2

Answer 1

A painting is purchased for $350. If the value of the painting doubles every 5 years, then its value is given by the function V(t) = 350 • 2t/5, where t is the number of years since it was purchased and V(t) is its value (in dollars) at that time. What is the value of the painting ten years after its purchase?
1,400
What is the solution to the equation 21x + 3 = 14
x ≈ –2.133

Answer 2

What is the solution to the equation 7^ 3x ≈ 9
x = 0.376

Answer 3

are those all right so far ?

Answer 4

hold on a bit

Answer 5

first q, you mean Answer is 11.7 years ?

Answer 6

yesss .

Answer 7

first q = \(\color{red}{\checkmark}\)

Answer 8

(; . okkk good

Answer 9

second q = \(\color{red}{\checkmark}\)

Answer 10

(:

Answer 11

for 3rd q, 1400 = \(\color{red}{\checkmark}\)

Answer 12

(:

Answer 13

for 4th q, x ≈ –2.133 = \(\color{red}{\checkmark}\)

Answer 14

okkk . (: are you ready for the nesxt few ?

Answer 15

5th q also \(\color{red}{\checkmark}\)

Answer 16

yea you seem to be always right lol

Answer 17

hahaha (:.
Which of the following is equivalent to log 40 8 rounded to three decimal places?
0.564
What is the solution of log 2x + 3125 = 3 ?
x = 4
Which of the following is equivalent to log 2x 3y ?
log(3y)/log(2x)
Which of the following is the simplified version of 3 log x + log y + log z ?
logx^3y/z

Answer 18

0.564 is correct

Answer 19

but next question is wrong

Answer 20

):. awee ok . lets see what i did wrong

Answer 21

What is the solution of \(\log_{ 2x + 3}125 = 3\) ?

Answer 22

is it really 2x+3, or 2x-3 ?

Answer 23

2x+3,

Answer 24

cuz i remember, we did the 2x-3 in subscript before

Answer 25

just check once

Answer 26

yup but thay changed the subscript

Answer 27

ohk... lol then answer changes too

Answer 28

lets solve it real quick

Answer 29

okkk (:

Answer 30

\(\log_{ 2x + 3}125 = 3 \)

\(125 = (2x+3)^3\)

\(5^3 = (2x+3)^3\)

\(5 = 2x + 3\)


solve x

Answer 31

2=2x
x=1
okk. i see what i did wrong i mad it 8=2x on accident

Answer 32

ok good, next

Answer 33

next q is \(\color{red}{\checkmark}\)

Answer 34

last q is wrong. they changed the q again it seems

Answer 35

Which of the following is the simplified version of \(3 \log x + \log y + \log z\) ?

Answer 36

you sure, all + signs u have there ?

Answer 37

oh sorry no i had put logx^3/yz. but we can be sure and check it .

Answer 38

\(3 \log x + \log y + \log z\)

all + signs ? can u look at q and confirm

Answer 39

yess thats right.

Answer 40

then u simply multiply

Answer 41

\(3 \log x + \log y + \log z\)

\(\log x^3 + \log y + \log z\)

\(\log x^3 y z\)

Answer 42

so ii was right ?

Answer 43

cuz \(\log a + \log b = \log ab\)

Answer 44

Which of the following is the simplified version of 3 log x + log y + log z ?
logx^3y/z

Answer 45

you have placed z in the bottom, so you're not right

Answer 46

ohhhhhhhhhhhhh! okkkk . sorry lol i got it now.

Answer 47

ok last few.

x = 0.5
What is the solution to the equation 1√8=4^(m + 3) ?
-11/4

222

Answer 48

its okay :)

Answer 49

(:

Answer 50

first q, \(\color{red}{\checkmark}\)

Answer 51

second q, wrong

Answer 52

ok im going to redo it.

Answer 53

let me check 3rd q, before coming back to second q

Answer 54

ok you try, meantime il check 3rd q ok

Answer 55

ok

Answer 56

for last q, 222 = \(\color{red}{\checkmark}\)

Answer 57

ok the last one is
Which of the following is equivalent to log 4 32 ?
2.5

Answer 58

thats right, wat about the wrong q

Answer 59

ok i redid the second one and got -15/4. im not sure its right though.

Answer 60

-15/4 = \(\color{red}{\checkmark}\)

Answer 61

Excellent work !

Answer 62

yayyy thank you veryyy muchhh (:

Answer 63

ou got more

Answer 64

yes i do . im going to run an arron then tagg you in any more . btw i got a 100% (:
