Answer:
32.5 miles in 30 minutes.
Step-by-step explanation:
There are a total of 4 - 30 minute segments in a period of two hours. Therefore, in this question, we can simply divide the total distance that Mr Edwards travelled during those two hours by the 4 segments, and that would give us the distance travelled in a single segment of 30-minutes.
130 / 4 = 32.5 miles
Finally, we can see that Mr Edwards travelled 32.5 miles in 30 minutes.

This is a horizontal reflection of y = 2^x
across the y axis.
Step-by-step explanation:
Using the process of elimination, you can spot this answer by applying what is logical about the transformations of an exponential function.
The transformations of a standard exponential function can be given by:
ab^(1/c(x-h))+k
First note that A must be incorrect because -2^x would be a reflection across the x axis which would not match the function g because a reflection across the x axis would cause the exponential growth or decay value b to become a reciprocal and -2 is not a reciprocal of 2.
My problem went from 10a = 50 to 10a / 10 = 50 / 10. What step is this?
Answer:
Step-by-step explanation:
[tex]\frac{10a}{10}[/tex] = [tex]\frac{50}{10}[/tex] ( Division property of equality )
or
10a × [tex]\frac{1}{10}[/tex] = 50 × [tex]\frac{1}{10}[/tex] ( Multiplication property of equality )
(It depends of the options you have in the answer choices)
The general form of an parabola is 4y2+40y+3x+103=0. What is the standard form of the parabola?
9514 1404 393
Answer:
x = -4/3y² -40/3y -103/3
x = -4/3(y +5)² -1
Step-by-step explanation:
Solve for x.
x = (4y² +40y +103)/(-3)
x = -4/3y² -40/3y -103/3 . . . . 'standard form' in the US
__
Taking our clues from the graph*, we can write the vertex form equation as ...
x = -4/3(y +5)² -1 . . . . . . 'standard form' in other places
_____
* The vertex is (-1, -5), so for some leading coefficient, the equation will be ...
x = a(y -(-5))² +(-1) = a(y +5)² -1
The value of 'a' is the scale factor. Here, that is the difference between the parabola value (x = -2 1/3) and the vertex value (x = -1) one unit away from the vertex.

Diego has written a feature story about a drumming circle. What should he include in his visual presentation to interest the audience in the drumming experience? (3 points)
A lecture from one of the drummers
A podcast of a drumming session
A slideshow with a bulleted list about the benefits of drumming
A video of a drumming session
Answer:
A video of a drumming session.
Answer:
D. A video of a drumming session
Explanation:
A presentation can be defined as an act of talking or speaking formally to an audience in order to explain an idea, piece of work, project, and product with the aid of multimedia resources or samples.
Basically, any speaker who wishes to create an effective presentation should endeavor to interact frequently with the audience by holding a conversation and using a multimedia resource.
In this scenario, Diego has written a feature story about a drumming circle. Thus, what he should include in his visual presentation to interest the audience in the drumming experience is a video of a drumming session.
Generally, they say action speaks louder than words, and people often believe what they can see.

Graph -2x + y = 8 please help
Answer
Graph shown below
Step-by-step explanation:
In order to graph something, you need to know the slope and why intercept of the line. One way to do this is to put the equation into slope-intercept form. Slope intercept form is y = mx + b, where m = slope and b = your y-intercept. One way to put the equation -2x = y = 8 into the slope-intercept form is to add the -2x to the other side of the equation. Then you will get y = 8 + 2x. Now, because of the commutative property of addition, you can write the equation as y = 2x + 8. Then graph the equation. Since you know that 8 is a y intercept. You can graph the first point of your line. After, you just use slope (which is 2/1) and graph other points on a graph to get you your line. Hope this helps!

Answer:
[tex]\textbf{D.}\quad g(x)=\sqrt{x+6}+4[/tex]
Step-by-step explanation:
A lot of math is about matching patterns.
For example, ...
g(x) = f(x -h) +k
means g(x) is the function f(x) translated right by h units and up by k units. This will be true for any expression of f(x).
__
In this problem, f(x) = √x. We want to translate it left 6 units (h=-6)*, and up 4 units (k=4).
The notation above means that we will replace x with (x-h) = x+6. and we will add k = 4 to the result.
f(x) = √x
g(x) = f(x+6) +4
g(x) = √(x+6) +4 . . . . . . matches choice D
_____
* Left is the opposite of right, so left 6 units is the opposite of right 6 units. h=6 for right 6 units, so h=-6 for left 6 units. Then x-h = x-(-6) = x+6.
__
Comment on the graph
I find it useful to see a picture with these things. In the attached graphing calculator output, the blue curve is left 6 and up 4 from the red curve. The blue curve is g(x); the red one is f(x).

Find all points (x, y) where the functions f(x), g(x), h(x) have the same value: f(x) = 2^(x−5) + 3, g(x) = 2x − 5, h(x) = 8/x + 10
very fast please
Answer:
The point where all three lines meet is (8, 11)
Step-by-step explanation:
The given functions are;
f(x) = x²⁽ˣ ⁻ ⁵⁾ + 3
g(x) = 2·x - 5
h(x) = 8/x + 10
Equating the simpler functions g(x) to h(x) to find the points of the same value gives;
2·x - 5 = 8/x + 10
2·x - 15 = 8/x
2·x² - 15·x = 8
2·x² - 15·x - 8 = 0
With the aid of an online application, we have;
(2·x + 1)(x - 8) = 0
x = -1/2, or x = 8
The y-values at the point of intersection, is given as follows;
g(x) = 2·x - 5 = 2×(-1/2) - 5 = -6 or g(x) = 2·x - 5 = 2×(8) - 5 = 11
The points where g(x) and h(x) meet are (-1/2, -6) and (8, 11)
To check where the point of intersection of the two functions g(x) ang h(x) meet f(x), we have;
At x = -1/2, f(x) = [tex]2^{(0.5 - 5)} + 3[/tex] = 3.0442
At x = -1/2, f(x) = 2⁽⁸⁻⁵⁾ + 3 = 8 + 3 = 11
Therefore, the point where all three lines meet = (8, 11).
Leading term of -20(x - 2)^15 (4-x)^11
9514 1404 393
Answer:
20x^26
Step-by-step explanation:
The leading term is the one with the highest degree.
In the expansion of (x-2)^15, that will be x^15.
In the expansion of (4-x)^11, that will be (-x)^11 = -x^11.
So, the leading term of the product is ...
(-20)(x^15)(-x^11) = 20x^26
__
In the attached, terms are listed in order of increasing degree, so the "leading" term appears last.
============================================
Work Shown:
The leading term for (x-2)^15 is x^15
The leading term for (4-x)^11 is -x^11
Multiply the outer value -20 with each of those leading terms to get
-20*x^15*(-x^11)
20x^(15+11)
20x^26
which is the leading term of -20(x - 2)^15 (4-x)^11

Two competing sports equipment suppliers sell footballs at different prices. Supplier A charges $85 in shipping, and charges $2.59 per football. Supplier B charges $50 shipped, and charges $4.29 per football. A school wants to buy 40 balls.
What is the equation for supplier A? Answer:
What is the equation for supplier B? Answer:
Which supplier has the lowest average cost per ball? Answer:
The equation for supplier A and supplier B will be y = 2.59x + 85 and y = 4.29x + 50, respectively. Supplier A has the lowest average cost per ball.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Footballs are sold at varying prices by two rival sports equipment vendors. Supplier A costs $85 for shipping and $2.59 for each football. Supplier B costs $50 for shipping and $4.29 per football. A school wants to purchase 40 balls.
Let x be the number of the football and y be the total cost.
The equation for supplier A will be given as,
y = 2.59x + 85
At x = 40, the value of 'y' is given as,
y = 2.59 × 40 + 85
y = $188.6
The equation for supplier B will be given as,
y = 4.29x + 50
At x = 40, the value of 'y' is given as,
y = 4.29 × 40 + 50
y = $221.6
Supplier A has the lowest average cost per ball.
