what is 9+2 I WILL MARK BRAINIEST

Step-by-step explanations:

Since the domain is a set of all real numbers, all the expression are with respect to real numbers.

a. 3 x,y : x/y < 1 ∧ y/x < 1

b. ∀x > 0, 1/x > 0

c. 3 x,y : x + y = xy

d. ∀x > 0 ∧ y > 0, x/y > 0 ∧ y/x > 0.

3 means "there exists"

∀ means "for every value of"

∧ means "and"

Answer:

x = 4

Step-by-step explanation:

Given:

(√x + 2)(√x - 2) = 0

Required:

Find x

SOLUTION:

√x(√x - 2) + 2(√x - 2) = 0 (distributive property)

x - 2√x + 2√x - 4 = 0

x - 4 = 0

x - 4 + 4 = 0 + 4

x = 4

Answer:

1 : 4

Step-by-step explanation:

Answer:

10.44 feet

Step-by-step explanation:

You need to use the Pythagorean Theorem twice.  

First we have to find the diagonal for the base.

6²+8²=x²

36+64=x²

100=x²

√100=x

x=10

Now we can find d.

10²+3²=x²

100+9=x²

109=x²

√109=x

x=10.44 feet

Answer:

explanation:

Step-by-step explanation:

1: Well, of course since you’re going below sea level, the number is gonna be negative. so you’re gonna take -240 + -12. which is -252. but then you’re gonna take the -252 and add POSITIVE 80. so now if you take -252 + 80 you get -172. so the diver is 172 meters below the surface

2: -127.1

3: The highest temperature is POSITIVE 110°F. But since the lowest one is NEGATIVE 34°F, you’re gonna want to take 110 - 110 to get 0, then go 34 less than 0. so 110 + 34 is 144. so the difference is 144°

Answer:

[tex]8.3125[/tex]pounds

Step-by-step explanation:

We are given that

Density of ethyl acetate at 25 degrees =[tex]0.902g/ml[/tex]

We have to find the number of pounds in 133 ounces weigh.

To find the number of pounds in 133 ounces we will use unitary method

By using unitary method

We know that

1 ounce=0.0625 pounds

133 ounce=[tex]133\times 0.0625[/tex]pounds

133 ounce=[tex]8.3125[/tex]pounds

Hence,8.3125 pounds would 133 ounces weigh.

A composite number is a positive integer that can be formed by multiplying two smaller positive integers.

Answer:

36 cm

Step-by-step explanation:

Answer:

Step-by-step explanation:

y + 2= -1/2(x - 0)

y + 2 = -1/2x + 0

y = -1/2x - 2

-1/2x = -2

x = 4

Answer:

  3

Step-by-step explanation:

The angle bisector BD makes left-side segments proportional to right-side segments. We see that CD is half of CB, so we expect the same proportion between AD and AB.

  AD/AB = CD/CB

  x/6 = 4/8 = 1/2 . . . . fill in the values, simplify the fraction

  x = 6(1/2) . . . . . . . . multiply by 6

  x = 3

Answer:

-5/7

Step-by-step explanation:

With the equation y = mx + b, m is the slope of the line.

Since the equation is y = -5/7x - 1, m is -5/7

So, the slope of the line is -5/7

Answer:

m = -5/7

slope = -5/7

Step-by-step explanation:

Use y = mx + b to find the slope m.

Answer:

b = [tex]\frac{3ab - a - 2}{2}[/tex]

Step-by-step explanation:

We have an algebraic expression and are asked to solve for b.

a(3b - 1) = 2b + 2

To solve we need to isolate b :

Distribute :

(a(3b) - a(1)) = 2b + 2

3ab - a = 2b + 2

2b + 2 = 3ab - a

Subtract 2 from both sides :

2b = 3ab - a - 2

Divide 2 from both sides :

b = [tex]\frac{3ab - a - 2}{2}[/tex]

Answer:

b = 2+a/ 3a-2

Explanation:

Obviously, the way you use trig ratios will depend on the problem. The problems you see in algebra and trig courses are a good sampling of the kinds of problems you run across in the real world. Some of them include ...

  finding height or widths based on a measure and an angle (SOH CAH TOA)

  finding areas based on side lengths and an angle (area formula)

  finding unknown sides or angles of a triangle (law of sines/cosines)

  finding bearing and/or distance (spherical trig relations, law of cosines)

As with solving problems of any kind, you choose the appropriate formula(s), fill in the known values, and solve for the unknown values. Sometimes a real-world problem will require solution of intermediate problems before the answer to the original question is found.

Answer:

290d + 245

Step-by-step explanation:

Hello! So what you do first is make two equations, then combine them.

For the food booths, the equation would be 15(4d) + 150

For the game booths, the equation would be 23(10d) + 95

Now simplify them.

Food booths: 60d + 150

Game booths: 230d + 95

Next, we combine the two equations to get one equation.

60d + 150 + 230d +95

Simplify even more...

290d + 245

This is going to be your equation. I don't know the number of days the fair went so I can't go any futher on this question. Hope this helps though!

Answer:

3562.6 m³

Step-by-step explanation:

In this question, we have to find the volume of a cylinder.

The formula to find the volume of a cylinder is V = πr²h

Plug in your values and solve.

Solve:

V = π(9)²(14)

V = π(81)(14)

V = π(1,134)

V = 3562.566069

Round to the nearest tenths place.

V = 3562.6

Don't forget that the units for volume is already cubed, or to the power of 3.

Your final answer would be 3562.6 m³

Answer:

142 is the correct answer (PEMDAS)
