Answer: The correct choices are D and F.

Step-by-step explanation:

There are two classifications of triangles shown.

Any triangle can only be two.

The first classification depends on the triangles' angles:

Acute triangles are triangles with three angles under 90 degrees.
Right triangles are triangles with a right angle.
Obtuse triangles are triangles with an obtuse angle.

The second classification depends on the triangles' sides:

Equilateral triangles are triangles with three equal side lengths.
Isosceles triangles are triangles with two equal side lengths.
Scalene triangles are triangles with no equal side lengths.

The triangle given has angles of 36, 54, and 90 degrees. 90 degrees is a right angle, so the triangle is a right triangle.

The triangle given has side lengths of 7, 5.1, and 8.66. No side lengths are equal, so the triangle is a scalene triangle.

The correct choices are D and F.

Don't mind the yt but how/?

Nuetrik [128]

r = 44

12 = r -(34-2)

12 = r -(32)

12 = r-32

r = 32+12

r = 44

For the given table of values for a polynomial function, where must the zeros of the function lie?

Jet001 [13]

Answer:

A. Between 3.0 and 3.5 and between 4.0 and 4.5

Step-by-step explanation:

The zeroes of a function occur whenever a value of x returns zero. To predict where the zeroes lie, determine the interval(s) where the function crosses the x-axis. This occurs when either $f(x)$ goes from a negative value to a positive value or vice versa.

From $x=3.0$ and $x=3.5$ , the y-values go from 4.0 (positive) to -0.2 (negative), respectively. Therefore, there must be a zero in this interval.

From $x=4.0$ and $x=4.5$ , the y-values go from -0.8 (negative) to 0.1 (positive), respectively. Therefore, there must also be a zero in this interval.
