What is the volume of the sphere below?
Use the formula Var?
4 cm
A 16.75 cm
B 66.99 cm
C267.95 cm

Answer:

x^4 - 2.2x^2 - 4

Step-by-step explanation:

Given the following

R(x) = 2x4 – 3.2x^2 + 2x – 1 and C(x) = x4 – x2 + 2x + 3

Required

P(x)

Since P(x) = R(x) – C(x).

P(x) =   2x4 – 3.2x^2 + 2x – 1 – (x^4 – x^2 + 2x + 3).

Expand

P(x) = 2x4 – 3.2x^2 + 2x – 1 – x^4 + x^2 - 2x - 3

P(x) =   2x4 - x^4 - 3.2x^2 + x^2 + 2x - 2x -1 - 3

P(x) = x^4 - 2.2x^2 - 4

Hence the profit function is  x^4 - 2.2x^2 - 4

38+63+1=180

1=79

the answer is 79

Answer:

4 /15

Step-by-step explanation:

From the number cube :

Count of Numbers greater than 4 = 16

Sample space of number cube = 20

P(number greater than 4) = 16 / 20 = 4/5

Word : ATTENTION

Count of letters in attention = 9

Count of T's in attention = 3

P(choosing T) = 3 / 9 = 1/3

P(greater than 4, then T) = 4/5 * 1/3 = 4 /15

Answer:

-6x^2+24x

Step-by-step explanation:

3x(2-2x+6)

We have to distribute 3x to everything in the parenthesis.

3x(2)+3x(-2x)+3x(6)

6x-6x^2+18x

-6x^2+24x

3rd option

Step-by-step explanation:

The range are the values covered on the y- axis

The lowest value is - 2

The highest value is 6

Both points have a solid circle on them indicating y can equal those values

range { y : - 2 ≤ y ≤ 6 }

Answer:

Water flow becomes slower when it river bends

Step-by-step explanation:

Deposition occurs when a river loses energy.

Answer:

Once the river bends the flow of water reduces and sediment begins to build up. so I would say A

Answer: 1/45

Step-by-step explanation:

The probability that it will rain this week and then rain next week will be the multiplication of the both the probability that it'll rain this week and probability that it'll rain next week.

Therefore, the answer will be:

= P(rain this week) × P(rain next week)

= 1/9 × 1/5

= 1/45

Therefore, the answer is 1/45.

Answer:

2

Step-by-step explanation:

x + 1/x = 2

x + 1 = 2x

x = 1

x³ + 1/x³

1³ + 1/1³.

1 + 1/1 = 1 + 1 = 2

Answer:

C.5

Step-by-step explanation:

Fiona:

After t trials, she would have:

[tex]f(t) = 4.127(1.468)^t[/tex]

Karl:

After t trials, he would have:

[tex]k(t) = 0.897(1.992)^t[/tex]

At what number of trials would Fiona and Karl have the same number of beans?

This is t for which:

[tex]f(t) = k(t)[/tex]

So

[tex]4.127(1.468)^t = 0.897(1.992)^t[/tex]

[tex]0.897(1.992)^t = 4.127(1.468)^t[/tex]

[tex]\frac{(1.992)^t}{(1.468)^t} = \frac{4.127}{0.897}[/tex]

[tex](\frac{1.992}{1.468})^t = 4.6[/tex]

[tex](1.35695)^t = 4.6[/tex]

[tex]\log{(1.35695)^t} = \log{4.6}[/tex]

[tex]t\log{1.35695} = \log{4.6}[/tex]

[tex]t = \frac{\log{4.6}}{\log{1.35695}}[/tex]

[tex]t = 5[/tex]

So the correct answer is 5 trials, option C.

Explanation:

An estuary is where a river pours into the ocean. So that means fresh water mixes with salt water here. This allows us to rule out choices A and B.

According to NOAA, their site says "Estuaries are one of the most productive ecosystems in the world, so there is a great diversity of animals and plants that live there". In other words, a lot of plants and animals live here, so we can rule out choice C.

Choice D is the answer because tides do affect estuaries. This is simply because the ocean is pretty much right next to it, or attached to it. So it's expected that a high tide would cause the water level in an estuary to increase.

Answer:

it is affected by tides that's the conclusion I have come to

Step-by-step explanation:

1.Go to home

2.Plug in the computer

3. Play all trigger games

400 cupcakes in total

200 would be vanilla

so 100 would be chocolate and the remaining 100 should be funfetti

A: 100

Answer:

1/2x - 1/4 * 5x^2 - 2x + 6 = 116/4 = 29

A. Work : 1/2x = 2/4x - 1/4 = 1/4x

5x^2 = 25 - 2x = 23x + 6 = 29x

1/4x * 29x = 1/4x * 116/4x = 116/4x = 29

B. 1/4x - 1/2 * 5x2 - 2x + 6 = -29

No, it is not equal to the product up above

Because  its basically the same thing but the 1/2 and 1/4x

are switched which makes it negative

Hope it helps

Answer:

1. is 29.3in^3

Step-by-step explanation:

Since after 8 minutes it wasn't cooked enough he put it in for more time. So that means the arrow should be pointing to more time. But the circle isn't filled in because it is more than 8 minutes.

Answer:

m= 17.4

Step-by-step explanation:

Answer:

Solution given:

A triangle PQR is right angled at R, with hypotenuse{h}PQ=80cm

and

base[b]PR=60cm.

perpendicular [P]= QR

by using Pythagoras law

h²=p²+b²

80²=QR²+60²

QR²=80²-60²

QR=[tex]\sqrt{2800}[/tex]

QR=20[tex]\sqrt{7}[/tex]=52.9=53cm

QR=53cm.

Answer:

1.632 ft cubic

Step-by-step explanation:
