Answer:
domain: (-infinity,infinity);
range: f(x)>= 0
Step-by-step explanation:
f(x) = 2|x – 4|
The domain is the input values or the values that x can take
We can use any value we want for x
Domain: -infinity to infinity
The range is the output values
Since it is an absolute value, the smallest value it can take is 0, it can increase as large as it wants
Range: 0, infinity

What is the volume of this container
Answer:
1,875 cm^3
Step-by-step explanation:
To find the volume of the big square you would multiply 20x5x20= 2,000
to find the volume of the little square you would multiply 5x5x5= 125
Then to find the Volume of the square with the hole in it you would subtract 2,000 and 125 which = 1,875 cm^3
A car is moving at a constant acceleration of 7.0 m/s/s. How fast (velocity) is it going after 4.0 seconds, if it starts from rest.? Show work using ESA format.
28 m/s is the velocity , when it is going after 4.0 seconds.
What is Acceleration?When a point or an object moving in a straight line , the acceleration is the rate at which velocity changes with time, in terms of both speed and direction.
Here, given that,
A car is moving at a constant acceleration of 7.0 m/s/s
Now, we have,
Velocity = acceleration * time
After 4 sec. = 7*4 = 28 m/s
Hence, 28 m/s is the velocity , when it is going after 4.0 seconds.

Help Plz! Sam has to read a 144-page book for his literature class.He has 8 days to finish it.He wants to read about the same number of pages each day.How many pages per day must he read to finish the book in 8 days?
Answer:
18 pages per day
Step-by-step explanation:
Take the number of pages in the book and divide by the number of days he has to read to determine the number of pages per day
144/8 =18 pages per day
Add.
(8y + 6) + (4y + 5)
Submit
Answer:
12y + 11
Step-by-step explanation:
To add them you would add like terms. That means you would add those with y together and those without together.
8y + 4y + 6 + 5 = 12y + 11
If you want to solve for y, subtract 11 from both sides then divide both sides by 12.
Answer:
Step-by-step explanation:
hello :
(8y + 6) + (4y + 5)=12y+11
What is the median of the following data 2,3,1,1,0,4
Answer:
1.5
Step-by-step explanation:
0,1,1,2,3,4 - rearrange in order
2+1=3
3/2=1.5
I hope this helps!
Answer:
1.5
Step-by-step explanation:
Arrange the data in order from least to greatest
2,3,1,1,0,4
Least to greatest:
0,1,1,2,3,4
Then, find the number in the middle
In this case, there is 2 numbers in the middle, so we will take the average of those 2
1,2
To find the average, add up the numbers and divide by the number of terms
1+2=3
3/2=1.5

A water bottle rocket is shot upward with an initial velocity of vi = 40 ft/s from the roof of a school, which is at hi = 70 ft above the ground. The equation h = −
1
2
at2 + vit + hi models the rocket's height as a function of time. The acceleration due to gravity a is 32 ft/s2.
We are to find how long will it take to return to the ground?
Answer:
t = 0.48 sec
Step-by-step explanation:
We are given;
initial velocity; vi = 40 ft/s
hi = 70 ft
acceleration due to gravity; a = 32 ft/s²
Now, we are given that the rocket's height as a function of time is;
h = -12at² + vit + hi
At ground, h = 0
Plugging in the relevant values to obtain ;
0 = -12(32)t² + 40t + 70
-384t² + 40t + 70 = 0
The roots of the equation gives; t = 0.48 sec

What is the polynomial function of lowest degree with leading coefficient of 1 and roots 2 and 1+
2?
f(x)= x2 – 2x-1
f(x)=x2 - 4x2 + 2x +2
f(x)= x° - 4x2 + 3x + 2
f(x)= x2 + 2x-1
Answer:
f(x)=x2 - 4x2 + 2x +2
Step-by-step explanation:

which choice correctly shows the solution(s) of the equation x2=121?
Answer:
x = ±11
Step-by-step explanation:
x^2 =121
Take the square root of each side
sqrt(x^2) = ±sqrt(121)
x = ±11
Answer:
x=±11
Step-by-step explanation:
To solve, we need to isolate the variable x,
To do this, take the square root of both sides
[tex]x^{2} =121\\\sqrt{x^{2} } =\sqrt{121}[/tex]
x=±11
It is positive or negative 11 because 11^2 (11*11)=121, but -11^2 (-11*-11) also equals 121 because 2 negatives multiplied become a positive.
The length of the shortest side of a 30-60-90 triangle is 2 cm. Which of the following is the length of the hypotenuse?
2cm
√3cm
4cm
2 √3cm
Answer:
4 cm
Step-by-step explanation:
The ratios of sides in a 30-60-90 triangle are ...
1 : √3 : 2
The hypotenuse is double the length of the shortest side, so is 4 cm in your triangle.
Final answer:
In a 30-60-90 triangle, if the shortest side is 2 cm, the hypotenuse is twice that length, resulting in a hypotenuse of 4 cm.
Explanation:
The 30-60-90 right triangle has sides in a specific ratio. The lengths of the sides opposite the 30°, 60°, and 90° angles are in the ratio 1:√3:2. If the shortest side is 2 cm, which is opposite the 30° angle, the hypotenuse is twice the length of the shortest side because it is opposite the 90° angle. Therefore, the length of the hypotenuse is 4 cm.
Which of the following is a property of all squares?
A
No sides are parallel.
B
Opposite sides are not congruent.
C
Opposite vertex angles are not congruent.
D
The diagonals bisect each other.
Answer:
D. the diagonals bisect each other
Final answer:
The property of all squares is that their diagonals bisect each other. Other options are incorrect as squares have parallel and congruent sides as well as congruent angles. Therefore, the correct answer is D.
Explanation:
The question asks which of the following is a property of all squares. The correct answer is option D: The diagonals bisect each other. In every square, this property holds true, as squares are a type of rectangle, and in rectangles, the diagonals are congruent and bisect each other. We know that a square has four equal sides and four equal angles, which are right angles.
This implies that not only are the diagonals congruent, but they also divide the square into four congruent right triangles, bisecting one another at their midpoint. Options A, B, and C describe properties that are incorrect for squares, as all sides of a square are parallel and congruent, and all angles are congruent as well.

how much wrapping paper would you need to cover a rectangular that is 18.25 inches by 12inches by 3 inches if you need 10% more wrapping paper than the surface area of the box? give your answer to the nearest square inch
Answer: 681 square inch
Step-by-step explanation:
Hi, we have to apply the formula for the surface area:
A = 2wl + 2lh + 2hw
Where:
w: width
l: length
h: height
Replacing with the values given:
A = (2x12x18.25) + (2x12x3)+(2x18.25x3)
A= 438+72+109.25
A=619.5 in2
Since it has to be 10% more than the surface.
619.5 x (10/100) = 61.95 in2
Adding that value to the surface area
619.5+61.95 = 681.45in2 = 681 in2

Evaluate each logarithm. Round your answer to the nearest ten thousandth.
1. Log5 15
2. -3ln(1/e4/5)
Answer:
1. 1.685
2. 16.828
Step-by-step explanation:
1. log_5 15
To evaluate this logarithm you use the following formula:
[tex]Log_ab=\frac{log_{10}b}{log_{10} a}[/tex]
by replacing you obtain:
[tex]log_5 15=\frac{log_{10} 15}{log_{10}5}=\frac{1.176}{0.698}=1.685[/tex]
hence, the answer is 1.685
2. -3ln(1/e4/5)
to solve this logarithm you use the following properties:
[tex]ln(a^m)=m\ ln(a)\\\\ln(\frac{a}{b})=ln(a)-ln(b)\\\\ln(e^m)=m[/tex]
[tex]ln(1)=0[/tex]
By applying all these properties you obtain:
[tex]-3ln(\frac{1}{\frac{e^4}{5}})=-3[ln(\frac{1}{e^4})-ln(5)]=-3[ln(1)-ln(e^4)-ln(5)]\\\\-3ln(\frac{1}{\frac{e^4}{5}})=-3[0-4-1.609]=16.828[/tex]
hence, the answer is 16.282
Find the value of x in the figure
Answer:
x=85
Step-by-step explanation:
The angles are vertical angles, therefore they are congruent. This means we can set them equal to each other.
x+5=90
Solve for x by isolating x. To do this, subtract 5 from both sides
x+5-5=90-5
x=85
So, x=85, and the second choice is correct.
Answer:
It is 85.
Step-by-step explanation:
The angles are vertical from each other so they are equal. 85+5=90.
