9. Find the point on the parabola 2y = x? that is closest to the point (-4,1).

The four corners of a square are 90 degrees.

They are evenly split by the diagonal lines, so each corner is now two 45 degree angles.

The lines form triangles, which have 3 angles that need to equal 180 degrees.

Two of the angles are 45, so 45 + 45 = 90 degrees.

X = 180 -90 = 90 degrees.

Answer:

90 degrees

By 90 * 4 is 360

Step-by-step explanation:

there is to be a stage 15m wide and 3m deep with a curved seating area as shown

Determine the area of the seating area?

Answer:

Yes, the are the right degrees.

Answer:

I do agree

Step-by-step explanation:

I know 10. is right because it is a right angle which id usually 90 degrees.

I'm pretty sure 11. is right because I know it is an obtuse angle and I think the number you gave is close if not it.

I know 12. is right because that angle looks the same as DBA which is already labeled 54 degrees.

I know 13.  is right because 180 degrees is always a straight line.

Answer:

b = 3

Step-by-step explanation:

Given that,

→ a = 27

Forming the equation,

→ 27 = 3b²

Now the value of b will be,

→ 27 = 3b²

→ b² = 27/3

→ b = √9

→ [ b = 3 ]

Hence, the value of b is 3.

⇒Given that a=27 in the equation \(a=3b^{2} \\\) in the place of a plug in 27 and solve for b

\(27=3b^{2} \\\frac{27}{3} =\frac{3b^{2}}{3} \\b^{2} =9\\b^{2}-9=0\\(b+3)(b-3)=0\\b+3=0\\or\\b-3=0\\b=-3\\or\\b=3\)

⇒Note b can also be -3 but the only option available as the answer is 3

∴ b=3 in this case.

The amount of medicine that will remain in the system after 6 hours is 27.44 milligrams.

Initial condition = 50 milligrams of medicine,

Rate at which medicine will be disposed = 10% = 0.1

function = \(A(t) = I \times e^{rt}\)

Medicine remains in the system after 6 hours

As the function is already given to us, substituting the values in the function we get,

\(A(t) = I \times e^{rt}\)

\(A(t) = (50) \times e^{(-0.1\times 6)}\)

the value of r is -0.1(10%) because the medicine is leaving the system, therefore, the value of medicine will be reduced.

Solving the function further,

\(A(t) = (50) \times e^{(-0.1\times 6)}\\A(t) = 27.44\ milligrams\)

Hence, the amount of medicine that will remain in the system after 6 hours is 27.44 milligrams.

No function f(r,θ) is given, we cannot evaluate the integral further.

To write ∬rfda as an iterated integral in polar coordinates for the given region rr, we need to determine the limits of integration for r and θ.

Let's first look at the region rr. From the given graph, we can see that the region is bounded by the circle with radius 3 centered at the origin. Therefore, we can express the region as:

r ≤ 3

To determine the limits for θ, we need to examine the region rr more closely. We can see that the region is symmetric about the x-axis, which means that the limits for θ are:

0 ≤ θ ≤ π

Now, we can write the iterated integral as:

∬rfda = ∫₀³ ∫₀ᴨ f(r,θ) r dθ dr

where f(r,θ) is the integrand function and r and θ are the limits of integration. Note that r is integrated first, followed by θ.

In this case, since no function f(r,θ) is given, we cannot evaluate the integral further.

Step-by-step explanation:

Volume of ice =   10 X 10 X 20 = 2000 cm^3

tank volume increase will be the same

   100 x 40 x HEIGHT = 2000

            Height = 2000/ ( 100 X 40) =  .5 cm height increase

The melting of the ice block would raise the water level in the tank by approximately 0.5 centimeters. This can be answered by the concept of Volume

To calculate the amount of water that would be displaced by the ice block, we need to first find its volume, which is 10 x 10 x 20 = 2000 cubic centimeters. Since 1 cubic centimeter of water has a mass of 1 gram, the mass of the ice block would be 2000 grams or 2 kilograms.

When the ice block melts, it will turn into water and occupy the same volume, which would displace an equal amount of water in the tank. The volume of the tank is 100 x 40 x h, where h is the increase in water level. Setting the volume of the ice block equal to the increase in the water level, we get:

2000 = 100 x 40 x h

h = 0.5 centimeters

Therefore, the melting of the ice block would raise the water level in the tank by approximately 0.5 centimeters.

The converse of the statement "If a figure is a square, its diagonals divide it into isosceles triangles" would be:

"If a figure's diagonals divide it into isosceles triangles, then the figure is a square."

The converse statement is not necessarily true. While it is true that in a square, the diagonals divide it into isosceles triangles, the converse does not hold. There are other shapes, such as rectangles and rhombuses, whose diagonals also divide them into isosceles triangles, but they are not squares. Therefore, the converse of the statement is not always true.

Therefore, the converse of the given statement is not true. The existence of diagonals dividing a figure into isosceles triangles does not guarantee that the figure is a square. It is possible for other shapes to exhibit this property as well.

In conclusion, the converse statement does not hold for all figures. It is important to note that the converse of a true statement is not always true, and separate analysis is required to determine the validity of the converse in specific cases.

The difference between a bar graph and a histogram is that of  b. a bar graph displays categorical data, while a histogram displays quantitative data.

A bar graph is majorly used to compare different categories or groups of data. It displays data in separate bars, each representing a different category. A histogram, on the other hand, is used to display the distribution of a continuous quantitative variable. It shows the frequency of different values within a range of values by using bars of different heights. The bars in a histogram are also adjacent to each other, with no space between them.

We can decompose the given rational function as follows:

f(x) = (16x^3 + 12x^2 + 10x + 2) / [(x^4 – 4x^2)(x^2 + x + 1)^2(x^2 – 3x + 2)(x^4 + 3x^2 + 2)]

To find the partial fraction decomposition, we first factor the denominator completely:

x^4 – 4x^2 = x^2(x^2 – 4) = x^2(x – 2)(x + 2)

x^2 + x + 1 = (x + 1/2)^2 + 3/4

x^2 – 3x + 2 = (x – 1)(x – 2)

x^4 + 3x^2 + 2 = (x^2 + 1)(x^2 + 2)

Substituting these factorizations into the denominator, we get:

f(x) = (16x^3 + 12x^2 + 10x + 2) / [x^2(x – 2)(x + 2)(x + 1/2)^2(3/4)^2(x – 1)(x – 2)(x^2 + 1)(x^2 + 2)]

We can now write the partial fraction decomposition as:

f(x) = A/x + Bx + C/(x – 2) + D/(x + 2) + E/(x + 1/2) + F/(x + 1/2)^2 + G/(x – 1) + H/(x^2 + 1) + I/(x^2 + 2)

where A, B, C, D, E, F, G, H, and I are constants to be determined.

Note that the term E/(x + 1/2) has a repeated linear factor (x + 1/2)^2, so we need to include a second term F/(x + 1/2)^2 in the decomposition.

The critical points of f(x) = xin(4x) are x = 0, pi/4, and 3pi/4.

To find the critical points of f(x), we need to find the values of x where the derivative is zero. The derivative of f(x) is f'(x) = (1 - 4x^2)in(4x). Setting this equal to zero and solving for x, we get x = 0, pi/4, and 3pi/4. These are the only values of x where the derivative is zero, so they are the only critical points of f(x).

At x = 0, the function f(x) is undefined. At x = pi/4 and x = 3pi/4, the function f(x) has a local maximum and a local minimum, respectively.

Now we have to,

→ find the volume of the pyramid.

Formula we use,

→ Volume = (1/3)a² × h

Then the volume of pyramid is,

→ (1/3)a² × h

→ (1/3) × (9)² × 7
