Step-by-step explanation:

The motion of the dolphin, evaluated using the kinematic equations and Newton's second law of motion are;

Mathematically, Newton's second law of motion states that force is the product of mass and acceleration.

The mass of the dolphin = 230 kg

Height to which the dolphin leaps = 6.4 m

The distance the drag brings the dolphin to a stop = 6.4 meters

First part;

The time it takes the dolphin to stop can be found from the equation;

At the water surface;

m·g·h = 0.5·m·v² (conservation of energy)

g·h = 0.5·v²

v² = 2·g·h

Therefore;

v² = 2 × 9.81 × 6.4 = 125.568

In the water, the initial velocity is v, the velocity at 1.5 meters depth is u, we get;

u² = v² - 2·a·s

Therefore;

v² = 2·a·s

a = v²/(2·s)

a = 125.568/(2 × 1.5) = 41.856

a = 41.856 m/s²

v = u - a·t

t = (u - v)/a

Therefore;

t = (√(125.568))/41.856 ≈ 0.268

The time it takes the dolphin to stop is about 0.268 seconds

Second part

Newton's second law of motion states that force is directly proportional to the rate of change of momentum produced

Mathematically

Force = Mass × Acceleration

Force on the dolphin, F = 230 kg × 41.856 m/s²= 9626.88 N

The time it would take the rocket to hit the ground upon launch is; 3 seconds.

It follows from the task content that the time taken for the rocket in discuss to hit the ground upon launch is to be determined.

Since the given formula for the height in terms of time, t is;

h = - 3t² + 3t + 18

It follows that ; when the rocket hits the ground; the height; h = 0.

Therefore;

0 = - 3t² + 3t + 18

0 = -3t² + 9t - 6t + 18

0 = -3t ( t - 3 ) - 6 ( t - 3)

-3t - 6 = 0 OR. t - 3 = 0.

The value of x is 19 and the measure of angles in triangle ABC are 75°, 75° and 30° respectively.

triangle is a three-sided polygon that consists of three edges and three vertices. The most important property of a triangle is that the sum of the internal angles of a triangle is equal to 180 degrees. This property is called angle sum property of triangle.

If ABC is a triangle, then it is denoted as ∆ABC, where A, B and C are the vertices of the triangle. A triangle is a two-dimensional shape, in Euclidean geometry, which is seen as three non-collinear points in a unique plane.

The sum of ∠A + ∠B + ∠C = 180°( sum of angles in a triangle )

3x + 18 + 7x - 58 + 2x - 8 = 180°

12x -48° = 180°

12x = 228

x = 228/12

x = 19

but ∠A = 3x + 18, but x = 19

∠A = 3(19) + 18 which is 75°

Also ∠B = 7x -58

∠B = 7(19) - 58 which is 75°

∠C = 2x -8

∠C = 2(19) - 8 which is 30°

In conclusion, the value of x = 19, ∠A = 75°, ∠B = 75° ∠C = 30°

$14587.5 should be deposited today

Compound interest, also called "compounding interest," is the interest on the initial investment as well as the accrued interest on that investment.

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited.

From the information given,

A = 25000

r = 8% = 8/100 = 0.08

n = 1 because it was compounded once in a year.

t = year

Therefore, substituting the values into the formula

25000 = P(1 + 0.08/1)^1 × 7

25000 = P(1.08)^7

25000 = 1.7138P

P = 25000/1.7138

P = $14587.5

Hence, the amount that should be deposited is $14587.5

To find equivalent expression in math is the fractions with distinct numerators and denominators but the same value are said to be equivalent fractions.

In mathematics, equivalent fractions are those with the same denominator and differing numerators.

The multiplicity of a member of a multiset in mathematics is the number of times the member appears in the multiset. The multiplicity of a root, for instance, is how many times a given polynomial has a root at a particular point.

It's crucial to understand the concept of multiplicity in order to correctly count without mentioning exceptions (for example, double roots counted twice). Thus, "counted with multiplicity" is used.

This can be highlighted by counting the number of different elements, as in "the number of separate roots," if multiplicity is disregarded. However, multiplicity is always taken into account when a set (as opposed to a multiset) is established, therefore the word "different" is not necessary.

What is similar triangles?

To put it another way, similar triangles have the same shape but may differ in size. In addition, if the corresponding sides of the triangles are identical in length, the triangles are congruent.
