the total area under the curve is 2400.

To find the number of vehicles that pass the intersection between time t = 0 and time t = 8, we need to calculate the definite integral of the function R(t) from t = 0 to t = 8:

∫(0 to 8) R(t) dt

Looking at the graph of R(t), we can see that it consists of two parts: a rectangle with base 2 and height 600, and a triangle with base 6 and height 400. The area of the rectangle is 2 x 600 = 1200, and the area of the triangle is (1/2) x 6 x 400 = 1200. Therefore, the total area under the curve is 2400.

So, the number of vehicles that pass the intersection between time t = 0 and time t = 8 is:

∫(0 to 8) R(t) dt = 2400

Since R(t) is measured in vehicles per hour, this means that 2400 vehicles pass the intersection between time t = 0 and time t = 8. Therefore, the answer is 2400, which is not one of the given answer choices.

Answer:

y=-x/3+2

Step-by-step explanation:

If you graph out 3x-y-7=0, you will get a line that goes through the points (0, -7), and about (2.3, 0). If you graph out y=x/3+2, you have to make sure that this line forms a 90 degree angle on the previous line, thus making this line perpendicular to the previous line.

Landon had 2/5 gallons of juice leftover from a party, and after giving some to his cousin, he had 3/5 gallons left. He gave his cousin "x - 1" gallons, where "x" is the original amount of juice.

Let's start by defining the amount of juice Landon had originally as "x". We know that he had 2/5 gallons of juice leftover after the party, which means that he had used up x - 2/5 gallons of juice during the party.

We also know that after giving his cousin some juice to take home, he had 3/5 gallons of juice left. So, we can set up an equation:

x - 2/5 - y = 3/5

where "y" is the amount of juice Landon gave his cousin.

To solve for "y", we can simplify the equation:

x - 2/5 - y = 3/5

x - y = 1

y = x - 1

Therefore, Landon gave his cousin "x - 1" gallons of juice.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

Given that the cost of Costa Rican coffee that sells for $7 per pound and Kenyan coffee that sells for $10.

The cost of the mixture is $8.5 per pound.

Assume that the manager mixed 80 pounds of the Kenyan coffee with the x pound of the Costa Rican coffee to get a mixture.

The cost of 80 pound Kenyan coffee is $(80×10) = $800.

The cost of x pound Costa Rican coffee is 7x.

The cost of mixture coffee is (80 + x)8.5

According to the question:

800 + 7x = (80 + x)8

800 + 7x = 640 + 8.x

640 + 8x = 800 + 7x

Answer:

The perimeter of triangle XYZ is 54 cm

Step-by-step explanation:

∵ Δ ABC is similar to Δ XYZ

∵ The longest side in Δ XYZ is 25.2 cm

→ That means its corresponding side in Δ ABC is the longest side

∵ AB = 18 cm, BC = 30 cm, CA = 42 cm

∴ The longest side in Δ ABC is CA

∴ CA is the corresponding side of the side of length 25.2 cm

∴ The ratio of similarity = \(\frac{25.2}{42}\) = 0.6 ⇒ (r)

∵ The perimeter of Δ ABC = AB + BC + CA

∴ The perimeter of Δ ABC = 18 + 30 + 42

∴ The perimeter of Δ ABC = 90 cm

→ Use the 2nd fact above

∵ P of Δ XYZ = r × P of Δ ABC

∵ r = 0.6 and P of Δ ABC = 90

∴ The perimeter of Δ XYZ = 0.6 × 90

∴ The perimeter of Δ XYZ = 54 cm

Answer:

x=3.6, y=-2.5

Step-by-step explanation:

we have:

5x+4y=8

10x-4y=46

add across to get rid of y (5x+10x=15x, 4y+(-4)=0y, 8+46=54:

15x=54

dividing both sides by 15

x=3.6

input x=3.6 into any of the first two equations, I'll use the first:

5x+4y=8

5(3.6)+4y=8

18+4y=8

subtract 18 on both sides

4y=-10

y=-10/4=-2.5

y=-2.5

The answer to the question is True. This can be answered by the concept of Trigonometry.

First, let's recall the definitions of the asymptotic notations used in the question

f(n) = O(n²) means that there exists a positive constant c and a positive integer N such that f(n) <= c × n² for all n >= N.

g(n) = Theta(n²) means that there exist positive constants c1, c2, and a positive integer N such that c1 × n² <= g(n) <= c2 × n² for all n >= N.

Now, since f and g are non-decreasing positive functions, we can assume without loss of generality that N > 0 and c1 > 0. Then, for all n >= N, we have:

f(n) <= c × n² (by the definition of O notation)

c1 × n² <= g(n) <= c2 × n² (by the definition of Theta notation)

Multiplying the first inequality by c1, we get:

c1 × f(n) <= c × c1 × n²

Since c1 and n^2 are positive, we can divide both sides by n² to obtain:

c1 × (f(n) / n²) <= c × c1

Now, let's define a new function h(n) = f(n) / n². Since f(n) and n² are both non-decreasing positive functions, h(n) is also non-decreasing and positive. Moreover, for all n >= N, we have:

h(n) <= (c × c1) / c1 = c

Therefore, we have shown that there exists a positive constant c and a positive integer N such that h(n) <= c for all n >= N. This means that h(n) = O(1).

Using this result, we can conclude that:

f(n) = h(n) × n² = O(1) × n² = O(n²)

Therefore, we have:

f(n) = O(n²) and g(n) = Theta(n²) => f(n) = O(g(n))

Therefore, the answer to the question is True.

The 3rd term of the geometric sequence is 6.

In mathematics, an equation is a statement that two expressions are equal. It usually contains one or more variables, which are unknown quantities that can take on different values. Equations are used to represent relationships between quantities, and they can be used to solve problems by finding the values of the variables that make the equation true.

An equation typically consists of two sides, separated by an equal sign. Each side can contain numbers, variables, and mathematical operations such as addition, subtraction, multiplication, division, exponents, and roots. For example, the equation:

2x + 3 = 7

contains the variable x, as well as constants 2, 3, and 7, and mathematical operations of addition and multiplication.

Equations can be solved by applying algebraic techniques to isolate the variable on one side of the equation. For example, to solve the above equation for x, we can first subtract 3 from both sides to get:

2x = 4

Then, we can divide both sides by 2 to get

x = 2

This is the solution to the equation, which means that x must be equal to 2 in order to make the equation true.

Equations are used in many areas of mathematics, including algebra, calculus, geometry, and trigonometry. They are also used in physics, engineering, and other sciences to model physical phenomena and solve problems related to them.

Let's call the first term of the geometric sequence "a" and the common ratio "r".

The formula for the nth term of a geometric sequence is:

an = a *\(r^(n-1)\)

We are given that the 2nd term is 2, so we know that:

a * r = 2 --(1)

We are also given that the 5th term is 432, so we know that:

a * \(r^4\) = 432 --(2)

Now we need to solve for "a" and "r" in order to find the 3rd term.

First, let's solve equation (1) for "a":

a = 2 / r

Now we can substitute this expression for "a" into equation (2):

(2/r) *\(r^4\)= 432

Simplifying, we get:

\(r^3\)= 54

Taking the cube root of both sides, we get:

r = 3

Now we can substitute this value for "r" back into equation (1) to solve for "a":

a * 3 = 2

a = 2/3

So the first term of the sequence is 2/3 and the common ratio is 3.

Now we can use the formula for the 3rd term of a geometric sequence:

a3 = a * \(r^(3-1)\)

a3 = (2/3) *\(3^2\)

a3 = (2/3) * 9

a3 = 6

Therefore, the 3rd term of the geometric sequence is 6.

The area of each parallelogram or triangle is 24 cm²,22.5 cm², 98 ft²,48 cm², 90 m², and  30 in² respectively.

In this skills practice problem, we are asked to find the perimeter and area of each parallelogram or triangle, based on their given dimensions. Let's start by defining the formulas for calculating the perimeter and area of each shape:

Perimeter of a parallelogram = 2 x (length + width)

Area of a parallelogram = base x height

Perimeter of a triangle = sum of the lengths of its sides

Area of a triangle = 1/2 x base x height

Now, let's apply these formulas to each shape:

Parallelogram with length 6 cm and width 4 cm:

Perimeter = 2 x (6 + 4) = 20 cm

Area = 6 x 4 = 24 cm²

Triangle with base 9 cm and height 5 cm:

Perimeter = 9 + 8 + 7 = 24 cm

Area = 1/2 x 9 x 5 = 22.5 cm²

Parallelogram with length 14 ft and width 7 ft:

Perimeter = 2 x (14 + 7) = 42 ft

Area = 14 x 7 = 98 ft²

Triangle with base 12 cm and height 8 cm:

Perimeter = 12 + 8 + 10 = 30 cm

Area = 1/2 x 12 x 8 = 48 cm²

Parallelogram with length 18 m and width 5 m:

Answer:

Step-by-step explanation:

Answer: 35%

Step-by-step explanation:

- To start off divide 100% by the 20$ it began with, it should give you 5%

100/20 = 5

this means that every dollar is worth 5%

- now leaving that aside, subtract 20$ by 13$, it should give you 7$

2--13 = 7

the reason you do this is because since we're looking for the amount reducted, you have to subtract from the beginning amount.

- Finally, with the knowledge gathered, you multiply 5% by the 7$ that were deducted, it should give you 35%

7(5) = 35

The reason we did this is because every dollar is worth 5% and there were 7$ deducted, it results in 35% reduced.

Answer: 35%

Step-by-step explanation: I turned 13 and 20 into 13/20, or 13 out of 20 dollars charged. Then, I multiplied 13/20 by 5/5, which equals 65/100, or 65% or the original price was paid. The other 35% of the 20 dollars wasn’t, because that’s how much of the original price was discounted.

The experimental probability of the coin landing heads up is calculated by dividing the number of times the coin landed heads up (16) by the total number of flips (40). So the experimental probability of the coin landing heads up is:

P(heads up) = 16/40

Simplifying the fraction by dividing both the numerator and denominator by 8, we get:

P(heads up) = 2/5 or 0.4

Therefore, based on the results, the experimental probability of the coin landing heads up is 0.4 or 2/5.

To find the experimental probability of the coin landing heads up, you'll need to use the following formula:

Experimental probability = (Number of successful outcomes) / (Total number of trials)

In this case, the successful outcome is the coin landing heads up, which occurred 16 times. The total number of trials is 40 flips. So, the experimental probability would be:

Experimental probability (heads up) = (16 successful outcomes) / (40 total flips)

Now, divide 16 by 40 to get the probability:

Experimental probability (heads up) = 16/40 = 0.4 or 40%

So, based on the results, the experimental probability of the coin landing heads up is 40%.
