Answer:

5. the given ordered pair is not a solution 6. the given ordered pair is a solution 7. the given ordered pair is a solution

Step-by-step explanation:

5. 8 = -4(-2) => 8 = 8 (true)

8 = 1/2(-2) + 7 => 8 ≠ 6 (false)

the given ordered pair is not a solution

6. 3 + 5(1) = 8 => 8 = 8 (true)

4(3) - 5(1) = 7 => 7 = 7 (true)

the given ordered pair is a solution

7. -5 = 4 - 9 => -5 = -5 (true)

4 + (-5) = -1 => -1 = -1 (true)

the given ordered pair is a solution

Answer:

Explanation:

according to the coordinates the triangles is right at the pair (2, -3)

the area of the triangle = height × base × 1/2

the height is the line passing through the pairs (-1, 6) and (2, -3)

h² = (2-(-1))²+(-3-6)²

h² = 3² + (-9)²

h² = 9 + 81

h² = 90

h = √90

the base is the line passing through the pairs (5, -2) and (2, -3)

b² = (2-5)²+(-3-(-2))²

b² = 3² + (-3+2)²

b² = 9 + 1

b² = 10

b = √10

A = h×b×1/2

A = √90×√10×1/2

A = √900×1/2

A = 30×1/2

A = 15 u²

Work out the area of this semicircle.Take pie to be 3.142 and give your answer to 2 decimal places 10cm

rosijanka [135]

Answer:

The area of the semi circle $A = 157.1 cm^2$

Step-by-step explanation:

Explanation:-

Given radius of circle 'r' = 10 cm

The area of the circle formula

$A = \pi (r)^{2}$

The area of the semi circle formula

$A = \frac{\pi (r)^{2} }{2}$

taking π =3.142

$A = 3.142 X \frac{(10)^2}{2}$

On calculation , we get

$A = 157.1 cm^2$

Final answer:-

The area of the semi circle $A = 157.1 cm^2$
