What is the surface area of this prism? A. 120 cm2 B. 122 cm2 C. 240 cm2 D. 184 cm2
Aneli [31]
Here is how to get the Surface Area of a triangular prism.
First you must find their areas first then multiply it by 2 (because it has 2 faces) except for the base, since it has a triangular base.
A = bxh/2                           A = 15 m x 30 m         A = 30 m x 18 m
   = (18 m x 12 m )/2             =  450 m^2                  = 540 m^2 
   = 216 m ^2/2
   = 108 m^2
Add all the faces:
SA = 2 (108 m^2) + 2 (540 m^2 ) + <span> 450 m^2     
     = 216 m^2 +1080 m^2 + </span><span>450 m^2  
     = 1,746 m^2
The answer is not found in your choices. The attached picture is also showing m (meter) as the unit used not cm.....so I guess you got the wrong choices.

In​ 2012, the population of a city was 6.57 million. The exponential growth rate was 2.87​% per year. ​a) Find the exponential g
icang [17]

Answer:

a) P(t) = 6.57e ^{0.0287t}

b) P(6) = 7,805\ million

c) t = 14.64\ years

d) t = 24.15\ years

Step-by-step explanation:

a) The function of exponential growth for a population has the following formula:

P(t) = p_0e ^{rt}

In this equation:

p_0 is the initial population

r is the growth rate

t is the time in years

In this problem we know that

r = 2.87\% = 0.0287

p_0= 6.57 million in the year 2012.

So the equation is:

P(t) = 6.57e ^{0.0287t}

Where t = 0 represents the year 2012

b) If t = 0 in 2012, then in 2018 t = 6

The population in 2018 is:

P(t = 6) = 6.57e ^{0.0287(6)}\\\\P(6) = 7,805\ million

c) To know when the population is equal to 10 million we must equal P(t) to 10 and solve for t.

P(t) = 10 = 6.57e ^{0.0287t}\\\\\frac{10}{6.57} = e ^{0.0287t}\\\\ln(\frac{10}{6.57}) = 0.0287t\\\\t = \frac{ln(\frac{10}{6.57})}{0.0287}

t = 14.64\ years

d) The function is doubled when P(t) = 2p_0

P(t) = 2(6.57) = 13.14 = 6.57e ^{0.0287t}

We solve for t.

\frac{13.14}{6.57} = e ^{0.0287t}\\\\ln(\frac{13.14}{6.57}) = 0.0287t\\\\t = \frac{ln(\frac{13.14}{6.57})}{0.0287})

t = 24.15\ years
