1) The table shows the height in centimeters, that a weight bouncing from a spring would achieve if there were no friction, for a given number of seconds.
From it's resting position, how long does it take the weight to bounce one direction, then the other, and then back to it's resting position?
Answers
Answer:
The graph shows that a consistent time to go from resting position to point A, then back to resting, then to point B, then back to resting, and so on is 0.75 seconds.
To bounce from resting to point A then point B and back to resting is 3 seconds.
The question pertains to the period of oscillation in a simple harmonic motion scenario involving a weight and a spring. The period is calculated using the formula T = 2π√(m/k). The student asks how long it takes for the weight to complete one full oscillation cycle, which can be calculated using mass and spring constant.
Explanation:The students asked about the period of oscillation for a weight attached to a spring. In physics, especially concerning simple harmonic motion (SHM), the period is the time it takes for one full cycle of motion: moving in one direction, reversing, and returning to the starting point. To find the period of a mass-spring system, we use the formula T = 2π√(m/k), where T is the period, m is the mass, and k is the spring constant. This formula is derived from the motion equations that describe SHM.
For example, if you have a mass of 0.750 kg attached to a spring with a spring constant of 150 N/m, you would calculate the period using the mass (m) and the spring constant (k) from Hooke's Law. Similarly, when a spring exerts an upward force of 2.00 mg at the lowest point, this is due to the spring force being equal to the gravitational force at that point (mg) and also providing the restoring force needed for SHM (another mg).
Understanding SHM and its principles such as spring constant, and force of gravity are critical in solving these types of physics problems. These concepts explain how an attached weight on a spring moves in the absence of friction and other forces, such as air resistance.

If it takes 930 kg of food to feed a pair of elephants for 3 days how much food would u need to feed them for a week?
Answers
Steps:
Divide 930 by 3 to see how much food per day
Then multiply by 7 to see how much food needed for a week
Answer:
2170 kg
Step-by-step explanation:
since there are 7 days in a week first you calculate the days
930 plus 930 equals 1860 which can feed a pair of elephants for 6 days
then since in one day it takes 310 kg then add 1860 plus 310
and then you get 2170
so, you need 2170 kg of food to feed a pair of elephants in a week

there are 10 triangle therefore 106.48 x 10 = 1064.8
Answer:
532.4 in²
Step-by-step explanation:
The area (A) of the regular pentagon is calculated as
A = 0.5 × perimeter × apothem
Perimeter = 5 × 17.6 = 88 in
The apothem is the segment from the centre to the midpoint of one of the sides.
Here the apothem = 12.1 in, thus
A = 0.5 × 88 × 12.1 = 44 × 12.1 = 532.4 in²

Answers
Answer:
[tex]x=29[/tex]
Step-by-step explanation:
Given equation :
[tex]\frac{(7+2x)}{5} =13[/tex]
Making the terms of 'x' to one side and constants to the other.
[tex](7+2x)=13*5[/tex]
[tex]7+2x=65[/tex]
[tex]2x=65-7[/tex]
[tex]2x=58[/tex]
[tex]x=\frac{58}{2}[/tex]
[tex]x=29[/tex]
So, the value of 'x' is 29.
Answer:
x = 29
Explanation:
7 + 2x / 5 = 13
Multiply both sides by 5
7 + 2x / 5 = 13 · (5) = (13) · (5)
7 + 2x = 65
Simplify both sides of the equation
2x + 7 = 65
Subtract 7 from both sides
2x + 7 − 7 = 65 − 7
2x = 58
Divide both sides by 2
2x / 2 = 58 / 2
x = 29

The angle measure of m∠ACB (x°) is 39°.
Step-by-step explanation:
Let us name the joining points as ABC and ABC forms triangle with extended lines. (refer the image)
We have to find the value of m∠ACB = x°.
the given data,
m∠A=68°.
m∠B =107°.
To find m∠CAB,
Let us consider that AB is a line traversed by a line C intersecting at A. (refer diagram)
Using the theorem of corresponding angles theorem, when a line intersects another line, then the angles opposite each other is equal to each other.
m∠A=m∠CAB.
m∠CAB =68°.
To find m∠ABC,
Let us consider AB is a line.(refer diagram)
Using the straight line proof, the total of angles in a straight line is 180°.
Thus m∠ABC+m∠B=180°.
m∠ABC+107°=180°.
m∠ABC=180°-107°.
m∠ABC=73°.
Finally we have to find the value of x° that is m∠ACB.
Using the interior angles proof, the sum of interior angles of triangle is 180°.
⇒m∠ABC+m∠CAB+m∠ACB=180°.
73°+68°+m∠ACB=180°.
141°+m∠ACB=180°..
m∠ACB=180°-141°.
m∠ACB=39°.
Thus the angle measure of m∠ACB (x°) is 39°.

Answer:
Mean for Bakery A because the data is symmetric; median for Bakery B because the data is not symmetric, as can be observed from the stem and leaf frequency plot.
Step-by-step explanation:
CALCULATIONS FOR BAKERY A
Considering the data for Bakery A
45 52 51 48 57 30 55 46
Calculating Mean for Bakery A
[tex]Mean=\frac{Sum\:of\:terms}{Number\:of\:terms}[/tex]
Sum of terms = 45 + 52 + 51 + 48 + 57 + 30 + 55 + 46 = 384
Number of terms = 8
As
[tex]Mean=\frac{Sum\:of\:terms}{Number\:of\:terms}[/tex]
[tex]Mean=\frac{302}{8}[/tex]
[tex]Mean=48[/tex]
Calculating Median for Bakery A
As the median is the middle number in a sorted list of numbers. So, to find the median, we need to place the numbers in value order and find the middle number.
As the data for Bakery A is
45 52 51 48 57 30 55 46
Ordering the data from least to greatest, we get:
30 45 46 48 51 52 55 57
As you can see, we do not have just one middle number but we have a pair of middle numbers, so the median is the average of these two numbers:
[tex]Median=\frac{\left(48+51\right)}{2}=\frac{99}{2}=49.5[/tex]
Getting a Plot and Leaf Plot for Bakery A
Plot and leaf plot is generally a unique table-like diagram which displays the frequency distribution of a data set. Plot and leaf plot is a visual aid that supports us in recognizing frequency classes and the center of the distribution where most of the data gets clustered around.Data for Bakery A in ascending order

Perpendicular to 3y=x-4 and passes through the point (-2,1)
Answers
Answer:
The equation is [tex]y=-3x-5[/tex]
Step-by-step explanation:
We are given;
The equation of a line 3y = x-4 A point (-2,1)Assuming the question requires we determine the equation of a line perpendicular to the given line and passing through the point given.
Step 1: Determine the slope of the given line
To determine the slope from an equation requires we write the equation in the form, y = mx + c, where m will be the gradient.
In this case;
[tex]3y = x - 4\\ y = \frac{1}{3}x-\frac{4}{3}[/tex]
Therefore, the slope is [tex]\frac{1}{3}[/tex]
Step 3: Determine the slope of the line in question
We know that the product of the slope of two perpendicular line is -1
That is;
m₁ × m₂=-1
Thus;
1/3 × m₂ -1
Hence; m₂ = -3
Step 3: Determine the equation of the line in question;
We have its slope, m₂ = -3
A point (-2, 1)
Taking another point (x,y)
Thus;
[tex]\frac{y-1}{x--2}=-3\\y-1 =-3(x+2)\\y-1 = -3x-6\\y=-3x-5[/tex]
Therefore, the required equation is [tex]y=-3x-5[/tex]
The equation of the line perpendicular to the line and passing through the point is y = -3x - 5
Equation of a lineGiven the equation 3y = x - 4
Find the slope of the line
y = 1/3 x - 4/3
The slope of the line is 1/3 and the slope of the line perpendicular is -3
Substitute the point (-2, 1) and the slope into equation
y - y1 = m(x-x1)
y - 1 = -3(x+2)
y - 1 = -3x - 6
y = -3x - 5
Hence the equation of the line perpendicular to the line and passing through the point is y = -3x - 5

The sum of two numbers is zero. When 13 times the smaller number is added to 8 times the larger, the result is 2. Find the two numbers.
Answers
Answer:
x = (2/5); y = (-2/5)
Step-by-step explanation:
x + y = 0
13x + 8y = 2
Multiply so the "x" variables are opposite with the same absolute value.
(-13) x + y = 0 (-13) ⇒ -13x - 13y = 0
(1) 13x + 8y = 2 (1) ⇒ 13x + 8y = 2
Add the two equations.
(13x - 13x) + (8y - 13y) = (2 - 0)
-5y = 2
Divide both sides by -5
y = [tex]-\frac{2}{5}[/tex]
Plug the value of "y" into either equations.
x + [tex](-\frac{2}{5})[/tex] = 0
Add [tex]\frac{2}{5}[/tex] to both sides.
x = [tex]\frac{2}{5}[/tex]

A portrait without its frame has a height 1.5 times its width w, in inches. Its frame is 2 in. wide all along its perimeter. What is an expression for the area of
the framed portrait in terms of w?
A. 1.5W2 + 5W + 4
B. 1.5w2 + 8w + 8
C. 1.5w2 + 8.5w + 16
D. 1.5w2 + 10w + 16
Answers
Answer:
The correct answer is A. 1.5w² + 5w + 4
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Height of the portrait = 1.5 times its width in inches
Frame = 2 inches all along its perimeter
2. What is an expression for the area of the framed portrait in terms of w?
Let's recall that the area of a rectangle is length or height * width.
A = height * width
Now, we can replace in terms of w:
A = 1.5w * w
But we need to add the 2 inches of the frame, this way:
A = (1.5w + 2) * (w + 2)
A = 1.5w² + 2w + 3w + 4
A = 1.5w² + 5w + 4
The correct answer is A. 1.5w² + 5w + 4
Final answer:
The expression for the area of the framed portrait in terms of w is 1.5w^2 + 8w + 8.
Explanation:
To find the expression for the area of the framed portrait, we need to consider the dimensions of both the portrait and the frame. Let's assume the width of the portrait is w inches. According to the given information, the height of the portrait without the frame is 1.5 times the width, so the height is 1.5w inches.
To calculate the dimensions of the framed portrait, we need to add 2 inches to the width and height for the frame. The width of the framed portrait is w + 2 inches, and the height is 1.5w + 2 inches.
The area of the framed portrait is equal to the product of its width and height. Therefore, the expression for the area, in terms of w, is (w + 2) * (1.5w + 2). When we simplify this expression, we get 1.5w2 + 8w + 8.

A building in a city has a rectangle base. The length of the base measures 70 feet less than three times the width. The perimeter of this base is 900 feet. What are the dimensions of the base?
Answers
Answer:
Width 130 ft and
Length 320 ft
Step-by-step explanation:
We are given;
Length of the rectangular base is 70 ft less than three times the width;Perimeter of the rectangular base is 900 ftWe are required to determine the dimensions of the rectangular base;
Assuming the width of the rectangular base is x ft
Then length will be (3x - 70) ft
But;
Perimeter = 2L + 2W
Thus;
900 ft = 2(3x-70) + 2(x)
900 ft = 6x -140 +2x
1040 = 8x
x = 130
Thus;
Width = 130 ft
Length = 3x -70 = 320 ft
Hence the dimensions of the rectangular base are width 130 ft and length 320 ft
