Find the nth term of this quadratic sequence 3 8 15 24
Answer:
35
Step-by-step explanation:
A quadratic sequence is a form. of mathematical progression of numbers in which the subsequent differences between each consecutive term differ by the exact amount. This is known as the common second difference.
Hence in this case,
we have
S= 3+8+15+24+…..+Tn - 1.
S=. 3+8+15+……………..Tn-1 + Tn
Deducting 2nd series from the first
We have 0=3+5+7+…….Tn
Hence, we have Tn= n (n+2)
= 24 (9+2)
= 24 + 11
= 35
x = - 5
x ^ 2 + y ^ 2 = 25
show work also
Step-by-step explanation:
Since x is equal to -5, you would need to substitute that value for x in the equation x^2 + y^2 = 25. So....
-5^2 + y^2 = 25
(-5)*(-5) + y^2 = 25
25 + y^2 = 25
y^2 +25 - 25 = 25 - 25
y^2 = 0
y = 0
(x, y) = (-5, 0)
To check the answer....
x^2 + y^2 = 25
-5^2 + 0^2 = 25
25 + 0 = 25
25 = 25
The answer should be correct, if not i am extremely sorry

Carlos visita a sus abuelos cada 12 dias y su hermana sofia,cada8 dias.La ultima vez que conincidieron en la visita fue el dia 3 de enero ¿cuando volveran a coincidir? ¿cuantas veces habran visitado a sus abuelos cada uno entre los dos periodos que han coincidido?
Responder:
27 de enero
Horas de visita al abuelo antes de que coincida el horario = 1 vez
Horas de visita a Sofía antes de que coincida el horario = 2 veces
Explicación paso a paso:
Para obtener la hora en la que coincidirá su visita, obtenemos la L. C. M de 12 y 8
Abuelos (cada 12 días)
12:12, 24, 36, 48, 60, ...
Sofia (cada 8 días)
8: 8, 16, 24, 32, 40, ....
El mínimo común múltiplo de 12 y 8 es 24.
De ahí que su encuentro vuelva a coincidir a los 24 días.
3 de enero + 24 días = 27 de enero
Horas de visita al abuelo antes de que coincida el horario = 1 vez
Horas de visita a Sofía antes de que coincida el horario = 2 veces

Parallelograms s and t are each labeled with a base and a corresponding height
Answer:
Parallelogram S:
b = 7 and h = 6
Parallelogram T:
b = 3 and h = 6
Step-by-step explanation:
The given information is incomplete and is not enough to answer the question. (See attachment for complete question)
Required
Determine the values of b and h for both parallelogram
The question will be answered by observing the features of each parallelogram and recording the required values
For parallelogram S.
The vertical arrow at the left-hand side represents b and the arrow highlights 7 grid boxes.
Hence:
[tex]b = 7[/tex]
The horizontal dotted lines represents h and this line highlights 6 grid boxes.
Hence:
[tex]h = 6[/tex]
For parallelogram T.
The horizontal arrow represents b and the arrow highlights 3 grid boxes.
Hence:
[tex]b = 3[/tex]
The vertical dotted lines represents h and this line highlights 6 grid boxes.
Hence:
[tex]h = 6[/tex]

You are calculating how many seats there are at Camp Nou in Barcelona, Spain. You count that there are 3,300 rows. Each row has 30 seats. How many seats are there in the whole stadium?
Answer:
This should be a simple math problem if I didn`t miss understand anything the answer should be 99000
Step-by-step explanation:
99000 I think
Answer:
99,000
Step-by-step explanation:
If there are 30 seats in each row, you must multiply 30 by the number of rows there is. There are 3300 rows. Therefore, the answer to 3300 x 30 would be 99000.

Diego collected x kg of recycling. Lin collected 2/5 more than that. [ Select ] Lin biked x km. Diego biked 3/10 less than that. y = 10/3x Diego read for x minutes. Lin read 4/7 of that. y = 7/4x
I assume you want to mathematically represent the above
Answer and explanation:
If Diego collected x kg of recycling and Lin collected 2/5 more than what Diego collected, then it would be represented mathematically thus:
Diego = x
Lin = x +2/5 of x= x+2/5x
if Lin biked x km and Diego biked 3/10km less than Lin, then we would represent this thus:
Lin=x
Diego= x-3/10 of x= x-3/10x
If Diego reads for x minutes and Lin reads 4/7 of what Diego read, then mathematically we represent this thus:
Diego=x
Lin =4/7 of x = 4/7x

Solve. Chanasia has 6.25 gallons of paint. She wants to use 2/5 of the paint to paint her living room. How many gallons of paint will Chanasia use?
Answer: 2.5 gallons
Step-by-step explanation:
Given that:
Gallons of paint had = 6.25 gallons
Amount needed to paint room = 2/5 of the paint
Gallons of paint needed :
2/5 of 6.25
(2 * 6.25) / 5 gallons
= 12.5 / 5
= 2.5 gallons
someone help ASAP !! algebra II
Answer:
C
Step-by-step explanation:
Given y = f(x) then y = f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
Thus (x - 5)² is a shift to the right of 5 units
Given y = f(x) then y = f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Thus
y = (x - 5)² + 6
is the graph of y = x² translated 6 units up and 5 units to the right → C
Please provide an explanation, thank you!

What are different values in a linear equation of a straight line?
The equation y = mx + c is the general equation of any straight line where m is the gradient of the line (how steep the line is) and c is the y-intercept (the point in which the line crosses the y-axis).
y = mx + c is a linear equation and the variables x and y relate to coordinates on the line.
When we input a value for x into the equation y = mx + c, we get a result for y.
This means that x is an independent variable, and y is a dependent variable as it is determined by the value of x.

A 32-ounce jar of a barbecue sauce costs $8.00, while an 8-ounce jar of the same
sauce costs $4.00. How much less does Jennifer pay per ounce by purchasing
the jar that costs less per ounce?
Answer:
Jennifer would save $0.25 per ounce.
Step-by-step explanation:
With the 32-ounce jar, the price per ounce is $0.25 per ounce. With the 8-ounce jar, the price is $0.50 per ounce. Jennifer would do better to buy the 32-ounce jar, as she would save $0.25 per ounce with that choice.

Step-by-step explanation:
20x² = y - 24
y = 20x² + 24
For y to have the least possible value, x² have to be the least possible, which is 0.
Since -3 <= x <= 2 includes x = 0, this is allowed.
Hence least possible value of y
= 20(0)² + 24 = 24.
Answer:
24
Step-by-step explanation:
-3---> 20(-3)^2=y-24 ----> y=204
-2---> 20(-2)^2=y-24 ----> y=104
-1---> 20(-1)^2=y-24 ----> y=44
0---> 20(0)=y-24 ----> y=24
1---> 20(1)^2=y-24 ----> y=44

1. A term that is a known number without variables. is called?
2. A term that includes a variable. is called?
Answer:
Constants are the terms in the algebraic expression that contain only numbers. That is, they're the terms without variables. We call them constants because their value never changes, since there are no variables in the term that can change its value.
An algebraic expression is one or more algebraic terms in a phrase. It can include variables, constants, and operating symbols, such as plus and minus signs.

Step-by-step explanation:
150/2 = 75
72/8=9
Answer:
v is 9 degrees
Step-by-step explanation:
The 2 angles are supplementary angles
Therefore,
8v + 3 + 105 = 180 (supplementary angles add up to 180 degress/straight line)
8v = 180 - 105 - 3
8v = 75 - 3
8v = 72
v = 72/8
v = 9 degrees
