The cost of each table is $110.

Given:

Total Amount spent = $900

Cost of bookshelf = $50

By dividing the entire amount paid by 70%, you may calculate the cost of the chair and desk.

Cost of chair and desk = 900 x 0.70 = $60

Now, subtract that cost from the total amount spent:

900 - 630 = $270 was spent on the rest three items.

Next, subtract the cost of the bookshelf:

270 - 50 = $220

The cost of two tables is $220.

So, the price of one table can be calculated by dividing this cost by 2:

220/2 = $110

All the Individuals solutions are solved below:

a) To verify that y = e^m_1x - e^m_2 x/m_1 - m_2 is a solution of the differential equation y" - (m_1 + m_2)y' + m_1 m_2y = 0, we can substitute y into the equation and simplify:

y" = m_1^2e^m_1x - m_2^2e^m_2x

y' = m_1e^m_1x - m_2e^m_2x

so:

y" - (m_1 + m_2)y' + m_1 m_2y = m_1^2e^m_1x - m_2^2e^m_2x - (m_1 + m_2)(m_1e^m_1x - m_2e^m_2x) + m_1 m_2(e^m_1x - e^m_2x/m_1 - m_2) = 0

b) To find the limit of the solution in part (a) as m_1 right arrow m_2, we can use I'Hospital's rule. The limit is:

lim (m_1 -> m_2) e^m_1x - e^m_2 x/m_1 - m_2 = e^m_2x - e^m_2 x/m_2 - m_2 = e^m_2x - e^m_2x - m_2 = -m_2

c) To verify that the limit in part (b) satisfies the differential equation obtained from the equation in part (a) by replacing mi by m_2, we can substitute -m_2 into the equation:

y" - (m_2 + m_2)y' + m_2 m_2y = 0

y" - 2m_2y' + m_2^2y = 0

which is the differential equation of a constant function, and -m_2 is a constant function. Therefore, the limit in part (b) satisfies the differential equation.

It should be noted that the solution y = e^m_1x - e^m_2 x/m_1 - m_2 is a linearly independent solution of the differential equation y" - (m_1 + m_2)y' + m_1 m_2y = 0, and it can be used in combination with the general solution y = c_1e^m_1x + c_2e^m_2x to find the general solution of the differential equation.

Assuming that each site is equally likely to be chosen, there are 1820 ways the sites for the new stores can be selected.

The department store chain is planning to expand into a new market and is considering 16 different sites on which to locate 4 stores. In order to determine the number of ways to select the sites for the new stores, we need to calculate the number of ways to select 4 sites from the 16 available sites. This can be done by using the binomial coefficient "16 choose 4" which is also written as,

16C4 = 16!/(4! * 12!)

Using this formula, we can calculate the number of ways to select 4 sites out of 16 as 1820 ways.

This means that the store chain has 4845 different ways to select the 4 sites from the 16 available sites assuming each site is equally likely to be chosen.

The probability that Steve chooses two different types of biscuits is 5/11 (or approximately 0.4545).

To calculate this, we need to consider the different combinations of two biscuits that Steve can take from the tin. There are two digestive biscuits, three chocolate biscuits, and seven ginger biscuits, so the total number of possible combinations is 12.

The number of combinations where he chooses two different types of biscuits is 5 (2 digestive and 1 chocolate, 2 digestive and 1 ginger, 1 chocolate and 1 ginger).

Therefore, the probability of choosing two different types of biscuits is 5/12, which is 0.4545.

At a constant speed of 45 miles per hour it will take 0.71 hours for Darla to run her errands and get back home.

What is constant speed?

An object is considered to be moving at a constant speed when it covers the same distance in the same amount of time. When moving at a constant pace, an object covers a certain distance in a fixed amount of time.

Darla drives at a constant speed of 45 miles per hour.

She drives for y miles and it takes her x hours.

The number of miles Darla can drive in x hours is y = 45x.

Darla drives to the market, 14 miles from her house.

Then she drives to the post office, 3 miles from the market.

Then she drives back to her house, 15 miles from the post office.

Calculate Darla's total distance travelled -

14 + 3 + 15 = 32 miles

Now, substituting the value of y with 32 -

32 = 45x

x = 32/45

x = 0.71

Therefore, the time taken by Darla is 0.71 hours.

The volume of the parallelepiped with adjacent edges PQ, PR, and PS     is V=16  

Let the parallelepiped be PQRS.

The vertices of parallelepiped are P(3, 0, 1), Q(-1, 2, 5), R(5, 1, -1), S(0, 4, 2).

Given three vectors, there is a product, called scalar triple product, that gives (the absolute value of it), the volume of the parallelepiped that has the three vectors as dimensions.

So

PQ=(3+1,0-2,1-5)=(-4,-2,-4)

PR=(-2-1,-1-4,0+1)=(-2,-1,2)

PS=(-2-3,1-6,0-1)=(3,-4,-1)

The scalar triple product is given by the determinant of the matrix (3×3)

that has in the rows the three components of the three vectors:

|-4 -2 -4|

|-2 -1 +2|

|3 -4 -1|

and the determinant is given for example with the Laplace rule choosing the first row:

a(ad-bc)-b(ad-bc)+c(ad-bc)

=4⋅[(−1)(−1)−(2)(−4)]−(−2)[(−2)(−1)−(2)⋅(3)+(−4)[(−2)(−4)−(−1)(3)]

=4(1+8)+2(2−6)−4(8+3)

From the given information,

Atiku is allowed a discount of 12.5% on a dress that cost $125

First, we will calculate the discount

Discount = 12.5% of $125

Discount = 0.125 × $125

Discount = $15.625

Amount paid = Cost - Discount

Thus,

Amount paid = $125 - $15.625

Answer:

Step-by-step explanation:

a) To find u1, we can use the term-to-term rule given in the problem:

Un+1 = U²₁ + 5

We know that u1 = 1, so we can substitute that into the equation:

u2 = 1² + 5 = 1 + 5 = 6

b) To find u2, we can use the same term-to-term rule and substitute the value of u1 (which is 6) into the equation:

u3 = 6² + 5 = 36 + 5 = 41

c) To find un, we can use the term-to-term rule and substitute the value of un-1 into the equation.

un = un-1² + 5

It's important to note that the value of n is not given so we can't calculate the value of un.

Therefore, u1 = 6, u2 = 41, and we can't calculate un without knowing the value of n.

Step-by-step explanation:

Let x be the number of tickets sold before the tournament.

The number of tickets sold on the day of the tournament is x - 150 (since 150 fewer tickets were purchased on the day of the tournament than before the tournament)

The total number of tickets sold is the sum of the number sold before the tournament and on the day of the tournament.

x + (x - 150) = 898

Combining like terms:

2x = 1048

To find the number of tickets sold on the day of the tournament, we need to divide by 2:

x = 1048/2

x = 524

Therefore, 524 tickets were sold before the tournament and x - 150 = 524 - 150 = 374 tickets were sold on the day of the tournament.

Using factorization, the zeros of the polynomial y = 3p³ - 8p² + 4p are 0, 2/3 and 2.

The values of the independent variable (x) for which the function equals zero are referred to as the zeros of a function, also known as the roots or solutions. They are, in other words, the x-coordinates of the spots where the function's graph crosses the x-axis. You can set a function's value to zero and then work out the value(s) of x that the equation requires in order to identify the zeros of the function.

If the function, for instance, is f(x), then you would set f(x) to 0 and then solve for x:

f(x) = x^2 + 2x - 3 = 0

This can be simplified as

(x-3)(x+1) = 0

Taking the x - values

x - 3 = 3

or

x + 1 = -1

hence;

x^2 + 2x - 3 = -1, 3

Therefore, -1 and 3 are the zeros of the function f(x) = x2 + 2x - 3.

In our given problem;

y = 3p³ - 8p² + 4p

what are expressions?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.

e.g. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.
