Which graphs have rotational symmetry? Check all of the boxes that apply.
ivanzaharov [21]

Answer:

The correct option are;

On a coordinate plane, a cubic function has an x-intercept of (0, 0)

On a coordinate plane, an oval is in quadrant 1

Step-by-step explanation:

Rotational symmetry of a shape is a shape that when it is rotated on its axis to a given angle less than one complete revolution, the shape looks exactly like the pre-image or original appearance of the shape

For a cubic function that has x-intercept = (0, 0) we have;

y = f(x) = a·x³ + b·x² + c·x

Has the shape f a fan blade and therefore, looks the sane when rotated when rotated through 180°

The shape of an oval looks the same when rotated through 180°

What is the area of the given composite figure, using 3.14 for π. Round to the nearest tenth. (*Hint- find the area of the recta
Illusion [34]

The area of the rectangular part = 14 x 20 = 280 sq. cm

The area of the half circle = 1/2 (3.14 x 7^2) = 76.9 sq. cm.


Total area = 280 + 76.93 = 356.9 cm^2

What function is represented by a line with slope -2 that passes through the point (0,4)
Helga [31]

We can write the function in slope-intercept form (y + mx + b). Since we have the slope, we can solve for the y-intercept.

y = -2x + b

4 = -2(0) + b

4 = b

Input the data we have now.

y = -2x + 4

Since we are dealing with a function switch out the y for f(x)

f(x) = -2x + 4

Best of Luck!
