Hello from MrBillDoesMath

Answer:

35 * 10^7, which is Choice C

Discussion:

(5 * 10^4) /( 7 * 10^ 3 ) =

(5*7) * ( 10^4 * 10^3) = ( as 5 * 7 = 35)

(35) * 10 ^ (4+3) =

(35) * 10^7

which is choice C

Thank you,

Mr. B

Step-by-step explanation:

so first convert it into an algebraic equation

4 - ⅛w = 16

⅛w = 16-4

⅛w = 12

w=12÷ $\frac{1}{8}$

w=12×8=96

check: 4 - ⅛(96)=4-12=-8

-8<16 (-8 less than 16)

Find the first four terms of the sequence given by the following. aₙ=43-3(n-1) n=1,2,3. . .

Serggg [28]

Given :-

The general term of a sequence is given by aₙ=43-3(n-1) .

To Find :-

The first four terms of the sequence.

Solution :-

The given expression is $/$

→ aₙ=43-3(n-1)

where n > 0

Finding the first term :

Substituting n = 1 , we have ,

→ T1 = 43 - 3(1-1)

→ T1 = 43 - 3*0

→ T1 = 43 - 0 = 43

Finding the second term :

Substituting n = 2 , we have,

→ T2 = 43 -3(2-1)

→ T2 = 43 -3*1

→ T2 = 43 -3 = 40

Finding the third term :

Substituting n = 3 , we have,

→ T3 = 43 -3(3-1)

→ T3 = 43 -3*2

→ T3 = 43 -6 = 37

Finding the fourth term :

→ T4 = 43 -3(4-1)

→ T4 = 43 -3*3

→ T4 = 43-9 = 34

Hence the first four terms of the sequence are 43 , 40 , 37 and 34 .

I hope this helps . Let me know if you need further clarification .
