Step-by-step explanation:
in that setup they will both explode after traveling the same distance.
A is just going faster and has to launch therefore a little bit later.
so, we need to make an equation based on distance traveled and find in that process the number of seconds needed to travel that distance.
speed is distance/time, so we need to multiply speed by time to get distance.
x = seconds for B
x - 0.25 = seconds for A
A is launched after B but explodes at the same time.
so, A's trip is of shorter time than B's trip.
(x - 0.25)×360 = x×320
360x - 90 = 320x
40x - 90 = 0
40x = 90
4x = 9
x = 9/4 = 2.25 seconds
both fireworks will explode 2.25 seconds after B launches (and 2.25 - 0.25 = 2 seconds after A launches).
the explosion will be at
320×2.25 = 360×2 = 720 feet height.
Graph DFG with vertices D(2,8), F(1,2) and G(4,6) and image after the glide reflection with a translation along <3,3> and a reflection in the y=x
The vertices of the figure after geometric translations are (11, 5), (5, 4), and (9, 7).
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
It is given that:
The vertices are D(2,8), F(1,2) and G(4,6).
Points become after reflection:
D'(8, 2), F'(2, 1), G'(6, 4)
After applying translation:
D''(8+3, 2+3) = (11, 5)
F''(2+3, 1+3) = (5, 4)
G''(6+3, 4+3) = (9, 7)
Thus, the vertices of the figure after geometric translations are (11, 5), (5, 4), and (9, 7).

Point C is the midpoint of AB and point B is between points A and D . If AD=17 and BD=9 , what is CD ?
CD=
Answer: 13 units
Step-by-step explanation:Given that Point C is the midpoint of AB and point B is between points A and D. If AD = 17 and BD = 9
According to definition midpoint, AC = CB
According to definition of segment addition postulate, AD = AB + BD
AB = AD - BD
AB = 17 - 9
AB = 8
Again, AB = AC + CB
Therefore, CB = AB/2
CB = 8/2 = 4
Now, CD = CB + BD = 4 + 9
CD = 13 units
Hence, length of CD = 13 units

Aquarium a contains 4. 6 gallons of water. Louise will begin filling aquarium a at a rate of 1. 2 gallons per minute. Aquarium b contains 54. 6 gallons of water. Isaac will begin draining aquarium b at a rate of 0. 8 gallon per minute.

A(y) = 4.6 + 1.2y
B(x) = 54.6 - 0.8y
Same amount of water:
A(x) = B(x)
4.6 + 1.2y = 54.6 - 0.8y
1.2y + 0.8 y = 54.6 - 4.6

a tunnel is constructed with a semielliptical arch. the width of the tunnel is 60 feet, and the maximum height at the center of the tunnel is 25 feet. what is the height of the tunnel 5 feet from the edge? round your answer to the hundredths place.
As a result, the tunnel is 13.83 feet high, 5 feet from the edge.
An ellipse is an oval curve on a plane that contains two fixed points called foci. The sum of the distances between the two foci from each point on the ellipse is constant at all points.
Since the tunnel has an arch that is semi-elliptical, we can put the ellipse's center at the center of its 60-foot width.
What is an ellipse?
An ellipse is a two-dimensional shape that is defined by its axes in geometry. When a plane intersects a cone at an angle to its base, it creates an ellipse. It focuses on two things. For each point in the curve, the sum of the two distances to the focal point remains constant.
What are an ellipse and an example?
An ellipse is the locus of points whose sum of their distances from its two foci is constant and has an eccentricity of less than one. The two-dimensional egg shape and the running tracking in a sports stadium are simple examples of the ellipse in our everyday lives.

Given;
Let x be the overall number of cartons produced in a single day. due to the factory's daily production limit of 500 cartons.
Let P(x) denote the revenue generated by the sale of x cartons. Since a carton costs $25, the following follows;
P(x) = 25x
P(0) = 25(0) = 0 for x = 0
P(500) = 25(500) = 12500 when x = 500
The following are possible values for P(x);

f(x) = -5x − 9
g(x) = 8x − 4
we have to determine which equation defines function h
f(x) = -5x − 9
g(x) = 8x – 4
(f x g) (x) = (-5x –9)(8x – 4)
(f x g) (x) = -40x2 + 20x – 72x + 36

find two positive numbers such that the sum of the first and twice the second is 120, and their product is a maximum. as your answer, please input the maximal value of the product.
The sum of two positive numbers is 120. The product of those numbers will be maximum if both numbers are equal to 60 and the maximum value is 3600.
Suppose we have a function f(x). At the extreme point (maximum/minimum), it holds:
f ' (x) = 0
In the given problem, let the two numbers be a and b. Then,
a + b = 120 or
a = 120 - b (equation 1)
f(b) = a x b = (120 - b) x b
f(b) = -b² + 120b
At the maximum point, the derivative with respect to b is zero,
f ' (b) = 0
-2b + 120 = 0
b = 120 / 2 = 60
Substitute b = 60 to equation 1,
a = 120 - 60 = 60
Hence, the two numbers that give maximal value of the product is 60 and 60. The product is 60 x 60 = 3600.
We can conclude that the maximum value of the product of those two numbers is 3600.
