Answer:

f(3)=-1

Step-by-step explanation:

Given equation is:-

f(x)=-\frac{2}{3}x+1

To find f(3) we need to substitute 3 in place of x in the above equation i.e. f(x)=-\frac{2}{3} x+1

After substituting 3 in place of x we get,

f(3)=-\frac{2}{3}\times (3)+1

f(3)=-2+1

f(3)=-1

Therefore for function f(x)=-\frac{2}{3}x+1,\   f(3)=-1

The current in a simple electrical circuit is inversely proportional to the resistance. The current is 80 amps when the resistan
Oksana_A [137]
I =  / r            where I = current and r = resistance

80 = k / 50 so
k = 400

so we have I = 400/r

when r = 40  
I = 400/40 = 10 amps

Everyday Isabel swims 10-20 laps in a 50 meter pool. The amount of time she spends swimming is represented by the function f(x)
Inessa [10]

Given :

Everyday Isabel swims 10-20 laps in a 50 meter pool.

The amount of time she spends swimming is represented by the function f(x) = 3x .

To Find :

The speed of Isabel.

Solution :

Distance travelled in x laps is, D = 50x .

It is given that time taken is, t = 3x .

So, speed of Isabel is given as :

Speed=\dfrac{Distance}{Time}\\\\Speed = \dfrac{50x}{3x}\\\\Speed = \dfrac{50}{3}=16.67 \ m/s

Hence, this is the required solution.
