<u>Answer:</u>

$\sf 9x^2 - 12x^5 +6x$

<u>solving steps:</u>

$\hookrightarrow \sf (3x^2 + 6x^2 + 9x )- (4x^5 + 8x^5 + 3x)$

remove parenthesis

$\hookrightarrow \sf 3x^2 + 6x^2 + 9x - 4x^5 - 8x^5 - 3x$

group variables

$\hookrightarrow \sf 3x^2 + 6x^2 - 4x^5 - 8x^5 - 3x+ 9x$

simplify

$\hookrightarrow \sf 9x^2 - 12x^5 +6x$

Answer:

$12x^5-9x^2-6x$

Step-by-step explanation:

$\left(4x^5+8x^5+3x\right)-\left(3x^2+6x^2+9x\right)$

$4x^5+8x^5+3x-\left(3x^2+6x^2+9x\right)$

$(4x^5+8x^5):12x^5$ ( Combine like terms)

$12x^5+3x-\left(3x^2+6x^2+9x\right)$ (Apply the distributive law)

$12x^5+3x-9x^2-9x$

$(3x-9x):-6x$ ( Combine like terms)

$12x^5-9x^2-6x$

The only point outside of the line is (2, 0)

In order to find if a point is outside, inside or on the line, you simply have to put the number into the equation. If the result is both sides are equal, then it is on the line. If the left side is bigger than the right side, then it is outside of the line. If the right side is bigger than the left, then it is inside of the line. So lets plug in and see where (2, 0) falls.

(x - 2)^2 + (y + 3)^2 = 4

(2 - 2)^2 + (0 + 3)^2 = 4

0^2 + 3^2 = 4

0 + 9 = 4

9 = 4

Since the left side is bigger than the right, we know it is outside of the line.

An airplane climbs at an angle of 2.7" from an altitude of 4500 ft to an altitude of 5600 ft. How far does the airplane travel a

Dvinal [7]

Answer:

23,325 ft, about 4.42 miles

Step-by-step explanation:

The geometry of the situation can be modeled by a right triangle, where the side adjacent to the 2.7° angle of climb is the horizontal distance, and the side opposite is the vertical change in altitude. That change is ...

5600 ft -4500 ft = 1100 ft

and the angle relation is ...

tan(2.7°) = opposite/adjacent = (1100 ft)/(horizontal distance)

Multiplying this equation by (horizontal distance)/tan(2.7°) gives ...

horizontal distance = (1100 ft)/tan(2.7°) ≈ 23,325 ft

Dividing this by 5280 ft/mi gives ...

horizontal distance ≈ 4.42 mi

The airplane travels about 23,325 ft, or 4.42 miles, horizontally as it climbs.

Suppose an economy experiences an increase in unemployment across all industries. What is the result of this increase in unemplo

r-ruslan [8.4K]

The curve of production possibilities would shift inward because labor is considered a factor of production. By reducing productive resources, the maximum level of production will decrease and unemployment level increases.

In a Market Economy, Employment and Production Levels are set by balance between Supply and Demand. In this situation, a reduction on Demand means that Level of Production is higher than what Market can afford and there are two possibilities: (i) Lowering prices of goods and services, which may be perjudicial for businessmen and capitalists but may allow to sell this surplus, (ii) Firing some workforce to eliminate Supply surplus, since there is a relationship between Workforce and Production, which is tinged with other production factors as Technology and Skills.

Hence, the curve of production possibilities would shift inward because labor is considered a factor of production. By reducing productive resources, the maximum level of production will decrease and unemployment level increases.
