Step-by-step explanation:

Under a counterclockwise rotation about the origin of 90°

a point (x, y ) → (- y, x ), thus

Yanka [14]

Answer:

<u>$4800</u>

Step-by-step explanation:

The expected net income is the probability when rains multiplied by net income (profit) summed with the probability of not raining with that days net income multiplied.

First, Chance of rain = 12% = 12/100 = 0.12

Profit/Loss = Income - Cost

Income is 5000

Cost = 9000

So,

Loss = 5000 - 9000 = 4000

Or, Net Income (profit) = - 4000

Now, Change of not raining = 100 - 12 = 88% = 88/100 = 0.88

Profit = Income - Cost

Income = 15,000

Cost = 9000

Net Income (profit) = 15000 - 9000 = 6000

So, we can write the expected net income as:

<u>Expected NI </u>= (0.12)(-4000) + (0.88)(6000) = <u>$4800</u>

In a quadratic function, f(x)= ax^2+bx+c the leading coefficient is a, i.e. the coefficient of x^2, and the constant term is c, i.e. the coefficient without any power of x.

So, if you want leading coefficient 2 and constant term -3, your function needs to be like

f(x)=2x^2+bx-3

for any value of b. Among your options:

  • The first is not a quadratic (it starts with x^3)
  • The second has leading term -3 and constant term 2
  • The third is not a quadratic (same as the first)
  • The last is correct.
