Step-by-step explanation:
The midpoint is halfway between the line segment. First find the distance from the starting point to the midpoint.
2-1 = 1. So Since the midpoint is behind the start point, we are going backwards (moving to the left on the x axis).
So 1 space left from the midpoint is 1-1=0.
For y, the distance between the start and mid is 6 - -1 = 6+1 = 7 spaces. Then add 7 spaces to the midpoint value of 6, so 7+6 = 13. We moved upwards on the y axis.

80 middle-school students went on a field trip to watch a performance of Alice In Wonderland. When the teacher took a survey, 70% of the students responded that they enjoyed the play. About how many students enjoyed the play?
Answers
Answer:
56 students
Step-by-step explanation:
Because there are 80 students and only 70% enjoyed it, 70% is equal to 0.7 so you would multiply 80 by 0.7.
Is this a square root graph?
Is this graph a reflection of its parent graph?
this graph shifted _
The equation to this graph would transform the parent function f(x) to _
Answers
Answer:
Thus, [tex]y=-\sqrt{x+3}[/tex] represents the transformed graph on the attached figure, which is a translated square root graph i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.
Step-by-step explanation:
Consider the function
y = f(x)
The rule of horizontal translation
y = f(x-h)
When 'h' is positive, the function is shifted to the right.
When 'h' is negative, the function is shifted to the left.
The rule of implying vertical reflection across the x-axis
y = -f(x)
Applying the rule:
We know that the square root function is
[tex]y=\sqrt{x}[/tex]
We know that if the graph would be reflected across the x-axis, then
[tex]y=-\sqrt{x}[/tex]
We know that is horizontally translated or shifted 3 units to the left, it implies +
3 inside the radical implies. Then the transformed function becomes .
Please check the attached diagram. From the diagram,
The blue graph shows the parent function [tex]y=\sqrt{x}[/tex].The red graph shows the transformed function i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.Thus, [tex]y=-\sqrt{x+3}[/tex] represents the transformed graph on the attached figure, which is a translated square root graph i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.

What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
The equation of a line y = (1/2)x - 1
We will find some coordinates from the equation.
When x = 1,
y = 1/2 - 1
y = -1/2
When x = 2,
y = 1/2 x 2 - 1
y = 1 - 1 = 0
When x = 3,
y = 1/2 x 3 - 1
y = 3/2 - 1
y = 1/2
When x = 4.
y = 4/2 - 1
y = 2 - 1
y = 1

On a unit circle, the vertical distance from the x-axis to a point on the perimeter of the circle is twice the horizontal distance from the y-axis to the same point. What is sin of theta
Answers
Answer:
2/√5
Step-by-step explanation:
A unit circle is a circle of unit radius. This means that the radius of a unit circle is 1.
Let a represent the horizontal distance. Therefore the vertical distance = twice the horizontal distance = 2a
We can get the hypotenuse using Pythagoras theorem:
hypotenuse² = a² + (2a)²
hypotenuse² = a² + 4a²
hypotenuse² = 5a²
hypotenuse = √5a²
hypotenuse = a√5
sin(θ) = opposite / hypotenuse
sin(θ) = vertical distance / hypotenuse
sin(θ) = 2a / a√5
sin(θ) = 2/√5

The residents of a city voted on wether to raise property taxes. The ratio of yes votes to no votes was 8 to 5. If there was 6856 yes votes, what was the total number of votes
Answers
Answer:
The total number of votes cast in the election was 11,141.
Step-by-step explanation:
To determine the number of negative votes in the voting, taking into account that the ratio of votes between positive and negative is 8 to 5 and that there were 6,856 positive votes, it is necessary to perform the following calculation:
6.856 / 8 x 5 = X
857 x 5 = X
4.285 = X
Therefore, there were 4,285 negative votes in the election. So, since 4,285 + 6,856 equals 11,141, the total number of votes cast in the election was 11,141.
Sam bought a 7/8 -foot piece of wood to make some small boxes to hold his insect collection. He used 3/16 foot of wood for each box. Which equation can be used to show how many boxes Sam made?
Answers
Answer:
Number of small boxes Sam made = Total piece of wood bought / Piece of wood used for each small box
Step-by-step explanation:
Total piece of wood bought = 7/8 foot
Piece of wood used for each small box = 3/16 foot
Number of small boxes Sam made = Total piece of wood bought / Piece of wood used for each small box
= 7/8 foot ÷ 3/16 foot
= 7/8 × 16/3
= 7×16 / 8×3
= 112 / 24
= 4 16/24
= 4 2/3 small boxes
The equation is:
Number of small boxes Sam made = Total piece of wood bought / Piece of wood used for each small box

ted's company has recieved an order to print 10^6 pages. ted's company has 100 machines , each of which can print 10^4 pages a day. ted's company can print the 10^6 pages in blank.
in exponent form, this number of days can be represented as blank
Answers
Answer:
1 day ; 10^0
Step-by-step explanation:
Given that:
Order received = 10^6 pages
Number of machines = 100
Daily printing capability by each machine = 10^4
Hence, total output per day = (10^4) * 100 = 10^4 * 10^2 = 10^4+2 = 10^6
Number of days required = number of order / daily output
Number of days = 10^6 / 10^6 = 1
In exponent form:
10^6 / 10^6 = 10^6-6 = 10^0
Katie is purchasing plates and mugs for her house.
She would like to buy at least 8 items. Plates cost
$8 each and the mugs cost $7 each, and she plans
to spend no more than $112. Write a system to
model the situation and then solve.
Answers
Step-by-step explanation:
Plate: $8 each
Mug: $7 each
Spend Limit: $112
Items Wanted: 8
Considering she wants eight items, she can split that in half and buy four of each item, plate and mug.
8 * 4 = 32
$32 for 4 plates.
7 * 4 = 28
$28 for 4 mugs.
However, if she wanted to spend all the money, she could buy a few more of each item.

The vertex of a parabola is (3,-2) and another point on the parabola is (2,3) find the equation of the parabola in vertex form
Answers
Answer:
[tex]y = 5 ( x - 3 ) ^2 -2[/tex]
OR
[tex]y+2= 5 ( x - 3 ) ^2[/tex]
Step-by-step explanation:
Vertex form of a parabola is given as:
[tex]y = a ( x - h ) ^2 + k[/tex]
Where ([tex]h,k[/tex]) is the vertex and [tex](x,y)[/tex] are the points on the parabola.
We are given that, the vertex is (3, -2) and another point on parabola is given as (2, 3).
[tex]h = 3,k = -2[/tex]
First of all, putting the vertex in the vertex equation as given above:
[tex]y = a ( x - 3 ) ^2 + (-2)[/tex]
Now, putting the values of [tex]x, y[/tex] as 2, 3 and let us find the unknown variable [tex]a[/tex]:
[tex]3 = a ( 2 - 3 ) ^2 + (-2)\\\Rightarrow 3 = a -2\\\Rightarrow a = 5[/tex]
Therefore, the equation in vertex form can be written as:
[tex]y = 5 ( x - 3 ) ^2 -2[/tex]
OR
[tex]y+2= 5 ( x - 3 ) ^2[/tex]
