Answer:

Step-by-step explanation:

The minimum number required is the least common multiple (LCM) of 15 and 4. The numbers 15 and 4 have no common factors, so their LCM is their product.

15×4 = 60 strands are required

State the chain rule for the derivative dy/dt if y(t)=f(u(t))(chain of f and u)

Ann [662]

Answer:

$\displaystyle\frac{d(y(t))}{dt} =\displaystyle\frac{d(f(u(t)))}{dt} = f'(u(t)).u'(t)$

Step-by-step explanation:

The chain rule helps us to differentiate functions and a composition of two functions.

Let r(u) and s(u) be two function. Then, composition of these two functions can be be differentiated with the help of chain rule. It states that:

$\displaystyle\frac{d(r(s(u)))}{du} = r'(g(u)).s'(u)$

Now, we are given

$y(t) = f(u(t))$

Then, by chain rule, we have:

$\displaystyle\frac{d(y(t))}{dt} =\displaystyle\frac{d(f(u(t)))}{dt} = f'(u(t)).u'(t)$

In fifteen minutes, greg's sailboat went 3/6 mile, gina's sailboat went 6/6 mile, and Stuart's sailboat went 4/6 mile. Whose sai

Radda [10]

To make this situation easier to understand, you must simplify these fractions. 3/6 is equal to 0.5
6/6 is equal to 1
4/6 is equal to 0.3333 repeating.

With this info we can tell that Gina's sailboat went to longest distant in the fifteen minutes.

Hope this helps! :)

Answer:

Slope = -3

y-intercept = (0,-4)

Equation: y = -3x-4

Step-by-step explanation:

We can take any two input-output pairs from the table to find the equation of given function.

Linear function is given by:

$y =mx+b$

Here m is the gradient of the functions which is defined as:

$m = \frac{rise}{run} = \frac{y_2-y_1}{x_2-x_1}$

The input-output pairs are:

(x1,y1) = (-1,-1)

(x2,y2) = (0,-4)

First of all,

$m = \frac{-4-(-1)}{0-(-1)}\\= \frac{-4+1}{1} = -3$

Putting the value of slope in the equation

$y = -3x+b$

Putting (-1,-1) in the equation

$-1 = -3(-1)+b\\-1 = 3+b\\b = -1-3\\b = -4$

The equation will be:

$y = -3x-4$

Hence,

Slope = -3

y-intercept = (0,-4)

Equation: y = -3x-4

Al's awesome autos advertised a special sale on cars - Dealer cost plus 5%!! Jack and Margaret boughta luxury sedan for $23,727.

Marat540 [252]

05/23727.90=100/x
105x=23727.90x100
105x=2372790
(105x)/105=2372790/105
x=22598

dealers cost is $22,598

<span>the 105% is the 100% price of the car plus the 5% of that tax</span>
