Ava solved the problem 7.4×1.2 with partial products. These are the first 3 steps.

7.0×1.0=7

7.0×0.2=1.4

0.4×1.0=0.4

Which is the final line of her partial product and the correct answer?

A.

0.4×2=0.8

; 9.6
B.

0.4×0.2=0.08

; 8.88
C.

0.4×0.02=0.08

; 8.88
D.

0.4×0.2=0.8
; 9.96

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
