Answer:

Yup P is the right one having 62.26%

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

We can set it up as

P = 33/53

Q = 20/48

R = 54/90

S = 44/83

This is because we are calculating the percent of yellow birds in the total amt. of birds in a specified park.

Now we calculate =>

P = 33/53 = around 0.62

Q = 20/48 = around 0.416

R = 54/90 = 0.6

S = 44/83 = around 0.53

We find that Park P has the greatest percentage and -->

Thus, Park P is our answer and yes, you are correct.

Answer:

The vertex is ( -1/2, 3/4)

Step-by-step explanation:

f(x)=x^2+x+1

The vertex form is

y = a( x-h) ^2 +k where (h,k) is the vertex

Rewriting the function by completing the square

Taking the coefficient of x and dividing by 2 and squaring it

(1/2) ^2 = 1/4

Adding it and subtracting it

f(x) = x^2 + x + 1/4 -1/4 +1

    = ( x^2+ x +1/4) + 3/4

   = ( x+ 1/2) ^2 + 3/4

 = ( x- -1/2) ^2 + 3/4

The vertex is ( -1/2, 3/4)

Answer:

B) (x^2-2x)/(2x+6)

Step-by-step explanation:

When dividing fractions, it's just like multiplying the reciprocal of the second fraction : x/y divided by z/w = x/y * w/z.

We use that and we get (x-2)/(x+3) * x/2. we simplify and get x(x-2)/2(x+3). So Our answer is B

Answer:

4(A)=36

Step-by-step explanation:

An equation is said to be unique if the equation has a valid solution. Several unique equations that equal 36 can be taken from the given values. Some of these equations are:

[tex]4G + M + 2B = 36[/tex]

[tex]10F- N -D = 36[/tex]

[tex]10D + G =36[/tex]

[tex]4M - E = 36[/tex]

[tex]4L = 36[/tex]

[tex]9E = 36[/tex]

To get a unique equation, we ensure that the right-hand side of the equation equals the left-hand side. There are no quick solution to this; so, we make use of trial by error method.

After several trials, some possible equations with three variables are:

[tex]4G + M + 2B = 36[/tex] because  [tex]4 \times 6 + 10 + 2 \times 1 = 36[/tex]

[tex]10F- N -D = 36[/tex] because [tex]10 \times 5- 11 -3 = 36[/tex]

Some possible equations with two variables are:

[tex]10D + G =36[/tex] because [tex]10 \times 3 + 6 =36[/tex]

[tex]4M - E = 36[/tex] because [tex]4 \times 10 - 4 = 36[/tex]

Some possible equations with two variables are:

[tex]4L = 36[/tex] because [tex]4 \times 9 = 36[/tex]

[tex]9E = 36[/tex] because [tex]9 \times 4 = 36[/tex]

The following are some unique equations from the given values:

[tex]4G + M + 2B = 36[/tex]

[tex]10F- N -D = 36[/tex]

[tex]10D + G =36[/tex]

[tex]4M - E = 36[/tex]

[tex]4L = 36[/tex]

[tex]9E = 36[/tex]

Answer:

sorry im suppppper late but it is B

Step-by-step explanation:

Answer:

Step-by-step explanation:

The vertex can be located most easily by completing the square of

f(x) = -X^2 - 2x - 1 (which is equivalent to -(x^2 + 2x + 1).  The latter expression can be rewritten as -(x + 1)^2, which indicates that the x-coordinate of the vertex is -1.  The corresponding y-value is 0.  Vertex is at (-1, 0).

The function is increasing for x < -1 and decreasing for x > -1.

The domain of the function is "all real numbers."

The range is (-infinity, 0)

Answer:

A

Step-by-step explanation:

When you divide a term with an exponent by the same term with a different exponent, simply subtract the exponents.

Applying the quotient rule of exponents, 6 to the 9th power divided by 6 to the 3rd power is calculated as: A. [tex]6^6[/tex].

To simplify the expression [tex]6^9[/tex] / 6³, we can use the quotient rule of exponents. Here's the step-by-step calculation:

Write both terms with the same base, 6:

[tex]6^9[/tex] / 6³

Apply the quotient rule of exponents, subtracting the exponent in the denominator from the exponent in the numerator:

[tex]6^{(9-3)}[/tex]

Simplify the exponent:

[tex]6^6[/tex]

Therefore, 6 to the 9th power divided by 6 to the 3rd power simplifies to: A. [tex]6^6[/tex].

Answer:

[tex]\sum^\infty_{n=0} -5 (\frac{x+2}{2})^n[/tex]

Step-by-step explanation:

Rn(x) →0

f(x) = 10/x

a = -2

Taylor series for the function f at the number a is:

[tex]f(x) = \sum^\infty_{n=0} \frac{f^{(n)}(a)}{n!} (x - a)^n[/tex]

[tex]f(x) = f(a) + \frac{f'(a)}{1!}(x-a)+\frac{f"(a)}{2!} (x-a)^2 + ...[/tex] ............ equation (1)

Now we will find the function f and all derivatives of the function f at a = -2

f(x) = 10/x            f(-2) = 10/-2

f'(x) = -10/x²         f'(-2) = -10/(-2)²

f"(x) = -10.2/x³      f"(-2) = -10.2/(-2)³

f"'(x) = -10.2.3/x⁴     f'"(-2) = -10.2.3/(-2)⁴

f""(x) = -10.2.3.4/x⁵    f""(-2) = -10.2.3.4/(-2)⁵

∴ The Taylor series for the function f at a = -4 means that we substitute the value of each function into equation (1)

So, we get [tex]\sum^\infty_{n=0} - \frac{10(x+2)^n}{2^{n+1}}[/tex] Or [tex]\sum^\infty_{n=0} -5 (\frac{x+2}{2})^n[/tex]

Taylor series  is a power series that gives the expansion of a function f (x) in the neighborhood of a point.

Taylor series is,   [tex]f(x)=f(a)+\frac{f'(a)}{1!}(x-a)+\frac{f''(a)}{2!}(x-a)^{2}+........[/tex]

[tex]f(x)=\sum_{n=0}^{\infty }-\frac{10(x+2)^{n}}{2^{n+1}}[/tex]

Here,  f(x) = 1/x  and a = -2

Now find derivative,

 f(x) = 10/x            f(-2) = 10/-2

f'(x) = -10/x²         f'(-2) = -10/(-2)²

f"(x) = 10.2/x³      f"(-2) = 10.2/(-2)³

f"'(x) = -10.2.3/x⁴     f'"(-2) = -10.2.3/(-2)⁴

Substituting above values in Taylor series expansion.

We get,   [tex]f(x)=\sum_{n=0}^{\infty }-\frac{10(x+2)^{n}}{2^{n+1}}[/tex]

Answer:

49.8 nautical miles

Step-by-step explanation:

Recall that speed = distance/time

Time = 2hours

Speed = 12knots and 16 knots respectively

D = speed×time

D1 = 12×2 = 24

D2 = 16×2 = 32

Using the 'cosine rule' we have:

a^2 = b^2+c^2-2bc cos Θ

Where a =?

b =24

c = 32

Θ = 125°

a² = 24² + 32² - 2(24)(32)cos125°

a^2 = 576+1024 - 1536cos125°

a² = 1600 - 1536(-0.57357)

a² = 1600+881.0134

a² = 2481.0134

Then, a² = 2481.013406

a =√2481.013406

Hence, a = 49.8 nautical miles

In this exercise we must use the knowledge about triangles to calculate the distance that a ship will travel, in this way we find that:

49.8 nautical miles

First, remember the formula for distance, which is:

[tex]Speed = distance/time[/tex]

And knowing that the data reported in the exercise are:

So putting the values ​​informed in the distance formula, we have:

[tex]D = speed*time\\D_1 = 12*2 = 24\\D_2 = 16*2 = 32[/tex]

Using the 'cosine rule' we have:

[tex]a^2 = b^2+c^2-2bc cos \theta[/tex]

Find the a, will have:

[tex]b =24 \ \ \ c = 32 \ \ \ \theta = 125\\a^2 = 24^2 + 32^2 - 2(24)(32)cos125\\a^2 = 576+1024 - 1536cos125\\a^2 = 1600 - 1536(-0.57357)\\a^2 = 1600+881.0134\\a^2 = 2481.0134\\a=49.8[/tex]

Answer:

Step-by-step explanation:

We would apply the future value which is expressed as

FV = C × [{(1 + r)^n - 1}/r]

Where

C represents the yearly payments of the young professional.

FV represents the amount of money

in your account at the end of 40 years.

r represents the annual rate.

n represents number of years or period.

From the information given,

r = 4% = 4/100 = 0.04

C = $76000

n = 40 years

Therefore,

FV = 76000 × [{(1 + 0.04)^40 - 1}/0.04]

FV = 76000 × [{4.8 - 1}/0.04]

FV = 76000 × 95

Hey there! :)

Answer:

Point V.

Step-by-step explanation:

Given the coordinates of T at (-6.5, 1), U represents T before any reflections. (Helps to visualize this better)

Reflecting across the x-axis results in the sign of the y-coordinate changed. Point T after this reflection becomes (-6.5, -1).

Finally, reflecting across the y-axis will change the sign for the x-coordinate.

(-6.5, -1) becomes (6.5, 1). This is represented by point V.

Answer: Twice.

The measure of the central angle is two times the measure of the circumference angle.

Answer:

The central angle theorem states that the central angle from two chosen poinfs A and B on the circle is always twice the inscribed angle from two points.

Please see the attached picture

Draw a line from the point O to point P

OP = OA = OB = radius

<APO = a , <BPO = b

<PAO = a , < PBO = b

( isosceles triangle)

<POA = 180 - 2a

<POB = 180 - 2b

All Angles at centre O must add up to 360°

< AOB = 360 - ( 180 - 2a ) - ( 180 - 2b )

<AOB = 2a + 2b

<AOB = 2 ( a + b )
