Answer:
1) Center = A → centermost point of a circle.
2) Radius = AB, AC → distance from centre to any point on the surface of the circle.
3) Diameter = BC → longest chord; distance from 1 point of the circle to another which passes through the centre of the circle.
4) Chord = IH → distance from 1 point on the circle to another.
5) Tangent = GF → external line which passes through only 1 point of the circle.
6) Secant = DE → external line which passes through 2 points on the circle.

Answers
Step-by-step explanation:

G must be congruent to B (the vertexes with the right angle).
and then
GH = GF = CB = AB (they are both isoceles triangles meaning both legs have the same length, and then these legs must be congruent bergen the triangles, so, in fact, all 4 sides must have equal length).
therefore,
5y mm = 25 mm
y = 5
(2x + 5) mm = 25 mm
2x + 5 = 25
2x = 20
x = 10
(3z + 14) mm = 35 mm
3z + 14 = 35
3z = 21
z = 7

It’s usually used on triangles when two sides are given but one isn’t. C represents the hypotenuse while A and B are interchangeable. So solving for the hypotenuse would look like √a^2+ b^2= c but solving for a or be would look like √c^2-b^2 = a and √c^2-a^2= b.
So number wise √5^2+12^2 = 13

Area = [tex]16\sqrt{3}[/tex] square inches.Choice AChoice BLadder is 14 feet long.=========================================================
Explanation:
Problem 1
Focus on one of the triangles (they're identical copies of each other).
Each triangle is a 30-60-90 triangle.
The hypotenuse is 8 which cuts in half to 4 to be the short leg.
The long leg is [tex]\sqrt{3}[/tex] times that of the short leg, meaning the long leg is [tex]4\sqrt{3}[/tex] inches long.
The area is therefore length*width = [tex]4*4\sqrt{3} = 16\sqrt{3}[/tex] square inches.
------------------------------
Problem 2
For a 30-60-90 triangle, the short leg x doubles to 2x when getting the hypotenuse. Only choice A fits with this description when going from 2 to 4.
------------------------------
Problem 3
The legs of a 45-45-90 triangle are the same length. This narrows our answer choices to B and D. We can conclude the final answer is B since the hypotenuse is exactly [tex]\sqrt{2}[/tex] units longer compared to the leg length.
------------------------------
Problem 4
A 30-60-90 triangle forms.
The 60 degree angle is between the ladder and the horizontal ground. The 30 degree angle is placed up top. Opposite the 30 degree angle is the horizontal side, which is of length of 7 feet mentioned. Doubling this gets to 2*7 = 14 feet and it's the hypotenuse.

A company set aside a certain amount of money in the year 2000. The company spent exactly the same amount from that fund each year on perks for its employees. In 2003 , there was still $790,000left in the fund. In 2005, there was $702,000 left.
Let x be the number of years since 2000, and let y be the amount of money, in dollars, left in the fund that year. Use a linear equation to model the amount of money left in the fund after so many years.
The linear model’s slope-intercept equation is _____
In the year 2009, there was _____ left in the fund.
In the year _____, the fund will be empty.
Answers
Answer:
Linear Equation: y=-44000x+88922000
Year 2009: $526000
By year 2021, they have no more fund
Step-by-step explanation:
Slope formula is difference of y/difference of x. 79000-70200/2003-2005=
-88000/2=-44000.
To find the y intercept, x=0.
It should be year 0. 44000x2003=88132000+790000=88922000
Now put it into y=mx+b
y=-44000x+88922000
Plug in 2009.
It should equal 526000.

Since both are at the same rate, then ratio and proportion can be applied here
If $40000 = $860

Therefore the taxes which would be on $55000 is $1182.50

The amount of money in an account may increase due to rising stock prices and decrease due to falling stock prices. Emerson is studying the change in the amount of money in two accounts, A and B, over time.
The amount f(x), in dollars, in account A after x years is represented by the function below:
f(x) = 1,264(1.09)x
Part A: Is the amount of money in account A increasing or decreasing and by what percentage per year? Justify your answer. (5 points)
Part B: The table below shows the amount g(r), in dollars, of money in account B after r years.
r (number of years) 1,2,3,4.
g(r) (amount in dollars) 1,375, 1,512.50,1,663.75,1,830.13
Which account recorded a greater percentage change in amount of money over the previous year? Justify your answer.
Answers
Answer:
A) increasing by 9% each year
B) Account B
Step-by-step explanation:
[tex]f(x)=1264(1.09)^x[/tex]
Part A
The amount of money in account A is increasing by 9% each year.
General form of an exponential function: [tex]f(x)=ab^x[/tex]
[tex]a[/tex] is the initial value, [tex]b[/tex] is the growth factor and [tex]x[/tex] is time.
If b < 1 then the function is decreasingIf b > 1 then the function is increasingAs b = 1.09 > 1 then the function is increasing
[tex]b[/tex] is the decimal form of percentage change.
Therefore, for b > 1, percentage increase = b - 1
for b < 1, percentage decrease = 1 - b
So as b = 1.09 > 1, percentage increase = 1.09 - 1 = 0.09 = 9%
Part B
From inspection, the amount in account B is increasing exponentially.
Therefore, we can use [tex]y=ab^x[/tex]
To determine the growth factor [tex]b[/tex], divide one value of g(r) by its previous value:
[tex]\implies b=\dfrac{1512.50}{1375}=\dfrac{11}{10}=1.1[/tex]
[tex]\implies g(r)=a(1.1)^r[/tex]
To determine [tex]a[/tex], input a pair of values (r, g(r)) into the equation and solve:
[tex]\implies 1375=a(1.1)^1[/tex]
[tex]\implies a=\dfrac{1375}{1.1}=1250[/tex]
Therefore, the equation for account B: [tex]g(r)=1250(1.1)^r[/tex]
Comparing the growth factor [tex]b[/tex] of both equations, account B recorded a greater percentage change in amount of money over the previous year since 1.1 > 1.09
