Acute triangle is the answer
Answer:
The answer is a. right.
Step-by-step explanation:
GIVEN:
hypo=25
opposite and adjacent=15 and 20.
FORMULA:
hypotenuse^2 =opposite side^2 + adjacent side^2
25^2=15^2+20^2
625=225+400
400+225=625

Trigonometry involves the study of angles and sides of triangles, where sine, cosine, and tangent are fundamental ratios used to solve problems. The Law of Sines and the Law of Cosines help calculate unknown lengths and angles in various types of triangles.
Explanation:Trigonometry is the branch of mathematics that deals with the relationships between the sides and angles of triangles, particularly right-angled triangles. Key concepts such as trigonometric ratios including sine, cosine, and tangent are fundamental in solving problems in trigonometry. When provided with a diagram like Figure 4.17 or Figure 5.27, one can determine the magnitudes of various components by applying these trigonometric principles.
For instance, if we know the angle and a side length adjacent to it, we can find the lengths of the unknown sides using functions such as cosine for the adjacent side or sine for the opposite side relative to the given angle. The Law of Sines and the Law of Cosines are also substantial tools in trigonometry, allowing us to calculate unknown lengths and angles in non-right triangles. Practicing these calculations with a calculator, as mentioned, helps familiarize oneself with the trigonometric functions and their inverses.
What is the exponential regression equation for the data set x 3,4,7,11,12,16,19 y .3,.5,.9,1.2,1.7,1.7,1.9
Answer:
The exponential regression equation for the data set is;
[tex]y=0.3258e^{0.1074x}[/tex]
Step-by-step explanation:
Exponential regression can easily be carried out in Ms. Excel. The first step is to enter the data in any two adjacent columns with the headers x and y in order to differentiate the response from the predictor variable.
The next step is to highlight the data, click the insert ribbon and choose the scatter-plot feature. This step will create an x, y scatter-plot for the data. The next step we click on the Add-Chart Element feature and add an exponential trend line to the scatter-plot while ensuring the Display Equation on chart is checked.
Ms. Excel provides the following exponential regression equation that models the data;
[tex]y=0.3258e^{0.1074x}[/tex]
Which statement best describes how to determine wether f(x)=x^3 +5x+1 is an even function
Answer: second option.
Step-by-step explanation:
By definition, a function is even when:
[tex]f(x) = f(-x)[/tex]
Then, knowing this, given the function [tex]f(x)=x^3 +5x+1[/tex] you can substitute [tex]-x[/tex] into this function:
[tex]f(-x)=(-x)^3 +5(-x)+1[/tex]
Now you need to simplify the function. Then you get:
[tex]f(-x)=-x^3 -5x+1[/tex]
In this case, you can see that:
[tex]f(x)\neq f(-x)[/tex]
Therefore, the function [tex]f(x)=x^3 +5x+1[/tex] is not even.
As you observed in the procedure above, the statement that best describes how to determine whether the given function is even is:
Determine is [tex](-x)^3 +5(-x)+1[/tex] is equivalent to [tex]x^3 +5x+1[/tex]

what is the solution to this equation -13x =25
Answer:
-1 12⁄13
Step-by-step explanation:
-13x = 25 [Divide by -13]
x = -1 12⁄13
13 is your divisor, which will be your denominator, and the numerator is your remainder. Since 13 goes into 25 ONCE, 1 gets multiplied by 13 to get 13, then deduct that from 25 to get your remainder of 12. This is where you start putting the pieces together as a mixed number. Then attach the negative because whenever you divide a positive by a negative, you get a negative:
-25⁄13 = -1 12⁄13

D (2 x 10) + (3 x 1) + (0 x 1\1) + (1 x 1) + (4 x 100)
Please help
b(2 ×10)+(3*1)+(0×1b)+(1×100)+(4×1000)
Final answer:
The number 23.014 in expanded form is (2 x 10) + (3 x 1) + (0 x 0.1) + (1 x 0.01) + (4 x 0.001), illustrating the value of each digit according to its place value.
Explanation:
Writing the number 23.014 in expanded form means expressing each digit according to its place value. Expanded form represents a number by showing the value of each digit. For the decimal number 23.014, we look at the place value of each digit: the digit in the tens place, the ones place, the tenths place (one place after the decimal), the hundredths place (two places after the decimal), and so on.
The correct expanded form for 23.014 is:
<(2 x 10) + (3 x 1) + (0 x 0.1) + (1 x 0.01) + (4 x 0.001)
This means:
The '2' is in the tens place, so it represents 2 x 10, or 20.
The '3' is in the ones place, so it represents 3 x 1, or 3.
The '0' is in the tenths place, but since it's 0, it adds no value (0 x 0.1 = 0).
The '1' is in the hundredths place, so it represents 1 x 0.01, or 0.01.
Finally, the '4' is in the thousandths place, so it represents 4 x 0.001, or 0.004.
Therefore, 23.014 written in expanded form is (2 x 10) + (3 x 1) + (0 x 0.1) + (1 x 0.01) + (4 x 0.001).

You can use the Distance Formula to find the length of such a line. This formula is basically the Pythagorean Theorem, which you can see if you imagine the given line segment as the hypotenuse of a right triangle. By using a basic geometric formula, measuring lines on a coordinate path becomes a relatively easy task.

Maximum number of possible solutions x^2+4y^2=64 x+y=5
Answer:
2
Step-by-step explanation:
We don't need to "solve" this to figure out the answer.
We need to recognize that the first equation given is that of an ellipse and the second equation given is that of a line.
A line and an ellipse in a coordinate system can have these outcomes:
1. They can intersect (touch) at 1 point
2. They can intersect at 2 points
3. Can't intersect at all
Thinking will make sense. So, the maximum number of possible solutions is 2.
Note: The number of points of intersection are the solutions as well
if a sequence is defined recursively by (0)=3 and (n+1)=-f(n)+5 for n≥0, Then f(2) is equal to
Answer:
f(2) = 3
Step-by-step explanation:
We are given:
f(0) = 3
and
f(n+1) = -f(n) + 5
We have to find the value of f(2). In order to find f(2) we first have to find f(1)
f(n + 1) = - f(n) + 5
Using n = 0, we get:
f(0 + 1) = - f(0) + 5
f(1) = -f(0) + 5 Using the value of f(0), we get
f(1) = -3 + 5 = 2
Now using n = 1 in the function, we get:
f(1 + 1) = - f(1) + 5 Using the value of f(1), we get
f(2) = -2+ 5
f(2) = 3
Thus the value of f(2) will be 3

Find the derivative of f(x) = negative 9 divided by x at x = -8.
Answer:
[tex]f'(-8)=\frac{9}{64}[/tex]
Step-by-step explanation:
Given the function
[tex]f(x)=\frac{-9}{x}[/tex]
We can rewrite it as
[tex]f(x)=-9x^{-1}[/tex]
Now we can apply the power rule
[tex]f'(x)=9x^{-2}[/tex]
Now we can rewrite it
[tex]f'(x)=\frac{9}{x^{2} }[/tex]
Now we can plug in x=-8
[tex]f'(-8)=\frac{9}{(-8)^{2} }\\f'(-8)=\frac{9}{64}[/tex]
The derivative of f(x) = -9/x at x = -8 is 9/64.
Explanation:To find the derivative of f(x) = -9/x at x = -8, we can use the power rule for differentiation. The power rule states that if we have a function of the form f(x) = x^n, then the derivative of f(x) is given by f'(x) = n*x^(n-1).
In our case, the function is f(x) = -9/x. Rewriting it as f(x) = -9*x^(-1), we can apply the power rule and find that the derivative is f'(x) = (-1)*(-9)*x^(-1-1) = 9/x^2.
Substituting x = -8 into the derivative formula, we get f'(-8) = 9/(-8)^2 = 9/64.
kelly just brought a new pair of shoes! she received a 30% discount, which saved $15 off of the original price. what was the original price of the pair of shoes
Set up an equation:
x * .30 = 15
Divide both sides by .30 in order to determine the value of x
x = 15/.30
x = 115.38
So, the original price of the pair of shoes is $115.38

Solve the systems of equations algebraically
Isolate “y” in one of the equations, then substitute it in the other equation. After you find x, put it in the isolated equation and you’ll find y value.
The value of x = 1 and y = 0.
How to solve the systems of equations algebraically?Consider the given system of equation
4x - 2y = 4 ........(1)
6x - 4y = 6 ........(2)
Solve the system algebraically,
By using the elimination method,
Multiply equation (1) by 2, and we get,
(1) ⇒ 8x - 4y = 8 ............(3)
Subtract equation (2) from (3), we get,
8x - 4y - (6x - 4y) = 8 - 6
Simplifying the above equation, we get
8x - 4y - 6x + 4y = 2
8x - 6x = 2
⇒ x = 1
Substitute x = 1 in (1) and solve for y, we get,
⇒ 4x - 2y = 4
⇒ 4 (1) - 2y = 4
⇒ 2y = 4 - 4
⇒ 2y = 0
⇒ y = 0
Therefore, the value of x = 1 and y = 0.
