6 0

Answer:

Step-by-step explanation:

period = 2 $\pi$ / b where b is 8/5 for this question

period = 2 $\pi$ / 8/5

period = 5*2 $\pi$ /8

period = 10 $\pi$ / 8

period = 5 $\pi$ / 4

Solve for b.

andriy [413]

It's -18.

-1/6b=3

Multiply the reciprocal of -1/6 to both sides, this will get x by itself

(-6/1)*-1/6b=3*(-6/1)

b= -18/1
b= -18

A clock has a diameter of 16 cm. How long is the metal band around it?

kramer

Answer:

The length of metal band around the given clock is 50. 24 cm.

Step-by-step explanation:

Here, the diameter of given clock = 16 cm

Now, Diameter = 2 x Radius

So, Radius = D/2 = 16 cm/2 = 8 cm

⇒The radius of the clock = 8 cm

Now, The metal Band around it = The CIRCUMFERENCE of the watch

Circumference of the clock = 2 π r

= 2 x ( 3.14) x ( 8) = 50.24 cm

or, C = 50.24 cm

Hence, the length of metal band around the given clock is 50. 24 cm.

Find the value(s) of x where the tangent to the graph of y=e^5x is parallel to the

Alik [6]

Answer:

There are none.

Step-by-step explanation:

No calculus involved:

The line, in slope-intercept form, has equation $y=-10x+17$ , ie is always decreasing (easy to spot applying the definition)

Meanwhile, $y=e^{5x}$ is always increasing over its domain.

At no point the tangent will be decreasing.

Let's use calculus

We are to solve the equation $y'(x) = -10 \rightarrow 5e^{5x} = -10 \rightarrow e^{5x}=-2$ which has no real solutions.
