Find 8% of 1900.

0.08 * 1900 = 152

So 152 customers run every day.

Answer:

<em>M(13)=14.3 gram</em>

Step-by-step explanation:

<u>Exponential Decay Function</u>

The exponential function is used to model natural decaying processes, where the change is proportional to the actual quantity.

An exponential decaying function is expressed as:

C(t)=C_o\cdot(1-r)^t

Where:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

The element has an initial mass of Mo=970 grams, the decaying rate is r=27.7% = 0.277 per minute.

The equation of the model is:

M(t)=M_o\cdot(1-r)^t

M(t)=970\cdot(1-0.277)^t

Operating:

M(t)=970\cdot 0.723^t

After t=13 minutes the remaining mass is:

M(13)=970\cdot 0.723^{13}

Calculating:

M(13)=14.3 gram

Step-by-step explanation:

let's take out the parenthesis

-z-11=y

Now put 11 on the other side

Let's take a look. A baker is using three cups of water for every eight ounces of water.

Let's think of a ratio!

8 * x = 96
x =  cups of flour.


Let's solve the equation.

96 divided by 8 equals 12.

The correct answer would be D - 12 cups of flour.

A physicist working in a large laboratory has found that light particles traveling in a particle accelerator
Tomtit [17]

The particle will reach 50 km/hr when x = 32.25 hours

Step-by-step explanation:

A physicist working in a large laboratory has found that light particles

traveling in a particle accelerator  increase velocity in a manner that

can be described by the linear function - 4 x + 3 y = 21, where

  • x is the time in hours
  • y is the velocity in kilometer per hour

We need to find when a certain particle will reach  50 km/h

∵ - 4 x + 3 y = 21 is a linear function

∵ x represents the time (number of hours)

∵ y represents the velocity in km/h

∵ The velocity of a particle will reach 50 km/h

- Substitute y by 50 in the function above

∴ - 4 x + 3(50) = 21

∴ - 4 x + 150 = 21

- Subtract 150 from both sides

∴ - 4 x = -129

- Divide both sides by -4

∴ x = 32.25 hours

The particle will reach 50 km/hr when x = 32.25 hours
