Identify the 27th term of an arithmetic sequence where a1 = 38 and a17 = -74.

makkiz [27]

Arithmetic sequence:
an=a1+(n-1)d
$a_{17}= a_{1}+16d

-74=38 + 16d

16d=-74-38

16d=-112$
d=-112/16=-7
$a_{27}=a_{1} + 26d=38+26*(-7)=38-182=-144$
Answer: D)-144

(z-24) divided by 8+2

hjlf

Answer:

z=-24

Step-by-step explanation:

(z-24)/8+2

(z-24)/10

((z-24)/10)10 Multiply both sides by 10

10(z-24) Distribute

10z-240 Divide both sides by 10

z=-24

Answer:

are you sure its a polynomial

Step-by-step explanation:

A polynomial is a combination of terms separated by

What is the value of the expression if m = –5 and n = 3? Negative StartFraction 24 Over 25 EndFraction Negative StartFraction 4

KatRina [158]

You can use the fact that a number raised to negative powers can be written as 1 divided by that number raised to positive number.

The value of the given expression when m = -5 and n= 3 is $-\dfrac{2}{5}$

<h3>How can we rewrite a number raised to negative power?</h3>

Suppose we've got $a^{-b}$ . then it can be rewritten as

$a^{-b} = \dfrac{1}{a^b}$

It is because $a^0 = 1$ for any a except 0, and that $\dfrac{a^0}{a^b} = a^{0-b} = a^{-b}$

If base are same and there is multiplication, then there will be addition in power.

Also, know the fact that if base are same and there is division, there will be subtraction in power(subtracting since that denominator when goes up, its power gets negated(gets negative sign to the existing power)

Thus,

$a^b \timesa ^c = a^{b+c}\\\\\dfrac{a^b}{a^c} = a^{b-c}$

<h3>Using above method to simplify the given expression before evaluating</h3>

The given expression is $\dfrac{2m^{-1}n^5}{3m^0n^4} = \dfrac{2n^5}{3m^0m^1n^4} = \dfrac{2n^5}{3mn^4} = \dfrac{2n^{5-4}}{3m} = \dfrac{2n^1}{3m} = \dfrac{2n}{3m}$

Putting m = -5 and n=3, we get:

$\dfrac{2\times 3}{3 \times -5} = -\dfrac{2}{5}$

Thus,

The value of the given expression when m = -5 and n= 3 is $-\dfrac{2}{5}$
