the first one is part of the question not an answer iption

Step-by-step explanation:

[tex] \because \triangle \: RSU \sim \: \triangle VST \\ \\ \therefore \: \frac{RS}{VS} = \frac{7}{14} = \frac{1}{2} ....(1) \\ \\ \angle RSU \cong \: \angle VST ....(2) \\ (vertically \: opposite \: angles) \\ \\ \frac{US}{TS} = \frac{4}{8} = \frac{1}{2} ....(3) \\ \\ from \: equations \: (1) \: (2) \: and \: (3) \\ it \: is \: clear \: that: \\ \triangle \: RSU \sim \: \triangle VST\\ ..(by \:SAS\:similarity\:postulate) [/tex]

Thus, given triangles are similar by SAS similarity postulate.

When the triangles RSU and VST are said to be similar, it means the corresponding sides and angles are proportional and equal respectively, which is known as the Angle-Angle criterion for similarity.

If the triangles RSU and VST are similar (RSU ~ VST), it means the corresponding sides and angles of the two triangles are proportional, and the corresponding angles are equal. This is also known as the Angle-Angle (AA) criterion for similarity. The order of the letters signifies the corresponding parts of the triangles. R corresponds to V, S to S, and U to T. So, the angles R and V are congruent, as are the angles U and T. Because we have two pairs of congruent angles, we can say that the triangles are similar by the AA criterion.

Answer:

C)

Step-by-step explanation:

By using mental math and breaking down the numbers into parts, you find that 2,100 more people attended the baseball game on Thursday than on Friday.

The subject of this problem is subtraction. To find out how many more people attended the baseball game on Thursday than on Friday, you need to subtract the number of people who attended on Friday from the number who attended on Thursday. In math terms, this would be 13,450 (Thursday's attendance) - 11,350 (Friday's attendance).

To make this easier using mental math, you might notice that both numbers end in 50. You could subtract these separately: 13,000 - 11,000 = 2,000 and 450 - 350 = 100. Adding these results together, you get 2,000 + 100 = 2,100.

So, the answer is that 2,100 more people attended the baseball game on Thursday than on Friday.

Step-by-step explanation:

To solve the given system of linear equations, we use the elimination method to find the solution, which is (x, y) = (-1, 1).

The student is asking how to find the solution to a system of linear equations:

x + 5y = 4

3x - 7y = -10

To solve this system, one can use the method of elimination.

Multiply the first equation by 3 and the second equation by 1 to align the coefficients of x.

The resulting equations are:

3x + 15y = 12

3x - 7y = -10

Subtract the second equation from the first to eliminate x:

22y = 22

Divide by 22 to find y:

y = 1

Substitute y = 1 into the original first equation:

x + 5(1) = 4

Solve for x:

x = -1

The solution to the system is (x, y) = (-1, 1).

Answer:

The slope of y=4-2x is -2.

Answer:

B. of the AAS congruence theorem.

Step-by-step explanation:

Triangles TSR and QRS share side SR

SR=RS

Angle TSR and Angle QRS are right angles, so

∠S= ∠R

Angle T Is-congruent-to Angle Q, so

∠T= ∠Q

From these data, we have one congruent side and two congruent angles. The possible congruence theorem that we can apply will be either ASA or AAS. In the ASA theorem, the congruence side must be between the two congruent angles.

The congruence side required for the ASA theorem for this triangle is ST = RQ. It is wrong because the congruent side we have is SR=RS. The correct option is the AAS theorem.

Answer:

A, B, and C are true

Step-by-step explanation:

Using the Factor Theorem to find the function, the correct statement is:

The function is positive on (0,∞).

The Factor Theorem states that a polynomial function with roots

x1, x2,...xn  is given by:

f(x) = a(x-x1)(x-x2).....(x-xn)

In which a is the leading coefficient.

here, we have,

The described roots means that:

x1 = 0, x2 = x3= x4 =x5 = 2

Hence the function is:

f(x) = x(x - 2)^4

(x - 2)^4 is always positive, hence the sign depends on the sign of x, which means that the correct statement is:

The function is positive on (0,∞).

Answer:

  [tex]0.\overline{1}[/tex]

Step-by-step explanation:

The fraction reduces to 1/9. Since you're familiar with the decimal equivalents of fractions with denominators less than 10, you know this has the decimal equivalent:

  1/9 = 0.11111111...(repeating)

_____

Even if you're not familiar with the equivalent of 1/9, you probably know that ...

  1/3 = 0.33333...(repeating)

and

  2/3 = 0.66666...(repeating)

Of course, 1/3 = 3/9, so dividing 0.333... by 3, we get 1/9 = 0.111....

_____

The attachment shows the long division. It gets boring quickly.

Final answer:

The equivalent decimal of the fraction 5/45 is approximately 0.1111

Explanation:

To find the equivalent decimal of the fraction 5/45, we can start by simplifying the fraction. Since both the numerator (5) and the denominator (45) are divisible by 5, we can reduce the fraction to 1/9.

To convert this simplified fraction into a decimal, we divide 1 by 9.

1 ÷ 9 = 0.111...

The decimal 0.111... means that the 1 repeats indefinitely, which is known as a repeating decimal.

If we want to convert this repeating decimal into an approximation with a specific number of decimal places, we could round it. For example, we could say 0.111... is approximately 0.111 when rounded to three decimal places.

Answer:

4(x-1)units

Step-by-step explanation:

In a given rectangle, the length of the rectangle is the shorter side while its breadth is the longer side.

Since we have 2 lengths and 2 breadths in a rectangle, the perimeter of the rectangle will be 2L+2x where

L is the length(shorter side) and x is the breadth (longer side).

According to the question, the shorter side(L) is 2 units less than the longer side(x). Mathematically,

L = x-2

Substituting L = x-2 into the formula of perimeter of a rectangle we have,

P = 2(x-2) + 2x

P = 2x-4+2x

P = 4x-4

P = 4(x-1)

The perimeter of the rectangle will be 4(x-1)units

Answer:

The function is [tex]f(x) = 4(\sqrt[3]{16} )^{2x}[/tex].

Step-by-step explanation:

We have to choose from options the exponential function which has a simplified base of 4∛4 i.e. ∛(256).

Now, the exponential function in the option III will be the answer.

The function is [tex]f(x) = 4(\sqrt[3]{16} )^{2x}[/tex].

So, the base is [tex](\sqrt[3]{16} )^{2}[/tex] = [tex]\sqrt[3]{16^{2}} = \sqrt[3]{256} = 4\sqrt[3]{4}[/tex]. (Answer)

The general formula of an exponential function is [tex]f(x) = a(b)^{x}[/tex] , where b is called the base of the function.  

The function that has a simplified base of (4∛4) is;

Option C; 4(∛16)^(2x)

From the general formula of an exponential function, we know that;

f(x) = a(b)^(x)

Now, we have;

f(x) = (4∛4)^(x)

Thus, looking at the options, option C is correct because;

In 4(∛16)^(2x), the base is (∛16)² and when we simplify it, we will get 4³(√4) because;

(∛16)² = √(16^(⅔))

>> 256^(⅓)

>> 4∛4

This is the same as our initial value.

Answer:A ($139.26)

Step-by-step explanation:

y=a.(X-x1)(X-x2)

x1 and x2 are x-intercepts

x1=-3

x2=1

other points: (-1,8) and (0,5)

y=a.(x+3).(x-1)

a=-2

f(x)= -2.(x+3)(x-1)

The equation is [tex]\[f(x) = -2 \cdot (x + 3)(x - 1)\][/tex]

Given the quadratic equation in the form \(y =[tex]a \cdot (X - x_1)(X - x_2)\), where \(x_1\) and \(x_2\)[/tex]represent the x-intercepts, and the given x-intercepts are[tex]\(x_1 = -3\) and \(x_2 = 1\).[/tex]

Using the given x-intercepts [tex]\(x_1 = -3\) and \(x_2 = 1\)[/tex], the equation becomes [tex]\(y = a \cdot (x + 3)(x - 1)\).[/tex]

We are also provided with two other points: (-1, 8) and (0, 5).

We can substitute the point (-1, 8) into the equation to solve for \(a\):

[tex]When \(x = -1\) and \(y = 8\):\[8 = a \cdot ((-1) + 3)((-1) - 1)\]\[8 = a \cdot (2)(-2)\]\[8 = -4a\]\[a = -2\][/tex]

Therefore, the value of \(a\) is -2.

Substituting [tex]\(a = -2\) into the equation \(y = a \cdot (x + 3)(x - 1)\), we get:\[y = -2 \cdot (x + 3)(x - 1)\][/tex]

Answer:

Step-by-step explanation:

15 = 7 - /2x/

Subtract 7 from both sides ( if it was negative you would add it)

(15-7) = (7 - 7) -/2x/ now the seven is no longer there

8 = -/2x/

Now divide 2 from both sides

( 8 / 2 ) = - /(2 / 2)x/

4 = -/x/

4 = -x

Now the two is no longer there but the x would still be there because you divided it by 2 and not 2x

To solve the equation 15 = 7 - |2x|, consider two cases: 2x ≥ 0 and 2x < 0. In case 1, x = -4. In case 2, x = 4.

To solve the equation 15 = 7 - |2x|, we need to eliminate the absolute value. To do this, we can consider two cases: when 2x is positive and when 2x is negative.

Case 1: 2x ≥ 0

In this case, the equation becomes 15 = 7 - 2x, which simplifies to 2x = -8. Solving for x, we get x = -4.

Case 2: 2x < 0

In this case, the equation becomes 15 = 7 + 2x, which simplifies to 2x = 8. Solving for x, we get x = 4.

Therefore, the solution to the equation 15 = 7 - |2x| is x = -4 or x = 4.
