Micaela and Chelsea each improved their yards by planting rose bushes and ivy. They bought their supplies

kifflom [539]

Answer:

Step-by-step explanation:

Let:

i: the cost of one pot of ivy.

r: the cost of one rose bush

$5r+3i=58 ......(1)\\5r+10i=100.......(2)\\\\$

From eq(1) we can get:

$r=\frac{58-3i}{5} \\$

Substitute eq(1) in eq(2):

$5(\frac{58-3i}{5})+10i=100\\58-3i+10i=100\\7i=100-58\\i=\frac{42}{7} =6\\$

$r=\frac{58-3i}{5} \\r=\frac{58-3(6)}{5} \\\\r=8$

Let r(t)=⟨t2,1−t,4t⟩. calculate the derivative of r(t)⋅a(t) at t=5, assuming that a(5)=⟨−4,4,−5⟩ and a′(5)=⟨−5,9,3⟩

erastovalidia [21]

$\mathbf r(t)=\langle t^2,1-t,4t\rangle$
$\implies\mathbf r'(t)=\langle 2t,-1,4\rangle$

$\dfrac{\mathrm d(\mathbf r(t)\cdot\mathbf a(t))}{\mathrm dt}\bigg|_{t=5}=\mathbf r'(5)\cdot\mathbf a(5)+\mathbf r(5)\cdot\mathbf a'(5)$
$=\langle10,-1,4\rangle\cdot\langle-4,4,-5\rangle+\langle25,-4,20\rangle\cdot\langle-5,9,3\rangle$
$=(-40-4-20)+(-125-36+60)$
$=-165$
