We have a right triangle with legs of 12 and 5. The hypotenuse is x
Use the pythagorean theorem to find x
a^2 + b^2 = c^2
5^2 + 12^2 = x^2
25 + 144 = x^2
169 = x^2
x^2 = 169
x = sqrt(169)
x = 13
The hypotenuse of this right triangle is 13 units, so this is the distance between the two points.

1.) A jar contains 4 red, 5 white, and 3 blue marbles. A marble is drawn from the jar. What is the probability that the marble is
Blue?______ White?_____ Red?_____ Not red?_____
Answer:
P ( blue ) = 1/4
P ( white ) = 5/12
P ( red ) = 1/3
P ( not red ) = 2/3
Step-by-step explanation:
To find the probability of a marble being chosen, it is the number of that color over the total
We need to find the total number of marbles
4 red+ 5 white+3 blue = 12 marbles
P ( blue ) = 3 blue / 12 total = 3/12 = 1/4
P ( white ) = 5 white / 12 total = 5/12
P ( red ) = 4 red/ 12 total = 4/12 = 1/3
How man marbles are not red
total marbles - red marbles = 12-4 = 8
8 marbles are not red
P ( not red ) = 8 not red / 12 total = 8/12 = 2/3
Divide the following polynomial, then place the answer in the proper location on the grid. Write your answer in order of descending powers of x.
(a^2n - a^n - 6) ÷ (a^n + 8)
The correct answer for dividing [tex](a^{2n} - a^n - 6) by (a^n + 8)[/tex] is indeed:
[tex](a^n - 9) + (-78)/(a^n + 8).[/tex]
Let's divide the given polynomials:
[tex]\frac{a^{2n -a^n -6}}{a^n +8}[/tex]
Here's the breakdown of the solution:
Factoring: We can factor the numerator [tex](a^{2n} - a^n - 6)[/tex] using difference of squares:
[tex](a^{2n} - a^n - 6) = (a^n)^2 - (a^n) - 6 = (a^n + 2)(a^n - 3)[/tex]
Division: Now, we can divide the factored numerator by the denominator:
[tex][(a^n + 2)(a^n - 3)] / (a^n + 8) = (a^n + 2) - [(a^n + 8) * (a^n - 3)] / (a^n + 8) = (a^n + 2) - (a^n - 3) = a^n - 9[/tex]
Remainder: Since the degree of the numerator is less than the degree of the denominator, we get a non-zero remainder.
This remainder is obtained by dividing the constant term (-6) in the numerator by the constant term (8) in the denominator, resulting in [tex]-78/(a^n + 8).[/tex]
Therefore, the final answer is [tex](a^n - 9) + (-78)/(a^n + 8)[/tex], with a quotient of [tex](a^n - 9)[/tex] and a non-zero remainder of [tex](-78)/(a^n + 8).[/tex]

The line with equation a+2b=0 coincides with the terminal side of an angle 0 in standard position and cos 0 < 0. What is the value of sin0?
Question:
line x + 2y = 0 is end side of angle θ
and cos θ < 0
Answer: sin θ = √5/5
Step-by-step explanation:
cos θ < 0 means x < 0
Line is y = -x/2, slope -1/2
Line intersects unit circle when x^2+y^2=1
x^2 + (-x/2)^2 = 1
x^2 + x^2/4 = 1
5x^2/4 = 1
x = -√(4/5) = -2√(1/5) = -2√5/5
y = √5/5
x^2 = 4/5, y^2 = 1/5
sin θ is y value at intersection of line and unit circle, √5/5
In this exercise we have to use the given equation and thus calculate the intersection value:
[tex]sin (\theta) = \sqrt{5/5}[/tex]
So knowing that you were informed:
Line x + 2y = 0 is end side of angle θ and cos θ < 0 means x < 0. Line is y = -x/2, slope -1/2 and the Line intersects unit circle when :
[tex]x^2+y^2=1\\x^2 + (-x/2)^2 = 1\\x^2 + x^2/4 = 1\\5x^2/4 = 1\\x = -\sqrt{4/5} = -2\sqrt{1/5} = -2\sqrt{5/5}\\y = \sqrt{5/5}\\x^2 = 4/5, y^2 = 1/5[/tex]
[tex]sin(\theta)[/tex] is y value at intersection of line and unit circle, [tex]\sqrt{5/5}[/tex]

Adam goes to the grocery store to buy cereal. the shelves contain 9 boxes of Brand A and 6 boxes of Brand B. He selects one brand at random and then put it back. Another person does the same thing. What is the probability they both selected Brand A?
We can first find the probability of the first person picking Brand A, which would be:
9/6+9
=9/15
=3/5
We can then find the probability of the second person choosing brand A:
(9-1)/(6+9-1)
=8/14
To find the probability they both select Brand A, we could multiply them together:
3/5 x 8/14

(x-2) is a factor since remainder is 0.
Step-by-step explanation:
We divide (x-2) into the polynomial [tex]-4x^4+6x^3+8x^2-6x-4[/tex] through long division or synthetic. We choose long division and look for what will multiply with (x-2) to make the polynomial [tex]-4x^4+6x^3+8x^2-6x-4[/tex] .
[tex](x-2)(-4x^3)=-4x^4+8x^3[/tex]
We subtract this from the original [tex]-4x^4-(-4x^4)+6x^3-(8x^3)+8x^2-6x-4[/tex].
This leaves [tex]-2x^3+8x^2-6x-4[/tex]. We repeat the step above.
[tex](x-2)(-2x^2)=-2x^3+4x^2[/tex].
We subtract this from [tex]-2x^3-(-2x^3)+8x^2-(4x^2)-6x-4=4x^2-6x-4[/tex]. We repeat the step above.
[tex](x-2)(4x)=4x^2-8x[/tex].
We subtract this from [tex]4x^2-(4x^2)-6x-(-8x)-4=2x-4[/tex]. We repeat the step above.
[tex](x-2)(2)=2x-4[/tex].
We subtract this from [tex]2x-(2x)-4-(4)=0[/tex]. There is no remainder. This means (x-2) is a factor.
The remainder R when the polynomial p(x) = -4x4 + 6x3 + 8x2 - 6x - 4 is divided by (x - 2) is 0, indicating that (x - 2) is indeed a factor of p(x).
Explanation:To find the remainder R when the polynomial p(x) = -4x4 + 6x3 + 8x2 - 6x - 4 is divided by (x - 2), we can use the Remainder Theorem. The Remainder Theorem states that the remainder of the division of a polynomial p(x) by a linear term (x - a) is equal to p(a). Therefore, to find R, simply calculate p(2).
p(2) = -4(2)4 + 6(2)3 + 8(2)2 - 6(2) - 4
p(2) = -4(16) + 6(8) + 8(4) - 12 - 4
p(2) = -64 + 48 + 32 - 12 - 4
p(2) = 0
Since the remainder is 0, this means that (x - 2) is a factor of p(x).
The correct answer is therefore R = 0, and yes, (x - 2) is a factor of p(x).

In mathematics a geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number, meaning when you graph it the line should be linear. Of all of these A is the only that is Linear the others are not. The slope of line A is 2 and the Y-intercept is 3.
Find the ratio of the volume of one sphere to the volume of the right cylinder
Answer:
B
Step-by-step explanation:
Let [tex]r[/tex] be the radius of one sphere.
Volume of sphere is [tex]V=\frac{4}{3}\pi r^3[/tex]Since radius is r, the height of the cylinder will be [tex]4r[/tex]
Also, the cylinder has the same radius as the sphere: [tex]r[/tex]
Plugging in the values we get: [tex]V=\pi (r)^{2}(4r)=4\pi r^3[/tex]
Ratio of volume of 1 sphere to volume of cylinder is:
[tex]\frac{\frac{4}{3}\pi r^3}{4\pi r^3}=\frac{\frac{4}{3}}{4}=\frac{4}{3}*\frac{1}{4}=\frac{1}{3}[/tex]
The ratio is 1:3

Isabelle wants to buy a bicycle. She has saved $9.76.Her mom tells her she needs 8 times more than amount. How much money does she need to buy a bicycle.
Answer:
$68.32
Step-by-step explanation:
Is 9.76 = x
And the value needed is 8 * this amount, then it can be shown with 8x
8x = 9.76 * 8
8x = 78.08
So the total price is $78.08
To find the money needed, simply subtract the saved money from this amount:
78.08 - 9.76 = 68.32
So she needs $68.32!
Isabelle needs $78.08 to buy the bicycle, which is 8 times her current savings of $9.76.
Explanation:Isabelle's current savings stands at $9.76. But she needs to have 8 times this amount in order to buy the bicycle. Mathematically speaking, you find how much she needs by multiplying her current savings by 8. So, $9.76 x 8 equals $78.08. Therefore, Isabelle needs a total sum of $78.08 to buy the bicycle.

Answer:
The game costs 32 dollars total, we know this because if you divid 32 by 4 its 8 and . if you multiply 8 times 3 its 24
Step-by-step explanation:
The total cost of the game is $32, calculated using the concept of fractions in mathematics where the given $24 was considered as three-fourths of the total game cost.
Explanation:The subject of the question involves the concept of fractions in mathematics. Here the information provided states that $24, which Ivanna has saved, represents three-fourths (or 3/4) of the total cost of the game. To find out the total cost of the game, we will consider the $24 as three parts, and we need to find out the value of one part (or one-fourth). So, we divide $24 by 3, which gives us $8. This $8 is one-fourth of the total game cost. Now, to get the total cost, we will multiply this one-fourth value ($8) by 4. So, the total cost of the game is $8 * 4 = $32.
