What is an equation that goes through the point (-7, 10) and is perpendicular to the line -2x-4y=9
algol13

Step-by-step explanation:

m1.m2= -1

(4y = -2x -9)= (y = -1x/2 -9/4)

-1/2.m2= -1

m2 = 2

formula = y - y1 = m2 ( x - x1)

y - 10 = 2 ( x - (-7))

y - 10 = 2x + 14

y = 2x + 24

An airplane flies at a rate of 356 km/h. the plane travels a total distance of 1424 km. (use distance = rate * time for your equ
frozen [14]

Your distance is 1424 and your rate is 356. As you said, d = r*t. Since you don't have the time you would do 1424 divided by 356. This leaves you with a time of 4 hours. (Don't forget units!)

SOMEONE HELP ME ASAP PLZZ!!!
Black_prince [1.1K]

Answer:

The distance of the plane from the base of the tower is 25.5 foot.

Step-by-step explanation:

As given

Max is in a control tower at a small airport.

He is located 50 feet above the ground when he spots a small plane on the runway at an angle of depression of 27°.

Now by using the trigonometric identity.

tan\theta = \frac{Perpendicular}{Base}

As shown in the figure given below

Perpendicular = CB

Base = AC = 50 feet

\theta = 27^{\circ}

Put in the identity.

tan\ 27^{\circ} = \frac{CB}{AC}

tan\ 27^{\circ} = \frac{CB}{50}

tan\ 27^{\circ} = 0.51\ (Approx)

Put in the above

0.51 = \frac{CB}{50}

CB = 0.51 × 50

CB = 25.5 foot

Therefore the distance of the plane from the base of the tower is 25.5 foot.
