Answer:
x = 15
Step-by-step explanation:
A full circle = 360°
Therefore,
(8x - 10)° + (6x)° + (10x + 10)° = 360°
Solve for x
8x - 10 + 6x + 10x + 10 = 360
Add like terms
24x = 360
Divide both sides by 24
x = 360/24
x = 15

The circumference of a circle is 18.84 inches. What is the circle's diameter?
Answers
6 inches
Answer:
6
Step-by-step explanation:
The circles diameter is 6 because circumference is found when you do pi x diameter and since 18.84 ÷ 3.14 = 6 that means our diameter is 6

PLEASE HELP WITH THIS GEOMETRY ASSIGNMENT... IT WOULD MEAN A LOT BEING IT'S HALF MY GRADE... AND PLEASE EXPLAIN IT SO I CAN FINALLY UNDERSTAND OR IF YOU DONT WANT TO GIVE ME THE ANSWER JUST TELL ME HOW TO DO IT. THIS IS FORM IS FROM PLATO OR EDMENTRUM IF YOU WILL.L...
Question 2
The vertex form of the equation of a horizontal parabola is given by , x=1/4p(y-k)2+h where (h, k) is the vertex of the parabola and the absolute value of p is the distance from the vertex to the focus, which is also the distance from the vertex to the directrix. You will use GeoGebra to create a horizontal parabola and write the vertex form of its equation. Open GeoGebra, and complete each step below.
Part A
Mark the focus of the parabola you are going to create at F(-5, 2). Draw a vertical line that is 8 units to the right of the focus. This line will be the directrix of your parabola. What is the equation of the line?
Part B
Construct the line that is perpendicular to the directrix and passes through the focus. This line will be the axis of symmetry of the parabola. What are the coordinates of the point of intersection, A, of the axis of symmetry and the directrix of the parabola?
Part C
Explain how you can locate the vertex, V, of the parabola with the given focus and directrix. Write the coordinates of the vertex.
Part D
Which way will the parabola open? Explain.
Part E
How can you find the value of p? Is the value of p for your parabola positive or negative? Explain.
Part F
What is the value of p for your parabola?
Part G
Based on your responses to parts C and E above, write the equation of the parabola in vertex form. Show your work.
Part H
Construct the parabola using the parabola tool in GeoGebra. Take a screenshot of your work, save it, and insert the image below.
Part I
Once you have constructed the parabola, use GeoGebra to display its equation. In the space below, rearrange the equation of the parabola shown in GeoGebra, and check whether it matches the equation in the vertex form that you wrote in part G. Show your work.
Part J
To practice writing the equations of horizontal parabolas, write the equations of these two parabolas in vertex form:
focus at (4, 3), and directrix x = 2
focus at (2, -1), and directrix x = 8
equation is below...

Answers
Answer:
slope=-9/2
y int- 6
Step-by-step explanation:
okay lets take two points
-2,15 and -6,33
the slope is 33-15/ -6-(-2)= 18/-4=-9/2
equation is y=mx+b where m is slope and b is y intercept
so plugging values in we get
15=-2(-9/2)+b
15=9+b
b=6

during 3 days joy the cat was catching mice .Each day joy caught 3 mice more than the previous day .On the third day joy caught twice as many mice as on the first day . In total
how many mice did joy catch during the three days
Answers
Answer: 27
Step-by-step explanation:
Given
During 3 days the cat was catching mice
Suppose the first-day joy caught x mice
So, on the second day, it is x+3
on the third day, joy catches twice as many mice as on the first day i.e. 2x
or we can also write, no of mice caught on the second day plus 3 is equal to no of mouse caught on the third day
[tex]\Rightarrow x+3+3=2x\\\Rightarrow x=6[/tex]
In three day time, it is
[tex]\Rightarrow x+x+3+2x\\\Rightarrow 4x+3\\\Rightarrow 4\times 6+3=27[/tex]
