The percentage is 85 percent
Answer:
C. -7x^2 - 28
Step-by-step explanation:
Firstly simplify the bracket before doing anything;
4x(3x - 7) = 12x^2 - 28x
then go back to the question and substitute the expression(12x^2 - 28x) on the bracket and then work out the question;
12x^2 - 28x -19x^2...then group the values with the same exponent of x,
(12x^2 - 19x^2) - 28x
; -7x^2 - 28x
Answer: OPTION D.
Step-by-step explanation:
The vertex form of a quadratic function is:
Where (h, k) is the vertex of the parabola and "a" is the coefficient of the squared in the parabola's equation.
We know that the vertex of this parabola is at (5,5) and we also know that when the x-value is 6, the y-value is -1.
Then we can substitute values into 
and solve for "a". This is:
110% =1.10
multiply the old price by that
2.85 *1.10 = 3.135
round to 3.14
new price is $3.14
If angle TSV=6x+17 then arc it intercept (SV)would be double it
6x+17=1/2 (15x+13)
12x+34=15x+13
21=3x
x=7
Arc SV=15(7)+13
=118
And angle TSV=6(7)+17
=59
There are 360 degrees in a circle and the measure of the arc would be equal to the central point so the sum of all the arcs equals 360
Arc SV+ arc SUV=360
118+SUV=360
Arc SUV=242
