Answer:
I think its 187 years
Step-by-step explanation:
Hope this helps!!
The standard equation of the circle is:
(x-h)^2+(y-k)^2=r^2 where (h,k) it the center of the circle and r is the radius...
so
30.
(x-2)^2+(y-7)^2=16
31.
We need to find the radius...(I'll just use the Pythagorean Theorem)
r^2=6^2+8^2
r^2=36+64
r^2=100 (so the radius is 10) and its center is (-6,-8) so
(x+6)^2+(y+8)^2=100
The answer is
<span>F. Square both sides
</span><span>D. Subtract 4 from both sides
</span><span>C. Divide by 6 from both sides
</span>
√(6x +4) = 8
Square both sides:
(√(6x +4))² = 8²
6x + 4 = 64
Subtract 4 from both sides
6x + 4 - 4 = 64 - 4
6x = 60
Divide by 6 from both sides
6x/6 = 60/6
x = 10
Answer:3x^2-5x=-8 is the one that has 2 complex solutions
Step-by-step explanation:
Answer: D (-∞, ³⁄₂)
1. Find non - negative values for radicals. x ≤ ³⁄₂
2. Find undefined (singularity) points. x = ³⁄₂
3. Combine real regions and undefined points for final domain.
Final answer: x < ³⁄₂
