Darryl Dixon shoots an arrow at a zombie. The path of the arrow can be modeled with the equation y=-x^2 42x-80, where x is time in seconds and y is the height in feet. How long does it take for the arrow to reach its maximum?
We need to find time taken to reach arrow to its maximum.
The path of the arrow can be modeled with the equation [tex]y=-x^2+ 42x-80[/tex] .
Differentiating the given equation w.r.t x and equate it to zero.
[tex]\dfrac{dy}{dx}=-2x + 42 \\\\42 - 2x = 0\\\\x = 21\ seconds[/tex]
Putting value of x = 21 sec in given equation, we get :
[tex]y=-x^2+ 42x-80\\\\y = -(21)^2 + (42\times 21) - 80\\\\y = 361 \ feet[/tex]
Therefore, time taken to reach maximum height is 21 seconds.

Answer:
[tex]d_{AB}\ne d_{JK}[/tex]
[tex]d_{AB}\ne \:d_{GH}[/tex]
[tex]d_{GH}\ne \:d_{JK}[/tex]
Therefore,
Option (A) is false
Option (B) is false
Option (C) is false
Step-by-step explanation:
Considering the graph
Given the vertices of the segment AB
A(-4, 4)B(2, 5)Finding the length of AB using the formula
[tex]d_{AB}\:=\:\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
[tex]=\sqrt{\left(2-\left(-4\right)\right)^2+\left(5-4\right)^2}[/tex]
[tex]=\sqrt{\left(2+4\right)^2+\left(5-4\right)^2}[/tex]
[tex]=\sqrt{6^2+1}[/tex]
[tex]=\sqrt{36+1}[/tex]
[tex]=\sqrt{37}[/tex]
[tex]d_{AB}\:=\sqrt{37}[/tex]
[tex]d_{AB}=6.08[/tex] units
Given the vertices of the segment JK
J(2, 2)K(7, 2)From the graph, it is clear that the length of JK = 5 units
so
[tex]d_{JK}=5[/tex] units
Given the vertices of the segment GH
G(-5, -2)H(-2, -2)Finding the length of GH using the formula
[tex]d_{GH}\:=\:\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
[tex]=\sqrt{\left(-2-\left(-5\right)\right)^2+\left(-2-\left(-2\right)\right)^2}[/tex]
[tex]=\sqrt{\left(5-2\right)^2+\left(2-2\right)^2}[/tex]
[tex]=\sqrt{3^2+0}[/tex]
[tex]=\sqrt{3^2}[/tex]
[tex]\mathrm{Apply\:radical\:rule\:}\sqrt[n]{a^n}=a,\:\quad \mathrm{\:assuming\:}a\ge 0[/tex]
[tex]d_{GH}\:=\:3[/tex] units
Thus, from the calculations, it is clear that:
[tex]d_{AB}=6.08[/tex]
[tex]d_{JK}=5[/tex]
[tex]d_{GH}\:=\:3[/tex]
Thus,
[tex]d_{AB}\ne d_{JK}[/tex]
[tex]d_{AB}\ne \:d_{GH}[/tex]
[tex]d_{GH}\ne \:d_{JK}[/tex]
Therefore,
Option (A) is false
Option (B) is false
Option (C) is false

If 14 gallon of paint covers 13 of a wall in Luna's bedroom, how much paint does she need to cover 1 wall?
Answer:
182
Step-by-step explanation:
1/13=14 gal
14 times 13 = 182 gal.
Unless you wrote it diff, then it would be 14/13 = 1.08 gal (I don't think this one is correct though)

If a ladder is to be placed 3 feet from the side of a house. If top of the ladder rests exactly on the edge of the house when it is placed at an angle of 72 degrees from the ground, how long is the ladder to the nearest foot?
Answer:
7 feet long
Step-by-step explanation:
This set up will give a right angle triangle where;
Length of the ladder is the hypotenuse = x
The distance of the ladder to the house is the adjacent = 3 feet
Angle of elevation theta = 72 degrees
Using the CAH in trigonometry identity;
cos theta = adjacent/hypotenuse
cos 72 = 3/hyp
hyp = 3/cos72
hyp = 3/0.4258
hyp = 7.05 feet
Hence the ladder is approximately 7 feet long

The Dubois family has $5000 set aside for an upcoming vacation in the family plans to spend 1/4 of this amount on gasoline for the drive and motel rooms along the way and 1/2 of the remainder on meals how much does the Dubois family spend on meal
Answer:
$1875
Step-by-step explanation:
Money available with Dubois family = $5000
Money to be spent on gasoline and motel room = [tex]\frac{1}{4}[/tex] of the total amount
Therefore,
Money to be spent on gasoline and motel room = [tex]\frac{1}{4} \times 5000 = \$1250[/tex]
Remaining amount of money = Total amount - Money spent on gasoline and motel room
Remaining amount of money = $5000 - $1250 = $3750
As per question statement:
Half of the remaining money is to be spent on meals.
i.e. Money to be spent on meals = [tex]\frac{1}{2}\times \$3750 = \bold{\$1875}[/tex]
Therefore, the answer is:
$1875
Bill averages 10 points a game and has 110 points for the season. Aaron averages 12 points a game and has 96 points for the season. Solve an equation to find how many games it will take until they tie in points scored if they continue at the same rate.
Answer:
ok yes
Step-by-step explanation:
The number of games it will take until they tie in points scored if they continue at the same rate is;
7 games.
We are told that Bill averages 10 points a game and has 110 points for the season.
Thus, number of games a season it will take bill to reach 110 points is; 110/10 = 11 games
Aaron averages 12 points per game and has 96 points for the season. Thus, number of games a season it will take bill to reach 96 points is;
96/12 = 8 games.
Now, let the additional number of games to be played for them to have the same points be x. Thus;
110 + 10x = 96 + 12x
12x - 10x = 110 - 96
2x = 14
x = 14/2
x = 7
In conclusion, the additional number of games it will take for Bill and Aaron to have the same number of points is 7 games.
