Answer:
Because θ lies in quadrant II, 2θ must lie in quadrant IV. This means the tangent of 2θ is negative.
The adjacent side to θ is 7 because √(25²-24²)=7, so tanθ=7/24.
The double angle formula for tangent is tan 2θ = (2 tan θ) / (1 − tan² θ).
Substituting the value for tanθ in and keeping in mind that this is in quadrant IV, we get tan 2θ = -(2(7/24)/(1-(7/24)²)).
Simplified, this becomes tan 2θ = -336/527.
Therefore, the answer is C. -336/527.

determine whether each number is a solution of the given inequality
2m-4 ≥ 10
Answer:
m = 7
Step-by-step explanation:
2m + -4 = 10
Reorder the terms:
-4 + 2m = 10
Solving
-4 + 2m = 10
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 2m = 10 + 4
Combine like terms: -4 + 4 = 0
0 + 2m = 10 + 4
2m = 10 + 4
Combine like terms: 10 + 4 = 14
2m = 14
Divide each side by '2'.
m = 7
Simplifying
m = 7

Step-by-step explanation:
just subtract 125,000 by 36,000
although Its a guess
Answer:
$89,000
Step-by-step explanation:
To find your equity, subtract the outstanding balance from your home value:
125,000 - 36,000
= 89,000
So, your equity is $89,000

Answer:
Mixed number: [tex]3\frac{15}{100}[/tex]
Improper fraction: [tex]\frac{315}{100}[/tex]
Step-by-step explanation:
A mixed number is a number that contains an integer part and a fraction part.
An improper fraction is a fraction where the numerator is greater than the denominator.
[tex]3.15[/tex] can be written as [tex]\frac{315}{100}[/tex] in its fraction form. This would be an improper fraction since the numerator is greater than the denominator.
The mixed number is [tex]3\frac{15}{100}[/tex] since [tex]100[/tex] goes into [tex]315[/tex] three full times and the remainder is [tex]15[/tex].
∴The mixed number is [tex]3\frac{15}{100}[/tex] and the improper fraction is [tex]\frac{315}{100}[/tex].

To encourage Jack to read during the summer, his father offers an incentive (reward). He will pay Jack $5 for the first book he reads. For each
additional book Jack reads, his father will pay him an amount that is equal to some percentage, x, of the amount he paid for the previous book. Jack's
father agrees to let Jack choose a value for x, and Jack would obviously like his total earnings to be as large as possible.
Which of these options will allow Jack to earn an unlimited amount of money from his father, as long as he reads more and more books?

please andwer this for me <3
Answer:
C
Step-by-step explanation:
16 : 12
x : 6
- multiply 16*6 and divide by the number multiplying with the unknown (12)
(16*6)/12 = 8
- area of triangle is 1/2 h*b
so 1/2 * (16*8) = 64
Which of the following systems of linear inequalities is represented by the
solution graphed below?
Answer:
C.
Step-by-step explanation:
We know it's y > 2 cuz the red line is y and it's dashed so its just > not > with a line under.
The blue line is solid so it's > with a line under. The blue line also represents y and the shaded region is above the line so its y > or equal x.
Hope that makes sense
The inequalities represented by the graph are; y < 2 and y >= x.
So option C is correct.
What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true.
Such values are called solution to that equation or inequality.
The Set of such values is called solution set to the considered equation or inequality.
The graph as shown in the task content includes the horizontal line; y = 2 and the line; y = x.
However, the area shaded in the graph coincides with the upper area of y = 2 with broken lines as boundary and the lower area of line; y = x with a solid boundary line.
Hence, The inequalities represented by the graph are; y < 2 and y >= x.
So option C is correct.

Which of the following notations correctly describe the end behavior of the
polynomial graphed below?
Answer: Option B.
Step-by-step explanation:
In the graph we can see the graph of a quadratic equation (from this we could conclude that the graph will not change the current direction for the arms, so the arms will keep going down), and we also can see that as x increases in absolute value, the value of y decreases.
Then we could conclude that as IxI is really big, we will have that f(x) goes to minus infinity
x -->∞, f(x) --> -∞
x--> -∞, f(x) --> -∞
Then the correct option is B
Answer:
Option B!

What is the inverse of this function?
Answer:
[tex]f^{-1}(x)=4x^2-3[/tex]
Step-by-step explanation:
The Inverse of a Function
Given a function f(x), the inverse of f, called [tex]f^{-1}(x)[/tex] is a function that satisfies:
[tex]f(f^{-1}(x))=x[/tex]
The domain of f becomes the range of its inverse and vice-versa.
The procedure to find the inverse of the function is:
* Write the function as a two-variable equation:
* Solve the equation for x.
* Swap the variables
We are given the function:
[tex]\displaystyle f(x)=-\frac{1}{2}\sqrt{x+3}[/tex]
Defined in the interval x ≥ -3
Note f is always negative, thus its range is f(x) ≤ 0
Now we find the inverse. Call y=f(x):
[tex]\displaystyle y=-\frac{1}{2}\sqrt{x+3}[/tex]
Multiplying by 2:
[tex]\displaystyle 2y=-\sqrt{x+3}[/tex]
Squaring both sides:
[tex]\displaystyle 4y^2=x+3[/tex]
Subtracting 3:
[tex]\displaystyle 4y^2-3=x[/tex]
Swapping variables:
[tex]y=4x^2-3[/tex]
Thus:
[tex]\mathbf{f^{-1}(x)=4x^2-3}[/tex]
The domain of the inverse is the range of f, thus x is restricted to
x ≤ 0
