x = (12 ± √(-16)) / 4,The solutions would be complex numbers.

To solve quadratic equations of the form ax2 + bx + c = 0, use the quadratic formula. For this situation, your condition is as of now as a quadratic condition, with a = 2, b = - 12, and c = 20.

The quadratic formula is:

x = (-b ± √\((b^2 - 4ac)\)) / 2a

Plugging in the values for a, b, and c, we get:

x = (-(-12) ± √\(((-12)^2 - 4(2)(20)))\) / 2(2)

Simplifying the expression inside the square root:

x = (12 ± √\((144 - 160)\)) / 4

x = (12 ± √(-16)) / 4

Since the square foundation of a negative number is definitely not a genuine number, this condition has no genuine arrangements. Complex numbers would provide the answers.

Answer:

11.6 years

Step-by-step explanation:

Given

\(A=P(1+\frac{r}{n} )^{nt}\)

we can solve for \(t\)

\(t=\frac{ln(\frac{A}{P} )}{n*ln(1+\frac{r}{n}) }\)

We are given

\(A=1800\\P=900\\r=0.06\\n=12\)

Simply multiply all of the fractions with the total number of marbles

48(2/3)(3/4)

\( \sf \longrightarrow \: 5 \bigg( \: n - \frac{1}{10} \bigg) = \frac{1}{2} \\ \)

\( \sf \longrightarrow \: 5 \bigg( \: \frac{n}{1} - \frac{1}{10} \bigg) = \frac{1}{2} \\ \)

\( \sf \longrightarrow \: 5 \bigg( \: \frac{10 \times n - 1 \times 1}{1 \times 10} \bigg) = \frac{1}{2} \\ \)

\( \sf \longrightarrow \: 5 \bigg( \: \frac{10n - 1}{ 10} \bigg) = \frac{1}{2} \\ \)

\( \sf \longrightarrow \: \: \frac{50n - 5}{ 10} = \frac{1}{2} \\ \)

\( \sf \longrightarrow \: \: 2(50n - 5) =1(10) \\ \)

\( \sf \longrightarrow \: \: 2(50n - 5) =10 \\ \)

\( \sf \longrightarrow \: \: 100n - 10=10 \\ \)

\( \sf \longrightarrow \: \: 100n =10 + 10\\ \)

\( \sf \longrightarrow \: \: 100n =20\\ \)

\( \sf \longrightarrow \: \:n = \frac{2 \cancel{0}}{10 \cancel{0}} \\ \)

\( \sf \longrightarrow \: \:n = \frac{1}{5} \\ \)

Answer:-

To solve the equation \(\sf 5(n - \frac{1}{10}) = \frac{1}{2} \\\) for \(\sf n \\\), we can follow these steps:

Step 1: Distribute the 5 on the left side:

\(\sf 5n - \frac{1}{2} = \frac{1}{2} \\\)

Step 2: Add \(\sf \frac{1}{2} \\\) to both sides of the equation:

\(\sf 5n = \frac{1}{2} + \frac{1}{2} \\\)

\(\sf 5n = 1 \\\)

Step 3: Divide both sides of the equation by 5 to isolate \(\sf n \\\):

\(\sf \frac{5n}{5} = \frac{1}{5} \\\)

\(\sf n = \frac{1}{5} \\\)

Therefore, the solution to the equation \(\sf 5(n - \frac{1}{10})\ = \frac{1}{2} \\\) is \(\sf n = \frac{1}{5} \\\), which corresponds to option (d).

At a temperature of 20°C, the mouse would burn approximately 1,567.44 calories each day.

According to the given model C = 0.37219T + 1,560, where C represents the number of calories an idle mouse burns each day and T represents the temperature of its environment in °C.

To find the most comfortable temperature for an idle mouse, we need to determine the temperature at which the mouse burns the least amount of calories per day.

To find this temperature, we can minimize the equation C = 0.37219T + 1,560. To do so, we take the derivative of C with respect to T and set it equal to zero:

dC/dT = 0.37219 = 0

Solving this equation, we find that the derivative is a constant value, indicating that the function C = 0.37219T + 1,560 is a linear equation with a slope of 0.37219. This means that the mouse burns the least calories at any temperature, as the slope is positive.

Therefore, there is no specific "most comfortable" temperature for an idle mouse in terms of minimizing calorie burn. However, if we consider the range of temperatures mice typically encounter, we can find a temperature where the calorie burn is relatively low.

For example, if we take a temperature of 20°C, we can calculate the calorie burn:

C = 0.37219 * 20 + 1,560

C = 7.4438 + 1,560

C ≈ 1,567.4438 calories per day

Therefore, at a temperature of 20°C, the mouse would burn approximately 1,567.44 calories each day.

At x=3 to x=7, the average rate of change of the given function

f(x) = x2- 4x + 1 is 6.

Given function,

    f(x) = x² - 4x + 1

given x=3 and x=7

To find the average rate of change of a function, find its slope(m),

To find m ,

               m= (y2 - y1) / (x2 - x1)

here y1 and y2 not given.

then substitute the given values of x into f. (x)

when x=3 ,

          y1 = (3² - 4×3 +1)

              = (9 - 12 +1)

              =  -2

so (x1,y1) = (3,-2)

similarly to find y2,

substitute x = 7 to f(x)

            y2 = (7² - 4×7 + 1)

                 = (49 - 28 +1)

                 = 22

so (x2,y2) = (7,22)

To find m, substitute the values.

  m= (y2 - y1) / (x2 - x1)

            = (22 -( - 2)) / (7 - 3)

           = 24/4

           = 6

As a result, the average rate of change of the function x2-4x + 1 is 6.

The distance between two points can be calculated using the formula distance = \(√((x2 - x1)2 + (y2 - y1)2)\).

The formula to calculate the distance between two points, (x1, y1) and (x2, y2), is given by the distance equation:

distance = \(√((x2 - x1)2 + (y2 - y1)2)\).

To calculate the distance, first subtract the x-coordinates of the two points, square the result, and add it to the square of the difference of the y-coordinates. Then take the square root of the sum.

For example, if we want to calculate the distance between points (2, 3) and (5, 7), we first subtract the x-coordinates and get (5 - 2) = 3. Then we square 3 and get 9. We then subtract the y-coordinates, (7 - 3) = 4, and square the result, getting 16. We then add 9 and 16 to get 25 and take the square root of 25 to get 5. Therefore, the distance between (2, 3) and (5, 7) is 5.

Therefore, the distance between two points can be calculated using the formula distance = \(√((x2 - x1)2 + (y2 - y1)2).\)

All squares are rectangles. Rectangles have 4 right angles. Therefore, all squares have 4 right angles.

All recatangles have 4 angles which are 90°. Though all squares are rectangles, remember, not all rectangle are squares

Hope this helps, Bye!

The true statement is "All squares are rectangles. Rectangles have 4 right angles. Therefore, all squares have 4 right angles".

That rectangle whose all sides are equal is called a square.

A square has its diagonals perpendicular bisector to each other and is of the same length. (this is actually a characteristic property, which means that if a quadrilateral has its diagonals equal and perpendicular,

then it is a square for sure).

A square is always a rectangle, parallelogram, a rhombus, and a quadrilateral but its reverse statement may or may not be true.

also, it is not always necessary that a rectangle is a square or a parallelogram is a square or a rhombus is a square.

All squares are rectangles. Rectangles have 4 right angles.

By applying the Newton's law of cooling and performing the neccessary calculations, the time of death of the body is about 4 hours ago.

According to the Newton's law of cooling;

T(t) = T(s) + (To - Ts)e^-kt

T(t) = temperature at time t

T(s) = temperature of the surroundings

To = Initial temperature

k = cooling constant

t = time taken

Substituting the values;

T(t) = 60 + (98.6 - 60)e^- 0.1947t

To find the time taken to attian a temperature of 78°F;

78 = 60  + (98.6 - 60)e^- 0.1947t

78= 60 + 38.6e^- 0.1947t
