X is the gcf so:

this is the maximum you can factor that too:

$\sf{x(9x^2-16)}$

A cone has a radius of 5 ft and a height of 15 ft. It is empty and is being filled with water at a constant rate of 15 15 ft 3 f

kvasek [131]

Answer:

$\frac{dr}{dt}=0.11062ft/sec$

Step-by-step explanation:

From the question we are told that:

Radius $r=5ft$

Height $H=15ft$

Rate $R=15ft/3sec =5ft/s$

Surface Radius $R_{surf}=2.2ft$

Generally the equation for Volume is mathematically given by

$V=\frac{1}{3}\pi*r^2h$

Since radius to height ratio gives

$\frac{r}{h}=\frac{5}{15}$

$\frac{r}{h}=\frac{1}{3}$

$h=3r$

Therefore

$V=\frac{1}{3}\pi*r^2(3r)$

$V=\pi r^3$

Generally the equation for Change of Volume is mathematically given by

$\frac{dv}{dt}=\pi \frac{d}{dt}(r^3)$

$\frac{dv}{dt}=\pi 3*r^2 \frac{dr}{dt}$

$\frac{dv}{dt}=\pi 3*(2.2)^2 \frac{dr}{dt}$

$\frac{dr}{dt}=\frac{5}{45.62}$

$\frac{dr}{dt}=0.11062ft/sec$

Goryan [66]

Answer:

30%
Unlikely

Step-by-step explanation:

<u>The balls - multiples of 3 are:</u>

3, 6 and 9

<u>The probability of a multiple of 3 is:</u>

3 out of 10 or
P = 3/10 = 30%

30% probability is in the range 0%-50% so this event is unlikely

Please help me! I’m begging you I’ll mark you brainly! I need it by now

Inessa05 [86]

Answer:

Boxes at the top are as follows

Monomial. 1. 4x

Binomial. 2. 4x+2

Trinomial. 3.

Polynomial. More than 3.

${5x}^{4} + {2x}^{3} + {12x}^{2} + 135$

This would be an example of a polynomial ^

Omit the next highest term to get a trinomial etc

1. 4th degree. Leading term:

${x}^{4}$

Leading coefficient: x

2. 2nd degree. Leading term:

$- {7x}^{2}$

Leading coefficient: -7x

It's a little confusing to read but that should be everything. Sorry it's not organized better
