Can anyone help me with this, i just want to make surr i have it right. (20-4)×12-6. Does it equal 96 or 186
expeople1 [14]

196, because 20-4 equals to 16 and 16 times 12 equals 192, and 192 minus 6 is equal to 186.

A tree's height increase by 15%. If a tree is 23 feet high, how tall will it be in one year ?
Ghella [55]

Increased height:-

\\ \sf\longmapsto 23\times 15\%

\\ \sf\longmapsto 23\times \dfrac{15}{100}

\\ \sf\longmapsto \dfrac{345}{100}

\\ \sf\longmapsto 3.45

Now current height:-

\\ \sf\longmapsto 23+3.45=26.45ft

The axis of symmetry for a function in the form f(x) = x2 + 4x − 5 is x = −2. What are the coordinates of the vertex of the grap
Studentka2010 [4]

Answer:

D) (-2,-9)

Step-by-step explanation:

<u>Vertex Form of a Vertical Parabola:</u>

y=a(x-h)^2+k

Vertex -> (h,k)

Axis of Symmetry -> x=h

Vertical Scale Factor -> a

  • To turn f(x)=x^2+4x-5 into vertex form, we need to complete the square on the right side
  • Therefore, if f(x)=0, then 0+9=x^2+4x-5+9 completes the square on the right side
  • This becomes 9=(x+2)^2
  • This means that our function in vertex form is f(x)=(x+2)^2-9

Therefore, the vertex of the graph is (h,k)=(-2,-9).
