A music teacher sells piano lesson packages. Piano Lesson Packages Total Cost Number of Lessons $90: 10 $160: 20 $80: 10 $120: 20 Which package has the lowest ratio of cost to number of lessons? A. $90 for 10 lessons B. $160 for 20 lessons C. $80 for 10 lessons D. $120 for 20 lessons
Answer:
D. $120 for 20 lessons
Step-by-step explanation:
Based on the data provided we can decide which package is best by first calculating how much each package is charging per lesson. We do this by dividing the total dollar amount of each package by the number of lessons offered in that package. Then we simply compare each package to see which package charges the least amount for every single lesson like so...
$90 / 10 = $9 per lesson
$160 / 20 = $8 per lesson
$80 / 10 = $8 per lesson
$120 / 20 = $6 per lesson
Based on these values we can see that the cheapest package is $120 for 20 lessons which would be $6 per lesson.

Question
Enter a recursive rule and an explicit rule for the arithmetic sequence. Then, find the 20th term of the
sequence
55, 65, 75, 85,-
The recursive rule is f(1) =
f(n)=f(?
+
The explicit rule is f(n) =
+
?
f(20) =
Answer:
The recursive rule is [tex]f(1)[/tex] = first term; [tex]f_({n})[/tex] = [tex]f_({n-1})[/tex] + d
f(1) = 55; [tex]f_{20}[/tex] = [tex]f_{19}[/tex] + 10
The explicit rule is f(n) = f(1) + (n - 1)d
f(20) = 245
Step-by-step explanation:
The recursive rule of the arithmetic sequence is
[tex]a_{1}[/tex] = first term; [tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + d
Where:
[tex]a_{1}[/tex] is the first term in the sequence [tex]a_{n}[/tex] is the nth term in the sequence [tex]a_{n-1}[/tex] is the term before the nth term n is term number d is the common difference.The explicit rule of the arithmetic sequence is
[tex]a_{n}=a_{1}+(n-1)d[/tex]
where:
[tex]a_{1}[/tex] is the first term in the sequence [tex]a_{n}[/tex] is the nth term in the sequence n is term number d is the common difference∵ The first 4 terms of the sequence are 55, 65, 75, 85
∴ [tex]a_{1}[/tex] = 55
∵ d = 65 - 55
∴ d = 10
∵ We need to find the 20th term
∴ n = 20
∵ The recursive rule is [tex]f(1)[/tex] = first term; [tex]f_({n})[/tex] = [tex]f_({n-1})[/tex] + d
→ Substitute the values of [tex]a_{1}[/tex], n, and d in recursive rule
∴ f(1) = 55; [tex]f_{20}[/tex] = [tex]f_{19}[/tex] + 10
∵ The explicit rule is f(n) = f(1) + (n - 1)d
→ Substitute the values of n and d to find it
∴ f(20) = 55 + 19(10) = 245
∴ f(20) = 245

Answer:
x = 2
Step-by-step explanation:
Step 1: Convert to math
5x + 1 = 3x + 5
Step 2: Solve for x
Subtract 4x on both sides: 2x + 1 = 5Subtract 1 on both sides: 2x = 4Divide both sides by 2: x = 2Step 3: Check
Plug in x to verify it's a solution.
5(2) + 1 = 3(2) + 5
10 + 1 = 6 + 5
11 = 11
Answer:
2
Step-by-step explanation:
there are 5 x's and 1 positive one of the left side, and 3 x's and five positive one's on the right side. when you put this into an equation, you get:
5x+1 = 3x+5
the first step to solving the equation is to subtract 3x from both sides:
5x+1 -3x = 3x+5 -3x
2x+1 = 5
next, subtract 1 from both sides:
2x+1 -1 = 5 -1
2x=4
finally, divide both sides by 2:
2x ÷2 = 4 ÷2
x=2
and the answer is: 2

Answer:

Step-by-step explanation:
Answer:
The first one
Step-by-step explanation:
This is because, the symbol // means "parallel to" in geometry.
Parallel means when two line segments are corresponding with each other and they never meet. (beside one another)
The rest of the options don't make any sense. For example choice 2 states that FG is perpendicular to TU. Perpendicular would mean that the line creates a 90 degree angle when they intersect. So that's false, and the same goes for choice 3.
Choice 4 states that TU is parallel to FG, which is completely false because they both intersect.

The fourth choice. For example, (x+2)(x-2)>0 we'll get x>2 or x<-2 because whenever you substitute x>2 for example x = 3, the value will be higher than 0 itself.
If we substitute x = 3 (for x>2)
We'll get (3+2)(3-2)>0
5(1)>0
5>0 The statement is true.
If we substitute x = -3 (for x<-2)
We'll get (-3+2)(-3-2)>0
-1(-5)>0
5>0 The statement is true.
We don't say x>2 AND x<-2, In math, we only say x>2 OR x<-2
Answer:
x >2 and x < -2
Step-by-step explanation:
The line on the right starts on -2 and goes towards -10
So ; x is x < -2
The line on the right starts on 2 and goes towards 10
So ; x is x >2

A radar operator on a ship discovers a large sunken vessel lying parallel to the ocean surface, 120 m directly below the ship. The length of the vessel is a clue to which wreck has been found. The radar operator measures the angles of depression to the front and back of the sunken vessel to be 55° and 46°. How long, to the nearest tenth of a metre, is the sunken vessel?
Answer:
The length of the sunken vessel, to the nearest tenth is 200 m
Step-by-step explanation:
The given information are;
The depth of the sunken vessel below the ship = 120 m
The angle of depression to the front of the sunken vessel = 55°
The angle of depression to the back of the sunken vessel = 46°
Therefore, we have;
The length, A, of the from directly below the ship to the front of the sunken vessel given as follows;
Tan(55°) = ((120 m)/A)
A = 120 / Tan(55°) ≈ 84.025 m
The length, B, of the from directly below the ship to the back of the sunken vessel given as follows;
tan(46°) = ((120 m)/B)
B = 120 / tan(46°) ≈ 115.88 m
The length, L, of the sunken vessel = A + B
L = A + B = 120 / Tan(55°) + 120 / tan(46°) ≈ 84.025 m + 115.88 m ≈ 199.91 m
∴ The length, L, of the sunken vessel, to the nearest tenth = 200 m.

x=3
y=5
x=2
y=3
Answer:
x=3 and y=5 passes through(3,5)
x=2 and x=3 is perpendicular to y=3
so anwer is x=3
If f(x) = (2x² + 5), then f'(x)
=======================================
Work Shown:
f(x) = 2x^2 + 5
f ' (x) = d/dx[ 2x^2 + 5 ]
f ' (x) = d/dx[ 2x^2 ] + d/dx[ 5 ]
f ' (x) = 2*d/dx[ x^2 ] + d/dx[ 5 ]
f ' (x) = 2*2x^1 + 0
f ' (x) = 4x

I had the same question a couple years back and this paragraph really helped me out, hopefully it does the same for you. The coordinate plane is a way that we have to locate points in two dimensions. It consists of two intersecting lines that we call axes. The axes are number lines with positive and negative values. The horizontal line is referred to as the x-axis, and the vertical line is the y-axis. The coordinate plane is divided into four quadrants. These quadrants are named with Roman numerals and are numbered starting in the top, right section and moving counter-clockwise.
Question 4 Which is a TRUE statement about the transformation shown?
The graph shows a translation, and the pre-image and image are congruent.
The graph shows a reflection, and the pre-image and image are congruent.
The graph shows a translation, and the pre-image and image are similar.
The graph shows a reflection, and the pre-image and image are similar.
Answer:
reflection
Step-by-step explanation:
the second picture is the same distance away form the y axis as the first picture
The graph shows a reflection, and the pre-image and image are congruent.
The correct option is B.
What is a reflection?A reflection is a type of transformation that involves flipping a shape, known as the preimage, over a line, known as the line of reflection, to produce a new shape (called the image). You can picture what would happen if you flipped the form over the line in order to graph a reflection.
Given:
The transformation shown in the graph is reflection.
The graph shows a reflection, and the pre-image and image are congruent.
Because the distance between the vertices are equal and angles are equal.
Therefore, the pre-image and image are congruent.

Conjugate of complex number i^3 – 4 is
(a)i^3 + 4
(b) 4 – i
(c) -4+i
(d) -4 – i
Answer:
(c) -4+i is conjugate of complex number i^3 – 4 is
Step-by-step explanation:
-4+i^3
=-4+(i^2)i
=-4+(-1)i
=-4-i
Conjugate of x+iy= x-iy
So, conjugate of -4-i= -4+i
Hope it helps :-)
The conjugate of a complex number is a complex number with the same real part, but a negated imaginary part. The conjugate of [tex]i^3 - 4[/tex] is [tex]-4 + i[/tex]
Let the complex number be N. So:
[tex]N = i^3 - 4[/tex]
In complex numbers,
[tex]i = \sqrt{-1}[/tex]
Take cube of both sides
[tex]i^3 = (\sqrt{-1})^3[/tex]
Split
[tex]i^3 = (\sqrt{-1}) \times (\sqrt{-1}) \times (\sqrt{-1})[/tex]
[tex]i^3 = -1 \times (\sqrt{-1})[/tex]
Substitute [tex]i = \sqrt{-1}[/tex]
[tex]i^3 = -1 \times i[/tex]
[tex]i^3 = -i[/tex]
So, we have:
[tex]N = i^3 - 4[/tex]
[tex]N = -i - 4[/tex]
Rewrite as:
[tex]N = -4 - i[/tex]
A complex number a + bi has a- bi as its conjugate.
So, the conjugate of N is:
[tex]N' = -4 + i[/tex]
Hence, (c) is correct
