The range of f(x) = |-x| is _____.

y < 0 , y > 0 , y ≤ 0 , y ≥ 0

Answers

Answer 1
This is an absolute value ,  for example |-6| = 6 and |-0| = 0  so your answer is

Y >= 0  ( your last choice)
Answer 2

Answer:

y ≥ 0

Step-by-step explanation:

The real absolute value function is defined on the set of all real numbers, assigning each real number its respective absolute value. Formally, the absolute value of any real number x, is defined by:

[tex]|x|=x,\hspace{3}if\hspace{3}x\geq0\\|x|=-x,\hspace{3}if\hspace{3}x<0[/tex]

The domain of the function is all real numbers, and by definition, the absolute value of x will always be greater than or equal to zero and never negative. Hence:

[tex]Domain:\\x\in R\\Range:\\y\in R : y\geq0[/tex]

mr scott rented a bicycle for 6 hours on saturday and then several more hours on sunday. it cost $4 per hour to rent the bicycle, and he paid a total of $48 For many hours did mr scott rented the bicycle on sunday

Answers

Final answer:

After calculating the cost for 6 hours of bicycle rental on Saturday, we subtracted that from the total cost to determine the cost for Sunday. By dividing this amount by the hourly rate, we concluded that Mr. Scott rented the bicycle for an additional 6 hours on Sunday.

Explanation:

The question asks how many hours Mr. Scott rented a bicycle on Sunday. To solve this, we need to calculate the total rental hours using the cost information provided. We know that Mr. Scott rented the bicycle for 6 hours on Saturday, and the rental cost is $4 per hour. He paid a total of $48 for the entire rental period over the two days.

First, let's calculate the cost for Saturday's rental: 6 hours × $4 per hour = $24. Now we know that Mr. Scott spent $24 on Saturday, so the remaining $24 ($48 total - $24 for Saturday) must have been spent on Sunday's rental. Dividing the remaining cost by the hourly rate gives us the number of hours rented on Sunday: $24 ÷ $4 per hour = 6 hours. Therefore, Mr. Scott rented the bicycle for 6 hours on Sunday as well.

If a cone has the same radius and height as a cylinder, the volume of the cone is

one-fourth one-third half two-thirds

the volume of the cylinder. If a cylinder and a sphere have the same radius and the cylinder’s height is twice its radius, then the volume of the sphere is

one-fourth one-third half two-thirds

the volume of the cylinder.

Answers

The answer to this question would be:
First problem= one-third
Second problem= two-third

To answer this question, you need to know the formula for cylinder volume, cone volume and sphere volume. The formula would be:

cylinder volume = π * r^2 * h 
cone volume= π * r^2 * h /3
sphere volume= 4/3 π r^3

From the first problem, the radius and height of the cylinder are same as the cone. Then the calculation would be:
cone volume / cylinder volume= (π * r^2 * h /3) / (π * r^2 * h)= 1/3
The first answer is one-third.


For the second problem, the radius of the cylinder and sphere is same, but the cylinder height is twice as it radius. Then the calculation would be:

volume of sphere / volume of cylinder= (4/3 * π * r^3) / (π * r^2 * h)
(4/3 * π * r^3) / (π * r^2 * 2r) =
(4/3 * π * r^3) / (2 * π * r^3 ) =
(4/3)/2= 4/6 = 2/3
Then the second answer is two-third

The volume of the cone is one-third the volume of the cylinder, if both shapes have the same radius and height

The volume of a cone is represented as:

v = 1/3[tex]\pi[/tex]r^2h

The volume of a cylinder is represented as:

V = [tex]\pi[/tex]r^2h

Substitute [tex]\pi[/tex]r^2h for V in the volume of the cone

v = 1/3V

The above means that:

The volume of the cone is one-third the volume of the cylinder

Answers

so Kim and her best friends are 10.6 miles away and we are trying to find out how many inches are they apart

10.6/5 = 2.12 
that equation represents how many miles away they are now we mulitply 
2.12x 2 to find a number of inches 4.24

Answer:

4.24 inches.

Step-by-step explanation:

In the map,

2 inches represents 5 miles,

Thus, we can write,

[tex]5\text{ miles}=2\text{ inches}[/tex]

[tex]1\text{ mile}=\frac{2}{5}\text{ inches}-----(1)[/tex]

Since, the actual distance between the two schools is 10.6 miles.

Multiplying both sides by 10.6 in equation (1),

[tex]10.6\text{ miles}=10.6\times \frac{2}{5}=\frac{21.2}{5}=4.24\text{ inches}[/tex]

Hence, the distance between the two schools in the map is 4.24 inches.

In triangle ΔABC, ∠C is a right angle and CD is the height to AB, Find the angles in ΔCBD and ΔCAD if: m∠A = α

m∠DBC =
m∠DCB =
m∠CDB =
m∠ACD =
m∠ADC =

Answers

Refer to the figure shown below.

Given:
m∠C = 90°, because ∠C is a right angle.
m∠D = 90°, because CD is the height to AB.
m∠A = α

Because the sum of angles in a triangle is 180°, therefore
m∠DBC + 90° + α = 180°
m∠DBC = 90° - α

Again, for the same reason,
m∠DCB + m∠DBC + 90° = 180°
m∠DCB + 90° - α + 90° = 180°
m∠DCB = α

For the same reason,
m∠ACD + 90° + α = 180°
m∠ACD = 90° - α

m∠ADC = 90° (by definition)
m∠CDB = 90° (by definition)

Answer:
m∠DBC = 90° - α
m∠DCB = α
m∠CDB = 90°
m∠ACD = 90° - α
m∠ADC = 90°

Maria gathered the data in the table. She finds the line of best fit to be y = 2.78x – 4.4. What is the residual value when x = 4?

Answers

The correct answer would be C.0.58

You plug 4 into the line of best fit and get 6.72. This is your predicted value, but the residual is the difference between the actual value and predicted. So you subtract: 7.3-6.72=0.58.

Solution:

The line of best fit is given as y=2.78x-4.4

We need to find the residual value when x=4.

The residual value is  an estimate of the wholesale value .To find the residual value we plug in x=4 in the given line of best fit.The corresponding y value will give the predicted  value.

y=2.78x-4.4

Substituting x=4,

y=2.78(4)-4.4

y=11.12-4

y=7.12.

The predicted value when x=4 is y=7.12.

Residual value = predicted value  - Actual value -=7.12 - actual value.

The sides of a triangle are of lengths 13, 14, 1nd 15. the altitude of the triangle meet at point h. if ad is the altitude to the side length 14, what is the ratio hd:ha

Answers

The ratio of HD:HA in a triangle with sides 13, 14, and 15, where AD is the altitude, is 13:14.

The question involves finding the ratio of lengths HD:HA in a triangle with sides of lengths 13, 14, and 15, where AD is the altitude to the side of length 14.

According to the given theorem, if we consider AD as the altitude ha from vertex A and HD as ht, we are informed that a:ht=b:ha, where a and b are sides of the triangle.

Since triangle ABC has sides a=13, b=14, and c=15, we apply the theorem such that 13:HD=14:HA.

This gives us the ratio HD:HA as 13:14. Therefore, for every 13 units of height from H to D, there are 14 units of height from H to A.
