find the slope of (1/4,1/8) (1/2,3/4)

When Marry 18,

Ann would be what?

9 (half of it) --> 9 years diff

That is so wrong..

How about 16 (Marry),and 8 (Ann) --> 8 years diff.

Now 24 y.o. Marry and 16 y.o. Ann..

Still 8 years diff..

Go figure

A^B=C^D

Find D

\(\begin{array}{|rcll|} \hline C^D &=& A^B \quad &| \quad \ln() \text{ both sides }\\ \ln(C^D) &=& \ln(A^B) \quad &| \quad \ln(a^b) = b\cdot \ln(a) \\ D\cdot \ln(C) &=& B\cdot ln(A) \quad &| \quad :\ln(C) \\ \mathbf{D} & \mathbf{=} & \mathbf{B\cdot \frac{ln(A)}{ln(C)}} \\ \hline \end{array}\)

ln(a*b)/ln(c)

Converting from slope-intercept to standard form

how do I turn this y= 29.95x+99

\(\begin{array}{|c|c|} \hline \text{Slope-intercept form } y = mx+b & \text{Standard form } Ax+By = C \\ \hline \begin{array}{rcll} y &=& 29.95x+99 \qquad &| -29.95x \\ -29.95x + y &=& 99 \qquad &| \cdot 20 \\ -599x + 20y &=& 1980\\ \end{array} & \begin{array}{rcll} \\ \\ -599x + 20y &=& 1980\\ \end{array} \\ \hline \end{array}\)

7/21 in its simplest form. Is it 3/7?

A division is the same a fraction.

To simplify a fraction you have to divide top and bottom by the same thing. 

\(\frac{7}{21}=\frac{7\div7}{21\div 7}=\frac{1}{3}\)

trigonometric ratios

(x+3)^0+x^0-5x^0

\((x+3)^0+x^0-5x^0\\ x\ne3\qquad x\ne0\\ =1+1-5*1\\ =1+1-5\\ =-3\)

(60/sin p)=(65/sin 75)  

[sin p /60 ]= [sin 75 / 65]  

sin p  = [ 60 sin 75 ] / 65 

use the sine inverse   [arcsin ]

arcsin [ [ 60 sin 75 ] / 65 ]  ≈ 63.08° = p

Distance    Origin of Fun: (0, 0)   →    Quadratics in Motion: (-7, 6)

sqrt [ (-7)^2  + 6^2 ]  = sqrt [49 + 36] = sqrt [85]

Distance    Quadratics in Motion: (-7, 6)   →    Towers of Trigonometry: (-2, 14)

sqrt [ (-7 - - 2)^2  + (14 - 6)^2 ]  = sqrt [(-5)^2 + 8^2] = sqrt [25 +  64]  sqrt [89]

Distance     Towers of Trigonometry: (-2, 14) →   The Food Equation: (5, 8)

sqrt [ (-2- 5)^2  + (14 - 8)^2 ]  = sqrt [49 + 36] = sqrt [85]

Distance      The Food Equation: (5, 8) →  Origin of Fun: (0, 0)

sqrt [ (5 )^2  + ( 8)^2 ]  = sqrt [25 + 64] = sqrt [89]

Total Distance  =  60 * [ 2sqrt(85) + 2sqrt(89)]  ≈ 2238 m

The geometric shape is  a parallelogram..... pairs of opposite sides / angles  are equal.......

no it's 3

1/2x-4=-3-1/3x

1.

\(\frac{1}{2}x-4=-3-\frac{1}{3}x\)

\(\frac{1}{2}x+\frac{1}{3}x=-3+4\)

\(\frac{3+2}{6}x=1\)

\(5x=6\)

\(x=\frac{6}{5}=1\frac{1}{5}=1.2\)

2.

\(\frac{1}{2x}-4=-3-\frac{1}{3x}\)

\(\frac{1}{2x}+\frac{1}{3x}=-3+4\)

\(\frac{3+2}{6x}=1\)

\(6x=5\)

\(x=\frac{5}{6}=0.8\overline 3\)

thx

First Multiply -98 and 67 so that would be -6566 and then do 78-6566 = -6488.

I may be wrong but that is what I think.

a cylinder has a height 40ft and a radius of10ft. Can its volume be10 ft ^3? why or why not?

The volume of a cylinder is base area times height.

\(V=\pi r^2h=\pi \times (10ft)^2\times 40ft=12566.371 ft^3\)

When you take the square root of a fraction, it's like taking the square root of the numerator over the sqare root of the denominator.

The first one would be sqrt(17)/6.

The second would be sqrt(20)/9, except that sqrt(20) can be simplified to be 2*sqrt(5).

thanks      maths not math  

It is not 12% it is just 12 :)

dividend ÷ divisor = quotient

Definition Of X and Y intercept?

The x intersept is where the graph crosses the x axis and the equation of the x axis is y=0

so you substitute y=0 inot your equation and the answer will be x intercept

The y intersept is where the graph crosses the y axis and the equation of the y axis is x=0

so you substitute x=0 into your equation and the answer will be y intercept

If it were 7x - 4x, you'd have 3x. Similarly, 7x^3/2 - 4x^3/2 = 3x^3/2.
