Jacob consumes an energy drink that contains caffeine. After consuming the energy drink, the amount of caffeine in Jacob's body

sasho [114]

Answer: 0.87400mg of caffeine.

Step-by-step explanation:

You have

N(t)=N0(e^−rt)(1)

as a general Exponential decay equation where N0 is the amount at t=0, N(t) is the amount remaining at time t and r is the exponential decay constant. You're specifically given that after 10 hours, the decay factor is 0.2601, i.e.,

N(10)/N(0)=N0(e^−10r)/N0(e^0)= e^−10r=0.2601 . .(2)

Taking the last 2 parts of (2) to the power of 0.1t gives

e^−rt=0.2601^.1t . .(3)

This means that

N(t)=N0(e^−rt)=N0(0.2601^.1t). .(4)

Also,

N(2.56)N(1.56)=N0(0.2601.1(2.56))N0(0.2601.1(1.56))=0.2601.1(2.56−1.56)=0.2601^.1

= 0.87400mg of caffeine.

The x3 was supposed to be an exponent not 3x

mote1985 [20]

Answer:

The value of x is $2\sqrt[3]{2}$

Step-by-step explanation:

We are given $2+x^3=18$

We need to solve for x

First we subtract 2 both sides

$x^3=18-2=16$

Taking cube roots both sides to isolate x

$x=\sqrt[3]{16}$

Simplify the radical

$x=2\sqrt[3]{2}$

Thus, The value of x is $2\sqrt[3]{2}$

The perimeter of a triangle is 42 inches one side measures 18 inches the shortest side measures x inches the longest side measur

Oksana_A [137]

By writing an equation you can easily solve this:

18+ X + 4X - 1 = 42
•we need the answer to 4X-1

1. put the parts that include the X parameter in one side and the integer numbers in one side :
X + 4X = 25
5X= 25
X= 5

2. 4X-1 —> 4x5-1 = 19

The mean speed of vehicles along a stretch of highway is 56 mph with a standard deviation of 4 mph. You

Elenna [48]

The corresponding z score for speed of 62 mph, 47 mph, and 56 mph is 1.5, -2.25 and 0 respectively.

<h3>Z score</h3>

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

$z=\frac{x-\mu}{\sigma }$
