This sequence represents the diameters of circles used to create an art project: 2.5 cm, 3.1 cm, 3.7 cm, 4.3 cm Let f(n) represent diameter in centimeters and n the term number in the sequence. Which equation represents the sequence of diameters?
Answer:
[tex]f(n) = 1.9 +0.6n[/tex]
Step-by-step explanation:
The nth term of the arithmetic sequence is given by:
[tex]a_n = a_1+(n-1)d[/tex] ....[1]
where
[tex]a_1[/tex] is the first term
d is the common difference and n is the number of terms.
Here, f(n) represent diameter in centimeters and n the term number in the sequence.
Given the sequence represents the diameters of circles used to create an art project:
2.5 cm, 3.1 cm, 3.7 cm , 4.3 cm
This sequence is an arithmetic sequence with
[tex]a_1[/tex] = 2.5 and d = 0.6
Since,
3.1-2.5 = 0.6,
3.7-3.1 = 0.6
4.3-3.7 = 0.6
Substitute the given values in [1] we have;
[tex]f(n) =2.5+(n-1)(0.6)[/tex]
Using distributive property, [tex]a\cdot (b+c) = a \cdot b+ a\cdot c[/tex]we have;
[tex]f(n) = 2.5+0.6n-0.6[/tex]
Simplify:
[tex]f(n) = 1.9 +0.6n[/tex]
Therefore, the equation represents the sequence of diameters is, [tex]f(n) = 1.9 +0.6n[/tex]
how many three digit positive integers are there such that the three digits are 3, 4, and 8?
The product of two consecutive even positive integers is 674 more than the sum of the two integers. Find the integers.
The equation is A ( A + 2 ) = 674 + ( A + ( A + 2 ) )
The first integer is A = 26
The second integer is B = 28
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the two numbers be A and B
where , the first integer is = A
The second integer is = B
B is the consecutive integer of A , so
The value of B = A + 2
Now , the equation will be
The product of two consecutive even positive integers is 674 more than the sum of the two integers
So , substituting the values in the equation , we get
A ( A + 2 ) = 674 + ( A + ( A + 2 ) )
On simplifying the equation , we get
A² + 2A = 674 + 2A + 2
Subtracting 2A on both sides of the equation , we get
A² = 674 + 2
A² = 676
Taking square roots on both sides of the equation , we get
A = 26
The value of B = A + 2
B = 28
Therefore , the value of A = 26
The value of B = 28
Hence ,
The first integer is A = 26
The second integer is B = 28

A local hamburger shop sold a combined total of 646 hamburgers and cheeseburgers on Saturday. There were 54 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Saturday?
646-54 = 592
592/2 = 296
296+54 = 350
350+296 = 646
there were 350 hamburgers and 296 cheeseburgers sold
Which of the following statements is always true?
A All integers are counting numbers.
B All rational numbers are integers.
C All integers are whole numbers.
D All counting numbers are whole numbers.
D. All counting numbers are whole numbers.
All integers are counting numbers. This is not true. Counting numbers (also known as natural numbers) are positive whole numbers starting from 1, 2, 3, and so on. Integers include all positive and negative whole numbers, as well as zero. Thus, not all integers are counting numbers.
All rational numbers are integers. This is not true. Rational numbers include all fractions where the numerator and denominator are integers (denominator not zero). For example, 1/2 is a rational number but not an integer.
All integers are whole numbers. This is not true. Whole numbers include all non-negative integers (0, 1, 2, 3, ...), but integers also include negative numbers, which are not whole numbers.
Counting numbers (1, 2, 3, ...) are included in the set of whole numbers, which consists of all non-negative integers (0, 1, 2, 3, ...).

(09.01) The function below shows the number of car owners f(t), in thousands, in a city in different years t: f(t) = 0.25t2 − 0.5t + 3.5 The average rate of change of f(t) from t = 2 to t = 6 is ______ thousand owners per year.
Answer: The average rate of change of f(t) from t = 2 to t = 6 is 1.5 thousand owners per year.
Step-by-step explanation:
Given: The function below shows the number of car owners f(t), in thousands, in a city in different years t:
[tex]f(t) = 0.25^2 - 0.5t + 3.5[/tex]
Now,
[tex]f(2) = 0.25(2)^2 - 0.5(2) + 3.5=3.5\\\\= f(6) = 0.25(6)^2-0.5(6)+ =9.5[/tex]
Now, the average rate of change of f(t) from t = 2 to t = 6 is given by :-
[tex]k=\dfrac{f(6)-f(2)}{6-2}\\\\=\dfrac{9.5-3.5}{4}=1.5[/tex]
Hence, the average rate of change of f(t) from t = 2 to t = 6 is 1.5 thousand owners per year.

Consider the following sets. U = {ordered pairs on a coordinate plane} A = {ordered pair solutions to y = x} B = {ordered pair solutions to y = 2x} Which ordered pair satisfies A ∩ B?
Answer:
(0,0)
Step-by-step explanation:
We have,
U = { (x,y) : x,y belong to real numbers }
A = { (x,y) : (x,y) is a solution of y=x }
B = { (x,y) : (x,y) is a solution of y=2x }
We need to find the ordered pair (x,y) that belong to A[tex]\bigcap[/tex]B.
Let, (x,y) belong to A[tex]\bigcap[/tex]B
i.e. (x,y) belong to A and (x,y) belong to B
i.e. y = x and y = 2x
i.e. x = 2x
i.e. x = 0
Now, substitute x= 0 in any of the equation say y = x, we get y = 0.
Hence, the ordered pair satisfying A[tex]\bigcap[/tex]B is (0,0).
For a set U, The ordered pair satisfies A ∩ B is mathematically given as
x = 0, y = 0 (0,0)
Which ordered pair satisfies A ∩ B?Question Parameter(s):
U = {ordered pairs on a coordinate plane}
A = {ordered pair solutions to y = x}
B = {ordered pair solutions to y = 2x}
if (x,y) belongs to AnB
y = x and y = 2x
x = 0
In conclusion, subsituting we have
y = x and y = 2x
y = 0

The area of a circle is a function equal to the product of pi (pi) and the square of the radius (r). Which of the following shows this function?
The function for the area of the circle if x is the radius of the circle and y is the area of the circle is y = πx².
What is area?An object's area is how much space it takes up in two dimensions. It is the measurement of the number of unit squares that completely cover the surface of a closed figure.
Given:
The area of a circle is a function equal to the product of pi (pi) and the square of the radius (r),
The area of the circle can be written as shown below,
Area of circle = π × R²
Here π is a constant, R is the radius of the circle,
When we put the value of the radius, we will get the value of the area,
Hence, the radius is an independent function and the area is dependent on the value of R (dependent function),
Replace y with area and radius with x as shown below,
y = πx²
Thus, y = πx² is the function for the area of the circle.

True or False? The point-slope form of a line is y + y1 = m(x + x1), where m is the slope and (x1, y1) is a point on the line. It's false right?
Answer:
False
The correct point slope form passing through points (x1,y1) is [tex](y-y1)=m (x-x1)[/tex] .
Step-by-step explanation:
The formula for the point slope form passing through the point (a,b) is given by.
[tex](y-b)=m (x-a)[/tex]
Where m is the slope .
As given in the question.
m is the slope and (x1, y1) is a point on the line.
Thus the point slope form becomes
[tex](y-y1)=m (x-x1)[/tex]
Therefore the correct point slope form passing through points (x1,y1) is [tex](y-y1)=m (x-x1)[/tex] .
