Plot the points O(0,0) R(1,4) C(−4, −1)and K(−4, 8)to form triangles ∆ORK and ∆OCK. Decide the relationship between m∡KOC and m∡KOR. Be sure to justify with any algebra and theorems !
Answer:
i think its c
Step-by-step explanation:
Complete the congruence statement by naming the corresponding angle or side.
50 points
Step-by-step explanation:
Triangles RQP and RBC are congruent.
Letters R and P are the 1st and 3rd letters in RQP.
Letters R and C are the 1st and 3rd letters in RBC.
Hence line RP = line RC = line CR (D).
D) CR
ΔRQP ≅ ΔRBC
They are congruent so if you highlight the line PR and find the similar one,
ΔRQP ≅ ΔRBC
The line would be line CR.
32/8 = 28/x
Please select the best answer from the choices provided
A: x = 4
B: x = 28
C: x = 8
D: x = 7
32/8=28/x
we multiply by x
x*32/8=28
we multiply by 8/32
x=28*8/32
8 divides by 32
x=28/4=7
D: x = 7
Answer:
D
Step-by-step explanation:
Given
[tex]\frac{32}{8}[/tex] = [tex]\frac{28}{x}[/tex] ( cross- multiply )
32x = 224 ( divide both sides by 32 )
x = 7 → D

What is an equation of the line that passes through the points (4,-2) and (8,3)?
Answer:
[tex]y-4=\frac{5}{4} (x+2)[/tex]
Step-by-step explanation:
First you can find the slope of the line that would pass through those two points using the formula:
m = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
m = [tex]\frac{3-(-2)}{8-4}[/tex]
m=5/4
Now you can just plug the slope and one of the points into point-slope form for an equation of the line that will pass through both points. You can choose either point here: I'll just use the first one.
So,
[tex]y-4=\frac{5}{4} (x+2)[/tex]

What is the 21st term of the sequence with a1 = -6 and d = 4?
choices-
74
70
78
-40
Answer:
[tex]\boxed {\boxed {\sf 74}}[/tex]
Step-by-step explanation:
The nth term of an arithmetic sequence can be found using the following formula.
[tex]a_n=a_1+(n-1)d[/tex]
Where n is the term, a₁ is the first term, and d is the common difference.
We want to find the 21st term, we know the first term is -6, and the common difference is 4.
[tex]n= 21\\a_1= -6 \\d=4[/tex]
Substitute the values into the formula.
[tex]a_{21}=-6+(21-1)4[/tex]
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Solve inside the parentheses.
[tex]a_{21}=-6+(20)4[/tex]
Multiply 20 and 4.
[tex]a_{21}= -6+80 \\[/tex]
Add -6 and 80.
[tex]a_{21}=74[/tex]
The 21st term of the sequence is 74
Answer:
SoluTion :-Here we will use the formula
[tex] \tt \: a_n \: = a_1 +( n - 1)\: \times d[/tex]
[tex] \tt\: a_{21} = −6+(21−1)4[/tex]
By using PEMDAS
[tex] \tt \: a_{21} = - 6 + (20)4[/tex]
[tex] \tt \: a_{21} \: = - 6 + 80 = 74[/tex]

A manager is going to purchase new processing equipment and must decide on the number of spare parts to order with the new equipment. The spares cost $179 each, and any unused spares will have an expected salvage value of $49 each. The probability of usage can be described by this distribution: Number 0 1 2 3 Probability .05 .60 .20 .15 Click here for the Excel Data File If a part fails and a spare is not available, 2 days will be needed to obtain a replacement and install it. The cost for idle equipment is $640 per day. What quantity of spares should be ordered
Answer:
service level is 90.78% ( it falls on cumulative probability of 1.00 or 100%)
Therefore the quantity of spares that should be ordered is 3
Step-by-step explanation:
Given that;
spares cost = $179 each
salvage value = $49 each
distribution of the probability of usage;
Number Probability cumulative Probability
0 0.05 0.05
1 0.60 0.65
2 0.20 0.85
3 0.15 1.00
Now
the cost of stock-out (underestimation) Cu
= $640 per day × 2 days = $1,280
the cost of excess inventory (overestimation) Co
= Unit cost - salvage value = $179 - $49 = $130
Therefore Service Level = Cu / ( Cu + Co )
we substitute
Service Level = $1,280 / ( $1,280 + $130 )
= $1,280 / $1410
= 0.9078 or 90.78%
so service level is 90.78% ( it falls on cumulative probability of 1.00 0r 100%)
Therefore the quantity of spares that should be ordered is 3
Read this E[2X^2 â€" Y].
I know part of it is read as the expected value of two times x square but what do these symbol mean â€" Y.
Write it down in English letters not mathematical expression
Thanx
Looks like a badly encoded/decoded symbol. It's supposed to be a minus sign, so you're asked to find the expectation of 2X ² - Y.
If you don't know how X or Y are distributed, but you know E[X ²] and E[Y], then it's as simple as distributing the expectation over the sum:
E[2X ² - Y] = 2 E[X ²] - E[Y]
Or, if you're given the expectation and variance of X, you have
Var[X] = E[X ²] - E[X]²
→ E[2X ² - Y] = 2 (Var[X] + E[X]²) - E[Y]
Otherwise, you may be given the density function, or joint density, in which case you can determine the expectations by computing an integral or sum.

5
Answer:
5
Step-by-step explanation:
if your subtracting a negative number, you just add it.
Answer:
The answer is 5.
Step-by-step explanation:
There is a double negative in the equation, represented by -(-2). A double negative always equals a positive, so the equation will now translate to 3+2, which is 5.
marking brainiiest Emery makes $15 per hour in addition to 2.25% commission on her sales each week. If her sales were $3,200 last week, how much will Emery be paid if she worked 38 hours?
Answer:
Step-by-step explanation:
Emery is paid 15 dollars an hour and she worked 38 hours
15*38=570 dollars just from the hourly wage
the commission is 2.25% and her sales were 3,200 dollars
(3200*2.25)/100=72
total=570+72=642

A line passes through (-2, 10) and (8.-9). Write an equation for the line in point-slope
form AND rewrite the equation in standard form using integers.
Merry Christmas and Happy Holidays!!! <3
Answer:
The Standard Form of the equation of a line is: Ax+By=C
Converting that, once and forevermore, into slope-intercept form, and remembering the result,
the slope m=(-A/B).
If the given slope is 8, the equation of the line is 8x-y=C and we a point to determine C. Use (2,10)
8(2)-10=C
6 = C
The equation of the line, in Standard Form, is: 8x - y = 6
