Answer:
Option B is correct.
Step-by-step explanation:
Otero translated the phrase "three less than a number" into the expression 3 - x.
I think Otero gave a wrong expression for the phrase.
The true interpretation of the phrase is that if we assume the number as x then three less than a number means x - 3.
Therefore, Otero's expression is inaccurate. Three is being subtracted from a number, so x-3 is what he should have written. (Answer)
Answer:
(a). 2.251 cm
, 2.349 cm, 2.295 cm
(b). 0.023 meters.
Step-by-step explanation:
(a). We are asked to to choose the options that shows the actual measurement of the rainfall.
Since the rounded figure is 2.3 cm, this means that either the tenths digit is 3 with hundredths digit less than 5, or tenths digit is 2 with hundredths digit greater than or equal to 5.
Let us check our given choices one by one.
Therefore, the correct choices are 2.251 cm
, 2.349 cm and 2.295 cm.
(b) We know that 1 cm equals 0.01 meters.
To convert 2.3 cm to meters, we will multiply 2.3 by 0.01.
Therefore, the rounded measurement of rain would be 0.023 meters.
We are going to rewrite the functions correctly:
f (x) = (1/4)
f (x) = (0.4) ^ x
f (x) = 4 ^ x
f (x) = (1/2) ^ x
We observe that we have functions of the form:
f (x) = A (b) ^ x
When
b> 1 The function grows
b <1 Function decreases
Therefore, the function that is growing is:
f (x) = 4 ^ x
Answer:
The function that is increasing is:
f (x) = 4 ^ x
option C)
