If one looks at red numbers on the chart specifying grade, one can see the quirkiness of using the grade to specify slope; the numbers go from 0 for flat, to 100% at 45 degrees, to infinity as it approaches vertical. Slope may still be expressed when the horizontal run is not known: the rise can be divided by the hypotenuse (the slope length).
If a student in grade 8 or below takes Algebra I, Geometry, or Algebra II before grade 9, the student must take the respective end-of-course STAAR assessment as well as the standard STAAR tests given, but it is up to the school districts to determine if the student should take the STAAR Mathematics test or not; it is completely optional in this ...
[18] [19] Today, the degree, 1 / 360 of a turn, or the mathematically more convenient radian, 1 / 2 π of a turn (used in the SI system of units) is generally used instead. In the 1970s – 1990s, most scientific calculators offered the gon (gradian), as well as radians and degrees, for their trigonometric functions . [ 23 ]
An inclination of 63.4° is often called a critical inclination, when describing artificial satellites orbiting the Earth, because they have zero apogee drift. [3] An inclination of exactly 90° is a polar orbit, in which the spacecraft passes over the poles of the planet. An inclination greater than 90° and less than 180° is a retrograde orbit.
Elevation is 90 degrees (= π / 2 radians) minus inclination. Thus, if the inclination is 60 degrees (= π / 3 radians), then the elevation is 30 degrees (= π / 6 radians). In linear algebra, the vector from the origin O to the point P is often called the position vector of P.
A graph shows increases in reading MAP scores for Fort Worth ISD students in kindergarten through eighth grade, comparing beginning of the year scores to middle of the year scores.

The agency used a computer program to grade short written answers for students who took the STAAR in December, when usually only high school level tests are offered, said Jose Rios, director of ...
