What is the condition for a triangle whose two sides are 6cm 8cm then the third side is?

The total distance travelled on the cycle is 30.46m and the acceleration  is the last 8 seconds is 0.85 m/s².

"Acceleration is the measure of the speed at which velocity changes."

OR "Acceleration depends upon the velocity if the velocity continously increases or decreases the acceleration will be produced."

Positive acceleration results from continuously increasing velocity.

Negative acceleration will be negative if the velocity is continuously decreasing.

FORMULA

Acceleration is defined as a change in velocity divided by time, or a = (Vf-Vi)/t UNIT.

Meter/second+square, or m/S², is the SI unit of velocity in the MKS system.

a. Total distance = Hypotenuse₁ + mid distance + Hypotenuse₂

Hypotenuse₁ = [tex]$ \sqrt{10^2 + 6^2} $[/tex]

Hypotenuse₁ = 11.66m

mid distance = 12 - 6

                      = 6m

Hypotenuse₂ = [tex]$ \sqrt{10^2 + (20-12)^2} $[/tex]

Hypotenuse₂ = [tex]$ \sqrt{10^2 + (8)^2} $[/tex]

Hypotenuse₂ = 12.80m

Total distance = 11.66m + 6m + 12.80m

Total distance = 30.46m

b. Acceleration  [tex]{\displaystyle ={\frac { \text{v - u} }{t}}[/tex]

[tex]\displaystyle = {\frac { \text{12.80 - 6} }{8}[/tex]

[tex]\displaystyle = {\frac { 6.80 }{8}[/tex]

0.85 m/s²

Thus, the total distance travelled on the cycle is 30.46m and the acceleration  is the last 8 seconds is 0.85 m/s².

The sine function that intersects its midline at (0,-6) and then has a minimum point at (2.5,-9) is given as follows:

y = 3sin(0.6πx) - 6.

The standard definition of the sine function is given as follows:

y = Asin(Bx) + C.

For which the parameters are given as follows:

The midline is at y = -6, while the minimum point is at y = -9, hence the amplitude of the function is given as follows:

A = -6 - (-9)

A = 3.

A sinusoidal function with amplitude 3 should oscillate between -3 and 3, while it oscillates between -3 and -9, hence the vertical shift is given as follows:

C = -6.

The distance from the midline to the minimum value is of 3/4 of the period, hence the period is of:

3/4P = 2.5

P = 4 x 2.5/3

P = 10/3.

This means that the parameter b is obtained as follows:

2π/B = 10/3

10B = 6π

B = 0.6π

This means that the function is defined as follows:

y = 3sin(0.6πx) - 6.

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{3}{4}[/tex] x - 1 ← is in slope- intercept form

with slope m = [tex]\frac{3}{4}[/tex]

• Parallel lines have equal slopes , then

y = [tex]\frac{3}{4}[/tex] x + c ← is the partial equation of the parallel line

to find c substitute (8, 4 ) into the partial equation

4 = [tex]\frac{3}{4}[/tex] (8) + c = 6 + c ( subtract 6 from both sides )

- 2 = c

y = [tex]\frac{3}{4}[/tex] x - 2 ← equation of parallel line

---------------------------------------------------------------

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{3}{4} }[/tex] = - [tex]\frac{4}{3}[/tex] , then

y = - [tex]\frac{4}{3}[/tex] x + c ← is the partial equation of the perpendicular line

to find c substitute (8, 4 ) into the partial equation

4 = - [tex]\frac{4}{3}[/tex] (8) + c = - [tex]\frac{32}{3}[/tex] + c ( add [tex]\frac{32}{3}[/tex] to both sides )

4 + [tex]\frac{32}{3}[/tex] = c , then

c = [tex]\frac{44}{3}[/tex]

y = - [tex]\frac{4}{3}[/tex] x + [tex]\frac{44}{3}[/tex] ← equation of perpendicular line

The interval should be 12 hours and 25 minutes for the two high tides and two low tides.

What is interval ?

An interval refers to the amount of time it takes for a tide to go from high to low or low to high

The reason for two high tides and two low tides each day is due to the gravitational pull of the moon and the sun on Earth's oceans. These gravitational forces cause the water in the oceans to bulge, creating high tides. The gravitational pull of the moon is stronger than that of the sun, so the moon has a greater impact on tides.

The time it takes for the tide to go from high to low and back to high is called the tidal period, which is about 12 hours and 25 minutes. This is not exactly 24 hours because the Earth is also rotating on its axis, so the position of the Moon and the Sun relative to a specific location on the Earth's surface is constantly changing.

So, the interval should be 12 hours and 25 minutes for the two high tides and two low tides.

The area of the region enclosed by the inner loop of the curve can be calculated by integrating the function r = 6 + 12 sin θ over the interval of θ.

The area of the inner loop is given by Area = 1/2 ∫r^2 dθ = 1/2 ∫(6 + 12 sin θ)^2 dθ

We can solve this integral by breaking it into two parts: Area = 1/2 (∫(6 + 12 sin θ)^2 dθ) = 1/2(∫36 + 72sin θ + 144sin^2 θ dθ)

The first integral is simple and equals to 36*θ and the second one is equal to 48θ - 48cos(2θ)

The limits of integration are [0, 2π]

So the area of the inner loop is 1/2(36*2π + 48(2π) - 48(2)) = 72π

So the area of the region enclosed by the inner loop of the curve is 72π square units.

The area of the part of the plane 5x + 3y + z = 15 that lies in the first octant is 15x^3/6 + 45x^2y/2.

Area is a measure of the size of a surface or the amount of space it takes up. It can be measured in square units such as square feet, square meters, or acres. Area is used to describe the size of a two-dimensional object or shape, and is often used when discussing the size of a plot of land, a room, or other geographical area.

The first octant is defined as the area in the three-dimensional Cartesian coordinate system where all the coordinates are positive. In this case, the equation 5x + 3y + z = 15 can be rearranged to solve for z: z = 15 - 5x - 3y. This new equation can then be used to find the area of the plane that lies in the first octant by integrating the equation over the area of the octant.

To solve for the area, we must first find the boundaries of the octant. Since all coordinates must be positive, the boundaries of the octant are x = 0, y = 0, and z = 0. The area of the plane that lies in the first octant is then computed using the triple integral:

Area = ∫∫∫ 0 0 0 15-5x-3y dzdydx

= ∫∫ 0 0 (15x + 45y)dydx

= ∫ 0 (15x^2/2 + 45xy)dx

= 15x^3/6 + 45x^2y/2

A standard deck of playing cards contains 13 unique ranks, each with 4 distinct suits. Since we are interested in only pairs from ranks 2 to 10, we shall define A be the collection of the 9 relevant ranks and B be the collection of the 4 ranks (ace, jack, queen, king) where pairs are not a consideration. Collection C is the union of A and B, which contains all 13 ranks.

When computing probabilities we need to select the ranks(s) from a collection and then choose a number of suits (cards). When ranks are chosen from either A or B they are also chosen from C. This is important since we might choose twice from the same collection. For example, we might choose a rank from A for a pair (9 choose 1) and later choose 3 ranks from C for singletons (12 choose 3).

To hopefully make understanding the logic easier, I have first chosen the ranks either from A, B, or C, and immediately following I have chosen the number of cards, which is always choosing from 4 suits. I have inserted a dot between different card selections.

We begin by computing the number of combinations with exactly 2, 3, and 4 of a kind from A. The singletons come from C.

N1=∑k=24(91)(4k)⋅(125−k)(41)5−k=760,320+38,016+432=798,768

We add the case of either two pairs from A or a pair from each of A and B. The singleton comes from C.

N2=[(92)+(91)(41)](42)2⋅(111)(41)=114,048

We add the case of a pair from A and 3 of a kind from C.

N3=(91)(42)⋅(121)(43)=2,592

Finally, we add the case of 3 of a kind from A and a pair from B. Note that the case of both 3 of a kind and a pair from A is the same as the case of both a pair and 3 of a kind from A, which has already been included.

Option (c) is correct.

Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods. It is the interest on interest, and it is the mechanism that causes an investment to grow at an exponential rate.

To calculate the amount of money you will have in the investment plan after 18 years, we can use the formula for compound interest:

A = P(1 + r)^n

Where:

A is the final amount (the future value)

P is the principal, or the initial deposit, in this case $300

r is the annual interest rate, in this case 7% (expressed as 0.07)

n is the number of years, in this case 18

m is the number of times the interest is compounded per year. in this case 12 (monthly)

By using this formula, the final amount will be:

A = 300(1 + 0.07/12)^(12*18)

A = $129,218.51

To compare this amount to the total deposits made over the time period, we can calculate the total amount of money deposited by multiplying the deposit amount ($300) by the number of deposits made per month (12) by the number of years (18).

Total deposit = 3001218 = $64,800

Given the following P(A) = 0.3, P(B) = 0.2, P(A) and P(B) 0.06. So, A and B are independent. This can be solved using probability concept.

The word "probability" derives from the Latin word "probitatem," which means "credibility, likelihood," from the noun probabilis in the 14th century (see probable). The phrase was first used in a mathematical meaning in 1718.

A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.

Given that,

P(A) = 0.3

P(B) = 0.2

P(A and B) = 0.06

Now, P(A and B) = P(A) × P(B)

Then, by dividing this difference by the rate of submergence, the owner can calculate the number of years it will take before it is necessary to take action to protect the pier from flooding. In this case, the answer is 40 years.

Answer:

x (number of games) = 8

Step-by-step explanation:

We want these two to be equal, which means we want:

4.50x + 5 = 4.75x + 3

We will minus 4.50x and 3 from both sides, giving us:

2 = .25x

Then, multiply by 4 to get a whole number of x, which gives us:

x = 8

Now, we will check our answer. We have:

4.50 * 8 + 5 = 4.75 * 8 + 3

36 + 5 = 38 + 3

41 = 41

So this proves x = 8.

So, the amount of games where the price would be the same is 8, x = 8.
