A drone carrying fireworks is launched from a platform above a lake and follows a parabolic path. It will set off the fireworks at its highest point. The drone’s height above the surface of the lake is given by the function h(t) = -16t2 + 64t + 80, where h represents height in feet and t represents time in minutes. a. How high is the platform? b. From what height will the fireworks be released? c. When does the drone land?
Answers
Answer: Answer is in the steps
Step-by-step explanation:
using the function h(t) = -16t^2 + 64t + 80 and H is height in feet t is the time in minutes we can evaluate how high the platform is by solving for the y intercept.
h(t) = -16t^2 + 64t + 80 the y intercept is when h(t) is h(0) so when it is h of zero put zero into the function and solve the function
A) -16(o)^2 + 64(0) + 80
0 -0 + 80
h(0) = 80
Which means the platform is 80 feet high.
B) In the reading it says that it will set the firework at its highest point and in other words its highest point is its vertex. So solve for the vertex .
h(t) = -16t^2 +64t + 80 To solve for the vertex, use the formula x= -b/2a to find the x coordinate of the vertex.
so the value of b is 64 and a is -16 .
x = -64 / -32
x = 2
So the x coordinate of the vertex is 2 so input it and solve for the y coordinate of the vertex.
h(t) = y = -16(2)^2 + 64t+80
y= -16(4) + 64(2)+ 80
y= -64 + 128 + 80
y = 144
So the y coordinate is 144. which means the vertex is (2,144) and also means that the fireworks will be released at a 144 feet.
C) The drone will land on the ground when they is not height which means when y is equal to zero or h(t) is zero.
-16t^2 +64t + 80 = 0 so solve for t using the quadratic formula.
The quadratic formula says that x= -b ± [tex]\sqrt{b^2 -4ac} /2a[/tex]
a = -16 b= 64 and c= 80
x = -64 + [tex]\sqrt{9216}/ -32[/tex]
x= -64 ± 96 /-32
x= -1 or x = 5
Which means the drone land on the ground in 5 minutes. It can't be -1 because a negative number can't represent time.

Shelley compared the number of oak trees to the number of maple trees as part of a study about hardwood trees in a woodlot. She counted 9 maple trees to every 5 oak trees. Later in the year there was a bug problem, and many trees died. New trees were planted to make sure there were the same number of trees as before the bug problem. The new ratio of the number of maple trees to the number of oak trees is 3:11. After planting new trees, there were 132 oak trees. How many more maple trees were in the woodlot before the bug problem than after the bug problem?
Answers
Answer:
72
Step-by-step explanation:
Initial ratio of maple trees to oak trees
9:5New ratio of maple trees to oak trees
3:11Number of oak trees = 132
Number of maple trees
132*3/11 = 36Total number of trees
132+36 = 168Initial number of maple trees
168*9/14 = 108The difference in the number of maple trees:
108 - 36 = 72Answer:
72 more trees before the bug problem
Step-by-step explanation:
The ratio was 9:5 before the bug problem and 3:11 after.
After the bug problem there were 132 oak trees,
m : 132 = 3 : 11
Then we know
m/132 = 3/11
Multiplying both sides by 132 cancels on the left
132 × (m/132) = (3/11) × 132
m = (3/11) × 132
Then solving for m
m = 132 × (3/11)
m = 36 This gives us the number of trees after the bug problem.
This would give us 168 trees in total, 132 oak, and 36 maple.
Since there is the same number of trees as before we calculate the number of maple and oak previously.
If Shelley counted 9 maple for every 5 oak we know that 9 out of 14 trees are maple and 5 out of 14 trees are oak.
9/14 = .6428 which is the percentage of maple trees before the bug problem.
We multiply .6428 x 168 (the total number of trees) and we get 108.
if there are 108 maple trees then 168-108 = 60 oak trees.
Further proof:
9:5 or 9/5 = 1.8 108/60 = 1.8
108 maple trees and 60 oak before the bug problem.
So 108 (maple before bug problem) and 36 maple trees after:
108 - 36 = 72 more trees before the bug problem

Is this an appropriate sampling method? No. This convenience sample is very biased and is highly unlikely to be representative of national public opinion. Yes. This convenience sample is appropriate for the limited resources of a news website and is likely to be representative of the population. Yes. This simple random sample is ideal and will be representative of the population. No. This systematic sample is very biased and is highly unlikely to be representative of national public opinion.

Answer:
No. This convenience sample is very biased and is highly unlikely to be representative of national public opinion.
Step-by-step explanation:
The sampling as per its nature should be classed as convenience sample because of its definition: this method covers part of the population with easy to reach or close to hand.
This involves only those who will access the website and this can not be considered as representative of national public opinion.

A dog spots a cat 50 feet away and starts to chase it. At the same moment, the cat starts to run away from the dog. The dog is running 12 feet per second and the cat is running 10 feet per second. Let t represent the time elapsed (in seconds) since the chase began. Let d represent the distance between the cat and the dog (in feet) Write a formula to define the distance between them (d) in terms of the time elapsed (t).
Answers
Answer:
D(t) = 50 -2t
At 25 seconds, the dog caught up with the cat
Step-by-step explanation:
At initial time t0
Distance = 50 ft
The dog is running 12 feet per second and the cat is running 10 feet per second.
So for each each time in seconds
Dog covers 12 feet while cat extends by 10 ft .
The distance between them at any given time
D(t)= 50 +10t -12t
D(t) = 50 -2t
The time it will take the dig to get to the cat is what D= 0
D(t) = 50 -2t
0= 50- 2t
2t= 50
t= 25
So at 25 seconds, the dog caught up with the cat

Answers

Step-by-step explanation:
Given
Point: A(2,6)
Translation: 1 left and 3 up
Rotation: 180 degrees
Required
Image of Point A
Taking the exercise one after the other
Represent the function as: (x,y)
Such that
[tex]A(x,y) = A(2,6)[/tex]
1 unit left translation means the function becomes (x - 1, y)
2 unit up translation means the function becomes (x - 1, y + 2)
Applying the above transformation
[tex]A(2,6) -> A(2-1,6+2)[/tex]
[tex]A(2,6) -> A(1,8)[/tex]
At this stage, the coordinate becomes
[tex]A(1,8)[/tex]
When a function (x,y) is rotated by 180, the new function becomes (-x,-y)
So;
The further transformation of A is
[tex]A(1,8) -> A(-1,-8)[/tex]
Hence, the new image of A is
[tex]A(-1,-8)[/tex]

In a race, there are 20 runners. Trophies for the race are awarded to the runners
finishing in first through fourth place.
In how many ways can first through fourth place by determined?
Answers
Answer:
116,280 ways
Step-by-step explanation:
Because your finish place is mutually exclusive (if you come in first you cant come in second, if you come in second you cant come in third, etc) you have to decrease the amount of runners for each place.
20 runners can get first
19 for second
18 for third
17 for fourth.
To find out the total amount of possibilities you multiply each amount. 20 x 19 x 18 x 17 = 116,280.

A student currently is averaging 65.0% of the points in lecture (worth 60% of total grade) and has a 75.0% in lab (worth 40% of total grade). What is her total course % at this time?
Answers
Answer:
69
Step-by-step explanation:
If she is averaging 65% of the worth of lectures.
the lectures she had was supposedly rated out of 60. Therefore, the 65% will be 65% of 60(total grade)
0.65 * 60 = 39
On the second part, if we apply the same method, we have
0.75 * 40 = 30
All we have to do on add both together
39 + 30 = 69.
therefore, get total grade in the course is 69
Total grade in the course is 69%
Percentage :Since, the averaging 65% of the points in lecture is worth to 60% of total grade.
It means that, the 65% will be equivalent to,
[tex]=\frac{60*65}{100}=3900/100=39[/tex] percent of total grade.
And 75% in lab is worth 40% of total grade.
[tex]=\frac{75*40}{100}=30[/tex] percent of total grade.
We have to add both together
[tex]39 + 30 = 69.[/tex]
Thus, total grade in the course is 69%
