Hey there!!

How do we find the determinant ?

Ans = ad - bc : determinant

In the given matrix ,

a = -5

b = 1

c = 1

d = 4

Determinant = ( -5 ) ( 4 ) - ( 1 ) ( 1 )

... - 20 - 1

... -21

Option ( c )

Hope it helps!

18) If the straight line y=m X touches the circle (x - 2)^2 + (y - 6)^2 = 4, then m= ......
fenix001 [56]

Answer:

(8) d. 4/3    (9) a. (X - 4)^2 + (y-4)^2= 25

Step-by-step explanation:

8. CENTER OF CIRCLE: O (2,6)

     radius of circle : r = √4 = 2

if m = 4/3 line: y = 4/3 x

perpendicular distance (d) from center of circle to line y = 4/3 x is

d = |((4/3 x 2) + (-1) x 6)| / √((4/3)² + (-1)²) = |(-10/3)| / √(25/9) = (10/3) / (5/3) = 2

d = r means line touch with circle

9. center of circle is the intersection of the diagonals of rectangle (4,4) and its radius is 5 (illustrated)

the equation of circle: (X - 4)^2 + (y-4)^2= 25

Find the equation of the linear function represented by the table below in slope-intercept form.
Y_Kistochka [10]

Answer:

y= 8x +7

Step-by-step explanation:

<u>slope-intercept form:</u>

y= mx +c, where m is the gradient (or slope) and c is the y-intercept.

Since it is a linear function, the gradient of any 2 points would be equal.

gradient =  \frac{y1 - y2}{x1 - x2}

Thus, gradient of the line

=  \frac{39 - 23}{4 - 2}  \\  =  \frac{16}{2}  \\  = 8

Subst. m=8 into the equation:

y= 8x +c

To find the value of c, substitute a pair of coordinates.

When x=0, y= 7,

7= 8(0) +c

c= 7

Thus, the equation of the linear function is y= 8x +7.
