Chords AB and CD intersect as sho below. Find the length of CD. Please answer with work, and please, no links.
Answer:
39
Step-by-step explanation:
The chords are equal to eachother. First multiply their divided lengths together:
9(3x-9)=21(x+1)
27x-81=21x+21
x=17
CD= 21+x+1
21+17+1=39
CD= 39
Chords AB and CD intersect as shown in the given figure. The chords are equal to each other. The length of CD is 17.
What is the relation between the line perpendicular to the chord from the center of the circle?If the considered circle has center O and chord AB, then if there is perpendicular from O to AB at point C, then that point C is bisecting(dividing into two equal parts) the line segment AB.
Or
|AC| = |CB|
Chords AB and CD intersect as shown below.
The chords are equal to each other.
Therefore,
[tex]9(3x-9)=21(x+1)\\27x - 81 = 21x + 21\\\\27x - 21x= 81 + 21\\\\x= 17[/tex]
CD = 21 + x + 1
21 + 17 + 1 = 39
CD = 39

11. Keng creates a painting on a rectangular canvas with a width that is four inches longer
than the height, as shown in the diagram below.
L= h +4 and H = h
A. Write a polynomial expression, in simplified form, that represents the area of the
canvas.
Keng adds a 3-inch-wide frame around all sides of his canvas.
B. Write a polynomial expression, in simplified form, that represents the total area of the canvas and the frame.
Part A
Answer: h^2 + 4h-------------------
Explanation:
We multiply the length and height to get the area
area = (length)*(height)
area = (h+4)*(h)
area = h(h+4)
area = h^2 + 4h .... apply the distributive property
The units for the area are in square inches.
===========================================================
Part B
Answer: h^2 + 16h + 60-------------------
Explanation:
If we add a 3 inch frame along the border, then we're adding two copies of 3 inches along the bottom side. The h+4 along the bottom updates to h+4+3+3 = h+10 along the bottom.
Similarly, along the vertical side we'd have the h go to h+3+3 = h+6
The old rectangle that was h by h+4 is now h+6 by h+10
Multiply these expressions to find the area
area = length*width
area = (h+6)(h+10)
area = x(h+10) ..... replace h+6 with x
area = xh + 10x .... distribute
area = h( x ) + 10( x )
area = h( h+6 ) + 10( h+6 ) .... plug in x = h+6
area = h^2+6h + 10h+60 .... distribute again twice more
area = h^2 + 16h + 60
You can also use the box method or the FOIL rule as alternative routes to find the area.
The units for the area are in square inches.
The area of the canvas without the frame is h² + 4h and with frame is h²+16h+60.
What is an area?Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
Given that, Keng is painting on a rectangular canvas with a width that is four inches longer than the height,
w = h+4, height = h
Area = (length)x(height)
area = (h+4)x(h)
area = h(h+4)
area = h² + 4h
With the frame,
If we add a 3 inch frame along the border, then we're adding two copies of 3 inches along the bottom side. The h+4 along the bottom updates to h+4+3+3 = h+10 along the bottom.
Keng added a 3-inch-wide frame around the painting,
Therefore,
The h+4 will become h+4+3+3 = h+10
Similarly, along the vertical side = h+3+3 = h+6
Area = (h+10)(h+6) = h²+16h+60
Hence, the area of the canvas without the frame is h² + 4h and with frame is h²+16h+60.

Now,
Because it does not have an equal sign. It can be written as L + 6, where L is the number of minutes that Laura sang.
The sentence “Ken sang 6 minutes longer than Laura” is a situation that can be modeled by an equation, because it involves a relationship between two quantities. It can be written as K = L + 6, where K is the number of minutes that Ken sang and L is the number of minutes that Laura sang.

Find the measures of the exterior angles of the polygon.
Answer:
D : 125°,125°,55°,55°
Step-by-step explanation:
Finding the interior angles makes the question easier.
The two base angles for b1 are both 125°, and the two base angles for b2 are both 55°.
Because a straight line is 180°, we can find the exterior angles by subtracting the interior angles from 180°.
180°-55° = 125°
180°-125° = 55°
A teacher buys some pencils.

function of the number of students (x) he has?
Answer:
y=2x(.10)
Step-by-step explanation:
I think this is correct but it is 0.10 times 2 because it is 2 pencils/student and each pencil cost 10 cents. We multiply by x because we need to have 2 for each student

A standard American deck of cards contains 52 cards in four “suits”:
♣ clubs
♦ diamonds
♥ hearts
♠ spades
Each card also has a “rank”. There are 13 ranks: 2, 3, 4, 5, 6, 7, 8, 9, 10, J (jack), Q (queen), K (king), A(ace). Every suit-rank combination occurs in the deck, so a typical card might be called “the 7 of clubs” or “the queen of hearts”. Suppose we shuffle a deck (meaning that we put the cards in random order), then we draw a card
off the top. What is the probability that this card has an even number on it? (Jacks, queens, kings, and aces do not have numbers on them.)
I need the answer quickly pls
Answer:
5/13
Step-by-step explanation:
We can first start by finding the number of even numbers in one suit and then multiply by 4. The even numbers are:
2, 4, 6, 8, 10
There are 5, and since there are 4 suits, there is a total of 20 even cards.
Probability is equal to the amount of desirable outcomes over the total number of outcomes. The desirable outcomes are when we pull out an even number, and as we calculated earlier, there are 20 of those. There are 52 total cards, so that is the number of total outcomes. We get the expression:
20 / 52 which simplifies to 5/13

Using his telescope tommy watches a bald eagle as it sits ono top of a cliff. The telescope is positioned so that the line of sight to the eagle forms a 38 degree angle of elevation. The telescope sets s1.3 m above the ground and the base of the telescope is 116 m from the base of the cliff. Round to the nearest tenth
Question :
How high above the ground is the eagle?
Answer:
91.9 m
Step-by-step explanation:
From the diagram :
We can obtain h, using the trigonometric relation :
Tanθ = opposite / Adjacent
Opposite = h
Adjacent = 116
Tan 38° = h / 116
0.7812856 = h / 116
h = 0.7812856 * 116
h = 90.629132
Eagle's height above the ground :
h + 1.3m
h = 90.629132m
Height above the ground = 90.629132 + 1.3 = 91.9 m above the ground.
