First of all let’s solve the exponent.
10 squared to the power of -2 would be 0.01. Now multiply 0.01 times 6.8 which will give you 0.068.

Find the volume of the cone in cubic feet. Use 3.14 for it and round your answer to the nearest tenth.

kenny6666 [7]

$\quad\hookrightarrow\quad \sf {5,790,806.5\:ft^3 }$

<h3>Ⲋⲟⳑⳙⲧⳕⲟⲛ:</h3>

Here, we area provided a cone with:

Radius = 48m
Height = 68 m

We have to find the volume of the cone in feet³, and we are given that 1m = 3.2808ft

<h3>Ⳙ⳽ⲓⲛⳋ ⳨ⲟⲅⲙⳙⳑɑ:</h3>

The volume of a cone is equal to one third of the volume of a cylinder having the same base radius and height ,i.e:

$\quad\longrightarrow\quad \sf { V =\dfrac{1}{3}\pi r^2 h }$

Therefore, Volume:

$\implies\quad \tt {V = \dfrac{1}{3}\pi r^2 h }$

$\implies\quad \tt { V =\dfrac{1}{3}\times 3.14 \times 48^2 \times 68 }$

$\implies\quad \tt { V =\dfrac{1}{\cancel{3}}\times 3.14\times \cancel{2304} \times 68}$

$\implies\quad \tt {V =3.14\times 768\times 68 }$

$\implies\quad \tt {V = 163,983.36}$

$\implies\quad \tt { V = 163,983.36 \times (3.2808)^3 \qquad\quad\bigg[ As, \: 1m = 3.2808ft\bigg]}$

$\implies\quad \tt {V = 163,983.36\times 35.30 }$

$\implies\quad\underline{\pmb{ \tt { V = 5,790,806.5 ft^3}}}$

‎ㅤ‎ㅤ‎ㅤ~Hence, the volume of given cone is 5,790,806.5 ft³.

3.1.3 How far was the hiker at 10:30?

umka21 [38]

Answer:

$y = 1400 + 5.2x$ --- Running cost

$y = 25 x$ --- Monthly income

71 cars

R1775

Step-by-step explanation:

Given

Expenses

$Salaries = 1400.00$

$Others = 5.20$ per car

Income

$Rate = 25.00$ per car

Solving (a): Expression for the running cost

This is calculated as:

$y = Salary + Others * x$

Where

y = Total running cost

x = number of cars

So:

$y = 1400 + 5.20 * x$

$y = 1400 + 5.2x$

Solving (b): Expression for monthly income

This is calculated as:

$y = Rate * x$

Where

y = Total income

x = number of cars

So:

$y = 25.00 * x$

$y = 25 x$

Solving (c): Break even

To do this, we equate the expressions in (a) and (b)

$y = y$

$25x = 1400 + 5.2x$

Collect Like Terms

$25x -5.2x= 1400$

$19.8x= 1400$

Solve for x

$x = \frac{1400}{19.8}$

$x = 71$

Solving (d): How much to break even

Substitute 71 for x in any of (a) or (b)

$y = 25 x$

$y = 25 * 71$

$y = 1775$

Solving (e): There is no question to answer on the "graph"

What is the end behavior of A(x)=(x+3)(x-4)(3x-7)(4x-3)

OleMash [197]

Answer:

Step-by-step explanation:

Since the highest power is x^4, y increases without bound as x approaches positive or negative infinity. So the end behavior is positive infinity.
