Answer:
The location of the point that is 3/4 the distance from is .
Step-by-step explanation:
Let and the endpoints of the segment, we can determine the location of the point that is 3/4 the distance from by the following vector equation:
(1)
If we know that and , the location of is:
The location of the point that is 3/4 the distance from is .
Answer:
Step-by-step explanation:
A complex number is defined as z = a + bi. Since the complex number also represents right triangle whenever forms a vector at (a,b). Hence, a = rcosθ and b = rsinθ where r is radius (sometimes is written as <em>|z|).</em>
Substitute a = rcosθ and b = rsinθ in which the equation be z = rcosθ + irsinθ.
Factor r-term and we finally have z = r(cosθ + isinθ). How fortunately, the polar coordinate is defined as (r, θ) coordinate and therefore we can say that r = 4 and θ = -π/4. Substitute the values in the equation.
Evaluate the values. Keep in mind that both cos(-π/4) is cos(-45°) which is √2/2 and sin(-π/4) is sin(-45°) which is -√2/2 as accorded to unit circle.
Hence, the complex number that has polar coordinate of (4,-45°) is
Problem: 4/5, which is 4 / 5.
Step-by-step explanation:
To solve this problem, we must divide 4 and 5.
4 / 5 = 0.80
Answer: 0.8, 4/5.
Another way is to change 4/5 into a Decimal.
It's 0.8 because Four (Fifths), If you multiply 4 / 5, both terms by 2, you get 8/10 and you write it as a decimal of 0.8
Eight - Tenths.
Last Way:
Change into a decimal be comparing other fractions,
8/10 = 4/5 and 8 / 10 has a decimal of 0.8.
Hope this helps!!
Answer:
The product of 9.2 and 7.81 will be 71.852 so it has three decimal places.
Step-by-step explanation:
9.2 X 7.81 = 71.852 ( 3 decimal place figure)
