Rearrange the equation so nnn is the independent variable. m+1=-2(n+6)m+1=−2(n+6)

lapo4ka [179]

Answer:

$m=-2n-13$

Step-by-step explanation:

The given equation is $m+1=-2(n+6)$

We want to rearrange this equation so that, n becomes the independent variable.

This means we must solve form, m which becomes the dependent variable.

We expand the parenthesis to get:

$m+1=-2n-12$

We now subtract 1 from both sides to obtain:

$m=-2n-12-1$

We simplify to obtain:

$m=-2n-13$

This can be rewritten as

$m(n)=-2n-13$

A scuba diver is swimming 28 feet below the water’s surface. The diver swims up slowly at a rate of 0.3 feet per second for 6 se

NISA [10]

Answer:

27.4 feet down deep

Step-by-step explanation:

28 feet down, swins up for 0.3 feet times 6 or 1.8 feet up

leaving a total of 26.2 under the sea and he swims back down at 0.3 feet times 4 or 1.2 feet down. and the new total is 26.2 + 1.2 which equals 27.4 feet down in the deep sea

A jogger is going around a circular track with a radius of 100 ft. Determine the

sweet-ann [11.9K]

Answer:

ω= 0.01 rad/s

Step-by-step explanation:

The given data is question is ,

r = 100ft .
t = 3 min = 180s.

Firstly let's find the linear speed. Which is

=> v = Circumference/time

=> v = 2πr/180s

=> v = 3.14 × 100ft ./ 90

=> v = 3.48 ft/s ≈ 1m/s

Now the angular speed and linear speed are related as follows ,

=> v = r $\omega$

=> $\omega$ = v/r

=> $\omega$ = 1/100

=> $\omega$ = 0.01 rad/s

<h3>Hence the angular speed is 0.01 rad/s.</h3>
