Both of the triangles are RIGHT triangles. y X(0,13) Y(0,7) Z(0,3) (0,0) J. the length of vertical segment XY is 6.
What is a vertical segment?Generally, A part of a line that is totally vertical is referred to as a vertical line segment. This means that the two vertices that make up the segment's ends have the same x- and y-coordinates but different z-coordinates than one another.
The length of vertical segment XY can be found by subtracting the y-coordinate of point X from the y-coordinate of point Y.
In this case, the y-coordinate of point X is 13 and the y-coordinate of point Y is 7, so the length of vertical segment XY is
13 - 7 = 6.

the work to prove that the series is convergent using one of the convergence series tests.the series a is convergent and series b is divergent.
a. The alternating series test can be used to prove that the series is convergent. The alternating series test states that if a series is of the form [tex]$a_1-a_2+a_3-a_4+\cdots$[/tex] and satisfies the conditions:
1. [tex]$a_n \geq 0$[/tex] for all n
2. [tex]$a_{n+1} \leq a_n$[/tex] for all n
3. [tex]$\lim_{n\to \infty} a_n = 0$[/tex]
Then the series is convergent.
In this case, the series is of the form [tex]$2-\frac{2}{2}+\frac{2}{3}-\frac{2}{4}+\cdots$[/tex] which satisfies all the conditions of the alternating series test.
Therefore, the series is convergent.
b. The divergence test states that if the limit of the sequence of partial sums is not finite, then the series is divergent. However, in this case, the limit of the sequence of partial sums is finite and thus the divergence test fails to prove that the series is divergent.

Pls help with this I put in a photo
Step-by-step explanation:
to be a triangle the sum of any 2 sides must be larger than the third side.
so,
x + 10 > 18
x + 18 > 10
18 + 10 > x
the first inequality gives us
x > 8
the third inequality gives us
28 > x
the second inequality would give us
x > -8
but with the first inequality x > 8 we have already a stronger criteria than x > -8 (if x > 8 is true, then so is automatically x > -8, but not the other way around).
therefore x > 8 is the narrower criteria and answer.
so, we have in combination
8 < x < 28
Eliminate the y in the following system of equations. What is the result when you add the two equations?
x+y=2
3x-4y=27
Answer:
thus: x = 5, y = -3
Step-by-step explanation:
Solve the following system:
{y + x = 2 | (equation 1)
-4 y + 3 x = 27 | (equation 2)
Swap equation 1 with equation 2:
{3 x - 4 y = 27 | (equation 1)
x + y = 2 | (equation 2)
Subtract 1/3 × (equation 1) from equation 2:
{3 x - 4 y = 27 | (equation 1)
0 x + (7 y)/3 = -7 | (equation 2)
Multiply equation 2 by 3/7:
{3 x - 4 y = 27 | (equation 1)
0 x + y = -3 | (equation 2)
Add 4 × (equation 2) to equation 1:
{3 x + 0 y = 15 | (equation 1)
0 x + y = -3 | (equation 2)
Divide equation 1 by 3:
{x + 0 y = 5 | (equation 1)
0 x + y = -3 | (equation 2)
Collect results:
Answer: {x = 5, y = -3

Answer:
Step-by-step explanation:
To plot the positive rational numbers on the number line, you can use the following steps:Start by drawing a number line, with 0 at the left end and positive numbers increasing as you move to the right.Place the first number, 12, on the number line. You can place it to the right of 0, since it is a positive number.Place the next number, 134.16, to the right of 12. You can place it farther to the right, since it is a larger number.Place the next number, 310/8, to the right of 134.16. Since 310/8 is equal to 38.75, you can place it slightly to the right of 134.16, but still to the left of 39.Place the next number, 0, at the left end of the number line, since it is equal to 0.Place the next number, 1, to the right of 0, since it is a positive number.Place the next number, -2.05, to the left of 0, since it is a negative number.Place the final two numbers, 2 and 3, to the right of 1, since they are both positive numbers.The resulting number line should look something like this:-2.05 0 1 2 3 12 134.16 38.75 (310/8)
Paul drives his delivery van 675 miles in 3 days. at this rate, how far will he drive in 15 days?
a. 45 miles
b. 225 miles
c. 2,025 miles
d. 3,375 miles
Therefore, the correct answer is 3,375 miles, or option (d) is the correct option.
To find out how far Paul will drive in 15 days, we need to determine his average distance per day and then multiply that number by 15. To find Paul's average distance per day, we can divide the total distance he drove in 3 days by the number of days:
675 miles / 3 days = 225 miles/day.
So Paul drives an average of 225 miles per day. If he continues to drive this same distance every day, he will drive 225 miles/day * 15 days = <<225*15=3375>>3,375 miles in 15 days.
Why does it have the name "average speed"?The total distance something has traveled is divided by the total amount of time it took to traverse that distance to arrive at its average speed. Speed is the current rate of movement of something. Average speed is the speed that a vehicle travels at on average over the course of a trip.
What does the term "average speed" mean?A moving object's average speed is calculated by dividing its total distance traveled by its entire travel time. Distance traveled divided by average speed Overall Time. Meter per second is the S.I. unit of speed. KPH, or kilometers per hour, is another unit of speed.

x = 11midline = 16baseline = 32Step-by-step explanation:
You have a triangle with its midline length given as x+5 and its parallel base line length given as 3x-1. We presume you want to know the value of x and the lengths of the segments.
MidlineThe midline is half the length of the parallel base line, so you have ...
x +5 = 1/2(3x -1)
Solution2x +10 = 3x -1 . . . . . . . multiply by 2
11 = x . . . . . . . . . . . . . add 1-2x
The midline length is x+5 = 11+5 = 16.
The base line length is 3x-1 = 33 -1 = 32, twice the length of the midline.
The solution to the triangle is ...
x = 11midline = 16base line = 32Find the value of this variable
A. 146 degree
B. 73 degree
C. 84 degree
D. 62 degree

Answer: B. 73 degree
Step-by-step explanation:
We know that a triangle has 180 degree
62 + 84 = 146 degree
180 - 146 = 34 degree
34 degrees is the angle inside the triangle. The inside angle must add with the outside angle = 180 degree
So the outside angle is

if the coefficient of determination is a positive value, then the regression equation
Answer:
close to 1, good fit
Step-by-step explanation:
If the coefficient of determination is a positive value, it means that the regression equation is a good fit for the data. The coefficient of determination, denoted by r^2, is a measure of how well the regression equation explains the variation in the data. A value of r^2 close to 1 indicates that the regression equation explains a large portion of the variation in the data, while a value of r^2 close to 0 indicates that the regression equation does not explain much of the variation in the data.
Therefore, if the coefficient of determination is a positive value, it means that the regression equation is a good fit for the data and explains a significant portion of the variation in the data. This means that the regression equation is likely to be a reliable model for the data and can be used to make predictions about the values of the dependent variable based on the values of the independent variable.
As a pharmacist, you are responsible for knowing about medication dosage, and how long a dose stays in the patient's system. Let's look at an example of a common medication, called ibuprofen. When a patient takes a 400 mg dose of ibuprofen, it releases into the bloodstream at a certain rate, and then decreases over time. The function that models this concentration of medicine over time is complex and looks like this:
P(t) = 0.5t + 3.45t³ - 96.65t² + 347.7t, when 0 ≤t≤6 . In this function above, P(t) is the amount of medication (in mg) in the
blood stream at time t (in hours).

◦ This year, a herd of bison had a 10% increase in population. If there were 550 bison in the herd last year, how many are in the herd this year?
◦ This year, another herd of bison had a 10% decrease in population. If there are 550 bison in the herd this year, how many bison were there last year?
Answer: No, it works out to a different number. The 1st will end up with 605 bison.
Step-by-step explanation:
1st Herd: (550 x 10%) = 55 Bison
550 + 55 = 605 Thus 550 with a 10% increase is 605 Bison.
2nd herd: if you take 10% of 605 bison that number of (60.5) will give you a greater loss when taken away from 605.
605 - 60.5 = 544.5 bison remaining if 605 has a 10% loss.
Herd 2 started with approximately 611 bison. Check your math by multiplying 611 by 10% = 61.1
then subtract (611 - 61.1) = 549.9
So Herd 1 Does Not Equal Herd 2.
Find the volume of the largest right circular cone that can fit in a cube whose

The largest right circular cone that can fit within a cube has a volume of 718.67 cm3.
Explain about the circular cone?When a cone's axis is the line from the vertex to the circular base's midpoint, the cone is said to be right circular. In other words, a right angle is formed when the center of the circular base joins the cone's peak.
A three-dimensional form called an inverted frustum that resembles a conical cylinder. When the vertex of a cone is inverted after being sliced by a plane parallel to the shape's base, it is said to have this shape.
The formula r2+rl, where r is the radius of the circular base, h is the height of the cone, l is the slant height, and is an approximation, is used to determine the surface area of a cone as 3.14

Winton bought - 2 kg of strawberry taffy and 1 kg of banana taffy for $20.
Audrey bought - 4 kg of strawberry taffy and 4 kg of banana taffy for $52.
Then, we can write the above information into equations as
2S + B = 20 ...(1)
4S + 4B = 52 ...(2)
Where S represents strawberry taffy and B represents banana taffy.
From (1), we can write
B = 20 - 2S
Then, on substituting in (2), we get
4S + 4(20 - 2S) = 52
