Roberto's toy car travels at 30 centimeters per second (cm/sec) at high speed and 20 cm/sec at low speed. if the car travels for 20 seconds at high speed and then 30 seconds at low speed, what distance would the car have traveled

1200 centimeters in total, 600 seperate

Step-by-step explanation:

30 cm/second at high speed for 20 seconds = 30 * 20 = 600.

20 cm/second at low speed for 30 seconds = 20 * 30 = 600.

600 + 600 = 600 * 2 = 1200 cm in total

b. x + 1

step-by-step explanation:

(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.
