How do you solve an equation with x and y in one?
There are infinitely many solutions to an equation with two variables.
We know that an equation is a mathematical statement that contains equal symbol between two mathematical expressions.
In this question need to solve an equation with x and y in one equation.
Consider an equation with two variables: 5x + y = 8
If we solve given equation for x then it would be,
5x + y = 8
5x + y - y = 8 - y
5x/5 = (8 - y)/5
x = (8 - y)/5
for any arbitrary real value value of y we can find the value of x.
This means there are infinitely many solutions.
If we solve given equation for y then it would be,
5x + y = 8
5x + y - 5x = 8 - 5x
y = 8 - 5x
for any arbitrary real value value of x we can find the value of y.
Therefore, an equation with two variables has infinitely many solutions.

d. 41 ∘
e. 90 ∘
The approximate noon Sun angle at 41°N latitude (on Long Island) on February 14th is 61°. None of the provided answer choices match the correct answer.
To calculate the approximate noon Sun angle at 41°N latitude (on Long Island) on February 14th, we can use the analemma.
The analemma is a figure-8 shaped curve that represents the position of the Sun in the sky at the same time each day over the course of a year. It accounts for the Earth's axial tilt and elliptical orbit around the Sun.
To find the approximate noon Sun angle, we need to consider the declination of the Sun on February 14th and the latitude of Long Island.
On February 14th, the Sun's declination is approximately -12°.
The Sun angle at noon can be calculated using the following formula:
Sun angle = 90° - (latitude - declination)
Substituting the values, we have:
Sun angle = 90° - (41° - (-12°))
Simplifying this equation, we get:
Sun angle = 90° - 41° + 12°
Sun angle = 61°
Therefore, the approximate noon Sun angle at 41°N latitude (on Long Island) on February 14th is 61°.

Answer: TrueExplanation:
Since \(WV+VU \ne 12\),
we can set up this equation
WV + VU = 12 + k
where k is nonzero
If k = 0 happened, then we'd land on WV+VU = 12. So we want anything but k = 0.
Let's plug in VU = 5 and see what happens
WV + VU = 12 + k
WV + 5 = 12+k
WV = 12+k-5
WV = 7+k
This shows the connection of \(WV+VU \ne 12 \text{ and } VU = 5\) leading to \(WV \ne 7\)

Angle A = 100 degrees, which leaves 180-A=180-100 = 80 degrees to be split amongst the two remaining angles of triangle ABC.
This leftover amount (80) is not larger than 90. So there is no way to have angle B = 90
It turns out that any obtuse triangle cannot have a 90 degree angle. The other two angles must be acute.

usage patterns are a variable used in blank______ segmentation.
Answer:
usage patterns are a variable used in market segmentation.
Step-by-step explanation:
Usage patterns are a variable used in behavioral segmentation.
Behavioral segmentation is a marketing strategy that divides a market into different segments based on consumer behavior, specifically their patterns of product usage, buying habits, and decision-making processes. This segmentation approach recognizes that customers with similar behavioral characteristics are likely to exhibit similar preferences and respond in a similar manner to marketing initiatives.
Usage patterns, as a variable, help marketers understand and classify customers based on how they interact with a product or service. This can include factors such as the frequency of product usage, the amount of product used, the timing of purchases, brand loyalty, product benefits sought, and other behavioral indicators.
By analyzing usage patterns, marketers can identify distinct segments within their target market and tailor marketing strategies to meet the unique needs and preferences of each segment. This enables companies to develop more targeted marketing campaigns, optimize product offerings, improve customer satisfaction, and drive customer loyalty.
Overall, behavioral segmentation, including the consideration of usage patterns, allows companies to better understand and connect with their customers by aligning their marketing efforts with specific behaviors and motivations.

At this point, what is her elevation, in feet?
Answer:
d = 102 below the surface of the sea.
Step-by-step explanation:
65 Seconds -- Direction down
d = ?
r = 4.9 feet / second
t = 65
d = 4.9 * 65 = 318 feet below sea level.
60 seconds -- direction up
t = 60 seconds
r = 2.1 feet/second
d = 2.1 *60 = 126 upwards.

In triangle ABC, let I be the incenter and Γ be the circumcircle. Extend AI to intersect the circle at L.
Show that L is the circumcenter of triangle BIC
To prove that L is the circumcenter of triangle BIC, we need to show that LI is perpendicular to BC.
What is it about?Firstly, let M be the midpoint of BC. By the definition of the incenter, we know that BI = CI. Now, since L is on the circumcircle, we have ∠ALC = 2∠ABC. But ∠ALI = 90 + 1/2∠BAC = 90 + 1/2(∠ABC + ∠ACB) = 90 + 1/2∠ABC + 1/2∠BIC.
Using these angles, we can see that ∠ILC = ∠ALC - ∠ALI = 2∠ABC - (90 + 1/2∠ABC + 1/2∠BIC) = 1/2(∠ABC - ∠BIC) and ∠ILB = ∠IBC - ∠ALB = 1/2(∠ABC - ∠BIC).
Therefore, ∠ILC = ∠ILB, and since MI bisects ∠BIC, we have ML = MI = MC, which implies that LI is perpendicular to BC and L is the circumcenter of triangle BIC.
Therefore, MI is perpendicular to BC and also bisects angle BIC.
