Answer:

-1

Step-by-step explanation:

f(x)  =2/3x -5

Let x = 6

Identify the factors of x2 + 16y2.
BabaBlast [244]

The way to find the factores is by seeking the polonomial's roots, or zeros!

To find the roots, we set the polinomial equation to zero:

x^2+16y^2=0

Then we solve this equation:

x^2=-16y^2

This is only true, if x=y=0.

Find rhe volume of a cylinder with a diameter of 10 inches and a height of 20 inches
IrinaK [193]
Since the diameter of the cylinder is 10, its radius is half that, or 5, thus

\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h~~
\begin{cases}
r=radius\\
h=height\\
-----\\
r=5\\
h=20
\end{cases}\implies V=\pi (5)^2(20)

Currently, the number of people entering a shopping mall is 109. It is estimated that the number of people entering the shopping
seropon [69]

Answer:

96 people.

Step-by-step explanation:

Exponential equation for a decreasing amount:

The exponential equation for a decreasing amount is given by:

A(t) = A(0)(1-r)^t

In which A(0) is the initial rate and r is the decay rate, as a decimal.

Currently, the number of people entering a shopping mall is 109.

This means that A(0) = 109

It is estimated that the number of people entering the shopping mall will decrease by 3% each hour.

This means that r = 0.03

So

A(t) = A(0)(1-r)^t

A(t) = 109(1-0.03)^t

A(t) = 109(0.97)^t

Find the total number of people entering the shopping mall at the end of 4 hours.

This is A(4). So

A(4) = 109(0.97)^4 = 96.49

Rounding to the nearest whole number, 96 people.
