Answer:
a=4, b=144
Step-by-step explanation:
Let's take two random points of X and y and simplify the equation containing a and b; let's go,
Points (4,-5); (6,0)
For (4,-5)
-5= a -b/ (4 x4)
-5= a- b/16; -80= 16a - b[ by multiplying through by 16]
For (6,0);
0= a -b/ ( 6x6) ; 0=a- b/36
Multiplying through by 6, we have:
0= 36a-b; 36a=b;
So the modified equation of a and b are;
b=36a
b=16a+ 80[ modifying the derived expression moving b to the left]
So if we equate both expressions,
We have:
36a=16a+80;
36a-16a=80, 20a= 80; a= 80/20= 4;
a=4;
Substituting the value of a into any expression for b; we have
b= 36a= 36x4 =144
Hence a=4, b= 144
Y=a-b/x².
Using first column: x=1, y=140
140=a-b
Using last colimn: x=6, y=0
0=a-b/36, b=36a
140=a-b=a-36a=-35a
a=-140/35=-4
b=36a=36×(-4)=-144
Answer: a=-4, b=-144

Step-by-step explanation:
which two numbers multiply to give you 100 and add to give you 10
Answer:
The velocity of the object is 76.73 ft/sec
Step-by-step explanation:
* Lets explain how to solve the problem
- The formula y = √(64h) gives the velocity y in feet per second of an
object that has fallen h feet
- To find the velocity of an object that has fallen 92 feet substitute h
by 92 in the formula
∵ y = √(64h)
∵ h = 92 feet
∴ y = √64(92) = √5888 ≅ 76.73 feet/seconds
* The velocity of the object is 76.73 ft/sec
The difference between 400 and 273 is 127
The given numbers are,
400 and 273
The difference between 400 and 273 is calculated by subtracting the smaller number from the larger number. So,
400 - 273 = 127.
Now take a creative approach to solve it,
Imagine you have a basket of 400 apples, and a friend takes away 273 apples. How many apples do you have left?
Simply subtract:
400 - 273 = 127.
Or simply
4 0 0
- 2 7 3
__________
1 2 7
___________
So, the difference between 400 and 273 is 127 apples.
