The variable z is inversely proportional to x. When x is 6, z has the value 0.5. What is the value of z when x= 14?

Lilit [14]

Z is inversely proportional to X is the same as
z is directly proportional to 1/X
which can be written like this:-
y=k/X
________
0.5=k/6
0.5*6=k/6*6
k=3 ;
________
z = 3/14
Z = 0.2

1. Draw the graph of f(x) = cos x for 0 I know how to construct the graph but I don’t know how to get the figures. Please help

KengaRu [80]

Answer:

Please refer to the attached figure.

Step-by-step explanation:

Given the function:

$f(x) =cosx \ where\ \{0^\circ\leq x\leq 360^\circ\}$

OR, the given function can also be written as:

$y = f(x) = cosx$

We know that graph of cosine is a wave.

and the range of cosine function is [-1, 1]

First of all, let us have a table of values at major values of x.

$x = 0, f(x) = 1\\x = 90, f(x) = 0\\x = 180, f(x) = -1\\x = 270, f(x) = 0\\x = 360, f(x) = 1$

So, the table of values for f(x) is:

$\begin{center}\begin{tabular}{ c c }x & cosx \\0 & 1 \\90 & 0\\180 & -1\\270 & 0\\360 & 1\\\end{tabular}\end{center}$

Let us mark these points on the xy coordinate axis where x axis represents value of x and y axis represents value of $f(x) = cosx$ and then join the points using a wave.

Market Basket sells chocolate chip cookies . A-Best cookies are 12 cookies for $6.00. A- Okay cookies sell 20 cookies for $ 8.00

agasfer [191]

The unit price for best cookies is $0.5

The unit price for Okay cookies is $0.4

Step-by-step explanation:

The unit cost is obtained by dividing the total cost by the quantity

Given

Best Cookies:

Cost = $6.00

Quantity = 12

So the unit price will be:

$Unit\ price\ for\ best\ cookies = \frac{6}{12}\\=0.5\ dollars\ or\ 50\ cents$

Okay Cookies:

Cost = $8.00

Quantity = 20

The unit price is:

$Unit\ price\ of\ okay\ cookies = \frac{8}{20}\\= 0.4 \dollars\ or\ 40\ cents$

The unit price for best cookies is $0.5

The unit price for Okay cookies is $0.4
