A polynomial of degree n with roots
can be represented as:
, where A is a constant (The same "a" that appears outside the parentheses in the field where you will type the polynomial). In this question, the number of roots is 4, because the degree of f(x) is 4. If a polynomial has only real coefficients, the complex roots appear in pairs of conjugates. So, since
is a zero,
is a zero too. Then, we have the 4 zeros. Hence,
will be in the form:
Answer:
The number of sandwiches sold is 73. This is because it is multiplied by the expression for the money received per sandwich.
The cost to make each sandwich is <em>S. </em>This is stated in the first sentence of the problem.
<em />
The profit is 0.2<em>S. </em>This is because they sell each sandwich for an additional 20% of the cost ( S )
<em />
The amount of money the band receives is (<em>S </em>+ 0.2<em>S </em>). This is because it is the price per sandwich.

Answer:
step by step
Step-by-step explanation:
90 degrees is complementary
The distance between two positions with longitudes A and B is given by ||A| - |B|| if the two positions are at the same side of the meridian (0 degrees longitude) and |A| + |B| if both positions are at different sides of the meridian.
Given that <span>Moscow is at 37.62 degrees longitude and Brasilia is at -47.87
degrees longitude, thus the two cities are at different sides of the meridian.
Therefore, the distance </span><span>(in degrees) between the longitude lines of Moscow and Brasilia</span> is |37.62| + |-47.87| = 37.62 + 47.87 = 85.49
M(slope)= -5/4 point-slope(y-y1=m(x-x1)) so it would be y-5= -5/4(x+4)
