Answer:

Value of d is:

48

Step-by-step explanation:

We are given a matrix M as:

M=\left[\begin{array}{ccc}a&b\\c&d\end{array}\right]

We are given that:

a=19, b=24 and c=38

We have to find the value of d so that M is singular

i.e. determinant of M=0

i.e. ad-bc=0

i.e. 19d-24×38=0

i.e. 19d=24×38

i.e. d=\dfrac{24\times 38}{19}

i.e. d=48

Hence, Value of d is:

48

A rectangle and an equilateral
jek_recluse [69]

Answer:

The area of the rectangle = 50 cm^2.

Step-by-step explanation:

Let the shortest side of the rectangle be x cm.

Perimeter of the rectangle is:

2x + 2(x + 5).

Perimeter of the triangle =  3 * 2x.

As they have the same perimeter:

2x + 2(x + 5) = 3*2x

2x + 2x + 10 = 6x

6x - 2x - 2x = 10

2x = 10

x = 5 cm.

So the area of the rectangle = x(x + 5)

= 5 * 10

= 50 cm^2.

borishaifa [10]

Answer:

Proxima Centauri is 2.478 x 10¹³ miles from Sun.

Explanation:

 Distance of Proxima Centauri to sun = 4.24 light years

 1 light year = 5.9 x 10¹² miles.

 Distance of Proxima Centauri to sun in miles = Distance in light years x 5.9 x 10¹² miles

 So, Distance of Proxima Centauri to sun in miles = 4.2 x 5.9 x 10¹² miles

                                                                               = 2.478 x 10¹³ miles

  So Proxima Centauri is 2.478 x 10¹³ miles from Sun.
