Answer:
1 mile = 15 seconds
Step-by-step explanation:
3 minutes and 15 seconds = 3 min + 15 sec
1 minute = 60 seconds
15 seconds =15/60 = 0,25 min
then
3minutes and 15 seconds = 3.25 minutes
13miles in 3 minutes and 15 seconds
= 13 miles / 3.25 minutes
= 4 miles / 1 minute
every minute Jose ran 4 miles
then:
4 miles is a 1 minute
1 mile is a T minutes
T = 1*1/4
T = 1/4 minute
1 minute = 60 secomds
1/4 minute = 60*1/4 = 60/4 = 15 seconds
Answer:
11/12

Answer:
1. From sin²θ +cos²θ =1 and sinθ=-2/3, we see that cosθ=√(1-sin²θ) or cosθ=√5/3, where the sign of cosine is positive as it is in Quadrant IV. x lies in 4th quadrant , cos x is +ve. , cos x = √5/3. Answer.
answer : cos x = √5/3
2. 4/3
3. sin (- theta) = - sin (x) so sin x = 1/6
tan = sin / cos = 1/6 / cos = - sqrt35/35 solve for cos
cos = 1/6 * (-35/sqrt35)
= -35 sqrt35 /210
answer : −35/√210
4. The cosine function is an even function, so cos(θ) = cos(-θ).
The relationship between sin(θ) and cos(θ) is sin(θ) = ±√(1 -cos(θ)^2)
For sin(θ) < 0 and cos(θ) = (√3)/4, sin(θ) = -√(1 -3/16) = -√(13/16)
sin(θ) = -(√13)/4 For sin(θ) < 0 and cos(0) = √(3/4), ...
sin(θ) = -√(1 -3/4) = -√(1/4) sin(θ) = -1/2
answer : -13/√4
5. answer : tan^2 θ ⋅ cos^2 θ = 1 − cos^2 θ would be the first step
Answer:
A circle with center C has chords FB and DA which are equidistant from C.
Step-by-step explanation:
A chord is a straight line drawn from a point on the circumference of a circle to another point on the circumference, without passing through the center of the circle.
From the given question, a circle center C has two chords FB and DA that are equidistant from the center of the circle. The distant of FB from C is CG and the distance of DA from C is CE. But CG = CE, which implies that the two chords have equal distant from the center of the circle.
Therefore line CG from center C intersects FB at G, and line CE from center C intersects DA at E.
Here is the answer, the slope for both lines are the same B(or C) is just different.
