Answer:
Robbie Glider
<u></u>
Step-by-step explanation:
Given
<u>Melissa Glider</u>
<u>Robbie Glider</u>
See attachment for function
Required
Which reaches the greater maximum within the first 6 seconds
<u>Melissa Glider</u>
First, we calculate the maximum of Melissa's glider
Differentiate:
Equate to 0 to find the maximum
Divide through by 0.4
Solve for s using quadratic formula:
Where
So:
Split:
This implies that Melissa's glider reaches the maximum at 5.4 seconds or 1.9 seconds.
<em>Both time are less than 6 seconds</em>
Substitute 5.4 and 1.9 for s in to get the maximum
The maximum is 10.02ft for Melissa's glider
<u>Robbie Glider</u>
From the attached graph, within an interval less than 6 seconds, the maximum altitude is at 3 seconds
<em>Compare both maximum altitudes, 22ft > 10.02ft. This implies that Robbie reached a greater altitude</em>
Answer:
a = (2A)/h - b
Step-by-step explanation:
A=1/2h(a+b) for a
Multiply both sides by 2:
2A=h(a+b)
Divide both sides by h:
(2A)/h = a + b
Subtract b from both sides:
(2A)/h - b = a
Switch sides:
a = (2A)/h - b

ANSWER: y= 3x - 6
STEP-BY-STEP EXPLANATION:
(1,-3) and (3,3)
X1=1 X2=3
Y1= - 3 Y2=3
1) Find the slope of the line.
To find the slope of the line passing through these two points we need to use the slope formula:
m =
m= m= = 3
2)Use the slope to find the y-intercept.
Now that we know the slope of the line is 3 we can plug the slope into the equation and we get:
y= 3x+b
Next choose one of the two point to plug in for the values of x and y. It does not matter which one of the two points you choose because you should get the same answer in either case. I generally just choose the first point listed so I don’t have to worry about which one I should choose.
y= 3x+b point (1,-3)
-3= 3(1) + b
-3-3=b
-6=b
3)Write the answer.
Using the slope of 3 and the y-intercept of -6 the answer is:
y = 3x - 6
Answer:
If your asking for someone to solve with the work then i believe its -6x
Step-by-step explanation:
I might be wrong so get a second opinion but i think its:
3x(11x-13)
-distribute the 3x to 11x and 13. 3x times 11x is 33x and 3x times 13 is 39x.
Then you get 33x-39x
-subtract. 33x-39x and you get an answer of -6x.
