Let x be the time passed, in hours.

Let y be the amount of fluid left in the IV, in mL.

If fluid drips at a rate of 300 ml per hour.

And 1400 ml of fluid remain after 2 hours.

The linear function can be modeled as:

Step-by-step explanation:

The intervals on which a quadratic function is positive are those intervals where the function is above the x-axis, i.e. where y > 0.

The zeros of the quadratic function are the points at which the parabola crosses the x-axis.  

If the leading coefficient of a quadratic function is positive, the parabola opens upwards.

If the leading coefficient of a quadratic function is negative, the parabola opens downwards.

Therefore, to find the intervals on which each quadratic function is positive:

Given function:

\(y=x^2+2x-8\)

Factor the given function:

\(\implies y= x^2+4x-2x-8\)

\(\implies y=x(x+4)-2(x+4)\)

\(\implies y=(x-2)(x+4)\)

Substitute y = 0 to find the zeros:

\(\implies (x-2)(x+4)=0\)

\(\implies x-2=0 \implies x=2\)

\(\implies x+4=0 \implies x=-4\)

The leading coefficient is positive, so the parabola opens upwards.  

Therefore, the interval on which the function is positive is:

Given function:

\(y=-x^2+4x+12\)

Factor the given function:

\(\implies y=-(x^2-4x-12)\)

\(\implies y=-(x^2-6x+2x-12)\)

\(\implies y=-(x(x-6)+2(x-6))\)

\(\implies y=-(x+2)(x-6)\)

Substitute y = 0 to find the zeros:

\(\implies -(x+2)(x-6)=0\)

\(\implies (x+2)(x-6)=0\)

\(\implies x+2=0 \implies x=-2\)

\(\implies x-6=0 \implies x=6\)

The leading coefficient is negative, so the parabola opens downwards.  

Therefore, the interval on which the function is positive is:

Given function:

\(y=5x^2-3x-8\)

Factor the given function:

\(\implies y=5x^2-8x+5x-8\)

\(\implies y=x(5x-8)+1(5x-8)\)

\(\implies y=(x+1)(5x-8)\)

Substitute y = 0 to find the zeros:

\(\implies (x+1)(5x-8)=0\)

\(\implies x+1=0 \implies x=-1\)

\(\implies 5x-8=0 \implies x=\dfrac{8}{5}\)

The leading coefficient is positive, so the parabola opens upwards.  

Therefore, the interval on which the function is positive is:

The approximate diameter of the circle is 5.77 cm

Given that :

area of circle = 28.3 cm²

How is Area of circle is calculated ?

Area of circle is calculated using formula :

A= πr²

where "π" represents 3.14 and r is radius. So now, according to given information,

Where Pi = 3.14

Hence,

A= πr²

Substitution the value of A in above formula :

28.3 = πr²

28.3 = 3.14r²

r² =28.3/3.14

r² =8.323

√r²=√8.323

r = 2.885

r = 2.885 cm Approximately.

The result of the matrix equation is not specified in the given problem statement. Instead, we are given some information about a real, symmetric matrix with two distinct eigenvalues and are asked to calculate a certain expression involving this matrix.

For real, symmetric matrices with distinct eigenvalues, it is known that the eigenvectors corresponding to these eigenvalues are orthogonal. This means that if we let v1 and v2 be the eigenvectors corresponding to the two distinct eigenvalues of our matrix A, then v1 and v2 are orthogonal (i.e., their dot product is zero).

To calculate the expression , we need to find the dot product of the two vectors A^(-1)v1 and v2. Using the fact that A is symmetric and has distinct eigenvalues, we can show that A is diagonalizable. That is, there exists an invertible matrix P such that P^(-1)AP = D, where D is a diagonal matrix with the eigenvalues of A on the diagonal. Multiplying both sides of this equation by P^(-1), we get AP^(-1) = P^(-1)DP, which shows that the columns of P^(-1) are the eigenvectors of A. Therefore, we can find v1 and v2 by computing the first and second columns of P^(-1), respectively. Once we have v1 and v2, we can compute A^(-1)v1 and take the dot product with v2 to get our answer.

The option 2 and 4 is correct ∠IAH = ∠EAD and ∠EDG = ∠FDA these angle are vertical to each other

Vertically opposite angles are a pair of angles formed by the intersection of two straight lines. When two lines intersect, four angles are formed at the point of intersection. Vertically opposite angles are formed by two non-adjacent angles that lie across from each other and share the same vertex, or corner point, at the intersection of the two lines.

Line IC and Line GH intersect each other at A

∴ ∠IAH = ∠EAD (vertacally opposite angle)

Similarly, Line FB and Line GH intersect each other at D

The hotel owner needs approximately 2,248 square feet of fabric to make a pool covering for the winter for their regular hexagonal pool with a side-to-side length of 30 feet.

To calculate the area of the pool, we first need to find the apothem (the distance from the center of the hexagon to the midpoint of any side). For a regular hexagon, the apothem is equal to the side length times the square root of 3 divided by 2. So, the apothem of this hexagonal pool is:

apothem = 30 × √3/2 = 25.980762

The area of a regular hexagon is given by the formula:

area = 3 × √3/2 × apothem^2

Substituting the value of the apothem, we get:

area = 3 × √3/2 × 25.980762^2 = 2247.72

Rounding this to the nearest square foot, the hotel owner will need approximately 2,248 square feet of fabric to construct the cover for the pool.

Answer:

Step-by-step explanation:

The weight of the fish tank when it is empty, given the the dimensions of the water, is 44 pounds.

First, let's find the weight of the water in the fish tank.

Convert the dimensions of the water inside the fish tank from inches to feet:

34 inches = 34/12 = 2.83 feet

13 inches = 13/12 = 1.08 feet

Calculate the volume of the water in cubic feet:

Volume = length × width × height

Volume = 2.83 ft × 1.08 ft × 1.08 ft = 3.3 cubic feet

Calculate the weight of the water in the fish tank using the given weight of 1 cubic foot of water (62.4 pounds):

Weight of water = Volume × Weight per cubic foot

Weight of water = 3.3 cubic feet × 62.4 pounds/cubic foot = 206 pounds

Now that we have the weight of the water, we can find the weight of the empty fish tank.

Weight  = Weight of tank + Weight of water

Weight of tank  = Weight - Weight of water

Weight  = 250 pounds - 206 pounds

The margin of error for the survey, rounded to the nearest tenth, is approximately 4.0% when expressed as a percentage.

To determine the margin of error for a survey at the 95% confidence level, we need to calculate the standard error. The margin of error represents the range within which the true population proportion is likely to fall.

The formula for calculating the standard error is:

Standard Error = sqrt((p * (1 - p)) / n)

where p is the sample proportion and n is the sample size.

In this case, the sample proportion is 64% (or 0.64) since 64% of the 1350 surveyed residents support the plan.

Plugging in the values:

Standard Error = \(\sqrt{(0.64 * (1 - 0.64)) / 1350)}\)

\(= \sqrt{(0.2304 / 1350)} \\= \sqrt{(0.0001707)}\)

≈ 0.0131

Now, to find the margin of error, we multiply the standard error by the appropriate critical value for a 95% confidence level. The critical value corresponds to the z-score, which is approximately 1.96 for a 95% confidence level.

Margin of Error = z * Standard Error

= 1.96 * 0.0131

≈ 0.0257

Finally, to express the margin of error as a percentage, we divide it by the sample proportion and multiply by 100:

Margin of Error as Percentage = (Margin of Error / Sample Proportion) * 100

= (0.0257 / 0.64) * 100

≈ 4.0%

Therefore, the margin of error for this survey, expressed as a percentage to the nearest tenth, is approximately 4.0%.

(a). The radian measure of angle A is 6 radians.

(b). The radian measure of angle B is 3 radians.

(c). The radian measure of angle C is 2 radians.

What is relation between radian and degree?

A circle's whole angle is 360 degrees and two radians. This serves as the foundation for converting angles' measurements between different units. This means that a circle contains an angle whose radian measure is 2 and whose central degree measure is 360. This can be written as:

2π radian = 360° or

π radian = 180°

(a). Evaluate the radian measure of angle A:

Near to 360° and radians measure whole number, so we get,

A = 6 radian {1 radian = 57.296°}.

(b). Evaluate the radian measure of angle B:

Near to 180°, and radian measure whole number, so we get,

B = 3 radian

(c). Evaluate the radian measure of angle C:

Near to 90 and radian measure whole number, so we get,

C = 2 radian.
