Answer:
D
Step-by-step explanation:
The formula for the area of a segment is ...
A = 1/2r²(θ -sin(θ))
for radius r and central angle θ.
Here, we have θ = π/2, so this becomes ...
A = 1/2r²(π/2 -1) . . . . . matches choice D
Answer:
90%
90% of the teas were caffeinated.
Step-by-step explanation:
Total teas: 63+7= 70
63/70 x 100/1= 90%
90% of the teas were caffeinated.
Answer:
The calculated dollar-weighted rate of return, Y = -25%.
Step-by-step explanation:
The time-weighted rate of return is 0%
Therefore, (12/10)*( X/(12 + X)) = 1
12X = 120 + 10X -> X = 60
The dollar-weighted rate of return,Y is calculated below as:
Y = (X-(10 + X))/(1*10+X/2)
Y = (60-(10+60))/(1*10+60/2)
Y = (60 - 70)/(10+30)
Y= -10/40
Y = -25%
Therefore, the calculated dollar-weighted rate of return, Y = -25%.
Answer:
10
Step-by-step explanation:
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 :)
