Answer:

A. x+1= 4x+5

Step-by-step explanation:

To solve the set of equation we can use substitution method.

Here the given set of equations are

Equation A : $y=x+1$

Equation B : $y=4x+5$

Now in substitution method we substitute y in terms of x from

first equation in to 2nd equation.

In other words we can also say that we equate both equations

so we have

$y=x+1 = 4x+5$

or we can also say that

$x+1= 4x+5$

hence the correct option is option A

A town has a population of 6000 people in the year 2009 and is growing at a rate of 3% a year. Let t denote the time in years af

dusya [7]

Answer:

f(t) = 6000*1.03^t
k = 0.0295588

Step-by-step explanation:

The formula for exponential growth can be written a couple of different ways. One I prefer uses the problem numbers directly:

population = (initial population) × (growth factor)^t

Here, the initial population is 6000, and the growth factor is 1+3% = 1.03. Then the function can be written as ...

f(t) = 6000·1.03^t

Another way to write the function is using the form ...

f(t) = (initial population) × e^(kt)

where k is the natural logarithm of the growth factor. In this form, we have ...

k = ln(1.03)

k ≈ 0.0295588

so the function would be written ...

f(t) = 6000·e^(0.0295588t)

The volume of a cylinder can be expressed as V=πr2h, where r is the radius, and h is the height of the cylinder.

olga_2 [115]

<em>Note: You missed to add the answer choices, so I am solving the overall procedure to determine the radius of the cylinder so that you could easily figure out the right choice.</em>

Answer:

The radius of the cylinder:

$r\:=\:\sqrt{\frac{v}{\pi \:h}}$

Step-by-step explanation:

The volume of a cylinder is represented by the formula

V=πr²h

here

r is the radius

h is the height

The radius of the cylinder can be computed using the formula of the volume of a cylinder

V = πr²h

r² = V / πh

Taking square roots

$r\:=\:\sqrt{\frac{v}{\pi \:h}}$

Thus, the formula of the radius of the cylinder.

$r\:=\:\sqrt{\frac{v}{\pi \:h}}$

Therefore, the radius of the cylinder:

$r\:=\:\sqrt{\frac{v}{\pi \:h}}$
