- h(t)=-4.9t^2+19.8t+58
- Assuming for same unit length
#1
put t=0 in function
![\\ \rm\hookrightarrow h(0)=58m](https://tex.z-dn.net/?f=%5C%5C%20%5Crm%5Chookrightarrow%20h%280%29%3D58m)
#2
It's already located
![\\ \rm\hookrightarrow T\:at\:H_{max}=4s](https://tex.z-dn.net/?f=%5C%5C%20%5Crm%5Chookrightarrow%20T%5C%3Aat%5C%3AH_%7Bmax%7D%3D4s)
#3
![\\ \rm\hookrightarrow H_{max}=79m](https://tex.z-dn.net/?f=%5C%5C%20%5Crm%5Chookrightarrow%20H_%7Bmax%7D%3D79m)
#4
Count on t axis on graph
#5
Just the initial velocity and height becomes zero
New function
#6
Sam e initial velocity but height becomes zero
New function
60km
Explanation:
Pythagorean theorem
A(2)+B(2)=C(2)
X(2)+32(2)= 68(2)
Plug that into Desmos and you will get 60
Answer:
7/4*3/5
Step-by-step explanation:
x/3/5=7/4
*3/5 *3/5
x=7/4*3/5
The group of five people can be selected in 33649 ways
Step-by-Step Explanation:
When the selection is being made without order then the combinations are used. Permutation is another methods used for selection if the selection has to be distinct. while here, we only have to select a group of 5 people out of 23, we will use combination
Combination is solved by:
![C(n,r)=\frac{n!}{r!(n-r)!}](https://tex.z-dn.net/?f=C%28n%2Cr%29%3D%5Cfrac%7Bn%21%7D%7Br%21%28n-r%29%21%7D)
Here
n = 23
r = 5
Putting the values
![C(23,5)=\frac{23!}{5!(23-5)!}\\=\frac{23!}{5!18!}\\=33649\ ways](https://tex.z-dn.net/?f=C%2823%2C5%29%3D%5Cfrac%7B23%21%7D%7B5%21%2823-5%29%21%7D%5C%5C%3D%5Cfrac%7B23%21%7D%7B5%2118%21%7D%5C%5C%3D33649%5C%20ways)

Each person would get 1/8 of a whole loaf.
If four people are sharing 1/2 of a half of loaf of bread, they each get 1/4. Then you multiply by two to figure out the numbers for the whole loaf, and each person would get 1/8 of the whole loaf.
