PLEASE ANSWER!! <br> The graph below have the same shape. what is the equation for the red graph?

Serga [27]

Answer:

Step-by-step explanation:

given a function f(x) then

f(x) + c ← denotes a vertical translation of f(x)

• If c > 0 then shift vertically up

• If c < 0 then shift vertically down

Here the vertex of f(x) is at the origin and the vertex of g(x) is (0, 3 ), that is 3 units vertically up

Hence g(x) = x² + 3 → C

A juggler tosses a bowling pin in the air with an initial velocity of 18 ft per second. It leaves his hand when it is five feet

Natali5045456 [20]

Complete Question

A juggler tosses a bowling pin in the air with an initial velocity of 18 ft per second. It leaves his hand when it is five feet from the ground and he catches it when it is four feet from the ground,How long is the ball in the air?

Answer:

$t\approx 0.1s$

Step-by-step explanation:

From the question we are told that

Initial velocity $V_0= 18 ft/s$

Initial Height $h_1=5feet$

Final Height $h_2=4feet$

Generally the Newtons equation for motion is mathematically given by

$V^2 = U^2 + 2as$

Where

$s=h_2-h_1\\s=4-5\\s=-1ft$

And

$a=g=>9.81\\a=32.2ft/s^2$

Therefore

$V^2 = (18)^2 + 2(-32.2)(-1)$

$V^2 = 388.4$

$V =19.70786645\\V=19.71ft/s$

Generally the equation for Time is mathematically Given as

$t=\frac{V-U}{a}$

$t=\frac{19.71-18}{32.2}$

$t=0.05310559006$

$t\approx 0.1s$

Therefore the time spent on air by the ball is

$t=0.05310559006s$

Show that x=2 is a solution of the equation X^3-x-6

My name is Ann [436]

Answer:

x = 2 is the solution of x^3 - x - 6

Step-by-step explanation:

(x^3) - x - 6 = 0

If x = 2,

--> (2^3) - 2 - 6

= 8 - 2 - 6 = 8 - 8 = 0.
