Answer: Domain is All Real Numbers, x = {1, -1}
<u>Step-by-step explanation:</u>
log₄² (1 + x²) = 0.25 restriction: 1 + x² ≥ 0 ⇒ x² ≥ -1 ⇒ x = ARN
log₄ (1 + x²) = 0.05
(1 + x²) = 4¹⁾²
1 + x² = 2
x² = 1
x = √1
x = +/- 1
It’s 25.12. The inches around is basically circumference. The formula for the circumference of a circle is pi times diameter. Your diameter is 8 inches multiplied by pi (3.14) is 25.12.
I'd love to help, however. You didn't list anything that needs to be solved! :P
Answer:
0.004
Step-by-step explanation:
Answer:
38°
Step-by-step explanation:
a whole circle is equal to 360 degrees so if 52 +90= 142 the opposite side also equals 142 because they are clearly the same size. ED and AB are also the same sizes. if 360- (142+142) = 284. then you will have to divide 284 by 2. so 284÷2=76 and 76÷2=38°
hope you understand, I not that good at explaining things
also I don't know what the m means in mED
