Calculate the length of DE.

CaHeK987 [17]

set up the proportion, cross multiply, and solve for the missing length.

$\frac{BA}{BE} = \frac{DC}{DE}$

$\frac{6}{3} = \frac{9}{DE}$

6(DE) = 3(9)

DE = $\frac{3(9)}{6} = \frac{9}{2} = 4.5$

Answer: 4.5

Suppose f left parenthesis x right parenthesis right arrow 150f(x)→150 and g left parenthesis x right parenthesis right arrow 0g

BigorU [14]

Answer:

$\lim_{x \to 3} (\frac{f(x)}{g(x)} )=- \infty$

Step-by-step explanation:

Given that:

f(x) approaches 150, and

g(x) approaches 0, with g(x) < 0,

as x approaches 3.

This means:

$\lim_{x \to 3} f(x)=150 \\\\ \lim_{x \to 3} g(x)=0$

We need to evaluate:

$\lim_{x \to 3} (\frac{f(x)}{g(x)} )$

Distributing the limit to numerator and denominator, we get:

$\frac{ \lim_{x \to 0} f(x) }{ \lim_{x \to 0} g(x)}\\\\ = \frac{150}{0}$

The expression will result in infinity as the answer, but since, g(x) < 0, this means g(x) is approaching 0 from the negative side. As a result, the expression 150/0 will approach negative infinity as x will approach 3.

Therefore, we can conclude:

$\lim_{x \to 3} (\frac{f(x)}{g(x)} )=- \infty$

A student would like to find the height of a statue. The length of the statue's right arm is 54 feet. The student's right arm

Komok [63]

Answer:

a) Approximate height of the statue: 144 feet

b) The approximate height is 1.7% greater that the actual height of the statue.

Explanation

1) Assume that the measures of the statue are proportional to the dimensions of the student. That means:

statue's height student's height

________________________ = ______________________

length of the statue's right arm length of student's right arm

⇒ x / 54 feet = (5 + 1/3) feet / 2 feet

⇒ x = 54 × (16/3) / 2 feet = (54×16) / (3×2) feet = 144 feet

Answer: 144 feet

2) Compare the approximate heigth obtained with the actual height:

144 feet - (143 feet + 9 inches) = 144 feet - (143 feet + 9/12 feet) = 1 feet - 9/12 feet

1 feet - 9/12 feet = 1 feet - 3/4 feet = 1/4 feet.

Hence, the approximate feet obtained is 1/4 feet larger than the actual height.

In relative terms that is : (1/4) / (143 + 3/4) = 0.0017 = 1.7%.
