The area of the triangle in the given diagram is
[tex]1/2\sqrt{(x^2_1 + y^2_1)(x^2_2 + y^2_2)}[/tex]
Option A is the correct answer.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
The area of a triangle is given by the formula:
Area = (1/2) x base x height
In this case,
The base of the triangle is the distance between points A and C, which is given by the distance formula:
base = √((x1 - 0)² + (y1 - 0)²)
Similarly, the height of the triangle is the distance between points A and B, which is given by:
height = √((x2 - 0)² + (y2 - 0)²)
Therefore,
The area of the triangle is:
Area = (1/2) x √((x1 - 0)² + (y1 - 0)²) x √((x2 - 0)² + (y2 - 0)²)
Simplifying further:
Area =
[tex]1/2\sqrt{(x^2_1 + y^2_1)} \sqrt{(x^2_2 + y^2_2)}[/tex]
Thus,
The area of the triangle in the given diagram is
[tex]1/2\sqrt{(x^2_1 + y^2_1)(x^2_2 + y^2_2)}[/tex]

Can you please help me with #13?I don't know how to find the answer.
Part A
Select any two columns from the table to compute the slope
I'll pick the first two columns to select (2,246) and (4,450)
m = (y2-y1)/(x2-x1)
m = (450-246)/(4-2)
m = 102
The slope is 102. This is the daily fee. It is the cost per day to rent the beach house. This does not include the processing fee, which is the y intercept. We'll use this m value along with one of the columns of the table to help find the value of b.
y = mx+b
246 = 102*2+b
246 = 204+b
246-204 = b
42 = b
b = 42
The processing fee is $42, which is the initial starting amount of money you must pay to get the beach house (even if it turns out you never use it for a single day). Then you'll pay $102 per day on top of that $42.
Because m = 102 and b = 42 are the slope and y intercept, we go from y = mx+b to y = 102x+42
The variable x stands for the number of days. The variable y is the total cost in dollars.
Answer: y = 102x+42==============================================================
Part B
Refer to part A for the steps and explanation.
Processing fee = $42Daily fee = $102==============================================================
Part C
The budget is $1200. This means the total cost y cannot be larger than 1200.
Plug in y = 1200 and solve for x.
y = 102x+42
1200 = 102x+42
1200-42 = 102x
1158 = 102x
102x = 1158
x = 1158/102
x = 11.35294 which is approximate
Round down to the nearest whole number to get x = 11.
If x = 11, then,
y = 102x+42
y = 102*11+42
y = 1164
which is under the $1200 budget. However, if x = 12, then
y = 102x+42
y = 102*12+42
y = 1266
which is now over budget. Therefore, the highest x can get is x = 11.

Jonathan gets a weekly allowance of $18. He uses his allowance to buy 3 arcade tokens each
week. Each token costs $2. Jonathan also spends $3 on his movie streaming subscription
each week. He puts the rest of his allowance in his college fund.
How much money does Jonathan put in his college fund each week?
Answer:$9
Step-by-step explanation:
add the prices of the tokens
2+2+2=6
subtract the $3 from the subscription
18-3= 15
subtract $6 from the 15
15-6= 9
so he puts in $9 weekly

See attached.
the sum of two numbers is 200 and the two numbers are in a ratio of 4:6, what is the larger number.
Step-by-step explanation:
x + y = 200
x : y = 4 : 6
x + y = 200
y = 200 - x
x : y = 4 : 6
x : (200 - x) = 4 : 6
6.x = 4(200 - x)
6x = 800 - 4x
10x = 800
x = 800/10
x = 80
y = 200 - x
y = 200 - 80
y = 120
(x,y) = (80,120)

Solve the inequality. Graph the solution.
5(g+ 4) > 15
The solution is
Answer:
5(g+4)>15
5g+20>15
5g>15-20
5g>-5
g>-1
The solution to the inequality 5(g + 4) > 15 is g > -1 and graph of the inequality is given in attachment.
To solve the inequality 5(g + 4) > 15, follow these steps:
Distribute the 5 to both terms inside the parentheses:
5g + 20 > 15
Subtract 20 from both sides of the inequality:
5g > 15 - 20
5g > -5
Divide both sides of the inequality by 5 to isolate g:
g > -1
To graph the solution, you can represent it on a number line.
Plot an open circle at -1 (since it's not included in the solution) and shade the region to the right of -1 to represent all the values of g that are greater than -1.
Therefore, the solution to the inequality is g > -1.

Can anybody answer this
Answer:
Step-by-step explanation:
m = Δy/Δx
m = (-6 - 4) / (-4 - 5)
m = -10 / -9
m = 10/9
with only this information we can determine the answer is the first option as its the only one with the correct slope. Let's continue anyway.
y = (10/9)x + b
4 = (10/9)5 + b
36/9 = 50/9 + b
b = -14/9
y = (10/9)x - 14/9
The weekly demand for a product has a normal distribution with a mean of 1,000 and a standard deviation of 200. The current on-hand inventory is 750 and no deliveries will be occurring in the next week
Using the normal distribution, it is found that there is a 0.8943 = 89.43% probability of a demand above 750.
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem:
The mean is of 1000, hence [tex]\mu = 1000[/tex].The standard deviation is of 200, hence [tex]\sigma = 200[/tex]The probability of a demand above 750 is one subtracted by the p-value of Z when X = 750, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{750 - 1000}{200}[/tex]
[tex]Z = -1.25[/tex]
[tex]Z = -1.25[/tex] has a p-value of 0.1057.
1 - 0.1057 = 0.8943
0.8943 = 89.43% probability of a demand above 750.
