Given:

The function is:

$f(x)=-2x+5$

To find:

The inverse of the given function, then draw the graphs of function and its inverse.

Solution:

We have,

$f(x)=-2x+5$

Step 1: Substitute $f(x)=y$ .

$y=-2x+5$

Step 2: Interchange x and y.

$x=-2y+5$

Step 3: Isolate variable y.

$2y=5-x$

$y=\dfrac{5-x}{2}$

Step 4: Substitute $y=g(x)$ .

$g(x)=\dfrac{5-x}{2}$

Hence, the inverse of the given function is $g(x)=\dfrac{5-x}{2}$ and the graphs of these functions are shown below.

Asphere has a diameter of 10 in. What is the volume of the sphere?

Pavel [41]

Answer: $\frac{500}{3}$ π $in^{3}$

Step-by-step explanation: diameter=10 in

radius= $\frac{diameter}{2}$ = $\frac{10}{2}$ =5 in

volume= $\frac{4}{3}$ $r^{3}$

= $\frac{4}{3} X 5^{3}$ x π = $\frac{500}{3}$ π $in^{3}$

M ∠E = 60° and m ∠G = 85° what is m ∠L? A: 180° B: 45° C: 35° D: 85°

Viefleur [7K]

Answer:

The answer is C: 35°

Step-by-step explanation:

The sum of all angles in a triangle is 180°

So, 180°-(60°+85°)

= 180°-145°

= 35°

m∠L = 35°

Hope it helps!
