The ordered pair that has a rise of -2 and a run of 3, and also lies on the same line as the point (6, 2) is: d) (9,0) and (12, -2)
The Rise and Run of a LineThe rise of a line is the change in the y-values.The run of a line is the change in the x-values.The rise of the ordered pair, (9,0) and (12, -2):
Rise = change in y = -2 - 0 = -2.
The run of the ordered pair, (9,0) and (12, -2):
Run = change in x = 12 - 9 = 3.
Therefore, the ordered pair that has a rise of -2 and a run of 3, and also lies on the same line as the point (6, 2) is: d) (9,0) and (12, -2)

You could technically have any value you want, but for me 1/6 is easiest because 1/2 and 1/3 will scale up to this like so
1/2 = (1/2)*(3/3) = 3/6
1/3 = (1/3)*(2/2) = 2/6

Solve for the missing side
Answer:

Step-by-step explanation:
The position of a ball after it is kicked can be determined by using the function f left parenthesis x right parenthesis equals negative 0.11 x squared plus 2.2 x plus 1f(x)=−0.11x2+2.2x+1, where f(x) is the height, in feet, above the ground and x is the horizontal distance, in feet, of the ball from the point at which it was kicked. What is the height of the ball when it is kicked? What is the highest point of the ball in the air?
Answer:
When kicked, the height of the ball is 1 feet. The highest point for the ball's trajectory is 12 feet.
Step-by-step explanation:
We are given that the height is given by [tex]f(x)=-0.11x^2+2.2x+1[/tex]. The distance between the ball to the point where it was kicked is 0 right at the moment the ball was kicked. So, the height of the ball, when it was kicked is f(0) = -0.11*0 + 2.2*0 +1 = 1.
To determine the highest point, we will proceed as follows. Given a parabola of the form x^2+bx + c, we can complete the square by adding and substracting the factor b^2/4. So, we get that
[tex] x^2+bx+c = x^2+bx+\frac{b^2}{4} - \frac{b^2}{4} +c = (x+\frac{b}{2})^2+c-\frac{b^2}{4}[/tex].
In this scenario, the highest/lowest points is [tex]c-\frac{b^2}{4}[/tex} (It depends on the coefficient that multiplies x^2. If it is positive, then it is the lowest point, and it is the highest otherwise).
Then, we can proceed as follows.
[tex] f(x) = -0.11x^2+2.2x+1 = -0.11(x^2-20x)+1[/tex]
We will complete the square for [tex]x^2-20x[/tex]. In this case b=-20, so
[tex] f(x) = -0.11(x^2-20x+\frac{400}{4}-\frac{400}{4})+1 = -0.11(x^2-20x+100-100)+1[/tex]
We can distribute -0.11 to the number -100, so we can take it out of the parenthesis, then
[tex] f(x) = -0.11(x^2-20x+100)+1+100*0.11 = -0.11(x^2-20x+100)+1+11 = -0.11(x-10)^2+12[/tex]
So, the highest point in the ball's trajectory is 12 feet.
Answer:
Initial height = 1ft
Heighest height = 12ft
Step-by-step explanation:
In order to solve this problem, we can start by graphing the given height function. This will help us visualize the problem better and even directly finding the answers, since if you graph it correctly, you can directly find the desired values on the graph. (See attached picture)
So, the initical height happens when the x-value is equal to zero (starting point) so all we need to do there is substitute every x for zero so we get:
[tex]f(x)=-0.11x^{2}+2.2x+1[/tex]
[tex]f(0)=-0.11(0)^{2}+2.2(0)+1[/tex]
which yields:
[tex]f(0)=1 [/tex]
so the height of the ball when it is kicked is 1 ft.
In order to find the highest point of the ball in the air, we must determine the x-value where this will happen and that can be found by calculating the vertex of the parabola. (see the graph)
the vertex is found by using the following formula:
[tex]x=-\frac{b}{2a}[/tex]
in order to find "a" and "b" we must compare the given function with the standard form of a quadratic function:
[tex]f(x)=ax^{2}+bx+c[/tex]
[tex]f(x)=-0.11x^{2}+2.2x+1[/tex]
so:
a=-0.11
b=2.2
c=1
so the vertex formula will be:
[tex]x=-\frac{b}{2a}[/tex]
[tex]x=-\frac{2.2}{2(-0.11)}[/tex]
so we get that the highest point will happen when x=10ft
so the highest point will be:
[tex]f(10)=-0.11(10)^{2}+2.2(10)+1[/tex]
f(10)=12ft
so the highes point of the ball in the air will be (10,12) which means that the highest the ball will get is 12 ft.
Find the lowest common denominator for the fractions shown.
8/51
19/85
a. 255
b. 17
c. 4,335
Answer:
A.
Step-by-step explanation:
Just find the lowest common multiple of 51 and 85.
51 = 3 * 17
85 = 5 * 17
3 * 5 * 17 = 255
The lowest common denominator for the fractions is 17.
What are Fractions?The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.
The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.Given:
fraction = 8/51 and 19/ 85
Now, LCM of 51 and 85.
51 = 17 x 3
85= 17 x 5
So, the least common multiple is 17.
Hence, the lowest common denominator for the fractions is 17.

Please help!!! A plane takes off from the airport and climbs at a steady rate. If the plane travelled
5.4km after take-off and gained 1120m of elevation (vertical gain), what angle did the plane take off at?
Answer:
[tex] 12.0^\circ [/tex]
Step-by-step explanation:
Think of a right triangle. It may help you to draw it.
Start at a point. Draw a point and label it point A. That is where the plane takes off from. Now draw a diagonal segment tilted up to the right and stop at a point and label it B. Segment AB is the path of the airplane. Now draw a segment down vertically to a point you will label C, so that points A and C are on the same horizontal line. Connect points A and C.
You now have a right triangle. Angle C is the right angle. AB is the hypotenuse and is 5.4 km. That is the actual distance the plane traveled. BC is 1.12 km (since 1120 m = 1.12 km) and is a leg of the right triangle. The angle you are looking for is angle A.
For angle A, BC is the opposite leg. AB is the hypotenuse.
The trig ratio that relates the opposite leg to the hypotenuse is the sine.
[tex] \sin A = \dfrac{opp}{hyp} [/tex]
[tex] \sin A = \dfrac{1.12~km}{5.4~km} [/tex]
[tex] \sin A = 0.2074 [/tex]
[tex] A = \sin^{-1} 0.2074 [/tex]
[tex] A = 12.0^\circ [/tex]

A store buys shirts from a distributor for $10 each and marks them up 50%. After selling them for 3 weeks, they put them on sale for 50% off. Is the discounted price $10?
Answer:
No, it’s 7.50
Step-by-step explanation:
The discounted price is 7.5, but according to question the discounted price is $10. Therefore given statement is wrong.
What is percentage?Percentage is a measurement to find value of given number out of hundred.
Given that,
Cost price of one shirt = $10.
Also, Shopkeeper marks up 50 % on shirts.
Marked up price = 10 x 50% = 10 x 50 / 100 = $15
Since, shopkeeper gives discount as put the shirts on sale for 50% off.
So the price after giving discount = 15 x 50 / 100 = 7.5
The discounted price of shirt is 7.5.
Hence, the given statement that is discount price is $10 is incorrect.

Angle c is inscribed in circle O. AB is a diameter of circle O. what is the radius of circle.
Answer:
The value of radius is 7.5 units
Step-by-step explanation:
Given that a line that pass through the origin and form a triangle is a right-angle triangle. So in order to find the diameter/hypotenuse, you have to use Pythogaras Theorem :
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
Let a = 12 units,
Let b = 9 units,
Let c = hypo.,
[tex] {hypo.}^{2} = {12}^{2} + {9}^{2} [/tex]
[tex] {hypo.}^{2} = 225[/tex]
[tex]hypo. = \sqrt{225} [/tex]
[tex]hypo. = 15 \: \: units[/tex]
We have found out that the hypotenuse of the triangle is the diameter of circle. So in order to find radius, you have to divide it by 2 :
[tex]radius = diameter \div 2[/tex]
[tex]radius = 15 \div 2[/tex]
[tex]radius = 7.5 \: \: units[/tex]
