What is the quotient in the polynomial form?
Oxana [17]

First step of a synthetic divison is that we need to carry down the leading coefficient. Here the leading coefficient is 2. So, carry down 2 at the bottom.

Next step is to multiply the divisor -3 with this carry down number 2. So, we have got 3*(-2)= -6 which will place atthe bottom of the next coefficient 4.

Next step is to add this column.

Now repeat the same method again till the last colum.

At the end we have got 0 after the addition. Which means the remainder is 0.

So, the quotient is 2x^2-2x+2.

if a triangular sail has a vertical height of 83 ft and horizantal length of 40 ft, what is the area of the sail?
Irina18 [472]

Answer:

A = 1660 ft^{2}

Step-by-step explanation:

Area of the sail or a triangle is base times height

A = \frac{1}{2}(b x h)

Base is 40 ft (horizontal length)

Height is 83 ft (vertical height)

A = \frac{1}{2}(b x h)

A = \frac{1}{2}(40 x 83) =  \frac{1}{2}(3320) = 1660 ft^{2}
