Answer:
(a) These are the same function
Step-by-step explanation:
Given
[tex]x + x^2[/tex] and [tex]u + u^2[/tex]
Required
Are they the same?
Yes, they are the same function and this is proved below.
[tex]x + x^2[/tex]
Represent as a function:
[tex]f(x) = x + x^2[/tex]
[tex]u + u^2[/tex]
Represent as a function
[tex]f(u) = u + u^2[/tex]
Let x = u
Substitute u for x in [tex]f(x) = x + x^2[/tex]
[tex]f(u) = u + u^2[/tex]
This implies that:
[tex]f(x) = f(u)[/tex]
[tex]x + x^2 =u + u^2[/tex]
PS: The information that x and u are real numbers are for all real numbers; So, we can not assume that x and u are different numbers
Hence:
(b) and (c) are wrong
please help me and i love you forever ;)
Answer:
x = 45°
y = 90°
Step-by-step explanation:
Angles in a Triangle
The sum of the internal angles in a triangle is 180°.
On the other hand, the tick marks on the triangle tell us it's an isosceles triangle, thus the angle formed at both sides of the triangle is x.
Finally, angle x and 135° are a linear pair that always add up to 180°, thus
x = 180 - 135 = 45
x = 45°
The angle y can be found by completing the measure needed to 180°:
x + x + y = 180
y = 180 - 2x = 180 - 90
y = 90°
A birthday party has a grab bag for each of the guests. There are 8 bags filled with candy, 5 containing CDs, and 2 grand prize bags with gift certificates. The bags are identically wrapped and shuffled. Joe is first to choose a bag, and Devon is second. What is the probability that Joe and Devon will both choose grand prize bags?
Answer:
1/105
Step-by-step explanation:
First, the probability that Joe chooses a grand prize bag is 2/15 because there are 2 grand prize bags out of 15 total bags.
Next, the probability that Devon chooses a grand prize bag is 1/14 because if Joe already chose one of the grand prize bags, there is only 1 left out of a total of 14 bags left.
The last step is to multiply those two bags, so [tex]\frac{2}{15} * \frac{1}{14}[/tex] = [tex]\frac{1}{105}[/tex]
PLEASE HELP I ONLY HAVE 10 MORE QUESTIONSS
Answer:
Length
√45 units
Distance
√13 units
Step-by-step explanation:
Here, we want to calculate the length and the distance between the points
To calculate the length, we need the coordinates of the points
These are;
(1,-2) and (4,4)
the length can be calculated using the formula for the distance between two points
Mathematically, that will be;
D = √(x2-x1)^2 + (y2-y1)^2
D = √(1-4)^2 + (-4-2)^2
D = √(9 + 36)
D = √45 units
We use the same formula to get the distance between the two given points
that will be;
D = √(5-3)^2 + (-2-1)^2
D = √(2)^2 + (3)^2
D = √13 units

An English book consists of two sections, literature and grammar, in a ratio of 3:2. How much of each type of content will be needed to make a book of 150 pages?
Answer:
For Literature = 90 pages
For Grammar = 60 pages
Step-by-step explanation:
An English book consists of two sections, literature and grammar, in a ratio of 3:2. How much of each type of content will be needed to make a book of 150 pages?
Literature : Grammar
3 : 2
Total number of Proportion = 3 + 2 = 5
For Literature
= 3/5 × 150 pages
= 90 pages
For Grammar
= 2/5 × 150 pages
= 60 pages

What is the Domain of the graph?, and What is the Range of the graph ?
Answer:
Domain is 0-12 and the range is 0-10
Step-by-step explanation:
The domain is the x values and the range is the y values
Answers:
Domain: [tex]0 \le x \le 12[/tex]
Range: [tex]0 \le y \le 10[/tex]
===============================================
Explanation:
The domain is the set of all possible x inputs. The x axis is along the horizontal, so x refers to the number of minutes. The smallest x can get is x = 0 and the largest is x = 12. To describe everything in between those endpoints, including both endpoints, we write [tex]0 \le x \le 12[/tex]
The range is the set of all possible y outputs. The y axis is vertical so y refers to the distance from home. The smallest distance is y = 0 and the largest distance is y = 10. So we say the range is [tex]0 \le y \le 10[/tex] to describe everything in between 0 and 10, including those endpoints.
Side note: 12 minutes = 12/60 = 0.2 hours. You travel 10 miles in 0.2 hours, so the speed is distance/time = 10/0.2 = 50 mph.

Use the equation to help list the zeros of the function.
❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
[tex]f(x) = - 5 {x}^{2} + 10x + 8[/tex]
[tex]0 = - 5 {x}^{2} + 10x + 8[/tex]
[tex] - 5 {x}^{2} + 10x + 8 = 0[/tex]
[tex]delta = {10}^{2} - 4( - 5)(8)[/tex]
[tex]delta = 100 + 160[/tex]
[tex]delta = 260[/tex]
[tex]x = \frac{ - (10) + \sqrt{delta} }{2 \times ( - 5)} \\ [/tex]
[tex]x = \frac{ - 10 + \sqrt{260} }{ - 10} \\ [/tex]
[tex]x = \frac{ - 10 + 2 \sqrt{65} }{ - 10} \\ [/tex]
[tex]x = \frac{ - 5 + \sqrt{65} }{ - 5} \\ [/tex]
And
[tex]x = \frac{ - 10 - \sqrt{delta} }{ - 10} \\ [/tex]
[tex]x = \frac{ - 10 - 2 \sqrt{65} }{ - 10} \\ [/tex]
[tex]x = \frac{ 5 + \sqrt{65} }{5} \\ [/tex]

Thus list the zeroes of the function is :

y =
y = -3x
y = 3x
y = x
Answer:
[tex]y = -3x[/tex]
Step-by-step explanation:
Given
The attached graph
Required
Determine the graph equation
To do this, we pick any 3 corresponding points of x and y
[tex](x_1,y_1) = (0,0)[/tex]
[tex](x_2,y_2) = (2,-6)[/tex]
[tex](x_3,y_3) = (-4,12)[/tex]
The equation can then be solved using linear interpolation as follows:
[tex]\frac{y-y_3}{x-x_3} = \frac{y_2 - y_1}{x_2-x_1}[/tex]
This gives:
[tex]\frac{y-12}{x-(-4)} = \frac{-6 -0}{2-0}[/tex]
[tex]\frac{y-12}{x+4} = \frac{-6 -0}{2-0}[/tex]
[tex]\frac{y-12}{x+4} = \frac{-6}{2}[/tex]
[tex]\frac{y-12}{x+4} = -3[/tex]
Multiply both sides by x + 4
[tex](x + 4) * \frac{y-12}{x+4} = -3 * (x + 4)[/tex]
[tex]y - 12 = -3 *(x + 4)[/tex]
Open bracket
[tex]y - 12 = -3x -12[/tex]
Add 12 to both sides
[tex]y - 12+12 = -3x -12+12[/tex]
[tex]y = -3x[/tex]
