A population numbers 508 organisms initially and increases by 6.2% each year.
IceJOKER [234]

To find the population after t number of years, multiply the starting population by 1 plus the percent increase raised to the number of years.

The equation would be: P = 508(1.062)^t

Where does the line through (1, 0, 1) and (4, −3, 3) intersect the plane x + y + z = 6?
Irina-Kira [14]

Parametrically for real t the line is


(x,y,z) = (1-t)(1,0,1) + t(4,-3,3)


(x,y,z) = (1,0,1) + t(4-1,-3-0,3-1)


(x,y,z) = (1,0,1) + t(3,-3,2)


That's three equations; we substitute into


x+y+z=6


(1+3t)+(0-3t) + ( 1+2t)=6


2t=4


t=2


(x,y,z) = (1,0,1) + 2(3,-3,2) = (7,-6,5)


The intersection is a single point (7,-6,5).

WILL GIVE BRAINLY: VOLUME
Brilliant_brown [7]

The formula for volume is

V = Lenght x Width X Height

In your diagram, we have all 3 of these.

Length = 25 cm

Width = 12 cm

Height = 14 cm

To make it easier let's just convert all these to meters.

Length = 0.25 m

Width = 0.12 m

Height = 0.14 m

V = (0.25)(0.12)(0.14)

V = 0.0042 cubic meters

First of all, you have to understand g<span> is a square-root function. 

</span>Square-root functions are continuous across their entire domain, and their domain is all real x-<span>values for which the expression within the square-root is non-negative. 
</span>
In other words, for any square-root function q and any input c in the domain of q (except for its endpoint), we know that this equality holds:  lim \ q(x)=q(c) 

Let's take \sqrt{x} <span>as an example. 
</span>
The domain of \sqrt x is all real numbers such that x \geq 0.  Since x=0  is the endpoint of the domain, the two-sided limit at that point doesn't exist (you can't approach 0 <span>from the left). 
</span>
<span>However, continuity at an endpoint only demands that the one-sided limit is equal to the function's value: 
</span>
lim \  \sqrt{x} =  \sqrt{0} =0 

In conclusion, the equality lim \ q(x)=q(c) holds for any square-root function q and any real number c  in the domain of q e<span>xcept for its endpoint, where the two-sided limit should be replaced with a one-sided limit. </span>

The input x=-3,  is within the domain of g<span>. 
</span>
Therefore, in order to find  lim \ g(x)  we can simply evaluate g at x-3<span>. 
</span>
g(x) 

\sqrt{7x+22} 

\sqrt{7(-3)+22}
