Answer:
It's y = (5)(0.2)^x
_____________
Step-by-step explanation:
Exponential functions have a standard form of ab^x
Where a is the starting value, and b is the exponential growth or decay.
Because the numbers are getting smaller and smaller, it is a decay so b must be less than one.
We can eliminate the first choice because when x is 1, y is 1. If this where the equation we would get (5) (1/2) ^ 1 = 5 × 1/2 = 2.5 ≠ 1.
So the answer must be the second choice.
294/X= -14
Cross multiply
294= -14X
Divide both sides by -14
294 : -14 = -21
-14 gets cancelled out so the X is isolated
X= -21 or -21=X it doesn’t really matter which way you put it
Answer:
24
Step-by-step explanation:
gcf for that is 24 I think
No because 21 ft equals 7 yd
which us bigger than 3 yd
Answer:
No positive value of n
Step-by-step explanation:
we have to find out for how many positive values of n are both
our-digit integers
Let us consider first cube
we get 4digit lowest number is 1000 and it has cube root as 10.
Thus 10 is the least integer which satisfies four digits for cube.
The highest integer is 9999 and it has cube root as 21.54
or 21 the highest integer.
Considering 3^n we get,
3^10 is having 5 digits and also 3^21
Thus there is no positive value of n which satisfy that both n cube and 3 power n are four digits.
