Given that 5W = 2P + 3R find the value of P when W = 4 and R = −4

Mathematics
1 answer:
Olenka [21]3 years ago
5 0

Answer:

P = 16

Step-by-step explanation:

Given

5W = 2P + 3R ← substitute W = 4 and R = - 4 into the equation

5(4) = 2P + 3(- 4), that is

20 = 2P - 12 ( add 12 to both sides )

32 = 2P ( divide both sides by 2 )

16 = P

Find the magnitude of −1−5i
ladessa [460]

The magnitude of -1-5i is √26.

<h3>What is the magnitude of -1-5i ?</h3>

Given the complex expression; -1 - 5i

To find the magnitude, we use the formula;

| a+bi | = √[ a² + b² ]

  • a = -1
  • b = -5

| a+bi | = √[ a² + b² ]

| -1-5i | = √[ (-1)² + (-5)² ]

| -1-5i | = √[ 1 + 25 ]

| -1-5i | = √26

Therefore, the magnitude of -1-5i is √26.

If Q(x) = x2 + 3x + 2, find Q(-4).
lord [1]

Q(x)=x^2+3x+2

\\ \sf\longmapsto Q(-4)

\\ \sf\longmapsto (-4)^2+3(-4)+2

\\ \sf\longmapsto 16+(-12)+2

\\ \sf\longmapsto 16-12+2

\\ \sf\longmapsto 4+2

\\ \sf\longmapsto 6
