How do you solve for X and A?
9514 1404 393
Answer:
3. x = 10
4. a = 8
Step-by-step explanation:
A reasonably simple rule to remember for secants outside the circle or chords inside the circle: the product of the lengths from the point of intersection of the lines to the points of intersection of the circle is the same for each line.
When the external line is tangent to the circle, the two points of intersection of the line with the circle are the same: the point of tangency. Effectively, this means the length is squared.
__
3. For line QP, the product is 3(3+5) = 24.
For line QR, the product is 2(2+x). The rule above says these are equal:
24 = 2(2+x)
12 = 2+x . . . . . divide by 2
10 = x . . . . . . . subtract 2
__
4. For line BC, the product is (a)(a) = a^2.
For line GC, the product is 4(12+4) = 64. The rule above says these are equal:
a^2 = 64
a = √64 . . . . take the square root
a = 8

A) y=(x - 7)(3x + 4)
B) y = (x – 7)(4x + 3)
C) y = (x + 7)(4x – 3)
D) y = (x + 7)(3x - 4)
9514 1404 393
Answer:
B) y = (x -7)(4x +3)
Step-by-step explanation:
For zeros p and q, factors of the function are (x -p) and (x -q).
For the given zeros, the factors are (x -7) and (x -(-3/4)). By multiplying the latter by 4, we can eliminate the fraction.
y = (x -7)(4x +3)

Steve has at most $80 to spend at a store. He wants to buy a movie that costs $22. He also wants to buy DVDs that cost $7.00 each. What is the maximum number of DVDs Steve can buy? write an inequality
Answer:
80 is less than or equal to 22+7x
8 DVDs
Step-by-step explanation:
I don't have the inequality signs sorry if you don't know its the symbol thats opening to the left with a line underneath
80 is less than or equal to 22+7x
subtract 22
58 is less than or equal to 7x
divide and flip the sign to the right
x is greater than or equal to 8.29
so he can buy 8 DVDs in total

For each carbon-14 atom, there are approximately 10^12 carbon-12 atoms. This ratio is constant in each organism. The carbon-12 remains constant but the carbon-14 decays. Suppose a piece of wood is analysed, and it contains 10^14 carbon-12 atoms and 40 carbon-14 atoms.
1) Determine how many carbon-14 atoms were present in the wood when it died.
2) Use the half life of carbon-14 atoms to obtain a function to model the number N of carbon-14 atoms present in the wood (t) years after it died
Answer:
1) There are 100 carbon-14 atoms in the wood when it died
2) A function that models the number 'N' of carbon-14 atoms present in the wood (t) years after it died is presented as follows;
[tex]N = 100 \times \left (\dfrac{1}{2} \right )^{\dfrac{t}{5,730} }[/tex]
Step-by-step explanation:
The given parameters are;
The number of carbon-12 for each carbon-14 atom ≈ 10¹² carbon-12 atoms
The number of carbon-12 in the piece of wood = 10¹⁴ carbon-12 atoms
The number of carbon-14 in the piece of wood = 40 carbon-14 atoms
The number of carbon-12 in an organism = Constant
The number of carbon-14 in an organism = Decays
1) Given that the number of carbon-12 in an organism is constant, and there are 10¹² carbon-12 atoms per each carbon-14 atom, therefore, we have;
The number of carbon-12 atoms in the wood when it died = 10¹⁴ carbon-12 atoms
The number of carbon-14 atoms in the wood when it died = (10¹⁴ carbon-12 atoms)/(10¹² carbon-12 atoms/(carbon-14 atom)) = 100 carbon-14 atoms
The number of carbon-14 atoms in the wood when it died = 100 carbon-14 atoms
2) The half life of a radioactive isotope is given by the following formula;
[tex]N(t) = N_0 \cdot \left (\dfrac{1}{2} \right )^{\dfrac{t}{t_{\frac{1}{2} }} }[/tex]
The half life of carbon-14 atoms, [tex]t_{\frac{1}{2} }[/tex] ≈ 5,730 years
N₀ = The amount of carbon-14 present in the wood when it died = 100 carbon-14 atoms
Therefore, we have;
The number, N, of carbon-14 atoms present in the wood (t) years after it died is given as follows;
[tex]N = 100 \times \left (\dfrac{1}{2} \right )^{\dfrac{t}{5,730} }[/tex]

The fact family model represents 3 + 14 = 17. A triangle. 17 is in the top corner. 3 is in the bottom left corner. 14 is in the bottom right corner. How does 17 compare to 3? 14 is 17 less than 3. 3 is 14 less than 17. 3 is 17 greater than 14. 3 is 14 greater than 17.
Answer:
3 is 14 less than 17
Step-by-step explanation:
Given the model:
3 + 14 = 17
Say :
A = 17
B = 3
C = 14
Comparing 3 to 17 in the model :
We can express 17 interms of 3 and 14
3 + 14 = 17
17 is the sum of 3 and 14
Therefore, 17 is 3 greater than 14 or 14 greater than 3
14 = 17 - 3
14 is 3 less than 17
3 = 17 - 14
3 is 14 less than 17
From the options , the correct statement which models the comparison between 17 and 3 is ;
"3 is 14 less than 17".
What is an equation of a the line through (-1, -4) and parallel to the line 3x+y=5
Answer: y + 4 = -3(x+1)
Step-by-step explanation:
We need to rewrite in form of y=mx+b.
3x+y=5
y = -3x + 5
The slope is -3.
In addition, the slope of two parallel line would be equal, the slope of the line would be -3.
y- y1 = m(x- x1)
y- (-4) = -3(x - -1)
y + 4 = -3(x+1)

Find the mistake and show the correct steps and solution
Answer:
The mistake happens in the 4th line.
Step-by-step explanation:
The first 3 lines are correct until the 4th line which is 2=6x. This is wrong. If we go back a line to the third line, it is 22=-20+6x. The part that was wrong was that they subtracted 20 from 22 to get 2. We are supposed to add 20 to each side because the -20 is negative. So the 4th line should be 42=6x. Then, we know that 6 times 7 is 42, so x is equal to 7.
22 + 53x + x = -20 + 60x
22 + 54x = -20 + 60x
22 = -20 + 6x
42 = 6x
x = 7

Part A: The Sun produces 3.9 ⋅ 1033 ergs of radiant energy per second. How many ergs of radiant energy does the Sun produce in 1.55 ⋅ 107 seconds? Express your answer in scientific notation and show your work. (5 points)
Part B: Which is the more reasonable measurement of the distance between the tracks on a CD:
1.6 ⋅ 10−3 mm or 1.6 ⋅ 103 mm? Justify your answer. (5 points)
Answer:
A. The answer is 165.85. B. The best answer is 1.435 ·103 because while they both are really small for a rail road track that one is bigger. the final answer for that is 147.805mm.
Step-by-step explanation:
(3.9 x 10³³) / 1 = X / (2.45 x 10⁵) .
Solve that proportion for ' X ' in the usual way.
If you can't remember how to solve a proportion, then
THAT's what you have to go look up. It's much more
important to you right now than how much energy the
sun is putting out.

If the tracks on a DVD were that far apart, there would not be
room for very many tracks on a DVD. That's not reasonable.
If the tracks are 7.4 x 10⁻⁴ mm apart, then there are about
34,000 tracks in a stripe that's 1-inch wide. I have no idea
how they do this, but it's certainly more reasonable than the
other choice. Hope this helps! Can you please give me Brainleist?
