Answer:
gallons of ice tea is left with Morris
Step-by-step explanation:
Morris has 2 3/4 gallons of ice tea. He gives 3/7 of it to her friend.
Morris has 2 3/4 gallons of ice tea
He gives 3/7 of it to her friend.
To find how many gallons of ice tea does Morris have left , we subtract 3/7 from 11/4
Make the denominators same
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
