A.) it has no reflectional symmetry

coldgirl [10]

Answer:

D.) It has rotational symmetry with an angle of rotation of 90 degrees.

Step-by-step explanation:

i) the shape shown in the figure has reflectional symmetry with four lines of symmetry. There are four lines of symmetry such that each line when drawn divides the shape into two exact halves such that if each half were too be folded across the line of symmetry it would produce the other half exactly.

Therefore Option A.) and Option B.) are not true

ii) It has point symmetry which means if the shape is rotated by 180 degrees the shape does not change. Therefore Option C.) is not true.

iii) the shape has rotational symmetry because if the shape is rotated though any between 0 degrees and 360 degrees the shape appears to be unchanged.

Therefore the correct options are

D.) It has rotational symmetry with an angle of rotation of 90 degrees.

A camera manufacturer spends $1,800 each day for overhead expenses plus $9 per camera for labor and materials . The cameras sell

kobusy [5.1K]

A) set x as the number of cameras
18x=9x+1800
9x=1800
x=200

b) i'm assuming it's increasing production from my answer in a, so the profit would be 18(250)-(9*250+1800)=4500-4050=450

Which graph represents the polynomial function g(x)=x3+x2−17x+15?

IrinaVladis [17]

The graph which represents the polynomial function g(x) is:

the 2nd graph in the second line

Step-by-step explanation:

g(x) = x³ + x² - 17x + 15 is a cubic function because the greatest power

of x is 3

All graphs represent cubic functions

So to find which graph which represents g(x) we will do these steps

1. Put x = 0 to find the y-intercept

2. If there are more than one graph have the same y-intercept we will

find the maximum and the minimum points of the cure

3. If you still don't know which graph find the x-intercepts

Now let us find the graph which represents g(x)

∵ g(x) = x³ + x² - 17x + 15

∵ x = 0

∴ g(0) = (0)³ + (0)² - 17(0) + 15

∴ g(0) = 15

∵ g(0) is the y-intercept

∴ The graph intersect the y-axis at point (0 , 15)

There is only one graph intersects y-axis at point (0 , 15)

The attached figure is the graph of g(x)

The graph which represents the polynomial function g(x) is:

the 2nd graph in the second line
