A scale factor is a number multiplied to a certain number to determine the magnification of the quantity if the data. This is used to relate the effect of changing one parameter to the dependent variable. For example, if the temperature is doubled, then the volume increases by a factor of 2. To know the second volume, just multiply the first volume by 2.
So, an expansion factor must be more than 1. The greater the number, the greater the extent of expansion. Otherwise, if the factor is expression in proper fractions, the number is then reduced. The negative sign actually does not matter because it might be a vector quantity that expresses only the direction of motion, for example. From the choices, there are two fractions: 2/3 or 3/2. But since 3/2 is an improper fraction and is equal to 1.5, it is expansion because the factor is more than 1. Therefore, the scale factor for reduction is 2/3.
3:7, Basically simplifying it.
Answer is 70 because one pound is 16 ounces and you do 16+16+16+16+4+2=70
Answer: The required polynomial of lowest degree is 
Step-by-step explanation: We are given to find a polynomial function of lowest degree with real coefficients having zeroes of 2 and -5i.
We know that
if x = a is a zero of a real polynomial function p(x), then (x - a) is a factor of the polynomial p(x).
So, according to the given information, (x - 2) and ( x + 5i) are the factors of the given polynomial.
Also, we know that complex zeroes occur in conjugate pairs, so 5i will also be a zero of the given polynomial.
This implies that (x - 5i) is also a factor of the given polynomial.
Therefore, the polynomial of lowest degree (three) with real coefficients having zeroes of 2 and -5i is given by
Thus, the required polynomial of lowest degree is
