Answer:
The answer is 70 moles
Step-by-step explanation:
For the farmer,
Total no of Moles = 330
No of marked moles with tags = 24
No of unmarked moles = 330 - 24 = 306
Few weeks later,
No of tagged moles found = 18
No of tagged moles not found,
= marked moles with tags - tagged moles found
= 24 - 18 = 6
Therefore, if for every 24 tagged moles, there are 6 moles found,
288 tagged moles = 24 X 12 (lots) = 288
For moles found = 6 X 12 (lots) = 72
To the nearest whole number,
The best estimate for the mole population would be 70 moles

Which trigonometric functions have a domain of [–1, 1]?
y = arcsinx and y = arccosx
y = arccosx and y = arctanx
y = arcsinx and y = arctanx
y = arcsecx and y = arccscx
Answer:
A
Step-by-step explanation:
Edge
The trigonometric functions y = arcsinx and y = arccosx have a domain of [–1, 1] option (A) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The domain of a trigonometric function is [-1, 1]
As we know,
The range of the sin x and cos x functions is [-1, 1]
The inverse of the above trigonometric functions are:
arc sin x and arc cos x
The range of sin x and cos x becomes domain.
So the domain of y = arcsinx and y = arccosx is [-1, 1].
Thus, the trigonometric functions y = arcsinx and y = arccosx have a domain of [–1, 1] option (A) is correct.

Suppose you just deposited $500 into a bank account that has earned 5% interest on the amount you initially
invested. If the new balance is $1,760, what was your initial investment?
Answer:
$1200
Step-by-step explanation:
Let the initial amount that you invested be $ x.
We are told that the new balance after investing $500 is $1760.
Thus, the balance you had before the deposit $500 us;
$1760 - $500 = $1260
So, when the amount invested was $x, the balance was $1260.
Since this money earned 5% interest on the amount you initially
Thus;
$1260 = initial deposit + (5% of inital deposit)
Thus;
x + (5% * x) = 1260
x + (0.05x) = 1260
1.05x = 1260
x = 1260/1.05
x = $1200

what is the number which is to be added with 49x square + 4y square to get a perfect square
Answer:
The number which should be added with 49x square + 4y square to get a perfect square is 28xy
Step-by-step explanation:
We need to find the number which is to be added with 49x square + 4y square to get a perfect square.
The expression given is: [tex]49x^2+4y^2[/tex]
For the expression to be perfect square it should be of form: [tex]a^2+2ab+b^2=(a+b)^2[/tex]
Now, we are given [tex]49x^2+4y^2[/tex] and we need to find the middle term
So, solving:
[tex]49x^2+4y^2\\=(7x)^2+(2y)^2+2(7x)(2y)-2(7x)(2y)\\=7x^2+28xy+(2y)^2-28xy\\=(7x+2y)^2-28xy[/tex]
The number which should be added with 49x square + 4y square ([tex]49x^2+4y^2[/tex]) to get a perfect square is 28xy

If the coordinates of point a are (-2 3) what is the image of a under y-axis d3
Answer:
The coordinates of the image under the y-axis will be:
a'(2, 5)Step-by-step explanation:
Given the point
(2,3)We know that when we reflect a point across the y-axis, the y-coordinate remains the same, but the x-axis reverses its sign.
Thus,
Rule of reflection under y-axis:
P(x, y) → P'(-x, y)
Here, P'(x, y) is the image of the P(x, y)
Given that the point
a(-2, 5)Thus, the coordinates of the image under the y-axis will be:
(x, y) → (-x, y)
a(-2, 5) → a'(-(-2), 5) = a'(2, 5)
Therefore, the coordinates of the image under the y-axis will be:

An initial population of 460 quail increases at an annual rate of 21%. Write an exponential function
to model the quail population. What will the approximate population be after 3 years?
Answer:
the expected population after 3 years is 863.7009
Step-by-step explanation:
The computation of the expected population after 3 years is shown below
P = P_0 × e^rt
where,
r = 21% = 0.21
t = 3 years
P_0 = 460
Now place these values to the above formula
P = 460 × exp(0.21 × 3)
= 863.7009
hence, the expected population after 3 years is 863.7009
We simply applied the above formula so that the correct value could come

Which of the following numbers are perfect . 3364,4489,4358 please solve
Answer:
Below
Step-by-step explanation:
A perfect number is one whose proper divisors add up to that number.
For example, 6 is a perfect number because
Its proper divisors 1, 2 and 3 and 1+2+3 = 6.
First list prime factors:
3364 = 2 * 2 * 29 * 29
Proper divisors are 1, 2, 4, 29, 58, 116, 841, 1682
Sum of these = 2733.
So, 3364 is not a perfect number.
4489 = 67 * 67
Divisors are 1 and 67.
Sum = 68.
So, 4489 is not a perfect number.
4358 =2 * 2179
Divisors are 1 , 2 and 2179.
Sum = 2182.
So, 4358 is not a perfect number.

Step-by-step explanation:
h(x) = 3. g(x) + 5
x= -1 h(x) = 3×8 + 5= 29
x= 0h(x) = 3×5 + 5= 20
x= 2 h(x) = 3×1 + 5= 8
x= 5 h(x) = 3×-5 + 5= -10
[tex]h(x) = 3*g(x)+5[/tex]
When x = -1.
Substitute x = -1 in both h(x) and g(x). | As shown in the table, when x = -1, g(x) = 8 |
h(-1) = 3*8+5 = 24+5 = 29
h(0) = 3*5+5 = 15+5 = 20
h(2) = 3*1+5 = 3+5 = 8
h(5) = 3*(-5)+5 = -15+5 = -10

b. y= -x - 4
c. y = x - 4
d. y = x +1
7. The table below represents a linear function. What is the slope of this function?
a. 1/3
b. -1/3
c. 3
d. -3
Answer:
Step-by-step explanation:
1. Slope = (y2-y1) / (x2-x1) = -3-0/ -1-4= -3/-5= 3/5 (d)
2.
Compare to the equation y= mx+b, where m is the slope
3y = 15x+9 divide by 3 each term
y = 15x/3 +9/3
y= 5x + 3 so slope is 5 ( a)
3.
use first the equation point- slope y-y1 =m (x-x1) and rearange it to be in slope-intercept form y=mx +b
y-y1 =m (x-x1)
y-2 = -3( x-1)
y = 2-3x+3
y= -3x +5 ( c)
4.
if the point y- intercept is at (0, 3) then the y-intercept is b=3
y= mx+b
y = 2x +3 (a)
5.
the equation point- slope y-y1 =m (x-x1), find the slope m= (y2-y1) / (x2-x1)
m= 3-12/ 1+2 = -9/3 = -3
y-1 = -3(x-3) is (a)
6.
y-intercept is at -4 ( yet the graph is off a bit -tell your teacher)
slope m = 1
so the equation is y=mx+b and here is y=x -4 (c)
7.
the slope is m= (y2-y1) / (x2-x1) si pich any two points from the table and calculate the slope
for example (0, 3) and (1, 0)
m = (3-0)/ (0-1) = 3/-1 = -3 (d)
1. Slope = (y2-y1) / (x2-x1) = -3-0/ -1-4= -3/-5= 3/5 (d)
2.
Compare to the equation y= mx+b, where m is the slope
3y = 15x+9 divide by 3 each term
y = 15x/3 +9/3
y= 5x + 3 so slope is 5 ( a)
3.
use first the equation point- slope y-y1 =m (x-x1) and rearange it to be in slope-intercept form y=mx +b
y-y1 =m (x-x1)
y-2 = -3( x-1)
y = 2-3x+3
y= -3x +5 ( c)
4.
if the point y- intercept is at (0, 3) then the y-intercept is b=3
y= mx+b
y = 2x +3 (a)
5.
the equation point- slope y-y1 =m (x-x1), find the slope m= (y2-y1) / (x2-x1)
m= 3-12/ 1+2 = -9/3 = -3
y-1 = -3(x-3) is (a)
6.
y-intercept is at -4 ( yet the graph is off a bit -tell your teacher)
slope m = 1
so the equation is y=mx+b and here is y=x -4 (c)
7.
the slope is m= (y2-y1) / (x2-x1) si pich any two points from the table and calculate the slope
for example (0, 3) and (1, 0)
m = (3-0)/ (0-1) = 3/-1 = -3 (d)
