The figure below shows rectangle ABCD with diagonals segment AC and segment DB: A rectangle ABCD is shown with diagonals AC and BD. Anastasia wrote the following proof to show that the diagonals of rectangle ABCD are congruent:
Anastasia's proof:
Statement 1: Rectangle ABCD is given
Statement 2: segment AB ≅ segment DC because opposite sides of a rectangle are congruent
Statement 3: segment AD ≅ segment AD by the reflexive property of congruence
Statement 4:
Statement 5: Angles BAD and ADC are congruent because all right angles are congruent
Statement 6: Triangles BAD and CDA are congruent by SAS Statement 7: segment AC ≅ segment DB by CPCTC
Which statement below completes Anastasia's proof?
A. Angles BAD and ADC are 90 degrees (perpendicular lines create 90-degree angles)
B. Angles BAD and ABC are 90 degrees (perpendicular lines create 90-degree angles)
C. Angles BAD and ADC are both right angles (definition of a rectangle)
D. Angles BAD and ABC are both right angles (definition of a rectangle)

answer: the answer is simply nothing.

step-by-step explanation: because there is no ending to this question

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

step-by-step explanation:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
