Find the vertex, zero(s), and y-intercept of the graph of y = –x2 + 4x + 32.
xxMikexx [17]

Answer:

The correct option is A.

Step-by-step explanation:

The given equation is

y=-x^2+4x+32

Put x=0, in the given equation.

y=-(0)^2+4(0)+32=32

The y-intercept is (0,32).

Put y=0, to find the x-intercept.

0=-x^2+4x+32

0=-x^2+8x-4x+32

0=-x(x-8)-4(x-8)

0=-(x+4)(x-8)

x=-4,8

Therefore the y-intercepts are (-4,0) and (8,0).

The vertex of a parabola f(x)=ax^2+bx+c is

(-\frac{b}{2a},f(-\frac{b}{2a}))

-\frac{b}{2a}=-\frac{4}{2(-1)}=2

Put x=2 in the given function.

y=-(2)^2+4(2)+32

y=-4+8+32

y=36

The vertex is (2,36).

Therefore option A is correct.

Please help please help please ​
yKpoI14uk [10]

Answer:

As per Given Information

→ ∠AOB = 7x-99°

→ ∠COD = 2x + 1°

we have to find the value of x .

∠AOB = ∠COD ( Vertically Opposite Angle)

On putting the value we obtain

➺ 7x-99° = 2x + 1°

➺ 7x -2x = 1° + 99°

➺ 5x = 100°

➺ x = 100°/5

➺ x = 20°

So, the value of x is 20° .
