Answer:
Undefined
Step-by-step explanation:
The equation for finding the slope is:
y2 - y1
------------
x2 - x1
--------------------------------------------------------------------------------------------------------
4 - (-8)
----------
-7 - (-7)
-----------------------------------------------------------------------------------------------------------
4 + 8
--------
-7 +7
---------------------------------------------------------------------------------------------------------
12
----
0
---------------------------------------------------------------------------------------------------------
The slope is Undefined, so there is no answer
Using Pythagorean’s theorem, the side length is sqrt(89)
Completion of question:
The Demon Drop at Cedar point in Ohio takes riders to the top of the tower and drops them 60 feet. A function that approximates this ride is h=-16^t2 + 64t + 60 where h is the height in feet and t is the time in seconds. About how many seconds does it take for riders to drop to the ground?
Answer:
4.78 s
Step-by-step explanation:
Given the equation :
h = - 16^t2 + 64t + 60
Using the quadratic formula ; where
a = - 16 ; b = 64 ; c = 60
Dropping to the ground, h = 0
16^t2 + 64t - 60 = 0
-b ± (√b²- 4ac) / 2a
-64 ± (√64²- 4(-16)(60)) / 2(-16)
-64 ± (√7936) / - 32
(-64 ± 89.08) / - 32
(-64 + 89.08) / - 32 = - 0.783 OR
(-64 - 89.08) / - 32 = 4.78
Reject the negative
t = 0.783 seconds
Answer:
The admission cost of each adult is $11.5 and that of each children is $6.5.
Step-by-step explanation:
Let the admission cost for children to the museum is $x.
So, the admission cost for adults to the museum is $(x + 5) {As per given condition}
Now, given that admission to the museum for Barbara and Jeff Johnson and their five children cost fifty-five dollars and fifty cents.
Hence, 2(x + 5) + 5x = 55.5
⇒ 7x = 45.5
⇒ x = $6.5
So, $(x + 5) = $11.5
Therefore, the admission cost of each adult is $11.5 and that of each children is $6.5. (Answer)
Y=1.19x=12.00 the rate of change is 1.19
