The missing side lengths are given as follows:
y = 6.93.x = 13.86.What are the trigonometric ratios?The three trigonometric ratios are defined as follows:
Sine of angle = length of opposite side divided by the length of the hypotenuse.Cosine of angle = length of adjacent side divided by the length of the hypotenuse.Tangent of angle = length of opposite side divided by the length of the opposite side.Considering the tangent of 30º, we can obtain the length y, as follows:
tan(30º) = y/12
y = 12 x tangent of 30 degrees
y = 6.93.
Applying the Pythagorean Theorem, we can obtain the length x, as follows:
x² = 6.93² + 12²
x = sqrt(6.93² + 12²)
x = 13.86.

If m/n ,in lowest terms, be the probability that a randomly chose positive divisor of 10^99 is an integral multiple of 10^88 than find the value of (m+n).
Answers
m and n are the two numbers that form the fraction which is the probability of a randomly chosen positive divisor of [tex]10^99[/tex] being an integral multiple of [tex]10^88[/tex].
Let the probability of a randomly chosen positive divisor of [tex]10^99[/tex]being an integral multiple of 10^88 be represented as m/n.
Since [tex]10^99[/tex]is a multiple of [tex]10^88[/tex], its positive divisors will also be multiples of [tex]10^88[/tex].
Therefore, the probability that a randomly chosen divisor of [tex]10^99[/tex]is an integral multiple of [tex]10^88[/tex] will be 1, i.e., m/n = 1.
Therefore, m+n = 1+1 = 2
Hence, the value of (m+n) is 2.
m and n are two numbers that form a fraction in lowest terms, which is the probability that a randomly chosen positive divisor of [tex]10^99[/tex] is an integral multiple of [tex]10^88[/tex]. To find the value of (m+n), we need to first determine the value of m and n. To do this, we must first calculate the total number of positive divisors of [tex]10^99[/tex]that are integral multiples of [tex]10^88[/tex]. We can then divide this number by the total number of positive divisors of [tex]10^99[/tex] to get the fraction. The numerator of this fraction is m and the denominator is n. The sum of m and n is the answer to the question. This is because the fraction gives us the probability that a randomly chosen positive divisor of [tex]10^99[/tex] is an integral multiple of [tex]10^88[/tex], and the sum of m and n is the total number of positive divisors of[tex]10^99[/tex], which is the denominator of the fraction. Therefore, the value of (m+n) is the sum of the numerator and denominator of the fraction.

Answer: 435
Step-by-step explanation:
Daniel wants to predict how far he can hike based on the time he spends on the hike. He collected some data on the time (in hours) and distance (in kilometers) of some of his previous hikes. Which of linear equations best describes the given model?
Answers
When Daniel creates the linear equation, he will notice that the relationship between time spent and distance travelled is proportional.
What exactly is a linear equation?The equation is referred to as linear when a variable's maximum power is 1. A one-degree equation is another name for it. A linear equation in one variable has the conventional form Ax + B = 0. This equation has three variables: x, A, and B. A is a coefficient. A linear equation in which there are only two variables typically takes the form Ax + By = C. In addition to the constant C, there are three other constants: the variables x and y, the coefficients A and B, and the variables.
Now,
When we create a linear equation for the distance of the hike, we will get a graph with a straight line.
A straight line's general equation is
y = mx + c
where m = is the slope of the line and
c = is the y-intercept
y = the distance covered
x = the time taken
Because distance is directly proportional to time,
more distance is covered in less time
Distance ∝ time
Hence,
Daniel will notice that the relationship between the time spent and distance covered are proportional.

A diff diver plunges from a height of 25 ft above the water surface. The distance the diver falls in t seconds is given by the function (t) - 16eft. Which equation can be solved fort to find the time (in seconds) when the diver hits the water?
Answers
Answer: The equation that can be solved for t to find the time (in seconds) when the diver hits the water is:
h(t) = 25 - 16e^(-ft) = 0
Where h(t) is the height of the diver in feet at time t, and f is a positive constant related to the speed of the fall.
To find the time when the diver hits the water, we set h(t) equal to zero and solve for t. This gives us the time when the height of the diver is equal to the water surface.
25 - 16e^(-ft) = 0
25 = 16e^(-ft)
e^(-ft) = 25/16
-ft = ln(25/16)
t = -ln(25/16)/f
Note that the negative sign in the equation for t indicates that the time is counted from the moment the diver starts falling. The constant f can be determined from the physical characteristics of the diver and the conditions of the fall, but it is not necessary to know the exact value of f to find the time when the diver hits the water.

anita can type 60 words to 75 words per minute it took her 43 minutes to type a 12 page report which could be the total number of words in the report
Answers
Anita can type between 60 and 75 words per minute and it took her 43 minutes to type a 12 page report.
The formula to calculate the total number of words in a report is: (words per minute * minutes) = total words. In this case, anita can type between 60 and 75 words per minute, so to solve for the total words in the 12 page report, we need to average her words per minute. This would be (60 + 75) / 2 = 67.5 words per minute. So, now the equation looks like this: (67.5 words per minute * 43 minutes) = 2,888.5 total words in the report.
To break the equation down further, we can say that for every minute Anita types, she is typing 67.5 words. This means that for every minute she types, she is typing 1.125 pages. In other words, for every 8 minutes she types, she is typing 9 pages. Therefore, to type 12 pages in 43 minutes, Anita is typing approximately 9.2 pages per 8 minutes.
To summarize, Anita can type between 60 and 75 words per minute and it took her 43 minutes to type a 12 page report. Using the formula (words per minute * minutes) = total words, we can calculate that the total number of words in the report is 2,888.

so 7% decline
if linearly = every year decline 7%
so back in 1990, 3 years ago, the population was
p° = 3820/(1-7%)^3 =3820/.8=4749
so from 1990
p = 4749 * (1-7%)^t
2009 is 16 years from 1993
so p = 3820 * (1-7%)^16 =1196
Answer:
A) P(t) = 3820 -70t
B) 2700
Step-by-step explanation:
You want a linear equation for the moose population that changed from 3820 in 1993 to 3540 in 1997, and you want the predicted population in 2009.
A)The slope of the linear function can be found from ...
m = (p2 -p1)/(t2 -t1)
If we let t represent years after 1993, then this is ...
m = (3540 -3820)/(4 -0) = -280/4 = -70
P(t) = 3820 -70t . . . . . . . . population is 3820 when t=0, 70 less each year
B)2009 is 16 years after 1993, so we want P(16):
P(16) = 3820 -70·16 = 3820 -1120
P(16) = 2700
The population is predicted to be 2700 in 2009.

What is the rationale for the above responses?
1) to obtain the value of x, we must equate AC and BD based on the diagonal properties of a rectangle. Note that a rectangle's diagonal divides it into two congruent right triangles.
A rectangle's diagonals are all the same length. A square is a quadrilateral whose diagonals bisect each other, intersect at right angles, and are congruent.
Thus,
Since BD = AC
2x + 19 = 5x - 2
To solve the equation 2x + 19 = 5x - 2, we need to isolate x on one side of the equation.
First, we can simplify both sides by combining like terms. Subtracting 2x from both sides gives:
19 = 3x - 2
Next, we can isolate x by adding 2 to both sides:
21 = 3x
Finally, we can solve for x by dividing both sides by 3:
x = 7
Therefore, the solution to the equation 2x + 19 = 5x - 2 is x = 7

Answers
The ratio of malts to shakes is 3:7 if 14 shakes are sold for every 6 malts.
What is meant by ratios?When the second number in the ordered pair, b, is not equal to 0, the ratio is expressed as a/b. An equation in which two ratios are made equal is known as a percentage. A ratio is a tool for comparing like-kind quantities or illustrating relationships between them. To compare similar items, we employ ratios.
Let the number of shakes be S and the number of malts be M.
Given: Number of shakes sold = 14 shakes
Number of malts sold = 6 malts
To find the ratio of malts to shakes:
The ratio of malts to shakes exists given by the expression:
M/S = Number of malts sold/Number of shakes sold
Substituting the given parameters into the formula, we have;
M/S = 6/14

The total cost function of a monopolist is (Q) = 3Q. The inverse demandfunction for
the monopolist’s products is P (Q) = 12 − Q.
A. find the profit-maximizing level of price and output
B. Find the maximum profit of the firm at an equilibrium price level
Answers
Step-by-step explanation:
A. To find the profit-maximizing level of price and output, we need to find the equilibrium point where the marginal revenue equals marginal cost.
The marginal cost of production is the derivative of the total cost function: MC = dC/dQ = 3.
The marginal revenue is the derivative of the inverse demand function: MR = dP/dQ = -1.
So at the profit-maximizing level of output, MC = MR.
3 = -1
Q = 6
Then we can substitute Q = 6 back into the inverse demand function to find the price:
P (Q) = 12 - Q
P (6) = 12 - 6
P = 6
So the profit-maximizing level of output is 6 units at a price of $6.
B. To find the maximum profit of the firm, we need to calculate the total revenue and the total cost at the profit-maximizing level of output.
The total revenue is the product of the price and the quantity:
TR = P * Q
TR = 6 * 6
TR = 36
The total cost is given by the total cost function:
TC = C (Q)
TC = 3 * Q
TC = 3 * 6
TC = 18
So the maximum profit is the difference between the total revenue and the total cost:
Profit = TR - TC
Profit = 36 - 18
Profit = 18
The maximum profit of the firm is $18 at an equilibrium price level of $6 and an output level of 6 units.
