First, to multiplying by a from the both sides. 

au=k

Secondly, to divide by u from the both sides.

au/u as a fraction, and it equals to k/u as a fraction.

it equals a=k/u.

Answer is A. a=k/u.

X, y, z are each a different digit<br> a. Max(2x+3y+7z)=?
dezoksy [38]

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.

Write an equation for the circle with center(-1,-5) and Radius 4sqrt3
irina [24]

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\sqrt{3}, so

(x - (- 1))² + (y - (- 5))² = (4\sqrt{3} )², that is

(x + 1)² + (y + 5)² = 48 ← equation of circle

To compute a student's Grade Point Average (GPA) for a term, the student's grades for each course are weighted by the number of
Liula [17]

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:

GPA=\frac{Grades\ast Credits}{Total\text{ credits}}

Then:

\begin{gathered} GPA=\frac{3.8\cdot5+1.9\cdot2+3.0\cdot5+2.8\cdot4}{16} \\ GPA=\frac{19+3.8+15+11.2}{16} \\ GPA=\frac{49}{16} \\ GPA=3.06 \end{gathered}

Finally we obtain that the student's GPA for that term is approximately 3.06.

HELPPPPP ME OUUTTTTTTT!!!!
klemol [59]

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
