Answer:
101
Step-by-step explanation:
To get the largest weighted sum, you want to give the largest weight to the largest possible digit.
Max( ) = 7·9 +3·8 +2·7 = 63 +24 +14 = 101 . . . . (x, y, z) = (7, 8, 9)
The maximum sum is 101.
Y = 0 i hope that hepled plzz if not right then im so truly sorry
Answer:
(x + 1)² + (y + 5)² = 48
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (- 1, - 5) and r = 4
, so
(x - (- 1))² + (y - (- 5))² = (4
)², that is
(x + 1)² + (y + 5)² = 48 ← equation of circle
Okay, here we have this:
Considering the provided information and grades, we are going to calculate the requested GPA, so we obtain the following:
Then we will substitute in the following formula:

Then:

Finally we obtain that the student's GPA for that term is approximately 3.06.
Answer:
20 degrees
Step-by-step explanation:
we can consider 33 to be the radius of a circle.
31 would then be the cos of the angle in that circle.
the regular cos function is defined for the standard circle with radius 1. so, that would be multiplied by 33 for this circle here.
31 = cos(?) × 33
cos(?) = 31/33 = 0.9393...
? = 20.05 ≈ 20 degrees
