Choose 1 answer: Choose 1 answer: (Choice A) A Ioana used an invalid reason to justify the congruence of a pair of sides or angles. (Choice B) B Ioana only established some of the necessary conditions for a congruence criterion. (Choice C) C Ioana established all necessary conditions, but then used an inappropriate congruence criterion. (Choice D) D Ioana used a criterion that does not guarantee congruence.
Answer:
The answer is Choice C
Step-by-step explanation:
I got it right, look at the screenshot for proof
Answer:
Choice C
Step-by-step explanation:
Writing a proof
A proof is a formal description of how we can know that something is true based on the information from a mathematical scenario.
Each step of the proof is a transformation, a construction, or a statement about what we can conclude from earlier steps.
For a two-column proof we give a reason to justify each statement. Common reasons include geometric theorems, algebraic properties, and information given in diagrams.
Let's check the reason for each step and whether Ioana established the conditions for it.
Hint #22 / 4
Step 1
The diagram does support the claim that PQ=RQ=9PQ=RQ=9P, Q, equals, R, Q, equals, 9.
Step 1 is correct.
Step 2
The diagram does support the claim that m\angle O=m\angle S=90\degreem∠O=m∠S=90°m, angle, O, equals, m, angle, S, equals, 90, degree.
Step 2 is correct.
Step 3
The diagram does support the claim that m\angle PQO=m\angle RQS=63\degreem∠PQO=m∠RQS=63°m, angle, P, Q, O, equals, m, angle, R, Q, S, equals, 63, degree.
Step 3 is correct.
Hint #33 / 4
Step 4
In this step, Ioana claims that \triangle OPQ\cong \triangle SRQ△OPQ≅△SRQtriangle, O, P, Q, \cong, triangle, S, R, Q using the angle-side-angle criterion. But the corresponding pair of congruent sides, \overline{PQ}
PQ
start overline, P, Q, end overline and \overline{RQ}
RQ
start overline, R, Q, end overline, aren't the sides that are included between the two pairs of congruent corresponding angles.
Ioana should have used the angle-angle-side criterion.
Hint #44 / 4
Ioana established all necessary conditions, but then used an inappropriate congruence criterion.

The equation is y=4x-3.
The Pythagorean theorem states that the sum of the squares of the legs of a right triangle is equal to the square of the
hypotenuse by the formula a2 + b2 = c2.
If a is a rational number and b is a rational number, why could c be an irrational number?
O The square of rational numbers is irrational, and sum of two irrational numbers is irrational.
O The product of two rational numbers is rational, and the sum of two rational numbers is irrational.
O The left side of the equation will result in a rational number, which is a perfect square.
O The left side of the equation will result in a rational number, which could be a non-perfect square.
Answer:
The product of two rational numbers is rational, and the sum of two rational numbers is irrational.
Step-by-step explanation:
Let be [tex]a[/tex] and [tex]b[/tex] rational numbers whose forms are, respectively:
[tex]a = \frac{m}{n}[/tex] and [tex]b = \frac{q}{r}[/tex], [tex]m[/tex], [tex]n[/tex], [tex]q[/tex], [tex]r[/tex] [tex]\in \mathbb{Z}[/tex]
We proceed to demonstrate if the Pythagorean sum of two rational numbers leads to a rational number.
1) [tex]a = \frac{m}{n}[/tex], [tex]b = \frac{q}{r}[/tex], [tex]m[/tex], [tex]n[/tex], [tex]q[/tex], [tex]r[/tex] [tex]\in \mathbb{Z}[/tex] Given.
2) [tex]c^{2} = a^{2}+b^{2}[/tex] Given.
3) [tex]c^{2} = \left(\frac{m}{n} \right)^{2}+\left(\frac{q}{r} \right)^{2}[/tex] 1) in 2)
4) [tex]c^{2} = (m\cdot n^{-1})^{2}+(q\cdot r^{-1})^{2}[/tex] Definition of division.
5) [tex]c^{2} = [m^{2}\cdot (n^{-1})^{2}]+[q^{2}\cdot (r^{-1})^{2}][/tex] [tex](a\cdot b)^{c} = a^{c}\cdot b^{c}[/tex]
6) [tex]c^{2} = m^{2}\cdot n^{-2}+q^{2}\cdot r^{-2}[/tex] [tex](a^{b})^{c} = a^{b\cdot c}[/tex]
7) [tex]c^{2} = [m^{2}\cdot (n^{2})^{-1}]+[q^{2}\cdot (r^{2})^{-1}][/tex] [tex](a^{b})^{c} = a^{b\cdot c}[/tex]
8) [tex]c^{2} = \frac{m^{2}}{n^{2}}+\frac{q^{2}}{r^{2}}[/tex] Definition of division.
9) [tex]c^{2} = \frac{m^{2}\cdot r^{2}+q^{2}\cdot n^{2}}{n^{2}\cdot r^{2}}[/tex] [tex]\frac{x}{y} +\frac{w}{z} = \frac{x\cdot z+w\cdot y}{y\cdot z}[/tex]
10) [tex]c^{2} = \frac{(m\cdot r)^{2}+(q\cdot n)^{2}}{(n\cdot r)^{n}}[/tex] [tex](a\cdot b)^{c} = a^{c}\cdot b^{c}[/tex]/Result.
If [tex]c[/tex] is a rational number, then [tex](m\cdot r)^{2}+(q\cdot n)^{2} = a^{2}[/tex], so that [tex]a \in \mathbb{Z}[/tex]. Which means that [tex]c[/tex] will be rational number if and only if the square root of [tex](m\cdot r)^{2}+(q\cdot n)^{2}[/tex] is an entire number.
Which means that correct answer is B.

Item 7 A parabolic spotlight is being designed with the lightbulb at the focus point. If the lightbulb is placed 2.5 inches above the vertex and the height of the spotlight is 10 inches, what is the width of the spotlight? Item 7 A parabolic spotlight is being designed with the lightbulb at the focus point. If the lightbulb is placed 2.5 inches above the vertex and the height of the spotlight is 10 inches, what is the width of the spotlight?
Answer:
The width of the spotlight is 20 inches
Step-by-step explanation:
The location of the bulb = 2.5 inches above the vertex
The height of the spotlight = 10 inches
The width of the spotlight =
The
The height of
The equation of a parabola is given as follows;
(x - h)² = 4p(y - k)
Focus, (h, k + p) = (0, 2.5)
y = k - p
k + p = 2.5
Vertex = (h, k) = (0, 0), therefore, k = 0
p = 2.5
We have;
(x - 0)² = 4p(y - 0)
x² = 4×2.5 × y = 10·y
Therefore, given that y = 10, we have;
x² = 10 × 10 = 100
x = √100 = ±10
The coordinates of the two end points are;
(-10, 10), and (10, 10)
Therefore, the width of the spotlight = the distance between the end points
Given that the y-values are the same, we have
Distance = 10 - (-10) = 10 + 10 = 20 inches
∴ The width of the spotlight = 20 inches.
Determine whether the given value is a statistic or a parameter. A sample of seniors is selected and it is found that 65% own a television. A. Statistic because the value is a numerical measurement describing a characteristic of a sample. B. Parameter because the value is a numerical measurement describing a characteristic of a sample. C. Statistic because the value is a numerical measurement describing a characteristic of a population. D. Parameter because the value is a numerical measurement describing a characteristic of a population.
Answer: A. Statistic because the value is a numerical measurement describing a characteristic of a sample.
Step-by-step explanation: Statistic are used to describe values obtained from a data sample which are regarded as a subset of the data belonging to an entire population. Therefore, in statistical parlance, numerical measurement obtained from such dataset are called statistic. On the other hand, if data from which a numerical derivation was made is a population which consists of the entire set of observations belonging to a particular group of interest, then the numerical values obtained are referred to as a parameter.
Given: The value [tex]65[/tex]% is a statistic.
The correct option is C (Statistic because the value is a numerical measurement describing a characteristic of a population).
Explanation: We have to determine whether the underlined number is statistics or a parameter.
A sample of employees is selected and it is found that [tex]65[/tex]% own a television.

–4(2x−2)= –(4x−4) what is x?
Answer:
x = 1
Step-by-step explanation:
–4(2x−2)= –(4x−4)
-8x-(-8) = -4x-(-4)
-8x+8 = -4x+4
-8x+8-8 = -4x+4-8
-8x = -4x+(-4)
-8x+4x = -4x+4x+(-4)
-4x = -4
-4x/-4 = -4/-4

Answer:
x=-5 Hope this helped! Goodnight!
Step-by-step explanation:
Let's solve your equation step-by-step.
−3(2x+6)=12
Step 1: Simplify both sides of the equation.
−3(2x+6)=12
(−3)(2x)+(−3)(6)=12(Distribute)
−6x+−18=12
−6x−18=12
Step 2: Add 18 to both sides.
−6x−18+18=12+18
−6x=30
Step 3: Divide both sides by -6.
−6x /−6 = 30 /−6

You have only 1,000$. The price of a TV-set is 1,150$. Can you buy the TV if you get 10% discount?
Answer:
No,I think?
Step-by-step explanation:
Money we have = $1000
Cost of TV set = $1150
10% discount on TV set = $1150 × 10 / 100 (or you can use 10% instead of 10/100)
=$115
Original cost of TV set - 10% of discount on TV set
= $1150 - $115
= $ 1035
since the cost of TV set is greater than the money you have which is (1036 is greater than 1000).You still can't buy the TV set.
