Answer:b,d,g,h
Step-by-step explanation:
A function assigns the value of each element of one set to the other specific element of another set. The correct option is B, D, G, and H.
What are the domain and range of a function?A function assigns the value of each element of one set to the other specific element of another set.
The domain is the set of values for which the given function is defined.The range is the set of all values which the given function can output.From the given functions the function that has a range of (-∞, ∞) can be found by plotting the graph. Therefore, the parent function that has a range of (-∞, ∞) are:
B. a parent odd-degree power function
D. a parent odd-degree root function
G. a parent logarithmic function with a base greater than 1
H. a parent logarithmic function with a base between 0 and 1
Hence, the correct option is B, D, G, and H.

What percent of 123 is 140? *
Answer:
172.2
Step-by-step explanation:
Answer:
113.8%
Step-by-step explanation:
let the unknown percentage be x%
hence we can re-write the given question as a mathematical equation
"What percent of 123 is 140" can be re-written mathematically as:
x% of 123 = 140
x/100 of 123 = 140
( x/100 )123 = 140 (multiply both sides by 100)
x(123) = 140 x 100
x(123) = 14000 (divide both sides by 123)
x = 14000 / 123
x = 113.8%

Answer:
C. p ∨ q
Step-by-step explanation:
The compound statement is of the form ...
p or q
where ...
p = Memorial day is in July
q = parallel lines intersect
The symbol ∨ is used to represent the disjunction (or).
The symbolic form of the given statement is ...
p ∨ q
__
As it happens, both p and q are false, which means the disjunction is false. That has no bearing on the symbolic representation of it.
_____
∧ represents conjunction (and).
What is the remainder when f(x) = 2x^4 + x^3- 8x - 1 is divided by x - 2?
A. -23
B. 23
C. -3
D. 3
By the remainder theorem, dividing [tex]f(x)[/tex] by [tex]x-2[/tex] leaves a remainder of [tex]f(2)[/tex], which is
[tex]f(2)=2(2)^4+(2)^3-8(2)-1=\boxed{23}[/tex]
which makes B the correct answer.
The remainder when f(x) = 2x^4 + x^3- 8x - 1 is divided by x - 2 is 23
A polynomial is an expression consisting of the operations of addition, subtraction, multiplication of variables.
Polynomial based on degree is linear, quadratic, cubic.
The remainder theorem states that when a polynomial, f(x), is divided by a linear polynomial x - a, the remainder of is to f(a)
Given that f(x) = 2x⁴ + x³ - 8x - 1 is divided by x - 2
x - 2 = 0
x = 2
f(2) = 2(2)⁴ + (2)³ - 8(2) - 1 = 23
Hence The remainder when f(x) = 2x^4 + x^3- 8x - 1 is divided by x - 2 is 23

a-2=3+6a/3
What’s the value of a?
[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Linear Algebra
a-2= 3+6a/3
=> 3(a-2)= 3+6a
=> 3a-6= 3+6a
=> -6-3=6a-3a
=> -9=3a
hence, a=-3
Consider matrix A.
What matrix results from the elementary row operations represented by −2R2+3R1?
Answer:
[tex]A = \left[\begin{array}{ccc}-3&3&2\\-25&-13&0\end{array}\right][/tex]
Step-by-step explanation:
Given the matrix
[tex]A = \left[\begin{array}{ccc}-3&3&2\\8&-1&3\end{array}\right] \\R1 = -3, 5, 2\\R2 = 8, -1, 3\\\\[/tex]
Before we can get the resulting matrix after the elementary operation, we need to get the new second row using the formula −2R2+3R1?
when R1= -3, R2 = 8
−2R2+3R1? = −2(8)+3(-3)
−2(8)+3(-3) = -16-9
−2(8)+3(-3) = -25
R1= 5, R2 = -1
−2R2+3R1? = −2(-1)+3(5)
−2(-1)+3(5) = 2-15
−2(-1)+3(5) = -13
when R1= 2, R2 = 3
−2R2+3R1? = −2(3)+3(2)
−2(3)+3(2) = -6-6
−2(3)+3(2) = 0
Hence the new R2 are -25, -13, 0
The resulting matrix will be:
[tex]A = \left[\begin{array}{ccc}-3&3&2\\-25&-13&0\end{array}\right][/tex]

Annie bakes cookies and cupcakes in a ratio of 2 to 7 for her gift boxes. Her school needs 36 desserts to sell in a bake sale. How many cupcakes will she bake? How many cookies will she bake ?
Let's say cookies are 2x. If there are 2x cookies then there are 7x cupcakes. Now, 2x cookies + 7x cupcakes = 36 desserts.
9x = 36
So, x = 4
Now, remember that cookies = 2x. 2x = 2 times 4 = 8.
She will bake 8 cookies.
