< = angles
<a = 145
<b = 35
<c = 145
<d = 145
<e = 35
<g = 35
<f = 145
hope this helps
(x^2)/a^2+(y^2)/b^2=1
a>b
a=6, a^2=36
foci=(a^2-b^2)^(1/2)
4=(36-b^2)^(1/2)
16=36-b^2
b^2=36-16
b^2=20
b=2(5)^(1/2) or (20)^(1/2)
1=(x^2/36)+(y^2/20)
Answer:
The answer is 6.8
Step-by-step explanation:
Check on your calculator 6.8^2 equals 46
Answer:
Yes
Step-by-step explanation:
using distributive properties,
(3x+1)(4x-5) = 3x(4x-5) + 1(4x-5)
=> 12x^2 - 15x +4x - 5
=> 12x^2 - 11x - 5
(X-2)^2+(y-4)=2.25
Standard form is (x-h)^2+(x-k)^2=r^2
