pls answer! Dylan spots an airplane on radar that is currently approaching in a straight line, and
that will fly directly overhead. The plane maintains a constant altitude of 6400 feet.
Dylan initially measures an angle of elevation of 16° to the plane at point A. At some
later time, he measures an angle of elevation of 36° to the plane at point B. Find the
distance the plane traveled from point A to point B. Round your answer to the
nearest foot if necessary.

The modified boxplot created for the distribution is boxplot E

Given the values :

25, 34, 46, 37, 33, 42, 40, 37, 34, 49, 73, 46, 45, 45, 5

The outliers in the values are : 5 and 73

Hence, the modified values are :

25, 34, 46, 37, 33, 42, 40, 37, 34, 49 , 46, 45, 45

Using a boxplot maker or excel, we could use the modified data to create a boxplot with the following properties as obtained from the boxplot shown below :

Median value = 40

Minimum = 25

Maximum =  49

First quartile = 34

Third quartile = 45.5

The modified boxplot has no outlier and it corresponds with the boxplot in option E

Answer:

Step-by-step explanation:

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

( f(3 + h) - f(3) ) / h

f(3 + h) = 2(3 + h)^2 + 1)

f(3 + h) = 2(9 + 6h + h^2) + 1

f(3 + h) = 18 + 12h + 2h^2 + 1

f(3 + h) = 19 + 12h +2h^2

f(3) = 2*(3^2) + 1

f(3) = 2(9) + 1

f(3) = 19

f(3 + h) - f(3) = 2h + 2h^2  The 19s cancel out

f(3 + h) - f(3) = 2h(1 +  h^2)

(  f(3 + h) + f(3)  ) / h  =  2h ( 1 + h^2) / h = 2 ( 1 + h^2)

The equation of the above linear function

From the table, we have:

[tex](x_1,y_1) = (1,1)[/tex]

[tex](x_2,y_2) = (2,4)[/tex]

Calculate slope (m)

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

[tex]m = \frac{4 -1}{2 -1}[/tex]

[tex]m = \frac{3}{1}[/tex]

[tex]m =3[/tex]

The equation is:

[tex]y = m(x - x_1) + y_1[/tex]

So, we have:

[tex]y = 3(x - 1) + 1[/tex]

[tex]y = 3x - 3 + 1[/tex]

[tex]y = 3x - 2[/tex]

Answer:

the last answer

Step-by-step explanation:

S(x) = 4pix^2

replace S(x) with y => y = 4pix^2

switch x and y variables => x=4piy^2

solve for y

That eliminates the first 2 answers because S^-1(x) is incorrect, which leaves the last two answers.

Step-by-step explanation:

If the centre of a circle is (a, b) and radius r, then the equation of the circle is :

[tex](x - x)^2 + (y-b)^2 = r^2[/tex]

First we will find the centre, (a , b):

[tex]a = \frac{3+(-1)}{2} = \frac{2}{2} = 1\\\\b = \frac{-2 + 4}{2} = \frac{2}{2} = 1[/tex]

Find radius:

[tex]Radius, r = \frac{Diameter}{2}[/tex]

Diameter is the distance between (-1, 4) and (3, -2)

[tex]diameter = \sqrt{(x_2 - x_1)^2 +(y_2-y_1)^2} \\\\[/tex]

             [tex]= \sqrt{(3-(-1)^2 + (-2-4)^2} \\\\=\sqrt{16 + 36}\\\\=\sqrt{52}\\\\=\sqrt{4 \times 13}\\\\=2\sqrt{13} \ units[/tex]

Therefore , [tex]r = \frac{2 \times \sqrt{13} }{2} = \sqrt{13} \ units[/tex]

Equation of the circle is :  

                                 [tex](x - 1)^2 +(y-1)^2 = 13[/tex]

Answer:

  (x +yi)²

Step-by-step explanation:

Comparing the given expression to the square of a binomial, we can determine the given expression to be a square.

  (a +b)² = a² +2ab +b²

Here, we have a=x and b=yi. Then the factorization is ...

  x² +2xyi +(yi)² = (x +yi)²

Answer:

The 7th number in the sequence is [tex]\frac{125}{8}[/tex]

Step-by-step explanation:

Geometric sequence:

In a geometric sequence, the quotient between consecutive terms is always the same, called common ratio.

The nth term of a geometric sequence is given by:

[tex]A_n = A(0)r^{n-1}[/tex]

In which A(0) is the first term and r is the common ratio.

1000,-500,250,-125

This means that [tex]A(0) = 1000, r = -\frac{500}{1000} = -\frac{1}{2}[/tex]

So

[tex]A_n = A(0)r^{n-1}[/tex]

[tex]A_n = 1000(-\frac{1}{2})^{n-1}[/tex]

What is the 7th number in the sequence?

This is [tex]A_7[/tex]. So

[tex]A_7 = 1000(-\frac{1}{2})^{7-1} = \frac{1000}{64} = \frac{125}{8}[/tex]

The 7th number in the sequence is [tex]\frac{125}{8}[/tex]

Answer:

  60 gallons

Step-by-step explanation:

The area of the trapezoid-shaped wall is given by ...

  A = 1/2(b1 +b2)h

where b1 and b2 are the lengths of the parallel sides, and h is the perpendicular distance between them.

The area of the wall is ...

  A = (1/2)(5 ft + 15 ft)(6 ft) = 60 ft²

If it takes 1 gallon to cover 1 square foot, then it will take 60 gallons to cover 60 square feet.

Isha needs 60 gallons of paint.

Answer:

Isha needs 60 gallons of paints to the wall.

Step-by-step explanation:

The area of trapezoid shaped like wall is given by :-

Area of trapezoid = 1/2 × ( Base ¹ + Base ² ) × H

Where,

B ¹ and B ² are the length of bases and H is the perpendicular distance between them.

Area of wall = 1/2 × ( Base¹ + Base²) × Height

Where, according to question we have

substitute the values

Area = 1/2 × ( 5 ft + 15 ft ) × 6 ft

add the values of Base¹ and Base ²

Area = 1/2 × 20 ft × 6 ft

multiply

Area = 1 / 2 × 120 ft ²

divide

Area = 120 ft ² / 2 = 60 ft ²

It takes 1 gallon to cover 1 ft ². ... ( given)

So, For covering 60 ft ² it takes 60 gallons .

check

( 1 × 60 ) gallon = 60 ft ²

60 gallon = 60 ft²

Step-by-step explanation:

Answer:

y = 250x + 1000

Step-by-step explanation:

we know, it is a linear function.

so, y = ax + c

we have multiple data points all on the line.

(4,2000)

2000 = a×4 + c, => c = 2000 - a×4

(7,2750)

2750 = a×7 + c

=> 2750 = a×7 + 2000 - a×4 = a×3 + 2000

=> 750 = a×3

=> a = 250

=> c = 2000 - 250×4 = 2000-1000 = 1000

Determine AC

Since A, B and C are collinear, then:

[tex]AC = AB + BC[/tex]

So, we have:

Answer:

answers below.  Let me know if anything didn't make sense.  You definitely need to make sure you understand so you can put it into your own words.  

Step-by-step explanation:

2a:  The fraction bar for 4/5 would be more full.  if you cannot picture ityou may just have to draw it.  use a ruler and draw two equal length "bars" then divide one into fifths and the other into sevenths, then fill in the appropriate amount.

2b:  4/5 > 4/7

2c:  The idea is that as the denominator gets larger, those 4 pieces take up less and less space.  Try thinking what happens with 4/1, 4/2, 4/3, 4/4, 4/5, 4/6 and 4/7  It ight be easier to envision something like 1/2 and 1/4.  Two 1/4s would make 1/2, so 1/4 is less than 1/2.

3a:  You could try thinking in percents or decimals.  1/2 is obviously 50% then 4/7 is 4 times 1/7, and 1/7 is about 14%, so 14*4= 56%.  Or you could compare more directly like saying 1/2 is 50% and 3.5/7 would be 50%, so 4/7 is bigger. There are a lot of ways to think about it.  

3b:  the easyness is shown in my second idea in 3a.  it's super easy to cut a number in half.  it will either be a whole number or a number with .5 at the end.  then you can tell if your other fraction is bigger or smaller than 1/2

Step-by-step explanation:

But we know that

[tex]\cos 90 = \cos 270 = \sin 180 = 0[/tex]

and

[tex]\sin 30 = \dfrac{\sqrt{3}}{2} \:\:\text{and}\:\: \sec 45 = \sqrt{2}[/tex]
