Pi/4 radians  
You're looking for the angle that has a secant of sqrt(2). And since the secant is simply the reciprocal of the cosine, let's take a look at that.
 sqrt(2) = 1/x
 x*sqrt(2) = 1
 x = 1/sqrt(2)
 Let's multiply both numerator and denominator by sqrt(2), so
 x = sqrt(2)/2 
 And the value sqrt(2)/2 should be immediately obvious to you as a trig identity. Namely, that's the cosine of a 45 degree angle. Now for the issue of how to actually give you your answer. There's no need for decimals to express 45 degrees, so that caveat in the question doesn't make any sense unless you're measuring angles in radians. So let's convert 45 degrees to radians. A full circle has 360 degrees, or 2*pi radians. So:
 45 * (2*pi)/360 = 90*pi/360 = pi/4 
 So your answer is pi/4 radians.

The point-slope form of the equation of the line that passes through (–9, –2) and (1, 3) is y – 3 = (x – 1). What is the slope-i
Oksana_A [137]

Answer:

the slope intercept form is: y = x+2

Step-by-step explanation:

The general form of point slope form is : y-y₁ = m(x-x₁)

The given equation is: y – 3 = (x – 1)

comparing we get,

m = 1

and solving the equation;

y-3 = x-1

Adding +3 on both sides

y = x-1+3

y=x+2

The general formula of slope-intercept form is : y = mx+b

where m is the slope and b is the y-intercept

so, y = x+2

where m =1 and b=2

so, the slope intercept form is: y = x+2

enot [183]

Answer:

Justin could buy up to 8 cookies.

Step-by-step explanation:

7 * 1.25 = 8.75

15 - 8.75 = 6.25

6.25/.75 = 8.3333333

Which equation represents a proportional relationship?
iren2701 [21]
The equation that represents a proportional relationship is:

y = 32x

Because:

y/x = 32

So that implies that y is directly proportional to x.

Note that other equations represent a proportional relationship in some form, only that the relationship y = 32x is the only direct proportional relationship.
