Answer:
x^2 + px + q = 0
x = - p/2 ± √((p/2)^2 - q)
x^2 - 4x + 3 = 0
x = - (-4)/2 ± √(((-4)/2)^2 - 3)
x = 2 ± 1
x1 = 1
x2 = 3
Each loop is of a different size, so we can't rotate the figure some angle x to have it line up with itself (0 < x < 360). Therefore, it doesn't have any rotational symmetry. That rules out choice A and choice C. Point symmetry is the same as saying "rotational symmetry of 180 degrees"
The figure doesn't have any line symmetry either. There is no line we can draw and reflect the figure over to have it match up with itself. That rules out choice B and points to choice D
Answer: D) It has no reflectional symmetry.
Answer: each bottle costs $0.91
Step-by-step explanation: the total amount (before tax) is $5.49, we already know that one bag of apple was purchased for $1.85 so we can subtract that from the total. $5.49-$1.85=$3.64 Four bottle of juice were purchased so we can divide $3.64 by 4 which equals $0.92
If the inscribed square has sides of 8in, the diameter of the circle is equal to the diagonal of the square.
d^2=x^2+x^2
d^2=2x^2
d=√(2x^2)
Since d=2r, r=d/2 so
r=(1/2)√(2x^2)
r=√((2x^2)/4)
r=√(x^2/2), since x=8
r=√(64/2)
r=√32
r=√(16*2)
r=4√2 in (exact)
r≈5.66 in (to nearest hundredth of an inch)
Answer:
(B)5
Step-by-step explanation:
7/11plus 5 on the numerator and denominator will give u 12/16 when it simplified ...it will give u 3/4.
