What is diffusion concentration gradient

1 answer:

8 0

The concentration gradient represents the concept that, just as a ball rolls down a slope, during diffusion molecules move down the concentration gradient. Higher concentration gradients will result in higher rates of diffusion. As the molecules move the gradient evens out until equilibrium is reached.

Write an equation that represents the line passing through the point -3, -1 with a slope of 4

Alex17521 [72]

Answer:

Equation that represents the line passing through the point -3, -1 with a slope of 4 is

$y= 4x+11$

Step-by-step explanation:

Equation of line in point slope form is

$y-y_1=m(x-x_1)$ -------(1)

Here

$m=4 \ \ \ and \ \ \ (x_1, y_1) = (-3, -1)$

Substituting values in equation (1)

$y+1=4(x+3)\\ y= 4x+11$

What is 1 5/8 divided by 5 1/7

weeeeeb [17]

Answer: 91/288

Step-by-step explanation: To divide mixed numbers, first write the mixed numbers as improper fractions.

We can do this by multiplying the denominator by the whole number and then adding the numerator. Then, we put our new numerator over our old denominator.

So here, we can write 1 and 5/8 as the improper fraction 13/8 and we can write 5 and 1/7 as the improper fraction 36/7.

So here, we have 13/8 ÷ 36/7.

Dividing by a fraction is the same as multiplying by the reciprocal of that fraction.

So here, 13/8 ÷ 36/7 is the same as 13/8 × 7/36.

So now we are simply multiplying fractions and we do this by multiplying across the numerators and multiply across the denominators.

$\frac{13}{8} x \frac{7}{36} = \frac{91}{288}$

So now we have 91/288 which is in lowest terms.

This means that 1 and 5/8 divided by 5 and 1/7 is 91/288.

What is the equation of the line that passes through the point (-1, -7) and has a<br> slope of 2?

o-na [289]

Answer:

(a,b)------>(-1,-7)let

now

m(x-a)=(y-b)

2(x+1)=(y+7)(where m=slope

2x+2=y+7

2x-y=7-2

2x-y=5 is a required equation.
