\frac{7}{100}  =  \frac{21}{x}  \\ x =  \frac{21 \times 100}{7}  =  \frac{2100}{7}  = 300
there are 300 students in the high school.

State the number of complex zeros, the possible number of real and imaginary zeros, and the possible rational zeros for each fun
ArbitrLikvidat [17]
Since the degree of this polynomial is 5, there will be 5 possible zeros. To find the possible rational 0s, use the rational root theorem (p/q). P is the last, non x value, which here it is the four on the end. The q is the leading coefficient, which is also q. Next, find all of the factors of q and p, which since they are both 4, are ±1, ±2, and ±4. Next do all possible values of p/q, which are ±1, ±2, ±4, ±1/2, and ±1/4. These are all your possible rational zeros. complex 0s only come in pairs, so the maximum there can be is 4 complex zeros, meaning there is at least one rational, real 0. (i graphed it it is -1/2, so all others must be rational or imaginary)

Given the Coordinate R(2, -3) find R'' after the following transformations
torisob [31]

Using translation concepts, it is found that the image of point R after the transformations is given by: (1,-2).

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

The first transformation is:

(x,y) -> (x - 3, y + 5).

Hence:

(2,-3) -> (-1, 2).

For the rotation of 180º counter clockwise, the rule is:

(x,y) -> (-x,-y).

Hence the image is:

(-1,2) -> (1,-2).
