Answer: (x^2)/16 + (y^2)/25 = 1
Step-by-step explanation:
According to the problem we can figure out that the center of the ellipse is (0,0).
Since the foci is (0,3) and (0,-3) we know that the value of c is 3. The major vertices are (0,5) and (0,-5) so the value of a is 5.
If we put this into the equation a^2=b^2 + c^2, we get 25=9+ b^2
We get b^2 is 16
Now since we know that the ellipse is vertical because the x value didn’t change, we know that the b^2 value comes first in the equation. Then the a^2 value which is 25.
Answer:
41.3° and 48.7°
Step-by-step explanation:
Complementary angles are angles with the sum of 90°
if one of the angle is 7.4° less than other
(90 - 7.4) ÷ 2 = 41.3° is the measure of smaller angle and
41.3 + 7.4 = 48.7° is the measure of bigger angle
Answer:
Step-by-step explanation:
600g of 20%
100 - 20 = 80
600 = 80%
/80%
7.5 = 1%
x100
750 = 100%

Sorry I don’t know what else to write. Hopefully, this guarantees you a mark.
The answer is 2.5 just set it up and cross multiply then divide
Answer:
28y^3 -35y^5
Step-by-step explanation:
= 7y^3(4) -7y^3(5y^2)
= 28y^3 -35y^5
