Answer:

See Explanation;

Step-by-step explanation:

The given vectors are;

$v_1=\:\:$ and $v_2=\:\:$

a) To add or subtract two vectors, we add or subtract their corresponding components

$v_1+v_2=\:\:+\:\:$

$v_1+v_2=\:\:$

$v_1-v_2=\:\:-\:\:$

$v_1-v_2=\:\:$

$v_2-v_1=\:\:-\:\:$

$v_2-v_1=\:\:$

Using proportions, the expected number of adults in Palm City whose main source of news is the internet or newspaper is of 19,413.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

From the table, the proportion of adults in Palm City whose main source of news is the internet or newspaper is found as follows:

p = (62 + 88)/(62 + 88 + 128 +24 + 38) = 0.4412.

Hence, out of 44,000 adults, the expected number is found as follows:

0.4412 x 44000 = 19,413.

Answer:

Linear second-order differential equation F(x, y, y′, y″) = 0

y¹¹( -3 x⁴ )+ y¹12 x³ - 12 x² y= 0

Step-by-step explanation:

Step(i):-

Given differential equation

y = c₁x + c₂x⁴ ...(i)

Differentiating equation (i) with respective to 'x', we get

y¹ = c₁(1) + c₂ ( 4 x³ ) ...(ii)

Differentiating equation (ii) with respective to 'x', we get

y¹¹ = c₂ ( 12 x² )

$C_{2} = \frac{y^{11} }{12 x^{2} }$ ...(a)

Step(ii):-

Substitute (a) in equation (ii)

$y^{l} = C_{1} + (\frac{y^{ll} }{12x^{2} } ) (4 x^{3} )$

$C_{1} = y^{l} - (\frac{y^{ll} }{12 x^{2} } ) (4 x^{3} )$ ...(b)

$C_{2} = \frac{y^{11} }{12 x^{2} }$

Step(iii):-

$y = (y^{l} - (\frac{y^{ll} }{12 x^{2} } ) (4 x^{3} ) x + \frac{y^{ll} }{12 x^{2} } x^{4}$

12 x² y = (y¹12 x³ - 4 x⁴ y¹¹) + x⁴ y¹¹

x⁴ y¹¹ - 4 x⁴ y¹¹ + y¹12 x³ - 12 x² y= 0

y¹¹( -3 x⁴ )+ y¹12 x³ - 12 x² y= 0
