A particle moves in a straight line so that its velocity at time

riadik2000 [5.3K]

Answer:

s(2) = 7.75

Step-by-step explanation:

given the velocity v(t) = t^3

we can find the position s(t) by simply integrating v(t) and using the boundary conditions s(1)=2

$s(t) = \int {v(t)} \, dt\\ s(t) = \int {t^3} \, dt\\s(t) = \dfrac{t^4}{4}+c$

we know throught s(1) = 2, that at t=1, s =2. we can use this to find the value of the constant c.

$s(1) = \dfrac{1^4}{4}+c\\4 = \dfrac{1^4}{4}+c\\c = 4-\dfrac{1}{4}\\c = \dfrac{15}{4} = 3.75$

Now we can use this value of t to formulate the position function s(t):

$s(t) = \dfrac{t^4}{4}+\dfrac{15}{4}\\$

this is the position at time t.

to find the position at t=2

$s(2) = \dfrac{2^4}{4}+\dfrac{15}{4}\\$

$s(2) = \dfrac{31}{4} = 7.75$

the position of the particle at time, t =2 is s(2) = 7.75

Decide which of the two given prices is the better deal and why. You can buy shampoo in a 6 ounce bottle for $2.49 or in a 14 ou

LenaWriter [7]

The cost per ounce of the first bottle is $0.415 and the second bottle is $0.699.

The first bottle has the better deal because if you were to have 14 ounces of the first type of shampoo, it would only cost $5.81

22. MULTIPLE CHOICE What number is 0.02% of 50? (Skills Review Handbook) (A) 0.01 (B) 0.1 (C) 1 (D) 100

emmainna [20.7K]

Answer:

$x = 1$

Then the answer is C

Step-by-step explanation:

1) Set a linear equation

$\frac{2}{100} = \frac{x}{50}$

2) Cross multiply

$100x = 2 \times 50$

3) Multiple the right side

$100x = 100$

4) Divide both side by 2

$\frac{100x}{100} = \frac{100}{100}$

5) Solving the linear equation

$x = 1$

The answer is (C)

The $1 coin here depicts Sacagawea and her infant son. The diameter of the coin is 26.5 millimeters. Find the circumference. Use

Nikolay [14]

Answer:
83.21 mm.

Explanation:
Circumference of a circle is is found by using the formula:
C=πd.
C is the Circumference.
d is diameter.
π is the ratio for Pi,

In this case we will use:
3.14 instead of π
d = 26.5 mm

Plug in the known values. 
C=(3.14)(26.5) = 83.21 mm
