Round to the nearest tenth if necessary

Mathematics
1 answer:
GREYUIT [131]3 years ago

Answer:

Step-by-step explanation:

a=30

b= 17

c= 18

we actually already found angles B and C for the last problem I think we said 30 and 32 so we would be able to guess that angle A is about 118° but.. let's do the math... and see

angle A = arcCos[ b^2 + c^2 - a^2 / 2*b* c ]

A = arcCos[ 289 +324 - 900 / 2*17*18]

A = arcCos[ -287 / 612 ]

A = arcCos[ -0.468954 ]

A = 117.9664 °

ohh and we're off by 0.0336   phooy  :P soo far off... :P

rounding to nearest 10th

A = 118.0 °  ( ohh right on the money  :P)  yay, I feel better.  :P

Answer:

A. √32y²/72x²= 32y/72x

Step-by-step explanation:

√32y²/72x²= 32²/72²

= 32/72.

B. √125m³/36m²

=4192.6/108

=38.8203.

C. √x²/y²-y²/x²

therefore, x²=1, y²=-1

that is, √1/-1 - -1/1= -1(-)-1=0.

A=2x+6xz <br> a=2x+6xz<br> for x
Dennis_Churaev [7]
So I guess we are solving for x here :)
So here is my work...
a=2x+6xz
Basically I think it would be
a=6xz+2x

WAIT WAIT NO I'M WRONG FORGIVE ME!

It's  x=a/2(1+3z)

Answer:

1.  The y values are decreasing by 16  7 and 4 then rising by 7 and 16 so the line of symmetry is at -4 or 4

2. f = g(x) function just like g = f(x) function so say f value table or g(x) function

3.  y = g(x) = -4  when x = 0

4.  y - 0 = - 4x   means the same as y = -4x

5.  [0 , -4] is the vertex

6.  6(5) = 30

next page

7 the y values are increasing by 3/4 , 11/5, 1,  7/1 and  8.5 / 1

which means thy are increasing minimum by 1/1.5 and could be a square function.

8. This is a g function or  a f(x).

9. y intercept is 1

10  common ratio is  0:1

11 equation for the table is  y = x -1

12.  5.400

next page

13.

The values for y are decreasing by 2 then drop by 12 from -2/14 to 0/-2 then increase again at a rate of 20 and decrease slightly to 18 being  -2/-20

we can see this as -2/16 ,-2/14 , 0/-2  2/ -22 meaning the line of symmetry is not clear as we cannot see an average without working out the mean or adding all the totals up.

14.  p(x) function or q value.

15.  the y intercept is -2

16. the equation for this table is y = x-2

17.

The value for p(4) is same method divide smaller into larger then times x 4

-20/-2 = 10  

then -11 x 10 = -110

18. slope = -2

17) if they were asking for value for 4(p) is  16/ -2 = 8 and  -2 / 4  = 0.5/ 8 this shows 8 so 4 is half this value = 0.24 / 4  meaning x = 0.24
