Answer:
The function g(x) has a higher y-intercept.
Step-by-step explanation:
First function f(x):
Slope = (-1, - (-1) / -4 - -1) = 0
So its equation is y = -1.
The y-intercept is (0, -1).
Second function g(x):
Slope = (13-9)/ (6-4) = 2.
y - y1 = m(x - x1) where m = slope and (x1, y1) is a point on the line, so we have:
y - 9 = 2(x - 4)
y = 2x - 8 + 9
y = 2x + 1.
So the y-intercept is (0, 1).
Does the following represent a function?
f = [ (3, -1), (2, 5), (4, -6), (3, 4), (5, -8) ]
Answer:
No, because 3 (domain) has two different ranges: -1 and 4.
Also, apply the vertical line rule.

Let f(x)=x2+8x. Evaluate f(x)=--16
Answer:
-384
Step-by-step explanation:
f(x) =x^2+8x
evaluate f(x)=-16
input -16 for x
-16^2+8(-16)
-16^2= -256
then, 8*-16=-128
add the two negatives
-256+-128= -384

Maria's calculator showed the expression 23,000 + 4.5E3.What is another way to write the expression Maria's calculator showed?
Large numbers can be easily written to a required significant figures using the standard notation. So that, the expression on Maria's calculator also can be written in standard form as 2.75 x [tex]10^{4}[/tex]
An exponential function can be used when dealing with large numbers, which can also be written in a standard form. This helps to simplify and express large numbers scientifically.
The value on Maria's calculator = 23,000 + 4.5E3
But,
4.5E3 = 4.5 x 1000
= 4500
So that,
23,000 + 4.5E3 = 23,000 + 4500
= 27500
= 2.75 x [tex]10^{4}[/tex]
Thus,
23,000 + 4.5E3 = 2.75 x [tex]10^{4}[/tex]
Therefore, the expression on Maria's calculator also can be written in standard form as 2.75 x [tex]10^{4}[/tex]

9514 1404 393
Answer:
12 1/2 laps
Step-by-step explanation:
To find the number of laps, divide the distance by the distance per lap.
(3 1/8) ÷ (1/4) = (3 1/8) × (4/1) = 3·4 +(1/8)·4 = 12 4/8 = 12 1/2
Quadir needs to jog 12 1/2 laps if he wants to jog 3 1/8 miles.

mei is knitting a scarf with diagonal stripes before she began she laid out the pattern on a coordinate grid where each unit represented 2 inches. On the grid the first stripe began at (2,0) and ended at (5,4). All the stripes are the same length. How many inches long is each stripe on the scarf?
The distance between two points on the coordinate geometry is [tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]. The first stripe is 10 inches long.
Given that:
[tex](x_1,y_1) = (2,0)[/tex]
[tex](x_2,y_2) = (5,4)[/tex]
First, we calculate the number of units using distance formula:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
So, we have:
[tex]d = \sqrt{(2 - 5)^2 + (0 - 4)^2}[/tex]
[tex]d = \sqrt{(-3)^2 + (-4)^2}[/tex]
[tex]d = \sqrt{25}[/tex]
Take positive square root
[tex]d = 5[/tex]
From the question, we understand that each unit is 2 inches.
So, the length of the stripe is:
[tex]Length = 2 \times d[/tex]
[tex]Length = 2 \times 5[/tex]
[tex]Length = 10[/tex]
Hence, the first stripe is 10 inches long.

Can somebody tell me the domain and show me or tell me the work plz.
Answer:
Set the denom to 0 and solve.
x^2 - 16 = 0 --> x = -4,4
This means the vertical asymptote is 4, -4.
Therefor, the domain is for all real numbers that are not 4, -4.
We ignore the top because if the numerator was 0, it's still a number. But if the denom was 0, then it would be impossible (you can't divide by 0). So for all numbers that can go into the denom that aren't 0, is your domain.
dados os vetores u = (2, -3, -1) e v = (1, -1, 4) o resultado de (u + v) x ( u - v) é igual a?
The cross product distributes over sums, so we have
[O produto cruzado distribui somas, então temos]
(u + v) × (u - v) = (u × u) + (v × u) + (u × (-v)) + (v × (-v))
(u + v) × (u - v) = (u × u) + (v × u) - (u × v) - (v × v)
The cross product of a vector with itself is the zero vector, so
[O produto vetorial de um vetor com ele mesmo é o vetor zero, então]
(u + v) × (u - v) = 0 + (v × u) - (u × v) - 0
(u + v) × (u - v) = (v × u) - (u × v)
The cross product is anticommutative, meaning that for two vectors u and v,
[O produto vetorial é anticomutativo, o que significa que para dois vetores u e v,]
u × v = - (v × u)
So we end up with
[Então acabamos com]
(u + v) × (u - v) = (v × u) + (v × u)
(u + v) × (u - v) = 2 (v × u)
Given that u = (2, -3, -1) and v = (1, -1, 4), compute the cross product as follows:
[Dados esses vetores, calcule o produto vetorial:]
(1, -1, 4) × (2, -3, -1)
= ((1, 0, 0) - (0, 1, 0) + 4 (0, 0, 1)) × (2 (1, 0, 0) - 3 (0, 1, 0) - (0, 0, 1))
= 2 (1, 0, 0) × (1, 0, 0) - 2 (0, 1, 0) × (1, 0, 0) + 8 (0, 0, 1) × (1, 0, 0)
… … - 3 (1, 0, 0) × (0, 1, 0) + 3 (0, 1, 0) × (0, 1, 0) - 12 (0, 0, 1) × (0, 1, 0)
… … - (1, 0, 0) × (0, 0, 1) + (0, 1, 0) × (0, 0, 1) - 4 (0, 0, 1) × (0, 0, 1)
Recall the definition of the cross product:
[Lembre-se da definição de produto vetorial:]
(1, 0, 0) × (0, 1, 0) = (0, 0, 1)
(0, 1, 0) × (0, 0, 1) = (1, 0, 0)
(0, 0, 1) × (1, 0, 0) = (0, 1, 0)
The product reduces to
[O produto se reduz a]
(1, -1, 4) × (2, -3, -1)
= -2 (0, 1, 0) × (1, 0, 0) + 8 (0, 0, 1) × (1, 0, 0)
… … - 3 (1, 0, 0) × (0, 1, 0) - 12 (0, 0, 1) × (0, 1, 0)
… … - (1, 0, 0) × (0, 0, 1) + (0, 1, 0) × (0, 0, 1)
= 2 (0, 0, 1) + 8 (0, 1, 0) - 3 (0, 0, 1) + 12 (1, 0, 0) + (0, 1, 0) + (1, 0, 0)
= - (0, 0, 1) + 9 (0, 1, 0) + 13 (1, 0, 0)
= (13, 9, -1)
Finally,
[Finalmente,]
(u + v) × (u - v) = 2 (13, 9, -1) = (26, 18, -2)

Answer:
The graph of a function and its inverse are reflections of each other in the line y=xFor each ordered pair (x, y) in a function, the corresponding ordered pair in the inverse function is (y, x)see the attachment for the tables of valuesStep-by-step explanation:
Consider the function and its inverse shown in the second attachment. The function is ...
f = {(a, 3), (b, 1), (c, 2)}
The inverse function is ...
f^-1 = {(3, a), (1, b), (2, c)}
You will notice that the "x" and "y" of each pair are swapped between the function and its inverse. That is the point of an inverse function. It gives you the input that caused the function to create the output. For example, the pair (3, a) in the above inverse function tells you that the output 3 was the result of an input of 'a' to the original function.
__
On a graph, the swapping of input and output is essentially equivalent to relabeling the axes. If we keep the same x- and y-axis labels, it is equivalent to reflecting the function graph across the line y=x. That reflection is represented by the transformation (x, y) ⇒ (y, x).
__
The point of the exercise here is for you to identify some ordered pairs of one of the functions and realize that the inverse function reverses their order. You are to see that the graph of the function and its inverse are reflections of each other across the diagonal line y=x.
