Answer:
Because it can be shaped to make things magnified
58 to x should be the ratio of 6/3 or 1/2 if they are similar.
Find out how much bigger 58 is compared to 6, the matching side on the other polygon.
58/6 = ~9.7
The x side should be half of this, just like it is on the smaller polygon.
9.7/2 = 4.85
4.85 x 3 = 14.55
Answer:
a. Types of computer software used in a database management system. =Qualitative
b. Life-lengths of laser printers =Quantitative
c. Brands of calculators used by 100 engineering students on campus =Qualitative
d. Mileage attained by 12 automobiles powered by alcohol= Quantitative
Step-by-step explanation:
Data is described as quantitative when it deals with numeric values whereas qualitative data is categorical in nature. Quantitative data tells us how much, how many, or the frequency of occurrence of certain variables. Qualitative data provides answers to the what, why, which, and where questions.
1. Types of computer software are not numeric variables as they answer the 'what' question.
2. Length deals with numbers, so the life-lengths of laser printers is a quantitative variable.
3. Brands of calculators are categorical data and are thus qualitative.
4. Mileage is a numerical variable and is thus quantitative.
Answer:
Using trigonometric ratio:
From the given statement:
and sin < 0
⇒
lies in the 3rd quadrant.
then;
Using trigonometry identities:
Substitute the given values we have;
Since, sin < 0
⇒
now, find 
:
Substitute the given values we have;
Therefore, the exact value of:
(a)
(b)
