Answer:
B. negative infinity < x < positive infinity
Step-by-step explanation:
When a question asks for the domain of a function, it is asking for all possible x-values, so we can rule out choice A since there are clearly x-values greater than 1. This graph shows arrows pointing left and downward, indicating that the graph continues past what we can see. This tells us that even though the x-values look like they end at -10 and 2, they continue further, so we can also rule out option C and option D. After these eliminations, we are left with choice B, which is a way of writing "All real numbers," and is the domain for <u>all</u> exponential functions, including this one.
lmk if im incorrect about anything, hope this helps :)

Answer:
A
Step-by-step explanation:
Note
One thing you should automatically notice is that x is larger, much larger than 20. x is the hypotenuse of a right triangle
Formula
Sin(18) = opposite side / hypotenuse
Givens
Sin(18) = 0.30902
opposite = 20
hypotenuse = x
Solution
sin(18) = 20 / x Multiply both sides by x
x sin(18) = 20*x /x
x sin(18) = 20 Divide by sin(18)
x sin(18) / sin18 = 20/sin(18)
x = 20 / 0.30902
answer: x = 64.72
Answer:
EF=8 FG=15
Step-by-step explanation:
EF+FG=EG
2x-12 + 3x-15 =23
5x-27 =23
5x=50
x=10
<em>Plug In:</em>
EF=8
FG=15
