Answer:

see below

Step-by-step explanation:

f(x)= -(x-2)^2 +4

This is the vertex form of the equation for a parabola

y= a ( x-h)^2 +k  where (x,k) is the vertex of the parabola

a = -1   h= 2   k = 4

The vertex is ( 2,4)

Answer:

Completed square form

a = -1

h = 2

k = 4

Vertex: (2,4)

Step-by-step explanation:

f(x)= -(x-2)^2 +4 is in the complete square form

f(x) = a(x - h)² + k

a = -1

h = 2

k = 4

Vertex: (2,4)

Solve the equation using the Quadratic Formula. x2 - 8x + 15 = 0 Select the correct choice below and, if necessary, fill in the
Ahat [919]

Answer:

x = (5,3)

Step-by-step explanation:

the quadratic formula is x =( -b±√(b^2-4ac))/2a

to solve for x, a=1, b=-8,c=15

x =( -(-8)±√((-8)^2-4*1*15))/2(1)

x=8 ± √(64-60))/2(1)

x=(8 ± √(4)) / 2

x=(8 ± 2) / 2

solve with '+'

x=(8 + 2) / 2 = 10/5 = 5

solve with '-'

x=(8 - 2) / 2 = 6/2 = 3

x = (5,3)

A grocer sold 45% of his stock of sugar and the quantity that he sold was 96 kg less than the quantity left how much sugar did h
zmey [24]

Answer:

He sold 960 kg

Step-by-step explanation:

Let the initial stock measure be x kg

So if he sold 45% ; what he sold was;

45/100 * x = 0.45x

So the quantity left would be;

x - 0.45x = 0.55x

So what was left is 96kg more than what was sold

Mathematically, we have this as;

0.55x - 0.45 x = 96

0.1x = 96

x = 96/0.1

x = 960 kg
