the shadow cast by a 72-inch tall fence post is of 125 inch!
<u>Step-by-step explanation:</u>
Here we have , The sun shines at a 30° angle to the ground. To the nearest inch, We need to find how long is the shadow cast by a 72-inch tall fence post. Let's find out:
According to question we have a right angle triangle with following parameters :
We know that
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Rounding off we get :
⇒ 
Therefore , the shadow cast by a 72-inch tall fence post is of 125 inch!
Answer:
multiply a by 2 divide a and 3
When you plot the points and use the vertical line test, you'll see that none of the vertical lines go through two points. Therefore verifying that this set of points represents a function.
Answer:
Approximately 17.88x or 
Step-by-step explanation:
Use pythagorean formula. In a rhombus the diagonals bisect each other and they are perpendicular, so you could have a right triangle with legs of 2x and 4x, the hypoteneuse would then be 
which is approximately 4.47x. In a rhombus all 4 sides are the same, so multiply that by 4 and you get the perimeter. 4(4.47x) = 17.88x or if you simplify the radical instead it's
Answer:
Step-by-step explanation:
if you know 50*4=200, you must also know that 50*10=500 and that 4*100=400 so 500*400= 50*10*4*100
multiplication is comutative so
50*4*10*100=200*1,000= 200, 000
