Answer:
b could be -1 or 0
Step-by-step explanation:
f(x) = 3x^2 +bx+2
if it has no real roots, the discriminant must be less than zero
b^2 -4ac <0
a=3 b=b c=2
b^2 - 4(3)(2) <0
b^2 - 24 <0
b^2 < 24
Taking the square root of each side
b< 2 sqrt(6) and b > 2 sqrt(6)
b could be -1 or 0
The total restaurant bill for food and drinks is = $63.57
This total bill consists of the prices of the items purchased, and the tip given to the waiter. So, the total bill of only food will contain only the food prices. So, it will be less than $63.57
Now, as it is not mentioned how much tip was given, lets assume that the tip is 10% which is $ 6.357
So, lets subtract it from the total bill. Its $ 57.22. Hence a good estimation is a reduced bill than the given amount of $63.57
A=pi(r)^2
We have the diameter. To get the radius divide it by 2.
The radius now is equal = 13.
Pi=3.14
Distribute it to the equation... A=3.14(13)^2
The area is equal = 530.66
Answer:
$57.12
Step-by-step explanation:
47.60(1.20)=$57.12
Hello.
The answer is choice A. angle 1 = 118, angle 2 = 118
Explanation:
The four angles above are congruent (meaning the same) to the ones beneath.
Angles 1 and 2 are also congruent, so they will measure the same.
Lets label the angles above A, B, C, D. B being the known angle, which is 118°. The angles beneath can be labelled E, F, G, H.
∠B ≅ ∠D
∠ABCD ≅ ∠EFGH
∠BD ≅ ∠FH
FH (or 1 and 2) equal 118.
