The answer is choice A) y = 2^x - 1
--------------------------------------------
Explanation:
Note how the curve goes through (0,0). So this means that plugging in x = 0 should lead to y = 0. Let's see which choices do that for us
choice A) y = 2^x - 1 = 2^0 - 1 = 1-1 = 0
choice B) y = 2^(x - 1) = 2^(0 - 1) = 2^(-1) = 0.5
choice C) y = 2^x + 1 = 2^0 + 1 = 1+1 = 2
choice D) y = 2^(x + 1) = 2^(0 + 1) = 2^1 = 2
Only choice A has x = 0 lead to y = 0, which is why choice A is the answer

Answer:
-∞ < y ≤ 12
Step-by-step explanation:
The range is the vertical extent of the graph of the function. Here the function values range from -∞ to a maximum of about 12. An appropriate description is ...
-∞ < y ≤ 12
Answer:
D. 36.56 cm²
Step-by-step explanation:
The composite figure is composed of a rectangle and two semicircles.
The two semicircles makes 1 full circle.
Thus:
Area of the composite figure = area of rectangle + area of circle
= L*W + πr²
L = 6 cm
W = 4 cm
r = ½(4) = 2 cm
Area = 6*4 + π*2²
Area = 24 + 12.56
Area = 36.56 cm²
Answer:
1161 confirmed cases
Step-by-step explanation:
In 2000 the number of cases was 86
Percent means out of a hundred, so if we divide 1350 by 100 we get 13.5.
So, we must multiply 13.5 and 86 to get the amount of cases in 2019.
13.5*86 = 1161 confirmed cases in 2019

-2x+24y+120=0 (Subtract 120 on both sides and rearrange)
-2x++24y=-120 (Then divide 2 by 2 and square it. Do the same for 24.)
-2x+1++24y+144=-120+1+144 (You have to add the same numbers on both sides)
(Simplify)
So you would put (1,-12); r=5
