Answer:
10
Step-by-step explanation:
There are 10 groups of 2/5 in 4 which represent the given fraction.
What is the fraction?A fraction is defined as a numerical representation of a part of a whole that represents a rational number.
Equivalent fractions have the same value regardless of their numerators and denominators. When simplified, 6/12 and 4/8 are both equal to 1/2, indicating that they are equivalent in nature.
To find out how many groups of 2/5 are in 4, you will need to divide 4 by 2/5.
To do this, you can follow these steps:
Rewrite the fraction 2/5 as a decimal by dividing the numerator by the denominator. This gives you 0.4.
Divide 4 by 0.4 to find the number of groups of 2/5 that are in 4.
For example, if you divide 4 by 0.4, you get:
4 / 0.4 = 10
Therefore, there are 10 groups of 2/5 in 4.

F(x) 3x^4-4x^2-3
Is this function odd?
Answer:
No.
Step-by-step explanation:
f(x) = 3x^4-4x^2-3
If a function is odd then f(-x) = -f(x) for all values of x.
Here f(-x) = 3(-x)^4 - 4(-x)^2 - 3
= 3x^4 - 4x^2 - 3
So f(-x) = f(x) which makes it even.

how do I find the length of the side of a pentagon?
Answer:
The equation to find the length of one side of a pentagon using the radius looks like this: {display style side length=2rsin ({frac {180} {n}})}. It may look a little complicated, but you can easily plug in the numbers that you already know to simplify the equation and find the length of a side. r represents the radius of the pentagon.

180 feet / day is how many centimeters (cm) /hour?
Answer:
1.27cm/hour
Step-by-step explanation:
there are 24 hours in a day, and 30.48 centimeters in a foot.
180 / 24
7.5
so that is 7.5feet / hour
convert the feet into centimeters
228.6 cm/hour
Unit conversion is a way of converting some common units into another without changing their real value. 180 feet per day in centimeter per hour will be equal to 228.6.
What is Unit conversion?Unit conversion is a way of converting some common units into another without changing their real value.
for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
Given the rate as 180 feet per day. This can be written in cm/hour as,
180 feet per day
= 180 feet / 1 day
Since 1 feet equal to 30.48 centimeters, also, 1 day has 24 hours, therefore,
= (180 × 30.48) centimeters / (1 × 24) hours
= 228.6 centimeters/ hour
= 228.6 centimeters per hour
Hence, 180 feet per day in centimeter per hour will be equal to 228.6.

Question is: Work of the bearing of Q from P.
Answer:
The bearing of Q from P is [tex]75^{o}[/tex].
Step-by-step explanation:
The diagram shows the locations of each point with respect to their bearings. As in bearing, angles are measured with the north axis taken as a reference point.
So that,
the bearing of Q from P would be the value of angle NPQ.
<NPQ = [tex]180^{o}[/tex] - <NQP (alternate angle principle)
= [tex]180^{o}[/tex] - [tex]105^{o}[/tex]
= [tex]75^{o}[/tex]
Thus, the bearing of Q from P is [tex]75^{o}[/tex].
Furthermore, the bearing of P from Q can be determined as;
= [tex]360^{0}[/tex] - [tex]105^{o}[/tex]
= [tex]255^{o}[/tex]
The bearing of P from Q is [tex]255^{o}[/tex].
