A polynomial is a collection of terms that are separated by a plus or a minus sign. There a few types of polynomials.
Monomials have one term.
Binomials have two terms.
Trinomials have three terms.
All of these are classified as a polynomial.
Once you go over 3 terms, it's simply called a polynomial.
Answer:
1. -15x + 60 <= 105 2. 14x + 11 <= - 31
Step-by-step explanation:
1. x> = - 3
2. x <= - 3
Isolate the variable by dividing each side by factors that don't contain the variable
Positive 28 because to negative will equal a positive number
Answer:
12
Step-by-step explanation:
Using the 30-60-90 triangle formula side AB would be double of side CB.
We are given a concave spherical mirror with the following dimensions:
Radius = 60 cm; D o = 30 cm
Height = 6 cm; h o = 6 cm
First, we need to know the focal length, f, of the object (this should be given). Then we can use the following formulas for calculation:
Assume f = 10 cm
1/ f = 1 /d o + 1 / d i
1 / 10 = 1 / 30 + 1 / d i
d i = 15 cm
Then, calculate for h i:
h i / h o = - d i / d o
h i / 6 = - 15 / 30
h i = - 3 cm
Therefore, the distance of the object from the mirror is 3 centimeters. The negative sign means it is "inverted".
