Answer:

ΔCTA ≅ ΔDRA

Step-by-step explanation:

Triangles CTA and DRA are congruent by ASA postulate. This is because:

  • ∠1 ≅ ∠2 (given)
  • AC ≅ AR (given)
  • ∠A is the same for both triangles (they are opposite angles)

Then, correspondent angles and sides are congruent, for example, ∠3 ≅ ∠4

Solve each equation by taking square roots<br><br> 2n^2 -8=-33
densk [106]
2n^2 -8=-33 

&#10;2n^2=-33+8&#10; &#10;    Add \ 8 \ to \ both \ sides 

2n^2=-25 

n^2=- \dfrac{25}{2}   Divide \ both \ sides \ by \ 2 

n=+ \sqrt{ -\dfrac{25}{2} }  <span> Take \ the \ square \ root \ of \ both \ sides

n=+ \sqrt{ \dfrac{5i}{ \sqrt{2}}}

Creating and solving formulas for geometric series:mastery test
Levart [38]

Answer:

D. y = 5\cdot \Sigma_{i=0}^{4} \left(\frac{1}{3} \right)^{i}

Step-by-step explanation:

Let be y = \Sigma_{i = 0}^{4} \left[5\cdot \left(\frac{1}{3} \right)^{i}\right]. To find the equivalent expression we must use the following property:

y = c\cdot \Sigma_{i = 0}^{n} p(x) = \Sigma_{i=0}^{n} [c\cdot p(x)] (1)

Based on this fact, we find the following equivalence:

y = 5\cdot \Sigma_{i=0}^{4} \left(\frac{1}{3} \right)^{i}

Hence, the correct answer is D.
