Answer:

Step-by-step explanation:

To add efficiently, you would need to have a common denominator. in this case the least common denominator (LCD) would be 35. 1/7 = 5/35 and 2/5 = 14/35

add the numerators together to get your answer:

19/35

Answer:

19/35

Step-by-step explanation:

make the denominator 35

so 1/7 times 5/5= 5/35

2/5 times 7/7= 14/35

14/35 plus 5/35= 19/35

Evaluate s(t)=∫t−[infinity]||r′(u)||du for the bernoulli spiral r(t)=⟨etcos(8t),etsin(8t)⟩. It is convenient to take −[infinity]

sveta [45]

$\vec r(t)=\langle e^t\cos8t,e^t\sin8t\rangle$

$\|\vec r'(t)\|=\sqrt{(e^t(\cos8t-8\sin8t))^2+(e^t(\sin8t+8\cos8t))^2}=e^t\sqrt{(\cos8t-8\sin8t)^2+(\sin8t+8\cos8t)^2}$

$\implies\|\vec r'(t)\|=e^t\sqrt{65}$

Then

$s(t)=\displaystyle\sqrt{65}\int_{-\infty}^te^u\,\mathrm du=\sqrt{65}e^t$

Solve 6n + 10 < 4n + 16

BartSMP [9]

Answer:

n < 3

Step-by-step explanation:

6n + 10 < 4n + 16

( Minus 4n from both sides to isolate + 16 )

2n + 10 < 16

( Minus 10 from both sides to isolate 2n )

2n < 6

( Divide both sides by 2 to isolate n )

n < 3
