The equation for a​ two-week trip of 500 miles' rental cost is Total rent cost = 2x + 500y

Information about the problem:

To solve this problem, we have to state the equation using the information of the problem:

Car rent for 2 weeks = 2x

Car rent for 500 miles = 500y

Total rent cost = 2x + 500y

Example:

Car rent per week = $280/ week

Car rent per miles = $0.75/ mile

Total rent cost = (2 weeks * $280/ week) + (500 miles * $0.75/ mile)

Total rent cost = $560 + $375

Total rent cost = $935

Answer:

2.08 × \(10^{7}\)

Step-by-step explanation:

Multiply 4 × 5.4 to get 20.8. Then multiply \(10^{-2}\) × \(10^{8}\) = \(10^{6}\)

However, that is not an answer. So, you can divide 20.8 by 10 and multiply \(10^{6}\) × 10.

Then you get 2.08 × \(10^{7}\)

first off let's notice a few things on that function.

the graph "passes" -5, that's a root, the graph "touches" 3 and goes back up, that's another root, but that's a root with an "even multiplicity", the heck does that mean? well, it means there are at least two roots, could be 4 or 6 or 18, so long is even, but we're shooting for the least degree, so we'll settle for 2.

now hmm, let's reword that

what's the equation of a function with roots at -5 and 3 twice, that it passes through (0 , 9)?

\(\begin{cases} x = -5 &\implies x +5=0\\ x = 3 &\implies x -3=0\\ x = 3 &\implies x -3=0\\ \end{cases} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{original~polynomial}{a ( x +5 )( x -3 )( x -3 ) = \stackrel{0}{y}}\hspace{5em}\textit{we also know that } \begin{cases} x=0\\ y=9 \end{cases} \\\\\\ a ( 0 +5 )( 0 -3 )( 0 -3 ) = 9\implies 45a=9\implies a=\cfrac{9}{45}\implies a=\cfrac{1}{5} \\\\[-0.35em] ~\dotfill\)

\(\cfrac{1}{5}(x+5)(x-3)^2=y\implies \cfrac{1}{5}(x+5)(x^2-6x+9)=y \\\\\\ \cfrac{1}{5}(x^3-x^2-21x+45)=y\implies {\Large \begin{array}{llll} \cfrac{x^3}{5}-\cfrac{x^2}{5}-\cfrac{21x}{5}+9=y \end{array}}\)

Answer:From the given information, we know that after sailing for 2 hours, Alvin and his friends are 10 miles from shore. This can be written as y = 10 when x = 2.

Since there is a proportional relationship between x and y, we can write an equation using this information: y = kx, where k is the proportionality constant.

Substituting the known values, we get: 10 = k * 2

Solving for k, we get: k = 10/2 = 5

So, the equation relating x and y is: y = 5x

To find their distance from shore after sailing for 3 hours, we can plug in x = 3 into the equation:

y = 5x

y = 5 * 3

y = 15

So, after sailing for 3 hours, Alvin and his friends are 15 miles from shore.

Step-by-step explanation:

After 2.5 hours, the trains will be 225 miles apart. To find the time it takes for the two trains to be 225 miles apart, we can use the concept of relative velocity. The trains are moving in opposite directions, so their speeds add up.

The combined speed of the two trains is 50 mph + 40 mph = 90 mph.

To calculate the time it takes for them to be 225 miles apart, we divide the distance by the relative speed:

Time = Distance / Speed

Time = 225 miles / 90 mph

Time = 2.5 hours.

Therefore, after 2.5 hours, the trains will be 225 miles apart.

Answer: A random variable.

Step-by-step explanation:

a numerical description of the outcome of an experiment is called a random variable.

The probability that one is selected is the likelihood

The probability that one is selected at least once is 0.704

The sample space is given as:

S = {1,2,3}

The probability that 1 is not selected at all is:

P'(None) = 2/3

The probability that one is selected at least once is calculated using the following complement rule

P(At least once)  = 1 - P(None)^3

This gives

P(At least once) = 1 -(2/3)^3

Evaluate

P(At least once) = 0.704

Hence, the probability that one is selected at least once is 0.704

Answer:

2(n+3)

Step-by-step explanation:

The sum to 3 = n+3

That sum doubled (~twice) = 2(n+3)

Answer:

2(n+3)

Step-by-step explanation:

Let's look at the statement:

'twice the sum of some number and 3'

Twice means 2 multiplied by something.

What is that something? It is the sum of some number and 3.

Let's replace the some number with variable n.

So it becomes the sum of n and 3, which translates to n+3.

So you put the two parts together:

2 multiplied by (n+3), rewritten as 2(n+3).

Answer:

AC is greater than BC because segment AC is the hypotenuse of right triangle ABC, and the hypotenuse is the longest side of a right triangle.

The hypotenuse is the longest side of the triangle. Side AC of the triangle is its hypotenuse, thus greater than BC (segment and angle theorem of a triangle).

A triangle is a shape with three side and angles. Its longest side is referred to as hypotenuse. And this side is usually opposite to the greatest angle. Examples of triangle include: equilateral, isosceles, acute, right angles, obtuse angle etc.

The given question shows that triangle ACB is a right angled triangle. This is because <CBY = \(90^{o}\).

So that;

<CBY + <CBA = \(180^{o}\)

Now comparing side AC with BC:

The segment and angle theorem of a triangle states that: the longest side of a triangle is always opposite to the greatest angle.

Thus, since <CBA is the greatest of the angles here, then AC is the longest side.

Therefore, the side AC is the hypotenuse of the triangle and it is greater than BC.

Answer: Tañísh’ Ec poco la vans two 3 mph

Step-by-step explanation:

In the given right triangle, the perimeter is 12 in.

According to the Pythagorean theorem, in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the length of the two legs (a and b). Hence,

c^2 = a^2 + b^2

In the given triangle,

c = x in

a = 3 in

b = 4 in

Hence,

x^2 = 3^2 + 4^2

x^2 = 9 + 16

x^2 = 25

x = √25

x = 5

The perimeter of a geometric shape is the sum of all its side. Hence,

Perimeter = 3 + 4 + 5 = 12 in

Answer:

Step-by-step explanation:

To find the area of the region bounded by y=9 and y=9sin(x) on the interval [0, π/2], integrate the difference between the two functions with respect to x, using the power reducing identity. The area is 9π/2 - 9.

To find the area of the region in the first quadrant bounded by y=9 and y=9sin(x) on the interval [0, π/2], you need to integrate the difference between the two functions with respect to x. This gives us the following integral:∫[0, π/2] 9 - 9sin(x) dx

To evaluate the integral, you will need to use the power reducing identity for sine: sin²(x) + cos²(x) = 1

=> cos²(x) = 1 - sin²(x)

=> cos(x) = √(1 - sin²(x))

Then, substitute √(1 - sin²(x)) for cos(x) in the integral and use u-substitution to simplify.

Let u = sin(x), then du/dx = cos(x) dx.

Therefore, the integral becomes:

∫[0, π/2] 9 - 9sin(x) dx

= 9x - 9∫[0, π/2] sin(x) dx

= 9x + 9cos(x) [from 0 to π/2]

= 9(π/2) + 9cos(π/2) - 9(0) - 9cos(0)

= 9π/2 + 0 - 0 - 9

= 9π/2 - 9

The area of the region is 9π/2 - 9.

The union of two sets is to avoid counting the same elements twice.

The mathematical logic subfield of set theory investigates sets, which can be loosely defined as collections of objects. Although any object can be combined into a set, set theory, as a mathematical discipline, focuses primarily on those that are relevant to mathematics as a whole.

Given union of set

(A ∪ B),

The set of all objects that are members of either A or B, or both, is the union of the sets A ∪ B.

let us take example,

A = { 1, 2, 3, 4}

B = {3, 4, 5, 6, 7}

(A ∪ B) = { 1, 2, 3, 4} ∪  {3, 4, 5, 6, 7}

we can simply write all of A and B's elements in a single set to avoid duplicates to find A U B.

(A ∪ B) = {1, 2, 3, 4, 5, 6, 7}

Hence the  union of two sets is a set that contains all the elements of both set and avoid duplicates.

The final answer is that Luis paid $3.58 too much for his purchase ($2.30 - $2.21 = $0.09).

Here's an explanation of the calculations:

To determine the total cost of the purchases, we calculate the price of each item, the total cost of each item, and the total cost of all items combined.

1 gallon of milk at $2.89:

Price: $2.89

2 loaves of bread at $2.19 each with a $0.75 discount:

Price per loaf: $2.19

Total cost of 2 loaves: 2 * $2.19 = $4.38

Total cost with discount: $4.38 - $0.75 = $3.63

2 pounds of ham at $6.89 per pound:

Price per pound: $6.89

Total cost of 2 pounds: 2 * $6.89 = $13.78

1/2 pound of cheese at $8.38 per pound:

Price per pound: $8.38

Total cost of 1/2 pound: 0.5 * $8.38 = $4.19

Total cost before tax: $2.89 + $3.63 + $13.78 + $4.19 = $26.47

Now, we calculate the sales tax at 4% to determine the final cost.

4% of $26.47 = $1.06

Final cost: $26.47 + $1.06 = $27.53

Luis paid $29.83 for the items, which means he paid an extra amount.

Amount paid by Luis: $29.83

Amount he should have paid: $27.53

Amount he paid in excess: $29.83 - $27.53 = $2.30

However, the question asks for the amount paid too much after applying the sales tax, so we need to deduct the tax paid on the excess amount.

Tax paid on the excess amount: $2.30 × (1 - 0.04) = $2.21

The final answer is that Luis paid $3.58 too much for his purchase ($2.30 - $2.21 = $0.09).
