Step-by-step explanation:
First, you would combine like terms, 9* and 32* then you would time by 2.
At the top of the mountain, you and your friend tart decending at the ame time. There i an angle of 18o between the two of you. You are travelling fater and therefore cover 250 m, while your friend only cover 195 m. How far apart are you at that point in time?
You and your friend are approximately 181.23 meters apart at that point in time.
Distance Between Friends On MountainTo find the distance between you and your friend, we can use the Pythagorean theorem. Let's call the distance between you two "d".
d² = 250² + 195² - 2 X 250 X 195 X cos(18)
d = √(250² + 195² - 2 X 250 × 195 X cos(18))
d ≈ 181.23 m
So you and your friend are approximately 181.23 meters apart.
The answer was determined using the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two smaller sides equals the square of the length of the largest side (the hypotenuse).
In this case, the two smaller sides represent the distances covered by you and your friend, and the hypotenuse represents the distance between you both.
We can use the theorem to calculate the distance "d" between you and your friend by rearranging the equation to isolate "d". We know the lengths of the two smaller sides (250 m and 195 m), and we also know the angle between them (18 degrees).
We can use the cosine formula to find the cosine of 18 degrees, and plug in all the values into the equation to find "d".

Round answer to the nearest hundredth
Using the cosine ratio, the measure of angle A, to the nearest hundredth is: 75.52°.
What is the Cosine Ratio?The cosine ratio, also known simply as the cosine, is a trigonometric function that represents the ratio of the adjacent side to the hypotenuse of a right triangle.
It is defined as cos(θ) = adjacent side/hypotenuse, where θ is the angle between the adjacent side and the hypotenuse.
Reference angle (∅) = A
Length of adjacent side = 2
Length of hypotenuse = 8
Therefore:
cos A = adj./hyp. = 2/8
cos A = 1/4
A = cos^(-1)(1/4)
A = 75.52°

The volume of a gas was measured as
its temperature was increased from 10 K
to 15 K at intervals of 1 K. The volumes
were 1. 5, 2. 2, 3. 38, 5. 1, and 7. 6 cm.
Would a linear or exponential function
better approximate the data described?
Explain why.
An exponential function would better approximate the data described about the volume of a gas.
The relationship between the volume of a gas and its temperature is described by the Ideal Gas Law, which states that the volume of a gas is proportional to its temperature raised to the power of the ratio of specific heat to the universal gas constant. Therefore, as the temperature of a gas increases, its volume will increase exponentially.
The data given in the problem, with the volume increasing as the temperature increases, supports the use of an exponential function to model the relationship between temperature and volume. On the other hand, a linear function, which models a constant rate of change, would not accurately capture the exponential increase in volume as the temperature increases.

what is the time complexity of this pseudocode? for int i = 1; i<=n; i )
The size of the input is doubled, the time taken to execute the loop will also double.
The time complexity of this pseudocode is O(n). This can be determined by analyzing the number of times the loop is executed. The loop is entered once and is then executed n times, where n is the number of times the loop is executed. This can be expressed mathematically as T(n) = 1 + n. Since the loop is executed a constant number of times, regardless of the size of the input, the time complexity of the pseudocode is O(n). This means that the execution time of the loop grows linearly with the size of the input. Thus, if the size of the input is doubled, the time taken to execute the loop will also double.

b. What is the probability of rolling an even number or a 4?
the probability of rolling an odd number or rolling a 2 is 2/3
The probability of rolling an even number or a 4 is 2/3
How to find the probability of rolling an odd number or rolling a 2?Probability is a mathematical concept that measures the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 means an event is impossible and 1 means an event is certain to occur. The probability of an event can also be expressed as a percentage or as a fraction.
If you roll a six-sided die. The probability of rolling 1, 2, 3, 4, 5 and 6 are as follows:
P (1) = 1/6
P (2) = 1/6
P (3) = 1/6
P (4) = 1/6
P (5) = 1/6
P (6) = 1/6
a. Since there are three odd numbers, P(odd) = 3/6 = 1/2
Thus, the probability of rolling an odd number or rolling a 2 will be:
P(odd or 2) = P(odd) + P(2)
= 1/2 + 1/6 = 2/3
b. Since there are three even numbers, P(even) = 3/6 = 1/2

B. 0.0637
C. 0.0588
D. 0.0250
The probability of selecting a spade and then selecting a heart is 0.0625, and the correct answer is option A.
What is probability?Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.
Given that the cards are selected with replacement.
The probability of selecting a spade card is:
P(S) =13/52
Now, a heart card is selected.
Since, the previous card is replaced in the deck the total number of cards is 52.
The probability of selecting a heart card is:
P(H) = 13/ 52
The probability of selecting a spade and then selecting a heart is:
P = 13 / 52 × 13/52
P = 0.0625
Hence, the probability of selecting a spade and then selecting a heart is 0.0625, and the correct answer is option A.
