I WILL MARK BRAINLIEST

Step-by-step explanation:

it does not matter, if you understand the equation itself. look at the graph ! what is the curve doing ?

I don't know the options of the pull-down menus, so I will give you my best guesses based on the facts :

the domain of a function is the set or interval of all valid x (or input) values.

the range of a function is the set of interval of all valid y (or functional result) values.

so, clearly, x is in the interval (-infinity, +infinity). which is therefore the domain.

please conduct the round brackets. they indicate that the specified interval limits are not included (as infinity is not a value, only a concept, and can never be reached).

and y is in the interval of (0, +infinity). which is therefore the range.

we have to use the round brackets also for 0, as the function will never deliver the value 0, but its tendency or limit goes there (but again, only in infinity, which will never be reached).

the function continuously decreases when x increases.

again, I am not sure what the options are here, and what your teacher wants to "hear".

Answer:

174 Sq feet

Step-by-step explanation:

30+90+54 just add.

Answer:

174 sq ft

Step-by-step explanation:

Formula:

A = Lw

Note:

A rectangle has 3 set of different side.

Solve:

A = Lw

A = 5 × 9

A = 45 ×  2

A = 90

A = Lw

A = 5 × 3

A = 15× 2

A = 30

A = Lw

A = 3 × 9

A = 27× 2

A = 54

90 + 30 + 54 = 174 sq ft

The substitution that should be used to rewrite 6(x+5)^2 + 5(x+5) - 4 = 0 is u = x + 5

These are equations that has a leading degree of 2. Given the expression

6(x+5)^2 + 5(x+5) - 4 = 0

In order to simplify this equation, we will replace the reoccuring term by a variable.

From the equation we can see that (x+5) is occuring the most. Let u = x + 5 so that:

6u^2 - 5u - 4 = 0

Hence the substitution that should be used to rewrite 6(x+5)^2 + 5(x+5) - 4 = 0 is u = x + 5

Please mark brainliest

Answer:

So we are given the length, width, and height and we are also told that we need to find the surface area.  The formula to finding the surface area of a rectangular prism is [tex]S=2(w*h+l*w+l*h)[/tex]

We just plug in the values and solve

[tex]S = 2(9\ in * 3.5\ in+6\ in * 9\ in + 6\ in * 3.5\ in)[/tex]

[tex]S = 2(31.5\ in^2 + 54\ in^2+21\ in^2)[/tex]

[tex]S = 2(106.5\ in^2)[/tex]

Answer:

44 minutes

Step-by-step explanation:

Given:

Michelle started doing a puzzle at 7:50 p.m. She finished the puzzle at 8:34 p.m.

To Find:

How long did Michelle work on the puzzle?

Solve:

Began Time ⇒ 7:50 p.m

End Time     ⇒ 8: 34 p.m

Since they are both p.m we could just subtract 8:34 by 7:50.

But first we know that:

8: 34 the 34 can't be subtracted by 7:50 the 50.

Thus we know that:

1 Hour = 60 minutes

Hence,

changing 8:34 p.m from 1 hour to 60 minutes. Which given us 7:94.

Then,

7:94 - 7:50

= 44

Hence, Michelle work on the puzzle for 44 minutes.

Depreciation is the reduction in the value of an asset over time, due in particular to wear and tear.

Your information is incomplete. Therefore, an overview will be given.  depreciation refers to an accounting method used to allocate the cost of a tangible or physical asset over its useful life.

To calculate depreciation, subtract the asset's salvage value from its cost. The result is the depreciable basis or the amount that can be depreciated. Divide this amount by the number of years in the asset's useful lifespan.

Answer:

x = 20

Step-by-step explanation:

Angle x and the 90 degree  angle and 70 form a straight line so they add to 180

x+90+70 = 180

Combine like terms

x + 160 = 180

x = 180-160

x = 20

=============================================================

Explanation:

There are 7 professors and 9 instructors (first and last items mentioned).

So there are 7+9 = 16 people who are either a professor or an instructor, but not both. I'm assuming the job titles do not overlap, ie no one person has more than one title. The events "professor" and "instructor" are mutually exclusive. I'm leaving out the associate professors and assisant professors.

In total, there are 7+9+9+9 = 34 faculty members.

--------------

We found there are 16 faculty members who are either a professor or an instructor, out of 34 total members.

This must mean the probability we want is 16/34 = 8/17

Side note: 8/17 = 0.4706 = 47.06% approximately

Answer:

18 degrees heres youre answer!

Step-by-step explanation:

If Angle 1 is x, and Angle 2 is 9x (because one angle is 9 times as large as the other), then x + 9x = 180. Add like terms: 10x = 180. solve for x by dividing both sides by 10. Therefore, x = 18 degrees = smaller angle.

Angles in a triangle add to 180 degrees, so angle A is 180-108-31=41 degrees.

The inverse demand function views price as a function of quantity. The inverse demand function of the firm will be:

[tex]\rm P=9-0.25Q[/tex]

The inverse demand function is the function that represents price as the function of quantity demanded. The graph of inverse demand puts a price on the y axis and the quantity demanded on the x-axis.

a. The inverse demand function of the firm will be calculated as follows:

The demand function is:

[tex]\rm Q=36-4P[/tex]

The inverse demand function is the demand function in terms of price. Therefore inverse demand function will be:

[tex]\rm Q=36-4P\\\\4P=36+Q\\\\P=\dfrac{36}{4}+\dfrac{Q}{4}\\\\P=9+\dfrac{Q}{4}\\[/tex]

Step-by-step Non-explanation:

The first term ( -4.9(t-4)^2 ) can never be positive, so the maximum height of 80 meters is achieved when t = 4. So the rocket will reach its maximum height after 4 seconds.

The approximate maximum height of the rocket's path is 597.13 meters.

Observer sees the rocket 160 meter away from the place where rocket launched.

75° is the angle between observer and rocket, when the rocket reaches its maximum height.

Here, if we assume a triangle whose base = distance between rocket launch point and the observer.

Height = Maximum height of the rocket

Here, Base = 160 meter & let, maximum height = h

tan 75° = [tex]\frac{height}{base}[/tex]

⇒ tan 75° = [tex]\frac{h}{160}[/tex]

⇒ h = 160 tan 75°

⇒ h = 597.13 (approx)
