I need help please !!!!!!!!
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
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.

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?
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,

Which ordered pair is a solution of the equation?
y-3=5(x-2)
A. Only 2,3
B. Only 3,2
C. Both 2,3 and 3,2
D. Neither
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.

Final answer:
To evaluate a logarithm, use the calculator's log button for the common logarithm or calculate 10 raised to the power of the logarithmic value for the inverse log. Logarithmic properties simplify expressions by converting multiplication into addition and exponents into multiplication.
Explanation:
Understanding and Evaluating Logarithms
To evaluate a logarithm, one can use a calculator's log button to find the common logarithm, which is based on base 10. If you have a logarithm and wish to find the actual number it represents, you take the inverse log of the logarithm. This can also be expressed as 10 to the power of the logarithmic value.
For instance, to evaluate log(100), you would press the log button on your calculator and then enter 100. The result would be 2, since 10^2 = 100. If you have the logarithm value, say 3, and want to find the number it corresponds to, calculate 10^3, which equals 1000.
Furthermore, logarithmic properties can be used to simplify expressions and solve equations. If you take the log of two numbers being multiplied, you can add their individual logs. Additionally, taking the log of a number raised to an exponent allows you to move the exponent in front of the log, thus multiplying the exponent by the log of the number.
During the seventeenth century, the principle of the logarithm was developed by Napier. Logarithms transform multiplication into addition, which simplifies many computations, like using antilogarithms and slide rules for multiplication.

D) 3.1
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:
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.

Bo teaches 16 classes per week and Erica teaches 20 classes per week.
To find out how many yoga classes Bo and Erica each teach per week, we can set up a system of equations based on the given information.
Let B represent the number of classes Bo teaches per week. Let E represent the number of classes Erica teaches per week.
According to the problem, the total number of classes taught by Bo and Erica is 36:
Equation 1: B + E = 36
Also, we know that Erica teaches 12 fewer than twice as many classes as Bo:
Equation 2: E = 2B - 12
We can substitute the expression for E from Equation 2 into Equation 1:
B + (2B - 12) = 36
Simplify and solve for B:
B + 2B - 12 = 363B - 12 = 363B = 48B = 16So, Bo teaches 16 classes per week. Now we can find out how many classes Erica teaches by substituting B back into Equation 2:
E = 2(16) - 12
E = 32 - 12
E = 20
Therefore, Erica teaches 20 classes per week.
Thus, Bo teaches 16 classes per week and Erica teaches 20 classes per week.
