Answer:
Step-by-step explanation:
The division problem given to us is .
To perform the synthetic division, we write out the coefficient of the polynomial. We set the linear factor to zero and solve for x, this becomes our divisor. That is .
We carry out the synthetic division as shown in the attachment.
The result of the synthetic division is 4 -27 167 -996
The first three terms are the coefficients of the quotient and the last term is the remainder.
Therefore the quotient is and the remainder is
.
The dividend, the quotient and the divisor are written as
The correct answer is A
Answer:
Radius of the Earth is 3978.8 Miles
Circumference of the Earth is 25000 Miles
Step-by-step explanation:
The angle of the sun shone at an angle of 7.2° to the zenith
This means that the angle of the sector of the circle is 7.2° (θ)
S = Length of the sector of the circle = 500 miles
r = radius of earth
Converting 7.2° to radians
∴ Radius of the Earth is 3978.8 Miles
∴ Circumference of the Earth is 25000 Miles
