Which measurements of triangle BAC are correct
Answers
The measurements that are correct for the given triangle are
sin C = 9/15
B ≈ 53.13°
Trigonometrical ratiosFrom the question, we are to determine which of the given trigonometrical ratios for the given triangle are correct
The given triangle is a right angle triangle
Using SOH CAH TOA
sin C = 9/15
∴ The option sin C = 9/15 is correct
Also,
Using SOH CAH CAH
tan B = 12/9
∴ The option tan B = 9/12 is NOT correct
To determine the measure of angle B (m ∠B)
From tan B = 12/9
Then,
tan B = 1.33333
B = tan⁻¹(1.33333)
∴ B ≈ 53.13°
Thus, the option B ≈ 53.13° is correct
Hence, the measurements that are correct for the given triangle are
sin C = 9/15
B ≈ 53.13°

The rectangular equation for given parametric equations x = 2sin(t) and y = -3cos(t) on 0 ≤ t ≤ π is [tex]\frac{x^{2} }{4} +\frac{y^2}{9} =1[/tex] which is an ellipse.
For given question,
We have been given a pair of parametric equations x = 2sin(t) and y = -3cos(t) on 0 ≤ t ≤ π.
We need to convert given parametric equations to a rectangular equation and sketch the curve.
Given parametric equations can be written as,
x/2 = sin(t) and y/(-3) = cos(t) on 0 ≤ t ≤ π.
We know that the trigonometric identity,
sin²t + cos²t = 1
⇒ (x/2)² + (- y/3)² = 1
⇒ [tex]\frac{x^{2} }{4} +\frac{y^2}{9} =1[/tex]
This represents an ellipse with center (0, 0), major axis 18 units and minor axis 8 units.
The rectangular equation is [tex]\frac{x^{2} }{4} +\frac{y^2}{9} =1[/tex]
The graph of the rectangular equation [tex]\frac{x^{2} }{4} +\frac{y^2}{9} =1[/tex] is as shown below.

What is the measure of the missing angle?The image attached aside shows us a right triangle with two known side lengths (JL, KJ) and a angle measure (m ∠ K). The measure of the missing angle can be found by using the trigonometric function of cosine:
cos m ∠ J = KJ / JL
cos m ∠ J = 12 / 13
m ∠ J = 22.620°
The measure of the angle J within the triangle JKL is approximately 22.620°.
And the sine of the angle J, which helds the same positive sign than cosine as the angle is in the first quadrant on Cartesian plane, is:
sin m ∠J = √(1 - cos² m ∠J)
sin m ∠J = √[1 - (12 / 13)²]
sin m ∠J = 5 / 13

We conclude the hypothesis test as Alternative Hypothesis if the data would be very unusual if the original assumption about our parameter were correct.
A hypothesis in statistics is a claim or supposition on the properties of one or more variables in one or more populations.

Our hypothesis test will come to one of two conclusions: "reject H0" or "do not reject H0."

Answer:
g = 4
Step-by-step explanation:
if 2 tangent segments are drawn to a circle from the same external point then they are congruent , that is
RJ = RW and MJ = MB and KB = KW
given MR = 6 , then
MJ = 6 - g = MB
given KM = 5 , then
KB = 5 - MB = 5 - (6 - g) = g - 1 = KW
given KR = 7 , then
RW = 7 - KW = 7 - (g - 1) = 8 - g
Then
RJ = RW , that is
g = 8 - g ( add g to both sides )
2g = 8 ( divide both sides by 2 )

Horizontal asymptote y = 1.
What is meant by horizontal asymptote?A slant asymptote has a specific instance known as a horizontal asymptote. A "recipe" for locating a rational function's horizontal asymptote is as follows: Let deg D(x) and deg N(x) represent the degree of the denominator and the numerator, respectively. No horizontal asymptote exists.1) If the degree of the numerator is smaller than the degree of the denominator, the horizontal asymptote is y = 0. 2) The horizontal asymptote is y = c, where c is the ratio of the leading terms or their coefficients if the degree of the numerator and denominator are equal.The denominator of the function, n(x), can be used to find vertical asymptotes by solving the equation n(x) = 0 (note that this only works if the numerator, t(x), is not zero for the same x value). Find the function's asymptotes. The graph exhibits a vertical asymptote at x = 1.Find the horizontal asymptote of the function:

The correct option is B.
Natalie charges $1490 in rent for each home Per month.
According to given information:Natalie charges $1490 in rent for each home.
Given that Natalie owns three homes, her monthly rent will be:
= $4470 (3 * 1490) dollars.
The annual income Natalie receives from her three homes is
=($12 * $4470)
= $53680.
Natalie spends $5850 a year on maintenance for each home.
The total amount Natalie spends annually to maintain her three homes is therefore:
=(3 * 5850) dollars, which comes to 17550 dollars.
Then Natalie's annual income would be
= [(53640 - 17550) dollars]
= 36090 dollars.
The total amount Natalie made over the course of seven years was
