Answer: D. The distance from A to C
Step-by-step explanation:
This formula can be used to find the distance between two points on a three-dimensional coordinate system:
D(x, y, z) = \(\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2} + (z_{2} - z_{1})^{2} }\)
If you apply the formula for all options, you will find the distance from A to C is equal to \(\sqrt{5}\). The other distances are:
A. \(\sqrt{17}\)
B. \(\sqrt{45}\)
C. \(\sqrt{44}\)
So, the answer is D.
S vi) The temperature in Gulmerg in Kashmir was-10°C in January and it rose by 44°c to reach the maximum temperature during summer. The maximum temperature during summer in that year was
The maximum temperature during summer in that year was 34°C.
It's not possible for the maximum temperature in Gulmarg, Kashmir to rise by 44°C during the summer.
A temperature rise of that magnitude would be extremely unusual and potentially dangerous.
However, assuming that the question meant to ask about the difference between the minimum temperature in January and the maximum temperature in summer, we can proceed with the calculation.
The minimum temperature in January was -10°C, and if we add 44°C to it, we get:
-10°C + 44°C = 34°C
Therefore, the maximum temperature during summer in that year was 34°C.

Aurora is planning to participate in an event at her school's field day that requires her to complete tasks at various stations in the fastest time possible. To prepare for the event, she is practicing and keeping track of her time to complete each station. The x-coordinate is the station number, and the y-coordinate is the time in minutes since the start of the race that she completed the task. (1, 2), (2, 4), (3, 8), (4, 16) Part A: Is this data modeling a linear function or an exponential function? Explain your answer. (2 points) Part B: Write a function to represent the data. Show your work. (4 points) Part C: Determine the average rate of change between station 2 and station 4. Show your work. (4 points)
Answer:
Part A:
This data is modeling an exponential function because the y-values are increasing at an increasing rate. For example, between station 1 and station 2, the time increased by 2 minutes, and between station 2 and station 3, the time increased by 4 minutes. The time between each station is increasing by a multiple of the time between the previous two stations. This indicates that the data follows an exponential curve.
Part B:
To represent this data as a function, we can use the formula y = ab^x, where a and b are constants and x is the input (station number).
Substituting in the values from the first data point, we get: 2 = ab^1
Substituting in the values from the second data point, we get: 4 = ab^2
We can then solve for a and b by dividing these equations:
4/2 = (ab^2)/(ab^1)
2 = b
Substituting this value back into the first equation, we get:
2 = a*2^1
1 = a
Therefore, the function that represents this data is y = 2^x.
Part C:
To find the average rate of change between station 2 and station 4, we can use the formula: (y2 - y1)/(x2 - x1).
Substituting in the values from the data, we get: (16 - 4)/(4 - 2) = 12/2 = 6.
Therefore, the average rate of change between station 2 and station 4 is 6.

Write the inequality in interval notation and graph.
The inequality in interval notation is [ -1, ∞ ) from the given equation x ≥ - 3
What is interval notation ?Continuous sets of real numbers can be represented using interval notation by the numbers that bound them. When written, intervals resemble ordered pairs in several ways. They do not, however, intend to indicate any particular location. Instead, they serve as a concise approach to express an inequality or a set of inequalities.A set of real numbers known as an interval in mathematics contains all real numbers falling inside any two of the set's numbers. For instance, the interval containing 0, 1, and all integers in between is the set of values x satisfying 0 x 1.a collection of all real numbers. The interval notation (,) can be used to denote a function's domain as only real values.Given data :
x ≥ - 3
x is greater than or equal to - 3, so - 3 is our smallest value of the interval so it goes on the left. Since there is no upper endpoint (it is ALL values greater than or equal to 3),
we put the infinity symbol on the right side. The boxed end on 3 indicates a closed interval.

After working satisfactorily for 6 months, Collin will be eligible for a 7% raise. How much will Collin's
gross salary be, after her raise, for each 2-week pay period? His current gross salary is $1,083.34.
Collin's gross salary, after the 7% raise, for each 2-week pay period, will be approximately $1,159.17.
To calculate Collin's gross salary after the 7% raise for each 2-week pay period, we need to find the raise amount and add it to his current gross salary.
Collin's current gross salary is $1,083.34.
To find the raise amount, we multiply his current gross salary by 7% (or 0.07):
Raise amount = $1,083.34 \(\times\) 0.07
= $75.8338 (rounded to two decimal places)
Now, we add the raise amount to his current gross salary to find the new gross salary:
New gross salary = $1,083.34 + $75.8338 = $1,159.1738 (rounded to two decimal places)

Are the triangles below acute,obtuse or right
Step-by-step explanation:
this is just a matter of a very simple definition :
an acute triangle has only angles that are smaller than 90°.
an obtuse triangle has one angle that is larger than 90°.
a right or right-angled triangle has one angle with exactly 90°.
keep in mind, the sum of all angles in a triangle is always 180°.
so, there cannot be 2 angles with 90° or more than 90°.
therefore,
A : acute
B : obtuse
C and D : right

Answer:
\((a)\ G(t) = 100 *e^{0.1823t}\)
\((b)\ t = 6\)
\((c)\ t = 1.7\)
Step-by-step explanation:
Given
\(G_0 = 100\) --- initial
\(G(1) = 120\) --- after 1 year
\(r \to rate\)
Solving (a): The expression for g
Since the rate is constant, the distribution of G follows:
\(G(t) = G_0 * e^{rt}\)
\(G(1) = 120\) implies that:
\(G(t) = G_0 * e^{rt}\)
\(120 = G_0 * e^{r*1}\)
Substitute \(G_0 = 100\)
\(120 = 100 * e^{r\)
Divide both sides by 100
\(1.2 = e^{r\)
Take natural logarithm of both sides
\(\ln(1.2) = \ln(e^r)\)
\(0.1823 = r\)
\(r = 0.1823\)
So, the expression for G is:
\(G(t) = G_0 * e^{rt}\)
\(G(t) = 100 *e^{0.1823t}\)
Solving (b): t when G(t) = 300
We have:
\(G(t) = 100 *e^{0.1823t}\)
\(300 = 100 *e^{0.1823t}\)
Divide both sides by 100
\(3 = e^{0.1823t}\)
Take natural logarithm
\(\ln(3) = \ln(e^{0.1823t})\)
\(1.099 = 0.1823t\)
Solve for t
\(t = \frac{1.099}{0.1823}\)
\(t = 6\) --- approximated
Solving (c): When there will be no grass
Reduction at a rate of 80 tons per year implies that:
\(G(t) = 100 *e^{0.1823t}- 80t\)
To solve for t, we set G(t) = 0
\(0 = 100 *e^{0.1823t}- 80t\\\)
Rewrite as
\(80t = 100 *e^{0.1823t}\)
Divide both sides by 100
\(0.8t = e^{0.1823t}\)
Take natural logarithm of both sides
\(\ln( 0.8t) = \ln(e^{0.1823t})\)
\(\ln( 0.8t) = 0.1823t\)
Plot the graph of: \(\ln( 0.8t) = 0.1823t\)
\(t = 1.7\)

Sera had the number 548.She adds one to the tens and two to the units. What number would Sera end up with??
The number she'd have is:
560Explanation:
First, let's see which number is in the tens place and which number is in the ones place (the units place).
In the number 548, the place value of 5 is hundreds, the place value of 4 is tens, and the place value of 8 is ones (or units).
So if Sera adds two to the units, she'll have 10. But, since we can't write the number as 5410 (that would be a totally different number), we just write 0 in the units place, and shift 1 to the tens place, which gives us :
550
That's not all, since we also add 1 to the tens:
560
Hence, Sera ends up with 560.Statins are used to keep cholesterol in check and are a top-selling drug in the

What is the probability that both events will occur? Two dice are tossed. Event A: the first die is a 5 or 6. Event B: The second die is not a 1
Answer: The probability that both events A and B will occur is 5/18 or 0.28.
Step-by-step explanation:
To determine the probability that both events A and B will occur, we need to calculate the probabilities of each event separately and then multiply them together.
Event A: The probability of rolling a 5 or 6 on the first die is 2 out of 6 (since there are two favorable outcomes out of six possible outcomes on a fair six-sided die). Therefore, the probability of event A is 2/6 or 1/3.
Event B: The probability of not rolling a 1 on the second die is 5 out of 6 (since there are five favorable outcomes out of six possible outcomes). Therefore, the probability of event B is 5/6.
To find the probability that both events A and B occur, we multiply the probabilities:
Probability(A and B) = Probability(A) * Probability(B) = (1/3) * (5/6) = 5/18.
