The solution to the given functions are:
a) f(x) is an even function because f(−x) = f(x)
b) f(x) is an odd function because f(-x) = -f(x)
c) f(x) is neither even nor odd because f(-x) ≠ f(x) nor f(-x) ≠ -f(x)
How to find the even or odd function?A function f is said to be an even function if f(−x) = f(x), for all x in the domain of f. A function f is said to be an odd function if f(−x) = −f(x), for all x in the domain of f.
a) The function is given as:
f(x) = 2x⁴ - x² - 4
f(-x) = 2(-x)⁴ - (-x)² - 4
= 2x⁴ - x² - 4
Thus, it is an even function because f(−x) = f(x)
b) The function is given as:
f(x) = 2x³ + ¹/₋ₓ
f(-x) = 2(-x)³ + ¹/₍₋ₓ₎
= -2x - ¹/ₓ
Thus, it is an odd function because f(-x) = -f(x)
c) The function is given as:
f(x) = 2x² - 7x + 10
f(-x) = 2(-x)² - 7(-x) + 10
f(-x) = 2x² + 7x + 10
Thus, it is neither even nor odd because f(-x) ≠ f(x) nor f(-x) ≠ -f(x)

Step-by-step explanation:
If your weekly salary is $1780 and taxes takes out $440, then 24.7% you pay in taxes.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that the weekly salary is One thousand seven hundred and eighty $1780.
Taxes takes out is four hundred and forty $440.
We need to find the percent of tax we have paid.
This can be found by as below.
1780x=440
Divide both sides by 1780
x=440/1780
x=0.247
Now multiply with 100 as it is a hundredth part
0.247×100=24.7%
Hence, 24.7% is the percentage of tax we have paid.

The magnitude of angle Z include the following:
cosZ = 0.471
sinZ = 0.88
tanZ = 1.875
How to calculate the magnitude of angle Z?In order to determine the magnitude of angle Z, we would apply the basic trigonometric ratio because the given side lengths represent the adjacent side, opposite side, and hypotenuse of a right-angled triangle.
cos(θ) = Adj/Hyp
Where:
Adj represents the adjacent side of a right-angled triangle.Hyp represents the hypotenuse of a right-angled triangle.θ represents the angle.For cosZ, we would apply the cosine trigonometric ratio as follows;
cosZ = 13.6/28.9
cosZ = 0.4706
Z = cos⁻¹(0.4706)
Z = 61.93°.
For sinZ, we would apply the sine trigonometric ratio as follows;
sinZ = 25.5/28.9
sinZ = 0.8824
Z = sin⁻¹(0.8824)
Z = 118.07.
For tanZ, we would apply the sine trigonometric ratio as follows;
tanZ = 25.5/13.6
tanZ = 1.875
Z = tan⁻¹(1.875)
Z = 61.93.

The dot isn’t shaded so > or <
From -55, it’s showing small than
From -49, it’s showing greater than
x < -55 or x > -49
Answer: x < -55 or x > -49
Step-by-step explanation:
x < -55 or x > -49
They both start with an opened circle, and also these two opened circle dots do not connect to each other. On the left side, the number is going from -55 to the smaller side, -57 or less, so we can say that x is smaller than -55. On the right side, the number goes from -49 to the bigger number, we can say that x is greater than -49.

meteroloogist track severe stoms using Doppler radar. A polar grid is used to measure distances as the storms progress. If the center of the radar screen is the origin and each ring is 10 miles farther from the center, what is the equation of the fourth ring
Answers
Answer:
[tex]$(x-h)^2+(y-k)^2= (r+ 40 )^2$[/tex]
Step-by-step explanation:
It is given that a meteorologist is using a Doppler radar to find out the distance of the storm as it passes using a polar grid.
The origin of the radar screen is its center.
And the distance between each ring is 10 miles from the center.
So let :
r = radius
h and k = be the coordinates of the center.
So the equation of a circle is :
[tex]$(x-h)^2+(y-k)^2= r^2 $[/tex]
Now the equation of the fourth circle when the radius changes by 10 miles is :
[tex]$(x-h)^2+(y-k)^2= (r+ 40 )^2$[/tex]
