An arithmetic sequence is represented in the following table. Enter the missing term of the sequence.
x y
1 221
2 217
3 213
4 209
82 ?
When you subtract the y values you find that each increase in x decreases y by 4.
X is going from 4 to 82 which is 78 units.
78 x 4 = 312
Subtract 312 from the last y value:
209 - 312 = -103
The answer is -103
Answer:
When x = 82, y = -103
Step-by-step explanation:
So an arithmetic sequence is a sequence whose terms differ by a constant value. To find the value of the [tex]n^{th}[/tex] term we need to form an equation for the sequence.
Equation to the sequenceFirst we need to find the difference between the values of the sequence. In this case the difference is -4:
217 - 221 = -4, 209 - 213 = -4
So the equation is:
[tex]n^{th}[/tex] term = -4n + c
Now we need to find the c, so we substitute the [tex]n^{th}[/tex] term and the term number and solve the equation:
221 = (-4 x 1) + c
221 = -4 + c
c = 225
So the final equation is:
[tex]n^{th}[/tex] term = -4n +225
Finding the 82nd termNow all we need to do is substitute into the equation and find the answer:
[tex]n^{th}[/tex] term = (-4 x 82) + 225
[tex]n^{th}[/tex] term = -328 +225
[tex]n^{th}[/tex] term = -103
Which of the following inequalities is correct?
The correct inequality among the given options is -a > -c. Thus, option A is correct.
To determine the correct inequality among the given options, we need to compare the values of the variables a, b, and c in the number line.
Given: a = -4, b = 1, and c = 7
Let's evaluate each option:
A. -a > -c:
Substituting the values, we have -(-4) > -(7), which simplifies to 4 > -7.
This is true.
B. -a < -b:
Substituting the values, we have -(-4) < -(1), which simplifies to 4 < -1.
This is false.
C. a > 0:
Substituting the value, we have -4 > 0. This is false since -4 is not greater than 0.
Based on the comparisons, the correct inequality is A. -a > -c.
Therefore, the correct answer is A. -a > -c.

Rewrite each expression as a product of two fractions, one of which is equal to 1
(a) 10^5/10^2 = 1000
(b) x^2/x^6 = 1/(x^4)
(c) x^4y/xy^8 = x^3/y^7
a) To rewrite the expression 10^5/10^2 as the product of two fractions, we can write it as (10^5)/(10^2) = (10 * 10 * 10 * 10 * 10) / (10 * 10).
Next, we can simplify this expression by canceling out the common factors in the numerator and denominator. Since both the numerator and denominator have 10 as a common factor, we can simplify further to get (10 * 10 * 10 * 10 * 10) / (10 * 10) = 10 * 10 * 10 = 1000.
Therefore, the equivalent and simpler expression for 10^5/10^2 is 1000.
(b) For the expression x^2/x^6, we can rewrite it as (x * x) / (x * x * x * x * x * x).
Next, we can simplify this expression by canceling out the common factors in the numerator and denominator. Since both the numerator and denominator have x as a common factor, we can simplify further to get (x * x) / (x * x * x * x * x * x) = 1 / (x * x * x * x).
Therefore, the equivalent and simpler expression for x^2/x^6 is 1/(x^4).
(c) To rewrite the expression x^4y/xy^8 as the product of two fractions, we can write it as (x * x * x * x * y) / (x * y * y * y * y * y * y * y).
Next, we can simplify this expression by canceling out the common factors in the numerator and denominator. Since both the numerator and denominator have x and y as common factors, we can simplify further to get (x * x * x * x * y) / (x * y * y * y * y * y * y * y) = (x^3) / (y^7).
Therefore, the equivalent and simpler expression for x^4y/xy^8 is x^3/y^7.

Find the value of x in the triangle shown below
a. √8
b. √32
c. 32
d. 8
Answer:
5.65685424949 or 5.66
Step-by-step explanation:
In a right-angled triangle, the longest side/leg is called the hypotenuse.
The formula to solve for the hypotenuse is:
hyp^2= side^2+side^2
If the hypotenuse of the triangle is already given then we have to solve for a side.
The formula to solve for the side is:
side^2= hyp^2-side^2
This formula to solve for the side is the opposite of solving for the hypotenuse which is the longest side/leg of the right-angled triangle.
In this question we have to solve for the side.
There are two sides in this triangle. Let's name those sides side a and side b. Side a is already given.
hyp= 9
side a = 7
side^2 = hyp^2-side^2
side b = 9^2 - 7^2
side b = 81 - 49
side b = 32
side b = √32
side b= 5.65685424949. to 2 decimal places -> 5.66

A cube has a volume of 1000 cubic feet. What is the length of an edge of the cube?
Answer:
The length of an edge of the cube = x = [tex]\sqrt[3]{1000}[/tex] = 10 feet
Step-by-step explanation:
i.) A cube has a volume of 1000 cubic feet.
ii) A cube has edges which are all the same length, let us say that the length of an edge of the cube = x feet.
iii) therefore the volume of the cube is = [tex]x^{3}[/tex] = 1000 cubic feet
iv) therefore the length of an edge of the cube = x = [tex]\sqrt[3]{1000}[/tex] = 10 feet
Final answer:
The length of an edge of a cube with a volume of 1000 cubic feet is 10 feet. If each smaller cube has linear dimensions one tenth those of the larger cube, then the volume of each smaller cube is 1 cubic foot.
Explanation:
The volume of a cube is calculated by raising the length of one of its edges to the power of three (cubing it). Since we know the volume of the cube is 1000 cubic feet, we can determine the length of an edge by finding the cube root of the volume. The cube root of 1000 cubic feet is 10 feet, so the length of an edge of the cube is 10 feet.
To find the volume of the smaller cubes mentioned, we note that if their dimensions are one tenth of the larger cube, then each side of a smaller cube will be 10 feet divided by 10, which is 1 foot. The volume of each small cube is then 1 foot cubed, which is 1 cubic foot.
For a visual reference, imagine a larger cube divided evenly into smaller cubes, where the length of each side of the big cube is ten times that of the smaller ones. The result is that each smaller cube's volume is the original volume divided by the cube of 10 (since there are 10 layers of small cubes along each dimension of the big cube).

gary kicks a field goal with an inital veritcal velocity of 38m/s how long will it take the football to hit the ground
The ball reaches the ground after 7.76 s
Step-by-step explanation:
The motion of the ball along the vertical direction is a free fall motion, which is affected by the force of gravity only; therefore it is a uniformly accelerated motion (=constant acceleration), so we can use the following suvat equation:
[tex]s=ut-\frac{1}{2}gt^2[/tex]
where
s is the displacement
u is the initial vertical velocity
[tex]g=9.8 m/s^2[/tex] is the acceleration due to gravity
t is the time
In this problem,
u = 38 m/s
Also, we want to find the time t at which the ball hits the ground again: so, when the displacement becomes zero again,
s = 0
Therefore the equation becomes:
[tex]0=38t-\frac{1}{2}9.8t^2\\0=38t-4.9t^2[/tex]
And solving for t,
[tex]t(38-4.9t)=0[/tex]
we have two solutions:
t = 0 (instant at which the ball is kicked)
[tex]38-4.9t=0\\t=\frac{38}{4.9}=7.76 s[/tex]
which is the solution to the problem.

Point A' is 4 units left and 2 units down from point A, so the translation is T<-4, -2>.
Segment C"D" is on the -x axis, 90° counterclockwise from segment C'D' on the +y axis. Since rotation angles are measured the same way other angles are measured (positive is CCW), the rotation is +90° about the origin.

11. Jessica invested $18820 to buy a new car for her business. How many years would it take for
this car to depreciate to $4520? Assume declining-balance method of depreciation with a rate
of depreciation of 30%. (Answer to the nearest year.)
Answer :after four years the price of car depreciate
Final answer:
It will take approximately 4 years for the car to depreciate to $4520 using the declining-balance method of depreciation with a depreciation rate of 30%.
Explanation:
To calculate the number of years it would take for the car to depreciate to $4520, we can use the declining-balance method of depreciation. The declining-balance method is based on a fixed percentage of the remaining value of the asset. In this case, the rate of depreciation is 30%, so the car's value will decrease by 30% each year.
Let's start by finding the value of the car after one year. We can use the formula:
Value after one year = Initial value - (Rate of depreciation * Initial value)
Plugging in the values, we get:
Value after one year = $18820 - (0.3 * $18820) = $18820 - $5646 = $13174
Now, let's find the value after the second year:
Value after two years = $13174 - (0.3 * $13174) = $13174 - $3952.2 = $9221.8
We continue this process until we reach a value of $4520. By the time the car's value reaches $4520, it will have taken approximately 4 years.

A scatter plot of data comparing the humber of years since Holbrook High School introduced a math club and the number of student participating contains the ordered pairs (3,19) and (8, 42). What is the slope-intercept form of an equation for the line of fit containg those two pairs?
A) y = 0.22x - 1.13
B) y = 4.6x + 5.2
C) y = 5.2x + 4.6
D) y = 3x + 1
Answer:
Option B, y = 4.6x + 5.2
Step-by-step explanation:
Slope-intercept form: y = mx + b
Step 1: Use those two points to get slope
m = [tex]\frac{y2 - y1}{x2 - x1}[/tex]
m = [tex]\frac{42 - 19}{8 -3}[/tex]
m = [tex]\frac{23}{5}[/tex]
m = 4.6
Step 2: Find the y - intercept
Use point slope formula: (y - y1) = m(x - x1)
(y - 19) = 4.6(x - 3)
y - 19 + 19 = 4.6x - 13.8 + 19
y = 4.6x + 5.2
Answer: Option B, y = 4.6x + 5.2
