988 i believe all i did was add the foreign only up
Answer:
$22.33
Step-by-step explanation:
A 20% tip would be 0.20. Multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total amount including tip.
subtotal --> $18.61
tip --> $3.72
18.61 x 0.20 = 3.72
total --> $22.33
Answer:
Matha - Jim = 200 feet.
Step-by-step explanation:
<em><u>Jim's distance</u></em>
J = sqrt(w^2 + L^2)
J = sqrt(300^2 + 400^2)
J = sqrt(900 + 1600)
J = sqrt(2500)
J = 500
<em><u>Martha's distance</u></em>
M = 300 + 400
M = 700 Feet
Answer
M - J = 700 - 500 = 200
Jim walks 200 feet less than Martha.
Trinomial 2x² + 4x + 4.
It's of the form ax²+bx+c and it's discriminant is Δ=b² - 4.a.c
(in our case Δ = 4² - (4)(2)(4) → Δ = - 32
We know that: x' = -1 + i and x" = -1 - i
If Δ > 0 we have 2 rational solutions x' and x"
If Δ = 0 we have1 rational solution x' = x"
If Δ < 0 we have 2 complex solutions x' and x", that are conjugate
In our example we have Δ = - 16 then <0 so we have 2 complex solutions
That are x'= [-b+√Δ]/2.a and x" = [-b-√Δ]/2.a
x' =
