Which relationship in the triangle must be true?
Paul [167]

We'll assume this is an arbitrary triangle ABC.


A) No, the sines of two different angles can be whatever they want


B) sin(B)=cos(90-B)


Yes, that's always true. The "co" in cosine means "complementary" as in the complementary angle, which adds to 90. So the sine of an angle is the cosine of the complementary angle.


C) No, the correct identity is sin(180-B)=sin B. Supplementary angles share the same sine.


D) Just like A, different triangle angles often have different cosines.


Answer: Choice B

Samantha works at an animal shelter. She decides to track the total number of kittens that are brought in. The equation k=4w+3 r
mel-nik [20]

Answer:

B

Step-by-step explanation:

The equation k=4w+3 represents the total number of kittens, where w represents <u>the number of weeks that have passed since Samantha started counting.</u>

This means options C and D are false, because they say <u>the total number of kittens that have come into the shelter</u>.

w represents the number of weeks, weeks can be counted 0 weeks, first week, second week and so on, so option B is true (the domain is all whole numbers) because 0, 1, 2, 3, ... are whole numbers.

Number of weeks can't be a negative number. Since "real numbers" include negatives, therefore, we exclude option A.

In science class, the average score on a lab report is 82 points, with all students scoring within 3.2 points of the average. If
nirvana33 [79]

An equation that represents the minimum and maximum scores is; |x - 82| = 3.2.

<h3>How to write an absolute value equation?</h3>

The absolute value function is defined by:

f(x) = x, x ≥ 0.

f(x) = x, x < 0.

It measures the distance of a point x to the origin.

For this problem, the distance between the minimum and the maximum scores and the mean is of 3.2, that is, the difference between these scores x and the mean of 82 is of 3.2, hence the absolute value equation that represents this situation is given by:

|x - 82| = 3.2.

Graph this function
galben [10]
Solve the equation to get values for x and y.

For example,

When x is 0,

y = 1

You have one point on the line (0,1)

Now, when y = 0,

x = 36/5 = 7.2

You have one more point on the line (7.2,0)

Plot these points on the x and y axes.

Draw a straight line joining these two points. ( I hope you can plot the points)
