The reason that will complete the proof is SSS (Side-Side-Side) which states that if three corresponding sides of two triangles are congruent, then the triangles are congruent.
Explanation:Out of the given options, the reason that will complete the proof is SSS which stands for Side-Side-Side. SSS is a congruence postulate that states that if three corresponding sides of two triangles are congruent, then the triangles are congruent.
In this case, since both 'o' and 'sx' are given, we can apply the SSS congruence postulate to show that the triangles are congruent. This is because two sides 'o' and 'sx' are congruent, and the third side of each triangle can be determined by adding up the length of the other sides.
The correct reason that completes the proof is "SAS" which stands for Side-Angle-Side.
SAS is a postulate in geometry that states: "If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent."
To prove two triangles congruent using the SAS postulate, you need to show that two sides of one triangle are congruent to two sides of another triangle, and the included angle (the angle formed by the two sides) of one triangle is congruent to the included angle of the other triangle.
For example, let's say we have two triangles, Triangle ABC and Triangle DEF. To prove them congruent using the SAS postulate, we need to show that AB is congruent to DE, BC is congruent to EF, and the angle at B is congruent to the angle at E.
Once we have established these congruencies, we can conclude that Triangle ABC is congruent to Triangle DEF.
Therefore, in the context of the given question, the reason that completes the proof is SAS.

If x=-3/2:
y=(2x-1)(2x-3)(2x+5)

m<2=m<7= alternate exterior
m<1=m<4= vertical
m<5=m<8= vertical
m<2=m<3= vertical
m<6=m<7= vertical
Answer:
Vertical angles : Opposite angles made by two intersecting lines.
Corresponding angles : which occupy the same relative position at each intersection where a straight line crosses two others.
Alternate interior angles : when a transversal passes through two line then the angles that are formed on opposite sides of the transversal and inside the two lines.
Alternate exterior angles : angles on the outer side of each of those two lines but on opposite sides of the transversal.
Here, line k passes through the lines p and q,
Thus, by the above explanation,
Vertical pairs are, angle 1 and angle 4, angle 2 and 3, angle 5 and angle 8, angle 6 and 7,
Corresponding pairs,
angle 2 and angle 6, angle 1 and angle 5, angle 4 and angle 8, angle 3 and angle 7,
Alternate interior angles pair,
angle 4 and angle 5, angle 6 and angle 3,
Alternate exterior angles pair,
angle 2 and angle 8, angle 1 and angle 7,
Vertical angles are always equal in measure,
Now, the p and q are parallel lines,
So, the corresponding angles will be congruent as well as alternative interior or exterior will be congruent.
Therefore, the required pair,
Corresponding pairs :
m∠1=m∠5
m∠2=m∠6
Alternative interior pairs :
m∠3=m∠6
m∠4=m∠5,
Alternate exterior pairs :
m∠1=m∠8
m∠2=m∠7
Vertical pairs :
m∠1=m∠4
m∠5=m∠8
m∠2=m∠3

Myron put $5000 in a 2-year CD paying 3% interest, compounded monthly. After 2 years, he withdrew all his money. What was the amount of the withdrawal?
Answers
Answer:
$5308.79
Step-by-step explanation:
The future value can be computed from ...
FV = P(1 +r/n)^(nt)
where P is the principal invested, r is the annual interest rate, n is the number of times per year it is compounded, and t is the number of years.
You have P = $5000, r = 0.03, n = 12 (months per year), t = 2.
Filling in the given numbers, we have ...
FV = $5000(1 +.03/12)^(12·2) ≈ $5000(1.0617570) ≈ $5308.79
The amount of the withdrawal will be $5308.79.
Final answer:
To find the withdrawal amount for Myron's CD, the compound interest formula is used with the respective values plugged in. After 2 years, with 3% interest compounded monthly on a principal of $5000, the withdrawal amount is approximately $5,304.91.
Explanation:
The question deals with the calculation of compound interest for a Certificate of Deposit (CD), specifically with different compounding periods.
To calculate the withdrawal amount for Myron's 2-year CD with a principal amount of $5000 at a 3% interest rate compounded monthly, the formula for compound interest is:
[tex]A = P (1 + r/n)^{nt[/tex]
Where:
A = the amount of money accumulated after n years, including interest.P = the principal amount (initial deposit).r = the annual interest rate (decimal).n = the number of times that interest is compounded per year.t = the time the money is invested for in years.By plugging in Myron's values, we get:
[tex]A = $5000 (1 + 0.03/12)^{12\times 2[/tex]
Calculating this we find that A, the withdrawal amount, is approximately $5,304.91.

The rule which describes the translation of the figure is T–3, –2(x, y).
The translation T(x, y) → (x – h, y – k) moves a point (x, y) to a new point (x – h, y – k).
T–3, –2(x, y) moves the point 3 units to the right and 2 units down.
T–3, 2(x, y) moves the point 3 units to the right and 2 units up.
T3, –2(x, y) moves the point 3 units to the left and 2 units down.
T3, 2(x, y) moves the point 3 units to the left and 2 units up.
So the answer is T–3, –2(x, y).

given the conversion factor 3.28 ft/ 1m which cube above has the larger surface area

Answers
We have then:

Cube B:

The surface area of a cube is:
A = 6 * L ^ 2
Where,
L: side
Since cube A has a longer side (2.13m) then it will have the largest surface area.
Answer:
Cube A has the larger surface area
Final answer:
After converting Cube B's side length to feet, Cube A has a surface area of 294 ft² while Cube B has a surface area of 258.2016 ft², making Cube A the one with the larger surface area.
Explanation:
To determine which cube has the larger surface area, we must work with a common unit of measurement for both cubes. We'll convert Cube B from meters to feet using the conversion factor 3.28 ft/1m.
For Cube A with a side length of 7 feet, the surface area (SA) is calculated by the formula SA = 6 × s² (where 's' is the side length).
SA (Cube A) = 6 × (7 ft)² = 6 × 49 ft² = 294 ft².
For Cube B with a side length of 2 meters, we first convert meters to feet: 2 m × 3.28 ft/m = 6.56 ft. So, the surface area of Cube B becomes:
SA (Cube B) = 6 × (6.56 ft)² = 6 × 43.0336 ft² = 258.2016 ft².
Between Cube A and Cube B, Cube A has the larger surface area.

What is Quadratic equation?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax² + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term. First, there must be a term other than zero in the coefficient of x²(a>0) for an equation to be a quadratic equation. The x² term is written first when constructing a quadratic equation in standard form, then the x term, and finally the constant term. The numerical values of a, b, and c are often expressed as integral values rather than fractions or decimals.
Given Equation:
h(t) = –16t² + 14t
For the Hangout time we can consider the function h(t)=0
