Solving Exponential Equations (lacking a common base) 31^d=38

Mathematics
1 answer:
Bond [772]3 years ago
8 0

Answer:

d = log 38/log31

d = 1.06

Step-by-step explanation:

31 ^ d = 38

Take log of both sides since the exponential equation have different base (always)

d log 31 = log 38

d = log 38 / log 31

d = 1.58 / 1.491

d = 1.06.

We can actually check to see if this is correct.

Substituting d = 1.06

31^ 1.06 = 38.092

(You see, that's approximately correct)

Keep learning, maths is fun!

The ratio of the number of beads Karen had to the number of beads Patricia had was 2:5 .After Patricia bought another 75 beads,t
blondinia [14]
K:P=2:5
P+75 it is 4:15
at first, P=5 units
so we have
2:5 and 4:15
since the K units didn't change we conver them to the same
2:5 times 2:2=4:10
so from 4:10 to 4:15 is a change of 75 in the right side
therefor 75=5 units so 75/5=15/1= 1 unit
so at first K=4 units=4 times 1 unit=4 times 15=60
P=10 units so 10 times 15=150

at first
Karen=60
Patricia=150

Identify tan P as a fraction and as a decimal rounded to the nearest hundredth. HELP PLEASE!!
KonstantinChe [14]
<h3>Answer: Choice C</h3>

================================================

Work Shown:

Reference angle = P

Opposite side = QR = 8.5

Adjacent side = QP = 16

tan(angle) = opposite/adjacent

tan(P) = QR/QP

tan(P) = 8.5/16

tan(P) = 0.53125

tan(P) = 0.53

Michael has a bus rental agency. He has 18 buses available, of which 8 have air conditioning (A.C.). What is the probability tha
Inessa05 [86]

Answer:

4 / 9

Step-by-step explanation:

Solution:-

- Michael bus rental agency has a total of n = 18 buses.

- Out all the available buses he has r = 8 buses with AC in them.

- If we were to randomly select a bus from his agency what is the probability that the bus would have an AC:

           P ( Bus with AC ) = Favorable Outcomes / Total outcomes

                                        = Number of bus with AC / Total Buses

                                        = r / n

                                        = 8 / 18

                                        = 4 / 9
