The height of the object after 3 seconds is 73.5 meters

A model function is a way of describing a real-life system or situation using mathematical concepts and language

Since the equation for the height of the object is given by:

s(t) = -4.9t² + 19.6t + 58.8 and t is the t in seconds

Thus, in order to find the height of the object after 3 seconds, you need to substitute  t = 3 into the equation. That is:

s(t) = -4.9t² + 19.6t + 58.8

s(t) = -4.9×(3)² + 19.6(3) + 58.8

s(t) = 73.5 meters

Using percentage profit formula, the selling price must be $24.8

Profit percentage is calculated by dividing the net profit by the total revenue and multiplying it by 100. For example, if a business has a net profit of $50,000 and total revenue of $500,000, its profit percentage is 10%.

The initial cost of the desert can be calculated using the formula of percentage profit.

percentage profit = [(selling price - cost price) / cost price] * 100

87.5 / 100 = 24 - x / x

0.875 = 24 - x / x

0.875x = 24 - x

24 = 1.875x

x = 12.8

The cost price is 12.8

The profit will be = 24 - 12.8 = 11.2

The general solution of the differential equation is y(x) = (c1 + c2x)e^(-x) + (1/5)e^(-x)(sin(ex) - (cos(ex)/e^x))

To solve the differential equation y'' + 3y' + 2y = cos(ex) using variation of parameters, we first need to find a particular solution of the form yp = u(x)e^(rx), where u(x) is a function of x and r is a constant.

The characteristic equation of the homogeneous equation is r^2 + 3r + 2 = 0, which has roots r1 = -1, r2 = -2. Thus, the general solution of the homogeneous equation is yh = c1e^(-x) + c2e^(-2x).

To find a particular solution, we use the method of variation of parameters. Let yp = u(x)e^(-x), where u(x) is a function of x. Then, y'p = u'(x)e^(-x) - u(x)e^(-x) and y''p = u''(x)e^(-x) - 2u'(x)e^(-x) + u(x)e^(-x).

Substituting yp, y'p, and y''p into the original equation and simplifying, we get:

u''(x)e^(-x) - 2u'(x)e^(-x) + u(x)e^(-x) = cos(ex)

We can solve for u(x) by dividing both sides of the equation by e^(-x)

u''(x) - 2u'(x) + u(x) = cos(ex)e^x

Now we need to find W(x) = W(y1,y2) = e^(-x)e^(-2x) = e^(-3x)

Integrating W'(x) cos(ex)e^x dx = -(1/5)e^(-x)(sin(ex) - (cos(ex)/e^x))

Hence we get the  general solution of the differential equation is

y(x) = (c1 + c2x)e^(-x) + (1/5)e^(-x)(sin(ex) - (cos(ex)/e^x))

The formula to find a hypotenuse is a^2 + b^2 = c^2 (a squared plus b squared = c squared).

The hypotenuse is the diagonal leg (line WH).

The line WJ = 7, and the line JH = 6.  Let's make line WJ a, and line JH b.

7^2 + 6^2 = c^2.  When you square a number, you multiply that number by itself.  7x7 + 6x6 = c^2.  7x7 = 49 and 6x6 = 36.  Now you have 49 + 36 = c^2

49 + 36 = 85.  85 = c^2.  Square root both sides.  The square root of 85 = the square root of c^2 (c). c = 9.21954446.  If you have to round the hypotenuse to the nearest hundredth, then your answer is 9.22.  The answer for the length of the hypotenuse is 9.22

can they sit around a circular table if each member sits next to two members of the other party.

We can use counting principle, which helps to count all the possible outcomes and the total possible ways different events can be occur. For this ,choose any 5 consecutive seats to place the Democrats, it doesn't matter which 5 consecutive seats that we choose, since we can rotate the table. Then there are 5 ways to place first member out of 5 democrats. The places available for 2nd member is 4 i.e 4 ways , similarly total ways to place the democrats in their seats. Thus, the Democrats occupy the other 5 seats and they can be arranged in the same muber of ways = 5! = 120 ways. Similarly, total ways to arrange the 5 republicans are 5! = 120 ways.

Midpoints are A(a, b), B(a+c, b+d), C(2c, d), D(c, 0)

slope AB = slope DC = d/c

slope AD = slope BC = b/(a-c)

Given that Quadrilateral R S T V is in a coordinate plane with vertex and R(0, 0), S(2a, 2b), T(2c, 2d), V(2c, 0).

A is the midpoint of RS, B is the midpoint of ST

C is the midpoint of TV, and D is the midpoint of RV

The midpoint M of segment PQ:

M = (P +Q)/2

A = (R +S)/2 = ((0, 0) +(2a, 2B))/2 = (a, b)

B = (S +T)/2 = ((2a, 2b) +(2c, 2d))/2 = (a+c, b+d)

C = (T +V)/2 = ((2c, 2d) +(2c, 0))/2 = (2c, d)

D = (R +V)/2 = ((0, 0) +(2c, 0))/2 = (c, 0)

The slope of various segments can be found using the slope formula:

m = (y2 -y1)/(x2 -x1)

So, the slopes of the various segments are ...

slope of AB = (b +d -b)/(a +c -a) = d/c

slope of DC = (0 -d)/(c -2c) = -d/-c = d/c . . . . same as slope AB

slope of AD = (0 -b)/(c -a) = -b/(c -a) = b/(a-c)

slope of BC = (d -(b+d))/(2c -(a+c)) = -b/(c -a) = b/(a-c) same as slope AD

By solving an equation for general taxes, we will find that the percent sales tax on the pair of sneakers is 5%.

We know that for an object with a price P, and a tax of X (where X is in a percentage) the price after the tax is:

P' = P*(1 + X/100%)

Here we know that the initial price is $48 and the price after tax is $50.40, so we will get:

$50.40 = $48*(1 + X/100%)

Now we can solve this for X.

($50.40/$48) = 1 + X/100%

(($50.40/$48) - 1)*100% = X

5% = X

So the percent sales tax is 5%.
