Answer:
The first 8 letters of the alphabet are:
{A, B, C, D, E, F, G, H}
To find the number of permutations, we can think of 8 positions. In each one of these positions, we can put one of the letters, now we need to find the number of possible options for each one of these positions, the total number of permutations will be equal to the product between all of these options.
Now, taking one letter at a time (to assign at each position)
For the first position, we have 8 options.
For the second position, we have 7 options (because one letter is already taken)
For the third position, we have 6 options (because two letters are already taken, one in the first position and another in the second)
For the fourth position, we have 5 options.
For the fifth position, we have 4 options.
For the sixth position, we have 3 options.
For the seventh position, we have 2 options.
For the last position, we have 1 option.
Then the total number of permutations is:
P = 8*7*6*5*4*3*2*1 = 40,320

According to the diagram below, which similarity statements are true?
Check all that apply.
R
The triangles ΔABC ≈ ΔBDC and ΔABC ≈ ΔADB are similar triangles. Then the correct options are B and C.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
In a right-angle triangle, the measure of one angle will be 90 degrees.
If any two angle of the triangles are congruent, then the triangles will be a similar triangle.
In triangle ΔABC and ΔADB, we have
∠A = ∠A (common angle)
∠B = ∠D = 90° (right angle)
Then the triangle ΔABC and ΔADB are similar triangles.
In triangle ΔABC and ΔBDC, we have
∠C = ∠C (common angle)
∠B = ∠D = 90° (right angle)
Then the triangle ΔABC and ΔBDC are similar triangles.
Then the correct options are B and C.
The diagram is given below.

find the slope for (3,-6)(-1,4)
show the steps
Answer:
y= -5/2x + 3/2
Step-by-step explanation:
(3,-6). y=mx+b or -6=-5/2 × 3+b, or solving for b: b=-6-(-5/2)(3). b=3/2.
(-1,4). y=mx+b or 4=-5/2 × -1+b, or solving for b: b=4-(-5/2)(-1). b=3/2.
Plugging in the two points, hence y= -5/2x + 3/2

How would I get the slope of this triangle?
Answer:
-4/3
Step-by-step explanation:
if the triangle is anchored at (0, 0) you come down
from point ( 0, 48) to point ( 36, 0) so the slope is
y= rise/run = -48/ 36 = -4/3
the volume in a tank varies periodically. At t=0 is at its maximum of 520 gallomns and at t=6 it is at its miximum of 170 gallons. A function in the form y=Acos(Bx)+C can be used to model this situation.Based on the information given determine the values of A,B and C
Answer:
A = 175, B = π/6, C = 345
Step-by-step explanation:
The given variation of the volume in the tank and time includes are;
At t = 0 the volume in the tank, y = Maximum volume, [tex]y_{max}[/tex] = 520 gallons
At t = 6 the volume in the tank, y = Minimum volume, [tex]y_{min}[/tex] = 170 gallons
The function that models the situation is y = A·cos(B·x) + C
Given that the function that models the situation is the cosine function, we have;
A = The amplitude = (The maximum - The minimum)/2
∴ A = (520 - 170)/2 = 175
A = 175
The period = The time to change from maximum to minimum = 2 × The time to change from maximum (t = 0) to minimum (t = 6)
∴ The period = 2 × (6 - 0) = 12
The period = 12 seconds = 2·π/B
∴ B = 2·π/12 = π/6
B = π/6
C = The vertical shift = Th minimum + A = (The maximum + The minimum)/2
∴ C = (520 + 170)/2 = 345
C = 345

A sock drawer contains winter socks and summer socks. Both varieties come in two colors: white and black. There is a pair of each combination. If a sock is selected randomly, what is the probability it will be a black sock or a summer sock? A. 0.25 B. 0.5 C. 0.625 D. 0.75
Answer:
D 0.75
Step-by-step explanation:
There are a total of 4 pairs: White-Summer, Black-Summer, White-Winter, and Black-Winter. There are a total of 8 socks.
The probability of pulling a black sock or a summer sock is the number of all black or summer socks divided by the total number of socks.
The number of black or summer socks includes 1 pair of White-Summer, 1 pair of Black-Summer, and 1 pair of Black-Winter.
This makes for 6 black or summer socks.
Divide 6 by 8 to get 0.75

Please help with problem and show work
Answer:
x = 7
Step-by-step explanation:
The image below shows the relationship between secants chords and tangents.
Imagine that the letters in the image represent the numbers in the actually problem
E would equal 9
C would equal 12
and A would equal x
We would then use the same formula C² = E * ( E + A ) to solve for x , but once again instead of using letters we use the numbers in the problem
We would have 12² = 9( 9 + x )
we now solve for x
Step 1 simplify and distribute
12²=144
9 * 9 = 81
9 * x = 9x
we would then have 144 = 81 + 9x
step 2 subtract 81 from each side
144 - 81 = 63
81 - 81 cancels out
we now have 63 = 9x
step 3 divide each side by 9
63 / 9 = 7
9x / 9 = x
we're left with x = 7
