Considering only the values of [tex]\beta[/tex] for which [tex]\sin \beta \tan \beta \sec \beta \cot \beta[/tex] is defined, which of the following expressions is equivalent to [tex]\sin \beta \tan \beta \sec \beta \cot \beta[/tex]?
a. [tex]\sec \beta \cot \beta[/tex]
b. [tex]\tan \beta[/tex]
c. [tex]\cot \beta \tan \beta[/tex]
d. [tex]\tan \beta \csc \beta \sec \beta[/tex]
[tex]\large\boxed{Answer:}[/tex]
We will use trigonometric identities to solve this. I will use θ (theta) for the angle.
First of all, we know that cotθ = 1/tanθ. This is a trigonometric identity.
We can replace cotθ in the expression with 1/tanθ.
[tex]sin\theta tan\theta sec\theta \frac{1}{tan\theta}[/tex]
Simplify: 1/tanθ * tanθ = tanθ/tanθ = 1
So now, we have:
[tex]sin\theta sec\theta[/tex]
Next, we also know that secθ = 1/cosθ. This is another trigonometric identity.
We can replace secθ with 1/cosθ in our expression.
[tex]sin\theta \frac{1}{cos\theta}[/tex]
Simplify:
[tex]\frac{sin\theta}{cos\theta}[/tex]
Our third trigonometric identity that we will use is tanθ = sinθ/cosθ.
We can replace sinθ/cosθ with tanθ.
Now we have as our final answer:
[tex]\large\boxed{b.\ tan\theta}[/tex]
Hope this helps!

Answer:
Last option is the correct answer
Step-by-step explanation:
None of these choices are correct.
Correct order would be,
Since,
58° < 59° < 63°
Therefore,
AC < CB < AB
AC, CB, AB (this is the correct order of the sides from shortest to longest.)
What number must you add to complete the square?
x2 + 16x = 3
O A. 16
B. 36
O C. 64
O D. 72
What number must you add to x² + 16x = 3 to complete the square 64: Option C
What is a perfect square?You should be aware that a perfect square is a term that has two common factors
The given equation is x² + 16x = 3
To make the equation a perfect square, Add the square of half of the coefficient of s to both sides
This is to say that (16/2)² = 8² = 64
The equation becomes x²+16x+64 = 3+64
Then you can factorize the equation and simplify the right hand side

Answer: for number 1 its negative 14
Step-by-step explanation:
The figure shown has two parallel lines cut by a transversal: A pair of parallel lines is shown, crossed by a transversal. Angles are identified as 1, 2, 3, 4, 5, 6, 7, and 8. Angles 1-4 are on the top line clockwise from upper left. Angles 5-8 are on the lower line clockwise from upper left. Use the figure to complete the sentence. ∠7 and ____ are alternate exterior angles. ∠2 ∠1 ∠5 ∠8
*see attachement for the diagram of the figure being referred to
Answer:
<1
Step-by-step explanation:
Alternate exterior angles are a pair of angles which are located on the opposite side of the transversal, outside the two parallel lines.
From the figure given, you would see that <7 and <1 lie on opposite side of the transversal and they lie on the outside of the two parallel lines that are cut across by the transversal.
Therefore:
<7 and <1 are alternate exterior angles.

if you were a doughnut shop owner and wanted to find out which doughnut you should make more of, which measure of central tendency would you use.
Answer:
Mode
Step-by-step explanation:
Measures of central tendency:
The 3 most common measures of central tendency are: The mean, the median, and the mode.
The mean is the average value.
The median separates the lower 50% of the values from the upper 50% of the values.
The mode is the value that appears the most times in the data-set.
In this question:
To find the doughnut you should make more, you should have to know which has the biggest interest from clients, that is, the one that is sold the most, which means that the mode should be used.
Answer:
Mode

this is a math question find the complement of 50 degree
Given:
The measure of an angle is 50 degrees.
To find:
The complement of the given angle.
Solution:
We know that the sum of an angle and its complement is 90 degrees.
Let x be the complement angle of 50 degrees.
[tex]x+50^\circ=90^\circ[/tex]
[tex]x=90^\circ-50^\circ[/tex]
[tex]x=40^\circ[/tex]
Therefore, the measure of complement of the given angle is 40 degrees.

Joe has $70 in a savings account. The interest rate is 10% per year and is not compounded,
How much interest will he earn in 4 years?
Use the formula i = prt, where / is the interest earned, p is the principal (starting amount),
is the interest rate expressed as a decimal, and t is the time in years.
Answer:
$28
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 10%/100 = 0.1 per year,
then, solving our equation
I = 70 × 0.1 × 4 = 28
I = $ 28.00
The simple interest accumulated
on a principal of $ 70.00
at a rate of 10% per year
for 4 years is $ 28.00.
