Answer:

Although the constant on the right side is negative does not mean there is no solution. Because the negative nine is outside the absolute value, the solution can exist.

The function a(t)=t^(1/2)−t^(−1/2) m/s^2 represents the acceleration of a particle moving along a horizontal axis. At time t=0,

garri49 [273]

Answer:

see below

Step-by-step explanation:

a(t)=t^(1/2)−t^(−1/2)

We integrate to find the velocity

v(t) = integral t^(1/2)−t^(−1/2) dt

= t ^ (1/2 +1) t ^ (-1/2 +1)

------------ - ----------------- + c where c is the constant of integration

3/2 1/2

v(t) = 2/3 t^ 3/2 - 2 t^ 1/2 +c

We find c by letting t=0 since we know the velocity is 4/3 when t=0

v(0) = 2/3 0^ 3/2 - 2 0^ 1/2 +c = 4/3

0+c =4/3

c = 4/3

v(t) = 2/3 t^ 3/2 - 2 t^ 1/2 +4/3

To find the position function we need to integrate the velocity

p(t) = integral 2/3 t^ 3/2 - 2 t^ 1/2 +4/3 dt

2/3 t ^ (3/2 +1) 2 t ^ (1/2 +1) 4/3t

------------ - ----------------- + ------------- + c

5/2 3/2 1

p(t) = 4/15 t^ 5/2 - 4/3t ^ 3/2 + 4/3t +c

We find c by letting t=0 since we know the position is -4/15 when t=0

p(0) = 4/15 0^ 5/2 - 4/3 0 ^ 3/2 + 4/3*0 +c = -4/15

0 +c = -4/15

c = -4/15

p(t) = 4/15 t^ 5/2 - 4/3t ^ 3/2 + 4/3t -4/15

The function f(x) is shown in this graph

gtnhenbr [62]

Answer:

The correct statement is:

The slope of f(x) is same as the slope of g(x)

Step-by-step explanation:

We see that the graph of the function f(x) is a line that passes through (0,2) and (1,-1)

Hence, the equation of the function f(x) is calculated by a two-point formula as:

$y-2=\dfrac{-1-2}{1-0}\times (x-0)\\\\y-2=\dfrac{-3}{1}\times x\\\\y-2=-3x\\\\y=-3x+2$

( On comparing the equation of f(x) with slope intercept form.

i.e. y=mx+c

where m is the slope and c is the y-intercept)

We get slope of f(x)= -3

and y-intercept= 2

The function g(x) is given by:

$g(x)=-3x-6$

Hence, slope of g(x) = -3

and y-intercept= -6

Hence, we get that the slope of f(x) and g(x) is same.

( i.e. -3)

What is the equation of the graph below?

Citrus2011 [14]

Answer:

Step-by-step explanation:

the standard form of a sine wave is

y = asinbx + c

where a is the amplitude , period = $\frac{2\pi }{b}$ and c is the vertical shift

a = $\frac{max-min}{2}$ = $\frac{1-(-1)}{2}$ = 1

period = $\frac{2\pi }{3}$

b = $\frac{2\pi }{\frac{2\pi }{3} }$ = 3 , c = 0

hence y = sin 3x is the equation of graph
