  • Left to Right

<u>Geometry</u>

  • Radius: r = d/2
  • Surface Area of a Sphere: SA = 4πr²

Step-by-step explanation:

<u>Step 1: Define</u>

d = 19 cm

<u>Step 2: Find </u><em><u>SA</u></em>

  1. Substitute [R]:                    r = 19 cm/2
  2. Divide:                                r = 9.5 cm
  3. Substitute [SAS]:               SA = 4π(9.5 cm)²
  4. Exponents:                        SA = 4π(90.25 cm²)
  5. Multiply:                             SA = 361π cm²
  6. Multiply:                             SA = 1134.11 cm²
  7. Round:                               SA ≈ 1134 cm²

Given g(x)=-x-2g(x)=−x−2, find g(0)g(0).
MaRussiya [10]

Answer:

g(0) = -2

Step-by-step explanation:

Given - g(x) = -x - 2

To find - g(0)

Proof -

We have given the function ,

g(x) = -x - 2

For finding the value of g(0), we just have to put x = 0 in g(x),

We get

g(0) = -0 - 2 = -2

⇒g(0) = -2

Please put the explanation!
BaLLatris [955]

Answer:

60

Step-by-step explanation:

In order to get this answer, we must know that a triangle's angles add up to exactly 180. Also, Angles that intersect will have congruent, opposite sides. The last thing is that a line is = 180 degrees. So, the triangle with the 94 and the 142, you can use that. the angle next to the 142 is going to be 180-142 which is 38 and since the other angle is opposite 94, as well. when you add those up u get 132 and 180-132= 48 which is the missing angle for the far right triangle. then, you get the opposite of that angle, put that in the other triangle, do the same with the 72, and add those up to get 120 and since a triagle adds up to 180, 180-120 = 60. So, 60 is your missing angle. Cheers
