Answer:

(-4-3i) (- 4 + 3i) = 25

Step-by-step explanation:

Notice in the graph that z1 has a real component of -4 and an imaginary component of -3.

Then we know that:

z_1 = -4-3i

By definition for an imaginary number of the form a-bi its conjugate will always be the number a + bi

So the conjugate of z_1 is:

-4 + 3i

The product of both numbers is:

(-4-3i) (- 4 + 3i) = 16-12i + 12i-9i ^ 2\\\\(-4-3i) (- 4 + 3i) = 16-9 (-1)\\\\(-4-3i) (- 4 + 3i) = 16 + 9\\\\(-4-3i) (- 4 + 3i) = 25

Answer:

The product is 25

Step-by-step explanation:

we know that

The complex number z1 is equal to

z1=(-4-3i)

we know that

To find the complex conjugate of (-4 - 3i) we change the sign of the imaginary part

so

The conjugate is equal to (-4+3i)

therefore

(-4-3i)(-4+3i)=16-9(-1)=25

It is 397.8 bc if u make 530.4 a fraction = 530.4/1 then u just multiply it by 3/4 u will get 1591.2/4 then u simply reduce it by dividing ( top in , bottom out ) and u get 397.8

Can someone solve this for me?
Naya [18.7K]

Answer:

-1/2

Step-by-step explanation:

Slope is defined as change in x/change in y.

The x changed by 1/8-(-1/4)=3/8 and the y changed by -4-(-1/4)=(-3/4).

Now, divide the 2 fractions:

(-3/4)/3/8 = -3/4*8/3 = -4/8 = -1/2

PLEASE HELP ME WITH THIS QUESTION
GREYUIT [131]

Answer:

x = 2√58

Step-by-step explanation:

Pythagoras' Theorem:  a² + b² = c²

(where a and b are the legs and c is the hypotenuse of a right triangle)

Find the height of the triangle by using the base and hypotenuse of the smaller interior triangle and Pythagoras' Theorem:

   a² + b² = c²

⇒ a² + 6² = (6√2)²

⇒ a² = (6√2)² - 6²

⇒ a² = 36

⇒ a = 6

Now we have the base and height of the larger interior triangle, we can calculate x:

    a² + b² = c²

⇒ 6² + 14² = x²

⇒ x² = 232

⇒ x = √232

⇒ x = 2√58
