Answer:
[tex]\sf \tan(C)=\dfrac{3}{4}[/tex]
Step-by-step explanation:
First, find the missing side length (DE) by using Pythagoras' Theorem:
a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
⇒ 36² + DE² = 45²
⇒ DE² = 45² - 36²
⇒ DE² = 729
⇒ DE = √729
⇒ DE = 27
Tan trig ratio
[tex]\sf \tan(\theta)=\dfrac{O}{A}[/tex]
where:
[tex]\theta[/tex] is the angleO is the side opposite the angleA is the side adjacent the angleGiven:
[tex]\theta[/tex] = CO = DE = 27A = 36Substituting the given values into the formula:
[tex]\implies \sf \tan(C)=\dfrac{27}{36}=\dfrac{3}{4}[/tex]
Answer:
3/4
Step-by-step explanation:
Finding the missing side by applying the Pythagorean Theorem :
a² + b² = c²a² = c² - b²a² = (45)² - (36)²a² = 2025 - 1296a² = 729a = 27Finding tan C :

The provided log can be written as sum of (1/5)log₃(x) + log₃(y) after using the log property.
What is a logarithm?It is another way to represent the power of numbers, and we say that 'b' is the logarithm of 'c' with base 'a' if and only if 'a' to the power 'b' equals 'c'.
[tex]\rm a^b = c\\log_ac =b[/tex]
We have:
[tex]= \rm log_3(\sqrt[5]{x} . y)[/tex]
As we know:
log(mn) = logm + logn
logmⁿ = nlogm
[tex]= \rm log_3({x^{\dfrac{1}{5}}} . y)\\\\= \rm log_3({x^{\dfrac{1}{5}}} )+log_3 (y)\\\\= \rm \dfrac{1}{5}log_3({x^{}} )+log_3 (y)\\\\[/tex]
Thus, the provided log can be written as sum of (1/5)log₃(x) + log₃(y) after using the log property.

John paid $34 for two algebra and three geometry books. he paid $36 for three algebra and two geometry
Answer:
Each geometry book costs $6, each algebra book costs $8.
Let a=cost of one algebra book and g=cost of one geometry book. We have:
2a + 3g = 34-------->6a + 9g = 102
3a + 2g = 36-------->6a + 4g = 72
-------------------
5g = 30
g = 6
2a + 3(6) = 34
2a + 18 = 34
2a = 16--->a = 8
Question: John paid $34 for two algebra and three geometry books. He paid $36 for three algebra and two geometry books. What is the cost of each book?
Answer: The cost of each algebra book is $8 and the cost of each geometry book is $6.
Step-by-step explanation:
a= algebra book cost
g= geometry book cost
Here's what we know:
2a + 3g = 34 (the 2 alg and 3 geo comes to $34)
3a + 2g = 36 (the 3 alg and 2 geo comes to $36)
This is a classic elimination method problem. I suggest that we multiply the first equation by -2 and the second by 3. This way, we can eliminate the variable g and still keep the other parts of the problem in the positive range:
-4a - 6g = -68
9a + 6g = 108
-------------------
5a = 40
Divide by 5:
a = 8
Now to solve for g:
2 * 8 + 3g = 34
16 + 3g = 34
3g = 18
g = 6
check (by using the second equation):
3 * 8 + 2 * 6 = 36
24 + 12 = 36

find x so that x+3, 2x+1, and 5x+2 are consecutive terms of an arithmetic sequence
Answer:
x = -3/2
Step-by-step explanation:
x + 3 + d = 2x + 1 First term plus common difference = 2nd term
x -2 = d
x + 3 + 2d = 5x+2 First term + 2 d = third term re-arrange:
4x-1 = 2d sub in the definition of d from above
4x -1 = 2 (x-2)
4x-1 = 2x-4
2x = -3
x = -3/2
If x+3, 2x+1, and 5x+2 are consecutive terms of an arithmetic sequence then x is -3/2.
What is Sequence?Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
The sequence in which consecutive terms will have common difference is called as Arithmetic sequence.
x+3, 2x+1, and 5x+2
The common difference between first term and second term
d=2x+1-x-3
d=x-2
The common difference between second term and third term
5x+2-2x-1=d
3x+1=d
Now plug in d value
3x+1=x-2
Subtract x from both sides
3x-x=-3
2x=-3
Divide both sides by 2
x=-3/2
Hence, if x+3, 2x+1, and 5x+2 are consecutive terms of an arithmetic sequence then x is -3/2.

The following data points represent the number of quesadillas each person at Toby's Tacos ate.
Sort the data from least to greatest.
0,0, 1/2, 1/2, 1/4, 1, 1, 1, 5/4, 2, 2.
What is the interquartile range of this data?β
The interquartile range for the given data is 1 quesadilla.
What is the interquartile range?The interquartile range is a measurement of a data set's "middle fifty." A range is a measurement of where a set's beginning and end are located.
To get the interquartile range, we must know the first and third quartiles. To find those, we need to know the median of the data.
There are 11 data points, so we can cross out 5 numbers on the left and cross out 5 numbers on the right. That leaves a median of 1.
Since we know the median is 1, we can find the first quartile by finding the median of the following numbers:
0, 0, 1/4, 1/2, 1/2 (any number less than 1).
There are five numbers, so cross out two numbers from the left and cross out two numbers from the right. We are left with the first quartile of 1/4.
Now that we have the first quartile, we need to find the third quartile. Since the median was actually the first "1" in the data set, the third quartile will be the median of the numbers to the right of that "
1: 1, 1, 5/4, 2, 2.
Cross out the leftmost two numbers, and cross out the rightmost two numbers. We are left with the third quartile of 5/4.
Now that we have both the third and first quartiles, we can find the interquartile range! The IQR is calculated by finding the third quartile minus the first quartile.
5/4 - 1/4 = 4/4 = 1.
Therefore, the interquartile range is 1 quesadilla.

A researcher posts a radio advertisement offering $35 in exchange for participation in a short study. The researcher accepts the first eight people who respond to the advertisement. Which of the following statements is true about the sample? It is a valid sample because the first eight people were selected to participate. It is not a valid sample because it is not a random sample of the population. It is a valid sample because money was offered to participants. It is not a valid sample because it is only a short study.
Answer: Choice B
It is not a valid sample because it is not a random sample of the population.
Explanation:
The researcher should have randomly selected the participants, either by picking names out of a hat, using a random number table, or some kind of computer software to pick the names. Letting the first 8 people form the sample is very likely not representative of the population at large. We have a lot of bias here. Therefore, this is not a valid sample.
