Find the measure of c. A. 40 B. 70 C. 90 D. 50

Mathematics
1 answer:
Juliette [100K]4 years ago
4 0

Answer:

D. 50

Step-by-step explanation:

a = 90° (angle subtended in semicircle)

a + c + 40° = 180° (by angle sum postulate of a triangle)

90° + c + 40° = 180°

c + 130° = 180°

c = 180° - 130°

c = 50°

Which expression has a value of -2? *<br> O 1-4+121<br> O 121 +1-41<br> O 141-121<br> O 1-21-1-41
irga5000 [103]

Answer:

None.

Step-by-step explanation:

1 - 4 + 121

= -3 + 121

= 118

121 + 1 - 41

= 122 - 41

= 81

141 - 121

= 20

1 - 21 - 1 - 41

= -20 - 1 - 41

= -21 - 41

= -62

None of the expressions have a value of -2.

Which is the equation of the parabola?
mestny [16]

Answer:

  • y = -1/20(x + 3)²

Step-by-step explanation:

<u>Consider the parent function:</u>

  • y = x²

The graph of the function open up and the vertex is at the origin, the point (0, 0)

Now, if it opens down, it means it is a reflection of the parent function over x axis, hence it has a negative coefficient, the function becomes:

  • y = -x²

The vertex is shifted to the point (-3, 0). It means the function also translated left by 3 units, the function becomes:

  • y = -(x + 3)²

<u>Since all the options have 1/20 as a coefficient, our function is:</u>

  • y = -1/20(x + 3)²

This is option B
