Answer:
see explanation
Step-by-step explanation:
The most likely error is adding the exponents instead of multiplying them, that is
[tex](a^{m}) ^{n}[/tex] = [tex]a^{mn}[/tex] , then [tex](3^{3}) ^{1}[/tex] = [tex]3^{3(1)}[/tex] = 3³ = 27
However
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex] ← the student may have used this definition to obtain 81

18) The school that John goes to is selling tickets to the annual talent show. On the first day of ticket
sales the school sold 3 senior citizen tickets and 5 student tickets for a total of $71. The school
took in $190 on the second day by selling 10 senior citizen tickets and 12 student tickets. Find
the price of a senior citizen ticket and the price of a student ticket.
Answer:
Student ticket=$10. Senior ticket=$7
Step-by-step explanation:
If we say Student ticket price = Y. and senior ticket price = X. Then we can say:
[tex]3x+5y=71\\10x+12y=190[/tex]
We can rewrite one of the equations as y equals:
[tex]10x=190-12y[/tex]
Then, we simply solve for x.
[tex]\frac{10x=190-12y}{10}=x=19-1.2y[/tex]
Then, we use the other equation and replace x with the equation we just solved
[tex]3(19-1.2y)+5y=71\\[/tex]
We simplify and it becomes:
[tex]57-3.6y+5y=71[/tex]
Then we subtract 57 from each side and get:
[tex]-3.6y+5y=-14[/tex]
Next, we combine the y and get:
[tex]1.4y=14[/tex]
Then we divide by 1.4 and get:
[tex]\frac{1.4y=14}{1.4} =y=10[/tex]
This means that the cost per student ticket is $10
Next we replace the y value in an equation with 10 and solve:
[tex]3x+5y=71\\3x+5(10)=71\\3x+50=71\\[/tex]
Then we subtract 50 from each side:
[tex]3x+50=71\\-50\\3x=21[/tex]
Finally, we divide each side by 3:
[tex]\frac{3x=21}{3} =x=7[/tex]
This means that each senior ticket costs $7

Given z=-4-6i
Write down the conjugate of z
Answer:
z = -4 + 6i
Step-by-step explanation:
A math conjugate is formed by changing the sign between two terms in a binomial. For instance, the conjugate of x+y is x−y . We can also say that x+y is a conjugate of x−y . In other words, the two binomials are conjugates of each other.
Eva is 5 years younger than 3 times Bill's age. If Eva is 2 years old, how old is Bill?
Answer:
17 years old.
Step-by-step explanation:
5 years than 3 times can be represented as 5*3.
5*3=15.
If Eva is 2, and Bill is 15 years older, 2+15=17.
Therefore, Bill is 17 years of age.

in a for loop, is it possible to use indexing?
Answer:
Yes
Step-by-step explanation:
A for loop basically relies on repeating the same code for a pre-set number of times. During which you can make any code repeat inside of it, including indexing through a type of list. Many times a for-loop will use the indexes in a list to calculate the number of times that the loop has to repeat. This is usually done in order to search or apply changes in an array of other types of data structures that have countless values stored in it.

Given a graph for the transformation of f(x) in the format g(x) = f(x) + k, determine the k value.
two parabolas open up with f of x passing through negative 3 comma negative 3 and g of x passing through negative 3 comma 1
A. k = −3
B. k = 1
C. k = 4
D. k = 5
Look up to their vertexes
f(x) has vertex at (-3,-3)g(x) has vertex at (-3,1)So
[tex]\\ \rm\rightarrowtail g(x)=f(x)+k[/tex]
[tex]\\ \rm\rightarrowtail g(-3)=f(-3)+k[/tex]
[tex]\\ \rm\rightarrowtail 1=-3+k[/tex]
[tex]\\ \rm\rightarrowtail k=1+3[/tex]
[tex]\\ \rm\rightarrowtail k=4[/tex]
The required value of K for the transformation of f(x) is 4. Option C is correct.
Given that,
Graph for the transformation of f(x) in the format g(x) = f(x) + k,
To determine the k value.
Two parabolas open up with f(x) passing through (- 3, - 3)and g(x) passing through (-3, 1).
A parabola is a cross section cut out of the cone and represented by an equation
Here,
Since equation of transformation is g(x) = f(x) + k
Now put the values of the vertex in the transformation equation,
f(x) passing through (- 3, - 3)and g(x) passing through (-3, 1).
f(-3) = -3
g(-3) = 1
g(-3) = f(-3) + k
1 = -3 + k
k = 1 + 3
k = 4
Thus, the required value of K for the transformation of f(x) is 4. Option C is correct.

The side length of an equilateral triangle is 5 centimeters. Find the length of an altitude. Round your answer to the nearest tenth.
The length of the altitude is about
centimeters.
If the side length of an equilateral triangle is 5 centimeters, the length of altitude is about 4.33 centimeters.
What is an equilateral triangle?An equilateral triangle can be defined as a type of triangle or regular polygon that has equal side lengths and all of its interior angles are equal.
How to calculate the length of altitude.Mathematically, the length of altitude of an equilateral triangle is calculated by using this formula:
[tex]L=\frac{\sqrt{3} }{2} a[/tex]
Where:
a is the side lengths.L is the length of altitude.Given the following data:
Side length = 5 centimeters.Substituting the given parameters into the formula, we have;
[tex]L=\frac{\sqrt{3} }{2} \times 5\\\\L=\frac{5\sqrt{3} }{2}[/tex]
Length = 4.33 centimeters.

[tex]\mathrm{Divide\:both\:sides\:by\:}-1[/tex]
[tex]\frac{-x}{-1}=\frac{-15}{-1}[/tex]
[tex]Simplify[/tex]
[tex]x=15[/tex]
Answer:
Okay so yes the answer is 15
Step-by-step explanation:
It begins with 4X11 which is 44
So the equation becomes 44-x+4=33
Then I add 44 plus 4 which is me adding all the available terms which is 48
Then I subtracted 33 from 48 to find the value of x
And 48-33=15
So there you pretty much have it.
To be sure you can plug the answer in.
4x11=44
44-(x) which is 15 so 44-15=29
29+4=33

A different camera is selling for $7.50 off the regular price. It was marked down 15%. A student used the equation:
15(7.5) = Original price
and found the regular price of the camera to be $112.50.
Explain the error(s) in the student’s work.
Answer:
The original price is $50. The student's mistake in the equation is that he should have done 7.5/0.15
The student should not have multiplied, instead divided. He also didn't put 15 in a decimal form, which would have messed the whole equation up.
Answer:
The student should have divided the discounted amount by the percent. The percent should have been written as a decimal.
