    What kind of mileage did Magellan get? About 25,000 miles to the Galleon!

  • Help calculus?

    Best answer: x= 3-4t
    4t = 3-x
    t = (3-x)/4

    y= 2-3t
    3t = 2-y
    t = (2-y)/3

    t = (2-y)/3 = (3-x)/4
    4(2-y) = 3(3-x)
    8 - 4y = 9 - 3x
    4y - 8 = 3x - 9

    y = (3x-1)/4

    The curve is a line with slope 3/4 and y-intercept -1/4

  • If x-1, x+2, and x+4 are factors of a polynomial p(x), which of the following must be equal to 0? A) p(-2) B) p(-1) C) p(2) D) p(4)?

    Best answer: If p(x) = (x-1)(x+2)(x+4) = 0
    then either
    .....(x-1) = 0 or
    .....(x+2) = 0 or
    .....(x+4) = 0 or
    .....(x-1) = (x+2) = (x+4) = 0

    If (x-1) = 0 ⇒ x = 1
    If (x+2) = 0 ⇒ x = -2
    If (x+4) = 0 ⇒ x = -4

    So if x= -2, p(-2) = 0.................ANS (Option A)

    Best answer: No, not by birth, Where die the genes for A type blood come from. It is that She's RH negative, because both of her parents can be hetorozygous for Rh,,but one both parent had to have A type blood.. The may have been heterozygous for A type blood, but one birth parent HAD to have a A type blood., because the parent who has the positive blood heterozygous, one of that parents parents was blood type O and have been heterozygous for TH negative blood..

    MY mother and was AB positive and her mother was A positive, I an B negative, so my maternal grandfather had to be B negative too, My father was ) positive, but had to have been heterogeneous for RH. My father's mother was O positive. She turn 41 years old 8 months later the year he was born and hew was born at home with no complications. That means my father's father was o negative.

    Yes, your mother really can be your grandparents daughter.She inherited Rh negative genes from from BOTH of her parents because they were both heterozygous for Rh.

    https://www.stat.washington.edu/thompson/Genetics/1.3_genotypes.html

    My mother had my blood typed twice, just to double check I really am Rh negative. I have not had children, and now I am way too old to have children..

    Best answer: I am aware of no geometric method to derive a precise value for the height, but I can offer an estimate. It involves some speculation, but it certainly is not purely speculative.

    The face turned to the viewer's left appears to be slightly broader than it is tall, and that clearly is the short side of the building. So let the height be about 20 meters.

    The building is five stories high, with the ground floor no taller than the others. That 20 m estimate would come to 4 m per story. That seems a bit high by modern standards, but from the style it appears that the building was erected before 1950, when high ceilings were more common. I will stick to the 20 m estimate.

    Best answer: Remember the right triangle? And how we can figure out the legnth of the sides?

    Einstein was able realize that if he squared the Speed of Light C, he could use the Pythagorean Theorem to bring together the relationship between Light, Mass and Energy using a^2+b^2=c^2

    Once you watch the video, you realize all the sides of a triangle depend on each other, just like light, mass and energy. And you can't have a right triangle that has more than the sum of the other two sides. If, for example, C is infinite, then the and b sides are infinite too.


    This is so incredible I would get would get a tattoo of this on my arm, easily one of the most incredible things is that it took from Pythagorus 3000 year ago, to Einstein to see this.
