s place.
11. 7^(x-3)=25

12. log (3x+1)

13. log(7x+1) = log(x-2) +1

14. 4e^(2x)-3=12

Lim (1 + 1/x)^(3x) as x->infinity
kobusy [5.1K]
Lim ln([(x+1)/x]^3x) as x ->.infinity =lim ln([(x+1)^(3x)]/[x^(3x)]) as s->infinity =lim ln((x+1)^(3x))-ln(x^(3x)) = infinity - infinity
your answer is e3 but you can use l'hopital if you liketake the log, get 3xln(1+1/x)which is in the form ∞×0 then use the usual trick of rewriting as ln(1+1/x)/1/3x

What is the answer plz show your work<br> 7-4(d-3)=23
NNADVOKAT [17]
7-4 (d-3)=23
7-4d+12=23 **multiply -4 with (d-3)***
7+12-4d=23
19-4d=23
-4d=23-19
-4d=4
d=4÷-4

Find tan2θ if θ terminates in Quadrant IV and cosθ =3/5 .
Liula [17]

Answer:

The answer to your question is  \frac{-8}{3}

Step-by-step explanation:

Data

cos Ф = 3/5

tan2Ф = ?

Quadrant IV

Process

1.- Remember that tanФ = \frac{Opposite side}{Adjacent side}  and cos Ф = \frac{adjacent side}{hypotenuse}

then,    adjacent side = 3 and hypotenuse = 5

2.- Calculate opposite side

             O² = h² - a²

             O² = 5² - 3²

             O² = 25 - 9

              O² = 16

              O = 4

3.- Calculate the tan 2Ф

            tan 2Ф = 2(\frac{-4}{3})       The opposite side is negative in the fourth

                                           quadrangle

            tan 2Ф = \frac{-8}{3}
