The measure of the longest side of ∆ABC is 6 units. ∆ABC is a right scalene triangle. ∆ABD is also a right scalene triangle and the length of side AD is 5 units.
The measure of the longest side of ∆ABC can be found using the distance formula.
We calculate the distance between points A(1, 7) and B(-2, 2), between points B(-2, 2) and C(4, 2), and between points A(1, 7) and C(4, 2).
The longest distance is the measure of the longest side.
Using the distance formula, we find that the longest side is 6 units long.
∆ABC is a right scalene triangle.
This is because the lengths of its sides are all different and it has a right angle at point C, where the x-coordinate doesn't change but the y-coordinate does.
∆ABD is also a right scalene triangle.
The length of side AD can be found using the distance formula between points A(1, 7) and D(1, 2).
The length of side AD is 5 units.
Given cosx=1213 and sinx=513 .
What is ratio for tanx ?
leave answer as a fraction in simplest form
Remember to show all of you work
By using the tangent formula, we will see that:
tan(x) = 5/12.
How to get the tangent of x?You just need to remember that we can write the tangent as:
tan(x) = sin(x)/cos(x).
In this case, we know that:
sin(x) = 5/13cos(x) = 12/13We can just replace these two in the tangent equation, we will get:
tan(x) = (5/13)/(12/13) = (5/13)*(13/12) = 5/12
tan(x) = 5/12

Jim and Gail invested a total of $3,600 in a stock, in a ratio of 5:7. The stock made $6,450 on top of the initial capital. If the payoff is done in the same ratio, how much does Gail get?
"Since the ratio is 5:7 you can think in total there was 12 equal blocks of money invested. 5 of those blocks belonged to Jim and 7 of those blocks belonged to Gail. Since they invested $3,600 and then made $6,450 in total there is $10,050. Divide that total into 12 equal blocks of $837.50 and 5 of those blocks belong to Jim. So he will get $4,187.50"
The amount that Gail will get is $5862.5.
What is Ratio?A ratio is a comparison of two quantities produced by dividing the first by the second. If a and b are two values of the same kind and with the same units, and b is not equal to zero, then the quotient a/b is known as the ratio between a and b. The colon sign is used to denote ratios (:). This means that the ratio a/b has no unit and can be expressed as a: b.
Given:
Jim and Gail invested a total of $3,600 in a stock, in a ratio of 5:7.
The stock made $6,450 on top of the initial capital.
Total they made
= 3600+ 6450
= $10, 050
The pay off Jim get
= 10, 050 x 5/12
= 4187.5
and, the pay off Gail get
= 10, 050 x 7/12

Body temperatures are normally distributed with a mean of 98.6° f and a standard deviation of 0.19° f. what temperature represents the 95th percentile?
To find the temperature that represents the 95th percentile, calculate the z-score using the given formula and substitute the values in the equation. Using a standard normal distribution table, the temperature is approximately 98.93°F.
Explanation:To find the temperature that represents the 95th percentile, we need to calculate the z-score corresponding to the 95th percentile.
The z-score can be calculated using the formula: z = (x - μ) / σ, where x is the temperature, μ is the mean, and σ is the standard deviation. In this case, μ = 98.6°F and σ = 0.19°F.
By looking up the z-score in the standard normal distribution table, we can find the corresponding temperature.
Using a standard normal distribution table, we find that the z-score for the 95th percentile is approximately 1.645. Substituting the values into the formula, we get: 1.645 = (x - 98.6) / 0.19.
Solving for x, we find x ≈ 98.6 + (1.645 * 0.19) ≈ 98.9295°F.
Therefore, the temperature that represents the 95th percentile is approximately 98.93°F.

What percent of 82.5 is 21.12
The 25.6 percentage of the number 82.5 is 21.12
Given data:
To find the percentage of 21.12 in relation to 82.5, the proportion is simplified as:
21.12 is to 82.5 as x is to 100.
This can be expressed as:
21.12/82.5 = x/100
On solving for x by cross multiplying:
21.12 * 100 = 82.5 * x
2112 = 82.5x
To isolate x, divide both sides by 82.5:
2112/82.5 = x
On simplifying:
25.6 ≈ x
Hence, 21.12 is approximately 25.6 percent of 82.5.

1. What is the sum of the polynomials?
(m + n + 3) + (m + n + 4)
2. Which expression can be used to find the difference of the polynomials?
(10m – 6) – (7m – 4)
3. Which expression can be used to find the difference of the polynomials?
(4m – 5) – (6m – 7 + 2n),
Answer:
1- The sum is: 2m + 2n + 7 = 2(m+n) + 7
2- The difference is: 3m - 2
3- The difference is: -2m - 2n + 2 = -2(m+n-1)
Explanation:
Before we begin, remember the following:
+ve * +ve = +ve
-ve * -ve = -ve
+ve * -ve = -ve
-ve * +ve = -ve
Also, remember that, we only add/subtract like terms. There are terms which have the same variable(s) raised to the same degree
Now, let's check the problems:
Problem 1:
Adding two polynomials:
(m + n + 3) + (m + n + 4)
We first start by getting rid of the brackets:
m + n + 3 + m + n + 4
Now, we add like terms:
2m + 2n + 7
As an additional step, we can take 2 as a common factor from the first two terms:
2(m+n) + 7
Problem 2:
Subtracting two polynomials:
(10m - 6) - (7m - 4)
We first start by getting rid of the brackets. Take care of the different signs while doing so:
10m - 6 - 7m + 4
Now, we add/subtract like terms:
3m - 2
Problem 3:
Subtracting two polynomials:
(4m - 5) - (6m - 7 + 2n)
We first start by getting rid of the brackets. Take care of the different signs while doing so:
4m - 5 - 6m + 7 - 2n
Now, we add/subtract like terms:
-2m - 2n + 2
As an additional step, we can take -2 as a common factor from the above expression:
-2(m+n-1)

What is the sum of the geometric series
Answer:
Hence, the sum of the geometric series is:
259
Step-by-step explanation:
We are given a geometric series as:
[tex]\sum_{i=1}^4 6^{i-1}[/tex]
i.e. we are asked to fnd the sum of first four terms of the geometric series with first term as 1
Since, the series is:
[tex]6^0+6^1+6^2+6^3[/tex]
Also, the common ratio of the series is: r=6
Since, each of the term of the series is 6 times it's preceding term.
Also we know that sum of a finite geometric series with n-terms and common ratio r is calculated by the formula:
[tex]S_n=a(\dfrac{r^n-1}{r-1})[/tex]
Here we have: a=1 and r=6 and n=4
Hence,
[tex]S_4=1(\dfrac{6^4-1}{6-1})\\\\\\S_4=\dfrac{1295}{5}\\\\\\S_4=259[/tex]
Hence, the sum of the series is:
