Answer:
12
Step-by-step explanation:
Side 9 applies to side 18
Side 7 applies to side 14
the factor is multiply by two
So 6 times 2 is 12
They are using the point (2, 8) to write this equation. You know that because of the "y-8" in the equation, and also because it's bolded! lol. Anyways, what's missing is the slope and the x value from our point. The slope is -2. Find this by picking 2 points on the line and putting those into the slope equation. Use the bolded point and the x-intercept: (2,8) and (6,0):
. As stated earlier the x coordinate in the bolded point is 2. So our equation is y-8=-2(x-2). And there you Go!
Answer:
38.6m
Step-by-step explanation:
Theory of solving angle of elevation problem bus to take it as a right angle triangle.
The length of the the rope is the hypotenuse and the angle formed is the hypotenuse angle.
To determine the height , we take the side as opposite the angle.
Sin (angle) = height/hypotenus
Sin40= height/60
0.6428 *60 = height
38.568 = height
Approximately 38.6m
Since 5 is positive and it is one of the counting numbers, 5 is a rational, integer and natural number. 5 is not an irrational number.
Since 1/4 is a rational number, 1/4 is not an irrational number
Since 1.25 is a rational number, 1.25 is not an irrational number.
