ikadub [295]

The question is incomplete, the complete question is below:

Scientists have found a relationship between the temperature and the height above a distant planet's surface. , given below, is the temperature in Celsius at a height of kilometers above the planet's surface. The relationship is as follows: T(h) = 30.5 -2.5h.

a) Calculate T^-1(x)

b) T^-1(15)

Answer:

a) T^{-1} (x)= \frac{30.5-x}{2.5}

b) 6.2 °C

Step-by-step explanation:

a) T(h) = 30.5 - 2.5h\\2.5h = 30.5-T(h)\\h = \frac{30.5-T(h)}{2.5}\\ T^{-1} (x)= \frac{30.5-x}{2.5}

b) T^{-1} (x)= \frac{30.5-x}{2.5}\\\\T^{-1} (15)= \frac{30.5-15}{2.5}=6.2

How do i find the sin 11pi/2 without using a calculator?
Basile [38]
The values of sin cycle on the domain 0 to 2π
The value of sin(π/2) = 1
The value of sin(2π/2) = 0
The value of sin(3π/2) = sin(π + π/2)= -1
Therefore, if the angle can be written as:
nπ + π/2, where n is any odd number, the value of sin(nπ + π/2) = -1
sin(11π/2) = sin(5π + π/2) = -1
