How would one distinguish an alternate phyllotaxy from a distichous phyllotaxy? Thanks.

Here is the equation:

Any help on factoring this equation?

If k, n, x, and y are positive numbers satisfying x^(-4/3) = k^-2 and y^(4/3) = n^2, what is (xy)^(-2/3) in terms of n and k?

I continually keep on getting n/k but the answer is 1/nk how would i get to that?

h(t) = c - (d - 4t)^2

At time t = 0, a ball was thrown upward from an initial height of 6 feet. Until the ball hit the ground, its height, in feet, after t seconds was given by the function h above, in which c and d are positive constants. If the ball reached its maximum height of 106 feet at time t = 2.5, what was the height, in feet, of the ball at time t=1?

Answer is 70, but how would i get to this?

Figure-- in additional details

The points are: A(-1/2,a), B(-1/2,b), C(1/2,c), D(1/2,d)

In the figure above, ABCD is a rectangle. Points A and C lie on the graph of y=px^3, where p is a constant. If the area of ABCD is 4, what is the value of p?

The answer given is 16, but how would i get to this answer?

If a,b,c, and f are four nonzero numbers, then all of the following proportions are equivalent EXCEPT

a) a/f = b/c

b) f/c = b/a

c) c/a = f/b

d) a/c = b/f

e) af/bc = 1/1

the answer is a) a/f = b/c

my question is how would i get to finding that answer?

1. Doug's biology experiment involved timing 12 hamsters in a maze. Each hamster received at least one practice before being timed. The scatterplot above shows the time each hamster took to complete the maze and the corresponding number of practices that each hamster received. Based on the data, which of the following functions best models the relationship between t, the number of seconds to complete the maze and p, the number of practices?

a) t(p) = 44

b) t(p) = p

c) t(p) = 44p

d) t(p) = p/44

e) t(p) = p + 44

the answer given is A [t(p)=44], how would i get to that answer?

THis is the figure given: ( the thing on top of the arrow is sqrt x )

1. On the number line above there are 9 equal intervals between 0 and 1. What is the value of x?

the answer given is 4/9

what is the solution to get that answer?

1. Let the function f be defined by f(x) = x+1. If 2f(p) = 20, what is the value of f(3p)?

the answer is 28, my question is how to get to this answer

2. http://i40.tinypic.com/mii99v.jpg <-- graph

The figure above shows the graph of a quadratic function f that has a minimum at the point (1,1).

If f(b) = f(3), which of the following could be the value of b? the answer is -1 but how would i get to this answer

Any help or tips on these and functions in general, they confuse me a lot. thanks

Prove:

cotA + tan2A = (cotA)(sec2A)

any help?

Solve the following equations for 0 degrees < x < 360 degrees (its greater and less than or equal to)

cos2xcosx=sin4xsinx

any help would be appreciated

when 7x^2-28x-5 is written in the form a(x-h)^2+k, k=?

so its like converting a standard form equation to vertex form(right?)

so i try to do axis of symmetry and get 2, what would this represent in the 2nd equation?

any help on solving this? thanks

x=√2+√2+√2+..... (all under 1 square root, so first √ is the main one, the next √ would be under the former √ , the third √ under the 2nd √ etc.)

√y+√y+√y+....=5

how would i solve for x or y, its somewhat confusing any help?

R.../ \

X../__\....Y (letters are the vertices of the two triangles)

S./___\...T

in the figure, triangleRXY ~ triangleRST the area of RXY is 24cm^2 and the area of RST is 54cm^2. If lineXY is 10 cm, find length of line ST.

(i can get the height and the hypotenuse of RXY, but how would i relate that to RST to find the answer?)

any help thx.

Find the area of an equilateral triangle inscribed in a circle with a circumference of 64(pi) cm

the book says the answer is 768 sqrt3, how would i get to this answer. All i got to do was to get the radius which is 32 cm, but then after this how would i get the area of triangle???? any help thx

If the product of three consecutive integers written in increasing order equals the middle integer, what is the least of the three integers?

apparently the answer is -1, but i dont get how i would get that answer

what i did is:

x(x+1)(x+2)=(x+1)

[x(x+1)(x+2)/(x+1)]=(x+1)/(x+1)

x(x+2)=1

x^2+2x=1

x^2+2x-1=0

then i cant get how i would get -1

im probably doing it wrong, so any help?

The triangle ABC has vertices A(2,1), B(12,2) and C(12,8). Find the perpendicular distance from B to AC???

The coordinates of ABC are A(1,5), B(4,4) and C(8,6). Given that P is the foot of the perpendicular from A to BC find the coordinates of P and equation of AP

i tried to use the midpoint formula for P but got it wrong the book says the answer is (2,3)

how would i solve this

{n root[(2^n-1)(x^2n-3)(y^n+5)]} / {[2n root[(2^n+2)(x^3n-1)(y^2n+3)]}

this is it in written form:

How would I simplify it???

A boat travels three times as fast when it is empty as when it is full. If it travels 20 km north with cargo, spends 2 hours unloading and returns to the original port empty, taking 8 hours to complete the entire trip, what is the speed of the barge when empty.

the book says the answer is, less than 15kph but not less than 10kph

How would i get about getting this answer???
