Find the solutions of each equation on the interval [0,2pi) sin(3pi/2+ x)+sin(3pi/2 +x)= -2

Mathematics
1 answer:
user100 [1]2 years ago
3 0

Answer:

x=0

Step-by-step explanation:

You can combine the equation to get 2sin(3/2 +x) = -2

divide both sides by 2 and you get the equation equal to -1. sin is equal to -1 when the value inside is 3/2 so this is the answer.

A plane is flying within sight of the Gateway Arch in St. Louis, Missouri, at an elevation of 30,000 ft. The pilot would like to
Maurinko [17]

Answer:

X = 33,669.78 ft

Y = 15285.76 ft

Step-by-step explanation:

Given data:

let x be the distance btwn arch and plane

and y be the distance btwn  ground point  and arch y

we know that

cos\theta =  \frac{adjacent}{hypotaneous}

cos(27) = \frac{30,000}{x}

xcos27 = 30000

x = \frac{30000}{cos 27}

x = 33,669.78 ft

b) we knwo that

tan \theta  = \frac{opposite}{adjacent}

tan 27 = \frac{y}{30000}

y = tan(27) (30000)

y = 15285.76 ft

The difference of the squares of two positive consecutive even integers is 44 find the integers use the fact that if X represent
TiliK225 [7]

Answer:

The 2 integers are 10 and 12

Step-by-step explanation:

Translate it into english

"The difference (some subtraction) of the squares of two positive consecutive integers (x^2 and (x+2)^2) is (=) 44 (44)"

this means the following:

(x+2)^2-x^2=44

solve for x to find the smaller integer

first, expand

(x^2+4x+4)-x^2=44

x^2+4x+4-x^2=44

4x+4=44

4x=40

x=10\rightarrow x+2=10+2=12

The 2 integers are 10 and 12
