Thus, the mass of the frog is 48.6π grams when it is in a hemispherical pod which just floats without sinking into sea water.

The force imposed on a body by a fluid, such as water or air, in which the body is submerged or immersed is known as buoyancy. This force is equivalent to the mass of the fluid that the body has displaced. In mathematics, buoyancy is defined as the sum of the fluid density, gravitational acceleration, and body volume. Archimedes' principle, which asserts that the buoyant force on an item is equal to the weight of the fluid it displaces, is a name for this connection. A key idea in the study of fluid mechanics, buoyancy has many uses, including the construction of boats, planes, and other floating structures.

How to solve?

V = 2/3 * π * r^3,

V = 2/3 * π * 6^3 = 2/3 * π * 216 = 36π.

F = V * d,

F = 36π * 1.35g/c * m^3 = 48.6π g.

F = m + W,

48.6π g = m + 0 g.

m = 48.6π g.

Answer:

(a) 21, 22, 23

(b) 11, 13, 15

Step-by-step explanation:

Natural numbers are the set of numbers 1, 2, 3... Not numbers that we think of as fractions or decimals or negative numbers.

Let x = the first number

Let x+ 1 = the second number

Let  x+ 2 = the third number

x + x+ 1 + x + 2 = 66  Combine like terms

3x + 3 = 66  Subtract 3 from both sides

3x = 63  Divide both sides by 3

x = 21

Check:

21 + 22 + 23 = 66

Let x + the first number

Let x + 2 = the second number

Let x + 4 = the thirds number

x + x + 2 + x + 4 = 39  Combine like terms

3x + 6 = 39  Subtract 6 from both sides

3x = 33  Divide both sides by 3

x = 11

Check:  11 =+ 13 + 15 = 39

The standard form of the parabola is   x = -4/3y² -40/3y -103/3

What is parabola?

A parabola is an approximately U-shaped, mirror-symmetrical planar curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. One way to describe a parabola is with a point and a line.

 x = -4/3(y +5)² -1

Solve for x.

 x = (4y² +40y +103)/(-3)

 x = -4/3y² -40/3y -103/3 . . . . 'standard form' in the US

__

Taking our clues from the graph*, we can write the vertex form equation as ...

 x = -4/3(y +5)² -1 . . . . . . 'standard form' in other places

____

* The vertex is (-1, -5), so for some leading coefficient, the equation will be ...

 x = a(y -(-5))² +(-1) = a(y +5)² -1

The value of 'a' is the scale factor. Here, that is the difference between the parabola value (x = -2 1/3) and the vertex value (x = -1) one unit away from the vertex.

The dimensions of a building to be fenced off around a rectangular parcel of land are 10.5 meters and 21 meters.

The Latin word rectus, which meaning "right" or "straight," is the source of the English word "rectangle." The straight sides of a rectangle are a result of its right angles. Rectitude, which refers to moral uprightness, is another term with the same root.

Explanation:

The size of a rectangle

lw = area of rectangle

where,

= length

= width

Thus, perimeter equals 2w plus l.

42 = 2w + l

l = 42 - 2w

Hence,

area = w (42- 2w)

180 = 42w - 2w²

-2w² +42w - 180 = 0

-w² + 21w - 180 = 0

The following is where to find the dimension w;

w = - b / 2a

where

a = -1

b = 21

w = - 21 / 2 × -1

W=10.5 meters.

Then,

l = 42 - 2w

l = 42 - 2(10.5) (10.5)

l=21 meters .Consequently, the measurements are 10.5 meters and 21 meters.

The account balance(i.e. compound amount) will be $5706.84 after 28 years.

What is daily compounded interest?

Daily compounded interest is defined as an interest that is accrued daily and is computed by charging interest on principal plus interest earned daily. Due to the frequent compounding, daily compounded interest is higher than interest compounded on a monthly or quarterly basis.

Given, Principal = $2834

the annual rate = 2.5% = 0.025

time = 28 years

For compounded daily, n = 365

Now, the compound amount is calculated by

[tex]A = P(1 + \frac{r}{n} )^{nt}[/tex]

or, A = [tex]2834(1 + \frac{0.025}{365} )^{365*28}[/tex]

A time of 40.7 minutes is taken for 170 grams of element X to decay to 5 grams.

What is radioactive decay?

The release of energy in the form of ionizing radiation occurs during radioactive decay.

                       Ionizing radiation can harm DNA in genes and tissues because it can affect the atoms in living things.

We know that decay behaves exponentially and follows this model

   [tex]m(t) = m_{0} . e^{t/T} \\[/tex]

The time constant can be described in terms of half-life (t1/2), in minutes, through the following expression

     T =  t1/2 /In2

If we know that t1/2 = 8 min , m₀ = 170g and m(t) = 5g then the time needed for the decay is:

τ ≈ 11.541 min

   t = -τ .In m(t)/m₀

t ≈ 40.698 min

The measure of the given angle ∠BDC or x is 55°.

An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint.

The Latin word "angulus," which means "corner," is the source of the English term "angle."

The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle.

The names of fundamental angles include acute, obtuse, right, straight, reflex, and full rotation.

A geometrical shape called an angle is created by connecting two rays at their termini.

In most cases, an angle is expressed in degrees.

So, we know that:

∠ABC = 80°

∠ABD = 25°

∠BDC = x°

Calculate for ∠BDC:

∠ABC - ∠ABD = ∠BDC

80 - 25 = x

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the equation A is

65% of a number is 208 and 15% of the same number is 48

So , 65% of n = 208   be equation (1)

15% of n = 48   be equation (2)

Now , on simplifying the equations , we get

( 15 / 100 ) x n = 48

15n/100 = 48

Multiply both sides by 100 . we get

15n = 4800

Divide by 15 on both sides of the equation , we get

n = 320

The number n can also be determined by

( 65% - 15% ) of n = 208 - 58

50 % of n = 160

So , 100 % on n = 160 x 2

n = 320

Therefore , the number n is 320

Now , the 80 % of the number n is A = 80/100 x 320

A = 320 x 0.8

A = 256

Therefore , the value of A is 256

The equation of the line which is perpendicular to 5x - 4y = 16 is  [tex]y = -\frac{4}{5}x -4[/tex].

The study of geometry using coordinate points is known as coordinate geometry (also known as analytical geometry). Finding the distance between two points, breaking lines into m:n segments, locating a line's midpoint, computing a triangle's area in the Cartesian plane, and other operations are all feasible using coordinate geometry.

Not all crossing lines are parallel ones. If the intersecting lines satisfy the following conditions, they are said to be perpendicular lines. Following are the two primary characteristics of perpendicular lines:

Let's say that lines AB and CD are parallel to one another. Line AB has a slope of m1, whereas line CD has a slope of m2.

If and only if the product of the slopes of the two lines equals negative of unity, two lines are perpendicular to one another.

As a result, the following is the formula for the perpendicular's slope:

m1.m2 = -1

The equation of the line be "y = mx + c".

Equation of the line Perpendicular to the line is 5x - 4y = 16

Therefore,  4y = 5x - 16

⇒ [tex]y = \frac{5}{4}x -4[/tex]

Slope of the line Perpendicular to the required line is [tex]\frac{5}{4}[/tex].

Slope of the required ine be m .

Therefore, m * [tex]\frac{5}{4} = -1[/tex]

⇒ [tex]m = -\frac{4}{5}[/tex].

Equation of the line is ,

[tex]y = -\frac{4}{5}x + c[/tex]
