Answer:
Step-by-step explanation:
Well depends how old he was 2 years ago
But he would be 6 years older because 3 times as old as 2 equals 6
The length of a curve <em>C</em> parameterized by a vector function <em>r</em><em>(t)</em> = <em>x(t)</em> i + <em>y(t)</em> j over an interval <em>a</em> ≤ <em>t</em> ≤ <em>b</em> is
In this case, we have
<em>x(t)</em> = exp(<em>t</em> ) + exp(-<em>t</em> ) ==> d<em>x</em>/d<em>t</em> = exp(<em>t</em> ) - exp(-<em>t</em> )
<em>y(t)</em> = 5 - 2<em>t</em> ==> d<em>y</em>/d<em>t</em> = -2
and [<em>a</em>, <em>b</em>] = [0, 2]. The length of the curve is then
Answer:
y = 1/2x + 5
Step-by-step explanation:
Plug it in to double check, this is the correct answer.
Obtuse angles are found in a polygon.
Answer:
Solve for
x
by simplifying both sides of the inequality, then isolating the variable.
