A rock is thrown upward with an initial velocity of 16ft/sec from an initial height 5ft. How much time does it take for the rock to hit the ground?
A. -0.25sec
B. 0.5sec
C. 1.25sec
D. 1.5sec
Answer: C
The amount of time it would take for the rock to hit the ground is 1.25 seconds.
Given the following data:
Initial velocity = 16 ft/secHeight = 5 ft.Scientific data:
Acceleration due to gravity (g) = 9.8 [tex]m/s^2[/tex]To determine the amount of time it would take for the rock to hit the ground, we would apply the parabolic function:
How to calculate the time.Mathematically, the parabolic function is given by this formula:
[tex]h(t) = -16t^2 +ut+h_0[/tex]
Where:
U is the initial velocity.a is the acceleration.[tex]h_0[/tex] is the height.t is the time.Substituting the given parameters into the formula, we have;
[tex]0 = -16t^2 +16t+5\\\\16t^2-16t-5=0\\\\(4t+1)(4t-5)=0[/tex]
Taking the positive value of t, we have:
[tex]4t-5-0\\\\4t=5\\\\t=\frac{5}{4}[/tex]
t = 1.25 seconds.

Your family is going on vacation to Disney. It will cost your family $987 to travel there, plus $150 per day for tickets into the park. What is the greatest number of days you can stay at Disney while staying within their $3500 budget?
Answer:
They can stay 16 days.
Step-by-step explanation:
3500 - 987 = 2,513
2,513 divided by 150 = 16.7
*They can't stay 16.7 days, so you have to round down. Rounding up will go out of their budget.*
Checking answer:
16 x 150 = 2,400
2,400 + 987 = $3,387
- I'm sure this isn't how your teacher wants you to solve it but this is just how I solved it, I hope this helps!
Step-by-step explanation:
Equation: 987 + 150x = 3500
x represents the number of days the family is staying at the park.
Solve.
Subtract 987 from both sides:
[tex]150x = 2513[/tex]
Divide each side by 150:
[tex]x= 16.75[/tex]
16.75 is decreased to 16, it's impossible to stay for 16.75 days.
The family can stay in the park for 16 days.
Chad used a number line to show the distance from the library to his house and the distance from the library to Kelli's house. How much farther is Chad's house than Kelli's house from the library? A number line from 0 to 1 is divided into 8 equal parts. Library is at 0, Kelli's House is at four-eighths, and Chad's House is at seven-eighths on the number line.
Chad's house is 3/8 units farther away than Kelly's house.
How to use the number line?By reading the number line, we can see that:
Library = 0Kelli's House = 4/8Chad's House = 7/8.These fractions are the positions of each location. We want to find how much farther is Chad's house than Kelli's house from the library, this is given by:
(Chad's house position - library position) - (Kelli's house position - library position)
Writting the fractions, we get:
(7/8 - 0) - (4/8 - 0) = 3/8
So Chad's house is 3/8 units farther away than Kelly's house.

Little triangle first - hypotenuse is 4, now we used this info help us find the opposite.
Opposite & Hypotenuse - Sin
Sin(45) = O/H
Sin(45) = O/4
x 4 both sides, to get Opposite
Opposite = 4 x Sin(45)
= 2 root 2
= 2.8284.......
Big Triangle next,
Opposite is 2.8284......
Y is the adjacent
Opposite & Adjacent - Tan
Tan (30) = O/A
Tan(30) = 2.8/A
x A
A x Tan(30) = 2.8
÷Tan(30)
A = 2.8 ÷ Tan(30)
A= 2 root 6
A= 4.8989...
So, y is 5 to 1 significant figure
Or
Y = 4.9 to 1d.p

The area of an 17-cm-wide rectangle is 357 cm2. What is its length?
The length is
cm.
Given :-
The area of a rectangle is 357 cm².It's breadth is 17cm .To Find :-
The length of the rectangle.Solution :-
Here the area of the rectangle is 357cm² . As we know that the area of rectangle is ,
→ Area = length * breadth
On substituting the respective values ,
→ 357 cm² = 17cm * length
→ length = 357cm²/17cm
→ length = 21cm
Hence the length of the rectangle is 21cm.

A restaurant owner washed 87 kilograms of vegetables, some spinach and some carrots. The spinach came in 5-kilogram bags and the carrots came in 7-kilogram bags. The owner washed 15 bags of vegetables in all. How many bags of each kind did he wash?
Answer:
9 bags pf spinach, 6 bags of carrots
Step-by-step explanation:
x bags of spinach, y bags of carrots,
x + y = 15 (1)
weight of spinach = 5 * x, weight of carrots = 7 * x
5x + 7y = 87 (2)
From (1) y = 15 - x
Sub it into (2):
5x + 7(15 - x) = 87
5x + 105 - 7x = 87
2x = 105 - 87 = 18
x = 9
y = 15 - x = 15 - 9 = 6
So 9 bags pf spinach, 6 bags of carrots.
work out the area of the shape
Answer:
45cm^2
Step-by-step explanation:
we have two shapes in the diagram a square and a triangle so we find the area of each of them and add them together
finding the area of a square
we have area= s×s
area = 7×5
area = 35cm^2
finding the area of a triangle
1/2 ×b×h
1/2×4×5
area = 10cm^2
so we add together
total area = 35+ 10
area = 45cm^2

Answer: The first four terms are 33/4, 63/8, 15/2, and 57/8.
Step-by-step explanation: To make it easier, turn 8 1/4 into an improper fraction: 33/4. 33/4=66/8. Because the denominator is the same, it’s easier to subtract.
66/8 - 3/8 = 63/8
63/8 - 3/8 = 60/8
60/8 - 3/8 = 57/8
The first 4 terms in the sequence are 66/8, 63/8, 60/8, and 57/8. But we’re not done b/c we need to simplify. That means the first four terms are 33/4, 63/8, 15/2, and 57/8.

Hunter and Christopher were analyzing the graph shown . Both students identified the function to be represented by the, d=13h-75, where d is the amount of money in a checking account and h is the number of hours worked. Hunter explained the equation represented an original amount of $75 that decreased $13 for every hour. Christopher disagreed. He interpreted the equation as a person who was in debt $75 earned $13 every hour.
Using linear function concepts, it is found that Christopher is correct.
What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can be interpreted as the initial value.In this problem, the function is:
[tex]d = 13h - 75[/tex]
Considering the description of the output d as the amount of money in a checking account and of the input h as the number of hours worked, we have that:
For each hour worked, the person earns $13.Considering taxes, the person starts at a debt of $75.Hence, Christopher is correct.
