Which function represents the graph of f(x)=−4|x| after it is translated 3 units down?
Answers
Answer:
The function with blue line (see attachment) represents the graph of [tex]f(x) = -4\cdot |x|[/tex] after it is translated 3 units down.
Step-by-step explanation:
Mathematically speaking, a translation in the y-direction is defined by the following expression:
[tex]g(x) = f(x) + k[/tex] (1)
Where:
[tex]g(x)[/tex] - Resulting function.
[tex]f(x)[/tex] - Original function.
[tex]k[/tex] - Translation factor ([tex]k > 0[/tex] - Translation in the +y direction/[tex]k< 0[/tex] - Translation in the -y direction).
If we know that original function is translated 3 units down and [tex]f(x) = -4\cdot |x|[/tex], then the resulting function is:
[tex]g(x) = -4\cdot |x|-3[/tex]
Lastly, we graph both original and resulting functions with the help of a graphing tool, whose outcome is presented in the image attached below:
Please notice that the red line represents the original function, whereas the blue line represents the resulting function.

USE THIS TO GET "B"
the f(-b/2a) is the highest point,
the vertex of the parabola [-b/2a, f(-b/2a)] will give you the time
and height of the highest point
~~~~~~~~~~~~~~~~~~~
USE THIS TO GET "A"... you will get two answers one will be negative
ignore that one , the positive one is the time to hit the ground
if you factor the equation (use the quadratic formula) you will get
the "zeros" that is where the ball is on the ground...
~~~~~~~~~~~~~~~~~~~~~~~
THIS IS FOR PART "C"
if you set the equation equal to 4.5 meters and factor that for the "zeros" you will get the two times that the ball is at that height.. subtract the two times for the duration

Answer:
f(x) = -4(x +7)(x +1)
Step-by-step explanation:
The x-intercepts tell us that m=-7 and n=-1. We can use the given point to find 'a'.
f(-4) = 36
a(-4+7)(-4+1) = 36
a = 36/-9 = -4 . . . . divide by the coefficient of 'a'

Step-by-step explanation:
The sum of the angles in a triangle is 180°.
∠A +∠B +∠C= 180° (∠ sum of triangle)
50° +∠B +28°= 180°
∠B +78°= 180°
∠B= 180° -78°
∠B= 102°
∠X= 180° -100° (adj. ∠s on a str. line)
∠X= 80°
∠X +∠Z +∠Y= 180° (∠ sum of traingle)
80° +68° +∠Y= 180°
∠Y +148°= 180°
∠Y= 180° -148°
∠Y= 32°
Alternatively,
∠Z +∠Y= ∠W (ext. ∠ of triangle)
68° +∠Y= 100°
∠Y= 100° -68°
∠Y= 32°

B. x + y < 0
Step-by-step explanation:
The two equations can be cleared of fractions by multiplying by 15.
15(2/3(x +1) -4/5y) = 15(1/3)
10(x +1) -12y = 5
10x -12y = -5

15(2/5x +1/3(2y +1)) = 15(1/5)
6x +5(2y +1) = 3
6x +10y = -2

You can find the solutions any way you like, but you can answer the question without doing that. The lines are not parallel, nor coincident, so there is exactly one solution. (choices C and D are incorrect)
If we can locate the solution relative to the line x + y = 0, we can tell if choice A or choice B is correct. A quick look at the intercepts of the equations tells us the solution cannot lie in quadrants 1 or 4. The negative y-intercept and shallow slope (-3/5) of the second equation tells us the solution must lie below the line x + y = 0. That means x+y < 0, choice B.

In the attached graph, the line x+y=0 is dashed orange. Above that line, x+y>0; below that line, x+y<0. We see the intersection point of the red and blue lines is in the region where x+y < 0.
For standard form equation ax+by = c, the x- and y-intercepts are c/a and c/b, respectively, so are easy to find from that form. Knowing these makes it easy to make a sketch of the graph, locating the solution point relative to the line x+y = 0.

When a closed curve is parameterized by {x[t], y[t]}, then as you advance along the curve in the direction of the parameterization, which way do the tangent vectors {x'[t], y'[t]} at {x[t], y[t]} point; in the direction you are going, or in the direction opposite to the direction you are going?
Answers
Answer:
In the direction you are going,
Explanation:
We know that the tangent to {x[t], y[t]} are {x'[t], y'[t]}. Since {x'[t], y'[t]} are tangents at {x[t], y[t]}, we know that the tangent at a point is always parallel to the direction of the function at that point and in the direction of the function. So, the tangent vectors {x'[t], y'[t]} at {x[t], y[t]} point in my direction of motion as I move along the curve.
So, the tangent vectors {x'[t], y'[t]} at {x[t], y[t]} point in the direction you are going.
Which expression is equivalent to (3x^2+4x-7)(x-2)
Answers
Answer:
Option C.
(3x² + 4x– 7)(x) + (3x² + 4x– 7)(–2)
Step-by-step explanation:
From the question given above, we obtained:
3x² + 4x– 7
x – 2
To know which option is correct, we shall obtained the product of the expression. The product of the expression can be obtained as follow:
(3x² + 4x– 7) (x – 2)
NOTE: (3x² + 4x– 7) will be multiplied by x and –2 as illustrated below:
x(3x² + 4x– 7) – 2(3x² + 4x– 7)
Rearrange
(3x² + 4x– 7)(x) + (3x² + 4x– 7)(–2)
Thus, Option C gives the correct answer to the question.

Given the data:
16 25 24 19 33 25 34 46 37
33 42 40 37 34 49 73 46 45
Reordered data :

The mean = ΣX / n
n = sample size ; ΣX = sum of values
The mean = 658 / 18
The mean = 36.56
The Median = 1/2(n+1)th term
1/2(18+1)th term = 1/2(19)th term = 9.5 term
Median = (9th + 10th) / 2 = (34 + 37) / 2 = 35.5
