Answer:
The nth term of the sequence is:
[tex]a_n=\frac{-3n+3}{2}+8[/tex]
Step-by-step explanation:
Given the first 5 terms of the arithmetic sequence
8, 13/2, 5, 7/2, and 2
An arithmetic sequence has a constant difference 'd' and is defined by:
[tex]a_n=a_1+\left(n-1\right)d[/tex]
as the common difference 'd' is:
[tex]d=a_{n+1}-a_n[/tex]
Computing the differences of all the terms
[tex]\frac{13}{2}-8=-\frac{3}{2},\:\quad \:5-\frac{13}{2}=-\frac{3}{2},\:\quad \frac{7}{2}-5=-\frac{3}{2},\:\quad \:2-\frac{7}{2}=-\frac{3}{2}[/tex]
[tex]d=-\frac{3}{2}[/tex]
The first element is:
[tex]a_1=8[/tex]
Therefore, the nth term is computed by:
[tex]a_n=a_1+\left(n-1\right)d[/tex]
[tex]a_n=-\frac{3}{2}\left(n-1\right)+8[/tex]
[tex]a_n=\frac{-3n+3}{2}+8[/tex]
Therefore, nth term of the sequence is:
[tex]a_n=\frac{-3n+3}{2}+8[/tex]
A principal at a large high school wants to estimate the number of days freshmen regularly ride the bus to school.

Answer: 2.5
[tex]\frac{p}{a}=\frac{1}{2} => a=2p\\\\\frac{a}{b}=\frac{2}{3}=> b=\frac{3}{2}a=3p\\\\\frac{b}{c}=\frac{5}{1}=>c=\frac{1}{5} b=\frac{3p}{5}\\\\\frac{c}{r}=\frac{3}{2}=>\frac{3p}{5r}=\frac{3}{2}=>\frac{p}{r}=\frac{3}{2}:\frac{3}{5}=2.5[/tex]

Answer:
y = 3x-5
Step-by-step explanation:
this is becuase the y-intercept of these points falls to around -5 (a point actually crosses the y axis at -5)
the gradient of these points is too steep to be x and the slope is not negative - therefore the slope must match closest to 3x.

A fish is swimming at a vibrant rate toward the ocean floor. The equation y=-7x-3 can be used to represent this distinction, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming. Which statement best describes the depth of the fish,given this equation.
A.From a starting position of 7 meters below sea level, the fish is descending 3 meters per second.
B.From a starting position of 7 meters below sea level, the fish is ascending 3 meters per second .
C.From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.
D.From a starting position of 3 meters below sea level, the fish is ascending 7 meters per second.
Answer:
C. From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.
Answer:
C
Step-by-step explanation:
y = -7x - 3 is a linear function that follow y = mx+b. M is the slope or rate. Here m = -7 so the fish descends 7 meters per second. B is the y-intercept or starting position. Here the starting position is -3 so the fish starts 3 feet below sea level.
Given h(x) = -x + 2, solve for x when h(x) = -3.
;-;
The value of x when h(x) =-3 is 5.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
h(x) = -x + 2
Now, we have to find the value of x when h(x)= -3
So, h(x)= -3
-x+ 2= -3
Now, Subtracting 2 from both side
-x+ 2 -2= -3 -2
-x = -5
x= 5
Hence, the value of x is 5.

A. 600-60°-60°
O B. 70°-50-70°

Jason invests money in an account paying simple interest. He invests $160 and no money is added or removed from the investment. After one year, he has $164.80. What is the simple percent interest per year?
Answer:
The answer is 3%
Step-by-step explanation:
1.) $160 divided by $164.80 = 1.03
2.) 1.03 x 100 = 103
3.) 103 - 100 = 3
4.) 164.80 - 160 = 4.80
5.) 4.80 divided by 160 = 0.03
6.) 0.03 x 100 = 3%
