Given :
The height of a building is 1417 ft.
To Find :
How long would it take an object to fall to the ground from the top.
( Use the formula s = 16t² where s is the distance, in feet traveled by an object falling freely from rest in seconds. )
Solution :
Putting value of height in given equation, we get :
[tex]16t^2 = 1417\\\\t^2 = \dfrac{1417}{16}\\\\t^2 = 88.5625\\\\t = \sqrt{88.5625}\\\\t = 9.41 \ seconds[/tex]
Therefore, time taken by object to reach the ground is 9.41 seconds.

Answer:
y = -2x + 17
Step-by-step explanation:
The line is parallel to 4x + 2y = 10, and parallel lines have the same slope. Let's convert this line into slope intercept form:
2y = 10 - 4x,
y = -2x + 5
So the slope of this line and our line [the line which we want to determine in slope intercept form] is -2
Given the point (7, 3) and slope -2 we can solve for the y-intercept;
y = mx + b,
3 = -2(7) + b,
-14 + b = 3,
b = 17
Your solution is y = -2x + 17 (First option)

A group of biologists found a total of 28 loggerhead turtle nests along a beach during a certain season. This was 40% of the total number of turtle nests the group found during that season. What was the total number of turtle nests the group found during that season?
70
85
110
143
Answer:
A
Step-by-step explanation:
Let T represent the total number of turtle nests found during the season.
The 28 turtle nests was 40% of 0.4 of the total. Therefore:
[tex]28=0.4T[/tex]
So, to find T, divide both sides by 0.4:
[tex]T=70[/tex]
So, the total number of turtle nests the group found during tthe season was 70.
Hence, our answer is A.

From his house, Shane could drive due north to get to his parents' house or he could drive due east to get to his grandparents' house. It is 8 miles from Shane's house to his parents' house and a straight-line distance of 17 miles from his parents' house to his grandparents' house. How far is Shane from his grandparents' house?
Answer:
15 miles
Step-by-step explanation:
It is given that,
Shane could drive due north to get to his parents' house or he could drive due east to get to his grandparents' house.
It is 8 miles from Shane's house to his parents' house and a straight-line distance of 17 miles from his parents' house to his grandparents' house.
It can be calculated by considering a right angled triangle. Using pythagoras theorem, we can find the distance between Shane from his grandparents' house. Let it is d.
[tex]d^2=\sqrt{17^2-8^2} \\\\=15\ \text{miles}[/tex]
Hence, Shane is 15 miles from his grandparents' house.

What is 72 Divided by 2= ??
Answer:
72 / 2 = 36
Step-by-step explanation:
Look at 7 first and figure out how many times 2 will go into 7. 2 will only go into 7 three times. (2 x 3= 6) So put 3 at the top of your division problem and subtract 6 from 7. You should get 1. Then, bring down your 2 to make that one a 12. How many times will 2 go into 12? 6 times. 6 x 2 equals 12 so put 6 at the top of your division problem next to that 3. Subtract your 12 from 12 to get 0. Your final answer would be 36.
Hope this helped!

(1) The first velocity of the car with two washers at the 0.25 meter mark is 0.125 m/s.
(2) The second velocity of the car with two washers at the 0.5 meter mark is 0.25 m/s.
What is velocity?Velocity is the rate of change of displacement with time. The velocity of the cars depends on displacement and time of motion.
First velocity of the car at the 0.25 meter markThe first velocity is calculated as follows;
v1 = 0.25 m / t1
let t₁ = 2 s
v₁ = 0.25/2
v₁ = 0.125 m/s
Second velocity of the car at the 0.5 meter markv2 = 0.25 m / (t2 – t1)
let t₂ = 3 s
v₂ = 0.25(3 - 2)
v₂ = 0.25 m/s

Bob's monthly net income is $3,000. Bob pays $950 for rent, $250 for all
utilities, and $1,850 in other fixed and variable expenses. What is Bob's
cash flow?
A.Negative cash flow, $50
B.Negative cash flow, $3,050
C.ositive cash flow, $3,050
D.Positive cash flow, $50
Answer:
A: Negative cash flow, $50
Step-by-step explanation:
Bob makes $3000 a month.
Every month he has to pay $950:
3000 - 950 = 2050
Pay an additional $250:
2050 - 250 = 1800
And another additional $1850:
1800 - 1850 = -50
Therefore, he has a negative cash flow of $50 a month.

Answer:
An equation for the parabola would be y²=-19x.
Since we have x=4.75 for the directrix, this tells us that the parabola's axis of symmetry runs parallel to the x-axis. This means we will use the standard form
(y-k)²=4p(x-h), where (h, k) is the vertex, (h+p, k) is the focus and x=h-p is the directrix.
Beginning with the directrix:
x=h-p=4.75
h-p=4.75
Since the vertex is at (0, 0), this means h=0 and k=0:
0-p=4.75
-p=4.75
p=-4.75
Substituting this into the standard form as well as our values for h and k we have:
(y-0)²=4(-4.75)(x-0)
y²=-19x
Step-by-step explanation:
GOOD LUCK
