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.

(x+2)·2x + (x-1)^2= 2 ?
lisov135 [29]

Answer:

x = 1/3, x = -1.

Step-by-step explanation:

2x(x + 2) + (x - 1)² = 2

Distribute the 2x into x + 2.

2x² + 4x + (x - 1)² = 2

Square (x - 1).

2x² + 4x + x² - x - x + 1 = 2

Combine terms.

2x² + x² + 4x - 2x + 1 = 2

Combine terms again.

3x² + 2x + 1 = 2

Subtract 2 from both sides.

3x² + 2x - 1 = 0

Factor.

(3x - 1)(x + 1) = 0.

Finding the x-values here is the same thing as finding the 0s, so set both of the expressions to 0.

3x - 1 = 0

Add 1 to both sides.

3x = 1

Divide by 3.

x = 1/3.

x + 1 = 0

Subtract 1 from both sides.

x = -1.

future value = P × (1+ i)t `"present value" = "P" / (1 + i)^"t"` What would be the value of $100 after 10 years if you earn 11 p
vesna_86 [32]

Answer:

B) \simeq 283.94  (in $)

Step-by-step explanation:

Value of $100 after 10 years  if I earn 11 %  interest per year is given by,

$ (100 \times (1 + \frac{11}{100})^{10})

\simeq 283.94  (in $)

We know that if,

Principal= P

Rate of annual compound interest = r %

Time = n year

then amount, A  = P \times (1 + \frac{r}{100})^{n}
