Answer:

QUESTION 1-  sin\theta =-\frac{4}{5}

QUESTION 2-  cos\theta =-\frac{5}{\sqrt{14} }

QUESTION3- sinx =-\frac{1}{\sqrt{17} }

Step-by-step explanation:

For Question 1

From the given point(-3,4), we can deduce the following.


The point is in the 2nd quadrant.

The right-angled triangle which is formed has a hypotenuse of length 5 by Pythagoras theorem whrere B=3 and P=4.


The third quadrant are from 90° to 180° in which the angle lie.

so  sin\theta =-\frac{P}{H}=-\frac{4}{5}


For Question 2

From the given point(-4,-5), we can deduce the following.


The point is in the 3rd quadrant.

The right-angled triangle which is formed has a hypotenuse of length  \sqrt{14} by Pythagoras theorem whrere B=-4 and P=-5.

The third quadrant are from 180° to 270° in which the angle lie.

so  cos\theta =-\frac{P}{H} =-\frac{5}{\sqrt{14} }


For Question 3

The line with equation 4b + a = 0 , we can deduce that the value of b=-\frac{a}{4}

slope of line  tan\theta =-\frac{P}{B} =-\frac{1}{4}

Hypotenuse of length \sqrt{17} by Pythagoras theorem whrere B=4and P=1.

so  sinx =-\frac{P}{H} =-\frac{1}{\sqrt{17} }.

For a perfectly symmetrical distribution with a mean of 50, what is the value of the median?
Lelechka [254]

In a set of data, if the data is perfectly symmetrical then the mean is equal to the median. In this case, the median would be 50.

For example, consider the data set: {25, 50, 75}

The mean is going to be 50 because \frac{25+50+75}{3} = 50

The median is also 50 because that is the middle number when ordered numerically.

Hope this helped! Let me know if you have any more questions.

What is the definition of csc θ ?
Greeley [361]
Csc is the inverse of sin. This means the formula in regards to a triangle for csc is h/o, unlike o/h for sin. csc can also be knows as 1/sin.

What is the awnser to this question because I don't understand
Virty [35]
Pemdas 1. parentheses: everything is already in parentheses. so next is exponents. 10×-2 is -20. and 10×6 is 60. so 4×-20 is the next step. it equals -80. and then 3×60 is 180. lastly,add -80 and 180 together. the answer should be 100 if i did that correctly.

PLZZ HELPP!!! WILL GIVE BRAINLIEST!!!
lutik1710 [3]

Answer:B. 2x^2 + 4x - 1 - 9/4x + 1

Step-by-step explanation:

f(x) = 8x^3 + 18x^2 − 10

g(x) = 4x + 1

We want to determine f(x)/g(x). We would apply the long division method. The steps are shown in the attached photo.

The correct answer is

2x^2 + 4x - 1 - 9/4x + 1
