3.75 is the answer.
Thank you!
1. The equation of the parabola is y = 1/3*x^2 - x + 4/3, so abc = (1/3)(-1)(4/3) = -4/9.
3. y = -2x^2 + 8x + 15
(complete square) y = -2(x - 4)^2 + 47 ==> vertex = (4,47)
Here is a formula... (a+b)(a-b)=a^2-b^2
So, let's use that formula here!
\((sqrt(23)+sqrt(5))(sqrt(23)-sqrt(5))\)
would equal (sqrt(23))^2 - (sqrt(5))^2
This is equal to 23-5, which is 18.
HINT: find the slope of the 2 points then plug tht into the formula y=mx+b, m=slope
then plug in the y and x using any ofthe 2 pointsandsolve for b then add them.
please help!
The answer is 16pi.
r = 9 BC = 10 DE = 3
CI = sqrt( BI2 - BC2 ) = 14.96662955
AH = sqrt( AE2 - HE2 ) = 4.123105626
EF = AH * 2 = 8.246211251
CD = CI/2 - AH = 3.360209149
∠BDH = arctan( CD / BC ) = 18.57342528º
∠FDI = arctan( DE / EF ) = 19.99156073º
∠BDF = ∠BDH + 90º + ∠FDI = 128.564986º
But 1 isn't right!
The five-digit number 246n8 is divisible by 9. What is the digit n?
n = 7

Sorry, but (3,-2,-12) isn't right.

I think the maximum value is -726.25.
Lets say that this is the equation. \(P=(\square+ \square+ \square+ \square+ \square) (\square+ \square+ \square+ \square+ \square)\)
Now saying that one of those factors is \(x\)
Now when you add up 1+2+3+4+5+6+7+7+9+10, you will get it equal to 55.
So we can say that 55-\(x\) is equal to the other factor.
Now when you multiply those out you get: \(x(55-x)=-x^2+55x\)
Then you get it into vertex form, and when you do so, you will get \(-1(x-27.5)^2-27.5^2\)
We know that 27.5 squared is then the maximum value, so computing that, we get that the maximum is -756.25.
Make the numerator as large as possible : 10 9 8 7 6
and the denominator as small as possibe 1 2 3 4 5
Sorry....the lates just converted to soemthing readable.....
to maximize the product, make the numberes as close together as possible
1 - 10 summ to 55 so 27 x 28
10 7 5 3 2 * 9 8 6 4 1 I suppose... anyone else?
The smallest n = 8
135 * 8 =1080
1080 mod 360 = 0
By the angle bisector theorem, the slope is 2/5.
I think that should be m-2 = 3 and 21
so m = 1 and 19
m =3 and 21
1113 , 1122 , 1131 , 1212 , 1221 , 1311 , 2112 , 2121 , 2211 , 3111 , Total = 10
Probability = 10 / 6^4 = 10 / 1296 =5 / 648 =0.7716%
Bummer......then I do not understand what your question is asking.....
That answer is wrong.
