Answer:

The answer is perfect square.

Step-by-step explanation:

A number whose square roots are integers or quotients of integers - perfect square.

The square of a number is a number multiplied by itself. Like 2 x 2 , 5 x 5 etc.

The perfect squares are the squares of the whole numbers like : 1, 4, 9, 16, 25, 36, and so on.

The scale on a map is 1 :50000.

mestny [16]

Answer:

The actual area of the field in square kilometers is $30000000 km^2$

Step-by-step explanation:

Scale : 1 cm = 50000 km

Area of field on map = $1.2 cm^2$

Now , 1 cm = 5000 km

$1 cm^2 = (5000 km)^2$

We are supposed to find the actual area of the field in square kilometers.

So, the actual area of the field in sq. km = $1.2 \times (5000)^2$

Actual area of the field in sq. km $=30000000 km^2$

Hence the actual area of the field in square kilometers is $30000000 km^2$

A park is showing a movie on the lawn. The base of the screen is 6 feet off the ground and the screen is 22 feet high (see figur

inessss [21]

Answer:

A. 61.82°;

15.64°

B. 33.37°

Step-by-step explanation:

✍️Angle of elevation from 15 ft:

A right triangle is formed. Apply trigonometric ratios formula to find the angle of elevation from 15 ft.

Thus,

Length of the side Opposite to reference angle = 22 + 6 = 28 ft

Adjacent length = 15 ft

Thus, we would have:

$tan(\theta) = \frac{opp}{adjacent} = \frac{28}{15}$

$tan(\theta) = 1.8667$

$\theta = tan^{-1}(1.8667)$

$\theta = 61.82$ (2 d.p)

✍️Angle of elevation from 100 ft:

Thus,

Length of the side Opposite to reference angle = 22 + 6 = 28 ft

Adjacent length = 100 ft

Thus, we would have:

$tan(\theta) = \frac{opp}{adjacent} = \frac{28}{100}$

$tan(\theta) = 0.28$

$\theta = tan^{-1}(0.28)$

$\theta = 15.64$ (2 d.p)

✍️Distance you'd be from the screen if you lie on the ground and make an angle of elevation of 40° to the top of the screen:

Adjacent length = your distance from the screen = x

Opposite length = 22 + 6 = 28 ft

Angle of elevation = 40°

Tge trigonometric ratios formula to use would be:

$tan(\theta) = \frac{opp}{adjacent}$

Plug in the values

$tan(40) = \frac{28}{x}$

Multiply both sides by x

$x*tan(40) = 28$

Divide both sides by tan(40)

$x = \frac{28}{tan(40)}$

$x = 33.37$ (2 d.p)

Write the polynomial in factored form.

Furkat [3]

Answer:

4x(x -4)(x +6)

Step-by-step explanation:

The factoring of 4x³ +8x² -96x will be such that the leading coefficient is 4 and the product of all constants is -96. Only one answer choice matches:

4x(x -4)(x +6)
