Answer:

The estimated populations in the years 2013 and 2020 are 320.262 and 343.365 respectively.

Step-by-step explanation:

The resident populations P (in millions) of the united states from 1995 through 2010 can be modeled by the exponential function

p(t)=254.75(1.01)^t

Where t is the time in years,with t = 5 corresponding to 1995.

It means the initial year is 1990, ( 1995 - 5 = 1990).

Using this model we need to estimate the populations in the years 2013 and 2020.

2013 - 1990 = 23

Substitute t=23 in the given function.

p(23)=254.75(1.01)^{23}\approx 320.262

2020 - 1990 = 30

Substitute t=30 in the given function.

p(30)=254.75(1.01)^{30}\approx 343.365

Therefore, the estimated populations in the years 2013 and 2020 are 320.262 and 343.365 respectively.

A metalworker has a metal alloy that is 15​% copper and another alloy that is 60​% copper. How many kilograms of each alloy shou
coldgirl [10]

18 kg of 15% copper and 72 kg of 60% copper should be combined by the metalworker to create 90 kg of 51% copper alloy.

<u>Step-by-step explanation:</u>

Let x = kg of 15% copper alloy

Let y = kg of 60% copper alloy

Since we need to create 90 kg of alloy we know:

x + y = 90

51% of 90 kg = 45.9 kg of copper

So we're interested in creating 45.9 kg of copper

We need some amount of 15% copper and some amount of 60% copper to create 45.9 kg of copper:

0.15x + 0.60y = 45.9

but

x + y = 90

x= 90 - y

substituting that value in for x

0.15(90 - y) + 0.60y = 45.9

13.5 - 0.15y + 0.60y = 45.9

0.45y = 32.4

y = 72

Substituting this y value to solve for x gives:

x + y = 90

x= 90-72

x=18

Therefore, in order to create 90kg of 51% alloy, we'd need 18 kg of 15% copper and 72 kg of 60% copper.

a trapezoide has an area of 150 square meters. If the bases are 14 meters and 16 meters, what is the height of the trapezoid​
SIZIF [17.4K]

Answer:

h = 10 m

Step-by-step explanation:

The formula for area of a trapezoid is  

A = (1/2)(B + b)h   where B is the bottom base, b is the top base, and h is the height.  

We are given B = 16, b = 14, and A = 15, plug those values in and simplify

150 = (1/2)(16 + 14)(h)

      150 = (1/2)(30)(h)

          150 = (15)h             (half of 30 is 15)

                10 m =  h       (divide both sides by 15 to isolate h)
