#SPJ2

Final answer:

Billy could drive 256.5 miles in 4.5 hours.

Explanation:

To find the number of miles Billy could drive in 4.5 hours, we will use the concept of direct variation. Direct variation states that when two variables are directly proportional, their ratio is constant.

Given that Billy drives 171 miles in 3 hours, we can set up a proportion:

Miles driven / Hours in the car = Miles driven / Hours in the car

Using the given values, we have:

171 / 3 = x / 4.5

To solve for x, cross multiply:

3x = 171 * 4.5

Divide both sides by 3:

x = (171 * 4.5) / 3

Simplifying the right side of the equation gives us:

x = 256.5

Therefore, Billy could drive 256.5 miles in 4.5 hours.

How to complete the square when a is greater than 1?

Answers

when a is greater then 1...

example : 

2x^2 + 6x + 3 = 0.....x^2 has to have a coefficient of 1 in order to complete the square. So, in this case, we divide everything by 2.

x^2 + 3x + 3/2 = 0....now u move the constant over
x^2 + 3x = -3/2...and continue as usual.

just remember, u have to divide by the coefficient of x^2 before moving the constant over.

Final answer:

The density of the cube is calculated to be 2 g/cm³ by dividing the mass (250 grams) by the volume of the cube (125 cm³).

Explanation:

To calculate the density of a substance, you divide its mass by its volume. In the given problem, the cube has a mass of 250 grams and each side of the cube is 5 cm. The volume of a cube is calculated by taking the cube of the side length, which in this case is 5^3 = 125 cm³.

The Porter family is moving from Baltimore, Maryland, to San Francisco, California. They would like to know what the difference will be in their family budget. How would you explain cost of living to them?

Answers

In a business perspective, we need to consider cost of living and rent index (considering they will rent in both cities) difference in response to net earnings. Per data in general, we can say that it would cost ~$5000+ to live in California and around $4000+ in Maryland. These values should be directly related to the indices difference of these underlying factors: consumer prices (CA is 4% lower than MD), consumer prices + rent (CA is 7% higher than MD), rent (CA is 28% higher than MD), restaurant (CA is 3% lower than MD), groceries (CA is 4% lower than MD), and local purchasing power is 10% higher in CA than MD.

Identify a reflection about the x-axis or a reflection about the y-axis of ƒ(x) = 7x2 – x3 by observing the equation of the function g(x) = –7x2 + x3.

Answers

Final answer:

The function g(x) = –7x² + x³ is the reflection of the function f(x) = 7x² – x³ about the x-axis. This is observed by the change in signs of each term in the function's equation after performing the reflection.

Explanation:

By observing the given equation, f(x) = 7x² – x³ and g(x) = –7x² + x³, it is clear that the function f(x) reflects about the x-axis to create function g(x). This is indicated by the change of signs of each term in the equation of the function.

To elaborate, a reflection about the x-axis sees a function's equation change y(x) to -y(x). In our example, f(x) becomes -f(x) or –(7x² – x³), which after simplifying gives us –7x² + x³ = g(x). Therefore, g(x) is the reflection of f(x) about the x-axis.

Furthermore, to identify a reflection about the y-axis, observe if the equation changes from f(x) to f(-x). An even function or a function symmetric about the y-axis would not change with this transformation. Conversely, an odd function would change signs, just like our function did when reflecting over the x-axis.

Eddie purchased 4 packages of light bulbs and received a 15% discount. He also paid $4.85 in taxes on his purchase. Write an algebraic expression to represent the total amount Eddie paid. Let x represent the cost of each package purchased.

Answers

Okay. An algebraic expression we can use here is 4x * 0.85 + 4.85= t. I say this, because "x" equals the amount paid per package of light bulbs and he paid for 4 of them. He received a 15% discount for purchasing 4 packages of light bulbs, but he would still have to pay 85% (0.85 in decimal form) of the price. Then, $4.85 are added to his purchases. I put the "t" in the algebraic expression to represent the total cost of the purchase together, including tax and discount. The algebraic expression is 4x * 0.85 + 4.85.

In exercises 83–86, verify that the intermediate value theorem applies to the indicated interval and find the value of guaranteed by the theorem.

Answers

The intermediate value theorem states that suppose f is a function continuous on every point of the interval [a, b], for any L between the values f(a) and f(b), there exist at least one number, c, in [a, b] for which f(c) = L.

83.
Given
[tex]f(x)=x^2+x-1[/tex]
on the interval [0, 5], with f(c) = 11

[tex]f(0)=0^2+0-1=-1[/tex]
and
[tex]f(5)=5^2+5-1=25+4=29[/tex]
Clearly, f(c) = 11 is between f(0) = -1 and f(5) = 29

Thus, the intermediate value theorem is satisfied.

To find the value of c, we solve the equation
[tex]c^2+c-1=11[/tex]
as follows:
[tex]c^2+c-1=11 \\ \\ c^2+c-12=0 \\ \\ (c-3)(c+4)=0 \\ \\ c=3 \ or \ -4[/tex]

[tex]f(0)=0^2-6(0)+8=8[/tex]
and
[tex]f(3)=3^2-6(3)+8=9-18+8=-1[/tex]
Clearly, f(c) = 0 is between f(0) = 8 and f(3) = -1

Thus, the intermediate value theorem is satisfied.

To find the value of c, we solve the equation
[tex]c^2-6c+8=0[/tex]
as follows:
[tex]c^2-6c+8=0 \\ \\ (c-4)(c-2)=0 \\ \\ c=4 \ or \ 2[/tex]

Because, c is in the interval [0, 3], therefore, the value of c is 2.

[tex]f(3)=3^3-3^2+3-2=27-9+1=19[/tex]
Clearly, f(c) = 4 is between f(0) = -2 and f(3) = 19

Thus, the intermediate value theorem is satisfied.

How do you find the coordinates of the midpoint of segment VW with the end points of V(-2,-6) and W(x+2, y+3)

Answers

Final answer:

The coordinates of the midpoint of segment VW are (x/2, (y-3)/2).

Explanation:

To find the coordinates of the midpoint of segment VW, we can use the midpoint formula.

The midpoint formula states that the x-coordinate of the midpoint is the average of the x-coordinates of the endpoints, and the y-coordinate of the midpoint is the average of the y-coordinates of the endpoints.

Given the endpoints V(-2, -6) and W(x+2, y+3), we can find the x-coordinate of the midpoint by taking the average of the x-coordinates: (-2 + (x+2))/2.

Similarly, we can find the y-coordinate of the midpoint: (-6 + (y+3))/2.

So the coordinates of the midpoint are (x/2, (y-3)/2).

You have $20 to spend on taxi fare. The ride costs $5 plus $2.50, per mile.

Answers

it would be $2.50 per mile
I am assuming you are asking how many miles you can travel on the taxi.

In this situation a good method would be to make an equation.

Let x represent the number of miles traveled.
The ride costs $2.50 per mile, so the cost of the total trip is equal to 2.5x + 5. (the 5 is the base 5$ cost)

Set this equation equal to 20 as you have $20 to spend.

So, we get
2.5x + 5 = 20
Subtract 5 on both sides to get:
2.5x = 15
Divide by 2.5 on both sides to find x. 
x = 6

You can travel 6 miles in the taxi.

Explanation:

In order to find the value of 'x' in both cases, we need to understand that two different concepts potentially apply; Pythagoras theorem for the triangle, and algebra for the rectangle. The Pythagorean theorem applies to right angle triangles and is expressed as x² + y² = h² where 'x' and 'y' are sides and 'h' is the hypotenuse. In a rectangle, to find 'x' related to an equation like y = 9 + 3x, you substitute values for 'y' and solve for 'x'. An example is given in Table A1 where we see an instance of substituting values for 'x' and then calculating what value of 'y' results. These points are then plotted on a graph.

Sample space of 2 dice ={6 x 6} = 36 possible outcomes
In how many ways we can get 7:
1) 1+6
2) 2+5
3) 3+4
4) 4+3
5) 5+2
6) 6+1
So there are 6 ways to get a 7,

Hence P(of getting a sum =7) = 6/36 = 1/6 = 0.1667



Final answer:

When two dice are rolled, there are 6 feasible outcomes out of 36 that will sum to '7', hence the probability is 1 out of 6, or approximately 0.167.

Explanation:

In the field of probability, when you roll two dice, there are 6 possible outcomes for each die, hence giving us 36 possible outcomes altogether (6*6=36). Out of these 36 possible outcomes, there are 6 combinations that can total to '7'. These combinations are: (1,6), (2,5), (3,4), (4,3), (5,2), and (6,1). Therefore, the probability of rolling a '7' with two dice is 6 out of 36, which simplifies to 1 out of 6, or approximately 0.167, when rounded to three decimal places.

If 2a/b=1/2,what is the value of b/a?

Answers

Answer:

The value of [tex]\frac{b}{a}=4[/tex] .

Step-by-step explanation:

As given in the question

[tex]\frac{2a}{b}=\frac{1}{2}[/tex]  

Now find out the value of [tex]\frac{b}{a}.[/tex]

[tex]\frac{b}{a}=\frac{2\times 2}{1}[/tex]

[tex]\frac{b}{a}=2\times 2[/tex]

[tex]\frac{b}{a}=4[/tex]

Therefore the value of [tex]\frac{b}{a}=4[/tex] .

The value of b/a from the equation; 2a/b=1/2 is; 4

Evaluation of inverse

The given equation is;

2a/b=1/2

Divide both sides of the equation by 2; we have;

a/b = 1/2 ÷ 2

a/b = 1/4

Hence, the inverse of a/b is b/a and;

b/a = 4
