Answer:</h2>
The correct options are:
- The domain is all real numbers.
- The base must be less than 1 and greater than 0.
- The function has a constant multiplicative rate of change.
<h2>
Step-by-step explanation:</h2>
We know that the exponential function is given by:
where a>0 and b are constants.
Also, it represents a growth function if b>1
and a decay function if 0<b<1
where b is the base.
- x belongs to whole of the real numbers( since the exponential function is well defined for all the real values of x.
Hence, the domain of the function is all the real numbers )
- Also, the graph of a decay function decreases continuously i.e. with the increasing input value the output value decreases.
- The exponential decay function always have a constant multiplicative rate of change i.e. b.
1) In a dozen, there are 12. Since there are 5 dozen, you would multiply 12 by 5, which is 60.
So 5 dozen oranges would cost $60.
2) For this, I'm guessing you need a ratio. So, 2 : 5 for white: blue. When can put that down to 1 white. 1: 2.5. The question (I'm unsure of) is asking ?: 8.5. 8.5÷ 2.5 = 3.4. So you'll multiply the white side as well, 1×3.4=3.4. So 3.4.
3) You need to find what one juice box would cost. So since there were 12 in the pack, you divide the cost by 12.
5.40÷12= .45
Now they are asking for an eighteen pack, so multiply what one would cost by 18.
.45×18= 8.1
It would cost $8.10.
15) It is given that the charge of the waffle cone = $1.85
Charge per scoop of an ice cream = $0.60
Let C be the total cost.
So, total charge of one wafflce cone ice cream = charge of the waffle cone + (0.6 times number of scoops
C = 1.85 + 0.6x
16) To find the cost for 6 scoops of ice cream, put x = 6 in the above expression and simplify.
C = 1.85 + 0.6(6)
= 1.85 + 3.6
= 5.45
Hence, cost of 6 scoops of ice cream = $5.45.
Answer:
70 = 5%
Step-by-step explanation:
6% x 1385
1/20 = 1/1 x 70/1 = 70 = 5%
Step-by-step explanation:
W = 1/ - 4b
I think that's the answer
