Since given to costs, you can find the equation to model the Canoe cost.(110-80)/(4-2)=15, cost=15(hour)+b. Plugging in $80/2 hours. B= $50. The equation is cost=15*hour+50. Rate of change will be $15 an hour

The answer is 355 houses, but can someone tell me how please?

Ymorist [56]

So you do 20%*426 to get 85.2 then you would subtract 85.2 from 426 because they sold 20% more than last year. On top of that the answer isn't 355 it is 340.8.

Charles will babysit for up to 4 hours and charges $7 per hour. Write a function in function notation for this situation.

I am Lyosha [343]

Assume Charles charges $7*3=$21 if he babysits for 2,5 hours (that is 2 and a half hours).

That is we are not considering Charles babysitting exactly 1, 2, 3 or 4 hours, but also in between times.

then we can write the following piecewise function to describe the situation:

f is a function from (0, 4] to {$7, $14, $21, $28}

$f(x)=\begin{cases} 
 \$7 & if \enspace \enspace x\leq 1 \\
 \$14 & if \enspace \enspace 1\ \textless \ x\leq 2 \\
 \$21 & if \enspace\enspace 2\ \textless \ x\leq 3 \\
 \$28 & if \enspace\enspace 3\ \textless \ x\leq 4 \
 \end{cases}$

BC = 6 km

<u>/</u><u> </u> ACB = 34°

AC = ?

cos 34° = $\frac{BC}{AC}$
