Step-by-step explanation:
nobody knows!!
The answer is 20. Multiply 5/6 by 24 to get 20.
The vertex of the parabola is (0,4), because you can use -b/2a to find the x coordinate a of the vertex. There is no b so b=0 and 0/anything is 0. Then you can plug 0 into the equation to find the y coordinate of the vertex. When you plug in 0 you get 4, so the vertex is (0,4)
Answer:
Step-by-step explanation:
Given triangle is a right angle triangle
To find out x we use Pythagorean theorem
where c is the hypotenuse
c=square root (20),
Plug in the values in the formula
Subtract 20 on both sides
Divide whole equation by 2
0=x^2-2x-8
factor the right hand side
Set each factor =0 and solve for x
so
so
The length x cannot be negative, so
4 1/2 + 3 1/4 + 2 1/4 = 10 pounds of apples.
10 pounds is approximately 4.5 kilograms.
