An average American child aged 0-2 years old has about 915 minutes of screen time in 5 days. 6 times the difference between a ch

ild aged 0-2 years (915) and a child aged 3-5 years (X) is the same as the sum of 100 and a child aged 3-5 years (X). How much screen time does an average child (x) have?​

Answer:

For children ages 2 to 5, limit screen time to one hour a day of high-quality programming. As your child grows, a one-size-fits-all approach doesn't work as well. You'll need to decide how much media to let your child use each day and what's appropriate.

Step-by-step explanation:

For kids aged 2 to 5, screen time should be limited to 1 hour per day, and parents should watch the programs with their child. Also, parents should have times when screens are turned off, and bedrooms should be media-free.

To solve problem 1 what you need to do is figure out how many miles the girls have walked so far and then subtract that from the total distance they must complete.

3/4-(3/10+1/4)

Step 1:Change the denominators so that way they are all the same

3/4=15/20
3/10=6/20              15/20-(6/20+5/20)
1/4=5/20

Step 2: Begin solving the problem

6/20+5/20=11/20
15/20-11/20=4/20

Step 3: Simplify your answer

4/20=1/5

Step 4 (is optional): Write your answer in a complete statement

The three girls walk 1/5mile together to school

Answer: A

I hope this is correct and if not I apologize for giving false information.

When a factor x − k is raised to an odd power, the graph crosses the x-axis at x = k.
oksian1 [2.3K]

Answer:

The graph of g(x) = (x - 1) (x + 4)^3(x +5)^2 crosses the x-axis at (1,0) and (-4, 0). It touches the x-axis at (-5, 0).

Step-by-step explanation:

g(x):

g(x) = (x - 1) (x - (-4))^3(x - (-5)^2.

There are three factors:

  • (x - 1), where k = 1,
  • (x - (-4)), where k = -4, and
  • (x - (-5)), where k = -5.

The first and second factors are raised to odd powers. The graph will cross the x-axis at all these two points:

  • (1, 0) as a result of the factor (x - 1),
  • (-4, 0) as a result of the factor (x - (-4)).

The third factor is raised to an even power. The graph will touch the x-axis at that point.

  • (-5, 0) as a result of the factor (x - (-5)).

Consider the growth of a population p(t). It starts out with p(0)=A. Suppose the growth is unchecked, and hence p′=kp for some c
gayaneshka [121]

Answer:

p(t) = Ae^{\frac{kt^2}{2}}

Step-by-step explanation:

We are given the following information in the question:

The growth of population is given by the function p(t).

p(0)=A where A is a constant.

p' = kp

where k is a constant.

Solving the given differential equation, we have,

p' = kp\\\\\displaystyle\frac{dp}{dt} = kp\\\\\frac{dp}{p} = kt~ dt\\\\\text{Integrating both sides}\\\\\int \frac{dp}{p} = \int kt~ dt\\\\\log p = \frac{kt^2}{2} + C\\\\\text{where C is the integration constant}\\\\\text{Putting t = 0}\\\\\log p_0 = C\\\\\log p = \frac{kt^2}{2} + \log p_0\\\\\log p - \log A = \frac{kt^2}{2}\\\\\log \frac{p}{A} = \frac{kt^2}{2}\\\\p(t) = Ae^{\frac{kt^2}{2}}

Simplify to a simplified fraction <br><br> 1/2+1/3+1/4+1/5+1/6+1/7+1/8+1/9+1/10
Reptile [31]

Answer:

Step-by-step explanation:

Hello

Simplify to a simplified fraction

1/2+1/3+1/4+1/5+1/6+1/7+1/8+1/9+1/10

= 5/10 + 2/6 + 2/8 + 2/10 + 1/6 + 1/7 + 1/8 + 1/9 + 1/10

= 8/10 + 3/6 + 3/8 + 1/7 + 1/9

= 24/30 + 15/30 + 21/56 + 8/56 + 1/9

= 39/30 + 29/56 + 1/9

= 117/90 + 29/56 + 10/90

= 127/90 + 29/56

= 3556/2520 + 1305/2520

= 4861/2520
