Answer:
f(x) = 2(x -3)² +5
Step-by-step explanation:
For vertex (h, k) and scale factor 'a', the vertex form is ...
f(x) = a(x -h)² +k
We can fill in the values of h and k from your vertex, and use the values of the extra point to find 'a'.
55 = a(-2 -3)² +5
50 = 25a . . . . . . . . subtract 5
a = 2 . . . . . . . . . . . divide by 25
So, the function is ...
f(x) = 2(x -3)² +5
__
In standard form, that will be ...
f(x) = 2x² -12x +23
Answer:
x=2.600
Step-by-step explanation:
2x(x+4)+7+=(x+8)+ 2x(x+1)+12
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-> 2*x*(x+4)+7+-((x+8)+2*x*(x+1)+12)=0
-> ((2x•(x+4))+7)-(((x+8)+2x•(x+1))+12) = 0
-> (2x • (x + 4) + 7) - (2x2 + 3x + 20) = 0
-> 5x - 13 = 0
-> Add 13 to both sides of the equation :
5x = 13
Divide both sides of the equation by 5:
x = 13/5 = 2.600

Answer:
10.5 cm^2
Step-by-step explanation:
Since we have two sides and the angle between those sides, we can use the alternative area formula:
a and b are the two sides while C is the angle in between the two sides.
Plug in the numbers:
Recall the unit circle. Sin(150) is 1/2.
