2.6 feet per step. You divide 13 by five. the equation would be 5x=13. X=2.6

A child reshapes a cone made up of China clay of height 24 and radius 6 into a sphere.

grandymaker [24]

Answer:

Step-by-step explanation:

Volume of the cone = V=πr2h ^3=π·62·24 ^3≈904.77868

So, the volume of the sphere, will be the same too:

904.78 = 4/3 x pi x r^3

Solve:

904.78 = 4.18 x r^3

r^3 = 904.78 divided by 4.18

r^3 = 216.45

r = cube root of 216(approximate) = 6.

Hope this helps.

Good Luck

Tomás is using this recipe to make

Aloiza [94]

Step-by-step explanation:

For 2 people it uses 1 1/3 cups

1 1/3 = 1.33

So for 4 people Tomas will use

1 1/3 + 1 1/3 = 2.66 or 2 2/3 cups

Use the change-of-basis identity,

$\log_x(y) = \dfrac{\ln(y)}{\ln(x)}$

to write

$xyz = \log_a(bc) \log_b(ac) \log_c(ab) = \dfrac{\ln(bc) \ln(ac) \ln(ab)}{\ln(a) \ln(b) \ln(c)}$

Use the product-to-sum identity,

$\log_x(yz) = \log_x(y) + \log_x(z)$

to write

$xyz = \dfrac{(\ln(b) + \ln(c)) (\ln(a) + \ln(c)) (\ln(a) + \ln(b))}{\ln(a) \ln(b) \ln(c)}$

Redistribute the factors on the left side as

$xyz = \dfrac{\ln(b) + \ln(c)}{\ln(b)} \times \dfrac{\ln(a) + \ln(c)}{\ln(c)} \times \dfrac{\ln(a) + \ln(b)}{\ln(a)}$

and simplify to

$xyz = \left(1 + \dfrac{\ln(c)}{\ln(b)}\right) \left(1 + \dfrac{\ln(a)}{\ln(c)}\right) \left(1 + \dfrac{\ln(b)}{\ln(a)}\right)$

Now expand the right side:

$xyz = 1 + \dfrac{\ln(c)}{\ln(b)} + \dfrac{\ln(a)}{\ln(c)} + \dfrac{\ln(b)}{\ln(a)} \\\\ ~~~~~~~~~~~~+ \dfrac{\ln(c)\ln(a)}{\ln(b)\ln(c)} + \dfrac{\ln(c)\ln(b)}{\ln(b)\ln(a)} + \dfrac{\ln(a)\ln(b)}{\ln(c)\ln(a)} \\\\ ~~~~~~~~~~~~ + \dfrac{\ln(c)\ln(a)\ln(b)}{\ln(b)\ln(c)\ln(a)}$

Simplify and rewrite using the logarithm properties mentioned earlier.

$xyz = 1 + \dfrac{\ln(c)}{\ln(b)} + \dfrac{\ln(a)}{\ln(c)} + \dfrac{\ln(b)}{\ln(a)} + \dfrac{\ln(a)}{\ln(b)} + \dfrac{\ln(c)}{\ln(a)} + \dfrac{\ln(b)}{\ln(c)} + 1$

$xyz = 2 + \dfrac{\ln(c)+\ln(a)}{\ln(b)} + \dfrac{\ln(a)+\ln(b)}{\ln(c)} + \dfrac{\ln(b)+\ln(c)}{\ln(a)}$

$xyz = 2 + \dfrac{\ln(ac)}{\ln(b)} + \dfrac{\ln(ab)}{\ln(c)} + \dfrac{\ln(bc)}{\ln(a)}$

$xyz = 2 + \log_b(ac) + \log_c(ab) + \log_a(bc)$

$\implies \boxed{xyz = x + y + z + 2}$

Help, please this is my last question and i cant figure it out

allsm [11]

Hi! Your answer is y = x + 4

Please see an explanation for a better and clear understanding to your problem!

Any questions about my answer and explanation can be asked through comments! :)

Step-by-step explanation:

Here are the reasons why it's A choice which is y = x + 4.

The graph passes through y-axis at (0,4) which makes it obvious that the graph has y-intercept/b-value equal 4.
The graph has slope of 1. We can tell by rise over run (A glance can tell that the graph has slope of 1.)
Other choices have y-intercept at (0,0) also known as "origin point". The graph shown doesn't pass an origin point but passes through (0,4) as explained.

Here is the slope-intercept form, it might benefit you in some questions!

$\HUGE{y=mx+b}$

where m = slope and b = y-intercept.

Hope this helps! :)
