Answer:

The altitude is changing at a speed of 200 √3 km/hr

Step-by-step explanation:

Here, we want to know how far the altitude of the plane is changing

we are told that the airplane makes an angle of 60 degrees with the ground

So therefore , the rate of change of its altitude will be ;

sin 60 = x/ 400

x = 400 sin 60

x = 400 * √3/2

x = 200 √3 km/hr

Determine 4th term in the geometric sequence whose first term is -2 and whose common ration is -5.
anygoal [31]

Answer:

a_{4} = 250

Step-by-step explanation:

To obtain any term in the geometric sequence multiply the previous term by the common ratio r

here r = - 5 and a_{1} = - 2, hence

a_{2} = - 2 × - 5 = 10

a_{3} = 10 × - 5 = - 50

a_{4} = - 50 × - 5 = 250

Make x the subject of the formula y=(5t+5x)
Elan Coil [88]

Answer:

(y-5t)/5=x

Step-by-step explanation:

y=5t+5x

factorize

y=5(t+x)

divide both sides by 5

y/5=5(t+x)/5

y/5=t+x

make x to stand alone

y/5-t=x

take lcm of 5 and 1

y/5-5t/5

y-5t/5=x

Anyone mind taking the time to help me? Ty?
alekssr [168]

Answer:

Both Lindsay and Sharon are wrong.

Step-by-step explanation:

When Lindsay was doing her problem, she put 100 on the bottom and 45 on the top, when it should have been the other way around.

Sharon would have been correct if she had used the right measuring unit. 2/5 of a milliliter should have been 2/5 of a liter.
