Answer:

-1

Step-by-step explanation:

f(x) =2/3x -5

Let x = 6

f(6) = 2/3 (6) - 5

Multiply first

f(6) = 12/3 -5

= 4-5

= -1

il63 [147K]

Answer:

there are three different types of answers to this and all of them have to do with the perspective of pi

1) if you don't want to see the decimals and you want to leave pi alone your answer would be this

3pi

2) if you want to solve for pi it would be

9.43 respectively

3) if you want pi to just be narrowed down to 3 digits 3.14 your answer would be

9.42

Step-by-step explanation:

formula

C=2*pi*R

plug in

2*pi*1.5

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 $r = 0.03$

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

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

$A(t) = 109(0.97)^t$

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.
