x=31.6
Im not sure since i have not taken a trig course yet, but i know the basics:
Tangent is opposite over adjacent, and in respect to this angle, (31 degrees) the opposite side is 19 and adjacent is x.
Tan(31) = 19/x
Solve for x...use a calculator to find tan(31)

What is the value of log Subscript 3 Baseline 81?

Answers
Answer:
4
Step-by-step explanation:
Using the rule of logarithms
[tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]
Given
[tex]log_{3}[/tex] 81 = n, then
81 = [tex]3^{n}[/tex]
Note that 81 = [tex]3^{4}[/tex] , thus
[tex]3^{4}[/tex] = [tex]3^{n}[/tex]
Since the bases are equal then equate the exponents
n = 4
The value of log Subscript 3 Baseline 81 (i.e Log₃ 81) obtained is 4
Data obtained from the question Log₃ 81 =? How to determine the value of Log₃ 81Let Log₃ 81 be equal to n i.e
Log₃ 81 = n
The value of n can be obtained as follow:
Log₃ 81 = n
81 = 3ⁿ
Express 81 in index form with 3 as the base
3⁴ = 3ⁿ
Cancel out 3
n = 4
From the calculation made above, we can conclude that the value of log Subscript 3 Baseline 81 (i.e Log₃ 81) is 4

According to the bar chart, what is the median of number of times a teenager reminded to do chores a week?
A) 1
B) 2
C) 3
D) 3.1
Answers
Answer: C
Step-by-step explanation: I did the math
The middle values are both 3, so the median is 3.
Option C is the correct answer.
What is a median?It is the middle value of the given set of numbers after arranging the given set of numbers in order.
We have,
To find the median of the number of times a teenager is reminded to do chores a week, we need to arrange the responses in order from smallest to largest, and then find the middle value.
From the bar graph, we can see that the number of reminders ranges from 0 to 5, and the frequencies are not evenly distributed.
To determine the median, we need to count the total number of responses and find the middle value.
The total number of responses is:
2 + 5 + 8 + 14 + 7 + 4 = 40
Since there are an even number of responses, we need to find the average of the two middle values.
The two middle values are the 20th and 21st values when we arrange the responses in order:
0, 0, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 5, 5

A bag has 24 marbles: 6 green, 6 red, and 12 blue. Lucy reaches in the bag and picks out 1 marble. Answer the following:
What is the total number of marbles?
What is half the total number of marbles?
Name an event that is impossible:
Name an event that is certain:
Name an event that is as likely as not:
Name an event that is more likely than not:
Name an event that is unlikely:
Answers
Final answer:
The bag has 24 marbles, with 12 marbles constituting half of the total. An impossible event would be drawing a marble color not present in the bag, while a certain event is the act of drawing a marble itself. A likely event is drawing a blue marble due to its greater number in the bag.
Explanation:
The total number of marbles in the bag is 24 marbles. Half the total number of marbles would be 12 marbles.
An impossible event would be Lucy picking out a marble that is not green, red, or blue since those are the only colors available in the bag.
A certain event is Lucy picking a marble from the bag, as there are marbles to be picked.
An event that is as likely as not is Lucy picking out a red marble since the probability of picking a red marble is 6 out of 24, which simplifies to 1 out of 4.
An event more likely than not is Lucy picking out a blue marble, given there are 12 blue marbles out of 24.
An unlikely event is Lucy picking out a green marble since there are only 6 green marbles out of 24.

Answers
Answer:
a= 1
b= 3
c= 1
d=2
e= 6
f= 8
Step-by-step explanation:
Plug the x value into the equation above the letter that you solve for.
This would give
a = 2^0 = 1 (since any number to the zero power is 1)
b = 3* 2^0 = 2 (we already know what 2^0 is we just have to multiply it with 3)
c= 2^ (3*0) = 2^0= 1 (when 3x is saying that you multiply the x value by zero then raise 2 to what that equals. any number times zero is zero and any number raised to the zero power is 1.
d= 2^1 = 2 (any number to the first power is that number)
e= 3* 2^1(we already know the value of 2^1 is we just have to multiply it with 3)
f= 2^(3*1)= 2^3 = 8 ( same rules as with c just multiply x, which equals 1 in this case with 3. 1 times any number is that number so you get 3. then raise 2 to the 3rd power which is 8.

Which is the principal value of arctan (3.7)?
PLEASE HELPP CANT GET IT WRONG
Answers
Answer:
1.42π rad
Step-by-step explanation:
Principal value are known to be the largest value that can be equivalent to the trigonometry expression given.
Given
θ = arctan (3.7)
θ = 74.9°
The principal value of the angle can be found in the 3rd quadrant.
In the third quadrant, the angle gotten will become 180° + 74.9°
= 254.9°
Converting to radians
Since πrad = 180°
x = 254.9°
180x = 254.9π
x = 254.9π/180
x = 1.42π rad
The principal value of the angle is 1.42π rad.

Answers
Answer
A only (2,3)
Step-by-step explanation:
If you graph it or plug it into Desmos that can also help
The ordered pair (2,3) is a solution to the equation y-3=5(x-2), but the ordered pair (3,2) is not. Therefore, the correct answer is option A: Only (2,3).
Explanation:In this Mathematics problem, we are asked to find which ordered pair is a solution to the equation y-3=5(x-2). An ordered pair is written in the form (x, y), so we'll test each option to see which one, if any, is a solution to the equation.
Let's start with option A, (2,3). If we substitute x with 2 and y with 3, we will have 3-3 = 5(2-2), which simplifies to 0 = 0. This equation is true, so the ordered pair (2,3) is a solution.
Next, we'll look at option B, (3,2). If we substitute x with 3 and y with 2, we will have 2-3 = 5(3-2), which simplifies to -1 = 5. This equation is not true, so the ordered pair (3,2) is not a solution.
Option C suggests that both (2,3) and (3,2) are solutions, but we've already established that (3,2) is not a solution to the equation.
So, based on our calculations, the correct answer is option A: Only (2,3) is a solution.

An online store holds a sale. Of the 400 customers who make purchases during the sale, 80 use a coupon. What percent of the customers do not use a coupon?
Answers
Answer:
80%
Step-by-step explanation:
If there are 400 people total and 80 of them have coupons, then 320 people don’t have coupons. Divide 320 by 400 and you will get 0.8, which is 80%.
The required percentage of the customers not using coupon is 80%.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
A percentage can be converted into a fraction or a decimal by dividing it by 100.
Given that,
The total number of customers is 400.
And, those using coupon are 80.
Then, number of customers not using coupon are 400 - 80 = 320
Thus, the percentage of the customers not using coupon is given as,
320/400 × 100
= 8/10 × 100
= 80%
Hence, percent of the customers do not use a coupon is 80%.
