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.

Step-by-step explanation:

plug in each given number for x in the function:

- (-4) - 5

a negative negative is also a positive

4 - 5 = -1

- (-3) - 5

3 - 5 = -2

0 - 5 = -5

1 - 5 = -4

4 - 5 = -1

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)

The maximum height of the rocket is 597.13 meters (approx).

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]

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

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:

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.

The number of students that are expected to carry a backpack is = 378

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.

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

The bird (B) from its nest (N) is 17202 ft.

Trigonometric functions defined as the functions which show the relationship between angle and sides of a right-angled triangle.

This is very obviously a right triangle problem.

Side BO is the hypotenuse of the triangle, measuring 21000.

Side BN is the side adjacent to the given angle B, 35 degrees.

This is the cosine ratio:

cos∅ = adj/hyp

substitute the values

cos35° = x/21000 and solving for x:

21000.cos(35°) = x

x = 17202.19 or, rounded as we need:

x = 17202

Hence, the bird (B) from its nest (N) is 17202 ft

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

The future value after 4 years will be $8156.49 if the value of the car today is $13,000 but will lose 11% of its value each year for the next several years.

Based on an estimated growth rate, the future value is the amount that an asset will be valued at a future date. The computation assumes that at the start date, a fixed amount of cash is made available for investment and that it increases at a constant rate until the selected future date.

We have:

Current value of the car = $13,000

Depreciation rate = 11%

Time n = 4 years

[tex]\rm Future \ value = (value \ at \ present) ( 1- \dfrac{depreciation \ rate}{100})^n[/tex]

[tex]\rm Future \ value = (13000)(1-\frac{11}{100} )^4[/tex]

Future value = $8156.49

Thus, the future value after 4 years will be $8156.49 if the value of the car today is $13,000 but will lose 11% of its value each year for the next several years.
