Answer:
C
Step-by-step explanation:
3-2a<7
= -2a<7-3
=-2a<4
=-2a/-2<4\-2
=a<-2
None of the factors shown will give you the above number. In order to get the numbers that are on top, you would need two x's being multiplied by each other to get the x^2 value. Since none of the options have that, it is impossible to achieve that.
We are given points (30,4) , (60,8) and (90,12)
To calculate the rate per minute at which the air freshener dispenses sprays,
we can use two points to find slope.
The formula for slope is given by :
let us use two points (60,8) and (90,12) to find the slope,
Slope = 4/30
So the rate per minute at which the air freshener dispenses sprays is 4/30.
So first option is correct answer .
Answer:
the number of bacteria increases at a rate of 15% each day
Step-by-step explanation:
Given the function :
f(x) = 256(1.15)^x
The function represents an exponential growth function ; comparing the equation with the general form of an exponential growth function :
f(x) = A(1 + r)^t
A = the initial value of the population, = 256
(1 + r),; r = growth rate
Therefore, to solve for r ;
1 + r = 1.15
r = 1.15 - 1 ; r = 0.15
Hence, growth rate = 0.15 = 0.15 * 100% = 15%
Hence, the number of bacteria increases at a rate of 15% each day
