4th term of an arithmetic sequence is 23 and its 11th term is 65, what is its common difference

Rudik [331]

Answer:

d = 6

Step-by-step explanation:

The nth term of an arithmetic sequence is

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₄ = 23 and a₁₁ = 65 , then

a₁ + 3d = 23 → (1)

a₁ + 10d = 65 → (2)

Subtract (1) from (2) term by term to eliminate a₁

10d - 3d = 65 - 23

7d = 42 ( divide both sides by 7 )

d = 6

AFTER HALLOWEEN, PUMPKINS WERE 25% OFF. AMY BOUGHT 2 BIG PUMPKINS THAT WERE ORIGINALLY $7 EACH. HOW MUCH DID SHE SPEND (BEFORE T

Lady bird [3.3K]

Answer:

$ 10.50

Step-by-step explanation:

we can use a proportion to answer this question

25 : 100 = x : 7

x = (25 * 7)/100 = $1.75 (value of the discount)

Final price = 7 - 1.75 = $5.25

she bought two = 5.25 x 2 = $10.50

Two pools are being filled with water. To start, the first pool had 1850 liters of water and the second pool had 1334 liters of

prohojiy [21]

Answer:

a)Total amount of water in pool 1 after x minutes = 1850+27x

Total amount of water in pool 2 after x minutes = 1334+39x

b) an equation to show when the two pools would have the same amount of water is 1850+27x= 1334+39x

Step-by-step explanation:

First Pool :

Initial amount of water in Pool = 1850 liters

Water is being added to the first pool at a rate of 27 liters per minute.

Amount of water added after x minutes = 27x

So, Total amount of water after x minutes = 1850+27x

Second Pool:

Initial amount of water in Pool = 1334 liters

Water is being added to the first pool at a rate of 39 liters per minute.

Amount of water added after x minutes = 39x

So, Total amount of water after x minutes = 1334+39x

Now to find an equation to show when the two pools would have the same amount of water.

1850+27x= 1334+39x

1850-1334=39x-27x

516=12x

$\frac{516}{12}=x$

43 =x

Hence

a)Total amount of water in pool 1 after x minutes = 1850+27x

Total amount of water in pool 2 after x minutes = 1334+39x

b) an equation to show when the two pools would have the same amount of water is 1850+27x= 1334+39x

Write a function in any form that would match the graph shown below

Basile [38]

Answer: The most common graphs name the input value

and the output value

, and we say

is a function of

, or

(

)

when the function is named

. The graph of the function is the set of all points

(

)

in the plane that satisfies the equation

(

)

. If the function is defined for only a few input values, then the graph of the function is only a few points, where the x-coordinate of each point is an input value and the y-coordinate of each point is the corresponding output value. For example, the black dots on the graph in the graph below tell us that

(

)

and

(

)

. However, the set of all points

(

)

satisfying

(

)

is a curve. The curve shown includes

(

)

and

(

)

because the curve passes through those points.

Graph of a polynomial.

The vertical line test can be used to determine whether a graph represents a function. A vertical line includes all points with a particular

value. The

value of a point where a vertical line intersects a graph represents an output for that input

value. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that

value has more than one output. A function has only one output value for each input value.

Three graphs visually showing what is and is not a function.

HOW TO: GIVEN A GRAPH, USE THE VERTICAL LINE TEST TO DETERMINE IF THE GRAPH REPRESENTS A FUNCTION.

Inspect the graph to see if any vertical line drawn would intersect the curve more than once.

If there is any such line, the graph does not represent a function.

If no vertical line can intersect the curve more than once, the graph does represent a function.
