If Kira is a lovable dog who is full of energy. Her owner thought it would be fun to train her by throwing a frisbee for her to catch. The number of  seconds  it will take for the frisbee to hit the ground is: 6.2 seconds.

Given:

0.145t² + 0.019t + 5.5 = 0

Using almighty formula or quadratic formula

t=-b±√b²-4ac/2a

Where:

b²=19²

a=145

c=5500

Let plug in the formula

t=-19±√19²- 4(-145) (5500)/2(-145)

t=-19±√361+(3,190,000)/-290

t=-19±√3,190,361/-290

t=-19±1,786.158/-290

Hence,

-19-1,786.158/-290; -19+1,786.158/-290

t=6.2; 6.09

Therefore If Kira is a lovable dog who is full of energy. Her owner thought it would be fun to train her by throwing a frisbee for her to catch. The number of  seconds  it will take for the frisbee to hit the ground is: 6.2 seconds.

Given that

To find

So, according to the question

we have,

         (0,40) and (15,70)

We have to find the equation of line

So, we know that

               y = mx + c, ---------------(1)

From graph,

           c = 40 and

           m = slope (we have to find it)

We kwon the slope of any two point

      m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Where,

        x₁ = 0 , and y₁ = 40

        x₂ = 0 , and y₂ = 40        

So,

      m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

      m = [tex]\frac{70-40}{15-0}[/tex]

      m = [tex]\frac{30}{15}[/tex]

      m = 2

Now putting the all values in equation (1)

We will get,

In the given sequence, the next term is obtained by multiplying the next term by (-1), hence it is a geometric sequence with r = 1. The next two terms are 3, -3.

Arithmetic sequence.

In a arithmetic sequence, the next term = the previous term + common difference. Or mathematically:

a(n) = a(n-1) + d

or d = a(n) - a(n-1) for all n

Where d = common difference.

Geometric sequence.

In a geometric sequence,  the next term = the previous term x common ratio. Or mathematically:

a(n) = a(n-1) . r

or r = a(n)/a(n-1) for all n

Where r = common ratio

The sequence given:

           3,-3,3,-3, . . . . .

In this sequence:

a(1) = 3

a(2) = -3

a(3) = 3

a(4) = -3

The next two terms means a(5) and a(6). We already have a(4) = -3. Hence,

a(5) = a(4) . r = -3. (-1) = 3

a(6) = a(5) . r = 3. (-1) = -3

Answer:

a₁ = 15

Step-by-step explanation:

the sum to n terms of an arithmetic sequence is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

given S₁₄ = - 63 , then

[tex]\frac{14}{2}[/tex] [ 2a₁ + 13d ] = - 63

7(2a₁ + 13d) = - 63 ( divide both sides by 7 )

2a₁ + 13d = - 9 → (1)

the nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

given a₁₄ = - 24 , then

a₁ + 13d = - 24 → (2)

subtract (2) from (1) term by term to eliminate d

a₁ + 0 = - 9 - (- 24)

a₁ = - 9 + 24 = 15

Main Answer:

The required value of PB is 21.

An equation is a mathematical statement with an equal symbol between two expressions that have equal values.

Given: If A-P-B and if AP=2x-9, AB=32, and PB=1.5x+6.

To find: Find PB.

According to the question,

AP + PB = AB

On putting the given values, we get,

(2x-9)+(1.5x+6) = 32

2x - 9 +1.5x + 6 = 32

3.5x - 3 = 32

3.5x = 32+3

3.5x= 35

x=10

Now, we will substitute the value of x=10 in the equation, we get,

PB= 1.5x+6

PB= 1.5 × 10 + 6

PB=15 + 6

PB=21

When measuring height, it is necessary to represent both the vertical position and the separation between the minimum and maximum place or location. The height of Kara's building is 186.6 ft.

In math, height can be defined as the vertical distance from the top to the base of the object. Height is the distance between an object's highest and lowest points.

The measurement of an object's height from the base to the top is known as the height. It is sometimes referred to as altitude in geometry. The vertical distance between the lowest and highest point is measured. In coordinate geometry, it is often the measurement along the y-axis of an object.

Mount Everest's summit serves as an illustration of height.

Ignoring the height of Kara,

h = 50 tan 75°

substituting the value of tan 75°, we get

= 50 × 3.7321

Height of building = 186.6 ft.

What is an angle in math?

The bearing of B from D is angle ADB, which is

∠ADB = arctan(30/45) ≈ 33.7°

The bearing of D from B is that angle plus 180°, so is

180° +33.7° = 213.7°

We use angle ADB because the reference direction for bearings is North.

The tangent of an angle (ADB) is the ratio of its opposite side (AB) to its adjacent side (AD).

This sequence follows the rules of Arithmetic Progression

Arithmetic Progression is an example of mathematical sequences. In this sequence, the next term is generated by adding the previous term to a fixed number which is called 'Common Difference'. This is generally represented by 'd'. It is calculated by subtracting any two consecutive terms in the sequence.

We can generally find out any term of the given statement. The  [tex]n^{th}[/tex] term of a sequence is calculated by adding the previous term to the common difference. The formula to calculate the [tex]n^{th}[/tex] term of an Arithmetic Progression is :

                     =>  [tex]a_{n} = a_{n-1} + d[/tex]

Here, n = No. of term, [tex]a_{n-1}[/tex] = previous term, and d = common difference

In the given sequence, 5,22,39,56......

Each term is separated by a common difference 'd'

Calculating d = a2-a1   => d = 22-5 => d = 17

Every term has a common difference of 17 so this is an Arithmetic Sequence
