the yellow cab company charges a flat fee of $3.50 and an additional $2.50 per mile. the relaxicab company charge $2.30 per mile and a $4.54 fee. at how many miles do the two companies charege the same amount? write a system of equations that computes the cost of the cabs. use for the miles, and for the cost.

Answers

Step-by-step explanation:

Since the initial fee is fixed, we can assume it is a constant and the succeeding mile fee is the variable as it changes for every mile covered.

Let x = distance (mile)

let y = total charge (dollars)

Yellowcab company equation for cost calculation;  3.50 + 2.5x = y

laxicab company equation for cost calculation;  4.54+2.3x = z

the two companies charge the same amount when y = z

; 3.50 + 2.5x = 4.54+2.3x

x = 5.2 miles

COST CALCULATION

;3.50 + 2.5x = ?

if x = 5.2;

; 3.50 + 2.5(5.2) =$16.50

OR

; 4.54+2.3x = ?

; 4.54 + 2.3(5.2) = $16.50

Answers

If we change x by -0.7, we can expect the value of f(x) to decrease by approximately 2.1 units.

Assuming you meant to say "let f be a differentiable function where f(9) = 4 and f'(9) = 3. If we change x by -0.7 and we change y by 0.3, then we can expect the value of f(x) to change by approximately what amount?"

Using the linear approximation formula, we have:

\(Δf(x) ≈ f'(9) Δx\)

where Δx = -0.7 and we want to find Δf(x) when Δy = 0.3.

We can rearrange the formula to solve for Δf(x):

\(Δf(x) ≈ f'(9) Δx\)

Δf(x) ≈ 3(-0.7)

Δf(x) ≈ -2.1

This means that if we change x by -0.7, we can expect the value of f(x) to decrease by approximately 2.1 units. However, this is only an approximation based on the linear behavior of the function near x = 9, so it may not be exactly accurate for large changes in x.

Jay decides to take out a $12,000 student loan during his first year in college. If he is charged 4.5% interest that is compounded annually, how much will the total loan amount equal in four years when he graduates?

Answers

Answer:

2,160.00

Step-by-step explanation:

okay so first we have to find 4.5% of 12,000

which is 540, then multiply 540 by the four years and

540 x 4 = 2,160.00

The total loan amount would be equal to $14,310 in four years when Jay graduates.

Given the following data:

Principal = $12,000Interest rate = 4.5%Time = 4 years

To determine how much (future value) the total loan amount would equal in four years when he graduates:

Mathematically, compound interest is given by the formula:

\(A = P(1 + r)^{t}\)

Where;

A is the future value.P is the principal or amount borrowed.r is annual interest rate.t is the number of years for the compound interest.

Substituting the given parameters into the formula, we have;

The equation of the statement "6 more than twice the number is 22 is" :

What is meant by an equation?

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. Two expressions are combined in an equation using an equal symbol ("="). The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign. Typically, we consider an equation's right side to be zero. As we can balance this by deducting the right-side expression from both sides' expressions, this won't reduce the generality.

Assuming the complete question is as given in the figure below.

We can assume the number is x.

Now it is given that 6 more than twice the number is 22.

W can write this as a mathematical equation.

It is given that we are taking twice the number x.

This can be written as 2x.

Now to write an equation, it is given 6 more than 2x is equal to 22.

let f be the function given by and g be the function given by . find the first four nonzero terms and the general term for the power series expansion of f(t) about t

Answers

The Taylor series formula in summation notation f(t) = Σ[n=0 to infinity] { (1/n!)f^n(a)(t-a)^n } where f^n(a) denotes the nth derivative of f(t) evaluated at t = a.

Since the functions f(t) and g(t) have not been given in the question, I cannot provide a specific answer to this question. However, I can provide a general approach to finding the power series expansion of a function about a point.

To find the power series expansion of a function f(t) about a point t = a, we can use the Taylor series formula:

f(t) = f(a) + f'(a)(t-a) + (1/2!)f''(a)(t-a)^2 + (1/3!)f'''(a)(t-a)^3 + ...

where f'(a), f''(a), f'''(a), ... are the first, second, third, and higher-order derivatives of f(t) evaluated at t = a.

To find the first four nonzero terms of the power series expansion, we can calculate the values of f(a), f'(a), f''(a), and f'''(a) at t = a, substitute them into the Taylor series formula, and simplify the resulting expression. The first four nonzero terms will be the constant term, the linear term, the quadratic term, and the cubic term.

To find the general term of the power series expansion, we can write the Taylor series formula in summation notation:

f(t) = Σ[n=0 to infinity] { (1/n!)f^n(a)(t-a)^n }

where f^n(a) denotes the nth derivative of f(t) evaluated at t = a. The general term of the power series expansion is given by the expression in the curly braces. We can use this expression to find any term in the series by plugging in the appropriate values of n and f^n(a).

10) water is pouring into a trough at a rate of 1.5 cubic feet per minute. the trough is 10 feet long, 4 feet tall, and 3 feet wide at the top. the cross section is an isosceles triangle. how fast is the water level rising when the depth of the water is 1 foot?

Answers

The water level is rising at a rate of 0.05 feet per minute when the depth of the water is 1 foot.

The rate at which the water level is rising when the depth of the water is 1 foot can be determined by finding the rate of change of the volume of water with respect to time and dividing it by the cross-sectional area of the trough.

The trough has an isosceles triangle cross section. Given that the trough is 10 feet long, 4 feet tall, and 3 feet wide at the top, we can determine the shape of the cross section using similar triangles.

Since the cross section is an isosceles triangle, the width of the cross section at any depth will be proportional to the depth itself. Let's denote the depth of the water as h.

To find the cross-sectional area, we can use the formula for the area of a triangle: A = (1/2) * base * height. The base of the triangle is 2w, where w is the width of the cross section at a depth h. Since the width is proportional to the depth, we can express it as w = (3/4)h.

Therefore, the cross-sectional area can be calculated as A = (1/2) * 2w * h = 3/2 * h^2.To find the rate at which the water level is rising, we need to determine the rate of change of the volume of water with respect to time. The volume of water in the trough is V = A * x, where x represents the length of the trough. The rate of change of volume with respect to time is dV/dt.

Given that the rate of water pouring into the trough is 1.5 cubic feet per minute, we have dV/dt = 1.5.By substituting the expression for the cross-sectional area A = 3/2 * h^2 and the length of the trough x = 10 into the volume equation, we get V = (3/2) * h^2 * 10 = 15h^2.

Taking the derivative of both sides with respect to time, we have dV/dt = d(15h^2)/dt = 30h * dh/dt.

Solving for dh/dt, we get dh/dt = (1/30) * dV/dt = (1/30) * 1.5.

Therefore, the water level is rising at a rate of (1/30) * 1.5= 0.05 feet per minute when the depth of the water is 1 foot.

I am bitterly opposed to my country entering the war, but if, notwithstanding my opposition, we do enter it, all of my energy and all of my power will be behind our flag in carrying it on to victory.The resolution now before the Senate is a declaration of war. Before taking this momentous step, and while standing on the brink of this terrible vortex, we ought to pause and calmly and judiciously consider the terrible consequences of the step we are about to take. We ought to consider likewise the route we have recently traveled and ascertain whether we have reached our present position in a way that is compatible with the neutral position which we claimed to occupy at the beginning and through the various stages of this unholy and unrighteous war.No close student of recent history will deny that both Great Britain and Germany have, on numerous occasions since the beginning of the war, flagrantly violated in the most serious manner the rights of neutral vessels and neutral nations under existing international law, as recognized up to the beginning of this war by the civilized world.The reason given by the President in asking Congress to declare war against Germany is that the German government has declared certain war zones, within which, by the use of submarines, she sinks, without notice, American ships and destroys American lives ... The first war zone was declared by Great Britain. She gave us and the world notice of it on, the 4th day of November, 1914. The zone became effective Nov. 5, 1914 ... This zone so declared by Great Britain covered the whole of the North Sea ... The first German war zone was declared on the 4th day of February, 1915, just three months after the British war zone was declared. Germany gave fifteen days' notice of the establishment of her zone, which became effective on the 18th day of February, 1915. The German war zone covered the English Channel and the high seawaters around the British Isles ...Both excerpts are addresses to Congress about entering war, and they both use rhetoric appeals. What types of appeals are primarily used in each excerpt? Excerpt 1 uses logos and Excerpt 2 uses logos. Excerpt 1 uses logos and Excerpt 2 uses kairos.

Your answer 29.798 g was either rounded differently or used a different number of significant figures than required for this part. Part C HCN forms when synthetic fibers containing Orlon or Acrilan burn. Acrilan has an empirical formula of CH, CHCN, so HCN is 50.9% of the formula by mass. A rug in the laboratory measures 12.0x 12.0 ft and contains 30.0 oz of Acrilan fibers per square yard of carpet. If the rug burns, what mass of HCN will be generated in the room? Assume that the yield of HCN from the fibers is 20.0% and that the carpet is 40.0 % consumed. Express your answer to three significant figures and include the appropriate units.
