Find the magnitude of the vector from the origin to (8. - 6) and write the vector as the sum of unit vectors.

Kay [80]

The magnitude of the vector from the origin is 10

The unit vector in of the vector from the origin as (8/10, -6/10

<u>Step-by-step explanation:</u>

<u>1.Finding the magnitude,</u>

we have the formula,

magnitude=√a²+b²

we have the values as a=8 and b=-6

Finding the magnitude we get,

magnitude=√a²+b²

magnitude=√8²+6²

magnitude=√100

magnitude=10

The magnitude of the vector from the origin is 10

<u>2.Finding the unit vector</u>

Divide by the magnitude

Unit vector: (8/10, -6/10)

The unit vector in of the vector from the origin as (8/10, -6/10

Evaluate the following expression (a + b)^0

elixir [45]

Answer:

So, $(a + b)^0=1$

Step-by-step explanation:

$(a + b)^0$

To evaluete this expression we apply exponential property

$x^0=1$

IF any expression has exponent 0 then the value is 1 always

for example, $3^0 =1$

$5^0=1$

$(x+2)^0=1$ because exponent is 0

So, $(a + b)^0=1$

Which equation is true?

ch4aika [34]

Answer : $9x^2 - 25 = (3x - 5)(3x + 5)$

(1) $9x^2 - 25 = (3x - 5)(3x - 5)$

Use FOIL method to mulitply (3x – 5)(3x – 5)

$(3x - 5)(3x - 5) = 9x^2 - 30x + 25$

(2) $9x^2 - 25 = (3x - 5)(3x + 5)$

Use FOIL method to mulitply (3x - 5)(3x + 5)

$(3x - 5)(3x - 5) = 9x^2 - 15x + 15x - 25 = 9x^2 - 25$

(3) $9x^2 - 25 = -(3x + 5)(3x + 5)$

Use FOIL method to mulitply -(3x + 5)(3x + 5)

$-(3x + 5)(3x + 5) = -(9x^2 + 30x + 25) = -9x^2 -30x -25$

(4) $9x^2 - 25 = -(3x + 5)(3x - 5)$

Use FOIL method to mulitply -(3x + 5)(3x - 5)

$-(3x + 5)(3x - 5) = -(9x^2 - 25) = -9x^2 + 25$

So equation 2 is true
