No no and no ! LOL

i guess my profile picture isn't very clear.

It's a raspberry.

I like to make stuff and do DIY electronics.

The raspberry pi SBC is one of my favorite computers and this is the logo that the company producing them uses.

And also it happens one of my favorite fruit is a raspberry LOL.

The the neaerest tenth of a cubic foot, the volume is 34.1.

1. AC = 6

2. XY = 4/9.

The possible values of 1, 2, and 4, giving us three possible values of x.

There are 5 solutions.

According to my calculator

tan 3            =     0.0524 

tan 30          =     0.5774 

tan 300        =   –1.7321

tan 3000      =   –1.7321 

tan 30000    =   –1.7321 

   _.

thats also wrong

Vertex: \([\dfrac{-b}{2a},f(\dfrac{-b}{2a})]\)

you already know that a = 4, b = -6, c = 15

all you have to do from here is plug in the values!

The 'x' coordinate of the vertex will be found by   - b / 2a          a = 4    b = -6    c = 15

   plug this value into the equation to find the 'y' coordinate.....

This is from the counting and probability course right guest?

All credit for my answer goes to aops

Marvin needs to take 5 right moves out of a total of 12, so ignoring the frog there are 12 choose 5 = 792 possible paths to 5,7.

The number of paths from 0,0 to 5,7 passing through 4,3 is the number of paths from 0,0 to 4,3 multiplied by the number from 4,3 to 5,7 , which is 7 choose 3* 5 choose 1 =175. There are thus 792 - 175 = 617 ways that Marvin can reach his destination.

This is the aops explanation.

2x - 9y = 14

y = -42 +6x

2x - 9 (-42 + 6x) = 14 

x= 7

y= -42 + 6 * 7

y = 0

(x,y) = (7,0)

xy= 0

Thank you so much!

Possible committees     10 C 3  =  10!/(3!7!) = .....

With Mark already on the committee  you have one position filled and need to

A sequence is defined by a_{n + 1} = a_n + 2n, and a_1 = 4. 

This recursion can be written as:  a_n = a₁ + (n-1)*n

You can easily obtain a₇ + a₈ from this.

Nine points are evenly spaced on a standard number line. They are labeled A through I, from left to right. The coordinates of points A and I are 1 and 10, respectively. What is the coordinate of point B?...

Nine points have eight gaps.   Hence A to B is a distance of (10 - 1)/8  = 9/8.

Coordinate of B  = coordinate of A + 9/8

I'll let you finish.

Thx dude 

And.. What about you, hugo? 

-Are you grapes?
-Is your favourite food grapes?
-Are you white, purple or green in real life? 

A bag contains five white balls and four black balls. Your goal is to draw two black balls....

If the two coefficients of the highest order terms of both polynomials have the same sign, then the sum is also a 7th degree polynomial.

If the highest order terms have coefficients that are of equal magnitude but opposite sign, then the sum would be a polynomial of lower degree.

If the two polynomials are, say, f(x) = ax⁷, and g(x) = -ax⁷, then the sum is zero, so the product of the degrees would be zero.

Assuming this is not the case and we have, say, f(x) = ax⁷ + bx + c, and g(x) = -ax7 + dx + e, then the sum is of first degree and the product is 7.

(The above assumes I've interpreted the question correctly!).

The Candle Company is designing a new cylindrical candle. They are looking at four different molds. Which mold will use the least amount of wax?

oh thanks :)

Replace P in the second equation by 3K - 10 (from the first equation) then rearrange to get K.
