Between the ages 2 and 20, the weight W of an American boy is logistic function of his age. For boys at the 50 percentile, the differential equation for W can be approximated by 4W = 0.0008W (216 - W), where W is measured in pounds and t is measured in years beyond the age of 2. Express W as a function of t subject to the initial condition W(0) = 24

What is the solution of the following systems of equations? y = 1/2x
y = -x -3
Answer:
x = -2, y = -1
Step-by-step explanation:
System of Equations
Solve the system:
y = 1/2x
y = -x - 3
Multiplying the first equation by 2:
2y = x
Substituting x in the second equation:
y = -2y - 3
Adding 2y:
3y = -3
y = -3/3
y = -1
And x = 2*(-1) = -2
Solution: x = -2, y = -1

Which sequence explains a geometric method of determining 3-17i/2+2i ?
Answer:
pretty sure its B
Step-by-step explanation:
plot 3 - 17i scale by [tex]\sqrt\frac{2}{4}[/tex]. Rotate 45 ° clockwise
The series explains a geometric procedure for calculating plots 3 - 17i, scale 2√2, and rotation 45 clockwise.
What is a geometric series?A geometric series is an equation that results from adding all the terms in a geometric sequence.
As per the data given in the question,
(3 - 17i)/(2 + 2i)
Now, use the method of rationalization,
(3 - 17i)/(2 + 2i) × (2 - 2i)/(2 - 2i)
(3 - 17i)/8 × (2 - 2i)
= (6 - 6i - 34i - 34)/8
= (-28 - 40i)/8
It will rotate 45° clockwise.

Calculating the slope is simple
First, pick two points on the line
Next, see how far the second point is from the first point in the y direction only (the rise)

What is the ratio of oranges to apples? Write it as a fraction?
We could simply the ratio to?
Answer:
See below.
Step-by-step explanation:
3.)
There are 4 oranges and 6 apples so the fraction would be 4/6 which we can reduce to 2/3.
a.) As we stated beforehand, the fraction was 2/3. That means for every 2 oranges, there are 3 apples.
b.) We did this already. 4/6 was reduced to 2/3.

Need help with a few geometry questions !?!?
Answer:
1. ACB, CDB and ADC are all similar to eachother.
2. 10
3. CD=8, AD=10.666667, AC=13.33333
4. X=2.4
5. X=√10
6. X=√15
Step-by-step explanation:
1. To prove triangles are similar, prove they share at least two angles.
Triangle ACB is similar to triangle CDB because they both share a 90° angle and ∠B.
Triangle ACB is similar to triangle ADC because they both share a 90° angle and ∠A.
Since ACB is similar to both CDB and ADC respectively, CDB is similar to ADC.
2. Use similar triangles to find AB
ACB is similar to CDB
AB/CB=CB/DB
AB/10=10/6
AB=100/6=16.666667
Geometric mean: √(16.66667*6)=10
3.
Find CD using Pythagorus:
10²=6²+CD²
CD²=100-36
CD=√64=8
Use similar triangle ratios to find AD:
CDB is similar to ADC.
CD/DB=AD/DC
8/6=AD/8
AD=8(8/6)=10.6666666667
Find AC using Pythagorus:
AC²=10.66666666667²+8²
AC=√177.7777777778
AC=13.333333333
4. √(40²+30²)=50
30/50=X/40
X=2.4
5. (√35)²=X²+5²
35=X²+25
X=√10
6. √((√10)²-(√6)²=√(10-6)=2
√6/2=X/√10
6/4=X²/10
X²=10(1.5)
X=√15
