Answer:

The bushes will be located 6 meters apart from each other.

Step-by-step explanation:

Given that at a walking path 78 mile long Colleen planted 14 bushes the same distance apart along the path, to determine how far away are the 1st 2 bushes along the path, the following calculation must be performed:

78/13 = X

6 = X

Thus, since the first bush is at meter 0, the remaining 13 bushes will be located 6 meters apart.

We can simplify the expression using trigonometric identities.

First, we can use the double angle formula for sine to write sin(2x) = 2sin(x)cos(x).

Next, we can use the double angle formula for cosine to write cos(2x) = cos^2(x) - sin^2(x) = 1 - 2sin^2(x). Rearranging this equation gives 2sin^2(x) - 2cos^2(x) = -cos(2x) + 1.

Substituting these identities into the original expression gives:

tan(x-1) ( sin2x-2cos2x) = tan(x-1) [2sin(x)cos(x) - 2(1 - 2sin^2(x))]

= 2tan(x-1)sin(x)cos(x) - 2tan(x-1) + 4tan(x-1)sin^2(x)

We can use the identity tan(x) = sin(x)/cos(x) to simplify this expression further:

2tan(x-1)sin(x)cos(x) - 2tan(x-1) + 4tan(x-1)sin^2(x)

= 2sin(x)cos(x)/(cos(x-1)) - 2sin(x)/(cos(x-1)) + 4sin^2(x)/(cos(x-1))

Multiplying both sides of the equation by cos(x-1) gives:

2sin(x)cos(x) - 2sin(x) + 4sin^2(x)cos(x-1) = 2(1-2sin(x)cos(x))

Expanding the left-hand side of the equation gives:

2sin(x)cos(x) - 2sin(x) + 4sin^2(x)cos(x) - 4sin^2(x) = 2 - 4sin(x)cos(x)

Simplifying this equation gives:

4sin^2(x) - 2sin(x) - 2 = 0

This is a quadratic equation in sin(x), which can be solved using the quadratic formula.

Step-by-step explanation:

The height of the cliff diver after 1.25 seconds is 35 feet.  

The concept used is evaluating a function at a given input or value. In this case, we are evaluating the height function H(t) at t = 1.25 to find the height of the cliff diver after 1.25 seconds. The formula for the height function is given as H(t) = -16t^2 + 32t + 20.

Here we have

A cliff diver's height (in feet) after t seconds is given by the model

H(t)=-16t² +32t +20  

Given time t = 1.25 seconds

To find the height after 1.25 seconds, we simply need to evaluate H(1.25) using the given formula:

H(1.25) = -16(1.25)² + 32(1.25) + 20

On Simplifying the expression we get:

H(1.25) = -16(1.5625) + 40 + 20

H(1.25) = -25 + 60

H(1.25) = 35

Therefore,

The height of the cliff diver after 1.25 seconds is 35 feet.

For this case the inital amount was $75.00

We can find the individual costs like this:

C1= 4$ * 3= 12.00

C2= 4$* 4= 16.00

C3 = 21.00$

Then total cost= 12+16+21= 49$

please, this is so easy !

so, please, burn this into your brain forever : the sum of all angles in a triangle is always (really, always) 180°.

so,

180 = 25 + 100 + A

A = 55°

ΔABC has: ∠CAB + ∠ABC + ∠ACB = 180°

so:  ∠CAB = 180° - ∠ABC - ∠ACB = 180° - 100° - 25° = 55°

ANSWER: ∠CAB = 55°

Step-by-step explanation:yes

There is no whole number by which you can multiply or divide 16087 to make it a perfect square.

To determine by which number you should multiply or divide 16087 to make it a perfect square, we can analyze its prime factorization. The prime factorization of 16087 is 13 × 1237.

In order to make 16087 a perfect square, we need each prime factor to have an even exponent. However, when we examine the prime factors of 16087, we find that both 13 and 1237 have an exponent of 1.

To make the exponents even, we need to multiply or divide 16087 by additional prime factors and their respective exponents. However, since 16087 is a product of two prime numbers (13 and 1237), we cannot introduce any additional prime factors to make the exponents even.

A perfect square is a number that can be expressed as the product of two equal factors. In the case of 16087, it cannot be transformed into a perfect square by multiplying or dividing by any whole number. The prime factors 13 and 1237 remain with an exponent of 1 each, indicating that there is no integer that can be applied to make them equal and convert 16087 into a perfect square.

Therefore, there is no whole number by which you can multiply or divide 16087 to make it a perfect square.

Step-by-step explanation:

Answer:

a)

P ( R = 20 million ) = 0.00000095367

P ( R = 0 million )  i.e. not winning = 0.99999904633

b)  P ( L ) = ( 1 - p )^l  * p

C)The casino offer the game because  the expected revenue exceeds the winning

Step-by-step explanation:

P( winning ) = P ( getting 20heads in a row ) = 0.5^20 = 0.00000095367

a)  PMF of R

P ( R = 20 million ) = 0.00000095367

P ( R = 0 million )  i.e. not winning = 0.99999904633

b) what is the PMF of L

L = number of loosing clients before winning

P( L = 0 ) = P   i.e. if first contestant wins, if the second contestant win, L=1 repeat same process continuously

P ( L = 2 ) = ( 1 - p)^2 p

Hence the PMF of L  

P ( L ) = ( 1 - p )^l  * p     where p = 0.5^20

C) The casino offer the game because  the expected revenue exceeds the winning

we can prove this using  the relation below

E( L ) =  ( 1 - P ) / 1 - ( 1 - P )

        = 1 / P - 1

where  p = 0.00000095367  ( probability of winning )

Hence E ( L ) = 1048575

hence expected revenue before someone wins

= (1048575 + 1 ) * 20 = $20,971,520
