Answer:
A
Step-by-step explanation:
An exponential function has the form
y = a
Use the given solutions to find a and b
Using (0, 3 ) , then
3 = a
[ = 1 ] , so
a = 3
y = 3
Using (1, 12 ) , then
12 = 3
= 3b ( divide both sides by 3 )
4 = b , then
h(x) = 3
→ A
Answer:
what are the options? the answer I got was a fraction 19/4
2/7=0.2857142857
1/3=0.3333
A rational number is that number that can be expressed as a ratio of 2 integers.
The 5 numbers could be:
0.29=29/100
0.3=3/10
0.31=31/100
0.32=32/100=8/25
0.33=33/100
These numbers are not unique.
a)
A = 5m × 7m = 35 m²
b)
A = 4cm×8cm/2 = 4cm×4cm = 16 cm²
c)
A = 1,2km×0,8km/2 = 0,96km²/2 = 0,48 km²
d)
A = (8m + 10m)·3m/2 = 18m·3m/2 = 9m·3m = 27 m²
X = 9 is the correct answer
