The two figures are similar to find the ratios (shaded to non-shaded) of perimeters
Answers
perimeter of non-shaded part = 7
perimeter of shaded part = 9
so ratio of shaded to non shaded is =
shaded:non shaded = 9:7 = 9/7
so option b is correct
Answer:
I think it's 9/7 for the nonshaded one and the shaded one is 81/49
Step-by-step explanation: To be honest i'm using both division and multiplication that's really all ad hope I helped you out yo.

Answers
Answer: The answer is F.
Step-by-step explanation: It’s F because the number would be multiplied equally because all of the number are multiplied by 2. The rest of them either have variables or variables with numbers in them, which looks kind of funky, so F is the answer. I hope you get it right :).

What equation, in point-slope form, matches the graphed line shown?
Question 3 options:
y−5=−23(x+9)
y−6=45(x−2)
y−2=−34(x−6)
y+6=45(x+3)
Answers
Answer:
Here’s the graph
Step-by-step explanation:
The equation of the line in point-slope form that matches the graph passing through the points (6, 2) and (10, -1) is:
y = (-3/4)x + 13/2
The correct answer is: Option C: y - 2 = -3/4(x - 6).
Here, we have to find the equation of the line in point-slope form that matches the graph passing through the points (6, 2) and (10, -1), we first need to find the slope (m) of the line using the formula:
[tex]m = (y_2 - y_1) / (x_2 - x_1)[/tex]
where [tex](x_1, y_1) = (6, 2) ; (x_2, y_2) = (10, -1)[/tex].
m = (-1 - 2) / (10 - 6)
m = (-3) / 4
Now that we have the slope (m), we can use the point-slope form of the equation of a line:
[tex]y - y_1 = m(x - x_1)[/tex]
Using the point (6, 2):
y - 2 = (-3/4)(x - 6)
Now, simplify the equation:
y - 2 = (-3/4)x + 9/2
Finally, move -2 to the other side to get the equation in the point-slope form (y = mx + b):
y = (-3/4)x + 9/2 + 2
y = (-3/4)x + 9/2 + 4/2
y = (-3/4)x + 13/2
So, the equation of the line in point-slope form that matches the graph passing through the points (6, 2) and (10, -1) is:
y = (-3/4)x + 13/2
The correct answer is: Option C: y - 2 = -3/4(x - 6).

We need to plot the ordered pair formed by the time and distance on the graph,
The ordered pair are:
(5, 10)
(11, 15)
(18, 20)
Plot the ordered pairs on the graph according to the given values:
The first ordered pair is (5, 10). This means that Timony took 5 units of time to reach a friend's place that is located 10 units of distance away. Mark this point on the graph.The second ordered pair is (11, 15). Timony took 11 units of time to reach a friend's place that is located 15 units of distance away. Mark this point on the graph.The third ordered pair is (18, 20). Timony took 18 units of time to reach a friend's place that is located 20 units of distance away.

Answers
By the Segment Addition Postulate, you can add two adjacent segments to get the total length of the segment.
Given that RS=14
That means that 14 is 1/2 if the total segment length, so we know that segment RT is also = to 14 to make the other half.
We have two lengths that are 14, so we simply add them together to find the total segment’s length.
14+14=28.
The total line segment is 28.

Sketch a possible curve of f(x) given the graphs of f ‘ (x) and f’’ (x) below:
Answers
Step-by-step explanation:
Graph 1 is a parabola and has 2 x points and a turning point
meaning it has a minimum and a maximum point.
conclave points are the highs and lows, once you show this in table then you can interpreted them on a graph see the examples attached.
Graph 1 is opposite to shown interpreted conclave so instead of --c++
we write + + c - - and draw on quadrant 1 instead of quadrant 3
graph 2 is decreasing so instead of -+ c then + + it would show + - c then - - so the curve stays in quadrant 3 and 4. Also where c is we draw a 0 and say whether it is minimum or maximum point.
Both graph 1 and 2 demonstrate minimum points for their f(x) for c.
so in your workings within the table you write min as seen in red within the attachment. They wrote max, but you write min as you are in decreasing conclave fx values that reach min point c then they increase and become parabolas.

Answer:
425 ft
Step-by-step explanation:
So the snorkeling was 30 ft BELOW sea level while the hike was 395 ft ABOVE sea level.
Below is negative so 30 ft below is -30
Above is positive so 395 ft above is 395
the difference between 395 and -30 looks like this:
395- (-30)
So you can simplify to get this equation:
395+30
which is 425
So the difference between the snorkel and hike is 425 ft

Step-by-step explanation:
==>>We would have to multiply the original amount by 1.50^x because the initial amount would be 1, and 50% increase would be .5 so 1.5 and you raise it to the number of years to show the total increase.
Let's test itInitial: 10,000
After 1 year
10,000 + (.5*10000)
10,000 + 5000 = 15,000
--
After 2 years
15,000 + (.5*15000)
15,000 + 7500 = 22,500

Let's try our equation.
[tex]f(x) = 10,000 (1.5)^x[/tex]
