Hi. Please i need help with this question. Find the operation used in determining each of the values in the diagram.
Workings Please.

3*3+1=10

4*4+5=21

Step-by-step explanation:

You square the number in the first box

3*3=9

4*4=16

And add the number in the second box with the result.

3*3=9+1=10

4*4=16+5=21

Hope this helps ;) ❤❤❤

Step-by-step explanation:

We must square the number on the left box, then add with the number in the right box to get the result in the boxes below.

3² + 1 = 9 + 1 = 10

4² + 5 = 16 + 5 = 21

110698.56 square miles

step-by-step explanation:

multiply 3.8 by 102

387.6

multiply 2.8 by 102

285.6

multiply those two to get

(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.
