Answer:

aₙ = 2250n - 750

Step-by-step explanation:

<u>This is an arithmetic progression with:</u>

The first term a₁ = 1500
Common difference d = 2250

<u>Required expression is:</u>

aₙ = a₁ + (n - 1)d
aₙ = 1500 + (n - 1)2250 =
1500 + 2250n - 2250 =
2250n - 750

it rained 2.79 inches in july. What was the average daily rainfall in July? (Hint: July has 31 days.)

natali 33 [55]

Rainfall in July = 2.79 inches.

July has 31 days.

2.79 : 31 = x : 1 Set up the proportion

2.79 / 31 = x/1 Cross multiply and switch.

2.79*1 / 31 = x Do the division

SOMEONE HELP ME ASAP PLZZ!!!

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.
