Answer:

10.) 12 + 3i

11.) 3 - i

A math conjugate is formed by changing the sign between two terms in a binomial. For instance, the conjugate of x + y is x - y. We can also say that x + y is a conjugate of x - y.

12.) x² - 8x + 17 = 0

Let's solve your equation step-by-step.

x² − 8x + 17 = 0

Step 1: Use quadratic formula with a=1, b=-8, c=17.

x=  −b±√b2−4ac  / 2a

x=  −(−8) ± √(−8)2−4(1)(17)  / 2(1)

x=  8 ± √−4  / 2

There are no real solutions.

13.) x²- 8x + 17 = 0

Let's solve your equation step-by-step.

x² − 8x + 17 = 0

Step 1: Use quadratic formula with a=1, b=-8, c=17.

x=  −b ± √b2−4ac  / 2a

x=  −(−8) ± √(−8)2−4(1)(17)  / 2(1)

x=  8 ± √−4  / 2

There are no real solutions.

Step-by-step explanation:

To solve a quadratic equation by factoring,

Put all terms on one side of the equal sign, leaving zero on the other side.

Factor.

Set each factor equal to zero.

Solve each of these equations.

Check by inserting your answer in the original equation

I hope this helps!

Dilating a triangle changes the angles and side length of the triangle. A. True B. False
Bogdan [553]
False, it may change the side length (not 100% sure) but I know for sure dilating doesn't change the angle

Linda calculated that the saucer for her teacup has an area of 50.24 square centimeters. What is the saucer's circumference?
Brilliant_brown [7]

Answer:

The saucer's circumference is <u>25.12 centimeter</u>.

Step-by-step explanation:

Given:

Linda calculated that the saucer for her tea cup has an area of 50.24 square centimeters.

Use 3.14 for π.

Now, to find the saucer's circumference.

So, we get the radius first by putting the formula of area:

Area = 50.24 square centimeters.

Let radius be r.

Area = \pi r^2.

Area = \pi\times r^2.

As given we use 3.14 for π.

50.24 = 3.14\times r^2.

<em>Dividing both sides by 3.14 we get:</em>

16=r^2.

<em>Using square root on both sides we get:</em>

4=r

r=4

Thus, the radius = 4 centimeters.

Now, to get the circumference we put formula:

Circumference=2\pi r

Circumference=2\times \pi \times r

Circumference=2\times 3.14\times 4

Circumference=25.12

Circumference = 25.12 centimeter.

Therefore, the saucer's circumference is 25.12 centimeter.
