They would be like terms because as you can see, there is only 1 difference. In the expression 3z^2 and 2z^2 the only difference is that the first two numbers are different.
Answer:
It C - S = 1520
Step-by-step explanation:
The way i founded it out was
r = 1369/1521 ≈ 0.90 these the common ratio
So, the sum is ...
S = 1521/(1 -r) = 1521/0.10 = 15,210 . . . . . sum of the series
Answer: 93 degrees
Step-by-step explanation: The 3 angles of a triangle always add up to 180. Two angles are 87 and to find the third angle, you subtract 180 by 87 and get your third angle which is 93.
Maurice wants to create a set of elliptical flower beds. To do this, he first plots the location of the two fruit trees on his graph.
Maurice has to use the equation a^2-b^2=c^2. We know that c=3, and because we need 1 more number to solve for b, I made a=6. 6^2-b^2=3^2. 36-b^2=9. b^2=27. b=5.196
<span>Next, to create the equation, we substitute what we know into the equation x^2/a^2 + y^2/b^2=1 and get x^2/36 + y^2/27=1. Johanna wants to create some hyperbolic flower beds.
We already know that c=3 so this time I decided a=1. 3^2=1^2+b^2. 9=1+b^2. 8=b^2. b=2.828
Next, to create the equation, we substitute what we know to the equation x^2/a^2 - y^2/b^2 = 1. x^2/1^2 - y^2/2.828^2 = 1. </span>
