The initial volume of the solution in container Q is 1.6 liters.

Let's first discover how a lot solution was poured from container Q into container P:

0.4 x volume of solution in container Q = 0.4Q

the total volume of solution in container P after this transfer is:

800 ml + 0.4Q ml

Subsequent, 3/8 of this overall volume in container P is poured into container R:

(3/eight) x (800 ml + 0.4Q ml) = 300 ml + 0.15Q ml

We recognise that field R includes 540 ml of solution now, so we are able to set up an equation:

300 ml + 0.15Q ml = 540 ml

Solving for Q, we get:

0.15Q ml = 240 ml

Q = 1600 ml

Consequently, the initial volume of the solution in container Q is 1.6 liters.

The value of y is 116°.

Three given Adjacent angles are 28°, 36° and y°.

When two angles are adjacent, they have a common side between them and share a common vertex where the two sides meet. The angles are said to be adjacent because they are next to each other.

We know that if a ray stands on a straight line, then the sum of adjacent angles is 180°.

So, 28° + y° + 36° = 180°

y° + 64° = 180°

Subtracting 64° from both sides.

y°- 64° = 180° - 64°

y° = 116°

Hence, the value of y is 116°.

1. The area of square C is 625 ft². 2. The perimeter of square C is 46 ft. 3. The area of square B is 1456 ft². 4. The length of square A is 4√15 ft.

A key idea in geometry that connects the lengths of a right triangle's sides is known as the Pythagorean Theorem. It says that the hypotenuse's square length, which is the side that faces the right angle, is equal to the sum of the squares of the lengths of the other two sides in a right triangle. It has the following mathematical expression:

a² + b² = c²

1. The area of square C can be found using the Pythagorean Theorem:

a² + b² = c²

Using the area the side is calculates as follows:

Side length of A = √225 = 15 ft

Side length of B = √400 = 20 ft

Now,

15² + 20² = c²

225 + 400 = c²

625 = c²

c = √625 = 25 ft

So the area of square C is:

Area of C = 25² = 625 ft²

2. The perimeter of square C can be found by adding up the side lengths of all three squares:

Perimeter of A = 36 ft, so each side length of A is 9 ft.

Perimeter of B = 48 ft, so each side length of B is 12 ft.

Perimeter of C = Side length of A + Side length of B + Side length of C

Perimeter of C = 9 + 12 + c

We found earlier that c = 25 ft, so we can substitute that in:

Perimeter of C = 9 + 12 + 25 = 46 ft

3. The area of square B can be found using the fact that the areas of squares A, B, and C are related by the equation:

Area of A + Area of B = Area of C

We know the area of A and the area of C, so we can solve for the area of B:

Area of A = 15² = 225 ft²

Area of C = 1681 ft²

Area of A + Area of B = Area of C

225 + Area of B = 1681

Area of B = 1456 ft²

4. Perimeter of B = 64 ft

Side length of B = 64 / 4 = 16 ft

Now we can use the Pythagorean Theorem to find the side length of C:

a² + b² = c²

a = 15 ft (side length of A)

b = 16 ft (side length of B)

c = √(a² + b²) = √(15² + 16²) = √481 = 22 ft

Finally, we can use the Pythagorean Theorem again to find the side length of A:

a² + b² = c²

b = 16 ft (side length of B)

c = 22 ft (side length of C)

a = √(c² - b²) = √(22² - 16²) = √240 = 4√15 ft

For the function f(x) = x^2e^7x the critical numbers are 0 and -2/7 and using the First Derivative Test local minima at x = 0 and -2/7.

The function f(x) = x²e⁷ˣ

Differentiate the function f(x) with respect to x

f'(x) = 2xe⁷ˣ + 7x²e⁷ˣ

f'(x) = xe⁷ˣ(2 + 7x)

Now put f'(x) = 0 for critical points.

xe⁷ˣ(2 + 7x) = 0

x = 0                 2 + 7x = 0              e⁷ˣ ≠ 0

x = 0                 x = -2/7                e⁷ˣ ≠ 0

Hence, 0 and -2/7 are the critical points.

f'(x) = 2xe⁷ˣ + 14x²e⁷ˣ

Now f''(x) = 2e⁷ˣ + 14xe⁷ˣ + 28xe⁷ˣ + 98x²e⁷ˣ

f''(x) = 2e⁷ˣ + 42xe⁷ˣ + 98x²e⁷ˣ

f''(x) = 2e⁷ˣ(1 + 21x + 49x²)

Now f''(x) at x = 0

f''(0) = 2e⁷⁽⁰⁾(1 + 21(0) + 49(0)²)

f''(0) = 2(1 + 0 + 0)

f''(0) = 2 > 0

So f(x) has minima at x = 0

Local minima at x = 0 and y = 0.

Now f''(x) at x = -2/7

f''(0) = 2e⁻²(1 + 21(-2/7) + 49(-2/7)²)

f''(0) = 2e⁻²(1 - 6 + 4)

f''(0) = -2e⁻² < 0

f(x) has local minima at x = -2/7

Now y at x = -2/7 is

y = f(-2/7)

y = (-2/7)² e⁻²

2. Yes, battery life is a function of time. The longer a battery is in use, the more its charge will deplete. However, it is not necessarily a linear function as the rate of battery drain can vary depending on factors such as usage patterns, app activity, and temperature. In this specific case, it appears that the rate of battery drain may be slowing down as the percentage decrease from 90% to noon is less than the decrease from fully charged to 90%.

In calculus and related areas, a linear function is a function whose graph is a straight line, that is, a polynomial function of degree zero or one. For distinguishing such a linear function from the other concept, the term affine function is often used. A linear function from the real numbers to the real numbers is a function whose graph (in Cartesian coordinates) is a non-vertical line in the plane. The characteristic property of linear functions is that when the input variable is changed, the change in the output is proportional to the change in the input.

Step-by-step explanation:

Basically, you will find the circumference of the entire circle and then using that find the length of the arc.

So the circumference of the circle is its radius (11) times pi multiplied by 2.

2(11 x 3.14) = 69.08

Now a circle is always 360 degrees and the angle of the sector is 60 degrees.

So we have our circumference and we only need that small portion, so you take and make it a fraction and multiply by the circumference to find the length of that small portion:

60/360 x 69.08 = 11.51

Rounded = 12

The diameter of the sphere is approximately 20 meters to the nearest tenth of a meter.

The volume of a sphere is given by the formula V = (4/3)πr^3, where r is the radius of the sphere. Since we are given the volume of the sphere, we can solve for the radius as follows:

V = (4/3)π[tex]r^{3}[/tex]

[tex]r^{3}[/tex] = (3V) / (4π)

r = [tex](3V/4\pi )^{1/3}[/tex]

Substituting the given value of the volume, we get:

r = [tex](3*7483/4\pi )^{1/3}[/tex] ≈ 10.0

Therefore, the radius of the sphere is approximately 10 meters. The diameter of the sphere is twice the radius, so the diameter is approximately:

There are 20 different ways to assign five students to cover the morning and afternoon shifts at the food pantry.

There are different methods to solve this problem, but one possible way is to use a combination of counting techniques.

Since there are two shifts (morning and afternoon) and each shift must be covered by at least two students, there are two cases to consider:

Case 1: Two students cover the morning shift, and three students cover the afternoon shift.

Case 2: Three students cover the morning shift, and two students cover the afternoon shift.

For Case 1, we can choose two students out of five for the morning shift in C(5,2) = 10 ways, and the remaining three students will cover the afternoon shift. For each of the 10 ways of selecting the morning shift, we can choose three students out of the remaining three for the afternoon shift in C(3,3) = 1 way (since there are only three students left). Therefore, there are 10 x 1 = 10 ways to assign the students for Case 1.

For Case 2, we can choose three students out of five for the morning shift in C(5,3) = 10 ways, and the remaining two students will cover the afternoon shift. For each of the 10 ways of selecting the morning shift, we can choose two students out of the remaining two for the afternoon shift in C(2,2) = 1 way (since there are only two students left). Therefore, there are 10 x 1 = 10 ways to assign the students for Case 2.

The total number of ways to assign the students is the sum of the ways for Case 1 and Case 2, which is 10 + 10 = 20 ways.

To calculate the total amount Tabitha might pay for the SUV with a 7-year loan, we are able to use the compound interest formula for calculating the total amount of a loan, that is:

[tex]total amount = principal x (1 + interest charge)^{time}[/tex]

Wherein:

With a 7-year loan, the full amount Tabitha could pay is:

[tex]total amount = $29,000 x (1 + 0.043)^{7} = $37,501.76[/tex]

To calculate the overall amount she could pay with a 5-year loan and a 5% decrease interest rate, we first need to calculate the new interest price. A 5% discount inside the interest price of 4.3% is:

New interest price = 4.3% - 5% = 3.3%

The correct approach would be to use the formula for the volume of a sphere:

Since Wesley's tank has a diameter of 30 cm, its radius is 15 cm. Substituting this value into the formula gives:

V = (4/3)π(15)^3

V ≈ 14,137 cm^3

To find the radius of the smaller tank with half the volume, Kate should have solved for the radius using the formula for the volume of a sphere:

The area of the King-sized mattress is 4,800 square inches and the area of the Queen-sized mattress is 3,200 square inches.

To find the dimensions of the Queen-sized mattress, let x be the width. Then, the length of the mattress is x + 16. The area of the Queen-sized mattress is x(x + 16) = x² + 16x.

Since the King-sized mattress has the same length as the Queen-sized mattress, its length is x + 16. Also, its width is 20 inches wider than the Queen-sized mattress, so its width is x + 16 + 20 = x + 36. Therefore, the area of the King-sized mattress is (x + 16)(x + 36) = x² + 52x + 576.

The area of the King-sized mattress is 1,600 square inches larger than the area of the Queen-sized mattress. So, we can set up the following equation:

x² + 52x + 576 - (x² + 16x) = 1600

Simplifying this equation, we get:

36x + 576 = 1600

36x = 1024

x = 28

Therefore, the width of the Queen-sized mattress is 28 inches and the length is 44 inches. So, its area is 3,200 square inches.

[tex]y = \sqrt{x - 6} + 5[/tex]

Step 2: Swap y and x

[tex]x = \sqrt{y - 6} + 5[/tex]

Solve for y.

[tex]x - 5 = \sqrt{y - 6} [/tex]

[tex](x - 5) { }^{2} + 6 = y[/tex]

Step 4: Let y =f^-1(x)

[tex](x - 5) {}^{2} + 6 = f {}^{ - 1} (x)[/tex]

Answer: [tex]f^{-1}(x) =[/tex] x²-10x+19

Step-by-step explanation:

Let's replace f(x) for y for now.

[tex]y=\sqrt{x-6}+5[/tex]

To find inverse.  make your y into x, and your x into y

[tex]x=\sqrt{y-6}+5[/tex]        >Now you solve for y.  subtract 5 from both sides

[tex]x-5=\sqrt{y-6}[/tex]        >Square both sides to get rid of root

[tex](x-5)^{2} =(\sqrt{y-6})^{2}[/tex]     >drop root and square (x-5)

(x-5)(x-5) = y-6              >FOIL

x²-5x-5x+25 = y-6        > combine like terms

x²-10x+25 = y-6            >add 6 to both sides

x²-10x+19=y            > this is your inverse now put the y into inverse form

[tex]f^{-1}(x) =[/tex] x²-10x+19
