Answer:
B (second graph from left)
Step-by-step explanation:
The function when x=0 will be 1 since any number to the zero exponent is 1. This means only B and D are options.
Because of the fraction, the values will be smaller and have a gentler slope. B is the solution.
The length of the floor increased by 30% would be 33x1.30 = 42.9 feet.
The scale is 1 cm = 6 feet.
The drawing would be:
42.9 / 6 = 7.15 cm long
The answer is C.
<span>This problem is an
example of ratio and proportion. A ratio is a comparison between two different
things. For 3:8, it does not coincide with the ratio 40:15. If we try to
multiply 3 by 13, it would not reach 40. Same thing goes for 8 multiplied by
13. For 8:3, if we try to multiply 8 by 5 we would get 40. If we also multiply
3 by 5 we would get 15. Therefore b. is proportional to 40:15. For 90:240, if
we multiply 40 by 2, we would not get 90, also in 15, we would ot get 240. For 120:45,
if we multiply 40 by 3 we get 120. Also, if we multiply 15 by 3 we would get
45. Therefore, d is also proportional to 40:15.</span>
7. 2/9 + 7/9 is 9/9 which is 1.
4+2+1 is 7.
