Answer:

Your answer is B

Step-by-step explanation:

There are 3 kids ages 9-10, so that's the first 3.

There are 10 kids ages 10-11, so that's the second 10.

There are 6 kids ages 11-12, so that's the third 6.

add those kids up and you get 19

\frac{x {}^{ - 1}y {}^{ - 2}  }{z {}^{ - 3} }

if the upper number got power of negative it will go down and the down will go up

So that,

\frac{z {}^{3} }{x {}^{1} {y}^{2}  }

power of 1 can no need to write

Find an autonomous differential equation with all of the following properties:
tresset_1 [31]

Answer:

dy/dt = y ( 3 - y )

Step-by-step explanation:

Given data:

Determine an autonomous differential equation with the following properties

y = 0 and Y = 3

y' > 0 for  0 < y < 3

y' < 0 for  -∞ < y < 0  and  3 < y < ∞

considering an autonomous differential equation

dy/dt = y ( 3 - y )

y = 0 and 3 represents equilibrium solutions

if 0 < y < 3  then y ( 3 - y ) > 0  for   0 < y < 3

hence : dy / dt = y' > 0  for 0 < y < 3

y ( 3 - y ) <  0  for -∞ < y < 0 and  3 < y < ∞

hence : dy / dt = y' < 0  for  -∞ < y < 0  and  3 < y < ∞

this shows that the autonomous differential equation satisfies every condition hence the autonomous differential equation is :

dy/dt = y ( 3 - y )

Emma has 56 37⁄40 bags of dog food to feed all of the dogs at the animal shelter. The dogs each eat 81⁄4 bags of food per week.
deff fn [24]

\text{Answer: Number of weeks }=56

Explanation:

Since we have given that

\text{Number of bags of dog food to feed all of the dogs at the animal shelter} =56\frac{37}{40}\text{Number of bags of food per week eaten by dogs }= 8\frac{1}{4}

So,

\text{Number of weeks worth of dog food Emma have } =\frac{56\frac{37}{40}}{8\frac{1}{4}}

\text{Number of weeks worth of dog food Emma have }=\frac{2240\times 4}{40\times 4}\\\text{Number of weeks worth of dog food Emma have }=\frac{2240}{40}\\\text{Number of weeks worth of dog food Emma have }=56

∴ \text{Number of weeks worth of dog food Emma have}=56
