5(0)

n=700
