Answer:

x = ± √−1

No real solutions

Step-by-step explanation:

x^2 + 10 = 9

Subtract 10 from both sides

x^2 + 10 = 9

      - 10  - 10

x^2 = − 1

Take the square root

x = ± √−1

1. Work out the speed of a car travelling:
Norma-Jean [14]

Answer:

10m/s,15m/s,20m/s,5m/s

Step-by-step explanation:

Speed = distance / time

a) distance = 100m , time = 10s

Speed = distance / time

Speed = 100m/10s

Speed = 10m/s

b) distance = 300m , time = 20s

Speed = distance / time

Speed = 300m/20s

Speed = 15m/s

c) distance = 700m , time = 35s

Speed = distance / time

Speed = 700m/35s

Speed = 20m/s

d) distance = 1000m , time = 200s

Speed = distance / time

Speed = 1000m/200s

Speed = 5m/s

The price of a computer component is decreasing at a rate of 15% per year.
Alex_Xolod [135]

Answer:

  • exponential
  • $30.71

Step-by-step explanation:

Usually, this wording means the decrease is proportional to the current price, characteristic of an exponential function.

__

The decay factor is 1-(decay rate), so is 1-0.15 = 0.85. After 3 years, the value has been multiplied by this factor 3 times:

  $50×0.85³ ≈ $30.71 . . . . cost in 3 years

_____

<em>Comment on percent per year</em>

Less often, the indicated decrease is intended to be <em>that percentage of the original price</em>. The result is that the price decreases by a constant amount each year, a linear decrease. This condition most often arises in conjunction with figuring depreciation in value for tax or accounting purposes.

The upshot is that you always need to be careful to understand what the base of a percentage is intended to be.
