Given that t<span>he height of a cylinder is 9.5 centimeters and that the diameter of this cylinder is 1.5 centimeters longer than the height, thus, the diameter of the cylinder is 9.5 + 1.5 = 11 cm and the radius of the cylinder is diameter / 2 = 11 / 2 = 5.5 cm.

The volume of the cylinder is given by

</span>V=\pi r^2h \\  \\ =\pi(5.5)^2(9.5) \\  \\ =\pi(30.25)(9.5) \\  \\ =287.375\pi\approx902.8cm^3<span>

Two students were asked to find the value of a $1000 item after 3 years. The item was depreciating (losing value) at a rate of 4
Yuki888 [10]

Answer:

<em>Student 2 is incorrect because he didn't use the formula properly</em>

Step-by-step explanation:

The exponential function is often used to model natural growing or 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 initial value of the item is Co=$1000, the rate of decay is r=40%=0.4, and the time is t=3 years.

Substituting into the formula:

C(3)=\$1000\cdot(1-0.4)^3

C(3)=\$1000\cdot0.6^3

C(3)=$216

Student 2 is incorrect because he didn't use the formula properly

1. Consider f(x) = 3x - 5
Rzqust [24]

Answer:

3

Step-by-step explanation:

Here we have the function

f(x)=3x-5

We want to find the following ratio:

\frac{f(x+h)-f(x)}{h}

Note that the limit of this for h\rightarrow 0 is equivalent to the derivative of the function.

Here we have:

f(x+h)=3(x+h)-5=3x+3h-5

And

f(x)=3x-5

Therefore we have

f(x+h)-f(x)=3x+3h-5-(3x-5)=3h

And therefore,

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