As scientists conduct their research, they make observations and collect data. The observations and data often lead them to ask why something is the way it is. Scientists pursue answers to these questions in order to continue with their research.
Answer:
Step-by-step explanation:
Example Equation of an ellipse with horizontal major axis with center at (0,0):
x%5E2%2Fa%5E2%2By%5E2%2Fb%5E2=1
For given problem:
b=20
b^2=400
a=30
a^2=900
equation: x%5E2%2F900%2By%5E2%2F400=1
y%5E2%2F400=1-x%5E2%2F900
Answer:
<h3>18</h3>
Step-by-step explanation:
From the given diagram;
FGH = 49
GH = 31
Using the expression to get FG;
FG + GH = FGH
FG + 31 = 49
FG = 49-31
FG = 18
Hence the measure of FG is 18
Answer:
-9
Step-by-step explanation:
-1y+11=20
-11= -11
-1y=20-11
-1y=9
-9
The answer is $8.75. You have to find what one costs which is 1.25 so if you have 7. 1.25 times 7 is $8.75
