Find the distance between the two points in simplest radical form.
(-9,8) and (-3, -1)
Answer:
The distance between (-9, 8) and (-3, -1) will be:
[tex]\:d=3\sqrt{13}[/tex] units
Step-by-step explanation:
Given the points
(-9, 8)(-3, -1)Finding the distance between (-9, 8) and (-3, -1)
[tex]d\:=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
[tex]=\sqrt{\left(-3-\left(-9\right)\right)^2+\left(-1-8\right)^2}[/tex]
[tex]=\sqrt{\left(-3+9\right)^2+\left(-1-8\right)^2}[/tex]
[tex]=\sqrt{36+81}[/tex]
[tex]=\sqrt{117}[/tex]
[tex]=3\sqrt{13}[/tex] units
Therefore, the distance between (-9, 8) and (-3, -1) will be:

Answer:
a) -1
Step-by-step explanation:
Slope is also known as the gradient
1. assign a value to x and solve for y:
when x = 2, y = 2
when x = 4, y = 0
2. Next, use the equation of a straight line to find the gradient
y = mx + c
y is the y-coordinate, m is the gradient, x is the x-coordinate, c is the point where the line crosses the y-axis, which is found by equating y to 0 and solving for x
so y = mx + c becomes 2 = m*2 + 4, which then becomes 2 = 2m + 4
2m = -2 (take 4 away from 2)
m = -1

The grocery store has 20% off from the original price on cereal. The equation for finding the sale price would be y = x - (.20x). What is the sale price if the cereal cost $3.00?
$2.20
$2.50
$2.40
$2.30
Step-by-step explanation:
y = x - 0.2x
y = 0.8x
When x = $3.00, y = (0.8)($3.00) = $2.40.
The sale price is $2.40.
Answer:
$2.40
Step-by-step explanation:
y = x - 20% of x
where x is $3.00
20% would be 1/5 of 3.00 = 3/5
3 - 3/5 = 15-3/5 = 12/5 = $2.40

Use quadratic regression to find the
equation for the parabola going
through these 3 points.
(2, 19) (6, 99) (-1, 1)
y=[?]^2+[?]x+[?]
Answer:
The standard form of the parabola is
y = 2 x² + 4 x + 3
Step-by-step explanation:
Step(i):-
The standard form of the parabola
y = a x² + b x + c ...(i)
The equation for the parabola is passing through the point (2 , 19 )
19 = 4a + 2b +c ...(ii)
The equation for the parabola is passing through the point (6 , 99 )
99 = 36a + 6b +c ...(iii)
The equation for the parabola is passing through the point (-1,1) )
1 = a - b + c ...(iv)
step(ii):-
subtracting (ii) and (iii) , we get
8a + b = 20 ...(a)
Subtracting (iii) and (iv) , we get
5a + b = 14 ...(b)
solving (a) and (b) , we get
subtracting (a) and (b) , we get
8a + b-( 5a + b ) = 20 - 14
3 a = 6
a = 2
substitute a=2 in equation (a) , we get
8a + b = 20
8(2) + b = 20
b =20 -16
b = 4
Substitute a= 2 ,b = 4 in equation (ii) , we get
19 = 4a + 2b +c
19 = 8 + 8 + C
c = 19 -16 = 3
Final answer:-
The standard form of the parabola is
y = 2 x² + 4 x + 3
What is the answer to this?
Answer:
The value of x = -22
Step-by-step explanation:
Given the expression
[tex]-0.57x+0.27x=6.6[/tex]
Add similar elements: [tex]-0.57x+0.27x=-0.3x[/tex]
[tex]-0.3x=6.6[/tex]
Multiply both sides by 10
[tex]-0.3x\cdot \:10=6.6\cdot \:10[/tex]
Refine
[tex]-3x=66[/tex]
Divide both sides by -3
[tex]\frac{-3x}{-3}=\frac{66}{-3}[/tex]
[tex]x=-22[/tex]
Therefore, the value of x = -22
In a fruit punch drink, the 3 ingredients are apple juice, orange juice and cranberry juice. If 1/4 of the drink is apple juice and 3/10 is orange juice then write the ratio of cranberry juice to apple juice to orange juice in its simplest form.
Answer:
5 : 6 : 9Step-by-step explanation:
The drink has 3 ingredients
Apple juice = 1/4 = 25%Orange juice = 3/10 = 30%Cranberry juice = the rest = 100% - (25% + 30%) = 45%The ratio is:

5 : 6 : 9Choose the polynomial that is described. A trinomial in one variable of degree 3.a. 4r2-9t+7b. 3r2+4t-9 c. 4r3 d. 4r3 -9t +7
Answer:
C. 4r³
Step-by-step explanation
A trinomial is an expression having three terms. A polynomial with degree 3 that which its leading variable has a power of 3. For example an example of such polynomial in one variable is expressed as 2x³+4x²-7. This equation has 3 terms and the leading variable has a power of 3 with only x as the variable
From the given options based on the explanation, the correct answer will be 4r³. This can also be written as a trinomial as 4r³+0r²+0r
The rest contains more than one variable.
There is no trinomial.
A trinomial is a polynomial with three nonzero terms
Here we have to find trinomial in one variable of degree 3 .
Since in given four options a , b , d have equations in two variables and c have only one term so there is no trinomial.

A hospital wants to survey religious participants in their city about what they seek from a hospital chaplain, so
they randomly select 5 religious meetings in the city and survey every participant in those meetings.
What type of sample is this?
Using sampling concepts, it is found that this is an example of cluster sampling.
Samples may be classified as:
Convenient: Drawn from a conveniently available pool. Random: All the options into a hat and drawn some of them. Systematic: Every kth element is taken. Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed. Stratified: Also divides the population into groups. However, only some elements of each group are surveyed.In this problem, each religious meeting is a group, and all participants are surveyed, hence, we have an example of cluster sampling.

O A. It is not a function.
OB. It fails the vertical line test.
O C. It is a one-to-one function.
O D. It is a many-to-one function.
pls help!!
Answer:
D. It is a many-to-one functionStep-by-step explanation:
One-to-one if every y value has exactly one x value mapped onto itMany-to-one if there are y values that have more than one x value mapped onto them.We have a function that is of degree 3, so it has 3 x-intercepts which means there are points (x₁, 0), (x₂, 0), (x₃, 0), so it is a many-to-one function
Correct option is D
Explain how the applications of inventory management for fixed quantities differ from those for fixed time periods. Give specific instances in which you would use a fixed time period model rather than a fixed quantity model. Provide real-world examples.
Answer:
The main difference between the fixed quantity and fixed time period is that the fixed quantity makes it mandatory for a fixed number of items to be ordered every time an order is made, while the fixed time period has a fixed period orders are received before the next order period.
Step-by-step explanation:
The fixed quantity model is adopted by producers of a product to maintain a package type and also to maximize the profit derived from sales. For example is when ordering or buying eggs from a store, the buyer cannot purchase five eggs since it is packaged in a dozen (12), and so must buy the whole package.
The fixed time model uses time intervals to receive and accumulate orders before delivery is made for every order interval.
