Answer:
3x - 4y= -17 or slope intercept form is y= 
Step-by-step explanation:
Use the Ax+By=C equation
(a) Differentiate each of the components to get r'(t). The rule is
.. d/dt (a*e^(bt)) = a*b*e^(bt)
The answer you have shown is the correct one.
(b) See the figure. The red curve is the position r(t) for 0 ≤ t ≤ 2. The dashed orange line is the tangent line, whose equation is
.. L(t) = r(0) +r'(0)*t = (2 +2t)i +(3 -3t)j
Around 70mph count 50miles per 10mph and you’ll get 70mph by the you hit 350miles
Answer:
$190 is the answer
minus $5 from $97.50 and add that number to $97.50
