How do you show that f and G are inverses of each other?
First make the graph of the functions, then if the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions.
Symmetric
A figure or shape that can be divided into two equal parts by a line is called symmetric figures.
Inverse Functions
The inverse function of a function f is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by F^-1.

suppose the length of maize ears has narrow sense heritability (h2) ( h 2 ) of 0.70. a population produces ears that have an average length of 28 cm c m , and from this population a breeder selects a plant producing 34- cm c m ears to cross by self-fertilization.
We can expect the mean length of ears in the next generation to be 31.6 cm.
It is given that the narrow sense heritability (h2) is 0.70, which means that 70% of the total variation in maize ear length is due to genetic factors.
Let the mean length of ears in the original population be µ and the mean length of ears in the selected plant be x. Then, we can use the formula for response to selection to find the expected mean length of ears in the next generation:
x' = µ + h2 * (x - µ)
Substituting the given values, we get:
x' = 28 + 0.70 * (34 - 28) = 31.6 cm
Therefore, we can expect the mean length of ears in the next generation to be 31.6 cm.

Can you solve for each variable? (x, y, and z)
Answer:
x = 103
y = 103
z = 33
Step-by-step explanation:
The sum of all three interior angles is 180 degrees.
180 - 29 - 48 = 103
x = 103
The vertical angles are always congruent, so x = y.
y = 103
180 - 44 - 103 = 33
z = 33
Ramon drew boxplots to summarize the number of pages in each chapter of two books. The values of the interquartile ranges for these boxplots are the same. Which boxplot could represent this data?
Answer
look at the ss i sent to see the answer
Step-by-step explanation:
Find the distance from the point to the line. 33. (0, 0, 12); x = 4t, y = -2t, z = 2t
The distance from the point (0, 0, 12) to the line x = 4t, y = -2t, z = 2t is (8√15) / 3.
The distance from the point (0, 0, 12) to the line defined by x = 4t, y = -2t, z = 2t can be found using the formula for the distance between a point and a line in three-dimensional space.
The formula is given by:
Distance = |(P - Q) × V| / |V|,
where P is a point on the line, Q is the given point, V is the direction vector of the line, and × denotes the cross product.
In this case, we can choose any point on the line to represent P. Let's choose P as (4, -2, 2). The direction vector of the line is V = (4, -2, 2).
Using the formula, we can calculate the distance as follows:
Distance = |((0, 0, 12) - (4, -2, 2)) × (4, -2, 2)| / |(4, -2, 2)|.
Simplifying the expression, we get:
Distance = |(-4, 2, 10) × (4, -2, 2)| / |(4, -2, 2)|.
To find the cross product, we can use the determinant method:
((-4, 2, 10) × (4, -2, 2)) = [(2 * 2 - 10 * -2), (10 * 4 - (-4) * 2), ((-4) * (-2) - 2 * 4)]
= (4 - 20, 40 - (-8), 8 - 8)
= (-16, 48, 0).
Now we can substitute the values back into the distance formula:
Distance = |(-16, 48, 0)| / |(4, -2, 2)|.
Taking the magnitude of the vectors, we get:
Distance =\(\sqrt((-16)^2 + 48^2 + 0^2) / √(4^2 + (-2)^2 + 2^2)\)
= √(256 + 2304 + 0) / √(16 + 4 + 4)
= √2560 / √24
= 16√10 / 2√6
= 8√10 / √6
= (8√10 / √6) * (√6 / √6)
= (8√60) / 6
= (8√15) / 3.

If the number of bacteria on the surface of your phone triples every hour and can be described by the exponential function: f(x)=1000x3^x
, complete the table of values to show how much bacteria is on your phone after 4 hours.
Answer: 81,000
Step-by-step explanation:
We can solve this by using the formula given.
If f(1)=1000x3^1, then 1,000x3=3,000
If f(2)=1000x3^2, then 3^2=9 and 1000x9=9000,
and so on,
Now, f(4) will equal 1000x3^4, and 3^4 is 3x3x3x3, which is 9x9 or 9^2, which would be equal to 81, and 81x1000=81,000
To complete the table of values for the exponential function f(x) = 1000*3^x, we can evaluate the function for x = 0, 1, 2, 3, and 4, since we are interested in the number of bacteria on the phone after 4 hours.
x f(x)
0 1000
1 3000
2 9000
3 27,000
4 81,000
Therefore, after 4 hours, there will be 81,000 bacteria on the surface of the phone, assuming the number of bacteria triples every hour and can be described by the exponential function f(x) = 1000*3^x.

The curve of best fit is an illustration of a quadratic regression
The equation of the curve of best fit is \(y = -\frac{17}{18}x^2 + \frac{17}3x + 2\), and the height of the frog after 6 seconds is 2 feet
How to determine the equation of the curve of best fit?To determine the equation of the curve of best fit, we make use of a graphing calculator
Using the graphing calculator, we have the following calculation summary
a = -17/18b = 17/3c = 2The equation of the curve of best fit is represented as:
\(y = ax^2 + bx + c\)
Substitute the values for a, b and c.
So, we have:
\(y = -\frac{17}{18}x^2 + \frac{17}3x + 2\)
After 6 seconds, the value of x is 6.
So, we have:
\(y = -\frac{17}{18} * 6^2 + \frac{17}3 * 6 + 2\)
Evaluate
\(y = 2\)
Hence, the height of the frog after 6 seconds is 2 feet

Solve by forming a quadratic equation. 1. Two numbers, which differ by 3, have a product of 88. Find them.
Answer:
Step-by-step explanation:
x*(x-3) = 88x^2-3x-88 = 0-b+- √(b^2-4ac)/2a3+-√(9-4(1)(-88)/23+- √(9+352)/2a3+-√361/2a3+19/2 or 3-19/221/2 ir -16/2S.S = {21/2,-8}2 numbers that differ by 3 and have a product of 88 are 11 and 8.
Let's say that the very first figure is x and the next is y.
x - y = 3 -----> y=x-3 .........(i)
xy=88 .......(ii)
Substitute (i) to (ii)
xy=88
x(x-3)=88
x\(x^{2} - 3x = 88\\x^{2} - 3x - 88 = 0\)
(x+8)(x-11)=0
x+8=0 or x-11=0
x=-8 or x=11
Substitute x=-8 to (i)
y=x-3
y=-8-3=-11
Substitute x=11 to (i)
y=x-3
y=11-3=8
Thus, x = -8 and y =- 11 or x = 11 and y = 8
2 numbers that differ by 3 and have a product of 88 are 11 and 8.

Suppose f(x, y, z) = x2 + y2 + z2 and W is the solid cylinder with height 5 and base radius 6 that is centered about the z-axis with its base at z : -1. Enter O as theta. - (a) As an iterated integral, F sav = 10% x^2+y^2+z12 dz dr de W with limits of integration A = 0 B = C= 0 D= 6 E = -1 F = (b) Evaluate the integral.
∫_A^B ∫_B^C ∫_D^E (10%)(x^2 + y^2 + z^12) dz dr dθ.
This represents the full iterated integral for F_sav over the given solid cylinder.
(a) The iterated integral for F_sav with the given limits of integration is as follows:
∫∫∫_W (10%)(x^2 + y^2 + z^12) dz dr dθ,
where the limits of integration are A = 0, B = C = 0, D = 6, and E = -1.
(b) To evaluate the integral, we begin with the innermost integration with respect to z. Since z ranges from -1 to 6, the integral becomes:
∫∫_D^E (10%)(x^2 + y^2 + z^12) dz.
Next, we integrate with respect to r, where r represents the radial distance from the z-axis. As the solid cylinder is centered about the z-axis and has a base radius of 6, r ranges from 0 to 6. Thus, the integral becomes:
∫_B^C ∫_D^E (10%)(x^2 + y^2 + z^12) dz dr.
Finally, we integrate with respect to θ, where θ represents the angle around the z-axis. As the cylinder is symmetric about the z-axis, we integrate over a full circle, so θ ranges from 0 to 2π. Hence, the integral becomes:
∫_A^B ∫_B^C ∫_D^E (10%)(x^2 + y^2 + z^12) dz dr dθ.
This represents the full iterated integral for F_sav over the given solid cylinder.
The problem asks for the iterated integral of F_sav over the solid cylinder W. To evaluate this integral, we use the cylindrical coordinate system (r, θ, z) since the cylinder is centered about the z-axis. The function inside the integral is 10% times the sum of squares of x, y, and z^12. By integrating successively with respect to z, r, and θ, and setting appropriate limits of integration, we obtain the final iterated integral. The integration limits are determined based on the given dimensions of the cylinder.

How many numbers among 1000-2000 are multiples of any two but not three of the first three odd prime numbers?
Hint: the first three odd prime numbers are 3,5,7
Answer: The first three odd prime numbers are 3, 5, and 7. A number is a multiple of two but not three of these prime numbers if it is divisible by two of them, but not the third.
To find the number of numbers between 1000 and 2000 that are multiples of two but not three of the first three odd prime numbers, we can count the number of multiples of each pair of prime numbers and subtract the number of multiples of all three prime numbers.
There are 200 multiples of 3 and 5 between 1000 and 2000 (200 numbers for each, for a total of 200 * 2 = 400). There are 133 multiples of 3 and 7 between 1000 and 2000 (133 numbers for each, for a total of 133 * 2 = 266). There are 80 multiples of 5 and 7 between 1000 and 2000 (80 numbers for each, for a total of 80 * 2 = 160). There are no multiples of all three prime numbers between 1000 and 2000.
Thus, the total number of numbers between 1000 and 2000 that are multiples of two but not three of the first three odd prime numbers is 400 + 266 + 160 = 826.

At the neighborhood playground, your friend sits on a swing and gets pulled back by you to the highest point that you can reach. When you let go, your friend rides the swing without receiving or providing additional push. Your friend travels along an arc of 14 feet on the first swing (back to front). As the swing comes backwards, the length of the arc is .80 of the previous swing. This continues: each successive arc created by swinging is .80 of the previous swing.

Answer:
5th swing: 5.734 ft13 swing is less than 1 ft66.152 feet traveled in 13 swingsStep-by-step explanation:
The sequence of arc lengths is a geometric sequence with first term 14 ft and common ratio 0.8. The general (n-th) term of such a sequence is given by ...
an = a1 · r^(n-1) . . . . . . . first term a1, common ratio r
For this scenario, the n-th term is ...
an = 14·0.8^(n-1)
__
a.The 5th term is ...
a5 = 14·0.8^(5-1) ≈ 5.734 . . . . feet
__
b.For the arc length to be less than 1 ft, we require ...
14·0.8^(n-1) < 1
0.8^(n-1) < 1/14
(n -1)log(0.8) < log(1/14) . . . . . . note that these log values are negative
n -1 > log(1/14)/log(0.8)
n > 1 +log(1/14)/log(0.8) ≈ 12.8
The 13th swing will have an arc length less than 1 ft.
__
c.The sum of n terms of a geometric sequence is given by ...
Sn = a1 · (1 -r^n)/(1 -r)
13 terms of our sequence will total ...

What is the solution to the system of linear equations?
Answer:
(0,2)
Step-by-step explanation:
The equations must be derived from the graph:
First, find the slope of f(x):
\(m=\frac{y_2-y_1}{x_2-x_1}\) let \((x_1,y_1)=(-3,3)\) and \((x_2,y_2)=(3,1)\)
\(m=\frac{(1)-(3)}{(3)-(-3)}\\m=\frac{-2}{6}\\m=-\frac{1}{3}\)
Then use \(y-y_1=m(x-x_1)\)
\(y-3=-\frac{1}{3}[x-(-3)]\\y-3=-\frac{1}{3}x-1\\y=-\frac{1}{3}x+2\\f(x)=-\frac{1}{3}x+2\)
For g(x), let:
\((x_1,y_1)=(-3,0)\\(x_2,y_2)=(0,2)\)
\(m=\frac{(2)-(0)}{(0)-(-3)}\\m=\frac{2}{3}\)
\(y-0=\frac{2}{3}[x-(-3)]\\y=\frac{2}{3}x+2\\g(x)=\frac{2}{3}x+2\)
Now, to solve for x, allow the two expressions written in terms of x equal each other.
\(-\frac{1}{3}x+2=\frac{2}{3}x+2\\(-\frac{1}{3}x+2)+\frac{1}{3}x=(\frac{2}{3}x+2)+\frac{1}{3}x\\2=x+2\\(2)-2=(x+2)-2\\x=0\)
To solve for y, substitute 0 for x in f(x):
\(y=-\frac{1}{3}x+2\\y=-\frac{1}{3}(0)+2\\y=0+2\\y=2\)
So, the solution to this system of equations would be the ordered pair (0,2). This solution is seen on the graph as the intersection of the two lines.

Firm has a loss level EBIT of $175m and an expected EBIT of $200m with a standard deviation of $50m.
Z-score = (EBIT - Expected EBIT) / Standard deviation= (175 - 200) / 50= -0.5
Probability of having a negative EPS:
To find the probability that the firm will have a negative EPS, we need to find the area to the left of Z-score. As the Z-score is negative, we will be finding the left-tail probability using the standard normal table from the link below:
The area to the left of Z-score (0.5) is 0.3085 or 30.85%.
Therefore, the probability that the firm WILL have a negative EPS is 30.85%.
