The equation for the nth term of the arithmetic sequence is -6n + 14 and the found 50 is -286.
What is an arithmetic sequence?An arithmetic sequence is a series of numbers that are ordered and share a common difference between each succeeding term. In the arithmetic sequence 3, 9, 15, 21, 27, for example, the common difference is 6.
Arithmetic is the branch of mathematics that studies numbers by performing various operations on them. A sequence is a numerically ordered list. The three dots indicate that the pattern should be continued. The difference is six.
a + d(n - 1)
a = 8 (first term)
d = -6 (common difference)
8 - 6(n - 1)
= 8 - 6n + 6
= -6n + 14
Find a 50:
-6(50) + 14
= -300 + 14
= -286
Therefore, the equation for the nth term of the arithmetic sequence is -6n + 14.

can i get the answer for number 16
Answer:
25
Step-by-step explanation:
For each problem, the two numbers on the left are perfect squares. The number in the upper right is the square of the difference between the two numbers on the left. The number on the bottom right is equal to the number on the upper right plus the number on the upper left.
For problem 16, we know that the square of the difference between 36 and the missing number is 121. The square root of 121 is 11, so the missing number is 36 - 11 = 25 which fits the pattern because it is also a perfect square.
(Also if you look at problem 15, it basically gives you the answer to problem 16.)
Answer:

When Gopal gives Rs 10 from his money to Laxmi her money becomes double thanthat of the remaining money of Gopal. When Laxmi gives Rs 10 to Gopal his moneyis still Rs 10 less than the remaining money of Laxmi. Find their original sum ofmoney.
Answer:
money with Gopal rs. 60
money with laxmi Rs. 90
Total money with them = Rs. 150
Step-by-step explanation:
Let money with gopal be x
let money with laxmi be y
Given
Gopal gives Rs 10 from his money to Laxmi her money becomes double thanthat of the remaining money of Gopal
Money left with gopal after giving Rs 10 = x-10
money with Laxmi after getting rs 10 = y+10
according to given condition
money with laxmi = 2*money left with Gopal
y+10 = 2(x-10)
___________________________________________________
Laxmi gives Rs 10 to Gopal his moneyis still Rs 10 less than the remaining money of Laxmi.
Money left with Laxmi after giving Rs 10 = y-10
money with Gopal after getting rs 10 = x+10
according to given condition
money with laxmi -10 =money with Gopal
y-10-10 =x+10
y-20 = x+10
=> y = x+10+20
y = x+30
substituting y = x+30 in y+10 = 2(x-10)
x+30 +10 = 2(x-10)
x+40 = 2x-20
=>40+20 = 2x-x
=> x = 60
y = x+30 = 60+30 = 90
Thus,
money with Gopal rs. 60
money with laxmi Rs. 90
Total money with them = 60+90 = rs. 150

Sarah and Jim leave a train station at the same time traveling 20mi/h faster that Jim’s train. After 3 hours the were 270 miles apart how fast was each train going
Answer:
speed of Jim's train = 35 mi/h
speed of Sarah's train = 35 +20 mi/h = 55 mi/hour
Step-by-step explanation:
Let the speed of Jim's train be x mi/h
Given, Sarah and Jim leave a train station at the same time traveling 20mi/h faster that Jim’s train.
speed of Sarah's train = x + 20 mi/h
we know distance = speed * time
time = 3 hours
distance traveled by Sarah's train = 3*(x+20) = 3x+60 miles
distance traveled by Jim's train = 3*x = 3x miles
It is not given that if trains are moving in same or opposite direction.
__________________________________
if they are travelling in same direction
Then, then distance between them = total distance traveled by
faster train - total distance traveled by
slower train = 3x +60 -3x = 60 miles
which is wrong as the two trains are 270 miles apart
hence, they are travelling in opposite direction
In this case
distance between them = total distance traveled by
faster train + total distance traveled by
slower train = 3x +60 + 3x = 6x + 60 miles
given that the trains are 270 miles apart
6x + 60 miles = 270 miles
6x = 270 - 60 = 210
x = 210/6 = 35
Thus, speed of Jim's train = 35 mi/h
speed of Sarah's train = 35 +20 mi/h = 55 mi/hour

The entire graph of the function f is shown in the figure below. Write the domain and range of f using interval notation?
========================================================
Explanation:
The domain is the set of allowed x values. In terms of a graph, we look at the left most point to see that x = -5 is the smallest x value possible. However, there's an open hole at this endpoint, so -5 itself is actually not part of the domain. So x must be larger than -5. At the same time, x can be as large as x = 3. Look at the very right tip of the graph to find this x value.
So x spans from -5 to 3, excluding -5 but including 3. We would write [tex]-5 < x \le 3[/tex] which converts to the interval notation (-5, 3]. Note the mix of curved parenthesis and square bracket. The curved parenthesis means to exclude the endpoint, while the square bracket means include the endpoint.
-----------
The range is the set of possible y outputs. Find out the lowest point of the graph. That is when y = -4 and this value is included due to the filled in circle at the endpoint. But we do not include the largest y value y = 5 as there's an open hole at this endpoint.
So the range is the set of y values such that [tex]-4 \le y < 5[/tex] which in interval notation would be written as [-4, 5)
-----------
So in short, you're looking for the min and max of x and y to get the domain and range respectively. Be sure to exclude any values where there are open holes as those do not count as part of the graph.
For a given function f(x), we define the domain as the set of the possible inputs for that function.
Here we will see that the domain is (-5, 3]
So, to find the domain by looking at a graph, we need to see the smallest x-value and the largest x-value.
In the graph, at the left, we can see that we have a white dot at x = -5
This means that the point itself does not belong to the domain, so here we need to use an open interval symbol, which is (
Then at the moment, we have:
domain = (-5
Now if we look at the right side, we can see that we have a black dot at x = 3.
This means that the value x = 3 belongs to the domain, so here we need to use the close symbol ].
Then the domain will be:
(-5, 3]

Kim was waling down a path for 4 minutes the elavation changed at the same rate altogether it dropped 8 feet what was the change in elavation each minute
Answer:
2 ft/min
Step-by-step explanation:
Given that :
Kim was waling down a path for 4 minutes the elavation changed at the same rate altogether it dropped 8 feet what was the change in elavation each minute?
Time taken it wall down the path = 4 minutes
Rate of change of elevation is the same

Distance dropped / time taken to drop that distance
8 Feets / 4 minutes
2 Feets / minute
Change in elevation = 2 Feets per minute
2% Of A=3% OF B = 4% of c then A:B:C: is?
Answer:
6:4:3.....................
The ratio between A, B, and C is 6:4:3.
To determine the ratio between A, B, and C based on the given information, we can set up the following equations:
2% of A = 3% of B
4% of C = 3% of B
Let's solve for the variables and find the ratio:
First equation: 2% of A = 3% of B
0.02A = 0.03B
A/B = 0.03/0.02
A/B = 1.5
Second equation: 4% of C = 3% of B
0.04C = 0.03B
C/B = 0.03/0.04
C/B = 0.75
Now, let's express the ratio A:B:C based on the ratios we found:
A:B = 1.5:1
B:C = 1:0.75
To obtain a common ratio, we can multiply both ratios by 4:
A:B = 6:4
B:C = 4:3
Combining these ratios, we have:
A:B:C = 6:4:3
Therefore, the ratio between A, B, and C is 6:4:3.

Find the measure of WV¯¯¯¯¯¯¯¯¯. A. 8 B. 6 C. 7 D. 4
Answer:
[tex]\Huge \boxed{\mathrm{B. \ 6}}[/tex]
Step-by-step explanation:
We can apply the Intersecting Secant-Tangent Theorem.
TV is the secant.
VW is the tangent.
VW² = VT × VU
(x+6)² = (5+x+4) × (x+4)
Combine the terms in bracket.
(x+6)² = (x+9)(x+4)
Expand brackets on both sides of the equation.
x²+12x+36=x²+13x+36
Subtract x² from both sides.
12x+36=13x+36
Subtract 12x from both sides.
36=x+36
Subtract 36 from both sides.
0=x
WV = x+6
x=0
WV = 0+6 = 6
The measure of the tangent WV is 6.

The perimeter of a rectangle is 24 m. The length is 30 m less than five times the width. Find the dimensions of the rectangle. List answer as follows: width, length.
Answer:
width = 7 mlength = 5 mStep-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
Perimeter = 24m
The statement
The length is 30 m less than five times the width is written as
l = 5w - 30
Substitute the expression into the above formula and solve for the width
That's
24 = 2( 5w - 30) + 2w
24 = 10w - 60 + 2w
84 = 12w
Divide both sides by 12
w = 7
Substitute this value into l = 5w - 30
That's
l = 5(7) - 30
l = 35 - 30
l = 5
Therefore the dimensions are
width = 7 m
length = 5 m

The coordinates of point T are (0,5). The midpoint of ST is (2,-2). Find the coordinates of point S.
Answer:
(4, -9)
Step-by-step explanation:
Find the distances between the x and y coordinates of point T and the midpoint:
2 - 0 = 2 (distance of x values)
-2 - 5 = -7 (distance of y values)
Add these two values to the coordinates of the midpoint:
2 + 2 = 4 (x value of point S)
-2 - 7 = -9 (y value of point S)
So, point S is at (4, -9)

y = 60 x
y = 60 x + 480
y = 4 x + 240
y = 270 x
Answer: Y=60x
Step-by-step explanation:
find the slope (Y2-Y1)/(X2-X1)
(240-150)/4-2.5)
90/1.5 =60
It's multiple choice so it can only be a or b. If you do 60 x 2.5 you get 150 so there's no way you will add 480 so you are done it's A. If it's not a multiple choice question then you would do the who y=mx+b and plug in x, y and m and then find the b which in this case would be 0.
Answer:
(2.5,150)(4,240)
slope = (240 - 150) / (4 - 2.5) = 90 / 1.5 = 60
y = mx + b
slope(m) = 60
(4,240)...x = 4 and y = 240
now we sub and find b, the y int
240 = 60(4) + b
240 = 240 + b
240 - 240 = b
0 = b
so ur equation is : y = 60x + 0 which is written as : y = 60x <==
An elevator in an office building made the following moves: Up 7 floors, down 14 floors, up 6 floors, down 2 floors, up 9 floors, down 5 floors. If the elevator stopped on the 54th floor, what floor did it start on?
Answer:
It started on the 55th floor.
Step-by-step explanation:
We can work backwards from the 54th floor. Since we are working backwards, if the elevator goes up, we will subtract and if it goes down, we will add. Starting with 54, we get 54 + 5 = 59, then 59 - 9 = 50, then 50 + 2 = 52, then 52 - 6 = 48, then 48 + 14 = 62, then 62 - 7 = 55.
