Answer:

a^2 + b^2 = c^2

Step-by-step explanation:

In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

a^2 + b^2 = c^2

a = side of right triangle

b = side of right triangle

c = hypotenuse

*can only be used for a RIGHT triangle*

8=-3x2+16  Subtract 8 from both sides

0=-3x2+8

Now, use the quadratic equation to solve for x

C. 1.6s

Step-by-step explanation:

The skateboarder is 8 feet from the bottom of the hill after 1.633 seconds.

Quadratic functions are polynomial functions consisting of variables and exponents and the degree of the variable is 2.

The general form of a quadratic function is f(x) = ax² + b x + c.

Given that,

Quadratic function which models a skateboarder’s distance, in feet, from the bottom of a hill x seconds after the skateboarder starts moving down the hill is,

d = –3x² + 16

We have to calculate after how many seconds is the skateboarder 8 ft from the bottom of the hill.

d = 8 feet. Substitute it.

–3x² + 16 = 8

–3x² = 8 - 16

3x² = 8

x² = 8/3

x = √(8/3) seconds

  ≈ 1.633 seconds

Hence the time is approximately 1.633 seconds.

Answer:

In 17 years time, the initial population of 3400, and growing at a rate of 5% will be ≈ 7792

Step-by-step explanation:

Here we have that the formula for population presented as follows;

[tex]A = P(1+r)^t[/tex]

Where:

A = Population after growth

P = Original population = 3400

r = 5% = 0.05

t = Time = 17 years

Population growing at a rate of 5% is thus given by the plugging in the above values into the population growth formula thus;

[tex]A = 3400 \times (1+0.05)^{17} = 7792.86[/tex]

Since we are presenting data relating to number of people, we round alwys down as the statistics should represent the number of whole people on ground.

Therefore, in 17 years time, the initial population of 3400, and growing at a rate of 5% will be ≈ 7792.

Answer:

Step-by-step explanation:

The growth rate is exponential. We would apply the formula for exponential growth which is expressed as

y = b(1 + r)^ t

Where

y represents the population after t years.

t represents the number of years.

b represents the initial population.

r represents rate of growth.

From the information given,

b = 3400

r = 5% = 5/100 = 0.05

t = 17 years

Therefore

y = 3400(1 + 0.05)^17

y = 3400(1.05)^17

y = 3400 × 2.2920183178

y = 7800 to the nearest thousand

Answer:

k = 22.5

xy= 22.5

Step-by-step explanation:

Answer:

Let's denote:

P(discount on 15 holidays) = P(A) = 0.87

P(discount on 100 weekends) = P(B) = 0.38

P(discount on 250 weekdays) = P(C) = 0.17

=> The probability of a discount of more than 10% for the randomly chosen day: P = P(A) x 15/360 + P(B) x 100/360 + P(C) x 250/360

          = 0.87 x 15/360 + 0.38 x 100/360 + 0.17 x 250/360

          = 0.26

Given she bought a machine with a discount of more than 10%, the probability that it was a weekend would be:

P  = 100/(100 + 250 + 15) = 0.27

Hope this helps!

:)

Answer:

1. 0.256

2. 0.406

Step-by-step explanation:

Total days:

15 + 100 + 250 = 365

P(more than 10% discount)

= (0.87×15/365) + (0.38×100/365) +(0.18×250/365)

= 1871/7300

0.2563013699

P(weekend/more than 10% discount)

= (0.38×100/365) ÷ (1871/7300)

= 760/1871

Answer:

The surface area of the triangular prism is 24 mi².

Step-by-step explanation:

A surface area is the sum of the areas of all faces on a 3D shape.

A triangular prism has 5 faces consisting of three rectangular sides and two triangular faces.

To find the surface area of the rectangular sides, you multiply the length by the height.

5x1=5

4x1=4

3x1=3

5+4+3=12

the surface area of the rectangular sides is 12 mi²

To find the surface area of the triangular faces, you can use the formula, A=1/2bh, where A is the surface area, b is the base, and h is the height.

A=1/2 · 3(base) · 4(height)

Since there are two triangular sides you multiply this by 2, which cancels out the 1/2 since 1/2 x 2 = 1.

A = 3 · 4

A = 12

the surface area of the triangular faces is 12 mi²

Add up the total surface area of the rectangular sides and triangular faces.

12 + 12 = 24

Answer:12.33333333333

Step-by-step explanation:

8x - 2 = 14x - 76

74 = 6x

12.333 = x

The required value of the x is 13 in the measures of the angle.

Given that,
Line A and B are parallel lines and intersect by a transversal line.

A line can be defined by the shortest distance between two points is called a line.

Parallel lines are defined as the line on which the corresponding points are equidistant throughout the line

Here,
If a pair of parallel lines intersect by the transversal line then their corresponding angles are equal in measure,
Thus,
8x + 2 = 14x - 76
6x = 78
x = 78 / 6
x = 13

Thus, the required value of the x is 13 in the measures of the angle.

Answer:

Total length of the first swing=64 m

Step-by-step explanation:

The total length of all four swings can be expressed as; Total length of all 4 swings=Length of first swing+length of second swing+length of third swing+length of fourth swing

where;

Total length of all 4 swings=175 m

Length of first swing=x

Length of second swing=75% of length of first swing=(75/100)×x=0.75 x

Length of third swing=75% of length of second swing

Length of third swing=(75/100)×0.75 x=0.5625 x

Length of fourth swing=75% of length of third swing

Length of fourth swing=(75/100)×0.5625 x=0.421875 x

replacing;

Total length of all 4 swings

175=x+0.75 x+0.5625 x+0.421875 x

2.734375 x=175

x=175/2.734375

The solution to the equation is x = 7, -1.

The equation of the form ax² + bx +c is known as a quadratic equation.

The given equation is 2.1/x + 1 (4/5) =(3/10)x.

Simplify the equation as follows:

2.1/x + 1 (4/5) =(3/10)x

2.1/x + 9/5 = (3/10)x

2.1 + (9/5)x = (3/10)x²

21 + 18x = 3x²

3x² - 18x -21 =0

3x² - 21x + 3x -21 =0

3x(x - 7) + 3(x - 7) =0

(x - 7)(3x + 3) =0

x - 7 =0 or 3x + 3 =0

x = 7 or x = -1

Hence, the solution to the equation is x = 7, -1.

Answer:

The perimeter of triangle is 30ft.

Step-by-step explanation:

First you have to find the value of a using Pythogoras Theorem, a² + b² = c² where a and b is the sides and c is the hypotenuse :

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

[tex] {a}^{2} = {c}^{2} - {b}^{2} [/tex]

[tex]a = \sqrt{ {c}^{2} - {b}^{2} } [/tex]

Let b = 12,

Let c = 13,

[tex]a = \sqrt{ {13}^{2} - 12 {?}^{2} } [/tex]

[tex]a = \sqrt{25} [/tex]

[tex]a = 5feet[/tex]

Next you have to find the perimeter of triangle by adding all the sides together :

[tex]perimeter = 5 + 12 + 13[/tex]

[tex]perimeter = 30feet[/tex]
