How many feet long is the shadow of a 15-foot flagpole if a 5-foot woman standing at the base of the flagpole has a shadow that
Vikentia [17]

The height of flagpole is 12.5 feet.

Step-by-step explanation:

Given,

Height of woman = 5 foot

Shadow of woman = 6 feet

Ratio of height to shadow = 5:6

Shadow of flagpole = 15 foot

Height of flagpole = x

Ratio of height to shadow = x:15

Using proportion;

Ratio of height to shadow :: Ratio of height to shadow

5:6::x:15\\

Product of mean = Product of extreme

6*x=15*5\\6x=75

Dividing both sides by 6

\frac{6x}{6}=\frac{75}{6}\\x=12.5

The height of flagpole is 12.5 feet.

The ____ of ____ property allows you to rewrite . xa· xb as xa + b.
gregori [183]
The rule of distributive property allows you to rewrite xa + xb as x (a + b).

So if x = 2, a = 3 and b = 4, xa + xb = x(a + b)
(2 * 3) + (2 * 4) = 2 (3 + 4)
6 + 8 = 14
14 = 14
...and so on. You may try it yourself with different variations.

Thank you for posting your question. I hope you found what you were after. Please feel free to ask me more.

The lengths of the sides of the triangle are 3, 8, and 10. Is the triangle a right triangle, acute triangle, or an obtuse triang
weqwewe [10]

Answer:

Obtuse

Step-by-step explanation:

  1. You have to make sure it is a triangle by adding the smallest and the medium sides, if the result is greater than the bigger side then it is a triangle.
  2. you then use the Pythagorean theorem to check if the triangle is a right triangle, acute, or obtuse. If c^{2} = a^{2} +b^{2} then it is a right triangle. If c^{2} >a^{2} + b^{2} then it is an obtuse triangle. if c^{2} < a^{2} +b^{2} then it is an acute triangle.
  1. 10^{2} _ 3^{2} + 8^{2}
  2. 9+64_100
  3. 70_100
  4. 70<100

in this case c^{2} is greater than a^{2} +b^{2} therefore, is it an obtuse triangle.

Evaluate lim x → 0+ x ln(x3). solution the given limit is indeterminate because, as x → 0+, the first factor (x) approaches 0 co
Degger [83]

\displaystyle\lim_{x\to0^+}x\ln x^3=\lim_{x\to\infty}\frac{\ln\frac1{x^3}}x=-3\lim_{x\to\infty}\frac{\ln x}x=\frac\infty\infty

L'Hopital's rule tells us the limit is equal to

-3\displaystyle\lim_{x\to\infty}\frac{\frac1x}1=0
