Answer:

The circumference is 56.52 m

Step-by-step explanation:

Eugene likely made the mistake of doubling the diameter thinking that it was the radius which gave the answer double the actual one. The equation for finding a circumference is C=\piD where d is equal to the diameter and c is the circumference. All you do is multiply 18 and 3.14 to get your answer.

Determine if the graph is symmetric about the x-axis, the y-axis, or the origin.<br> r = 9 sin 7θ
boyakko [2]

Answer:

The given function symmetric about the y-axis.

Step-by-step explanation:

The given function is

r=9\sin 7\theta                .... (1)

1. Symmetry about the x-axis: If the point (r, θ ) lies on the graph, then the point  (r,-θ ) or (-r, π - θ ) also lies on the graph.

2. Symmetry about the y-axis: If the point (r, θ ) lies on the graph, then the point (r,π - θ ) or (-r, -θ ) also lies on the graph.

3. Symmetry about the origin: If the point (r, θ ) lies on the graph, then the point (-r, θ ) or (r, π + θ ) also lies on the graph.

Put (r, -θ ) in the given function.

r=9\sin 7(-\theta)=-9\sin 7\theta=-r\neq r

Therefore it is not symmetric about x-axis.

Put (-r, -θ ) in the given function.

-r=9\sin 7(-\theta)=-9\sin 7\theta=-r

Therefore it is symmetric about y-axis.

Put (-r,θ ) in the given function.

-r=9\sin 7(\theta)=r\neq -r

Therefore it is not symmetric about the origin.

PLSSS HELPPPP I WILLL GIVE YOU BRAINLIEST!!!!!!
jenyasd209 [6]

Answer:

x= -1/3

y= -3 1/3

Step-by-step explanation:

Make both of them into y=Mx+b form

y=-x-3

y=(-x-7)/2

Substitute the x-3 in the first equation for the y in the second one.

x-3=(-x-7)/2

2x-6=-x-7

3x=-1

x=-1/3

Now that we have x, we can solve for y.

y=-x-3

y=-1/3-3

y=-3 1/3

Divide using synthetic division: (2x^4+2x^3+-12x^2+x+6)/(x+3)​
kap26 [50]

Synthetic division yields

..... ||   2    2   -12    1      6  

-3  ||        -6    12    0    -3

= = = = = = = = = = = = = =

..... ||   2   -4     0    1      3

which translates to

\dfrac{2x^4+2x^3-12x^2+x+6}{x+3}=2x^3-4x^2+1+\dfrac3{x+3}

I need advice on this answer not good at math​
Temka [501]

Answer:

A rational number is defined as a number that can be written as a fraction and a number that terminates.

An irrational number is defined as a number that can't be written as a fraction and a number that has no end.

Step-by-step explanation:

4/7 is irrational because, in decimal form, it is 0.57142857...

Square root of 30 is also irrational because the square root is 5.47722557...

21 divided by square root of 4 is rational because square root of 4 is 2 and 21 divided 2 is 10.5.

pi is irrational because, in decimal form, it is 3.14159265....

-27 is also rational because it terminates
