Answer: The length of an arc is simply the length of its "portion" of the circumference. The circumference itself can be considered a full circle arc length. Arc Measure: In a circle, the degree measure of an arc is equal to the measure of the central angle that intercepts the arc.
Step-by-step explanation:
Answer:
(0,6), (0,4), (0,-10)
Step-by-step explanation:
3x-6y=2 (label equation 1)
5x+4y=1 (label equation 2)
-6y=-3x+2 (rearranged equation 1)
y=1/2x-1/3 (label equation 3)
substitute equation 3 into equation 2
5x+4(1/2x-1/3)=1
5x+2x-4/3=1
15x+6x-4=3 (multiplied everything by 3)
21x-4=3
+4 +4
21x=7
x= 7/21
x=1/3
sub x=7/21 into equation 3
y= 1/2(1/3) -1/3
y= -1/6
Therefore x=1/3 and y= -1/6
Answer:
24
Step-by-step explanation:
From the picture you can see that area is sume of area P1 and area P2.
a=6 because its egdes are on point -2 and 4, so it is 6. (See x-ose)
h=3 Edges on -2 and 1 (see y-ose)
k=2 edges on 3 and 1 on y-ose
P1=a*h=6*3=18
P2=a*k/2=6*2/2=6
P=18+6=24
Based on the information given, the explanatory variable will be the SAT prep program and the response variable is the student's scores.
<h3>
Identification of the variables.</h3>
The information given is that the researcher conducts an experiment to investigate whether an SAT prep program would improve students' scores on the SAT.
The explanatory variable is the factor that is manipulated by the researcher. The response variable is the result of the experiment.
In this case, the explanatory variable is the SAT prep program and the response variable is the student's scores.
In this case, the treatment will be the 120 students that took part in the research. They're the ones that are exposed to manipulation by the researcher.
