Well what exactly do you need help with?
Answer:
The correct answer is option B. 65
Step-by-step explanation:
<u>To find the measure of <VYX</u>
Central angle of arc VW = 44°
Therefore m<VXY = 44/2 = 22°
And central angle of arc XZ = 86° therefore <XVY = 86/2 = 43
<u>To find the mesure of <XYZ</u>
m<XYZ = m<VXY + m<XVY
= 22 + 43
= 65°
Therefore the correct answer is option B. 65°
Answer:
slope = 3/5
Step-by-step explanation:
slope = rise/run = 3/5
or (longer way w/ the points)
slope = (y2-y1)/(x2-x1) = (5-2)/(4-(-1)) = 3/5
Answer:
S(t) = 600*0.9^t
Step-by-step explanation:
At the beginning (t = 0) the sample has 600 grams. After 1 millennium from today (t = 1) the mass will be: 600 - 600*0.1 = 600*0.9. After 2 millennium from today (t = 2) the mass will be the 90% of the mass in the previous millenium, that is: 600*0.9*0.9 = 600*0.9^2. Analogously, at time = 3, sample's mass will be: 600*0.9^2*0.9 = 600*0.9^3. In a table format, that is
t m
0 600
1 600 - 600*0.1 = 600*0.9
2 600*0.9*0.9 = 600*0.9^2
3 600*0.9^2*0.9 = 600*0.9^3
Therefore, sample's mass in grams, S(t), where t refers to millennia from today is computed as follows: S(t) = 600*0.9^t
Step-by-step explanation:
1=78°
3= 78°
4= 360°- 78° - 78°
= 204° ÷ 2
= 102°
2= 102°
Note that 1+2+3+4=360°
180° - (4)
= 180° - 102°
= 78° ÷ 2
= 39°
ans; angle ACD is 39°
