The correct ordered pair for the given equation is D. (3,4).

To find the correct ordered pair, we substitute the x-value from each pair into the equation and check if the resulting y-value matches the one in the ordered pair.

Substituting x = 5 into the equation gives us 52 - 2(5) + 1 = 25 - 10 + 1 = 16, which does not match the y-value of 10 in the ordered pair (5,10), so A is not correct.

Substituting x = -1 gives us (-1)2 - 2(-1) + 1 = 1 + 2 + 1 = 4, which does not match the y-value of 3 in (-1,3), so B is not correct.

Substituting x = 1 gives us 12 - 2(1) + 1 = 1 - 2 + 1 = 0, which does not match the y-value of 2 in (1,2), so C is not correct.

Finally, substituting x = 3 into the equation gives us 32 - 2(3) + 1 = 9 - 6 + 1 = 4, which matches the y-value in the ordered pair (3,4), making D the correct answer.

Therefore, the correct ordered pair is D. (3,4).

Explanation:

We started with x = 1 and ended up with y = -2. So the point (x,y) = (1,-2) is on the diagonal line. In other words, point P is located at (1,-2).

Kyle will have more time to play video games

Solution:

From given question,

Kyle’s parents told him that for every 5 hours of homework or reading he completes, he will be able to play 3 hours of video games.

5 hours of homework = 3 hours of video games

Victor’s parents told their son that he can play 30 minutes for every hour of homework or reading time he completed.

1 hour of homework = 30 minutes of playtime

Suppose if victor spends 5 hours doing homework or reading, then he could play,

5 hours of victor homework = 30 minutes x 5 = 150 minutes of play

That is,

150 minutes = 120 + 30 = 2 hours 30 minutes

This 2 hours 30 minutes playtime of victor is less than kyle playtime (which is 3 hours )

So Kyle gets more play time

6.40=$12.60

Step-by-step explanation:

First, make the equation following the problem.

$7.50 + $0.85 = $12.60

Then, find the number of miles.

$7.50 * $0.85 = $6.40

$6.40=$12.60

Don't need to solve it because it is asking for the equation.

This is a linear equation problem in Mathematics. The equation to find out the number of miles for the given total charge would be 7.50 + 0.85m = 12.60. Through algebraic manipulation, it is found that the shuttle travelled 6 miles.

The subject of this question is in the field of Mathematics, specifically under linear equations in algebra. In this problem, the customer is charged a flat fee of $7.50 and then an additional $0.85 per mile. The total charge for this trip was $12.60, and we're tasked with finding the number of miles covered for this charge.

The equation to solve this problem would be 7.50 + 0.85m = 12.60, where 'm' represents the miles. We subtract 7.50 from both sides, then we get: 0.85m = 5.1. To solve for 'm', we divide both sides by 0.85, and we receive m = 6 miles.

You would spend $63.58 on gas per week.

Step-by-step explanation:

Given,

Distance per day = 117 km

Distance in a week = 117*7 = 819 km

1 km = 0.6214 mile

819 km = 819*0.6214 = 508.93 miles

Car's mileage = 42.0 mi/gallons

Let,

x be the gallons for 508.93 miles

x gallons = [tex]\frac{508.93}{42}=12.12[/tex]

Therefore,

12.12 gallons of gas is needed for one week.

1 US gallon = 3.785 liters

12.12 gallons = 12.12*3.785

12.12 gallons = 45.87 liters

Cost of gas per liter = 1.10 euro

Cost of 45.87 liters = 1.10*45.87 = 50.457 euros

1 euro = $1.26

50.457 euros = 1.26*50.457 = $63.58

You would spend $63.58 on gas per week.

15/4 simplified is 3 3/4

Answer:

43/4 - 28/4 = (43 - 28)/4 = 15/4 or 3 3/4

Step-by-step explanation:

10 3/4 - 6 4/4 . The expression means we should find the difference between 10 3/4 and 6 4/4. The best approach to find the difference of this kind of fractions with whole number is by turning each to an improper fraction.

10 3/4 . This whole number fraction can be turn to an improper fraction as follows

10 × 4 + 3 = 43 then 43/4

6 4/4.   4 × 6 + 4 = 28/4.

Now , let's find the difference

The denominator is same, which is 4

Answer:

Here we do not have the options, but ill try to give an answer.

A system of equations is something of the shape:

A1*x + B1*y = C1

A2*x + B2*y = C2

Where this is a linear relationship, you could have a more complex system, but this will work for the example.

If you want to have a unique solution for a system of equations, you need to have the same number of linearly independent equations (this means that the equations are not repeated, like for example in x + y = 2, and 2x + 2y = 4, where the second equation is equal to two times the first one) than the number of variables, so if we have two variables X and Y, we need to have two linearly independent equations.

If we have less, suppose that you have two variables and only one equation, you will have:

A1*x + B1*y = C1

y = (C1 - A1*x)/B1

Here, for each value of x you have a different value of y, so you have infinite solutions.

So for an answer this you need to find the system where the number of linearly independent equations is smaller than the number of variables.

2. 3+2+1(from cross multiplying)= 6

Answer: 6 1/8

Using fraction strips, the result of 3 1/4 + 2 7/8 is 6 1/8.

Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.

Given, Jane is adding 3 1/4 + 2 7/8 using fraction strips.

Fraction strips are rectangular pieces (electronic or copied on paper strips) to represent different parts of the same whole. They can be cut apart and manipulated to see how various parts can be added together to make the whole or compare different fractional amounts for equivalency.

First, we will add fraction parts

=> 1/4 + 7 / 8

We can write 1/4 as 2/8 since they have the same values

=> 2/8 + 7/8

Since now the denominators are the same, therefore we can add the numerators directly. Hence, the sum of 2/8 and 7/8

=> 9/8

=> 8/8 +1/8

=> 1 + 1/8

Thus the sum = 3 + 2 + 1 + 1/8

Sum = 6 + 1/8

therefore, the sum of 3 1/4 + 2 7/8 using fraction strips is 6 1/8.

Answer:

Domain: (-∞,∞) or  -∞ <[tex]x[/tex]<∞

Range: [1,∞) or [tex]y\geq 1[/tex]

Step-by-step explanation:

Given function:

[tex]f(x)=x^2-2x+2[/tex]

To find range and domain of the function.

Solution:

The given function is a second degree function as the highest exponent of the variable is 2. Thus, it is a quadratic function.

For all quadratic functions the domain is a set of all real numbers. So, the domain can be given as: (-∞,∞) or  -∞ <[tex]x[/tex]<∞

In order to find the range of the quadratic function, we will first determine if the function has a minimum point or the maximum point.

For a quadratic equation : [tex]ax^2+bx+c[/tex]

1) If [tex]a>0[/tex] the function will have a minimum point.

2) If  [tex]a<0[/tex] the function will have a maximum point.

For the given function: [tex]f(x)=x^2-2x+2[/tex]

[tex]a=1[/tex] which is greater than 0, and hence it will have a minimum point.

To find the range we will find the coordinates of the minimum point or the vertex of the function.

The x-coordinate [tex]h[/tex] of the vertex of a quadratic function is given by :

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

Thus, for the function:

[tex]h=\frac{-(-2)}{2(1)}[/tex]

[tex]h=\frac{2}{2}[/tex]  [Two negatives multiply to get a positive]

[tex]h=1[/tex]

To find y-coordinate of the vertex can be found out by evaluating [tex]f(h)[/tex].

[tex]k=f(h)[/tex]

Thus, for the function:

[tex]k=f(1)=(1)^2-2(1)+2[/tex]

[tex]k=f(1)=1-2+2[/tex]

[tex]k=f(1)=1[/tex]

Thus, the minimum point of the function is at (1,1).

thus, range of the function is:

[1,∞) or [tex]y\geq 1[/tex]

Step-by-step explanation:

The height of the statue is 19.5 feet.

Why?

We can solve the problem using trigonometric formulas. In this case, we are going to use the trigonometric formula of the tangent.

We know that the person is standing 50ft from the statue, so, it will be the base of the two triangles formed by both angles (elevation and depression)

Using the trignometric formula, we have:

First triangle:

[tex]tg(\alpha )=\frac{h_{1}}{base} \\\\tg(8\°)=\frac{h_{1}}{50ft}\\\\0.14*50ft=h_1\\\\h_1=7ft[/tex]

Second triangle:

[tex]tg(\alpha )=\frac{h_{2}}{base} \\\\tg(14\°)=\frac{h_{1}}{50ft}\\\\0.25*50ft=h_1\\\\h_1=12.5ft[/tex]

Now, the total height of the statue will be:

[tex]TotalHeight=h_1+h_2=7ft+12.5ft\\\\TotalHeight=19.5ft[/tex]

Have a nice day!

In this question, we utilize trigonometry to calculate the height of the statue. By using the tangent of the given angles and the known distance from the observer to the statue, we can find the lines of sight when looking up and down. Subtracting these two measurements gives us the height of the statue, which we find to be 5.2ft.

This question is about applying trigonometry to find the height of an object, in this case, a statue. First, we need to find the height of the line of sight when the person looks up and when they look down. The height for the line of sight when looking up can be found using the formula for the tangent of an angle: tan(θ) = opposite side/adjacent side. Applying this formula, we find that the height of this line of sight is tan(8°) * 50ft = 7.1 ft. Similarly, when looking down, the height is tan(14°) * 50ft = 12.3 ft.

The height of the statue is the difference between these two heights. Therefore, we find: 12.3ft - 7.1ft = 5.2ft

This is a simple application of the concept of the tangent of an angle in a right triangle, a basic part of trigonometry.

Answer:

[tex]\frac{24}{25}[/tex]

Step-by-step explanation:

Given

cosA = [tex]\frac{3}{5}[/tex] = [tex]\frac{adjacent}{hypotenuse}[/tex]

Then the opposite side using Pythagorean triple is 4, thus

sinA = [tex]\frac{4}{5}[/tex]

Using the trigonometric identity

sin2A = 2 sinAcosA, then

sin2A = 2 × [tex]\frac{4}{5}[/tex] × [tex]\frac{3}{5}[/tex]

         = [tex]\frac{2(4)(3)}{5(5)}[/tex] = [tex]\frac{24}{25}[/tex]

Answer:

[tex]\sin(2A)=\frac{24}{25}[/tex]

Step-by-step explanation:

Double angle identity for sine is

[tex]\sin(2A)=2\sin(A)\cos(A)[/tex].

We know [tex]\cos(A)[/tex]. We now need to find [tex]\sin(A)[/tex] to find our answer.

Recall the following [tex]Pythagorean Identity[/tex]:

[tex]\sin^2(A)+\cos^2(A)=1[/tex].

Replace [tex]\cos(A)[/tex] with [tex]\frac{3}{5}[/tex]:

[tex]\sin^2(A)+(\frac{3}{5})^2=1[/tex]

[tex]\sin^2(A)+\frac{9}{25}=1[/tex]

Subtract [tex]\frac{9}{25}[/tex] on both sides:

[tex]\sin^2(A)=1-\frac{9}{25}[/tex]

[tex]\sin^2(A)=\frac{25}{25}-\frac{9}{25}[/tex]

[tex]\sin^2(A)=\frac{25-9}{25}[/tex]

[tex]\sin^2(A)=\frac{16}{25}[/tex]

Now to finally get the value of [tex]\sin(A)[/tex] take the square of both sides:

[tex]\sin(A)=\pm \sqrt{\frac{16}{25}}[/tex]

Since [tex]A[/tex] is in the interval [tex](0,90)[/tex], then [tex]\sin(A)>0[/tex].

[tex]\sin(A)=\sqrt{\frac{16}{25}}[/tex]

[tex]\sin(A)=\frac{\sqrt{16}}{\sqrt{25}}[/tex]

[tex]\sin(A)=\frac{4}{5}[/tex]

So let's finally find the numerical value of [tex]\sin(2A)[/tex].

[tex]\sin(2A)=2\sin(A)\cos(A)[/tex]

[tex]\sin(2A)=2\cdot \frac{4}{5} \cdot \frac{3}{5}[/tex]

[tex]\sin(2A)=\frac{2(4)(3)}{5(5)}[/tex]

[tex]\sin(2A)=\frac{24}{25}[/tex]

Side note:

If [tex]A[/tex] is between 0 and 90 degrees, then we are in the first quadrant.

If we are in the first quadrant, both [tex]x=\cos(A)[/tex] and [tex]y=\sin(A)[/tex] are positive.
