So the radian is the measure of how close a degree is to a complete circle. * How do special right triangles directly relate to the unit circle? There are two types of special right triangle, 90, 60, 30 and 45, 45, 90. With both triangles, the angles of degrees are directly related to the x and y values on the unit circle. With the case of 90, 60, 30 and 90, 45, 45, the angles are relative to the sin of its value on the unit circle.
1.explain what a radian measure represents using the unit circle as a reference. -A radian measure on a unit circle is the measure of the length of the arc at certain points on the unit circle. 2.how do special right triangles directly relate to a unit circle. -On the unit circle the radius of the circle is also the hypotenuse. therefore if you set the hypotenuse to be a value such as 1. the side (x,y) of the triangle will be the sine and cosine values on the unit circle.
Math 0960_WC M6 WPS Activity Page 1 of 2 | Using the attachment at the bottom of this page or using the textbox at the bottom of this page submit response to the following questions. Please write the questions out in a different color above your answers.Your text shows the rules for exponents on page 238. In this activity you will be asked to summarize SOME of these rules in words. (As if you were explaining them to someone over the phone.) I will start this activity by doing the first rule for you then you will write an explanation for the remaining 6 rules:1.
We can conclude that the data are Poisson distributed. Chi-Square test of independence Problem 12.12 Use the following contingency table to determine whether variable 1 is independent of variable 2. Let α = .01 | Variable 2 | Variable1 | 24 | 13 | 47 | 58 | | 93 | 59 | 187 | 244 | Step 1 Ho: the two classifications are independent Ha: the two classifications are dependent Step 2 d.f = (r – 1) (c – 1) Step 3 α = 0.01 x 2 0.01, 3df = 11.3449 Step 4 Reject Ho if x 2 > 11.3449 | Variable 2 | Total | Variable1 | 24 (22.92) | 13 (14.10) | 47 (45.83) | 58 (59.15) | 142 | | 93 (94.08) | 59 (57.90) | 187 (188.17) | 244 (242.85) | 583

4) Classify cyclopentadienyl cation as aromatic, antiaromatic, or nonaromatic. Assume planarity of the π network. The cyclopentadienyl cation is anti-aromatic with 4n pi electrons. 5) Provide the structure of the major organic product which results when phenanthrene is treated with Br2 in carbon tetrachloride. [pic] 6) Provide an acceptable name for the compound below.
D=m/v 4. What two sets of units can be used to describe density? Why are they interchangeable? The two sets of units used to describe density are grams (g) and milliliters (mL). They are interchangeable because 1g=1mL.
