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

Factor out the coefficient of the variable -3.6m + 10.8
MA_775_DIABLO [31]

Answer: -1

Step-by-step explanation: First, factor out 3.6. You should get -m+3. Since the coefficient is just the number being multiplied to the variable (which is m here), your coefficient should be -1 because m is being multiplied to -1 to make -m. Hope this helps!

The Pythagorean Theorem- Find the Missing Length:
drek231 [11]

The miles he drove North on Avenue B is 24 miles.

<h3>What is Pythagoras theorem? </h3>

According to the Pythagoras theorem, the square of the hypotenuse is the sum of the square of the opposite sides.

The Pythagoras theorem: a² + b² = c²

Where:

  • a = length
  • b = base = 7 miles
  • c = hypotenuse = 25 miles

<h3>How many miles did he drive north of Avenue B? </h3>

25² - 7²

625 - 49 = 576

√576 = 24 miles

Please find attached the required diagram. To learn more about Pythagoras theorem, please check: brainly.com/question/14580675
