Jon is hitting baseballs. When he tosses the ball into the air, his hand is 5 feet above the ground. He hits the ball when is falls back to a height of 4 feet. The height of the ball is given by h(t)=5+25t-16t^2, where t is the time in seconds.
a) How much time will pass before Jon hits the ball? (round to the nearest tenth of a second)
b) What is the time in which the maximum height the ball attains? ( to the nearest hundredth of a second)
Answer: A= 1.60 sec
And I am not sure if B is correct, but I got 14.77 ft.
Step-by-step explanation:
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Jon who is hitting baseballs. When he tosses the ball into the air, his hand is 5 feet above the ground. He hits the ball when is falls back to a height of 4 feet. The height of the ball is given by -
h(t) = 5 + 25t - 16t²
where [t] is the time in seconds.
[A] -
At h = 4ft, we can write -
4 = 5 + 25t - 16t²
- 16t² + 25t + 1 = 0
On solving, we get -
t = 1.602 seconds
[B] -
We have -
h(t) = 5 + 25t - 16t²
For maximum height -
dh/dt = 0
d/dt(5 + 25t - 16t²) = 0
0 + 25 - 32t = 0
32t = 25
t = 25/32
t = 0.79 seconds
Therefore -
t = 1.602 seconds will pass before Jon hits the ball.At t = 0.79 seconds the ball attains maximum height.To solve more questions on Equation Modelling, visit the link below -

A cyclist rides a distance of 36 km at an average speed of 16 km/h.
Calculate the time taken to complete this ride. Give your answer in hours and minutes.
Please Help!
Answer:
2.25 hours, or 2 hours and 15 minutes.
Step-by-step explanation:
All we do is 36/16 which is 2.25. 0.25 or 1/4 of an hour is 15 minutes. So, your answer is 2 hours and 15 minutes.
It takes 2 hour and 12 minutes for the cyclist to complete the ride of 36km distance.
What is unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Total distance covered by cyclist= 36km
Average speed of the cyclist = 16km/hr
Therefore, using unitary method:
16 km distance takes time = 1hr
Therefore, 1 km distance takes time =(1/16)hr
Therefore, 36 km distance takes time = (1/16)×36 hr
=(1/4)×9 hr
=9/4 hr
=2.25 hr
=(2+0.25)hr
=2hr+0.25hr
=2hr+0.25×60minutes
=2hr and 15 minutes.
Hence, it takes 2hr and 15 minutes for the cyclist to complete 36 km rides.

Every autumn, the North American Monarch
butterfly migrates up to 3,000 miles to California and Mexico where it hibernates
until early spring. The butterfly travels on average 50 miles per day.
Part A
The equation is d = 50t
This is because the slope of 50 represents how many miles per day the butterflies cover (on average). The y intercept is 0 to indicate that 0 miles have been traveled initially.
You can think of this as the equation y = 50x
If t = 1, then d = 50t = 50*1 = 50 miles have been covered
If t = 2, then d = 50t = 50*2 = 100 miles have been covered
And so on.
==========================================================
Part B
You'll have these values in the bottom row (in the order presented): 50, 100, 150, 200, 250
You can plug in the values t = 1, t = 2, t = 3, t = 4 and t = 5 into d = 50t to find those answers in bold.
Or you could add on 50 each time to generate each new value. We start at 50 since t = 1 corresponds to d = 50.
==========================================================
Part C
You can keep the pattern of 50,100,150, ... going until you reach 2500. Then note the t value that pairs with d = 2500
In my opinion, that's the slower method.
The quicker method is to plug d = 2500 into the equation for part A, and then solve for t.
d = 50t
2500 = 50t
50t = 2500
50t/50 = 2500/50 ....... divide both sides by 50
t = 50
It will take 50 days for the average distance traveled to be 2500 miles.

The bronx zoo opened at 9.00 am. In the first hour 280 people purchased admission tickets. In the second hour 25 percent more people purchased admission people than the first hour . Each ticket cost 16.25. What was the total amount of money paid for all the tickets purchased in the first two hours
Answer:
Total amount paid for tickets in the two hours = $10,237.50
Step-by-step explanation:
Step 1
Ist Hour, 280 tickets were sold at the cost of $16.25
Amount of money made in the first hour= Number of people who purchased ticket x price of a ticket
=280 x 16.25 =$4,550
2nd Hour, 25 % more people purchased ,
which means the total number of people who purchased tickets =
1.25 x 280= 350
Amount of money made in second hour = Number of people who purchased ticket x price of a ticket 350 x 16.25 =$5,687.5
Step 2
Total amount paid for tickets in the two hours = Amount of money made in the first hour +Amount of money made in second hour
=$4,550+ $5,687.5
=$10,237.50
A triangle has a base of 10 centimeters and a height of 12 centimeters. A rectangle has a base of 10 centimeters and a height of 12 centimeters.
What are the areas of the figures?
The area of the triangle is
___ cm2.
The area of the rectangle is
___ cm2.
The area of the triangle is
60 cm2.
The area of the rectangle is
240 cm2.
In a two-dimensional plane, an area of triangle is equal to the sum of the areas of its three sides.
To calculate a rectangle's area, count the number of square units that fit within the rectangle's perimeter.
Area of triangle = h x b / 2
Given
h = 12
b =10
hence
A= h x b / 2

Answer:
5^2+h^2=12^2, the answer would be ~10.97 ft.
Step-by-step explanation:
I would use the Pythagorean theorem to solve this problem. Put in the things that you know, so in this image we are given one of the legs and the hypotenuse of the triangle.
Pythagorean theorem is :
a^2+b^2=c^2 with a and b being the legs and c being the hypotenuse.
Once you plug in the hypotenuse and one of the legs, solve for the other leg by subtracting a^2 (5^2) from 12^2 (c^2), which will give you 119, and then take the square root of 119 and you will get your answer.

Answer:
30cm
Step-by-step explanation:
Given data
When are square is cut diagonally into two parts
The resulting shape is a triangle
hence the area of the square = 50+50 = 100cm^2
The length of each side of the square = √100= 10cm
likewise the diagonal of the square = 10cm
Hence the perimeter of the resulting triangle= 10+10+10= 30cm

What single transformation was applied to triangle A to get triangle B?
Answer:
should be reflection
Step-by-step explanation:
bc a translation would just move it and rotation and dilation wouldn't work either
The single transformation was applied to triangle A to get triangle B is a reflection, in which A is reflected around the y-axis.
What is reflection?Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point.
Given:
The triangles A and B are shown in the given figure,
Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original,
Rotation is the process of going around a center.
A shape is translated when it is moved up, down, left, or right without turning. They are congruent if the translated shapes (or the image) seem to be the same size as the original shapes.
Thus, triangle A is reflected as B.
