X = number of minutes Maria spends talking on the phone each month
y = Maria's monthly cost

If she talks for x minutes, at $0.01 per minute, then she is charged 0.01*x dollars for those x minutes. This is on top of the $39,99 as the flat fee (which is charged no matter how many minutes are used; even if Maria doesn't use her phone at all)

So that means we add 0.01*x to 39.99 to get 0.01*x+39.99
This expression is equal to y as it is the total cost for that month

Therefore y = 0.01*x+39.99 is the equation
If you want things in function notation, then you'd replace y with f(x) to get
f(x) = 0.01*x+39.99

Suppose sin(A) = 1/4. use the trig identity sin^2(A)+cos^2(A)=1 to find cos(A) in quadrant II. around to ten-thousandth.
larisa86 [58]

In quadrant II, \cos(A) will be negative. So

\sin^2(A) + \cos^2(A) = 1 \implies \cos(A) = -\sqrt{1 - \sin^2(A)} = -\dfrac{\sqrt{15}}4 \approx \boxed{-0.9682}

Which form most quickly reveals the vertex?
Jet001 [13]

Answer:

Step-by-step explanation:

A

A will give you the roots (the x intercepts) just by reading the numbers and doing a small adjustment.

x + 1 = 0

x = - 1            So one of the roots is (-1,0)

x + 5= 0

x = - 5           The other root is (-5,0)

A is not the answer.

B

I have graphed B so that you can see that A is true. See below, Even so, B is in standard form and it is not the answer.

C

The answer is C. The vertex is at 2,27

x - 2 = 0

x = 2

The maximum value is located at 27 which is just read.

That point (2,27) is plotted on the graph.

If line lis parallel to line m, find the value of x and y. (please help taking a test)
castortr0y [4]

Answer:

x=8 and y=21

Step-by-step explanation:

12x-28=7x+12 (the 2 angles are equivalent)

12x-7x=12+28

5x=40

x=8

9y-77 + 12x-28 =180 (the sum of those 2 angles is a flat angle (180°))

9y-77+12*8-28=180

9y=180+28+77-96

9y=189

y=21
