Values for relation g
Find
Which pair is in g inverse.
Explanation
In the inverse function , it satisfies when y = f(x)
[tex]x=f^{-1}(y)[/tex]so , in the inverse of g
since g(4) = 9 , so
[tex]4=g^{-1}(9)[/tex]g(5) = 13 , so
[tex]13=g^{-1}(5)[/tex]g(3) = 5 , so
[tex]5=g^{-1}(3)[/tex]g(2) = 2 , so
[tex]2=g^{-1}(2)[/tex]so , (13 , 5) would be found in the inverse of g
Final Answer
Hence , the correct option is (13 , 5)

1
2. Write the GCF: 1
3. Rewrite expression factor out the GCF: 16y + 5
4. Write the final factored expression: 16y + 5
Explanation:
The initial expression is:
16y + 5
So, we have two terms: 16y and 5
The factors of these terms are:
16y: 1, 2, 4, 16, y, 2y, 4y, 16y
5: 1, 5
So, the greatest common factor is 1
Then, the expression factor out the GCF is:
[tex]\frac{16y+5}{1}=16y+5[/tex]Therefore, the final factored expression is:
1*(16y + 5) = 16y + 5

The slope-intercept form is
[tex]y=mx+b[/tex]m is the slope
b is the y-intercept
The rule of the slope of a line that passes through points (x1, y1) and (x2, y2) is
[tex]m=\frac{y2-y1}{x2-x1}[/tex]From the given graph, the line passes through points (1, -4) and (0, 2)
Let (x1, y1) = (1, -4) and (x2, y2) = (0, 2)

Mutually exclusive events:
Two events are mutually exclusive if they cannot occur at the same time.
There are 52 cards in a deck of cards.
n(s)=52.

n(A)=4.
So, Probability of getting jack is,

Let
x ------> the number of ounces of frozen yogurt
y ------> the total charge
we have the ordered pairs
(3.6,4.47) and (4.8,5.01)
step 1
Find the slope pr unit rate
m=(5.01-4.47)/(4.8-3.6)
m=$0.45 per ouncestep 2
Find the equation in point slope form
y-y1=m(x-x1)
we have
m=0.45
(x1,y1)=(3.6,4.47)
substitute
y-4.47=0.45(x-3.6)

Let's first conceptualize the given details by drawing a rectangle with the given details being reflected.
Where,

What is the value of the algebraic expression if x = 1/2, y = -1, and z = 2?Here is the algebraic expression: 6x(y to second power z)
Answers
The value of the algebraic expression if x = 1/2, y = -1, and z = 2 is 6.
The given expression is [tex]6xy^{2}z[/tex] and we need to evaluate its value when x = 1/2, y = -1, and z = 2
Simply assign the values of each variable to the variables in the algebraic expression and evaluate the result to get the value of the expression. What we do is:
[tex]6xy^{2}z\\\\=6 * \frac{1}{2}*(-1)^{2} *2 \\\\=6 * \frac{1}{2}*1 *2\\\\=6[/tex]
The algebraic expression's value would be 6, then. In an algebraic expression, the variables are denoted by letters, in this case x, y, and z; the coefficients are denoted by numbers, such as 6, and the exponents are, in this case, 2, as in the expression above. Expressions frequently include several terms made up of those components.

[tex]\begin{gathered} (x,\text{ y\rparen }\rightarrow\text{ \lparen x, -y\rparen} \\ We\text{ will negate all the y values of the vertices above while keeping x coordinate constant} \\ A\text{ = \lparen-4, -8\rparen} \\ B\text{ = \lparen-8, -4\rparen} \\ C=\text{ \lparen0, -0\rparen = \lparen0, 0\rparen} \end{gathered}[/tex]c) dilate by 1/2
[tex]\begin{gathered} (x,\text{ y\rparen }\rightarrow(\frac{1}{2}x,\text{ }\frac{1}{2}y) \\ We\text{ will multiply the coordinates above by 1/2 in both the x and y coordinates} \\ A^{\prime}\text{ = \lparen}\frac{1}{2}(-4),\text{ }\frac{1}{2}(-8))\text{ = \lparen-2, -4\rparen} \\ B^{\prime}\text{ = \lparen}\frac{1}{2}(-8),\text{ }\frac{1}{2}(-4))\text{ = \lparen-4, -2\rparen} \\ C^{\prime}\text{ = \lparen}\frac{1}{2}(0),\text{ }\frac{1}{2}(0))\text{ = \lparen0, 0\rparen} \\ \\ Image\text{ of ABC: A' \lparen-2, -4\rparen, B' \lparen-4, -2\rparen and C' = \lparen0, 0\rparen} \end{gathered}[/tex]d) To determine if the area of the pre-image is greater or less than, we will plot the coordinates of both triangles:
Since the triangle of the Image is greater than the triangle of the pre-image (original figure), then the area of the pre- image will be less than the new image
e) For two triangles to be congruent, the sides and angles for both triangles will be equal
For two triangles to be similar, the ratio of their corresponding sides will be equal
The image A'B'C' is a scaled triangle of ABC. This mean the sides can't be equal but the ratio fo their corresponding sides will be equal.
Hence, it is simlar

Determine the initial investment, PV, for a future value of 6500 dollars if the nominal rate of interest is 5.9 percent compounded quarterly for 12 years? FV = PV(1 + r/n) ^ntPv = ________ (Be sure to give 2 decimal places of accuracy.)
Answers
Answer: PV = 3218.69
Explanation:
The formula for calculating compound interest is expressed as
FV = PV(1 + r/n) ^nt
Where
FV is the future value
PV is the initial value
r is the interest rate
n is the number of compounding periods in a year
t is the number of years
From the information given,
FV = 6500
r = 5.9% = 5.9/100 = 0.059
n = 4 because it was compounded quarterly
t = 12
By substituting these values into the formula,
6500 = PV(1 + 0.059/4)^4 * 12
6500 = PV(1.01475)^48
PV = 6500/(1.01475)^48
PV = 3218.69
