Ln(x+5) + lnx=5 answer me fast

pashok25 [27]

Answer:

9.936

Step-by-step explanation:

In(x+5)*x=5

ln(x^2+5x)=5

e^5=x^2+5x

148.4131=x^2+5x

x^2+5x-148.4131=0

x is 9.936 because logs can't be negative

Pls see attached question

zimovet [89]

Answer:

Step-by-step explanation:

put it on a coorinate grid,

circle circumference = 2*pi*r = 100.53

so the arc 19.2/100.53 = about 0.15 times the circumference of the circle

0.15*2pi = angle AOB in radians = 0.97

length DE is like 7.44

angle DOE is approx 0.485 radians beacuse it's half of angle AOB

area of shaded region is 804.2477 probably. I'm not sure about this last one sorry I think my calculator messed up

Suppose you just purchased a digital music player and have put 15 tracks on it. After listening to them you decide that you like

blsea [12.9K]

Answer:

Total songs = 15

Liked songs = 3

Un liked songs = 15-3=12

Find the probability that among the first two songs played

(a) You like both of them.

Probability that among the first two songs played you like both of them = $\frac{3}{15} \times \frac{2}{14} = 0.029$

(b) You like neither of them.

Probability that among the first two songs played you like neither of them = $\frac{12}{15} \times \frac{11}{14} = 0.629$

(c) You like exactly one of them.

Probability that among the first two songs played you like exactly one of them = $\frac{3}{15} \times \frac{12}{14}+ \frac{12}{15} \times \frac{3}{14}= 0.343$

(d) Redo (a)-(c) if a song can be replayed before all

(a) You like both of them. Would this be unusual?

Probability that among the first two songs played you like both of them = $\frac{3}{15} \times \frac{3}{15} = 0.04$

(b) You like neither of them.

Probability that among the first two songs played you like neither of them = $\frac{12}{15} \times \frac{12}{15} = 0.64$

(c) You like exactly one of them.

Probability that among the first two songs played you like exactly one of them = $\frac{3}{15} \times \frac{12}{15}+ \frac{12}{15} \times \frac{3}{15}= 0.32$

Mary needs to send out some letters and postcards. She went online at the United States Postal Service webpage and found out tha

MissTica

Answer:6 postcards and 9 letters

Step-by-step explanation:

First we label what we are looking for

Label number of postcard sent as x

Label number of letter sent as y

The we know Mary wrote to 15people, either as postcard or letter, so from this we make an equation

x + y = 15 (1)

The we know the amount Mary used to send all this is $6.15 which is also 615 cents

Then we know sending one postcard is 35cents, and we labeled number of postcards to be x

So total amount used for postcard will be 35x

And we know sending one letter is 45 cents, and we labeled number of letters to be y

So total amount used for letter will be 45y, so adding all this will be equals to the total amount used which is given as $6.15 also 615 cents, so making another equation

35x + 45y = 615 (2)

Solving the two simultaneously equations

x + y = 15 (1)

35x + 45y = 615 (2)

So we make y the subject of formula in (1)

y = 15 - x (3)

So we put (3) in (2)

Anywhere we see y, we put 15-x

35x + 45(15-x) = 615

35x + 675 -45x = 615

35x - 45x = 615 - 675

-10x = -60

divide both sides by -10

x = 6

So therefore, number of postcards is 6

Then we put x = 6 in (3)

y = 15 - x

y = 15 - 6

y = 9

So therefore number of letters is 9
