Y=mx+b, the b is your y-intercept so just rearrange your equation
y=(3/7)x+(2/7)
your y-intercept would be b) (2/7)
Answer:
254/324 which is about 78.4%
Step-by-step explanation:
found area of entire square to be 18² or 324
found area of 4-quarter circles - which equals one circle with radius of 9
A = 81π which is about 70
subtracted 324 and 70 to get 254
ratio of shaded to unshaded is 254 : 324
3x92 = 276 (first 3 exams)
average of at least 90 (90 x 4 = 360)
360 - 276 = 84
Answer
<span>she needs to score at least 84 on the fourth exam </span><span>in order to guarantee a final average of at least 90</span>

Answer:
Sin(t) =
and 
Step-by-step explanation:
The secant function is the reciprocal function of the cosine function. Therefore, given that
then, if
then
.
On the other hand, if cos (t) = 1/2 ⇒ t = ±
Then, the sin(
) =
