the graph shows the depth,y, in meters, if a shark from the surface of an ocean for a certain amount of time, x, in minutes:
part a: describe how you can use similar triangles to explain why the slope of the graph between points a and b is the same as the slope of the graph between points a and c?
part b: what are the initial value and slope of the graph, and what do they represent?
Answer: Look at the step-by-step
Step-by-step explanation:
Part A: We can use two right triangles that represent rise over run to explain the slope of points A and B which has the same slope of points A and C. Since there will be two right triangles, they are considered similar triangles.
AB: 154 - 110= 44
44/2= 22
AC: 154 - 66 = 88
88/2=44
This means that the slope of the two sets of points is 44, and it represents the rate of change of the shark travelling away from the ocean’s surface every minute.
Part B: The initial value is 66 (m), and it represents the initial position of the shark at 0 minutes.
The equation of line is y = where y is the distance from ocean surface and x is the time taken in minutes , where the slope is m = 44 m/min
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the number of minutes be x
Let the distance from ocean surface be y
Let the first point be P ( 0 , 66 )
where P is the initial point of the graph
Let the second point be Q ( 2 , 110 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 110 - 66 ) / ( 2 - 1 )
Slope m = 44
And , the equation of line is
y - 66 = 44 ( x - 0 )
Adding 66 on both sides , we get
y = 44x + 66
Hence , the equation of line is y = 44x + 66

Where the above right triangle is given, note that the value of x when rounded to the nearest tenth is 19.2.
What is a right triangle?
A right triangle is a triangle with one angle measuring 90°, forming a perpendicular side.
In this case,the base is 9 and the height is 17. Using the Pythagorean theorem, we can calculate the length of the hypotenuse as follows:
x² = 9² + 17²
x²= 81 + 289
x² = 370
To find the value of x, we take the square root of both sides -
x = √370
x = 19.2353840617
x ≈ 19.2 (rounded to the nearest tenth)

There are 660 counters in a bag 1/6 of the counters are red 25% are blue and the rest are green how many green counters are there in a bag
Answer:
385 counters
Step-by-step explanation:
Since 1/6 of the counters are red and 1/4 of the counters are blue, there are:
1 - (1 / 6) - (1 / 4) = 7 / 12
Multiply it to find green:
660 x (7 / 12) = 385 counters

consider the graphs of the functions f(x)=10x and g(x)= log x. describe the relationship between these functions
Answer:
The functions are inverse functions. F is exponential and g is logarithmic.
Step-by-step explanation:
Answer:
Function f is an exponential function with a base of 10, and function g is a logarithmic function with a base of 10. These two functions are inverse functions. The values in the domain of function f are the values in the range of function g, and the values in the range of function f are the values in the domain of function g. The graph of function g is the graph of function f reflected over the line y=x The two functions have similar, but inverse, features. For example, function f has a horizontal asymptote of y=0 and crosses the y-axis at (0,1) while function g has a vertical asymptote at x=0 and crosses the x-axis at (1,0)

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that all of the middle school mathletes solve math problems at the same pace. Working together, 6 mathletes complete all of the summer homework in 22 hours.
6 mathletes complete all of the summer homework in 22 hours.
If the number of mathletes increases by a factor of 4, the number of mathletes will be (4 x 6) = 24 mathletes.
We can write -
1 mathlete will complete all of the summer homework in (22/6) hours.
24 mathlete will complete all of the summer homework in (22/6 x 24) hours.
(22/6 x 24)
(22 x 4)
88
Therefore, it will take 88 hours to complete the homework.

In order to solve the equation below, what would be a valid first step?
4(x+8) =34−2x
Answer:
multiply 4 and x and then multiply 4 and 8
Step-by-step explanation:
Answer: x=0.3
Step-by-step explanation:
you would write the equation again
4(x+8)=34-2x time 4 byx and the same on the other side
4x+32=34-2x get rid of the 2x by adding 2x
6x+32=34 get rid of 32 by doing opposite and taking away
6x=2 you want one x so divide by six on both sides
x=0.3
There were 200 members at a skating club. After some new members went in, there were 256 members altogether at the skating club. What was the percentage increase of members at the skating club?
the percentage increase of members at the skating club is 28%
What is relative change?"relative change = (final value - initial value)/ initial value"
What is percent change?percent change = relative change × 100
For given example,
There were 200 members at a skating club. After some new members went in, there were 256 members altogether at the skating club.
initial value (a) = 200
final value (b) = 256
So, relative increase is,
⇒ R = (b - a)/a
⇒ R = (256 - 200)/200
⇒ R = 56/200
⇒ R = 0.28
So, the percent increase is,
⇒ P = R × 100
⇒ P = 0.28 × 100
⇒ P = 28%
Therefore, the percentage increase of members at the skating club is 28%

Step-by-step explanation:
Formula for the area of a sector of central angle n (in degrees) and radius r:
[tex] A = \dfrac{n}{360^\circ}\pi r^2 [/tex]
We have:
A = 100 ft^2
r = 22 ft
We need to find:
r
[tex] 100 = \dfrac{n}{360^\circ}\pi (22^2) [/tex]
[tex] n = 23.7^\circ [/tex]
The central angle measures 23.7°.
Formula for the length of an arcs of a circle with central angle n (in degrees) and radius r:
[tex] s = \dfrac{n}{360^\circ}2 \pi r [/tex]
We have:
n = 23.7°
r = 22 ft
We need to find:
s
