D - All real numbers. Domain for 99% of the time will be all real numbers
The tower will be represented by AB and BC is the base of the tower to the point 750 ft. The angle of elevation is α.
the value of α will be given by:
tan α=(AB)/(BC)
AB=1454 ft
BC=750 ft
hence:
tan α=750/1454
tan α=0.5158
thus
α=arctan 0.5158
α=27.2855~27.3°
84/100. 42/50. 21/25. And there not sure though
Answer:
25x^2 -1
Step-by-step explanation:
If you multiply parentheses:
(5x*5x) + (5x*-1) + (1*5x) + (1*-1)
25x^2 - 5x + 5x -1
25x^2 -1
A simpler way is to memorize this formula
(Square1 - square2)= (sqrt of square1- sqrt of square2)*(sqrt of square1 + sqrt of sqaure2)
Answer:
Number of hours, x Number of miles, y
0.5 5
1 10
1.5 15
2 20
2.5 25
Step-by-step explanation:
-Distance is the product of speed by time.
-The speed is given as 10mph. The distance equation is therefore given as:
The quotient of in the third table gives as the constant 10 for all rows:
Hence, the 3rd table represents the correct values of both y, miles and hours, x.
