Step-by-step explanation:

3^(2x-1)  = 81    LOG both sides      I had to assume there were parens.

(2x-1) LOG 3 = LOG 81

2x-1 = LOG(81) / (LOG 3) = 4

2x = 5

x = 2.5

Answer:  A  129

Step-by-step explanation:

Because the 2 chords are the same (lines in the circle), the 2 arcs are the same  create an equation that makes them equal

3x+24 = 4x -11             >bring x to one side by subtracting both sides by 3x

24 = x -11                     > add both sides by 11

35 = x

Now that we have solved for x you need to plug that back into the equation for BC

BC= 4x-11

BC = 4(35) - 11

BC =  140 - 11

BC = 129                   >A

In a math class with 19 students, on a day when a test and an assignment were given, there were 10 students who passed the test and 14 students who completed the assignment.

In a math class with 19 students, a test and an assignment were given on the same day.

Out of the 19 students, 10 of them passed the test and 14 students completed the assignment.

This information allows us to analyze the performance and completion rate of the students in the class.

Firstly, we can determine that there are at least 10 students who demonstrated a satisfactory level of understanding and knowledge in the subject matter, as they successfully passed the test.

This indicates that approximately 52.63% (10 out of 19) of the students achieved a passing grade on the test.

Furthermore, we know that 14 students completed the assignment.

This implies that these students fulfilled the requirements and submitted the necessary work within the given timeframe.

Consequently, we can deduce that approximately 73.68% (14 out of 19) of the students in the class completed the assignment.

It's worth noting that there may be overlap between the students who passed the test and those who completed the assignment, as well as students who did both.

However, without additional information, we cannot determine the exact number of students who passed the test, completed the assignment, or did both.

This data provides insight into the performance and diligence of the students in the math class, indicating the proportions of students who met the criteria for passing the test and completing the assignment.

Jonah swam a distance of 29 meters from one corner of the pool to the opposite corner.

To determine how far Jonah swam from one corner of the pool to the opposite corner, we can use the Pythagorean theorem. According to the theorem, in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides.

In this case, the two sides of the right-angled triangle are the length and width of the swimming pool, which are 21 meters and 20 meters respectively. The distance Jonah swam represents the hypotenuse of the triangle.

Using the Pythagorean theorem:

[tex]Hypotenuse^2 = Length^2 + Width^2[/tex]

[tex]Hypotenuse^2[/tex] =[tex]21^2 + 20^2[/tex]

[tex]Hypotenuse^2[/tex]= 441 + 400

[tex]Hypotenuse^2[/tex]= 841

Taking the square root of both sides, we find:

Hypotenuse =[tex]\sqrt{841[/tex]

Hypotenuse = 29

The slope constraint for the zip line is 6 to 8 feet of vertical change for every 100 feet of horizontal change.

So, if the vertical change is 7 feet, the horizontal change must be between 7/6 and 7/8 of a hundred feet, or between 11.67 and 12.5 feet.

For Zip line A, the horizontal distance is 120 feet. So, the vertical change of 7 feet is within the slope constraint.

For Zip line B, the horizontal distance is 140 feet. So, the vertical change of 7 feet is within the slope constraint.

For Zip line C, the horizontal distance is 150 feet. So, the vertical change of 7 feet is within the slope constraint.

Answer:

5.85

Step-by-step explanation:

x ≤ 8 or x > 10 is the solution of the inequality 11 ≥ 2x - 5 or 2x - 5 > 15.

To solve the compound inequality 11 ≥ 2x - 5 or 2x - 5 > 15, we will solve each inequality separately and then combine the solutions.

Solve the first inequality: 11 ≥ 2x - 5

Add 5 to both sides to isolate 2x:

11 + 5 ≥ 2x

16 ≥ 2x

Divide both sides by 2:

8 ≥ x

So the solution to the first inequality is x ≤ 8.

Solve the second inequality: 2x - 5 > 15

Add 5 to both sides to isolate 2x:

2x > 15 + 5

2x > 20

Divide both sides by 2:

x > 10

So the solution to the second inequality is x > 10.

Combining the solutions, we have x ≤ 8 or x > 10.

The value of x that makes [tex]5^x = 625[/tex] true is x = 4.

To determine the value of x in the equation [tex]5^x = 625[/tex], we need to find the exponent that results in 625 when applied to the base 5.

Since 625 can be expressed as 5 raised to the power of 4 ([tex]5^4 = 625[/tex]), the value of x that satisfies the equation is 4.

When we substitute x = 4 into the equation, we get [tex]5^4 = 625[/tex], which is true.

Answer:

The volume is 423.33 cubic millimeters.

Step-by-step explanation:

The formula for volume of a cylinder is given by:

V = πr^2h, where

Step 1:  Find radius, r, of the cylinder:

The diagram shows us the diameter, d, of the circle is 7 mm.  Since the diameter is twice the radius, r, we can find r by dividing the diameter by 2:

r = d / 2

r = 7 / 2

r = 3.5 mm

Thus, the radius of the cylinder is 3.5 mm.

Step 2:  Plug in values and round to the nearest hundredth to find the volume, V, of the cylinder:

Now we can plug in 3.5 for r and 11 for h to find V, the volume of the cylinder.  We can round at the end.

V = π(3.5)^2(11)

V = π(12.25)(11)

V = 134.75π

V = 423.3296101

V = 423.33 mm^2

Thus, the volume of the cylinder is 423.33 cubic millimeters.

To find the area of a trapezoid, you can use the formula:

Area = (1/2) × (base1 + base2) × height

Given that the bases of the trapezoid are 16 feet and 10 feet, and the height is 3 feet, we can substitute these values into the formula:

Area = (1/2) × (16 + 10) × 3

Area = (1/2) × 26 × 3
