one the first one the sign flipped because you divided by a negative number, on the third one it was all real numbers because the coefficients of n (which was "3") are equal and 3n+15 is greater than or equal to 3n+8 no matter what number you put in

The velocity function, in feet per second, is given for a particle moving along a straight line. Find (a) the displacement and (
AveGali [126]

Answer:

(a) 2 feet.

(b) 2 feet.

Step-by-step explanation:

We have been given that the velocity function v(t)=\frac{1}{\sqrt{t}} in feet per second, is given for a particle moving along a straight line.

(a) We are asked to find the displacement over the interval 1\leq t\leq 4.

Since velocity is derivative of position function , so to find the displacement (position shift) from the velocity function, we need to integrate the velocity function.

\int\limits^b_a {v(t)} \, dt

\int\limits^4_1 {\frac{1}{\sqrt{t}}} \, dt

\int\limits^4_1 {\frac{1}{t^{\frac{1}{2}}} \, dt

\int\limits^4_1 t^{-\frac{1}{2}} \, dt

Using power rule, we will get:

\left[\frac{t^{-\frac{1}{2}+1}}{-\frac{1}{2}+1}}\right] ^4_1

\left[\frac{t^{\frac{1}{2}}}{\frac{1}{2}}}\right] ^4_1

\left[2t^{\frac{1}{2}}\right] ^4_1  

2(4)^{\frac{1}{2}}-2(1)^{\frac{1}{2}}=2(2)-2=4-2=2

Therefore, the total displacement on the interval  1\leq t\leq 4 would be 2 feet.

(b). For distance we need to integrate the absolute value of the velocity function.

\int\limits^b_a |{v(t)|} \, dt

\int\limits^4_1 |{\frac{1}{\sqrt{t}}}| \, dt

Since square root is not defined for negative numbers, so our integral would be \int\limits^4_1 {\frac{1}{\sqrt{t}}} \, dt.

We already figured out that the value of \int\limits^4_1 {\frac{1}{\sqrt{t}}} \, dt is 2 feet, therefore, the total distance over the interval 1\leq t\leq 4 would be 2 feet.

<u>Algebra I</u>

  • Function Notation

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 3x - 2

g(x) = x² - 5

<u>Step 2: Find g(f(2))</u>

f(2)

  1. Substitute in <em>x</em>:                    f(2) = 3(2) - 2
  2. Multiply:                               f(2) = 6 - 2
  3. Subtract:                              f(2) = 4

g(f(2))

  1. Substitute in <em>x</em>:                    g(4) = 4² - 5
  2. Exponents:                          g(4) = 16 - 5
  3. Subtract:                              g(4) = 11
