Very nice, Dragonlance........

We can use the tangent inverse to solve this....so we have

tan^-1(400/300) = about 53.1°  [ this is the angle of depression]

Expand (X+7)(x-1)

=x^2+6x-7

Expand (x+1)^2

=x^2+2x+1

Then write this

x^2+6x-7=x^2+2x+1

subtract this from both sides x^2+2x+1

That leave this.

4x-8=0

Then

4x=8

Divide by 4

This is the answer

X=2

3x^2  = 4x + 4    I assume you want to solve this

Move everything on the right to the left side and set the right side = 0   so we have

3x^2 - 4x - 4 = 0    factor

(3x  + 2) (x - 2 )  = 0     and setting each factor to 0, we have that x = -2/3  and x  = 2

CPhill explain it to you. It is PEMDAS. Calculators use that

62 ÷ 3 • 2 + √9 =27

If you put it in your calculator like this with parentheses

62 ÷(3 • 2) + √9 =9

Then it = 9.

Don’t believe the dumbshit anon.

27 is correct!!!

The problem is written like this

6² ÷ 3 • 2 + √9

Answers on homework are

A. 27    B. 9   C. 2.4   D. 60

I went with B but, When I inputed that formula in my scientific calculator I also got 27

6^2/3*2+ sqrtof9   using PE (MD) (AS)   we evaluate the exponent, first....so we have

36/3*2  + sqrt(9)   now, we perform any multiplications/divisons we encounter from left to right

We first encounter a division  (36/3), so we do that next and we have

12*2 + sqrt(9)    now, perform the multiplication

24 + sqrt(9)  and we have

24 + 3   =

27

NO, there is only ONE right answer, which is 9. If you start from the left & reduce that, you will only get 6 + the right hand side, which is 3=9. Very easy, right.

If it look like the way you write it then the answer is 27

If it was like this

6^2/(3*2)+sqr(9)

then the answer is 9

I did get 9 but I double checked in my calculator and I also got 27 which is another answer on this homework it's multiple choice...

6^2/3*2+ sqrtof9

Well, what's 6 x 6=36

What's 3 x 2=6

you divide the 1st. by the 2nd. and you get,

36 /6 =6

What is square root of 9? It's 3, right.

Then just add, 6 + 3=9

YOU THINK YOU CAN DO THAT IN YOUR HEAD? JUST TRY IT.

Y=(T+6)/x   multiply both sides by x

xY  = (T + 6)    divide both sides by Y

x = (T + 6) / Y

Remember that something squared is just that thing times itself....so we have

(x + h)^2   = (x + h) (x + h)  = x^2 + 2xh + h^2

It is negative if you look at the force from the spring. It is positive if you look at the force from gravity. 

NEITHER!!. Both are wrong!

It not either one.

It is this. x² +2xh +h²

i think i'll be fine, but i'll post back if i get stuck.

If you get stuck, ragg3dly....post back....I haven't heard of the "diamond" method before, but....I think I could walk you through it......

ok thank you... i need to go on this site more often 

Here's a website that might help you with this: http://www.robertshady.com/content/diamond-problem-solving-quadratic-equations-dummies

49,47,52,50,55

The pattern for the successive terms after the first term is  -2, +5, -2, +5.....etc.

oh duuhh thanks 

49,47,52,50,55,

The patern appears to be: -2, +5, -2, +5............etc.

1/4 + 2/5=5/20 +8/20=13/20
