For all those people who forget things -pls eat almonds , almonds will increase your memory!

You can use the on-site calculator that's on th home page for this! It's very helpful I'm sure it'll help u too!

Life's going good! Struggling with exams! Nothing else! How's yours !

One method of converting a fraction into a decimal is dividing the fraction's numerator (the top number) by its denominator (the bottom number). If you want to convert 3/8 into a decimal, divide 3 by 8 = 0.375.    Hope this helps :)

Yes. Yes it is.

Yes. Yes it is.

-4x + 6x = 2x

10+13=23

2x+23=-6

-6-23=-29

2x=-29

-29/2=-14.5

x=-14.5

find an equation of the line. write the equation using function notation. through (7,-3) and perpindicular to 9y=x-18.

$$9y=x-18 \quad \small{\text{ or }} \quad
y = \frac{1}{9}x - 2 \quad \small{\text{ the slope = }} m = \frac{1}{9}$$

$$\small{\text{the slope of the perpindicular line = }}
m_{\perp} = -\frac{1}{m} = -\dfrac{1}{ \frac{1}{9} } = -9$$

$$\small{\text{the function of the perpindicular line = }}
f(x) = y = m_{\perp}(x-x_p)+y_p$$

$$\\\small{\text{with point }} x_p = -3 \small{\text{ and }} y_p = 7 }} \small{\text{, }}
f(x) = y = -9 [x-(-3)]+7 \\
y= -9(x+3)+7 \\
y= -9x-27+7 \\
\boxed{y= -9x -20}$$

its like that:

5!=5*4*3*2*1=120

4!=4*3*2*1=24

26!=26*25*24*23*22*21*20*19*18*..............*3*2*1=......

Yes. I know that. I just forgot... To post it down...

Yes but Sydney is 3am the next day!

Thank you!

Let load on front axle be L

Net upward force = 3L

Net downward force = W + 3000g  (g+9.8m/s²)

W + 3000g = 3L   ...(1)

W acts a horizontal distance (1/2)(4.32 + 2.16/2)m = 2.7m from the back of the cab; so take moments about the back wheel:

Clockwise:  W*(3.6 - 2.7) + 3000g*(3.6 + 0.6)  = 0.9W + 12600g

Anticlockwise: L*(1.8 + 0.6 + 3.6) = 6L

Equate these (assuming the truck is stable!)

0.9W + 12600g = 6L  ...(2)

Now you have two simultaneous equations which you can solve for W and L.

I'll leave you to do this.

Alas I read Standard Times, it said that it was 12:00 Noon at New York City, 9:00 AM in Los Angeles, and 3:00 AM at Sydney.

Because -(1 - 3x) is the same as -1*(1 - 3x), which is -1*1 + (-1)*(-3x)

-1*1 is -1 

(-1)*(-3x) = +3x (two minuses make a plus)

So -(1 - 3x) is the same as -1 + 3x (or 3x - 1, which is the same thing with the order changed)

It is a koala.

1.  Write it as $$\frac{6.7\times 6\times 10^{-11}\times 10^{24}}{6.4^2 \times (10^6)^2}$$

2.  Now as $$\frac{6.7\times 6 \times 10^{13}}{6.4^2 \times 10^{2*6}}$$

3.  Now $$\frac{6.7\times 6 \times 10^{13-12}}{6.4^2}$$

4. Now $$\frac{6.7 \times 6 \times 10}{6.4^2}$$

5. Now $$\frac{67*6}{6.4^2}$$

6. Now calculate 67*6/6.4² = 9.81445...

You have to ensure the powers of ten are the same.  For example:

2*10⁴ + 3*10⁵

Express this as 

0.2*10⁵ + 3*10⁵

Now you can add:

3.2*10⁵

x(1-3x) + 3x-1

=-x(3x-1) +(3x-1)

=(3x-1)-x(3x-1)

=(3x-1)(1-x)

Write it as x(1-3x) - (1-3x) and you can see that (1 - 3x) can be extracted, so it factorises as (1-3x)(x-1)
