unless the formula is equal to something, the only thing you can know is that it simplifies to x^2 + 4x + 4

43.58 is 43.576 rounded to the nearest hundredth.

Simple: just plug in the values.

f(0)=3(0)-4=-4

f(1.5)=3(1.5)-4=0.5

f(-4)=3(-4)-4=-16

The surface area = the sum of the areas of all of the sides.

But you already knew that, I'll bet?

f(4) = 5 + √x  =   5 + √4  =  5 + 2 = 7

Janel is 8  and Stephanie is (5/4) of this = 10

And we want to solve this......

(13/12)(8 + x)  =  (10 + x)     where x is the number of years......simplify

(26/3) + (13/12)x  = 10 + x      multiply through by 12

104 + 13x  = 120 + 12x     

x = 16 years

Check ....in 16 years, Janel will be 24 and Stephanie will be 26......so .....Janel will be 12/13 as old as Stephanie.....

Since ABCD is inscribed in a circle, A + C = 180°, and B + D = 180°.

So, 64 + 9x - 1 = 180 => x = 13 => D = 98°.

( -50x)² = 2500 x²

(

to get -50x^2, you must square the whole equation. Therefore, it would then be -50*-50=2500. x^2= x^2. The new equation is now 2500*(x^2). 

My pet turtle can move faster than that!

m = -1/5     and we have the point (0, 5).....so we have

y - 5  = (-1/5)x   add 5 to both sides

y = (-1/5)x + 5      multiply throgh by -5

-5y = x - 25     rearrange

x + 5y  = 25

x + 5y - 25 = 0

0

Since $${{\mathtt{0}}}^{{\mathtt{2}}} = {\mathtt{0}}$$

$${\sqrt{{\mathtt{0}}}} = {\mathtt{0}}$$

QED

Answer Choices:

If both sides of a square is 8cm then the area is 64cm

8*8

If the total is 25cm^2 = 625

Each side is 25 

25*25

a=angle

h=hypotenuse

m=the height

sin(a)=m/h  -------->m=h*sin(a)

Good luck!

I don´t get it:/

Do you need to use all four operations (times, divide....) and all numbers?

$${\mathtt{V}} = {\frac{\left({\mathtt{\pi}}{\mathtt{\,\times\,}}{{\mathtt{r}}}^{{\mathtt{2}}}{\mathtt{\,\times\,}}{\mathtt{h}}\right)}{{\mathtt{3}}}}$$

r=radiús

h=height

you can write everything in seconds as well.

1h=60*60sek=3600sek

1min=60sek

so 1:32:20=1*3600+32*60+20=5540sek

1:44:30=1*3600+44*60+30=6270sek

in total 5540+6270=11810sek

then you go backwars and figure out how many whole ours you got and then minutes and the seconds.

you can also switch the numbers into sexagesimal numbers but that seems a bit overkill in this case.

Try this:

first you add the hours. ---> 1+1=2

now add the minutes ---> 32+44=76 min (60 min in one hour gives us 76= 1hour +16 min)

now we can add the seconds---> 30+20=50 (not a whole minute)

in total: 2h+1h+16min+50 sek

3:16:50

$$V=(pi*r^2*h)/3$$

$$V=(pi*(30/2)^2*36)/3=8482.3$$
