Step-by-step explanation:
[tex]3(a+b)[/tex]
Since we know that a equals -1/2 and b equals 2 1/2, then we can plug in the values into the equation.
[tex]3(-\frac{1}{2} +2 \frac{1}{2} )[/tex]
First, solve everything in the parentheses.

Consider this polynomial: 7kn+2k^2-2k-2n-5+5n^2
What is coefficient for k?
what is the constant term?
What is the degree of the polynomial?
Answer:
coefficient for k: -2
constant term?: -5
degree of the polynomial: 2
Step-by-step explanation:
The coefficient for k is the number that multiplies k. In this case:
7kn+2k^2-2k-2n-5+5n^2
The constant term is the number that doesn't multiply any variable. In this case:
7kn+2k^2-2k-2n-5+5n^2
The degree of a polynomial is the highest of the degrees of the polynomial's monomials. In this case, the highest monomials are:
7kn+2k^2-2k-2n-5+5n^2
all of them second degree

A) 4.50 g/L
B) 45.0 g/L
C) 4500 g/L
D) 45000 g/L
Answer:

Good luck on your assignment..
The Range of function is, {0, 1, 16, 81}
Option 2 is correct.
The input values to any function is known as domain and output values of function known as range of function.
Given function is, [tex]f(x)=x^{2}[/tex]
Domain is, {0, 1, 4, 9}
Range of function is,
[tex]f(0)=0^{2}=0\\\\f(1)=1^{2}=1\\\\f(4)=4^{2}=16\\\\f(9)=9^{2}=81[/tex]
Thus, Range of function is, {0, 1, 16, 81}

Using sine and cosine, explain how you know where the graph of tangent will
have vertical asymptotes and x-intercepts.
Remember how the tangent function is defined as
[tex]\frac{sinx}{cosx}[/tex]
Now where exactly are the vertical assymptotes? Well, where cosx = 0, because anything over 0 is undefined, and where a value is undefined, you are required to draw a vertical assymptote.
Now where exactly are the x interecepts? Well, where sinx = 0, because remember, an x-intercept is where y = 0, or where it crosses the x-axis, meaning where the tangent function is equal to 0.
So the x-intercepts are at where sinx = 0.
Graph of the tangent will have vertical asymptotes when cosine function is 0 and has x intercept when sine function is 0.
What is Tangent function?Tangent function of an angle in a right angled triangle is defined as the ratio of the opposite side to the adjacent side.
Tangent function can be defined as,
f(x) = tan (x) = [tex]\frac{sin(x)}{cos (x)}[/tex]
Vertical asymptote of a function is the line x = m, where the graph of the function will move to infinity when x approaches m.
Here the function is tan (x).
tan (x) → ∞, when [tex]\frac{sin(x)}{cos (x)}[/tex] → ∞
[tex]\frac{sin(x)}{cos (x)}[/tex] → ∞, when cos (x) = 0, then x = ±[tex]\frac{\pi }{2}[/tex], ±[tex]\frac{3\pi }{2}[/tex], .......
Vertical asymptotes will be line through x = ±[tex]\frac{\pi }{2}[/tex], ±[tex]\frac{3\pi }{2}[/tex], ±[tex]\frac{5\pi }{2}[/tex], .....
x intercept is the point, where the y value equals 0.
That is, tan (x) = 0, at the point of x intercept.
[tex]\frac{sin(x)}{cos (x)}[/tex] = 0
⇒ sin (x) = 0
⇒ x = 0, π, 2π, .....
So tan(x) will have the x intercepts at x = 0, π, 2π, .....
Hence the vertical asymptotes and x intercepts of tan function can be found using sine and cosine.

15,30
18,25
The factor with the sum of 43 is 18+25
25-18=7 so the difference is 7
hope this helps
Step-by-step explanation:
The difference between the numbers be 25 -18 = 7.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
let the two numbers be x and y
The sum of two numbers is 43
x+ y = 43.....(1)
and, product is 450
xy = 450
y= 450 / x
put value of y in equation (1)
x+ 450/x = 43
x² - 43x + 450 = 0
x² - 18x - 15x + 450 = 0
x( x- 18) - 15 ( x- 18)= 0
(x- 15) ( x- 18)= 0
x= 15, 18
So, the number are 18 and 25.
Hence, the difference between the numbers be 25 -18 = 7.
