lnx=-3
the answer in the textbook says it becomes x=e^-3 which I agree with, but then it gives 0.05 as the answer to solving it, I just don't understand how they found 0.05. Can anyone explain how to get 0.05 from x=e^-3?
Answer:
because It's rounded to the nearest hundred place
Step-by-step explanation:
Given equation:
[tex] \ln(x ) = - 3[/tex]recall that,
[tex] \ln(a ) = b \iff {e}^{b} = a[/tex]
remember, In is natural logarithm which is actually nothing but common logarithm with the base euler's number (e) . anyway rewriting lnx=-3 yields:
[tex] \ln( x ) = - 3\\ \iff {e}^{ - 3} = \frac{1}{ {e}^{3} } [/tex]
1/e³ is approximately 0.0497870684..... , rounding it to the nearest hundred place would be 0.05 which is the same answer as your textbook .

Of the 1250 students registered at the local high school, 30% of them did not vote during the student body elections. How many students did not vote?
A) 350
B) 425
C) 365
D) 375
Answer: D) 375
Step-by-step explanation:
We will find 30% of 1,250 since 30% did not vote. A percent divided by 100 becomes a decimal.
30% / 100 = 0.3
1,250 * 0.3 = 375
D) 375 students did not vote.

The function f(x)=log2x is transformed 4 units down and vertically compressed by a factor of 0.2 to become g(x).
Which function represents the transformation g(x)?
The answer is: g(x)=15log2(x)−4
Using translation concepts, it is found that function g(x) is given by:
[tex]g(x) = \frac{1}{5}\log_{2}{x} - 4[/tex]
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, the parent function is given by:
[tex]f(x) = \log_{2}{x}[/tex]
It was shifted 4 units down, hence:
[tex]g(x) = \log_{2}{x} - 4[/tex]
It was vertically compressed by a factor of 0.2, hence:
[tex]g(x) = \frac{1}{5}\log_{2}{x} - 4[/tex]

Which expression can be subtracted from the area of the rectangle to find the area of parallelogram rstu? 2 (18 4) one-half (18 4) (18 4) (18 - 4)
The expression can be subtracted from the area of the rectangle to give the area of the parallelogram RSTU (18+4).
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
The coordinates of parallelogram RSTU are
R(-4, -3), S(-5, 1), T(4, 3), U(5, -1)
The lengths of the sides are
RS = 4.1231
RT = 10
ST = 9.2195
SU = 10.198
TU = 4.1231
UR = 9.2195
Therefore, by definition of a parallelogram, we have;
RS║TU and ST║UR
The slope of RS = (1 - (-3))/(-5 - (-4)) = -4
The slope of ST = (3 - 1)/(4 - (-5)) = 2/9
The equation of the line perpendicular to ST is
y - 1 = -9/2×(x - (-5))
y = -9x/2 - 43/2
The equation of RS = y - (-3) = 1/4×(x - (-4)) = x/4 + 1
y = x/4 - 2
The point where the two lines meet
-9x/2 - 43/2 = x/4 - 2
x = -78/19
y = -115/38
The length of the side of the rectangle = 4.1245
The excess width of the rectangle = 0.1085
The expression can be subtracted from the area of the rectangle to give the area of the parallelogram RSTU (18+4).

The probability of obtaining a head when a certain coin is flipped is about 0. 65. Which of the following is closest to the probability that heads would be obtained 15 or fewer times when this coin is flipped 25 times?.
The probability that heads would be obtained 15 or fewer times when this coin is flipped 25 times is 0.370
How to determine the probability?The given parameters are:
Sample size, n = 25Probability of success, p = 0.65Number of success, x ≤ 15The probability is represented using the following binomial formula
[tex]P(x) = ^nC_x * p^x * (1 - p)^{n - x}[/tex]

Which expression represents the value of the series below? 3 7 11 15 ... 1,671
Answer:
Let n be the sequence number, starting with 0. The first number is 3, each succeeding number is incremented by 4. The nth number would have the value 3+4n
Step-by-step explanation:
Using the above formula yields the attached table of values. We see that if n=417, that the value of 1,671 is correctly predicted.
If m and n are whole numbers such that m^n = 121, then find the value of (m-1)^n+1.
Because m and n are whole numbers, we only have 3 values for m, and 3 values for n :
[tex]1^{121} ; 11^{11} ;121^{1}[/tex] (or you can say because 121 only have the factors of 1 ; 11 ; 121, those are the only possible values for m and n, then conclude the possible values)
Now, we will substitute them in :
If m = 1 ; n = 121
[tex](1-1)^{121+1}[/tex] = 0
If m = 11 ; n = 11
[tex](11-1)^{11+1}[/tex] = 1000000000000
If m = 121 ; n = 1
[tex](121-1)^{1+1}[/tex] = 14400

Answer:
13: 16
14: 6.28
15: √45
Step-by-step explanation:
13: Count the number of spaces from A to D or B to C, which is 4.
Then, count the number of spaces from A to B or C to D, which is also 4.
After that, multiply the two numbers. You should now have an answer of 16.
14: You want to find the diameter of the circle, which is 2.
Then, multiply 2 by 3.14, aka pi. You should now have an answer of 6.28.
*15: Count the number of spaces from A to C, which is 6.
Then, count the number of spaces from A to B, which is 3.
After that, square both of the numbers. 6 x 6 = 36 and 3 x 3 = 9.
Now, the final step. Add both numbers together. 36 + 9 = 45.
You should now have an answer of √45.
