what are the relative minimum and relative maximum values over the interval [1, 5] for the function shown in the graph?

For a quadratic equation:

a*x^2 + b*x + c = 0

The quadratic formula is just:

[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac} }{2a}[/tex]

For a general quadratic equation:

a*x^2 + b*x + c = 0

The quadratic formula is:

[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac} }{2a}[/tex]

So for example, let's assume that we have the quadratic equation:

3x^2 + 7x - 12 = 0

Here we have the values:

a = 3

b = 7

c = -12

Now you could just replace them in the quadratic formula and you will get:

[tex]x = \frac{-7 \pm \sqrt{7^2 - 4*3*-12} }{2*3}[/tex]

And if you simplify that you will get the two solutions.

After answering the provided question, we can conclude that Option A (QR = SP) and Option B (QP = SR) by themselves are insufficient to demonstrate that PORS is a parallelogram. Option D (ZOPR = ZSRP).

In Euclidean geometry, a parallelogram is a simple quadrilateral with two sets of side lengths. A parallelogram is a type of quadrilateral in which both sets of opposite corners are similar and equal. Parallelograms are classified into four types, three of which are unique. The four different shapes are parallelograms, squares, geometric shapes, and rhombuses. A quadrilateral is a parallelogram when it has two sets of equal spacing. The opposing sides and angles of a parallelogram are both the same length. The interior angles on each side of the solid line are also angles. The total number of interior angles is 360.

Option C: The fact that V is the midpoint of PR suffices to demonstrate that PORS is a parallelogram.

We know that PV = VR because V is the midpoint of PR. Furthermore, because QR = SP (as shown in the drawing), we can conclude that triangles QRP.

We can deduce from this congruence that angle QRP is congruent to angle SPR, which means that angle POR is congruent to angle PSR (because they are corresponding angles). Angle OPS is also congruent with angle ORP (because they are corresponding angles).

Answer:

A=50 B=50 too C=180

The inverse function of p(x) = 50x - 400 is p⁻¹(x) = x/50 + 8.

Given the function in the question;

p(x) = 50x - 400

To determine the inverse, replace p(x) with y.

p(x) = 50x - 400

y = 50x - 400

Now, interchange the variables y and x.

x = 50y - 400

Solve for y

Add 400 to both sides

x + 400 = 50y - 400 + 400

x + 400 = 50y

Reorder the equation

50y = x + 400

Divide both sides by 50

50y/50 = x/50 + 400/50

y = x/50 + 400/50

y = x/50 + 8

Replace y with p⁻¹(x)

p⁻¹(x) = x/50 + 8.

Therefore, the inverse is  x/50 + 8.

The value of x in triangle HJK is 5 √2, So correct option is (A). The value of x in triangle ABC is 25√3, So correct option is (H).

The Pythagorean Theorem is a fundamental theorem in mathematics that relates the lengths of the sides of a right triangle. It states that in any right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Mathematically, the Pythagorean Theorem can be expressed as:

a² + b² = c²

where "a" and "b" are the lengths of the two sides of the right triangle and "c" is the length of the hypotenuse.

The Pythagorean Theorem is named after the ancient Greek mathematician Pythagoras, who is credited with its discovery. It is a widely used theorem in mathematics and has numerous applications in many fields, including geometry, trigonometry, engineering, physics, and computer graphics.

For example, in geometry, the Pythagorean Theorem can be used to find the distance between two points in two-dimensional space. In trigonometry, it can be used to find the sine, cosine, and tangent of an angle. In physics, it can be used to calculate the force required to accelerate an object, or to determine the velocity of an object at a given time.

Overall, the Pythagorean Theorem is an important theorem that provides a simple and elegant solution to many problems involving right triangles and is widely used in mathematics and science.

9. To find the value of x in triangle HJK, we can use the Pythagorean theorem. Let's call JK = x.

HK² + JK² = KH²

Since Angle HKJ is 60 degrees and Angle KHJ is 90 degrees, we can use the trigonometric ratios to find the length of HK:

HK = JK × tan 60 = JK / √3

Substituting this into the equation above, we get:

JK² / 3 + JK² = 5²

Expanding and solving for JK, we find that:

JK = 5 √2

So, the answer is (a) 5√2.

10. To find x in triangle ABC, we can use similar methods as in question 9. Let's call BC = x. Then, by the Pythagorean theorem, we have:

AC² + BC² = AB²

Since Angle BAC is 60 degrees and Angle ABC is 90 degrees, we can use the trigonometric ratios to find the length of AB:

AB = AC / √3

Substituting this into the equation above, we get:

AC² + BC² = (AC / √3)²

Expanding and solving for BC, we find that:

BC = AC * √3 / 2 = 50 × √3 / 2 = 25√3

So, the answer is (H) 25√3

The air speed of the plane to cover 360 miles against the wind and with the wind in the given time is equal to 200 miles per hour.

Let 'x' be the speed of the plane fly in still air.

And 'y' be the speed of the wind.

Speed against the wind = x - y

Speed with the wind = x + y

Total distance covered by plane = 360 miles

Time taken against the wind = 2 hours 15 minutes

                                               = 2 ( 1/4 ) hours

                                               = 9 / 4 hours

Time taken with the wind = 1 hour 30 minutes

                                          = 1 ( 1/2 ) hours

                                          = 3 /2 hours

Speed = distance / time

Against the wind :

x - y = 360 / (9 /4 )

⇒x - y = 160___(1)

With the wind:

x + y = 360 / (3 /2)

⇒x + y = 240 ___(2)

Add (1) and (2) we get,

2x = 400

⇒ x= 200miles per hour

⇒y = 40 miles per hour

Therefore, the air speed of the plane as per given condition is equal to 200miles per hour.

Answer:20x^8+28

Step-by-step explanation:multiply both terms by 4

Answer:

Step-by-step explanation:

Let's start by calculating the distance traveled in the first scenario:

Distance = Average speed x time

First, we need to convert 2 hours and 45 minutes to hours. There are 60 minutes in an hour, so 45 minutes is equal to 45/60 = 0.75 hours. Therefore, the total time is:

2 hours and 45 minutes = 2 + 0.75 = 2.75 hours

Now we can calculate the distance:

Distance = 106 km/h x 2.75 hours = 291.5 km

So the car travels 291.5 km in 2 hours and 45 minutes.

To find the constant speed the car must drive to travel the same distance in 2 hours and 35 minutes, we can use the same formula:

Distance = Speed x time

We know the distance is 291.5 km, and the time is 2 hours and 35 minutes. Again, we need to convert the minutes to hours:

2 hours and 35 minutes = 2 + 35/60 = 2.583 hours

Now we can solve for the speed:

Speed = Distance / time = 291.5 km / 2.583 hours ≈ 113 km/h

Therefore, the car must drive at a constant speed of approximately 113 km/h to travel the same distance in 2 hours and 35 minutes.

The value of VT is 13 units and the value of ST is 23.56 units

Consider the following diagram of rectangle RSTU

We know that the diagonals of rectangle bisect each other, intersect at right angles.

For rectangle RSTU,

2RV = RT

But RT = US

So, 2RV = US

2(x + 6) = 5x - 9

2x + 12 = 5x - 9

12 + 9 = 5x - 2x

3x = 21

x = 7

So, RV = 7 + 6

RV = 13 units

But RV = VT

So, VT = 13

Now we find the value of ST using Pythagoras theorem.

RT² = ST² + RS²

ST = [tex]\sqrt{RT^2 - RS^2}[/tex]

ST = 23.56 units

Thus, VT = 13 and ST = 23.56

If what you are looking for is( f/g) (x), then only place the value of f(x) as the quantifier and g(x) as the denominator. Then the function that satisfies is D.

But here there is a condition that (f/g) (x) applies if the value of x is not √5 or -√5. Because if it becomes an x value then the result will be 0.

We can prove this:

With this equation (f/g) (x)=4x+1/x²-5

let's try to use value of x is √5, it will be

(f/g) (x)=4x+1/x²-5

(f/g) (√5) = 4.√5+1/(√5)²-5
