Answer:
Option C
Step-by-step explanation:
WE are given a graph of exponential function and asked to find out of four functions which function the graph represents.
We find that any function of the form
passes through (0,1) for all a
Hence we cannot distinguish any thing from the point
Let us consider when x=1
Then first function will have point as (1,2.4)
II funciton (1,0.31)
III function (1,0.45)
IV funciton (1,1.8)
From the graph given we find that the point of y is less than 1. Hence it can be either II or III
Consider x=-1
Then II function has point as (-1,3.225) and III function has point as (-1,2.222)
From the graph we find that the graph satsified only the point (-1,2.2222)
Hence OPtion III is right
Answer:
x = 4
Step-by-step explanation:
Set the exponents equal to each other
2x + 1 = x + 5
Subtract x from both sides
x + 1 = 5
Subtract one from both sides
x = 4
So, the value of x is equal to 4.
Answer:
-26oF
Step-by-step explanation:
The difference between the low temperature and the wind-chill temperature is the result obtained when the low temperature is subtracted from the wind-chill temperature.
This difference
= -7oF - 19oF
= -26oF
The negative sign shows that there was a fall in temperature.
You either need to add the two times together or you need to subtract them
Answer:
A. 27 π cubic inches
Step-by-step explanation:
The volume of a cylinder is calculated using the formula;
From the given information, the smallest candle has a radius of 0.5 inches and a height of 3 inches.
We substitute 
and 
into the given formula.
The vlume of the smallest candle is
from the given information, the other two candles are scaled versions of the smallest, with scale factors of 2 and 3.
The volume of the other two candles will be 
and 
The wax needed to create one set of candle is
The correct answer is A
