Answer:
Zeros → (-2, 0) and (4, 0)
Step-by-step explanation:
Equation of the graph has been given as,
y = [tex]\frac{1}{2}x^{2} -x-4[/tex]
For zeros of the function,
y = 0
Therefore, [tex]\frac{1}{2}x^{2} -x-4=0[/tex]
By solving the equation algebraically,
x² - 2x - 8 = 0
x² - 4x + 2x - 8 = 0
x(x - 4) + 2(x - 4) = 0
(x + 2)(x - 4) = 0
x = -2, 4
Therefore, coordinates of the zeros will be (-2, 0) and (4, 0).
Let's confirm the zeros (x-intercepts) from the graph attached,
Coordinates of the x-intercepts are,
(-2, 0) and (4, 0)

Angel and his 2 sisters shared 1/2 cup of baby carrots. How many cups did they each get?
Answer:
1/6 cup
Step-by-step explanation:
1/2 is to be split evenly between 3 people (Angel and his 2 sisters) so our equation is
1/2 ÷ 3 = 1/6
So, they each get 1/6 cup of baby carrots
Answer:
[tex]\frac{1}{6}[/tex] cups each.
Step-by-step explanation:
There is 1/2 of a cup of baby carrots available.
Angel and his 2 sisters would mean that there are 3 of them in all. Divide 1/2 with 3:
[tex]\frac{\frac{1}{2}}{3} = \frac{1}{2} * \frac{1}{3}[/tex]
Multiply across:
[tex]\frac{1}{2} * \frac{1}{3} = \frac{1}{6}[/tex]
Each person received [tex]\frac{1}{6}[/tex] of a cup.

Write an equation of the line that passes through the given points. (-1,7) and (3,-5)
Answer:
y=-3x+4
Step-by-step explanation:
First, let's find the slope (m)
(-1,7), and (3,-5)
the formula is: (y2-y1)/(x2-x1)
we can label the points.
x1=-1
y1=7
x2=3
y2=-5
substitute into the equation
m=(-5-7)/(3--1)
m=(-12)/4
m=-3
Now let's use the equation for point-slope form, which is y-y1=m(x-x1)
using the labeled points from above:
y-7=-3(x+1)
do distributive prop
y-7=-3x-3
add 7 to both sides
y=-3x+4

Scrat the squirrel has a few nuts. When he put them in groups of 5 nuts, two nuts were left, and
when he laid them out in groups of 3 nuts, there were no nuts left. How many nuts among the
options provided below could belong to Scrat?
Answer:
The options are not shown, so i will solve this in a general way.
Let's suppose that there are N nuts
If we divide the N nuts into groups of 5, there will be a remainder of 2 nuts.
If we divide the N nuts into groups of 3, there is no remainder.
This means taht N is a multiple of 3. then we can write:
N = 3*k
where k is a random integer.
Now, we know that when we divide N by 5, there is a remainder of 2 nuts, this means that N is equal to a multiple of 5 plus 2, then we can write:
N = 5*j + 2
where j is a random integer.
Now we only need to find a pair of k and j (both positive integers) such that:
3*k = 5*j + 2
We can rewrite this as:
k = (5/3)*j + (2/3)
Now we could just input different values of j, and see if k is also an integer:
j = 2
k = (5/3)*2 + 2/3 = 10/3 + 2/3 = 12/3 = 4
Then the pair j = 2, k = 4 is a possible solution.
N = 3*k = 3*4 = 12
N = 5*j + 2 = 5*2 + 2 = 12
From this we can conclude that N = 12, so Scrat has 12 nuts.
Now with the equation
k = (5/3)*j + (2/3)
We can find other possible combinations of j and k, that will give different values for N.
for example, if j = 5:
k = (5/3)*5 + 2/3 = 25/3 + 2/3 = 27/3 = 9
Then the pair j = 5, k = 9 is also a possible solution:
N = 3*k = 3*9 = 27
N = 5*j + 2 = 5*5 + 2 = 27
In this case, Scrat has 27 nuts.
Continuous variable expected to show a statistical relationship with dependent variables are called ____
Answer:
Instant Variables
Step-by-step explanation:
A continuous variable is a variable defined as one which can receive an infinite set of values.
This continuous variable has two types namely instant variables and ratio variables.
Instant variables are those in which the distance between each category is equal or static. Meanwhile, ratio variables are those in which the ratio between the given scores provide information in regards to the relationship between the responses/dependent variables.
Thus, the one that corresponds to our question are instant variables.

Soon may the Wellerman come
To bring us sugar and tea and rum
One day, when the tonguin' is done
We'll take our leave and go
She had not been two weeks from shore
When down on her a right whale bore
The captain called all hands and swore
He'd take that whale in tow
Soon may the Wellerman come
To bring us sugar and tea and rum
One day, when the tonguin' is done
We'll take our leave and go
Before the boat had hit the water
The whale's tail came up and caught her
All hands to the side, harpooned and fought her
When she dived down low
Soon may the Wellerman come
To bring us sugar and tea and rum
One day, when the tonguin' is done
We'll take our leave and go
No line was cut, no whale was freed
The Captain's mind was not of greed
And he belonged to the whaleman's creed
She took that ship in tow
Soon may the Wellerman come
To bring us sugar and tea and rum
One day, when the tonguin' is done
We'll take our leave and go
For forty days, or even more
The line went slack, then tight once more
All boats were lost, there were only four
But still that whale did go
Soon may the Wellerman come
To bring us sugar and tea and rum
One day, when the tonguin' is done
We'll take our leave and go
As far as I've heard, the fight's still on
The line's not cut and the whale's not gone
The Wellerman makes his regular call
To encourage the Captain, crew, and all
Soon may the Wellerman come
To bring us sugar and tea and rum
One day, when the tonguin' is done
We'll take our leave and go
Soon may the Wellerman come
To bring us sugar and tea and rum
One day, when the tonguin' is done
We'll take our leave and go
