Given that x - y = 5 and xy = -6/1/2,
find the value of x² + y².​

Answers

Answer 1

Answer:

24

Step-by-step explanation:

(x - y)² = x² + y² - 2xyx² + y² = (x - y)² + 2xy

Substitute given values

x² + y²  = 5² + 2(-6/12) = 25 - 1 = 24
Answer 2

Answer:

Given that x - y = 5 and xy = -6/1/2,

Step-by-step explanation:

the value of x² + y².

=(x-y)²+2xy=5²+2×[-6 1/2]=25-13=12 is your answer

The probability of rolling a number cube and getting a 6 and 3.

Answers

We have to find out the probability of getting 6 and 3,

Since this only one roll it is not possible to get 2 numbers in one roll

So, I will presume you want the probability of getting 6 or 3,

Total number of outcomes= {1,2,3,4,5,6} = 6 outcomes

Number of favorable outcomes = {3,6} = 2 outcomes

Probability of rolling 6 or 3 = [tex]\frac{Number'of 'favorable' outcomes}{Total' number 'of' outcomes}[/tex]

= 2/6

= 1/3 or 0.33333%

Therefore the probability of rolling 6 or 3 is one in three chances

Arc AD=98 and I need help with both problems below

Answers

Answer:

arc DC = 64

angle DCQ = 32

Step-by-step explanation:

Hello There!

The circumference of a normal circle is 360

Given that arc AD = 98 and having found arc ABC we can find arc DC by subtract the known arcs from 360

360 - 98 - 198 = 64

Hence arc DC = 64

The problem wants us to find angle DCQ having found arc DC

Remember like stated before an included angle is equal to 1/2 its opposite arc

64/2=32

so angle DCQ = 32

Answers

Answer:

9 by (3x + 2) units

Step-by-step explanation:

Note that 9 is a factor of both 27x and 18.  Therefore,

27x + 18 factors into 9(3x + 2).

Answers

Answer:

In my opinion i would think A but it might be P also, sorry im not sure but thats my best guess.

Step-by-step explanation:

Figure 4 has rotational symmetry but no line symmetry.

Option D is correct.

Symmetry :

The rotational symmetry of a shape explains that when an object is rotated on its own axis, the shape of the object looks the same.

Some of the examples are square, circle, hexagon.A line of symmetry is a line that cuts a shape exactly in half. It means that if we fold the shape along the line, both halves would match exactly.

From given figure, It is observed that figure 4 has rotational symmetry but no line symmetry.

So first the formula of finding the area of a triangle is

A= 1/2 (b) (h)

If we turn the triangle we can do that.

so,

A=1/2 (6)(6)

A=1/2(36)

1/2 of 36 is 18

So, the answer is 18 cm
