Answer: y= -1/20x + 38/5
or
y= -1/20x + 7.6
Step-by-step explanation:
y-y1 = m(x-x1)
m = 8-7 / -8 - 12 = 1/-20 = -1/20
y-8 = -1/20(x+8)
y=-1/20x - 8/20 + 160/20
y= -1/20x + 38/5
or
y= -1/20x + 7.6

As per the question,
Y = prize money$100,000 is the money you get30% is deducted from YSolving for Y
Convert 30% to decimal formDivide 30% by 100%30%/100% = 0.3Now, solve the equation.100,000 = Y - 0.3Y100,000 = 0.7Y100,000 = 7Y/10Y = 1,000,000/7Y = $142,857.14Δ ABC and ΔDEF are similar triangles. If m∠A =104∘and m∠E = 36∘, what is ∠C?
1. 36
2. 40
3. 76
4. 104
Answer:
2
x=40
Step-by-step explanation:
A triangle has 180 degrees and considering that triangle ABC is similar to DEF that means they have the same angle (A=D,B=E,C=F)
180=104 +36+x
180=140+x
180-140=x

please help! what is the arc RU? thank you so much!
Answer: 92° or 1.6057 radians
Step-by-step explanation:
the 4 angles created by the intersecting lines SU and RT have to equal 360°
<v = 88° because of vertical angles so
88° • 2 = 176°
360° - 176° = 184°
184°/ 2 = 92°
92°+92°+88°+88° = 360°
then, that makes 92° the central angle of arc RU and the central angle degrees is always equal to the arc it subtends

A locker requires a three-digit code to open the lock. The code must contain one letter and two numbers, and no letter or number can be repeated. You can choose from among four letters, A, B, C, and D, and two numbers, 5 and 6.

If a code is chosen at random, the probability that D is in the code but is not in the first position is
Answer:
B56 or D65 or B65 or D56
Step-by-step explanation:
a. 36, 26letters + 10 numbers
b. 1/2
c. 1/4
The size of the sample space is 8.
The probability that it has a letter that immediately follows an odd number is 1/2.
There is no probability that D is in the code but not in the first position.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
The size of the sample space is the number of ways to choose one letter and two numbers, without repetition.
We can choose the letter in 4 ways, the first number in 2 ways, and the second number in 1 way (since we can't repeat a number), giving a total of 4 x 2 x 1 = 8 possible codes.
Let's list all the possible codes: 5A6, 5B6, 5C6, 5D6, 56A, 56B, 56C, 56D
The probability that a code has a letter that immediately follows an odd number:
We need to count the number of codes that have a letter following an odd number.
From the list above, we see that the codes 5B6, 5D6, 56B, and 56D have a letter following an odd number.
Therefore, there are four favorable outcomes out of eight possible outcomes.
So the probability is 4/8 = 1/2.
The Probability that D is in the code but not in the first position:
D can be in the second or third position.
If D is in the second position, there are 3 ways to choose the first digit (since we can't use D, and we can't repeat the first digit), and 1 way to choose the third digit, giving a total of 3 * 1 = 3 codes.
If D is in the third position, there are 3 ways to choose the first digit and 2 ways to choose the second digit (since we can't repeat any digit), giving a total of 3 x 2 = 6 codes.
So there are 3 + 6 = 9 favorable outcomes out of 8 possible outcomes (since there are 8 possible codes in total).
Therefore, the probability is 9/8, which is greater than 1.
This is not possible, so the answer is that there is no probability that D is in the code but not in the first position.
Thus,
The size of the sample space is 8.
The probability that it has a letter that immediately follows an odd number is 1/2.
There is no probability that D is in the code but not in the first position.

Step 2: Find Limit
Let's start out by directly substituting x = 0 into our limit.
[Limit] Apply Limit Rule [Variable Direct Substitution]:We can see that the cotangent of 0 is undefined. Since we do not have an indeterminate form, we cannot use L'Hopital's Rule. Let's look at the function graphically (refer to the attachment).
Approaching the left limit, we can see that the graph heads towards negative infinity.
Approaching the right limit, we can see that the graph also heads towards negative infinity.
∴ we can say that the limit as x approaches 0 is equal to negative infinity.
