If a=15 and b=6, then 9a²-48ab+64b²=?

photoshop1234 [79]

Answer:

Step-by-step explanation:

Value of 'a' = 15

Value of 'b' = 6

Simplifying the expression given in question,

$9a^{2} -48ab+64b^{2}$

$=> (3a)^{2} - 2*3a*8b+(8b)^{2}$

$=>(3a-8b)^{2}$

Putting 'a' & 'b' in above expression ,

$(3a-8b)^{2} = (3*15-8*6)^{2} = (45-48)^{2} = (-3)^{2} =9$

Find the center, vertices, and foci of the ellipse with equation 3x2 + 8y2 = 24

Sveta_85 [38]

Answer:

The center is at (0,0)

The vertices are at ( ( ±2 sqrt(2),0)

foci are ( ±sqrt(5),0)

Step-by-step explanation:

3x^2 + 8y^2 = 24

Divide each side by 24

3x^2 /24 + 8y^2/24 = 24/24

x^2/8 + y^2 /3 = 1

The general equation of an ellipse is

(x-h)^2/ a^2 + (y-k)^2 / b^2 = 1

a>b (h,k) is the center

the coordinates of the vertices are ( ±a,0)

the coordinates of the foci are ( ±c,0), where ^c2=a^2−b^ 2

The center is at (0,0)

a = sqrt(8) = 2sqrt(2)

The vertices are at ( ( ±2 sqrt(2),0)

c = 8 - 3 =5

foci are ( ±sqrt(5),0)

Madelyn has x nickels and y dimes, having a maximum of 15 coins worth no

aliina [53]

9514 1404 393

Answer:

2 nickels, 9 dimes

Step-by-step explanation:

When there are a number of overlapping shaded areas on the graph, I find it convenient to use the reverse of the inequalities. That makes the <em>unshaded</em> area the solution space. Here, the vertices of the triangular solution space are ...

(2, 9), (2, 13), (6, 9)

Any of the grid points within (or on) this triangle is a possible solution. One of them is (2, 9) corresponding to 2 nickels and 9 dimes.

Three solutions are shown:

(x, y) = (2, 9), (3, 10), (4, 11)
