Find the possible value or values of n in the quadratic equation 2n2 – 7n + 6 = 0.

Answers

Answer 1

Answer: 2(n+7)(n-1)=0
because 7(-1) = -7 thats how you would get 7n and 7 - 1= 6 thats how you would get +6 and to be more specific it would be
n+7=0 n-1=0
n=-7 n= 1

The area of the closet floor is 18 feet. If Saroya buys 32 tiles will she have enough to cover the floor?

Answers

No shel will not have enough tile. If you don't know the dimensions of the actual tile how will you solve. If you have a closet 18 square feet it could be 9 ' x 2 ' = 18 square feet. If the tiles were 12" x 6" you would need 36 tiles. If the closet was 6' x 3' = 18 square feet you could have the tiles 12" x 6" = 36 tiles. So you need to know the dimensions of the tile.

Nth term question help please

Answers

Answer:

$\displaystyle{a.) \ \ a_n = -2n+14}\n\n\displaystyle{b.) \ \ a_n = -5n+30}$

Step-by-step explanation:

Part A

The common difference is -2 as the sequence decreases down to 2 each. Thus, the sequence is an arithmetic sequence. To find the nth term of an arithmetic sequence, we can follow the formula:

$\displaystyle{a_n = a_1+\left(n-1\right)d}$

Where $a_n$ is the nth term, $a_1$ is the first term, and $d$ is the common difference which we know that it is -2. By substitution of values we know, we will have:

$\displaystyle{a_n = 12+\left(n-1\right)\left(-2\right)}\n\n\displaystyle{a_n = 12-2n+2}\n\n\displaystyle{a_n = -2n+14}$

Hence, the nth term of the sequence is $\displaystyle{\bold{a_n = -2n+14}}$

Part B

The common difference is -5 as the sequence decreases by 5 each. This also makes the sequence an arithmetic sequence. Thus, we can apply the same formula as we did previously. By substitution of known values, we will have:

$\displaystyle{a_n = 25+\left(n-1\right)\left(-5\right)}\n\n\displaystyle{a_n = 25-5n+5}\n\n\displaystyle{a_n = -5n+30}$

Hence, the nth term of the sequence is $\displaystyle{\bold{a_n = -5n+30}}$

Use the cubic model y=3x^3 to find the value of y when x=8

Answers

Answer:

Value of y is 1536.

Step-by-step explanation:

We have given an expression $y=3x^3$

We need to find the value of y when x=8

We will substitute the value of x as 8 in the given expression we get

$y=3(8)^3$

On simplification we get

$y=3(512)$

On further simplification we get:

$y=1536$

Hence, the required value that is the value of y is 1536

pemdas

exponent first

y=3(8³)
8³=512
y=3(512)
y=1536

the value is 1536

We know that range is the set of outputs that shown on the y-axis of the graph, so we must find the endpoints of the graph on the y-axis. When we look, we get the endpoints -6 and 10, so we know that this is the range, and so we represent this in an expression:

-6 < y < 10
