Answer:

-84 + 10i

Step-by-step explanation:

Standard Complex Form: a + bi

Step 1: Evaluate

√-100 = √-1 x √100 = i x 10 = 10i

-84 = -84

Step 2: Combine

10i - 84

Step 3: Rearrange

-84 + 10i

Answer:

Last Option

Step-by-step explanation:

√-100 - 84

(√(100×-1)) - 84

(√100)(√-1)-84

√-1 = i

10i - 84 or -84 + 10i

The owner of a new restaurant wants to have seating for more than 75 people. There is currently a
Fudgin [204]

Answer:

4m+3>75

Step-by-step explanation:

Given:

Number of people to be seated should be greater than 75.

Let n be the number of people. So,

n > 75

Now, there is a single private chef's table that can seat 3 people.

Tables bought by the owner = m

Number of people seated in 1 table = 4

So, number of persons that can be seated in m tables = 4\times m=4m

Now, total number of persons that can be seated in these two types of tables is the sum of 3 and 4m

Therefore, n = 4m+3

But, n>75

Hence, the inequality to show the situation is:

4m+3>75

Which piece of additional information can be used to prove △CEA ~ △CDB?
Slav-nsk [51]

<u>Answer-</u>

<em>The correct answer is</em>

<em>∠BDC and ∠AED are right angles</em>

<u>Solution-</u>

In the ΔCEA and ΔCDB,

m\angle BCD=m\angle ACE

As this common to both of the triangle.

If ∠BDC and ∠AED are right angles, then m\angle E=90=m\angle D

Now as

∠BCD = ∠ACE and ∠BDC = ∠AED,

∠DBC and ∠EAC will be same. (as sum of 3 angles in a triangle is 180°)

Then, ΔCEA ≈ ΔCDB

Therefore, additional information can be used to prove ΔCEA ≈ ΔCDB is ∠BDC and ∠AED are right angles.
