What is 11 minus a number to equal -3

NNADVOKAT [17]

Answer:

Step-by-step explanation:

11 - n = -3

-n = -3 - 11 = -14

n = 14

add n to both sides of equation and add 3 to both sides of equation:

11 - n + n + 3 = -3 + n + 3 ----> n = 14

An airplane, flying at a constant speed of 360 mi/hr and climbing at a 30 degree angle, passes over a point P on the ground at a

Klio2033 [76]

Answer:

Step-by-step explanation:

Given

velocity of airplane is 360 mi/hr

inclination of climbing $30^{\circ}$

Plane velocity can be divided in to x & y component

Velocity in x component is $360\cos30$

Velocity in y component is $360\sin30$

Thus distance traveled in x axis is $=360\cos30\times \frac{1}{60}$

=60cos30=51.96 miles

Distance travel in upward direction i.e. in Y axis

$=360\sin30\times \frac{1}{60}=30 miles$

so total altitude gain by plane is 30+4=34 miles

Horizontal distance traveled is 51.96

inclination w.r.t to point p

$tan\theta =\frac{34}{51.96}=0.654$

$\theta =33.18^{\circ}$

Initial inclination is $90^{\circ}$

therefore rate at which its distance is changing is $360\cos30=311.76 miles /hour$

Across a horizontal distance of 25 feet, a roller coaster has a steep drop. The height of the roller coaster at the bottom of th

I am Lyosha [343]

Answer:

For each horizontal foot, the roller coaster changes 6 feet of height.

Step-by-step explanation:

Across a horizontal distance of 25 feet, a roller coaster has a steep drop.

So the run is 25 feet.

The height of the roller coaster at the bottom of the drop is -150 feet. (Negative sign is given because it is measured from the top to bottom)

So the rise is 150 feet.

The slope of the roller coaster is,

$m=\dfrac{\text{Rise}}{\text{Run}}=\dfrac{150}{25}=6$

Slope of 6 means, for 1 unit of run, the object has a rise of 6 units.

Therefore, for each horizontal foot, the roller coaster changes 6 feet of height.
