Answer:
34.6
Step-by-step explanation:
1) tan(38°)=27/x, then
2) x=27/(tan38°);
x=27/0.78129≈34.558=34.6
Given: cot32°=4/3 and cos44°=7/9 find sin62°
This question has the same problem as the other one you shared. Neither cot(32°) = 4/3 nor cos(44°) = 7/9 are true.
But if we indulge the author for a moment, we have from the double angle identity
[tex]\sin(2x) = 2\sin(x) \cos(x)[/tex]
so if x = 32°, then
[tex]\sin(64^\circ) = 2\sin(32^\circ) \cos(32^\circ)[/tex]
We also have from the Pythagorean identity
[tex]\sin^2(x) + \cos^2(x) = 1 \implies 1 + \cot^2(x) = \csc^2(x) \\\\ \implies \csc(x) = \pm \sqrt{1+\cot^2(x)} \\\\ \implies \sin(x) = \pm \dfrac1{\sqrt{1+\cot^2(x)}}[/tex]
Now, 0° < 32° < 90°, so both sin(32°) and cos(32°) are positive.
If we assume cot(32°) = 4/3 to be true, it follows that
[tex]\sin(32^\circ) = \dfrac1{\sqrt{1+\left(\frac43\right)^2}} = \dfrac35[/tex]
[tex]\cos(32^\circ) = \sqrt{1 - \sin^2(32^\circ)} = \dfrac45[/tex]
[tex]\implies \sin(64^\circ) = 2\times\dfrac35\times\dfrac45 = \dfrac{24}{25}[/tex]
so E is the only correct choice regardless of the baseless assumptions made by the question.

Step-by-step explanation:
We're given:
Two times a number minus four times another number is tenFour times the first number minus four times the second number results in fourLet the first number be x and the second be y.
Translate the given information into equations:
Two times [a number] minus four times [another number] is tenNow, solve using elimination:
- [tex]2x-4y=10\\\hspace{5} 4x-4y=4\\\rule{60}{0.3}\\-2x=6[/tex]
Solve for x:
[tex]-2x=6\\x=-3[/tex]
Therefore, the first number is -3.
Now, solve for y using x:
[tex]2x-4y=10\\2(-3)-4y=10\\-6-4y=10\\-4y=16\\y=-4[/tex]
Therefore, the second number is -4.

What is a rebound line?Water is released from the earth when it is squeezed or compacted by some force. As a further stage, the stress in the soil is removed, allowing the soil sample to expand back to its original size.
The soil will try to reclaim some of the stress it has lost after the stress has been released. Rebound is the word for this procedure.

Answer:
The value of the x is 2 and the value of the y is 0 in the system of equation 3y=x-2, y=-2x+4.
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have a system of the equation:
3y=x-2 ..(1)
y=-2x+4 ...(2)
From the equation (2) take the value of y and plug in the equation (1)
3(-2x+4) = x -2
-6x + 12 = x - 2
7x = 14
x = 14/7
x = 2
Plug this value in the equation (2)
y = -2(2) + 4
y = 0
Thus, the value of the x is 2 and the value of the y is 0 in the system of equation 3y=x-2, y=-2x+4.

what is the 14th term of the given sequence
64,-32,16,-8….
Answer:
[tex]-\frac{1}{128}[/tex]
Step-by-step explanation:
1) Identify the type of sequence this is; whether it is geometric progression, quadratic sequence or linear sequence.
= Geometric progression
2) Find the [tex]n^{th}[/tex] term of this sequence. Every sequence of geometric progression is written in [tex]u_{n} = u_{1} * r^{n-1}[/tex] form, where [tex]u_{1}[/tex] is the first term of the sequence and [tex]r[/tex] is the common ratio. To find the [tex]n^{th}[/tex] term of this sequence, we need to find the common ratio ([tex]r[/tex]) first.
[tex]r = \frac{u_{2}}{u_{1}}[/tex]
[tex]r = \frac{-32}{64}[/tex]
[tex]r = -\frac{1}{2}[/tex]
2.1) Write it in [tex]u_{n} = u_{1} * r^{n-1}[/tex] form.
[tex]u_{n} = 64 * (-\frac{1}{2} )^{n-1}[/tex]
3) Find the [tex]14^{th}[/tex] term by substituting 14 into the [tex]n[/tex]'s.
[tex]u_{14} = 64 * (-\frac{1}{2} )^{14-1}[/tex]
[tex]u_{14} = 64 * (-\frac{1}{2} )^{13}[/tex]
[tex]u_{14} = 64 * -\frac{1}{8192}\\u_{14} = -\frac{1}{128}[/tex]

The equation of the function g(x) is g(x) = -x² + 4 after applying the transformation.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The equation of the function f(x) = x² - 1
The equation of the function g(x) = -x² + 4
Let f(x) is the parent function.
To get the equation of the function g(x):
Applying transformation to function f(x)
f(x) → f(x) + 5 (function will shift up side by 5 units)
F(x) = x² - 1 + 5
F(x) = x² + 4
F(x) → -x² (funtion will reflect about the line y = 4)
g(x) = -x² + 4
Thus, the equation of the function g(x) is g(x) = -x² + 4 after applying the transformation.

A point located at (-5, -6) is reflected over the x-axis
(-5,6)
Step-by-step explanation:When a point is reflection a new, prime point (x') is created.
Formula
Whenever a point is reflected over the x-axis it follows a specific rule. The point goes from (x,y) to (x,-y). So, since the point is (-5, -6) we need to switch the sign of the y-value. This creates the new point (-5, 6).
Why?
Another way to remember this formula is to understand where it comes from. When reflecting over the y-axis, a point goes from the top 2 quadrants to the bottom 2 or vice versa. This means that the value is moving vertically. During vertical shifts, there is a change in the y-value. Additionally, because the x-axis is the seperation between negative and positive y-values, the y-value changes signs.
The first row of a conference hall has 11 chairs and 2 additional chairs in each subsequent row. How many chairs are in the 8th row? How many chairs in total are in the first 8 rows?
The total number of chairs in the eight rows of the conference hall is; 144 chairs.
What is the total number of chairs in the eight rows?From the task content;
It follows that the first row contained 11 chairs and each successive row has 2 more chairs. It therefore follows from the sum of terms for an arithmetic progression that the eight rows contain;
Total number of chairs = (8/2) × (2(11) + 7(2))

Determine whether F(x)=4x^2-16x+6 has a maximum or a minimum value and find that value
Answer:
f(x) has a minimum value of -10.
Step-by-step explanation:
It will have a minimum value because the coefficient of x^2 is positive.
To find its value we convert to vertex form:
f(x) = 4x^2 - 16x + 6
= 4(x^2 - 4x) + 6
= 4[(x - 2)^2 - 4] + 6
= 4(x - 2)^2 - 16 + 6
= 4(x - 2)^2 - 10.
So the minimum value is -10.
313,307,301 find the 42nd term
Answer:
-252
Step-by-step explanation:
assuming that 313, 307, and 301 are the first 3 terms..
By these three numbers we can conclude that the rule is -6
(313 - x = 307, 313 - 307 = 6.. x = 6. To check this we do the same thing but with 307 and 301. 307 - x = 301, 307 - 301 = 6, 6 = x)
We find the 42nd term by multiplying our rule by the term number (42)
-6(42) = -252
Remember that a negative times a positive is a negative, but a negative times a negative is positive.
The 42nd term of an arithmetic sequence is 72.
What is an arithmetic sequence?A series of integers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.
Given, the sequence is an arithmetic sequence.
a₁ = 313
a₃ = 301 so n= 3
Remember that,
aₙ= a₁ + (n-1)d
aₙ=a₁+(n−1)d
301 = 313 + (3 -1)d
301 = 313 + (2d)
301 - 313 = 2d
-12 = 2d
d = -6
So to find a₄₂:
Then, use the same formula for n = 42
a₄₂ = 313 + (42 - 1) (-6)
a₄₂ = 313 - 246
a₄₂ = 72
Therefore, 72 is the 42nd term of an arithmetic sequence.
