An isosceles right triangle ABC, point D is on hypotenuse line BC such that line AD is an altitude of triangle ABC and DC = 6. What is the area of triangle ABC?

Area = 6²

1 - 360 - 91 - 92 - 93 =?

2 - The number is: 43 / 42

4 - Divisors of 19,571,123 =  (1, 11, 13, 143, 136861, 1505471, 1779193, 19571123) >>Total = 8

[1,  11,  13] = 3 divisors below 16

5 - Not Clear Enough. Write your numbers clearly !! 

Let a and b be digits. What is the largest four-digit number a47b that is divisible by 36?

The largest 4-digit number =5472 [This is divisible by 2 AND 3 and their multiples of 4, 6, 9, 12 and 18].

(x+1)^2+(y-1)^2  = 3^2 + 2^2     expand and re-arrange

Press "2nd" key up the top left-hand corner. Then you should see the "Mod" key next to "C" , to the right.

x=0;p=0; y=0;z=0;n=gcd(y, 60);m=lcm(y, 60);if(n==x+5 and m==x*(x+5), goto loop, goto next);loop:p=p+1;printp," =",x,y;next:x++;if(x<200, goto4,0);x=0;y++;if(y<200, goto4, 0)

x = 15.  Your two integers are: 60  and the smallest possible value of the 2nd integer = 100.

GCD[60, 100] =[x + 5] =[15 + 5] = 20

LCM[60,100] =x[x + 5] =15*[15 + 5] =15 * 20 =300

\(250 - 167.93 = $82.07\)... 

re-arrange to  (x+6)^2 + (y-2)^2  = 53       circle with r^2 = 53

area = pi r^2   = 53 pi  

*** edit ***     a= - 1.778

-b/2a = -3      and  a(-3^2) + b(-3)+c=5    and    a(0) + b*0 +c = -11     so c = -11

b/2a = 3                     9a -3b =16

a =b/6                        9 (b/6) -3b=16      b = -10.667      a =1.778

.......   m = -82.111

1.  The answers are yes, yes, no, no.

2. The answers are no, yes, no, no.

Question is very unclear:

2⁴ * 2n = 32n

2⁴ *2ⁿ = 2⁴⁺ⁿ

2^4*2n= 2⁸ⁿ

There are 156 triples.

Question 2e 4 times 2n please provide what the end anser is (something n)   

Seriously?  4 x 2n = 8n 

_.

How many pairs of vertical angles are formed by five distinct lines that have a common point of intersection?   

No need for mathematical formulae here.  Just draw it and count them.  FIVE

1. We can find the slope of the line: (-3-7)/(5-(-2)) = -10/7.

2. Plug in the point (3,a) to find the slope: (-3-a)/(5-3) = -10/7.

3. Cross multiply to get the equation: -20 = -21 - 7a.

This gives us -1/7 = a.

Hope this helped!

This has been answered before by CPhill (along with another question): https://web2.0calc.com/questions/2-problems

I hope this helped!

There are 3 cool triples.

Real values of

\(\sqrt[4]{324}\) =  - +4.24264

by pythagorean theorem

AB = sqrt (2^2 + 6^2)                        This figure is obviously not to scale !

3 is 5/7 of the way from -2 to 5

-1/7  is 5/7 of the way from 7 to -3      a = -1/7

Do you understand it?

Do you have any questions about what I have written?

Will you be able to do these by yourself in future?
