The given function is : y= f(x) =49 [\frac{1}{7}]^x
The statements which are true regarding this function is
1. As you can observe that y is defined for all values of x , so Domain is set of all values that x can take which is set of all real numbers.
2. Also, x =\frac {\log[\frac{y}{49}]}{-\log7}, so x is defined for all values of y. Range is all values that y can take which is also set of all real numbers greater than zero, i.e y>0.
As ,x =0 then y= 49 and x_{1} =1 then y_{1} = 7,
so ,y_{1} = \frac{y}{7}.
So, Option (1),(4) and (5) are correct.
So basically we can check them all by multiplying all of the dimensions.
A: 3 * 3 * 40 = 360, so yes, it could be the dimensions
B: 4 * 4 * 20 = 320, so no, it couldn't be the dimensions
C: 6 * 6 * 10 = 360, so yes, it could be the dimensions.
D: 2.5 * 12 * 12 = 360, so yes, it could be the dimensions.
E: 3.6 * 10 * 10 = 360, so yes, it could be the dimensions.
I hope this helped :)
Answer:
4/10
Step-by-step explanation:
when converting fractions, you multiply the numerator and the denominator by the same number. In this case, multiply it by 2, giving you 4/10.
Answer:
16 1/3 miles in one hour.
Step-by-step explanation:
12.25 miles in 45 minutes.
How far in 60 minutes?
Set up a proportion: 12.25/45=x/60
45x=735
x=16.3333...
Therefore, Manuel can go 16 1/3 miles in one hour.
I hope this helped and have a good rest of your day!
