Answer:
perpendicular = 10.24 cm
Step-by-step explanation:
by pythagorus theorem,

( where, h = hypotenuse, b = base,
p = perpendicular )
so,

perpendicular = 10.24 ( root 105 )
Answer:
32°
Step-by-step explanation:
The triangle ABC is a isosceles so angle A = angle C
The sum of interior angles in a triangle is = 180°
74 + 74 + angle B = 180
B = 32°
Answer:
The function given is:
P(x) = 15x² + 350x - 2000
or
y = 15x² + 350x - 2000
Interchange x and y:
x = 15y² + 350y - 2000
x = (y√15)² + 2(y√15)(45.19) + (45.19)² - (45.19)² - 2000
x = ( y√15 + 45.19)² - 4042.14
( y√15 + 45.19)² = x + 4042.14
Take square root:
y√15 + 45.19 = (√(x + 4042.14))
y√15 = (√(x + 4042.14)) - 45.19


The minimum value of x, for which function is defined and real, is x= -4042.14
Hence, the range of inverse is x ≥ -4042.14
