Answer:

5yz

Step-by-step explanation:

1st expression=10xyz

=5*2*x*y*z

2nd expression=15(y)2 (z)2

=5*3*y*y*z*z

therefore H.C.F=5yz

PLEASE HELP!!!!

Answer:

Mike is not right

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared

Let

z----> the scale factor

x----> surface area of the enlarged rectangular prism

y-----> surface area of the original rectangular prism

$z^{2}=\frac{x}{y}$

In this problem we have

$z=2$

substitute

$2^{2}=\frac{x}{y}$

$4=\frac{x}{y}$

$x=4y$

The surface area of the enlarged rectangular prism is 4 times the surface area of the original rectangular prism

therefore

Mike is not right

Verify with an example

we have a rectangular prism

$L=5\ m$

$W=2\ m$

$H=3\ m$

The surface area of the prism is equal to

$SA=2(LW)+(2L+2W)H$

substitute the values

$SA=2*(5*2)+(2*5+2*2)*3=62\ m^{2}$

If he doubles each dimension of any rectangular prism

then

the new dimensions will be

$L=5*2=10\ m$

$W=2*2=4\ m$

$H=3*2=6\ m$

The new surface area will be

$SA=2*(10*4)+(2*10+2*4)*6=248\ m^{2}$

$248/62=4$

therefore

The surface area of the enlarged rectangular prism is 4 times the surface area of the original rectangular prism

Based on census data, the population of Freedonia is modeled by the function P ( t ) = 325 t^2 + 28547 people, where t represent

navik [9.2K]

Answer:

dP/dt = 650t = 650(2 ) = 1,300 people/year

The rate of increasing of population at the end of the year 1992 is 1,300 people/year

Step-by-step explanation:

Given;

Population function as;

P(t) =325 t^2 + 28547

The rate of change of the population dP/dt at any given time can be given as;

Rate = change in population/change in time = dP/dt

dP/dt = 2×325t = 650t

Therefore, after 1992;

t = 1992-1990 = 2years

dP/dt = 650t = 650(2 ) = 1,300 people/year

The rate of increasing of population at the end of the year 1992 is 1,300 people/year
