What is the multiplicative inverse of y?
9514 1404 393
Answer:
1/y
Step-by-step explanation:
The multiplicative inverse of an expression is its reciprocal. It is the value that, when multiplied by the original, give a product of 1 (the multiplicative identity element).
Here, that is ...
1/y
because (y)(1/y) = y/y = 1.

Zero (0) does not have a multiplicative inverse.
A major fishing company does its fishing in a local lake. The first year of the company's operations it managed to catch 115,000 fish. Due to population decreases, the number of fish the company was able to catch decreased by 6% each year. How many total fish did the company catch over the first 20 years, to the nearest whole number?
Answer:
Rounded to the nearest whole number, the company caught 1,360,630 fish in total over the 20 years.
Step-by-step explanation:
Given that a major fishing company does its fishing in a local lake, and the first year of the company's operations it managed to catch 115,000 fish but due to population decreases, the number of fish the company was able to catch decreased by 6% each year, to determine how many total fish did the company catch over the first 20 years, to the nearest whole number, the following calculation must be performed:
Year 1: 115,000
Year 2: 115,000 x 0.94 = 108,100
Year 3: 108,100 x 0.94 = 101,614
Year 4: 101,614 x 0.94 = 95,517.16
Year 5: 95,517.16 x 0.94 = 89,786.13
Year 6: 89,786.13 x 0.94 = 84,398.96
Year 7: 84,398.96 x 0.94 = 79,335.02
Year 8: 79,335.02 x 0.94 = 74,574.92
Year 9: 74,574.92 x 0.94 = 70,100.42
Year 10: 70,100.42 x 0.94 = 65,894.40
Year 11: 65,894.40 x 0.94 = 61,940.73
Year 12: 61,940.73 x 0.94 = 58,824.29
Year 13: 58,824.29 x 0.94 = 54,730.83
Year 14: 54,730.83 x 0.94 = 51,446.98
Year 15: 51,446.98 x 0.94 = 48,360.16
Year 16: 48,360.16 x 0.94 = 45,458.55
Year 17: 45,458.55 x 0.94 = 42,731.03
Year 18: 42,731.03 x 0.94 = 40,167.17
Year 19: 40,167.17 x 0.94 = 37,757.14
Year 20: 37,757.14 x 0.94 = 35,491.71
TOTAL: 1,360,629.60
Thus, rounded to the nearest whole number, the company caught 1,360,630 fish in total over the 20 years.
(a) 3.2% of 360 (b) 2.7% of 90 (c) 12.8% of 240 (d) 0.8% of 450 (e) 0.5% of 500 (f) 0.25% of 320

On a 28-question test, there are 2-point questions, 4-point questions, and 5-point questions. The test is worth a total of 100 points. There are twice as many 2-point questions as 5-point questions on the test. How many 2-point questions are on the test?
3.Write a series of equations that could be used to solve this. define your varbibles
4.Solveby any algebraic method. Work must be shown.
Answer:
The test has 8 questions of 2 points, as well as 16 of 4 points and 4 of 5 points.
Step-by-step explanation:
Since, on a 28-question test, there are 2-point questions, 4-point questions, and 5-point questions, the test is worth a total of 100 points and there are twice as many 2-point questions as 5- point questions on the test, to determine how many 2-point questions are on the test, the following calculation must be performed:
18 x 2 + 9 x 5 + 1 x 4 = 36 + 45 + 4 = 85
16 x 2 + 8 x 5 + 4 x 4 = 32 + 40 + 16 = 88
14 x 2 + 7 x 5 + 7 x 4 = 28 + 35 + 28 = 91
12 x 2 + 6 x 5 + 10 x 4 = 24 + 30 + 40 = 94
10 x 2 + 5 x 5 + 13 x 4 = 20 + 25 + 52 = 97
8 x 2 + 4 x 5 + 16 x 4 = 16 + 20 + 64 = 100
Thus, the test has 8 questions of 2 points, as well as 16 of 4 points and 4 of 5 points.
Suppose you deposit 900 dollars into a bank with 5% simple interest. The amount in the account after t years is given by A(t)=900(1.05)t (in dollars).
1. What is the average rate of change for the first year? Rate (in dollars per year): 900(1.05)-900
2. What is the average rate of change for the first five years? Rate (in dollars per year):
3. What is the average rate of change for the first ten years? Rate (in dollars per year):
4. Does the average rate of change increase or decrease as time from the initial deposit gets longer?
Answer:
1. 45 dollars per year.
2. 49.73 dollars per year.
3. 56.6 dollars per year.
4. Increases
Step-by-step explanation:
Average rate of change
The average rate of change of a function [tex]f(x)[/tex] over an interval [a,b] is given by:
[tex]A = \frac{f(b)-f(a)}{b-a}[/tex]
In this question, we have that:
[tex]A(t) = 900(1.05)^t[/tex]
1. What is the average rate of change for the first year?
[tex]A(0) = 900(1.05)^0 = 900[/tex]
[tex]A(1) = 900(1.05)^1 = 945[/tex]
So
[tex]A = \frac{A(1)-A(0)}{1-0} = \frac{945-900}{1-0} = 45[/tex]
45 dollars per year.
2. What is the average rate of change for the first five years?
[tex]A(0) = 900(1.05)^0 = 900[/tex]
[tex]A(5) = 900(1.05)^5 = 1148.65[/tex]
[tex]A = \frac{A(5)-A(0)}{5-0} = \frac{1148.65-900}{5-0} = 49.73[/tex]
49.73 dollars per year.
3. What is the average rate of change for the first ten years?
[tex]A(0) = 900(1.05)^0 = 900[/tex]
[tex]A(10) = 900(1.05)^{10} = 1466[/tex]
[tex]A = \frac{A(10)-A(0)}{10-0} = \frac{1466-900}{10-0} = 56.6[/tex]
56.6 dollars per year.
4. Does the average rate of change increase or decrease as time from the initial deposit gets longer?
From the previous items, it increases.

PLEASE HELP WITH THE FOLLOWING. WILL GIVE BRAINLIEST. THANK YOU
Answer:
50.8°Step-by-step explanation:
First, we need to use the Pythagorean Theorem to find the third side. We will then use the law of cosines to find the angle.
2√15² = 2√6² + b²
60 = 24 + b²
Subtract 24
36 = b²
b = 6
Now, that we have all three sides, we will use the law of cosines to figure out the angle.
c² = a² + b² - 2abCosC°
Substitute the values in.
6² = 2√15² + 2√6² - 2(2√15)(2√6)CosC°
36 = 60 + 24 - 2(37.947331922)CosC°
36 = 60 + 24 - 75.894663844CosC°
36 = 84 - 75.894663844CosC°
Subtract 84
-48 = -75.9CosC°
0.63241106719 = CosC°
Arccos (0.63241106719) = 50.77176844°
The largest acute angle is approximately 50.8°

Four pounds of apples cost $5. Eight pounds of apples cost $10. If the total cost of apples, y, varies directly with the number of pounds of apples purchased, x, what is the cost of 6 pounds of apples? Round your answer to the nearest hundredth.
$0.80
$1.25
$4.80
$7.50
Cost of apples, y, varies directly with pounds
of apples purchased, x.
y = kx
k is constant of proportion
Four pounds of apples cost $5
5 = 4k
k = 5/4 = 1.25
10 = 8k
k = 10/8 = 1.25
As it should be, k is a constant equal to 1.25
y = 6(1.25) = $7.50 for 6 pounds of apples

Evaluate the following
Lim (xcotx)
x->00
Answer:
1
Step-by-step explanation:
Evaluate the following
Lim (xcotx)
x->0
Note that cotx = cosx/sinx
The expression becomes
Lim (xcotx) = Lim (xcosx/sinx)
x->0 x->0
= 0cos0/sin0
= 0/0 )(ind)
Apply l'hospital rule
= Lim d/dx(xcosx/sinx)
x->0
= lim (-xsinx + cosx)/cosx
x->0
= -0sin0+cos0/cos0
= 0+1/1
= 1/1
= 1
Hence the limit of xcotx as x tends to zero is 1

An acre is equal to 43,560 square feet, and there are 5280 feet in a mile.
If a farm has the shape of a rectangle measuring 0.6 miles by 1.2 miles, what is the area of the farm in acres?
Answer:
=537.6 acres
Step-by-step explanation:
1 acre = 43560 ft^2
5280ft = 1 mile
Area of the farm
0.6miles×1.2miles = 3168ft×6336ft
=23,417,856ft^2
=23,417,856÷43560
=537.6 acres
