Interpreting the inequality, it is found that the correct option is given by F.

------------------

  • The first equation is of the line.
  • The equal sign is present in the inequality, which means that the line is not dashed, which removes option G.

In standard form, the equation of the line is:

x + 2y = 6

2y = 6 - x

y = -0.5x + 2

Thus it is a decreasing line, which removes options J.

  • We are interested in the region on the plane below the line, that is, less than the line, which removes option H.

------------------

  • As for the second equation, the normalized equation is:

3x^2 + 3y^2 = 12

3(x^2 + y^2) = 12

x^2 + y^2 = 4

  • Thus, a circle centered at the origin and with radius 2.
  • Now, we have to check if the line x + 2y - 6 = 0, with coefficients a = 1, b = 2, c = -6, intersects the circle, of centre x = 0, y = 0
  • First, we find the following distance:

d = \sqrt{\frac{|ax + by + c|}{a^2 + b^2}}

  • Considering the coefficients of the line and the center of the circle.

d = \sqrt{\frac{|1(0) + 2(0) - 6|}{1^2 + 2^2}} = \sqrt{\frac{6}{5}} = 1.1

  • This distance is less than the radius, thus, the line intersects the circle, which removes option K, and states that the correct option is given by F.

The two parallel sides of a trapezium are 19.8 and 7.2 and its area is 135 cm²..find its height
Virty [35]

Answer:

10cm

Step-by-step explanation:

the formula for an area of a trapezium:

\frac{(a + b) \times h}{2}  = area

where a and b are the parallel sides and h is the height. equating what we have:

\frac{(19.8 + 7.2) \times h}{2}  = 135

simplify the numerator by adding 19.8 and 7.2=27

\frac{27h}{2}  = 135

multiply both sides by 2

27h = 270

divide both sides by 27

h =  \frac{270}{27}  = 10

the height is 10cm
