Which is greater, 0.04 or 0.4? Explain
2 answers:
To compare decimals such as 0.04 and 0.4, first, line up the decimal points of the two numbers.
Next, we compare the digits place by place starting on the left.
Notice that 0 and 0 are the same but moving to the right one column, notice that 0 is less than 4 so 0.04 is less than 0.4 or stated another way, 0.4 is greater than the decimal 0.04.
A common mistake is to see the 4 is 0.04 and 0.4 and assume that these decimals are equivalent but don't fall into this trap.

Answer:
The improve in speed is 3.9334 words/min
Step-by-step explanation:
we will find speed at both occasions and then we can subtract them
First test:
total number of word =694
total time =15 min
we know that
speed = (total number of words)/( total time)
now, we can plug values
speed is
word/min
word/min
Second test:
total number of word =753
total time =15 min
we know that
speed = (total number of words)/( total time)
now, we can plug values
speed is
word/min
word/min
So, improve in speed is
word/min
A function assigns the values. The function of the given graph is y=3(4)ˣ, thus, the correct option is C.
<h3>What is a Function?</h3>A function assigns the value of each element of one set to the other specific element of another set.
The complete question is:
If the parent function is y = 4ˣ, which is the function of the graph?
y = −2(4)ˣ
y = −3(4)ˣ
y = 3(4)ˣ
y = 2(4)ˣ
Since the graph intersect the y-axis at 3, and the parent function of the function is y=4ˣ, therefore, we can write,
y = A(4)ˣ
3 = A(4)⁰
3 = A × 1
A = 3
Hence, the function of the given graph is y=3(4)ˣ, thus, the correct option is C.
