What is the range of the function f(x)=(x-1)^2 when the domain is {-5,0,5}?

Step-by-step explanation:

The highest point of a parabola is at the vertex.

x = -b / (2a)

x = -1 / (2×-0.0023)

x ≈ 217.4

y = (217.4) − 0.0023 (217.4)²

y ≈ 108.7

The horizontal distance can be found when the potato lands (y=0):

0 = x − 0.0023x²

0 = x (1 − 0.0023x)

x = 0, x ≈ 434.8

So the potato reaches a maximum height of 108.7 m and travels a horizontal distance of 434.8 m.

The height point of the trajectory is 217.39 meters and the horizontal distance the potato travels before hitting the ground is 434.78 meters.

To find the height point of the trajectory and the horizontal distance the potato travels before hitting the ground, we can use the equation y=x-0.0023x^2 to represent the trajectory. Since the trajectory is a parabola, the height point corresponds to the vertex of the parabola. To find the vertex, we can use the formula x = -b / (2a), where a = -0.0023 and b = 1. To find the horizontal distance the potato travels before hitting the ground, we need to find the x-intercepts of the parabola, which correspond to the points where y = 0.

First, let's find the height point:

Using the formula x = -b / (2a) and substituting the values, we get:

x = -1 / (2 * (-0.0023)) = 217.39 meters

Now, let's find the horizontal distance:

Setting y = 0 and solving for x, we get:

0 = x - 0.0023x^2

0 = x(1 - 0.0023x)

x = 0 or x = 434.78 meters

Therefore, the height point of the trajectory is 217.39 meters and the horizontal distance the potato travels before hitting the ground is 434.78 meters.

Answer:

None of the statements are true​

Step-by-step explanation:

Given statements are:

I. The difference between -14 and -8.3 is positive.

II. -14 + 8.3 has the same value as the difference between -1.4 and -8.3.

III. The between -8.3 and -14 has the same value as the difference between -1.4 and -8.3.

Test for statement (I).

difference = -14-(-8.3) = -14+8.3 = -5.7

which is negative so statement I is FALSE.

Test for statement (II).

-14+8.3 = 5.7

difference = -14-(-8.3) = -14+8.3 = -5.7

which are different so statement II is FALSE.

Test for statement (III).

difference = -8.3-(-14) = -8.3+14 = 5.7

which is different than difference value -5.7 for statement I.

so statement III is FALSE.

So the correct choice is "None of the statements are true​".

Answer:

The first blank is "y", the second blank is "x", and the third blank is 1:3.

The greatest common factor between 14 and 24 is 2 because

The factors of 14 that divides 14 without a remainder are 1,2, and 7

The factors of 24 that divides 14 without a remainder are 1,2,3,4,6,8,and 12

Therefore 2 is the greatest factor between 14 and 24.

For this case we have that by definition, the Greatest Common Factor or GFC of two numbers is given by the biggest factor that divides both without leaving residue. We should look for the GFC of 14 and 24.

14: 1,2,7,14

24: 1,2,3,4,6,8,12,24

Thus, it is observed that the GFC of both numbers is 2.

Answer:

485 ft

Step-by-step explanation:

step 1

Find the distance from the base of the building to the base of the radio tower

Let

x -----> the distance from the base of the building to the base of the radio

we know that

tan(36°)=254/x

x=254/tan(36°)=349.60 ft

step 2

Find the distance from the base of the tree to the base of the radio tower

Let

x -----> the distance from the base of the tree to the base of the radio tower  

we know that

tan(62°)=254/x

x=254/tan(62°)=135.05 ft

step 3

Find the distance from the base of the building to the base of the tree

Adds the distances

349.60 ft+135.05 ft=484.65 ft

Round to the nearest foot

484.65 ft=485 ft

The final distance is approximately 485 feet.

Calculating the Distance from the Building to the Tree

To determine the distance from the base of the building to the base of the tree given the angles of elevation to the top of the radio tower, we can use trigonometry.

Let the height of the radio tower be 254 feet. Assume the distance from the base of the building to the base of the tower is x feet, and the distance from the base of the tree to the base of the tower is y feet.

Step-by-Step Solution:

Using the angle of elevation from the building, 36°, we can write:

tan(36°) = 254 ÷ x

Solving for x: x = 254 / tan(36°)

Using the angle of elevation from the tree, 62°, we can write:

tan(62°) = 254 ÷ y

Solving for y: y = 254 / tan(62°)

Calculate the values:

tan(36°) ≈ 0.7265

x = 254 / 0.7265 ≈ 349.6 feet.

tan(62°) ≈ 1.8807

y = 254 ÷ 1.8807 ≈ 135.1 feet.

The total distance from the base of the building to the base of the tree is x + y:

Total distance = 349.6 + 135.1 ≈ 485 feet.

Thus, the distance from the base of the building to the base of the tree is approximately 485 feet.

Electrical power is the rate at which the electrical force does work. So what is electrical work? That's the work [tex]W[/tex] that the electrical force do when it moves charges [tex]Q[/tex] across a potential difference [tex]V[/tex]:

W = [tex]V\cdot Q[/tex].

The power is the rate at which the electrical force do the work:

Answer:

The value of y when x = 5 and z = 16 is 272

Step-by-step explanation:

* Lets Talk about the direct variation

- y is varies jointly (directly) as x and z, that means there are direct

  relation between y , x and z

- y increases if x increases or z increases

∴ y ∝ x × z

- To change this relation to equation we use a constant k

∴ y = k (x) (z), where k is the constant of variation

- To find the value of k we substitute the values of x , y and z in

  the equation above

∵ y = 136 when x = 5 and z = 8

∴ 136 = k × 5 × 8

∴ 136 = 40 k ⇒ divide both sides by 40

∴ k = 3.4

- Substitute this value in the equation

∴ y = 3.4 (x) (z)

∵ x = 5 , z = 16

∴ y = 3.4 (5) (16) = 272

∴ The value of y when x = 5 and z = 16 is 272

Answer:

The correct answer is B.

Step-by-step explanation:

If y varies jointly as x and z, then we can write the join variation equation.

[tex]y=kxz[/tex], where 'k' is the constant of proportionality.

If y = 136 when x = 5 and z = 8,then

[tex]136=k(5)(8)[/tex],

[tex]\implies 136=40k[/tex]

[tex]\implies \frac{136}{40}=k[/tex]

[tex]\implies \frac{17}{5}=k[/tex].

The variation equation now becomes:

[tex]y=\frac{17}{5}xz[/tex]

when x = 5 and z = 16, then

[tex]y=\frac{17}{5}(5)(16)[/tex]

[tex]y=17(16)[/tex]

[tex]y=272[/tex]

The correct answer is B.

The zeros of the function f(x) = 3x^2 - 24x + 36 are found using the quadratic formula to be x = 6 and x = 2.

The zeros of the function f(x) = 3x2 \- 24x + 36 are the values of x for which f(x) equals zero. To find the zeros, we set the quadratic equation equal to zero and solve for x. This can be done using the quadratic formula x = (-b \\pm (sqrt{b2 \(- 4ac})/(2a), where a = 3, b = -24, and c = 36. Applying the quadratic formula:

Therefore, the zeros of the function are x = 6 and x = 2.

The value of 's' is calculated using the formula s = re, where e is the angle in radians and r is the radius in meters, which can also be determined statistically.

The value of s in the given physics problem represents the distance between two objects separated by an angle, when they are a certain distance r apart. According to the information and by using the formula s = re, where e is the angle in radians and r is the radius in meters (converted from millimeters), we can substitute the known values to find s. Since S = 80×109 N/m² is the shear modulus and given the small value of Kåp, we assume that s will be significantly small compared to 0.040. Additionally, the value of s can also be found using statistical methods, as indicated by a computer or calculator output showing s = 16.4 as the standard deviation in a set of residuals.

Complex numbers exist the numbers that exist expressed in the form of a+ib where, a, and b are real numbers, and 'i' exists an imaginary number named “iota”. The value of i = (√-1).

The abbreviated polar form of a complex number exists z = rcis θ, where r = √(x2 + y2) and θ = tan-1 (y/x).

The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number in the distribution from the highest.

The range in statistics for a given data set is the difference between the highest and lowest values. For example, if the given data set is {2,5,8,10,3}, then the range will be 10 – 2 = 8.
