This is the concept of quadratic equations, solving the equation 2x^2-12x+20=0 using the formula we get:
x=[-b+/-sqrt(b^2-4ac)]/(2a)
from our equation, a=2,b=-12 and c=20
x=[-(-12+/-sqrt((-12)^2-4*2*20)]/(2*2)
x=[12+/-sqrt(144-160]/4
x=[12+/-sqrt(-16)]/4
x=[12+/-4i]/4
x=[3+\-i]
the answer is A] 3+/-i
I believe the answer would be(A) Radius (air)=3
Answer: I believe the answer is b.
Answer:
36 in
Step-by-step explanation:
7+7+11+11= 36
Given:
The recipe calls for 0.5 quart of milk and 2.5 cups of flour.
She has
quart of milk and
cups of flour.
To find:
Whether she have the correct amount of milk and flour to make the pancakes from the recipe.
Solution:
Required Milk = 0.5 quart
Milk she has =
quarts
Clearly, 0.375 < 0.5.
Required Flour = 2.5 cups
Flour she has =
cups
Clearly, 2.25 < 2.5
Since, the amount of milk and flour she has is less than the required amount, therefore she does not have the correct amount of milk and flour to make the pancakes from the recipe
