$5.25 / 150 gets you the price per vitamin, $.035 (3.5 cents). Then you can multiply this by 250 for the price of a 250 bottle, $8.75.

What is the explicit formula for this sequence?<br><br> −7, −4, −1, 2, 5, …
VikaD [51]

The explicit formula for the sequence is 3n -10

<h3>What is an Arithmetic Sequence ?</h3>

An arithmetic sequence is a series of terms which have  common difference between its consecutive numbers.

The sequence given is

−7, −4, −1, 2, 5, …

The common difference between each term is d =3

-4-(-7) = 3

-1-(-4) =3

The nth term for a sequence is given by

\rm T_n =  a +(n-1)d

Here a is the first term = -7

n is the no. of terms  = n

d is the common difference = 3

Therefore the equation will be

\rm T _n = -7 + (n-1) * 3

\rm T _n = -7 +3n -3

\rm T _n = 3n -10

Therefore the explicit formula for the sequence is 3n -10 .

Which equation has the same soultions as x^2+6×-7=0
blagie [28]
x^2+6x-7=0 \\   a=1 \\ b= 6 \\ c=-7 \\ \\  \boxed{\boxed{\Delta=b^2-4ac}} \\ \\ \Delta=6^2-4*1*(-7) \\ \Delta=36-(-28) \\ \Delta=64 \\ \Delta\ \textgreater \ 0 \Rightarrow \text{we have 2 solutions :} X_1 \ and X_2 \\ \\ \boxed{X_1= \frac{-b- \sqrt{\Delta} }{2a} } \Rightarrow X_1= \frac{-6-8}{2}=-7 \\ \\ \boxed{X_2= \frac{-b+ \sqrt{\Delta} }{2a} } \Rightarrow X_2= \frac{-6+8}{2} =1
