4 0

Answer:

step 1. b = 102° (vertical angles)

step 2. one complete revolution equals 360°

step 3. a + b + c + 102 = 360

step 4. a + 102 + c + 102 = 360

step 5. a + c = 156°

step 6. 2a = 156 (vertical angles are equal)

step 7. a = 78°, c = 78°.

Find the sum of 3.0478 and 4.92 using the correct number of significant digits.
Nat2105 [25]

The sum of 3.0478 and 4.92 is 7.9678, which have 5 significant digits.

<u>Step-by-step explanation:</u>

We have , Number1 = 3.0478 and Number2  =4.92 . The significant digits of a number are digits that includes all digits except:

  • All leading zeros. For example, "013" has two significant figures: 1 and 3;
  • Trailing zeros when they are merely placeholders to indicate the scale of the number and  ,
  • Spurious digits introduced, for example, by calculations carried out to greater precision than that of the original data, or measurements reported to a greater precision than the equipment supports.

Here Number1 = 3.0478 and with significant digit rules Number2 = 4.9200 . Now, Sum of both numbers = Number1 + Number2

⇒Sum of both numbers = 3.0478 + 4.9200

⇒Sum of both numbers = 7.9678

∴ The sum of 3.0478 and 4.92 is 7.9678, which have 5 significant digits.

Identify the equation of the graph shown. A) y = 2x + 3 B) y = 2x - 3 C) y = -2x + 3 D) y = -2x - 3 4)
Anna35 [415]

Answer:

The answers provided aren't reasonable for this graph.

Step-by-step explanation:

The graph's y-intercept is -2, since that is the point where the line intersects the y-axis. The slope is 3x, because the distance from one point to the next is 3 up, 1 right. So the equation for the graph is y = 3x - 2.
