Answer:
19.9875 feet
Step-by-step explanation:
The formula is given as:
Shadow of the student/Height of the student = Shadow of the telephone pole/Height of the telephone pole.
1 inch = 0.0833 feet
Shadow of the student = 5ft
Height of the student = 5 feet 4 inches
4 inches to feet
= 4 × 0.0833 feet
= 0.33 feet
Hence: Height of the student = 5 + 0.33 = 5.33 feet
Shadow of the telephone pole = 18 feet 9 inches long
9 inches to feet
= 9 × 0.0833 feet
= 0.75 feet
Hence: Shadow of the telephone pole = 18 + 0.75 = 18.75 feet
Height of the telephone pole= x
Therefore:
5/5.33 = 18.75/x
Cross Multiply
5x = 5.33 × 18.75
x = 5.33 × 18.75/5
x = 19.9875 feet
The height of the telephone pole = 19.9875 feet
Answer:
<em>Domain={2,5,8}</em>
<em>Range={1,3,6}</em>
<em>Function: YES</em>
Step-by-step explanation:
<u>The Domain of a Function
</u>
Is the set of values the input variable x takes.
<u>Range of a Function
</u>
It's the set of values the output function takes when x moves into the function's domain.
A function is a relation between an input and an output set of values with the condition that every element in the domain relates only with one element in the range.
Following the definitions above, the domain of the relationship is the set of input values:
Domain={2,5,8}
The range is the set of output values:
Range={1,3,6}
Since each element in the input set is related only to one element in the range, the given relationship is a function.
Answers:
Domain={2,5,8}
Range={1,3,6}
Function: YES
Ratios are the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
Equivalent ratios are like equivalent fractions, if they are the same value they are equivalent.
For example, to find two ratios that are equal to 1:7, first write 1:7 as the fraction 1/7.
