The function family sketched is exponential function.
From the graph, we can find certain values of the function for certain x-values.
When x = 0, the function has value 1.
When x = 2, the function has value 4
When x = 3, the function has value 8.
When x = 4, the function has value 16
From this we can identify the function as the exponential function, f(x) = eˣ
because e⁰ = 1. i.e., exponential function has value 1 when x = 0 which satisfy the sketch of the function given.
Also the other options given as piecewise function, linear function and quadratic function.
A piecewise function will not have a continuous sketch, but here the sketch of the function is continuous. So it cannot be a piecewise function. A linear function will have the sketch as a straight line, but here it is not. So it is not a linear function. The function values given in the sketch does not satisfy the quadratic function also.
So the only option is the sketch is of the exponential function.

What is 581/14 in partial quotients?
Answers
The quotient of 581 and 14 has a value of 40.07
How to evaluate the expression using partial quotients?The quotient expression is given as
581/14
Next, we express 581 as the sum of a multiple of 14 and another number
Say 581 = 280 + 280 + 1
So, we have the following equation
581/14 = (280 + 280 + 1)/14
Expand the bracket
So, we have the following equation
581/14 = 280/14 + 280/14 + 1/14
Evaluate the quotients
581/14 = 20 + 20 + 0.07

Use the Chain Rule to find ∂z/∂s and ∂z/∂t. (Enter your answer only in terms of s and t. Please use * for multiplication between all factors.)[tex]z = x^{7}y^{7}, x = s cos(t), y = s sin(t)[/tex]
Answers
Applying the Chain Rule, the derivatives are given as follows:
[tex]\frac{\partial z}{\partial s} = 7(s\cos{t})^6(s\sin(t))^6(y\cos{t} + x\sin{t})[/tex][tex]\frac{\partial z}{\partial t} = 7s(s\cos{t})^6(s\sin{t})^6(-y\sin{t} + x\cos{t})[/tex]What is the derivative of Z as a function of s?
The function Z is defined as follows:
z = x^7y^7.
The variables x and y are functions of variables s and t, as follows:
x = s cos(t).y = s sin(t).Hence the derivative of z as a function of s is given as follows:
∂z/∂s = (dz/dx)(dx/ds) + (dz/dy)(dy/ds).
Hence, applying the derivative rules for the exponents, and for the exponents, we have that:
[tex]\frac{\partial z}{\partial s} = 7x^6y^7\cos{(t)} + 7y^6x^7\sin{(t)} = 7x^6y^6(y\cos{t} + x\sin{t})[/tex]
Replacing the values of x and y, we have that:
[tex]\frac{\partial z}{\partial s} = 7(s\cos{t})^6(s\sin(t))^6(y\cos{t} + x\sin{t})[/tex]
What is the derivative of Z as a function of t?We follow the same logic as above, only that now the inside derivatives, that is, the derivatives of x and y, are as function of t and not of s, hence:
∂z/∂t = (dz/dx)(dx/dt) + (dz/dy)(dy/dt).
Then:
[tex]\frac{\partial z}{\partial t} = -7x^6y^7s\sin{(t)} + 7y^6x^7s\cos{(t)} = 7sx^6y^6(-y\sin{t} + x\cos{t})[/tex]
Then, replacing x and y as functions of s and t, we have that:
[tex]\frac{\partial z}{\partial t} = -7x^6y^7s\sin{(t)} + 7y^6x^7s\cos{(t)} = 7s(s\cos{t})^6(s\sin{t})^6(-y\sin{t} + x\cos{t})[/tex]

The value of a, b, c and d are 25, 3, 14 and 7 such that the sum of all rows, columns and diagonals are 48.
Given to us a magic square in which the sum of all rows, columns and diagonals are same. Then, we have to complete the missing numbers i.e., a, b, c and d respectively.
Let's proceed to solve this magic square accordingly.
First let's calculate that what will be the sum of all rows, columns and diagonals.
From the figure of magic square one diagonal is completely filled from that we can easily calculate the sum of the diagonals.
Sum = 5+16+27 = 48
Then, we can find the value of a, b, c and d easily.
5+a+18 = 48
23+a = 48
a = 48-23
a = 25
Therefore, the value of a is 25.
29+16+b = 48
45+b = 48
b = 48-45
b = 3
Therefore, the value of b is 3.
Now, 5+29+c = 48
34+b = 48
c = 48-34
c = 14
Therefore, the value of c is 14.
Then, we have
c+d+27 = 48
14+d+27 = 48
41+d = 48
d = 48-41
d = 7
Therefore, the value of d is 7.
Hence, we have completed the magic square in which the sum of all rows, columns and diagonals are 48.
Therefore, the value of a, b, c and d are 25, 3, 14 and 7 respectively.

What are the domain and range of the function?
For any function y = f(x), we define the domain as the set of the possible values of x (the ones on the horizontal axis) and the range is the set of the possible values of y (vertical axis).
In this case, we have a linear equation (you can see that the lines extend to the bottom left and the top right)

Answer:
21 Degrees.
Step-by-step explanation:
It was 22 degrees by noon, by then the temperature had already risen by
eight degrees, but since we are going back in time, we would subtract the eight degrees.
22 - 8 = 14.
Now we are at 9 A.M, it is 14 degrees. But, the temperature had doubled from 5-9 A.M, so we would divide our fourteen by two in order to half it.
14 ÷ 2 = 7.
Now we are at 5 A.M.
From midnight to 5 A.M the temperature dropped fourteen degrees so we would add that fourteen back into the equation.
7 + 14 = 21.

Which of the following are the coordinates of point F' , the image of point F, after a rotation of 90° about (1 point)
the origin?
Answers
Answer:
(3, 0)
Step-by-step explanation:
I assume this means a clockwise rotation.
let's think this through logically :
the last option (0, 3) cannot be right, because that is F before the rotation. to go back to the original position requires a full rotation of 360° (remember, a circle has 360°, and that means to travel one complete time around the circle).
(0, -3) cannot be right, because this is just mirrored down, and would represent a turn of 180° (a half-circle).
for the other options imagine you use a math compass, put the pin on the origin, and the writing arm on F. and the you draw a circle through F.
(3, 0) is the result of the clockwise (right) turn of 90°, (-3, 0) would be the result of a counterclockwise (left) turn of 90°.
so, if my assumption above is incorrect, please pick (-3, 0) for the counterclockwise solution.

What is a graph?In mathematics, a graph is a visual representation or diagram that shows data or values in an ordered way. The relationships between two or more things are frequently represented by the points on a graph. Bar graphs, circle graphs, and line graphs are the three most frequently used types of graphs.Different types of data can be displayed using different types of graphs.So, we are aware that a complex number is shown as:
z= x+iyWhere x stands for a number's real value and y for a number's imaginary value.
Which stands for the point (x,y)As a result, the number I is written as:
z=0+1.iThis indicates that the symbol for the number I is a point (0,1).
Therefore, the number I has a value of 1 on the hypothetical axis.So, Graph D is the appropriate selection.Therefore, graph (D) shows a complex number with an imaginary component, i.

For [tex]x_{6} = 2.1[/tex], [tex]f(x_{3} ) = 9 -2.1 = 7.2[/tex]
Now, The area by using an approximation using 6 approximating rectangles and right endpoints is given by.
A = Sum of [tex]f_{i}x'[/tex] = [tex](f_{1} + f_{2} + f_{3} + f_{4} + f_{5} + f_{6})x'\\[/tex]
A = (8.7 + 8.4 + 8.1 + 7.8 + 7.5 + 7.2)*0.3

Answers
After solving some mathematical operations we can conclude that the cashier has 16 bills of $10 and 18 bills of $20.
What do we mean by mathematical operations?A mathematical function called an operation, also known as an "operand" or "argument," transforms zero or more input values into a precisely defined output value.The quantity of operands affects the operation's arity.The operations that are most frequently studied are unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, and binary operations (i.e., operations of arity 2), such as addition and multiplication.An operation of arity zero also referred to as a nullary operation, is a constant.The mixed product is an illustration of an operation of arity 3, also referred to as a ternary operation.So, the total value of money by 35 bills is $0, and $20 is $520.
Now, we know that: 20 × 18 = 360Similarly, we know that: 10 × 16 = 160Sum of 360 and 160: 360 + 160 = $520So, 185 bills of $20 and 16 bills of $10.Therefore, after solving some mathematical operations we can conclude that the cashier has 16 bills of $10 and 18 bills of $20.
