Answer:

The powers of 10 they are multiplied by.

Step-by-step explanation:

Since there base number is 42, and zeros are determined by the multiplication of 10, they are different based on the power of 10 they are multiplied by. If you've heard of scientific notation, the equations for both numbers are different based on the power of 10 they are multiplied by. In this one, the base is 42, and the powers of 10 are different.

What is the value of i^20+1?<br> A. 1<br> B. –1<br> C. –i<br> D. i

lisov135 [29]

ANSWER

${i}^{20} + 1 =2$

EXPLANATION

The given expression is;

${i}^{20} + 1$

Recall that, in complex numbers

${i}^{2} = - 1$

We use this identity to simplify the given expression:

${i}^{20} + 1 =( {i}^{2})^{10} + 1$

This implies that:

${i}^{20} + 1 =( - 1)^{10} + 1$

${i}^{20} + 1 =1+ 1$

${i}^{20} + 1 =2$

If AJKL = ARST, which congruences are true by CPCTC? Check all that apply.

evablogger [386]

Based on the CPCTC theorem, the congruences that are true about the given triangles are:

B. ∠K ≅ ∠S

C. KL ≅ ST

D. JK ≅ RS

<h3>What is the CPCTC Theorem?</h3>

According to the CPCTC theorem states that if two triangles are congruent to each other, then, all their corresponding parts will be congruent to each other.

Given that triangles JKL and RST are congruent to each other, therefore:

∠J ≅ ∠R

∠K ≅ ∠S

∠L ≅ ∠T

JK ≅ RS

KL ≅ ST

JL ≅ RT

Therefore, the congruences that would be true by CPCTC are:

B. ∠K ≅ ∠S

C. KL ≅ ST

D. JK ≅ RS
