Comparing a hatchling turtle's shell of 1-inch diameter to a 4-inch diameter shell reveals that the volume increases by a factor of about 64, while the surface area only increases by about 16. This difference is due to the way volume and surface area are calculated, with the radius being cubed in the volume formula and squared in the surface area formula.
Explanation:The volume of a sphere (like the turtle's shell) is given by the formula: V = (4/3) * π * r³, and the surface area by A = 4 * π * r², where r is its radius. If a hatchling turtle's shell has a 1-inch diameter, it has a radius of 0.5-inches. If as the turtle grows, its diameter expands to 4-inches, then the radius will be 2-inches. As the radius in each formula is cubed in the volume formula and squared in the surface area formula, the volume will increase far more rapidly than the surface area.
For the smaller turtle, V = (4/3)*π*(0.5)³ = 0.52 cubic inches and A = 4*π*(0.5)² = 3.14 square inches. For the larger turtle, V = (4/3)*π*(2)³ = 33.51 cubic inches and A = 4*π*(2)² = 50.27 square inches. Comparing, the volume increases by a factor of 64 (33.51/0.52) whereas the surface area increases by a factor of roughly 16 (50.27/3.14). This shows that although the turtle's shell maintains the same shape as it grows, the volume increases significantly more than the surface area.

The coordinates of point A on a grid are (2, -5). Point A is reflected across the x-axis to obtain point B. The coordinates of point B are (2, ___). (1 point)
Answer:
(2,5)
Step-by-step explanation:
If you are flipping a point over the x-axis, multiply the y coordinate by -1, if you are flipping something over the y-axis, multiply the x coordinate by -1.
The coordinates of point B are (2,5)
How does reflection across axis work?When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.
If you study it more, you will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.
Given that coordinates of point A on a grid are (2, -5). Point A is reflected across the x-axis to obtain point B.
Since flipping a point over the x-axis, then we have to multiply the y coordinate by -1,
And ifyou are flipping something over the y-axis, then we have to multiply the x coordinate by -1.
Therefore, the point B are (2, _5_).

These box plots represent the number of seconds that a random sample of 100 traffic lights are red in each of two cities: Johnstown and Martinville
Answer:
The question is not complete. Attached to this answer is the diagram of the box plot and the complete question:
These box plots represent the number of seconds that a random sample of 100 traffic lights are red in each of two cities: Johnstown and Martinville
Based on the data on the two box plots, which statement about the difference in the medians of the two data sets is true?
The correct answer is:
The difference is about [tex]\frac{1}{2}[/tex] times the range of the data shown for Johnstown,and about [tex]\frac{3}{8}[/tex] times the range of data for Martinville. (D)
Step-by-step explanation:
From the box plot, it is seen that the following data can be gotten:
Cities Range Midian (mid-point)
Johnston 140 - 80 = 60 110
Martinville 120 - 40 = 80 80
Difference in medians = 110 - 80 = 30
now comparing the difference between the median and the ranges of each city, we observe that:
range for Johnston = 60 ; median difference = 30
hence difference in medians : range for Johnston = 30 : 60 = 1 : 2 = 1/2
hence difference of medians is [tex]\frac{1}{2}[/tex] times the range of Johnston.
Difference of midians : range of Martinville = 30 : 80 = 3 : 8 = 3/8
hence the difference of medians is [tex]\frac{3}{8}[/tex] times the range of Martinville.

Based on the data on the two box plots, which statement about the difference in the medians of the two data sets is true?
The correct answer is:
The difference is about times the range of the data shown for Johnstown,and about times the range of data for Martinville. (D)
Step-by-step explanation:
From the box plot, it is seen that the following data can be gotten:
Cities Range Midian (mid-point)
Johnston 140 - 80 = 60 110
Martinville 120 - 40 = 80 80
Difference in medians = 110 - 80 = 30
now comparing the difference between the median and the ranges of each city, we observe that:
range for Johnston = 60 ; median difference = 30
hence difference in medians : range for Johnston = 30 : 60 = 1 : 2 = 1/2
hence difference of medians is times the range of Johnston.
Difference of midians : range of Martinville = 30 : 80 = 3 : 8 = 3/8
hence the difference of medians is times the range of Martinville.

Jane is training for a triathlon. After swimming a few laps, she leaves the health club and bikes 24 miles south. She then runs 10 miles west. Her trainer bikes from the health club to meet jane at the end of her run. How much farther does jane travel than her trainer?
Answer:
26 miles farther from her trainer
Step-by-step explanation:
She starts her journey at health club,
Ran 24 miles south and then 10 miles west.
The distance between her end point and her trainer who was at health club can be calculated using pythagorean theorem.
X² = y² + z²
X = her end point
Z = distance between health club 24 miles south. = 24miles
Y = 10 miles distance from the 24 miles south. = 10 miles.
(See attachment for better illustration.)
X² = 24² + 10²
X² = 576 + 100
X² = 676
X = √(676)
X = 26 miles
Jane was 26 miles farther from her trainer

An object is launched at 29.4 meters per
second (m/s) from a 34.3-meter tall
platform. The equation for the object's
height s at time x seconds after launch is
f(x) = -4.9x2 + 29.4x+ 34.3, where y is in
meters. What is the initial height of the
object?
29.4 meters
78.4 meters
34.3 meters
3 meters
Answer:
34.3 meters
Step-by-step explanation:
The generic equation for a movement with constant acceleration is:
S = So + Vo*t + (a*t^2)/2
Where S is the final position, So is the inicial position, Vo is the inicial speed, a is the acceleration and t is the time.
If we compare with our equation (where x is the time and f(x) is the final distance), we have that:
So = 34.3
Vo = 29.4
a = -9.8
So we have that the inicial position (So) of the object is 34.3 meters
