Please the attached file for the answer. I hope that helps
<span>1. </span><span>DP , you mean decimal points?
87.6564 is already written in decimals points.
it is a combination of a whole number and a decimal points.
=> 87 is the whole number where 8 is tens and 7 is the ones.
=> 6564 is the decimal numbers where 6 next to the decimal point is tenths,
5 is hundredths, 6 is the thousandths and 4 is the ten thousandths.
When you round this number to its nearest tenths, it becomes 87.7</span>
It's A because 7.5 is the starting point but it's not included so that point is circled.
Answer: $13.95
50%+ of 9.30 is 13.95 (if you do the math)
Answer:
see below
Step-by-step explanation:
y=x^2-4x-12
Set equal to 0 to find the zeros
0 =x^2-4x-12
Factor. What 2 numbers multiply to -12 and add to -4
-6*2 = -12
-6+2 = -4
0= (x-6) (x+2)
Using the zero product property
0=x-6 0 = x+2
x=6 x = -2
zeros: -2,6
Vertex
h = -b/2a = - (-4)/ 2(1) = 4/2 = 2
OR Average the roots (-2+6)/2 = 4/2 =2
The y coordinate is found by substituting into the equation
y = (2)^2 -4(2) -12
y = 4-8-12
y =-16
vertex : (2, -16)
