Answers
After a devastating winter, when thousands of fish died, an environmental scientist has replenished the trout stock in a fishing pond. He started with 5,000 baby trout and has finished a count to find that, in 4 years, the population is estimated to be 8,500. Assuming an exponential growth pattern, what is the annual growth rate (rounded to the nearest tenth of a percent) of the new trout population?
Answers
The annual growth rate of the new trout population is approximately 12.0%.
Explanation:To find the annual growth rate of the trout population, we can use the exponential growth formula:
P = P0ert
where P is the final population, P0 is the initial population, r is the annual growth rate, and t is the number of years.
In this case, we have P = 8,500, P0 = 5,000, and t = 4. Plugging these values into the formula, we can solve for r:
8,500 = 5,000e4r
Divide both sides by 5,000:
1.7 = e4r
Take the natural logarithm of both sides:
ln(1.7) = 4r
Divide both sides by 4:
r ≈ ln(1.7)/4 ≈ 0.120
Final answer:
The annual growth rate of the trout population is calculated using the formula for exponential growth. By substituting the given values into the formula, the growth rate is determined to be approximately 13.41% per year. After rounding, the annual growth rate is 13.4%.
Explanation:
To calculate the annual growth rate of the trout population, we can use the formula for exponential growth, which is P = P0e(rt), where:
P is the final population size,
P0 is the initial population size,
r is the annual growth rate,
t is the time in years.
We know that P0 = 5,000 (initial population), P = 8,500 (final population), and t = 4 years. To find r, we rearrange the formula to solve for r:
r = (ln(P/P0)) / t
Plugging in the values gives us:
r = (ln(8500/5000)) / 4 = ln(1.7) / 4 ≈ 0.1341 or 13.41% per year
Rounding to the nearest tenth of a percent, the annual growth rate is 13.4%.

There are 7 numbers between 1 and 100 that are multiples of both 2 and 7.
Explanation:To find the numbers between 1 and 100 that are multiples of both 2 and 7, we need to find the common multiples of these two numbers. The multiples of 2 are 2, 4, 6, 8, 10, and so on. The multiples of 7 are 7, 14, 21, 28, and so on.
We can see that the common multiples of 2 and 7 are 14, 28, 42, 56, 70, 84, and 98. There are a total of 7 numbers between 1 and 100 that are multiples of both 2 and 7.

The demand for a new electric guitar causes a music store to increase the price of the guitar by 45%. If the guitar originally costs $320, what is the new price of the guitar?
Answers
The new price of the guitar is $464.
Hope this helps!
Answer:
The new price of the guitar would be $464.00
Step-by-step explanation:
The original price of the guitar = $320
The music store increased the price of guitar by = 45%
First we calculate 45% of the 320 and then add it to the original price.
The new price of the guitar = 320 + ( 45% × 320 )
= 320 + ( 0.45 × 320 )
= 320 + 144
= $464
The new price of the guitar would be $464.00

write general rule for adding
a. two integers with the same sign.
b. two integers with different signs.
c. two integers that vary in sign.
Answers
b. Subtract, and give the difference the sign of the number with the greatest absolute value.
When adding integers, if the signs are the same, add the numbers and keep the sign. If the signs are different, subtract the smaller number from the larger number, using the sign of the larger number.
Explanation:To offer some general rules for adding integers, consider the following scenarios:
When we add two integers with the same sign, we add the absolute values of the numbers and keep the common sign. For example, (-4) + (-3) equates to -7, as they are both negative. If we are combining two integers with different signs, we subtract the smaller number from the larger number and use the sign of the larger number. For instance, 7 + (-2) equals 5, because 7 is larger and positive. When adding two integers that vary in sign, it suggests that one number could be positive and the other negative or vice-versa. Thus, we follow the second rule mentioned above. For example, -6 + 3 gives -3 because 6 is bigger and negative. Learn more about Adding Integers here:

For which value or values are the expressions 15k + 9 and 3(2k + 3) + 9k equivalent? A) no values B) 3 C) 3,5 and 8 or D) all values
Answers
15k + 9 = 6k + 9 + 9k
15k + 9 = 15k + 9
0 = 0
D) all Values
Final answer:
The expressions 15k + 9 and 3(2k + 3) + 9k are equivalent for all values of k because after simplifying the second expression, it matches the first expression exactly.
Explanation:
To determine for which value or values the expressions 15k + 9 and 3(2k + 3) + 9k are equivalent, we must first simplify the second expression.
Simplify 3(2k + 3) + 9k:
= 6k + 9 + 9k
= 15k + 9.
Now we compare the simplified forms of both expressions. It is clear that they are identical in form, meaning that they are equivalent for all values of k. No additional values are needed; the expressions are universally equivalent as they simplify to the same equation.

Find the values of x and y that make k || j and
m || n.
Answers
IF (x - 30) + (x + 50) = 180 then, line line n || m.
x - 30 + x + 50 = 180
2x + 20 = 180
subtract 20 from both sides
2x = 160
divide both sides by 2
x = 80
IF (x - 30) + y = 180, then k || j.
(80 - 30) + y = 180
50 + y = 180
subtract 50 from both sides
y = 130
The values of x and y are 80 and 70 respectively which make k parallel to j and m parallel to n.
Geometrically, parallel means two or more lines, line segments, or rays that never intersect or cross each other, it doesn't matter how far they are extended. Parallel lines always maintain the same distance between them and remain equidistant at every point.
The sum of two adjacent angles is [tex]180^o[/tex],
therefore,
[tex](x-30)^o+(x+50)^o= 180^o[/tex]
2x +20 = 180
2x = 180 - 20
2x = 160
[tex]\frac{2x}{2} = \frac{160}{2}[/tex]
x = 80.
Again, as the sum of two adjacent angles is [tex]180^o[/tex],
[tex](x-30)^o+y^o= 180^o[/tex]
x + y = 180 + 30
Substitute value of x,
80 + y = 150
y = 150 - 80
y = 70.
Thus, x = 80 and y = 70 are the values for which k is parallel to j and m is parallel to n.
