Answer:
f = 1.1 Hz
Step-by-step explanation:
Given that,
The velocity of an ocean wave, v = 4.4 m/s
The distance between the crest of each wave is 4 m.
We need to find the frequency of the waves.
The distance between the crest of a wave is called the wavelength of a wave.
The relation between the frequency, wavelength and the velocity of a wave is given by :
[tex]v=f\lambda\\\\f=\dfrac{v}{\lambda}\\\\f=\dfrac{4.4}{4}\\\\f=1.1\ Hz[/tex]
So, the frequency of the waves is 1.1 Hz.

A shoe sales associate earned $300 in November. In December she earned 8% more than she did in November. How much she earn in December? *
Answer:
$324.00
Step-by-step explanation:
Increase the number by 8% of its value.
Percentage increase = 8% × 300
New value =
300 + Percentage increase =
300 + (8% × 300) =
300 + 8% × 300 =
(1 + 8%) × 300 =
(100% + 8%) × 300 =
108% × 300 =
108 ÷ 100 × 300 =
108 × 300 ÷ 100 =
32,400 ÷ 100 =
324
$24.. 8% of $300 equals 24 so the associate made $324 dollars in December. 24+300=324

Step-by-step explanation:
Multiply the dividend fraction numerator with the divisor fraction denominator to get the numerator
Multiply the dividend fraction denominator with the divisor fraction numerator to get the denominator = 36/12
Reduce the fraction by finding the greatest common factor. The greatest common factor of 36 and 12 is 12
Divide the numerator and denominator by the greatest common factor (12)
= 3/1
Convert to a mixed fraction by finding the whole number and remainder
= 3
Answer:
3
Step-by-step explanation:
Factor the numerator and denominator and cancel the common factors.
It will give you 3.

Work out 23% of 42.
Give your answer correct to 1 decimal place.
The value of 23 % of 42 is 9.7
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number be A = 42
Now , let the percentage of the number A = 23 %
And , the equation will be
The 23 % of the number be = y
So , y = 23 % of 42
And , the equation is
y = ( 23 / 100 ) x 42
y = 0.23 x 42
On simplifying the equation , we get
y = 9.66
y ≈ 9.7
Therefore, the value of y is 9.7
Hence , The value of 23 % of 42 is 9.7

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 19, 38,76,... 19,38,76,... \text{Find the 8th term.} Find the 8th term.
Answer:
To find the next number in the sequence, multiply the number before by 2.
By this logic, numbers 4-8 in the sequence would be 152, 304, 608, 1,216, and 2,432
Thus, the 8th term is 2,432

B. Over the interval [0, 1], b(x) is positive and is decreasing.
c. Over the interval [0, 1], 5(x) is positive and is increasing.
D. Over the interval [0, 1], b(x) is negative and is decreasing.
The only statement that is true regarding the given graph of polynomial b(x) is; Option D; Over the interval [0, 1], b(x) is negative and is decreasing.
The given graph represents the polynomial b(x). Let us look at the options;
Option A; Over the interval (0, 1), we can see that the curve is decreasing from b(x) = 0 to b(x) = -2. Thus, the statement is wrong.
Option B; Over the interval of (0, 1), b(x) is not positive over the interval (0, 1) and so the statement is wrong.
Option C; Over the interval of (0, 1), b(x) is not positive and increasing and so the statement is wrong.
Option D; Over the interval of (0, 1), b(x) is negative and is also decreasing and so this option is correct.

If r=3q + 2 and q = 1/3n for n = 1,2 or 3,
what is the least possiable value of r ?
A. 1
B. 2 1/9
C. 2 1/3
D. 3
Answer:
D. 3
Step-by-step explanation:
For n = 1:
q = 1/3 * 1 = 1/3
r = 3 * 1/3 + 2 = 1 + 2 = 3
For n = 2:
q = 1/3 * 2 = 2/3
r = 3 * 2/3 + 2 = 2 + 2 = 4
For n = 3:
q = 1/3 * 3 = 1
r = 3 * 1 + 2 = 3 + 2 = 5
Therefore, from the values of r that we found (3, 4, 5), the minimal value is 3.

Which graph shows a proportional relationship?
There is a linear relationship between the variables x and y. And the line that passes through the origin. Then the correct option is C.
What are ratios and proportions?A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A proportional is a mathematical expression in which two things are equal.
Let the two variables x and y.
Where x is an independent variable and y is the dependent variable that depends on x directly. Then we have
The variable y is directly proportional to the variable x.
y ∝ x
When the proportionality sign is removed a constant k comes into the equation. That is given as
y = kx
There is a linear relationship between the variables x and y.
And the line that passes through the origin.
The graph is shown below.
