Answer:

4.13Hz

Explanation:

f1 = 1/t1 = 1/0.022 = 45.45 Hz

f2 = 1/t2 = 1/0.0242= 41.32 Hz

No. of beats

= 45.45- 41.32

~ 4.13Hz

The line models the cost of renting a bike. It costs ​$3 per hour plus a ​$4 deposit. Write an equation in​ slope-intercept form
skad [1K]

Answer:

y=($3/1h)x+$4, it costs $19 to rent the bike for 5 hours.

Explanation:

An equation in slope-intercept form is y=m*x+n. In this case y would be the cost of rent, while x is the time. We need to determine m and n.

At the very beginning, x=0h (h is hours), the cost of rent is the deposit, so we know that $4=m*0h+n=n. Then we know that the cost of rent must increase by $3 with each hour, which means that the slope is m=$3/1h. Another way of getting this value would be to think on a particular case: after 1 hour, the cost of rent should be the deposit plus an hour of rent, or $7, so it should happen that <em>$7</em>=m*<em>1h</em>+$4 (where the $4 we already know is the value of n, and the numbers in italics are the values for the particular case we are looking for), from where we get that m*1h=$3, so m=$3/1h (the same result as before).

Putting all together, we have y=($3/1h)x+$4, and for 5 hours we get y=($3/1h)(5h)+$4

Olegator [25]

Answer:

The cable used is a straight through cable.

Explanation:

The cable used here is a straight through cable, that is why it fails to establish the connection.

Cross-over cables are used to communicate over legacy switch. It is used to connect computing devices directly.

In a cross over cable, signal gets transmit from one end of the device to the other.

Anna35 [415]

Answer:

w = 0.886 rad / s

Explanation:

Angular and linear variables are related

       a = α r

where a is the linear acceleration, α the angular acceleration and r the radius of gyration

         α = a / r

the angular velocity we can find it

         w² = w₀² + 2 α θ

the initial angular velocity is zero, the angles to be horizontal is

    θ = π/ 2  rad

     

we substitute

          w = √ 2 a / r  θ

we calculate

          w = √ (2 3/12 π/2)

          w = 0.886 rad / s
