Need help in solving this problem. Section is under limits at infinity, horizontal asymptotes...
mojhsa [17]
 <span>(a) you can show the concentration by: 

amount of salt / amount of water 


amount of salt 

= 30g / L 

= [ 30 * 25g ] / [ 25L ] , 25L = 1 min 

= [ 30 * 25g ] / min 


amount of water 

= 5000 + 25t 


[ 30 * 25t ] / [ 5000 + 25t ] 

= [ 30 * 25t ] / 25*[ 200 + t ] 

= 30t / [ 200 + t ] yeah 


(b) 


lim t->∞ [ 30t / ( 200 + t ) ] 

= lim t->∞ [ ( (1 / t) * 30t ) / ( (1 / t) * ( 200 + t ) ) ] 

= lim t->∞ [ 30 / ( (200 / t) + 1 ) ] 

= 30 / ( (200 / ∞) + 1 ) 

= 30 / 1 

= 30

Lines ℓ and m are intersected by transversal t. ℓ ∥ m. Lines l and m are horizontal with l above m and intersected by transveral
artcher [175]

Answer:

<5 = 105 degrees

Step-by-step explanation:

From the description given, since line l is parallel to m then <4 is alternate to <5 and two alternate angles are equal, if thst is the case

<4 = <5 (alternate angle)

Since <4 = 105 degrees, hence m<5 = 105 degrees

Point C has the coordinates (–1, 4) and point D has the coordinates (2, 0). What is the distance between points C and D?
Luba_88 [7]

We conclude that the distance between points C and D is 5 units.

<h3>How to find the distance between the two points?</h3>

Remember that if we have two points (x₁, y₁) and (x₂, y₂), the distance between these points is:

d = √( (x₂ - x₁)^2 + (y₂ -  y₁)^2)

In this case, we know that:

Point C has the coordinates (-1, 4)

Point D has the coordinates (2, 0)

Then the distance between these two points is:

d = √( (-1 - 2)^2 + (0 - 4)^2) = √25 = 5

We conclude that the distance between points C and D is 5 units.

Solve and graph the absolute value inequality: |2x + 4| &gt; 8​
neonofarm [45]

Answer:

C

Step-by-step explanation:

To get rid of the absolute value bars you have to get two different equations which would be 2x+4>-8 AND 2x+4>8. Pay attention to the signs, if there is greater than or equal to then it would have a line underneath the sign, which neither of the equations should have since you haven't moved a negative. solve normally and you'll get -6 blank circle and 2 blank circle.
