Given:

d(t)=80t

C(d)=0.09d

To find:

The value of C(d(10)).

Solution:

We have,

C(d(10))=C(80(10))           [\because d(t)=80t]

C(d(10))=C(800)

Now,

C(d(10))=0.09(800)           [\because C(d)=0.09d]

C(d(10))=72

Therefore, the value of C(d(10)) is 72.

<h3>Answer : y = ⅚x - 3</h3>

════════════════════

<h3>Known</h3>

x1 = 6

y1 = 2

x2 = (-6)

y2 = (-8)

════════════════════

<h3>Question</h3>

Equation of the line (y = mx + c)

════════════════════

<h3>Way to do</h3>

#First, you find the gradient (m)

m =  \frac{y2 - y1}{x2 - x1}  =  \frac{(( - 8) - 2)}{(( - 6) - 6)}  =  \frac{( - 10)}{( - 12)}  =  \frac{5}{6}

#Now use the formula of equation of the line

y - y1 = m(x - x1)

y - 2 = ⅚(x - 6)

y - 2 = ⅚x - 5

y = ⅚x - 5+2

y = ⅚x - 3

netineya [11]
Here's what you need to know in order to answer this:

       1 gallon  =  128 fl oz
and      
       1 day  =  24 hours. 
    
Use those facts to invent fractions equal to ' 1 '.
Then use those to change the units of the "11 fl oz per hour".
You can multiply them ... since their value is ' 1 ', they won't
change the value of the "11 fl oz per hour", only the units.

                  (11 fl oz/hr) x (24 hr/da) x (1 gal / 128 fl oz)

               = (11 x 24 x 1 / 128)  (fl-oz - hr - gal) / (hr - da - fl-oz)

               =         2.0625                        gal/da
