Exact form: -3/2
Decimal Form: -1.5
Step-by-step explanation:
Hello there!
We need to find out the slope of the given two coordinates/points, that are:
(0,6(8,-6)Solution:
We'll need to use the formulae that is used to find out the slope,that is:
[tex] \pink{\star}\boxed{\rm \: Slope = \cfrac{y_2 -y_1}{x_2 - x_1}} \pink{\star}[/tex]
According to this question,here:
[tex]\rm \blue{\star} (y_2 , y_1) = (-6 , 6) \blue{\star}[/tex][tex]\rm \blue{\star}(x_2 , x_1)= (8 , 0) \blue{\star}[/tex]So substitute them accordingly:
[Slope is denoted as m][tex] \rm \: m = \cfrac{ - 6 -( 6)}{8 - 0} [/tex]
Simplify using PEMDAS rule.
[tex] \rm \: m = \cfrac{ - 12}{8} [/tex]
-12/8 could be canceled.
[tex] \rm \: m = \cfrac{ - 6}{4} [/tex]
-6/4 could also be canceled.
[tex] \boxed{ \rm \: m = \cfrac{ - 3}{2} \: or \: - \cfrac{3}{2} }[/tex]
Or it could be represented as decimal:
[tex] \boxed{ \rm \: m = - 1.5}[/tex]
Hence , the slope m will be -3/2 or -1.5

find the radius of a circle whose arc length is 55 m and its central angle measure if 5 radians
Answer:
Step-by-step explanation:
To solve this question, we can use the formula [tex]S=\theta r[/tex], where [tex]S[/tex] is the arc length, [tex]\theta[/tex] is the central angle of the sector in radians, and [tex]r[/tex] is the radius.
In this situation, we know that [tex]S=55[/tex] and [tex]\theta=5[/tex]
This means that [tex]55=5r \longrightarrow \boxed{r=11}[/tex]

Answer: The correct answer is (-1, 2).
Step-by-step explanation: Find how many units the original F point is away from the center. It is 2 units away in terms of x, and 4 units away in terms of y. The x value has to be negative since the initial x point was already negative. -2/2 = -1. Hence, the x value is -1. 4/2 = 2. Hence, the y value is 2.

Which quadratic function in vertex form has a vertex at (3, 4) and passes through the point (7,-4)
Answer:
First option
Step-by-step explanation:
Given the following question:
We are being asked to find the quadratic function that has a vertex of (3, 4) and passes through the point (7, -4). Remember that the vertex of any parabola is the point on the top of the parabola, directly in the middle of the top of the function.
First option:
[tex]y=-\frac{1}{2} (x-3)^2+4[/tex]
(see photo below)
As you can see the function has a vertex of (3, 4) which means the point on the top of the parabola is (3, 4) or the vertex. It also passes through the point (7, -4) meaning the first option is your answer.
Hope this helps.

answer question below.
The speed of the Elvira is 6.545 miles per hour. Then the speed of the Altheia will be 0.545 miles per hour.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
Let the speed of the Elvira be x. Then the speed of the Altheia will be (x - 6).
Let the distance between the coffee shop and Elvira's house be d.
Then the distance between the coffee shop and Altheia's house will be (3.6 - d).
Then we have
x = d / 0.5 ...1
(x - 6) = (3.6 - d) / 0.6 ...2
In solving the equations 1 and 2, we have
x = 6.545 and d = 3.2725 miles
Then the speed of the Elvira is 6.545 miles per hour. Then the speed of the Altheia will be 0.545 miles per hour.

The number of players the team can bring to the tournament is 21
Writing and solving equationFrom the question, we are to write an equation that can be used to solve the number of players the team can bring to the tournament
From the given information,
The members of the softball team raised $1405.25 and they rented a bus for $822.50
∴ They have $1405.25 - $822.50 left
Also, they budgeted $27.75 per player for meals
Then, x, the number of players the team can bring to the tournament is
x = ($1405.25 - $822.50) ÷ $27.75
x = $582.75 ÷ $27.75
x = 21
Hence, the number of players the team can bring to the tournament is 21.

Answer: B. 2,448π units³
Step-by-step explanation:
We will use the formula for the volume of a cylinder to solve.
(The formula, put simplify, finds the area of the base circle and multiples by the height.)
V = πr²h
V = π(12)²(17)
V = (144)(17)π
V = 2,448π
The volume is 2,448π units³ which is option B for your problem.
Solution :
We have been provided with the height and radius and we need to calculate the volume of cylinder. So we would be using it's formula :
V = πr²hHere,
r is radius h is heightWe have :
height (h) = 17 radius (r) = 12Substituting the value :
>> V = π (12)² (17)
>> V = π (12 × 12) (17)
>> V = π × 144 × 17
>> V = π × 2448
>> V = 2448 π
Therefore :

Kevin works at a restaurant. He stacks glasses as shown. Let x be the number of glasses and f(x) be the height of the stack. If 5.5 inch glasses with 1.2 inch lips are stacked vertically, which table correctly models this situation?
The table that correctly models the linear equation is table A.
Which table correctly models this situation?
The first glass added will have a height of 5.5 inches, and then for each glass that we add, we are adding a height of 1.2 inches.
This means that the first value on the table must be 5.5 in.The second value must be 5.5 in + 1.2in = 6.7 in.The third value must be: 6.7in + 1.2in = 7.9 inAnd so on, so we have the linear relation:
y = 5.5in + x*1.2in
Where x is the number of glasses in the tower.
Then the table that correctly models this situation is table A.

The volume of the given pyramid is 64 cubic inches.
What is the volume of the pyramid?The volume of the pyramid is the product of one-third of the height and square of the base side length.
The volume of Pyramid A = (1/3)(side²)(height)
The volume of a square pyramid is equal to one-third of the product of the base’s area and the pyramid’s height. The formula is:
V = (1/3) × a² × h
where a is the length of the square base, and h is the height (or altitude).
We are given that;
h = 3 inch, a = 8 inch, and hypotenuse = 5 inch,
Now, we can plug in the values into the formula and get:
V = (1/3) × 8² × 3
V = (1/3) × 64 × 3
V= (64 x 3)/3
V = 64 inch³

Find the length of the following curve. If you have a grapher, you may want to graph the curve to see what it looks like.
y=1/27((9x^2)+(6))^3/2 ,from x=3 to x=6
The length of the curve [tex]y = \frac{1}{27}(9x^2 + 6)^\frac 32[/tex] from x = 3 to x = 6 is 192 units
How to determine the length of the curve?The curve is given as:
[tex]y = \frac{1}{27}(9x^2 + 6)^\frac 32[/tex] from x = 3 to x = 6
Start by differentiating the curve function
[tex]y' = \frac 32 * \frac{1}{27}(9x^2 + 6)^\frac 12 * 18x[/tex]
Evaluate
[tex]y' = x(9x^2 + 6)^\frac 12[/tex]
The length of the curve is calculated using:
[tex]L =\int\limits^a_b {\sqrt{1 + y'^2}} \, dx[/tex]
This gives
[tex]L =\int\limits^6_3 {\sqrt{1 + [x(9x^2 + 6)^\frac 12]^2}\ dx[/tex]
Expand
[tex]L =\int\limits^6_3 {\sqrt{1 + x^2(9x^2 + 6)}\ dx[/tex]
This gives
[tex]L =\int\limits^6_3 {\sqrt{9x^4 + 6x^2 + 1}\ dx[/tex]
Express as a perfect square
[tex]L =\int\limits^6_3 {\sqrt{(3x^2 + 1)^2}\ dx[/tex]
Evaluate the exponent
[tex]L =\int\limits^6_3 {3x^2 + 1} \ dx[/tex]
Differentiate
[tex]L = x^3 + x|\limits^6_3[/tex]
Expand
L = (6³ + 6) - (3³ + 3)
Evaluate
L = 192
Hence, the length of the curve is 192 units
