The value of expression log₃9 is 2, Option B is correct.

An expression is combination of variables, numbers and operators.

We know that 3 raised to what power equals 9.

We can write this as:

3ˣ = 9

Taking the logarithm of both sides with base 3, we get:

log₃(3ˣ) = log₃ 9

x = log₃9

So, the value of log3 9 is the exponent x that satisfies the equation 3ˣ = 9.

Since 3²= 9, we have:

log₃ 9 = 2

Hence, the value of expression log₃9 is 2.

The value of x is 1.75 and y is 5. The solution is obtained using properties of congruent triangles.

What is a congruent triangle?

Two triangles that are congruent will have precisely the same three sides and three angles.

The dimensions of the triangles' sides and angles determine whether two or more triangles are congruent. A triangle's size is determined by its three sides, and its shape by its three angles. Pairs of corresponding sides and corresponding angles in two triangles are said to be equal if they are congruent. They share a similar size and shape. In triangles, there are numerous congruence conditions.

The triangles are congruent by SAS congruency because

AC = CD (Given)

∠ACB = ∠DCE ( Vertically opposite angles)

BC = CE  (Given)

Thus, Triangle ABC ≅ Triangle DEC

Since, the triangles are congruent, therefore

⇒AC = CD

⇒4y-6 = 2x+6   ...(1)

Also, BC = CE

⇒3y+1 = 4x

⇒(3y+1)/4 = x    ...(2)

Now, substituting the value of x in (1), we get,

⇒4y-6 = 2(3y+1)/4+(6)

⇒4y-6 = (6y+2 +24)/4

⇒16y-24 = 6y+2 +24

⇒10y = 50

⇒y = 5

Now putting the value of y in (2), we get

⇒(3(2)+1)/4 = x

⇒7/4 = x

⇒ x = 1.75

Hence, the value of x is 1.75 and y is 5.

The correct statement regarding the slope and the intercept of the linear function are is given as follows:

The slope is negative two thirds, and the y-intercept is 8. The candle starts at a height of 8 inches and decreases two thirds of an inch every hour.

The two most important features of a linear function are the slope and the intercept, and their meaning is explained as follows:

The input and output variables for this problem are given as follows:

Two points of the function are:

(0, 8) and (3,6).

Given two points, the slope is calculated as the change in y divided by the change in x, hence:

m = (6 - 8)/(3 - 0)

m = -2/3.

Meaning that the candle's height decays at a rate of 2/3 of an inch an hour.

When x = 0, y = 8, hence the intercept of b = 8 represents the initial height of the candle.

The APR (Annual Percentage Rate) is 4.08% while the APY (Annual Percentage Yield) is 4.16%.

The annual percentage yield (APY) is the normal annual percentage rate (APR) based on a compounding period of one year.

The annual percentage rate (APR) represents the cost of borrowing expressed as a percentage.

Thus, while APY considers compound interest, APR does not.

MPR = 0.34%

APR = 4.08% (0.34 x 12)

The formula for computing the APR is as follows:

APY = (1 + APR/N)^N - 1

Where APR is the normal interest rate, N is the number of compounding period in a year.

= (1 + 0.0408/12)^12 - 1

= (1 + 0.0034)^12 - 1

The force F1 can be expressed as a Cartesian vector, F1 = (F1x, F1y). This vector has two components, the x component F1x and the y component F1y. The other forces acting on the gusset plate can be resolved into x and y components using the same method. For example, the force F2 can be resolved into its x and y components, F2x and F2y, to form the vector F2 = (F2x, F2y). The same applies to F3 and F4, which can be expressed as vectors F3 = (F3x, F3y) and F4 = (F4x, F4y), respectively. The x and y components of each force can be found by using trigonometric functions such as sine and cosine, as well as the magnitude of each force.

After evaluating the integral answer is 85/4. thus, option A is the answer.

The given transformation is a change of variables from (x, y) to (u, v). To evaluate the integral using the transformation, we need to use the Jacobian determinant. The Jacobian determinant is the absolute value of the determinant of the matrix of partial derivatives of the transformation.

du/dx = 1, du/dy = 1

dv/dx = -2, dv/dy = 1

The determinant of the matrix of partial derivatives is det(J) = du/dx * dv/dy - du/dy * dv/dx = (1)(1) - (1)(-2) = 3

So the Jacobian determinant is |J| = |3| = 3.

The integral becomes:

R\int \int 5y dx dy = (1/3) R\int \int 5v du dv

where R is the region in the uv-plane that corresponds to the region in the xy-plane bounded by the lines y= -x+1, y=-x+4, y= 2x+2, y= 2x+5

A line which joins the midpoints of two sides of a triangle is Midsegment

A triangle's midsegment is a line formed by joining any two of the triangle's sides at their midpoints. All three sides of a triangle can be divided (split in half) in any triangle, whether it be right, isosceles, or equilateral. The midpoint of each side is the point that is equally spaced from either vertex.

Triangles can have three midsegments because they have three sides. Any two sides can be joined at their midpoints. Half the length of the base is represented by one midsegment (the third side not involved in the creation of the midsegment). That is the only intriguing aspect. It also:

Oracle functions are frequently used to change data from a query result or to conduct computations such calculating the average, sum, or count of a group of numbers.

The delta is the difference between the two x values. To determine the biggest delta such that f(z)-f(1.382)0.0008 when |x-1.382|8, we must first enter x=1.382 into the oracle function and note the result of f. (1.382). Then we must gradually increase x by delta, inserting the new value into the Oracle function and noting the result. Then we may compute f(x)-f(1.382) to determine if it is less than 0.0008.

a) All three pairs of corresponding sides should be equal.

b) Two pairs of corresponding sides and the corresponding angles between them should be equal.

c) Two pairs of corresponding angles and the corresponding sides between them should be equal.

11. In the first diagram, it is given that line segments -

AD = BD

CD = CD (common in both the triangles)

It is given that angles -

∠A ≅ ∠B

This proves that AD ≅ BD and CD = CD.

If ΔACD is congruent with ΔBCD then ∠ADC ≅ ∠BDC.

But not enough information is given about ∠ADC and ∠BDC.

Therefore, ΔACD is not congruent with ΔBCD.

12. In the second diagram, it is given that -

Z is the midpoint of line segment XQ and YP.

This means that line segments -

XZ = ZQ

YZ = ZP

It is also given that ∠XZY = ∠PZQ as they form a pair of vertically opposite angles which are equal.

So, the criteria two pairs of corresponding sides and the corresponding angles between them should be equal is fulfilled.

Therefore, ΔXYZ is congruent with ΔPQZ.

The opposite of a tangent is a cotangent. It is the ratio of a right triangle's adjacent side to its opposite side. It may be expressed mathematically as cot, where is the right triangle's angle. The ratio between the adjacent side and the opposite side will be the cotangent of 30°, for instance, if the right triangle's angle is 30°. When you are aware of the side lengths of a right triangle, the cotangent may be used to determine the angle. For instance, the cotangent of the angle is 0.417, which indicates the angle is around 24°, provided you know the lengths of the near side to be 5 and the opposite side to be 12.

In the given question, the ratio of the adjacent side length to the opposite side length is equal to the cotangent of an angle. The neighboring side length in this example is 9 and the opposite side length is the square root of 57. As a result, the cotangent of angle V is equal to 9 divided by 57 squared.

Step-by-step explanation:

Long division is used to divide polynomials, with the leftover being 0 and the quotient being 26x + 26.

To divide the polynomials, we may utilise long division. To begin, divide the dividend's leading term (522) by the divisor's leading term (2). The leftover is 0 and the quotient is 26.

The quotient (26) is then multiplied by the divisor (2) and subtracted from the dividend (522 13z + 3). This yields the value 522 13z - 52.

The leading term of the new dividend (522) is then divided by the divisor's leading term (2). The leftover is 0 and the quotient is 26.

The quotient (26) is then multiplied by the divisor (2) and subtracted from the new dividend (522 13z - 52). This yields a value of 0.

As a result, the final answer is 26x + 26.

Answer:

2.64

Step-by-step explanation:

Answer: either, because the broken pipe is 2.51 meters long either, because the broken pipe is 2.67 meters long

Step-by-step explanation:

The evaluation of the expression using the order of operations, indicates the operations that come first as follows;

(5 + 5)² + 15 - 10 Parenthesis

40 ÷ 8 · 4  + 2; Division

4 - 2 + 3 · 5; Multiplication

(3² + 8) ÷ 7 - 5; Parenthesis

The order of operations is a rule that serves as a guide for the correct sequence of performing operations in an equation or expression.  

The evaluation expressions can be presented as follows;

First operation;

(5 + 5)² + 15 - 10

The order of operations, PEMDAS, indicates that we get;

1) Parenthesis first

2) Exponents

3) Multiplication and division

4) Addition and subtraction

Based on the above PEMDAS order of operation, the step that should be completed first is the operation within the parenthesis, which is the addition operation (5 + 5)

The correct option is; Parenthesis

Second expression;

40 ÷ 8 · 4 + 2

The operations in the expression are; division, multiplication, and addition

The order of operations indicates that division, which comes first, from the left, should be performed first. The correct option is therefore;

40 ÷ 8 · 4 + 2; division

Third expression;

4 - 2 + 3 · 5

The subtraction is the first operation from the left, but the order of operations, PEMDAS, indicates that the multiplication, 3 · 5 should be performed first, therefore;

Fourth expression;

(3³ + 8) ÷ 7 - 5

The parenthesis which comes first in the order of operations and first among the operations from left to right comes first

Therefore, the parenthesis comes first;
