Given the equation below, find the x and y−intercepts by completing the table.What is the problem with using these intercepts to

kvasek [131]

$-4x+2y=0$

In order to find the x-intercept we need to make y=0

$-4x+2(0)=0$

Then we isolate the x

$-4x=0$ $x=0$

x y Ordered Pair type of intercept

0 0 (0,0) x-intercept

Now for the y-intercept we need to make x=0

$-4(0)+2y=0$

we isolate the y

$2y=0$

$y=0$

0 0 (0,0) y-intercept

ANSWER

0 0 (0,0) x-intercept

A copy machine repairman makes $12.50 per hour plus $4 for every service call he performs. Last week he worked 34 hours and made

Slav-nsk [51]

Hours = 34 Income per hour = 12.5$ Service calls = 6 Income per call = 4 Therefore, total income = (time of working * income per hour) + (service calls * income per call) = (34*12.5) + (6*4) = 425+24 = 449

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

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

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

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

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

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