H(x) = -x² - 4
i(x) = 2x + 3

h(i(5)) = -(2(5) + 3) - 4
h(i(5)) = -(10 + 3) - 4
h(i(5)) = -(13) - 4
h(i(5)) = -13 - 4
h(i(5)) = -17

Find the co-ordinates of the vertex of the function y=x²-12x+2 and show your work
nataly862011 [7]

Answer:

(6,-34)

Step-by-step explanation:

You can use the vertex formula to find the x of the vertex and then plugin the x value into the formula to find the y value.

x = -\frac{b}{2a}

x = -\frac{b}{2a}

x = -\frac{-12}{2(1)}

x = 6}

Now plugin 6 into  y=x²-12x+2

y=x²-12x+2

y=6²-12(6)+2

y=36-72+2

y=36-72+2

y = -34

Vertex = (6,-34)

The value of______ divided by 40.01 is close to 1
guapka [62]

The value of 39.6099 divided by 40.01 is close to 1.

Solution:

Given data:

The value of______ divided by 40.01 is close to 1.

close to 1 means not exactly one which is 0.99.

Let the unknown be taken as x.

x ÷ 40.01 = close to 1

x ÷ 40.01 = 0.9999

$\frac{x}{40.01} =0.99

Do cross multiplication, we get

x =0.99\times40.01

x = 39.6099

Hence the value of 39.6099 divided by 40.01 is close to 1.
