PLEASE HELP!!!!

Mathematics
1 answer:
tresset_1 [31]3 years ago
7 0

Answer:

D

Step-by-step explanation:

y_2 - y_1 / x_2 - x _1

4 - 2 / 3 - (-1) = 2/4 = 1/2

y +4 = 1/2 (x + 3) distributive property

y + 4 = 1/2x + 1.5

y= 1/2x - 5/2 subtraction (you subtract 4 from both sides) (-5/2 = -2.5)

therefore your equation is y = 1/2x - 5/2

hope this helps :)

Which statement describes the behavior of the function f (x) = StartFraction 2 x Over 1 minus x squared EndFraction?.
pashok25 [27]

As x tends to infinity the function f(x) = \frac{2x}{1-x^{2} } approaches zero.

Given function is:

f(x) = \frac{2x}{1-x^{2} }

<h3>What is a function?</h3>

A function f(x) is a rule which relates two variables where x and y are independent and dependent variables.

Divide the numerator and denominator of the given function by x.

f(x) = \frac{2}{\frac{1}{x} -x}

\lim_{x \to \infty} f(x) \\\\\lim_{x \to \infty} \frac{2}{\frac{1}{x} -x}

As we know that as x approaches the infinity 1/x approaches 0.

So, \\\\\lim_{x \to \infty} \frac{2}{\frac{1}{x} -x} =  \lim_{x \to \infty} \frac{2}{-x}

\lim_{x \to \infty} \frac{-2}{x} =0

Therefore, as x tends to infinity the function f(x) = \frac{2x}{1-x^{2} } approaches zero.

2 _ 5 _ 3 = 17 <br> Fill in the blank
siniylev [52]

Answer:

2+5*3=17

Step-by-step explanation:

The blanks should be filled in with a plus (+) and a times sign (*), respectively. To solve this question you must understand PEMDAS. This stands for paratheses, exponents, multiplication, division, addition, subtraction. When solving an equation, operations should be done in this order. Therefore, numbers should be multiplied before they are added.

So, to solve this equation multiply 5*3; this equals 15. Then add 2, which equals 17. And 17=17, so the equation must be true.

The admissions office of a private university released the following data for the preceding academic year: From a pool of 3900 m
Finger [1]

Answer:

a. 0.09 or 9%

b. 0.324 or 32.4%

c. 0.0972 or 9.72%

Step-by-step explanation:

Male applicants = 3900

Female applicants = 3600

Total applicants = 7,500

Proportion of male applicants (m) = 0.52

Proportion of female applicants (f) = 0.48

a. The probability that a random male applicant is accepted and enrolls is given by the probability of a male student being accepted multiplied by the probability of a male student enrolling:

P(a) = 0.30*0.30=0.09=9\%

b. The probability that a random student is accepted is given by the probability of a male applicant being accepted added to the probability of a female applicant being accepted

P(b) = m*0.30+f*0.35\\P(b) = 0.52*0.30+0.48*0.35\\P(b) = 0.324=32.4\%

c. The probability that a random student is accepted and enrolls is given by the probability of a male applicant being accepted and enrolling added to the probability of a female applicant being accepted and enrolling

P(b) = m*0.30*0.30+f*0.35*0.30\\P(b) = 0.52*0.30*0.30+0.48*0.35*0.30\\P(b) = 0.0972=9.72\%
