Hello,

The exosphere is the lowest<span> in density of the </span>layers of the atmosphere.

The higher up you get into the atmosphere, the lower the density becomes. Thus, the troposphere has the highest density of the five layers.

If f^-1(y) is the inverse of f(x) which statements must be true?

Salsk061 [2.6K]

Let us assume f(x) = 2x - 5
f⁻¹(x) = (x + 5)/2
f(f⁻¹(x)) = 2((x + 5)/2) - 5 = x
f⁻¹(f(x)) = (2x - 5 + 5)/2 = x
The domain of a function is the range of its inverse and vice versa
The range of a function is the domain of its inverse and vice versa
Therefore, statements A, B, D and E are true

Calculate accelerationof the following. calcutale the acceleration of josh rding his biycle in a straight line that speeds up fr

BartSMP [9]

Explanation:

Wooho Physics my favorite subject! And my 100th answer :)

We will use the formula

$\boxed{\tt{ Acceleration = \dfrac{v - u}{t}}}$

Where v is Final velocity
And u is Initial velocity.
t is time taken.

In this question :-

u is 4 m/s
v is 6 m/s
t is 5 seconds

Applying the formula:-

$\sf{ Acceleration = \dfrac{6 - 4}{5}}$

$\sf{ Acceleration = \dfrac{2}{5}}$

So, Acceleration is 0.4 m/s² is the answer.

Hope it helps :)

juin [17]

Answer:

Following are the solution to this question:

Explanation:

Law:

$\to \theta= 180^{\circ}- 50^{\circ}- 25^{\circ}$

$= 180^{\circ}- 75^{\circ}\\\\= 105^{\circ}$

$\to \frac{T_{L}}{\sin (90+50)}= \frac{T_{R}}{\sin (25+90)}=\frac{1400}{\sin (105)}$

$\to T_L=931.65 \ pounds \\\\ \to T_R=1313.59 \ pounds \\\\$
