Vertical angles are lines going up and down.

So the answers would be V, Q, and S.

Write an equation in slope for a line that passes through (3,4) (and has a y intercept of -8)

Vlad [161]

Answer:

Part 1) The equation in slope intercept form is $y=4x-8$

Step-by-step explanation:

Part 1) Write an equation in slope-intercept form for a line that passes through (3,4) (and has a y intercept of -8)

we know that

The equation of a line in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

$b=-8$

$point\ (3,4)$

substitute

$4=m(3)-8$

solve for m

$4+8=3m$

$3m=12$

$m=4$

therefore

$y=4x-8$

(__)^2=(csc x-1)(csc x+1)

Aleksandr [31]

(csc x-1)(csc x+1)=csc²x-1²=csc²x-1=(1/sin x)² -1=1/sin x² - sin²x/sin²x=
=(1-sin²x)/sin² x = cos² x/ sin² x = (cos x/sin x)²= (cot x)²

David estimates that he will have expenses totaling $24,870 for one year of college, He will receive$7,560 in grants. Howmuch wi

noname [10]

Since there are 2 semesters per year we have:

(1/2)(24,870 - 7,560) = $8,655

David would have to contribute $8,655 per semester.

What is the experamental probability that the coin lands on heads?

sammy [17]

Answer:

The experamental probability that the coin lands on head is 50 %

Step-by-step explanation:

Given:

Experiment:

A coin is Toss

Let the Sample Space be 'S' that is total number of outcomes for a coin has been tossed = { Head, Tail }

∴ n ( S ) = 2

Let A be the event of getting a Head on tossing a coin i.e { Head }

∴ n( A ) = 1

Now,

$\textrm{Probability} =\frac{\textrm{outcomes for the experiment}}{\textrm{total number of outcomes}}$

Substituting the values we get

$P(A) = \frac{n(A)}{n(S)} \\\\P(A) = \frac{1}{2} \\\\P(A) = 0.5\\\\P(A) = 50\%$

The experamental probability that the coin lands on head is 50 %
