djverab [1.8K]3 years ago
7 0

Answer:

The value of x fro the given equation is ( 4 + 2 i ) , ( 4 - 2 i )

I.e option D  

Step-by-step explanation:

Given equation as :

x² - 8 x + 41 = 0

For quadratic equation  ax² + b x + c = 0

The value of x = \frac{-b\pm \sqrt{b^{2}-4\times a\times c}}{2\times a}

∴ For equation x² - 8 x + 41 = 0

Or,                x = \frac{8\pm \sqrt{-8^{2}-4\times 1\times 41}}{2\times 1}

Or,                x = \frac{8\pm \sqrt{-100}}{2}

Or,                x = \frac{8\pm 10i}{2}

∴                  x = ( 4 + 2 i ) , ( 4 - 2 i )

Hence The value of x fro the given equation is ( 4 + 2 i ) , ( 4 - 2 i )

I.e option D     Answer

The statements that apply to the ratio of rice and water are:

  • The ratio of rice to water is 1 to 2.5
  • The ratio of water to rice is 2.5 to 1

<h3>Ratios</h3>

Ratios are used to compare quantities of different measurements

The entries on the table are given as:

<u>Rice          Water</u>

2                  5

3                  7.5

5                 12.5

8                 20

<h3>The ratios of both quantities</h3>

The ratio (r) of rice and water is then calculated as:

r = \frac{Water}{Rice}

Pick any corresponding table entry.

So, we have:

r = \frac{5}{2}

Divide

r = 2.5

This means that, the ratio of rice to water is 1 to 2.5, and the ratio of water to rice is 2.5 to 1

Vikas is the head of student council this year at his high school in London. He is responsible for planning the annual graduatio
Naily [24]

Answer:

C = 600 + 50s

Step-by-step explanation:

The students are planning to visits the Canada's wonderland. The students will spend a full day at the park.

The entry fee for each student is $50 and the bus cost is $600. Each student will pay $50 for entry into the park.

Let

the number of student  = s

cost of the trip = C

Relating the variable C and s

The total amount of money the student will pay for entry fee = 50 × s = 50s

Therefore, cost of the trip can be expressed as follows

C = 600 + 50s

The ratio of the number of Sam's CDs to the number of Alice's CD's is 7 to 8. Sam has 84 CDS.
Alex

Answer:

180 CDs

Step-by-step explanation:

So if Sam has 84 CDs, and the ratio from Sam to Alice is 7:8, we can do 84/7=12 so each number is equal to 12. Then we add up 7 and 8 and get 15, so we do 15*12 and we get 180.
