Answer:

7.2^2 = 51.84

51.84 x 3.14 = 162.7776(area of circle on bottom)

162.7776 x 17(height) = 2767.2192

2767.2192 divided by 3( x 1/3) = 922.4064

922.4064 rounded to the nearest hundredths place:

922.41 m3

Step-by-step explanation:

Formula of a cone:

base(area) x height x 1/3 (basically just dividing by 3)

If f(x)=3x5−10x3+5, on what intervals is f″(x)>0?

Ksivusya [100]

Answer:

$(0.7937,\infty)$

Step-by-step explanation:

we are given an algebraic function in x, such that

$f(x) = 3x^5-10x^3+5$

To find when second derivative >0

For this let us find first and second derivative by successive differentiation.

$f(x) = 3x^5-10x^3+5\\f'(x) =15x^4-30x^2\\f'(x)=60x^3-30$

when ii derivative >0 we have

60x^3-30>0

$x^3>0.5\\x>0.7937$

f"(x)>0 in

$(0.7937,\infty)$

What is the y-intercept of the function f(x) = –2/9x + 1/3?

marishachu [46]

<span>f(x) = –2/9x + 1/3
</span>y -intercept when x = 0
so
f(x) = –2/9(0) + 1/3 then f(x) = 1/3

answer
<span>y-intercept </span>(0, 1/3)

what is the distance between the points (4, 5) and (10, 13) on a coordinte plane a. 12 units b. 8 units c. 10 units d. 14 units

qaws [65]

Answer:

<h2>10 units</h2>

Option C is the correct option

Step-by-step explanation:

Let the points be A and B

A ( 4 , 5 ) ------> ( x1 , y1 )

B ( 10 , 13 ) ------> ( x2 , y2 )

Now, let's find the distance between these points:

$\sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} }$

plug the values

$= \: \sqrt{(10 - 4) ^{2} + {(13 - 5)}^{2} }$

Calculate the difference

$= \sqrt{ {(6)}^{2} + {(8)}^{2} }$

Evaluate the power

$= \sqrt{36 + 64}$

Add the numbers

$= \sqrt{100}$

Write the number in exponential form with. base of 10

$= \sqrt{ {(10)}^{2} }$

Reduce the index of the radical and exponent with 2

$= 10 \: units$

Hope this helps..

Best regards!!
