#9 You have to make the fraction a decimal, then multiply 11.8 by 6.5. This is because 11.8 is per hour.

#10 here is a hint, one quarter of an hour is 15 minutes. again change the fraction to a decimal

#11 just multiply the 2 numbers
1.4
×2.9
---------
126
+ 280
------------------

\begin{aligned} &y=2x +1 \\\\ &x-y=-3 \end{aligned} y=2x+1 x−y=−3 Is (2,5)(2,5)left parenthesis, 2, comma, 5, right

trapecia [35]

Answer:

Yes

Step-by-step explanation:

Given the system of equations

$\begin{aligned} &y=2x +1 \\\\ &x-y=-3 \end{aligned}$

We want to determine if (2,5) is a solution of the system.

We can do this by substitution of the given point into the equations and see if it holds.

Given (x,y)=(2,5), x=2, y=5

In the first equation

y=2x+1

5=2(2)+1

5=5

Therefore, the point (2,5) satisfies the first equation.

In the second equation

$x-y=2-5=-3$

Since our result (-3) is equal to the Right Hand Side, the point also satisfies the second equation.

Therefore, (2,5) is a solution of the system.

Von Bertalanffy's equation states that the rate of growth in length of an individual fish is proportional to the difference betw

tiny-mole [99]

Answer:

dT/dt = k(L-Lt)

Step-by-step explanation:

Let the rate of growth in length be dL/dt

The difference between the current length L and the asymptotic length Lt will be expressed as L-Lt

If the rate of growth in length of an individual fish is proportional to the difference between the current length L and the asymptotic length Lt, this is expressed as;

dT/dt ∝ L-Lt

dT/dt = k(L-Lt) where

k is the proportionality constant

Hence the differential equation that expresses this idea is written as;

dT/dt = k(L-Lt)
