What is the inverse of the function fx) x +3?

1 answer:

6 0

My answer -
f(x)=x^3+2 To find the inverse function f(x)^-1 , we will assume" y=x^3+2 y-2= x^3 ==> x= (y-2)^1/3 ==> f(x)-1= (x-2)^1/3
P.S

Happy to help you have an AWESOME!!!!! day

Teresa went skydiving. Teresa's height (in meters) as a function of time (in seconds) is graphed.

BabaBlast [244]

Answer:

choose B. 54 meters/second, it is closest to my calculation of 55 meters/sec

Step-by-step explanation:

To find average speed between 3 and 8 seconds, find the total distance traveled during that time.

650 meters at 3 seconds

to 375 meters at 8 seconds

then average speed = ( 650 - 375 ) / (8 - 3) = 275 /5 = 55 meters /sec

Y=x2−6x+10 y=4−x How do I substitute?

Shtirlitz [24]

Answer:

(2,2) and (3,1)

Step-by-step explanation:

Since we're given the value of y in the second equation, we can replace the y on the left side of the first equation with 4-x, giving us

$4-x=x^2-6x+10\\0=x^2-5x+6$

We can factor the expression on the right to get us

$0=x^2-5x+6\\0=x^2-3x-2x+6\\0=x(x-3)-2(x-3)\\0=(x-2)(x-3)$

Solving $x-2=0$ and $x-3=0$ gets us the solutions $x=2,3$ , which we can plug into the second equation to get us

$y=4-2=2\\y=4-3=1$

So, our solution set is the pair of points (2,2) and (3,1)

The diameter of each wheel of a bicycle is 27 inches. If you are traveling at a speed of 20 miles per hour on this bicycle, thro

klasskru [66]

Notice, you've got a diameter in inches
and a linear velocity in miles
thus, you'd need to convert first

$\bf v=rw\implies \cfrac{v}{r}=w\qquad 
\begin{cases}
v=\textit{linear speed}\\
r=radius\\
w=\textit{angular speed}\\
 --------------\\
v=20\frac{mi}{h}\\
r=\frac{diameter}{2}=\frac{27}{2}
\end{cases}
\\\\
\textit{now, converting 20miles to inches}
\\\\
\cfrac{20mi}{h}\cdot \cfrac{5280ft}{mi}\cdot \cfrac{12in}{ft}\implies \cfrac{20\cdot 5280\cdot 12\ in}{h}\impliedby v
\\\\\\
\cfrac{1267200\frac{in}{h}}{\frac{27}{2}in}=w$

now, whatever that is, you'll need to divide it by a revolution, recall, a revolution is $2\pi$
thus $\bf \cfrac{\qquad \boxed{\cfrac{1267200\frac{in}{h}}{\frac{27}{2}in}}\qquad }{2\pi }=revolutions$

Instructions: Find the value of 2.

frosja888 [35]

Answer:

x = 50°

2x = 100°

Step-by-step explanation:

Chords AB and DC are equidistant (3 units) from the center E of the circle.

Since, the chords equidistant from the center of the circle are congruent.

Congruent chords intercepts congruent arcs.

Hence, x = 50°

2x = 2*50° = 100°
