Answer:

25%

Step-by-step explanation: Because a 25 % increase is calculated by multiplying by 1.25.

Expressing as single logarithm 3/2㏑4x⁶ - 2/5㏑2y²⁵ = ㏑(2x⁹/y¹⁰)

Since we have the logarithm expression

3/2㏑4x⁶ - 2/5㏑2y²⁵

To simplify, we proceed as follows

First, we use the power law of logarithm which states that

n㏑x = ㏑xⁿ

So, using this, we have that

3/2㏑4x⁶ - 2/5㏑2y²⁵ = ㏑4x⁶ - 2/5㏑2y²⁵

[tex]= ln4x^{6\times\frac{3}{2} } - ln2y^{25\times\frac{2}{5} } = ln4x^{3\times3} } - ln2y^{5\times2 }[/tex]

= ㏑4x⁹ - ln2y¹⁰

Using the subtraction law of logarithm, which states that

㏑a - ㏑b = ㏑(a/b), we have that

㏑4x⁹ - ln2y¹⁰ =  ㏑(4x⁹/2y¹⁰)

= ㏑(2x⁹/y¹⁰)

So, 3/2㏑4x⁶ - 2/5㏑2y²⁵ = ㏑(2x⁹/y¹⁰)

The complete table for the time it takes to empty the barrel for the given rates is attached below. The value of constant k is 60.

To solve the problem, we can use the formula for inverse variation

time = k/leaking rate

where k is a constant of proportionality. We can find k by using the information given in the problem

30 = k/2

Solving for k, we get:

k = 60

Now we can use this value of k to fill in the table

Leaking rate (gallons per minute)                Time to empty (minutes)

      2                                                                           30

Your question is incomplete but most probably your full question was,

The solution of the differential equation is y + e²ˣ = Ceˣ, if Ceˣ > 0

or -y - e²ˣ = Ceˣ, if Ceˣ < 0.

The solution of the differential equation is calculated as follows;

dy/dx = e²ˣ + y

Apply the method of separating viables;

dy/dx = e²ˣ + y

dy/(y + e²ˣ) = dx

Integrate both sides;

∫ dy/(y + e²ˣ) = ∫ dx

ln|y + e²ˣ| = x + C

To solve for y, we need to exponentiate both sides;

|y + e²ˣ| = e^(x+C) = Ceˣ

The final solution becomes;

y + e²ˣ = Ceˣ, if Ceˣ > 0

We can solve this inequality for x as follows:

3 - 3x ≤ 4x + 7

Subtract 4x from both sides:

3 - 7x ≤ 7

Subtract 3 from both sides:

-7x ≤ 4

Divide both sides by -7, remembering to reverse the inequality since we are dividing by a negative number:

x ≥ -4/7

Therefore, the solution to the inequality is:

x ≥ -4/7

The combinations of side lengths that would not form a triangle with vertices X, Y, and Z is A. XY = 15 mm, YZ = 10 mm, and XZ = 28 mm.

We shall us the triangle inequality theory for this problem.

According to this theory, the addition of the lengths of any two sides of a triangle must be greater than the length of the third side.

Therefore, for the sides XY, YZ, and XZ to form a triangle, we must have:

XY + YZ > XZ

YZ + XZ > XY

XZ + XY > YZ

We can check each option to see if it satisfies these conditions:

A. XY = 15 mm, YZ = 10 mm, XZ = 28 mm

15 + 10 > 28 (not satisfied)

10 + 28 > 15 (satisfied)

28 + 15 > 10 (satisfied)

Option A does not satisfy the condition XY + YZ > XZ, so it would not form a triangle.

B. XY = 18 mm, YZ = 10 mm, XZ = 25 mm

18 + 10 > 25 (satisfied)

10 + 25 > 18 (satisfied)

25 + 18 > 10 (satisfied)

Option B satisfies all the conditions, so it would form a triangle.

C. XY = 18 mm, YZ = 13 mm, XZ = 22 mm

18 + 13 > 22 (satisfied)

13 + 22 > 18 (satisfied)

22 + 18 > 13 (satisfied)

Option C satisfies all the conditions, so it would form a triangle.

D. XY = 15 mm, YZ = 10 mm, XZ = 22 mm

15 + 10 > 22 (satisfied)

10 + 22 > 15 (satisfied)

22 + 15 > 10 (satisfied)

Option D satisfies all the conditions, so it can form a triangle.

Therefore, the combinations that would not form a triangle is A, where XY = 15 mm, YZ = 10 mm, and XZ = 28 mm.

The measure of an inscribed angle in a circle equals half the measure of its intercepted arc.

3) 56 + 2x = (1/2)(112 + x)

x = 0, so the measure of arc BCD is

360° - 112° = 248°.

5) 3 + 20x = (1/2)(43x - 3)

6 + 40x = 43x - 3

3x = 9, so x = 3

The measure of arc MLK is

360° - (43(3) - 3)° = 360° - 126° = 234°.

Elaborate ur question about - 34

Answer: The slope of the ramp is defined as the rise over the run, where the rise is the height of the step (2 feet) and the run is the horizontal distance from the bottom of the ramp to the step (7.0 feet). However, since the ramp is not straight but inclined, we need to use the length of the ramp (7.3 feet) to calculate the actual horizontal distance it covers.

Therefore, the run of the ramp is the square root of the difference between the length of the ramp squared and the height of the step squared:

run = sqrt(7.3^2 - 2^2) = sqrt(52.29 - 4) = sqrt(48.29) ≈ 6.95 feet

Now we can calculate the slope of the ramp:

slope = rise / run = 2 / 6.95 = 0.2885 ≈ 2/7

Therefore, the slope of the ramp is approximately 2/7.

The volume of the prism in cubic inches is 4/9 cubic in if each cube in the prism measures 1/3 inch on one side.

Hence, the correct option is A.

If each cube in the prism measures 1/3 inch on one side, then the volume of one cube is (1/3)³ = 1/27 cubic inches.

To find the volume of the prism, we need to know how many cubes are in the prism. Let's assume the prism has dimensions of length L, width W, and height H, all measured in units of cubes. Then, the total number of cubes in the prism is L × W × H.

Therefore, the volume of the prism in cubic inches is

Volume = (L × W × H) × (1/27) cubic inches

From the given figure, we can find

L = 3 inch

W = 2 inch

H = 2 inch

Substitute the values in formula to find the volume

= (3 × 2 × 2) × (1/27) cubic inches

= 4/9 cubic inches

Hence, the correct option is A.

Step-by-step explanation:

First, let’s find the area of the entire circle. The area for a circle is 3.14 * radius^2

3.14*18^2 = 1017.36

Now, notice how the angle marked is 90 degrees, that means that this section of the circle is 90/360 (360 is the angle of a circle), or 1/4 of a whole circle. Now we can multiply 1/4 by the area to find 1/4 of the whole circle.

1017.36*1/4 = 254.34

The initial sum of the number of students in College P and College Q is 5040.

We have,

Let's assume that the number of students in college Q is represented by Q, and the number of students in college P is represented by P:

P = Q - 0.32Q = 0.68Q

We also know that if 960 more students enroll in college P, the two colleges will have the same number of students.

So, we can set up another equation:

P + 960 = Q

We can substitute the first equation into the second equation to eliminate P:

0.68Q + 960 = Q

Solving for Q, we get:

0.32Q = 960

Q = 3000

The initial number of students in college Q was 3000.

We can use this value to find the initial number of students in college P:

P = 0.68Q = 0.68(3000) = 2040

So, the initial sum of the number of students in College P and College Q is:

P + Q = 2040 + 3000 = 5040

Since the equation of this line passes through the origin (0, 0) and parallel to the line 4x - 5y = 10, the slope is given by;

Slope, m = 4/5

y - y₁ = m(x - x₁)

y - 0 = 4/5(x - 0)
