The angle of elevation from the top of a house to a jet flying 2 miles above the house is x radians. If d represents the horizon
alisha [4.7K]

Answer:

d = 2cot(x) or d = 2/tan(x)

Step-by-step explanation:

The vertical distance from the jet to the top of the house represents the opposite side to the 'x' angle, while the horizontal distance, d, represents the adjacent side. Since we do not know the hypotenuse, the tangent and cotangent functions are the preferable choices:

tan (x) = \frac{2}{d}\\d = \frac{2}{tan (x) }\\cot (x) = \frac{d}{2} \\d= 2cot(x)

Therefore, the distance 'd' can be expressed as d = 2cot(x) or d = 2/tan(x).

Need help real fast please help really need it
Vladimir79 [104]

Answer:

burrito price=$8

Taco Price=$6

Step-by-step explanation:

x=burrito price

y=taco price

3x+4y=48

solve for y

y= −3 /4 x+12

plug in

6x+2y=60

6x+2( −3 /4 x+12)=60

6x+2( −3 /4 x+12)=60

x=8

now plug in for x

3x+4y=48

3(8)+4y=48

y=6

y=6

x=8

burrito price=$8

Taco Price=$6

Consider the line y=9x-8
jasenka [17]

Answer:

y=9x+75

Step-by-step explanation:

since we know that the slope must be the same for two lines to be proportional, we are gonna start there.

so our equation is: y= 9x + b

we need to find b to complete our equation, so substitute in the points we were given.

3 = 9(-8) + b

so now,

3 = -72 + b

now we have to isolate b to find out what it is,

3  =  -72 + b

+72   +72

so now: 75= b

Put that back into the starting equation: y = 9x + 75
