Please help!! 13 points, will mark brainliest!! How to calculate [tex]cos (x)=\frac{6}{15}[/tex]?
I'm doing a trig question; trying to find angle XYZ, and I think the formula for the answer is C = [tex]\frac{A}{H}[/tex], which as stated in the title, I think in this situation is [tex]Cos(x)=\frac{6}{15}[/tex].
I don't know what I'm doing wrong, or if I've done the whole question wrong, but no scientific calculators will give me an answer because it says Cos is already defined. I know for sure the answer isn't 0.4, which was a guess I made. The entire question is attached below.
Answer:
66.4°
Step-by-step explanation:
Let ∠XYZ be x°.
Given the adjacent side, XY, and the hypotenuse side,YZ, we use cosine.
[tex] cosθ= \frac{adj}{hyp} \\ cosx° = \frac{6}{15} [/tex]
To find the value of x°, take the inverse of cosine.
[tex] x°\\ = cos^{ - 1} (\frac{6}{15} ) \\ = 66.4° \: (1 \: d.p.)[/tex]
Thus, ∠XYZ= 66.4°
*Given 2 sides, we can find the measure of an angle in a right- angled triangle by taking the inverse of the trigonometry function.

If f(x)=2x(With an exponent of 2) -3, find f(-2)
[tex]f\left(x\right)=2x^2-3f ( x ) = 2 x 2 − 3 find f\left(-2\right)f ( − 2 ).[/tex]
Answer:
5
Step-by-step explanation:
Put -2 where x is and do the arithmetic.
f(x) = 2x² -3
f(-2) = 2(-2)² -3 = 2(-2)(-2) -3 = 8 -3
f(-2) = 5
Answer:
f(-2) = 5
Step-by-step explanation:
We just need to substitute x with -2 and simplify.
f(x) = 2x² - 3
f(-2) = 2(-2)² - 3
f(-2) = 2(4) - 3
f(-2) = 8 - 3
f(-2) = 5

Please please help asap!!!! Solve for the indicated variable. 3a + 6b = 4 for b
Answer:
b = (4/6) - a/2
Step-by-step explanation:
6b + 3a = 4
6b = 4 - 3a
b. = (4 - 3a)/6
b. = (4/6) - a/2
The value of b is (4 - 3a)/6, or the equation in terms of a is (4 - 3a)/6 after making the subject as b.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
In the provided expression, variable and constant are there
It is given that:
The equation in a and b, where a and b are the variables:
3a + 6b = 4
Here the indicated variable is b.
To find the value of b in terms of a make the subject as b:
Subtract 3a on both the sides in the equation 3a + 6b = 4:
The equation becomes:
3a + 6b -3a = 4 - 3a
6b = 4 - 3a
Divide by 6 on both sides:
The equation becomes:
6b/6 = (4 - 3a)/6
b = (4 - 3a)/6
Thus, the value of b is (4 - 3a)/6, or the equation in terms of a is (4 - 3a)/6 after making the subject as b.

What is the equation of the line that passes through the point (-1,4) and has a slope of -5?
Answer:
y = -5x + 4
Step-by-step explanation:
In the equation y = mx + b , m stands for slope and b stands for the y intercept. In the coordinates (-1,4) the y value is 4 meaning that it's your y-intercept. The slope is already given to you so just add the X.
Answer:
y = -5x - 1
Step-by-step explanation:
Since you have the slope and a given point you can use the point-slope formula to solve for the y-intercept formula.
Point slope formula = y - y = m(x - x)
m = -5 (-1, 4)
y - 4 = -5(x +1)
y - 4 = -5x - 5
y = -5x - 1
ldentify the hypothesis of the statement
If the slope of a line is positive, then the line is not horizontal.
A) the line is not vertical
B) the line is not horizontal
C) the slope of a line is positve
D) the slope of a line is negative
Answer:
C the slope of a line is positive
Step-by-step explanation:
Hypothesis: The phrase following the "if" part of a conditional statement. So the answer would be c- The slope of a line is positive.
C) the slope of a line is positive
A conditional statement has two parts: hypothesis (if) and conclusion (then).
We have the given statement as:
If the slope of a line is positive, then the line is not horizontal.
Here, "if" part of a conditional statement is the slope of a line is positive
So, the hypothesis of the statement is the slope of a line is positive
Therefore the correct option is (C).

Sue is offered a job reshelving books in the University of Montana library from noon until 1 p.M. Each Friday. Her reservation wage for this task is $10 per hour. If the library director offers Sue $100 per hour, how much economic surplus will she enjoy as a result of accepting the job? Now suppose the library director announces that the earnings from the job will be divided equally among the 400 students who live in Sue's dormitory. Will Sue still accept? Explain how your answers to parts a and b illustrate one of the incentive problems inherent in income redistribution programs.
Answer:
Step-by-step explanation:
Sue's initial wage per hour = $10
Sue's wage per hour after the increase = $100
a. Economic surplus to be enjoyed = $100 - $10
= $90
Sue would enjoy an economic surplus of $90.
b. No, because in this case the wage per hour for each 400 student would be;
= [tex]\frac{100}{400}[/tex]
= $0.25
= 25 cents
Redistribution of income is the act of equal sharing of wealth among a certain number of people.
The problem here is that Sue would feel cheated with the division of the earnings among 400 students, but very happy when her wages was increased.
Though the income incentive redistribution programs reduce poverty, but it may be unfair.

Let f(x)=x²-x-12 and g(x)= x -4.
What value can the expression (f/g)(x) never equal?
Answer:
7
Step-by-step explanation:
This function can never equal 0. Why? well here:
(f/g)(x) also just means [tex]\frac{f(x)}{g(x)}[/tex]. In this case, we get [tex]\frac{x^2-x-12}{x-4}[/tex] Or [tex]\frac{(x+3)(x-4)}{x-4}[/tex]. It seems like you can cancel out x-4 and bam, you get x+3 and any value should work.
However, x can never equal 4 because 4 leads to a case where you divide by 0. This is called discontinuity. Thus, the value you can't get is x=4, or 7 because when you plug 4 in, you get 0/0. Otherwise, any other real value is defined by x+3.

Answer:
x = -5
Step-by-step explanation:
Since these two triangles are similar, the ratio between the corresponding lengths of each triangle will be the same.
This means the ratio between one side of each triangle (e.g. AD and DC) will be the same as the ratio between a different side of each triangle (e.g. BE and BC).
So, to create an equation for the sides which contain the unknown 'x', we must first find the ratio between the two sides by using a different set of sides.
On the right side we are given 9 for AD, and 18 for DC.
9/18 = 0.5
This means that the extra length of the larger triangle from the smaller one (AD) is half the length of the smaller triangle (DC). We can use this to make an equation for x:
If AD/DC = 0.5, then BE/EC will also = 0.5
BE = x+23
EC = x+41
Therefore:
[tex]\frac{x+23}{x+41} = 0.5[/tex]
Now we can solve by multiplying both sides by x+41 to eliminate the fraction:
[tex]x+23=0.5(x+41)[/tex]
Now we multiply out the brackets and move the terms to different sides:
[tex]x+23=0.5x+20.5[/tex]
[tex]0.5x = -2.5[/tex]
[tex]x = -5[/tex]
And if we substitute the -5 into the equations:
-5+23 = 18
-5 + 41 = 36
We will see that -5 does indeed give us the same ratio between the lengths:
18/36 = 0.5
Hope this helped!

6>x is the answer.
Answer:
[tex]\boxed { x < 6}[/tex]
Step-by-step explanation:
Solve the following inequality:
[tex]-6 < 3x - 4x[/tex]
-Combine like terms:
[tex]-6 < 3x - 4x[/tex]
[tex]-6 < -x[/tex]
-Switch sides:
[tex]-6 < -x[/tex]
[tex]-x > -6[/tex]
-When you are dividing an integer by a negative integer, then the inequality sign would change. So, to get the variable [tex]x[/tex] positive, divide both sides by [tex]-1[/tex]:
[tex]\frac{-x}{-1} > \frac{-6}{-x}[/tex]
[tex]\boxed { x < 6}[/tex]
