X+x²=30
x²+x-30=0
(x+6)(x-5)=0
x=-6 or x=5
According to the graph given, and using it's concept, it is found that the initial value of the domain is of 0.
The <em>domain</em> of a function is the <u>set that contains all possible input values</u>.
- In a graph, it is <u>represented by the values of x</u>, which is the horizontal axis.
In the graph given in this problem, the function is <u>defined for x between 0 and 2</u>, that is, the <em>domain </em>is [0,2], hence, the initial value of the domain is of 0.

Answer:
0.16
Step-by-step explanation:
It's a binomial. It's obvious hence the prefix "bi-" means 2.
Answer:84
Step-by-step explanation:Using proportions, it is found that the height of the lighthouse is of 84 ft.
This question is solved by proportions, using a rule of three.
For a height of 5.25 feet, the shadow is of 8 feet. What is the height when the shadow is of 128 feet?
The rule of three is:
5.25 feet - 8 feet
x feet - 128 feet
Applying cross multiplication:
The height of the lighthouse is of 84 ft.
