Answer:

distance of the rocket from the pine high school ≈ 344 miles

Step-by-step explanation:

The illustration forms a triangle with 2 right angle triangle in it. The western high school angle of elevation  is 41° and the pine high school angle of elevation is 23°. The distance between the 2 school is 512 miles .The distance of the rocket from the pine school is the adjacent side of one of the right angle triangle .

The full triangle has angle of 23°, 41° and the last angle will be 180 - 23 - 41 = 116°. The hypotenuse side of the right angle triangle representing the pine high school triangle can be solved using sine formula.

p/sin 41° = 512/sin 116°

p/0.65605902899 = 512/0.89879404629

cross multiply

0.89879404629 p = 335.902222843

divide both sides by 0.89879404629

p = 335.902222843 /0.89879404629

p = 373.725464949

p ≈ 373.70 miles

using cosine ratio the adjacent side of the triangle can be found.

cos 23° = adjacent/hypotenuse

cos 23° = adj/373.70

cross multiply

adjacent = 0.92050485345  × 373.70

adjacent = 343.992663735

distance of the rocket from the pine high school = 343.992663735

distance of the rocket from the pine high school ≈ 344 miles

(HELP PLEASEE) The area of a rectangular swimming pool is 2x^2+13x-7. Find the dimensions of the swimming pool.
bearhunter [10]

Answer:

length =

2x - 1

width =

x + 7

Step-by-step explanation:

here we go,

=》

2x {}^{2}  + 13x - 7

=》

2 {x}^{2}  + 14x - x - 7

=》

2x(x + 7) - 1(x + 7)

=》

(2x - 1)(x + 7)

here, we got

the dimensions as :-

(2x - 1) \:  \: and \:  \: (x + 7)

The following data are the distances between 20 retail stores and a large distribution center. The distances are in miles.
Free_Kalibri [48]

Answer:

1191.4 ; 34.5

Step-by-step explanation:

Given the data:

29; 37; 38; 40; 58; 67; 68; 69; 76; 86; 87; 95; 96; 96; 99; 106; 112; 127; 145; 150

The sample variance and standard deviation can be obtained thus :

Σ(X - m)² / (n - 1)

Where, m = mean of the sample

n = sample size

The standard deviation equals, sqrt(variance )

Using a calculator:

The variance, σ² ;

Mean = Σx / n = 1681 / 20 = 84.05

(x -m)^2

[(29-84.05)^2 + (37-84.05)^2 + (38-84.05)^2 + (40-84.05)^2 + (58-84.05)^2 + (67-84.05)^2 + (68-84.05)^2 + (69-84.05)^2 + (76-84.05)^2 + (86-84.05)^2 + (87-84.05)^2 + (95-84.05)^2 + (96-84.05)^2 + (96-84.05)^2 + (99-84.05)^2 + (106-84.05)^2 + (112-84.05)^2 + (127-84.05)^2 + (145-84.05)^2 + (150-84.05)^2] / 19

22636.95 / 19

= 1191.4184 = 1191.42

Standard deviation = sqrt( Variance)

Standard deviation = sqrt(1191.4184)

Standard deviation = 34.516929 = 34.52
