The nth term of a sequence is n(n-8)÷√n+3 find the 1st and 6th terms

kotykmax [81]

Answer:

-4 and -2✓6+3

Step-by-step explanation:

use pemdas

1(1-8)÷✓1 + 3

-7÷1+3

-4

6(6-8)÷✓6+3

-12÷✓6+3

multiply fraction by ✓6 on bottom and top to get rid of square root on bottom

-12✓6÷6+3

divide -12 by 6 and put radical next to it

-2✓6+3

A cup is 6.4 cm tall, not including a 0.6 cm lip. Cups are stacked inside one another. You may want to draw a diagram to help yo

Ivenika [448]

H(c)=6.4+0.6c
6.4 is the constant

when the height of the cups is 18.4 the function is:
18.4=6.4+0.6c
then you subtract 6.4 from both side to get:
18.4 - 6.4=6.4 + 0.6c - 6.4
12=0.6c
c= 12/.6
c=20

Simplify completely quantity 12 x plus 36 over quantity x squared minus 4 x minus 21 and find the restrictions on the variable.

Alex777 [14]

Option B

12 over quantity x minus 7, x ≠ 7, x ≠ −3

Solution:

Given that we have to simplify quantity 12 x plus 36 over quantity x squared minus 4 x minus 21

So we have to simplify,

$\frac{12x + 36}{ {x}^{2} - 4x - 21 }$

We have to find the restrictions on the variable

The above given Rational function is defined, for

${x}^{2} - 4x - 21\ne0\\\\(x+3)(x-7)\ne0\\\\x\ne -3,x\ne7$

In order to simplify the above expression, we need to factor both the numerator and the denominator

$\rightarrow \frac{12x + 36}{ {x}^{2} - 4x - 21 } = \frac{12(x + 3)}{ {x}^{2} - 4x - 21}$

For the denominator, we need to split the middle term of the quadratic to get factored form,

$\rightarrow \frac{12x + 36}{ {x}^{2} - 4x - 21 } = \frac{12(x + 3)}{ {x}^{2} - 7x + 3x- 21}$

$\frac{12x + 36}{ {x}^{2} - 4x - 21 } = \frac{12(x + 3)}{ x(x - 7) + 3(x- 7)}$

Fcatoring the denominator part,

$\frac{12x + 36}{ {x}^{2} - 4x - 21 } = \frac{12(x + 3)}{ (x + 3)(x - 7)}$

Cancel out common factors to get,

$\frac{12x + 36}{ {x}^{2} - 4x - 21 } = \frac{12}{x - 7} \\\\where\\\\x\ne -3,x\ne7$

Thus option B is correct. 12 over quantity x minus 7, x ≠ 7, x ≠ −3
