Answer:

a

Step-by-step explanation:

9(5x)=45x

9(2)=18

4(8)=32

4(-x)=-4x

45x-4x=41x

32+18=50

41x+50

The population P of a small town, measured in hundreds, is modeled by the inverse of the function P−1(t) = 10ln(50t − 1000), whe
AleksandrR [38]

Using the inverse function, it is found that the equation is:

P(t) = \frac{e^{0.1t}}{50} + 20

It's initial value is 20.

---------------------------

We want to find the inverse of:

y = P^{-1}(t) = 10\ln{50t - 1000}

To do this, we <u>exchange y and t, and isolate y.</u>

Then:

10\ln{50y - 1000} = t

\ln{50y - 1000} = \frac{t}{10}

e^{\ln{50y - 1000}} = e^{0.1t}

50y - 1000 = e^{0.1t}

50y = e^{0.1t} + 1000

y = \frac{e^{0.1t} + 1000}{50}

y = \frac{e^{0.1t}}{50} + \frac{1000}{50}

P(t) = \frac{e^{0.1t}}{50} + 20

It's initial value is:

P(0) = \frac{e^{0.1(0)}}{50} + 20 = 0.02 + 20 = 20.02

Rounding, 20.

Find the mass of the triangle with vertices (1; 0; 0), (0; 2; 0), (0; 1; 1) if the density function is given by (x; y; z)
Luda [366]

Answer:

=\frac{17}{3}

Step-by-step explanation:

Density of a function is \rho(x,y)=x^{2} +y^{2}

I have drawn the right angle triangle for visualization

equation for the line passing through (1,0) and (0,4) is

\frac{y}{4} =\frac{x-1}{-1}

y=4-4x

=$$\int_{0}^1\int_{0}^{4-4x} (x^{2}+y^{2})dydx$$

=$\int_{0}^{1}(x^{2}+\frac{y^{3} }{3})dx$  

=$\int_{0}^{1}(x^{2}(4-4x)+\frac{1}{3}(4-4x)^{3} )dx$

=$\int_{0}^{1}(\frac{-76}{3}x^{3} +68x^{2}-64x^{}+\frac{64}{3}  )dx$

==(\frac{-76}{3} \frac{x^{4} }{4})+\frac{68}{3}x^{3}-32x^{2}+\frac{64}{3}x^{})  

=\frac{17}{3}

What is the effect on the graph of the function f(x) =5x when f(x) is replaced with f(x) + 9?
Nimfa-mama [501]

Answer:

When we add 9 to the function we are shifting the function up 9 units.


Step-by-step explanation:

If it were added inside the function, it woulds shift it left or right.

But since it is outside the function, we will shift it up or down

When we add 9 to the function we are shifting the function up 9 units.
