What is congruent triangles?

If and only if we can use rigid transformations to map one figure onto the other, then two figures are said to be congruent. All corresponding sides and angles are congruent because rigid transformations maintain distance and angle measure. Therefore, measuring all of the sides and angles of a pair of triangles would be one method of determining whether they are congruent.

Let the given two triangles, ΔABC and ΔDEF are congruent.

We have to find the congruent pairs from the given two congruent triangles.

First to find the congruent pairs for angles.

The correct reason for Step 2 is the Vertical Angle Theorem

There are four angles created when two straight lines cross or intersect at a point, in which two sets of angles are not contiguous. These pair of non-adjacent angles are known as Vertical angles or Vertically opposite angles.

According to The theorem of vertical angles, two opposing vertical angles that are created when two straight lines intersect at a point, are always equal to one another.    

Here we have

3 three straight lines named SZ, TV, WY  

Where Line SZ and TV intersected at U,

Thus the formed pairs of Vertical angles are ∠SUV, ∠TUX;  ∠SUT, ∠VUX

As we know according to Vertical Angles Theorem the vertical angles are equal

=> ∠SUV = ∠TUX

Answer: Neither

Step-by-step explanation:

The answer to the given problem can be stated as, "$ 500 interest will be earned in approximately 0.14 years."

The compound interest is a form of interest where the rate of interest is applied on the amount obtained after every interval of time.

The formula to calculate the amount is as follows,

A = P(1 + r)^(nt)

The, the interest is given as  P[(1 + r)^(nt) - 1]

Substitute all the corresponding values in the above expression to obtain,

500 = 1700[(1 + 2/100)^(nt) - 1]

=> 500 + 1700 =  1700(1 + 2/100)^(nt)

=> (1 + 2/100)^(nt)  = 2200/1700

=> 1.02^(nt) = 22/17

Since, there are 4 quarters in one year, n = 4.

1.02^(4t) = 1.294

=> 4t = log(1.294) ÷ log(1.02)

=> 4t = 0.562

=> t = 0.14

Hence, it will take 0.14 years to earn the interest of $500.

The results of operations between the two functions f(x) = 2 · x + 1 and g(x) = 6 - x are listed below:

In this problem we have the definitions of two functions, linear equations on both cases. The procedure consists in using the definitions of operations between two functions and evaluate the resulting expression at a given value of x:

Addition

(f + g)(x) = f(x) + g(x)

Subtraction

(f - g)(x) = f(x) - g(x)

Multiplication

(f · g)(x) = f(x) · g(x)

Division

(f / g)(x) = f(x) / g(x)

Now we proceed to derive each expression and evaluate the resulting expression:

(f + g)(x) = (2 · x + 1) + (6 - x)

(f + g)(x) = x + 7

(f + g)(2) = 2 + 7

(f + g)(2) = 9

(f - g)(x) = (2 · x + 1) - (6 - x)

(f - g)(x) = 3 · x - 5

(f - g)(- 5) = 3 · (- 5) - 5

(f - g)(- 5) = - 20

(g - f)(x) = (6 - x) - (2 · x + 1)

(g - f)(x) = - 3 · x + 5

(g - f)(4) = - 3 · 4 + 5

(g - f)(4) = - 7

(f · g) (x) = (2 · x + 1) · (6 - x)

(f · g) (x) = 2 · x · (6 - x)  + 6 - x

(f · g) (x) = 12 · x - 2 · x² + 6 - x

(f · g) (x) = - 2 · x² + 11 · x + 6

(f · g)(1 / 2) = - 2 · (1 / 2)² + 11 · (1 / 2) + 6

(f · g)(1 / 2) = 11

(f / g) (x) = (2 · x + 1) / (6 - x)

(f / g)(- 1) = [2 · (- 1) + 1] / [6 - (- 1)]

(f / g)(- 1) = - 1 / 7

(a) Ann's monthly payment: $133.33

(b) Ann's total amount to repay the loan:$8000

(c) The total amount of interest Ann will pay:-$12000

What is amortized loan?

A loan that has planned, monthly payments that are applied to both the principle and interest accrued is known as an amortized loan.

To solve this problem, we need to use the following formula for an amortized loan:

[tex]Monthly\ payment = (Interest rate / 12) * Loan\ amount / (1 - (1 + (Interest \ rate / 12))^(-Term * 12))[/tex]

(a) Find Ann's monthly payment:

Substituting the given values into the formula, we get:

[tex]Monthly\ payment = (0.08 / 12) * 20000 / (1 - (1 + (0.08 / 12))^(-5 * 12))\\\\Monthly\ payment = 133.33[/tex]

Therefore, Ann's monthly payment is $133.33.

(b) Find Ann's total amount to repay the loan:

The total amount to repay the loan is equal to the sum of the monthly payments over the term of the loan. Since Ann's monthly payment is $133.33 and the term of the loan is 5 years, the total amount to repay the loan is equal to $133.33 * 5 * 12 = $8000.

(c) Find the total amount of interest Ann will pay:

The total amount of interest Ann will pay is equal to the total amount to repay the loan minus the loan amount. Since Ann's total amount to repay the loan is $8000 and the loan amount is $20000, the total amount of interest Ann will pay is equal to $8000 - $20000 = -$12000.

Note that the total amount of interest Ann will pay is a negative number because the loan amount is greater than the total amount to repay the loan. This means that Ann will end up paying less than the loan amount due to the amortization of the loan.

The probability that there will be no drowning this year is 0%

and  the probability that there will be at least 6 accidents this year is 0.003%

What is the probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

We have,

3 per year for every 100000 of tourists

if in a year 200000 tourists visited this resort,

Probability formula:

P(A) = f / N

P(A) = Probability of an event (event A) occurring.

f = Number of ways an event can occur (frequency)

N = Total number of outcomes possible.

so f = 3,

N = 100000

P(A) = f / N = 3/100000 = 0.00003 = 0.003%

so, the probability of the previous year is 0.003%.

0.003% = f / 200000

f = 200000 * 0.003% = 6

a) The probability that there will be no drowning this year:

P(A) = 0 / 200000 = 0

b) The probability that there will be at least 6 accidents this year:

P(A)  = 6 / 200000

P(A) = 0.003%

Hence, the probability that there will be no drowning this year is 0%

Step 2 of 2 : Solve the equation for the unknown quantity.

The volume of a box with dimensions a, b, and c is given by

V(a,b,c)=abc.

It follows that

dV(a,b,c)/V(a,b,c)=da/a + db/b + dc/c .

Therefore, "in first approximation", the relative error in volume is the sum of the relative errors in the side lengths.

In the given example the relative errors in the side lengths are 1%. As the case may be these add up, and we obtain a relative volume error of 3% or 1.5 cubic inches as a "first estimate".

The actual minimal volume of the box under the given constraints is

4.95*4.95*1.98=48.51495 cubic inches, which is <1.5 cubic inches off; and the maximal volume is 5.05*5.05*2.02=51.51505 cubic inches, which is 1.51505>1.5 off the intended value of 50 cubic inches. It follows that the worst-case analysis gives a larger error than the "first estimate".

Takeuru made 18 souffles with the 72 eggs he purchased.

A ratio in mathematics demonstrates how many times one number is contained in another. For instance, the ratio of oranges to lemons in a dish of fruit is eight to six if there are eight oranges and six lemons (that is, 8:6, which is equivalent to the ratio 4:3). Similarly, the ratio of oranges to the total amount of fruit is 8:14, while the ratio of lemons to oranges is 6:8 (or 3:4). (or 4:7).

The quantities in a ratio can be of any kind, such as counts of people or things, measures of lengths, weights, or times, etc. Both numbers must be positive in the majority of situations.

Let e = the quantity of eggs Takeuru purchased.

Takeuru purchased s souffles total.

Then, as Takeuru purchased 4 times as many eggs as he used to make soufflés, e=4s.

Since Takeuru uses 3 eggs for each souffle he bakes and has 18 eggs remaining after backing, the equation is: e-3s=18.

This states that after Takeuru utilized three eggs for each souffle, there are still 18 eggs available.

There are now two equations:

e=4s

e-3s=18

When we solve for s using equation (2) and the value of e from equation (1), we get the following results: s=18

e=4s

e=4×18

e=72

Therefore, Takeuru purchased 72 eggs.

There were 18 soufflés that Takeuru purchased.

When businesses in a cutthroat sector start making money, it opens the door for more businesses to enter the market, which leads to a shift to the right in the supply curve, a drop in price, and the return of all businesses to a state of no economic profit.

If the market price is lower than the average total cost, a company will experience positive economic profit in the short term.
