Find the period of the function
Ostrovityanka [42]

Answer:

6π

Step-by-step explanation:

The period indicates after which time the sine wave repeats.

You divide 2π by the factor in front of your function variable. This is 1/3 for your function.

So 2π/(1/3) = 6π

Two cars are traveling on two different routes, one 43 miles longer than the other. The car traveling on the longer route travel
dedylja [7]

Answer:

Step-by-step explanation:

Let "s" be the the speed of the car taking   the shorter route in \frac{mi}{hr},

Let "s-2"  the speed of the cat taking the   longer route in \frac{mi}{hr},

Let "d" be the distance of the shorter route in miles and "d+43" be the distance of the longer route in miles.

Now, Equation for car taking the shorter route is given as:

d=s{\times}5                      (1)

and Equation for car taking the longer route is given as:

d+43=(s-2){\times}6               (2)

Now, substitute equation (1) in (2), we get

5s+43=6s-12

⇒43+12=s

⇒s=55

Therefore, equation (1) becomes,

d=5s=5(55)=275

Thus, the shorter route is =275 miles and the longer route is =d+43=275+43= 318 miles.

Help Me! I suck with vectors.<br> Look at the attached pictures for the problem.
Westkost [7]

Multiplying a vector x by a constant k gives you a new vector whose components are the same as x, but scaled by k:

x=\langle x_1,x_2\rangle\implies x=\langle kx_1,kx_2\rangle

So we have

u=\langle5,-7\rangle\implies-6u=\langle-30,42\rangle

v=\langle-11,3\rangle\implies2v=\langle-22,6\rangle

Vector addition is just a matter of adding the corresponding components together:

x=\langle x_1,x_2\rangle,y=\langle y_1,y_2\rangle\implies x+y=\langle x_1+y_1,x_2+y_2\rangle

Then

2v-6u=\langle-22,6\rangle+\langle-30,42\rangle=\langle-22-30,6+42\rangle

\implies\boxed{2v-6u=\langle-52,48\rangle}

\|x\| denotes the norm/magnitude of the vector x:

x=\langle x_1,x_2\rangle\implies\|x\|=\sqrt{{x_1}^2+{x_2}^2}

We have

\|2v-6u\|=\sqrt{(-52)^2+48^2}=4\sqrt{313}

\implies\boxed{\|2v-6u\|\approx70.77}
