Gelneren [198K]

The total surface area of a cylinder is given by the formula

$\begin{gathered} A_{cylinder}=2circular\text{ area+curved surface area} \\ =2\pi r^2+2\pi rh \end{gathered}$

Given diameter, d=12meters, we will solve for radius

$\begin{gathered} \text{diameter,d}=2\times radius,r \\ d=2r \\ r=\frac{d}{2} \\ r=\frac{12m}{2} \\ r=6m \end{gathered}$

The height is given as 9meters

Substituting for r and h in the formula will give

$\begin{gathered} A_{cylinder}=2\pi r^2+2\pi rh \\ r=6m;h=9m;\pi=3.14 \\ A_{cylinder}=2\times3.14\times6^2+2\times3.14\times6\times9_{} \end{gathered}$ $\begin{gathered} A_{cylinder}=6.28\times36+6.28\times54 \\ =226.08+339.12 \\ =565.2m^2 \end{gathered}$

Hence the surface area of the cylinder is 565.2m²

Answer:

$\large \boxed{\textbf{30.54 yr}}$

Step-by-step explanation:

For species A,

$P =2000e^{0.05t}$

For species B,

$P =5000e^{0.02t}$

When their populations are equal,

$\begin{array}{rcl}2000e^{0.05t} & = & 5000e^{0.02t}\\e^{0.05t} & = & 2.5e^{0.02t}\\0.05t & = & \ln2.5 + 0.02t\\0.05t & = & 0.9163 + 0.02t\\0.03t & = & 0.9163\\t& = & \dfrac{0.9163}{0.03}\\\\& = & \mathbf{30.54}\\\end{array}\\\text{The populations of species A and B will be the same in $\large \boxed{\textbf{30.54 yr}}$}$

The diagram below shows the population of Species A overtaking that of Species B in about 30.5 yr.

Can you please show me the steps and solution to this problem?

ANEK [815]

M = - 7 - 3 / - 2 - 4
m = - 10 / - 6
m = 10/6
m = 5/3

y = 5/3x + c , (4,3)
3 = 5/3(4) + c
12 = 20 + 4c
4c = - 8
c = - 2
y = 5/3x - 2

i am a mathematics teacher. if anything to ask please pm me

What are the solutions to the system of equations? {−x+y=4y+12=x2+x

monitta

Answer:Since -2 can not equal 0, there is no solution. The lines are parallel. It is an inconsistent system.

Step-by-step explanation:

The first step in solving a system of equations by substitution is solving one of the equations for one of the variables

x - y = 0 Equation 1

x - y + y = 0 +y Add y to each side

x = y Simplify

After solving an equation for one of the variables, substitute that value into the other equation. In this problem, I can substitute y for x.

x - y - 2 = 0 Equation 2

y - y - 2 = 0 Substitute the value of x from equation 1

0 - 2 = 0 Inverse Property of addition

-2 = 0 Identity Property of addition
